# Why use an Altium DBLib over an Integrated Library?
Altium Database libraries make you design your schematic with the part you are going to use, rather than a generic part with the same footprint. Rather than selecting "RJ45 Jack" you instead select Amphenol Commercial Products part number RJCSE538001. This is reflected in your BOM - the entire BOM fills itself out, meaning no more trying to remember exactly what part you actually meant to put in there was, or what voltage that capacitor was.
Prior to using a DBLib, it would often take me half a day to fill out the bill of materials. I'd have to find each resistor on the supplier's website, list it down with the supplier's part number, manufacturer, manufacturer name, etc... Now I just generate the BOM in the output job, and everything is done. No more trying to remember "was that 33uF cap 25V or 50v?", or finding out after the fact that no, that capacitor isn't available as a 47uF 50V variant in that package, despite the fact you were sure it was!
The Celestial Altium Library database is cloud-hosted; as new components are added to the library, they are immediately available in Altium. The library's schematic symbols and PCB footprints are hosted in GitHub allowing you to quickly clone the latest library files to your computer if they are needed for the new components.
A database library creates the linkage between a schematic symbol and PCB footprint on your computer, and also provides all of the technical parameters and pricing data for a component. This connection allows the library to contain every real-world capacitor, resistor, and other component types, with relatively few files on your computer.
Basically: You save time on the design, and you greatly reduce errors occurring from specifying a part you didn't actually use (who hasn't accidentally specified a right angle connector variant when it was really vertical on the board - oops?)
Altium Database libraries make you design your schematic with the part you are going to use, rather than a generic schematic symbol/footprint combination. Rather than selecting "RJ45 Jack," you instead choose Amphenol Commercial Products part number RJCSE538001. This component selection is reflected in your Bill of Materials - the entire BOM fills itself out, meaning no more trying to remember exactly what part you intended to put in there was, or what voltage that capacitor was. Even if you are using an ActiveBOM in your project, the library will save you time as you do not need to set component properties after placing each component.
Without the Celestial Altium Library, you might find yourself looking for passive components on supplier websites to find a low-cost option, and then searching for those parts in the Manufacturer Part Search panel in Altium. Once you find the part you want, you can assign the properties to the schematic symbol in your project. With the library, however, you can rapidly sort through thousands of components to narrow down the list of relevant parts and then place the cheapest in-stock option directly into your design - all with Altium. Components added with the library will generate an excellent bill of materials for your project with or without ActiveBOM.
Save time on the design, and significantly reduce errors by placing real-world parts directly from the library.
# The Library
### Why use this library over something like Ultra Librarian?
Ultra librarian doesn't have high quality 3d models or parametrics. If all you need is basic footprint, Ultra librarian is what you want. If you want something open source, ultra high quality parts and with all the data fields you desire.. then you'll probably really like this library.
# Why use the Library?
If you're integrating your electronic design into a housing or designing injection moulded cases for it - you need accurate 3d models or your mechanical engineers will spend a lot of time making sure the case fits your design files.
## Data
### Data
All parts in the database are matched with every relevant parameter that Digi-Key has for the part, so you can search/filter within Altium for the part you require. If you are looking for low Rds(on) N-Ch fets, just add the Rds(on) column to the Altium library window and sort by it.
All components in the database contain all relevant technical parameters, allowing you to search/filter within Altium for the part you require. If your design calls for a 1.0uF, 25V 0603 ceramic capacitor, open the 0603 ceramic capacitors list, group by value, then by voltage, and sort by price to find the cheapest option available.
Every part has a link to the part on Digi-key, and has a link to the datasheet for the part for ease of design. Both the Digi-Key part number, price, and manufacturer name/part number are stored, now your BOM will be completely filled out automatically.

Each component in the database contains a link to supplier pages and a link to the datasheet allowing rapid access to reference materials. As all technical parameters and pricing data is available, your BOM can be populated automatically with all relevant information for purchasing.
### Footprints
Every part has a footprint created to match it's manufacturers recommended footprint by the manufacturer, or lacking that, an IPC Compliant footprint for the manufacturers specific package sizing. There are no generic footprints within this library, everything is manufacturer specific.
Every component has a footprint that matches the manufacturer's recommended footprint, or if a recommendation is not available, an IPC Compliant footprint for the specific package sizing. Only highly standardized passive components utilize generic footprints; all other parts have manufacturer-specific land patterns.
Every footprint has a high quality, dimensionally accurate, accurately coloured 3d model. For complex parts (connectors like modular jacks), the manufacturers model is preferred however is always fully coloured and checked for accuracy against their drawings and modified as required. I've found issues with the accuracy of the manufacturer issued model from most models, where they do not match the datasheet - every instance has been checked with the manufacturer and many have re-issued their 3d models because of these checks.
Basic parts (TSSOP/SOP/Resistors etc) I have created every model from scratch in SolidWorks, if the manufacturers dimensions vary from the JEDEC standard, they receive their own version of the 3d model (see SOT-23-3..) For ultra basic parts with no features (QFN/DFN), a black basic Altium 3D extrusion is used of the correct size.
Every part's centre position is where the Pick and place head should grab the part. For companies running their own Pick and Place machine, this is very convenient compared to centres at pin 1/centre of pads - your pick and place export list now has centres in the correct location.
Each footprint features a high quality, dimensionally accurate, correctly colored 3D model. Every 3D model in the library is created from scratch to the manufacturer's drawings. This attention to detail ensures excellent 3D collision checking and eases MCAD integration when designing enclosures and associated parts.
Every part's center position is where a pick and place machine's head should collect the component. For companies running an in house Pick and Place machine, this is very convenient and allows faster machine setup. Your pick and place export list for products built with the Celestial Altium Library contains centers in the correct location.
### Symbols
Every symbol in the library is somewhat standardised as to where pins are located, such as VCC in the top left, GND in the bottom left, user function pins on the right (controllable inputs/outputs). Standard protocols like SPI have the pins in the same order in every part - however manufacturer datasheet labeling is kept (DOUT rather than MISO for example) to make it easier to reference the datasheet. All components within a database category should have similar if not identical layouts/pin groupings where possible. This makes it much easier to switch out components.
All passive components, such as resistors and capacitors all have the same size symbol lead span, keeping your schematics tidy.
# What components are contained in the library?
There are currently over 27000 parts in the library, this number sounds quite large but when you consider you need every value of resistor in 1%, 0.5%, 0.25%, 0.1% and 0.05%, in 0201, 0402, 0603, 0805 and 1206... you're now looking at over 5000 resistors.
Generally only SMT parts are in the library, except connectors, buttons and displays which have a mixture.
There are currently parts from over 120 manufacturers in the database.

Library symbols are standardized as much as possible. This standardization ensures you will find pins where you expect them to be, such as VCC in the top left, GND in the bottom left, user function pins on the right (controllable inputs/outputs). Standard protocols like SPI have the pins in the same order in every part where other library standards don't have a higher priority. All components within a database category have similar pin layouts/groupings where possible. This preciseness makes it extremely easy to read and follow schematics created with the library.
All passive components, such as resistors and capacitors, all have the same size symbol lead span, keeping your schematics tidy.
