I'm looking for MOLEX 90130-3120  connector library, which is not directly available from jlcpcb or any other tscircuit repositories. It is available from ultra-librarian. What is the easiest method to convert it to tscircuit library? Should I download KiCAD files and try to convert them or are there any other simpler methods?

Yea probably via kicad

You can directly import kicad files and footprints

https://github.com/tscircuit/kicad-converter, https://github.com/tscircuit/kicad-to-circuit-json : I'm aware of these two repos. Do I have to use kicad? My assumption is that the circuit json converter from above repos will directly ingest the library files available from ultra-librarian..

You can literally just import it

Those projects also work though

We can add a using Ultra Librarian guide- havent used them much lately, lmk if it is a PITA we will make it easy

I tried this direct import approach(roughly 3 months ago). Circuit rendering with kicad components were painstakingly slow that time.. Let me go through all approaches.. Will try to document a stable workflow and share..

<@757706909351411845> I could successfully create tscircuit component for the pinheader. Here are few of the observations:
```

1. Obtained the kicad library from ultralibrarian 
2. Converted kicad footprint to tscircuit tsx code 
    - First tried with `kicad-component-converter` npm package. But due to package dependency issues, dropped this approach 
    - Then used the online tool: https://kicad-component.tscircuit.com/ 
        - Uploaded kicad_mod file to the webpage and downloaded the .tsx component file
3. The converted code contains only footprint information. Schematic information needs to be attached separately.
    - molex_901303120 is a simple connector. So asked AI agent to update the molex_901303120.tsx file refering to other libraries available.
    - Since there are no datasheet related information required to define pin names/numbers, agent could generate necessary code in one go.
    - Generated component worked seamlessly with the existing circuit, in first try
```

(This is taken from my notes. Sorry for being verbose.. 🙂 )

Is there any public registry where I can upload generated components, so that everyone can use it in future?

## Seve — 2026-07-04T16:03:48.771000+00:00

Yes you can publish to the tscircuit.com registry with “tsci push”

I appreciate the writeup!!!

## Seve — 2026-07-04T16:04:40.686000+00:00

We will review how we can make this more straightforward
