OMPONENTS

We help buyers get around long component lead times. Eighteen product lines are defined; none has been released yet, so every line below is marked Draft until it goes on sale.

≡

FFF direct equivalents. Drop into your existing board, panel or assembly in place of a known brand's part — no redesign or software change.

⚒

Made-to-order parts. Built by small local shops to your drawing or specification.

⌬

Firmware ports. Your firmware moved to an in-stock microcontroller.

✎

Specification & sourcing. For higher-cost items: a better spec or a second qualified maker.

HOW TO ORDER

Send a request with:

The part you can’t get (maker and part number) and its quoted lead time.
Your quantity, target date and delivery location.
Any approvals the part must carry (UL, CE, VDE, automotive).
For made-to-order parts: your drawing, or the specification to build from.

We reply with a candidate, a datasheet comparison against your original, and a quote with a lead time.

OUR COMMITMENTS

No false equivalence claims. Listed as an FFF direct equivalent only when form, fit and function match the original’s datasheet on the points above.

Data with every equivalent. A datasheet comparison and test results you can add to your approved vendor list.

Traceability. Parts sourced through traceable channels only.

Approvals stay yours to confirm. We don’t claim UL, CE or other listings we don’t hold.
