Pin-to-pin replacement in 48 hours. Don't redesign your board because of one end-of-life part.

We’ve validated 5,000+ replacements. We know what actually works versus what 'works on paper.' We check not only electrical parameters, but also availability, lead time, and second source.

Upload BOM to Check Replacements
Unique value proposition

Not a replacement catalog — verified replacements. Every part works on a real board.

The problem with existing substitution databases: they say a part is parametrically equivalent but don't verify how the chip behaves in your layout. The result is a part that 'fits' but the board fails testing.

Replacement Process

  1. 1

    Current BOM Audit

    We analyze your specification. We identify components at risk: end-of-life, from unfriendly countries. We prioritize by criticality.

    1–3 days
  2. 2

    Alternative Search

    We search our verified replacement database. If no drop-in exists, we search parametric catalogs of Russian and Chinese manufacturers. We check pinout, voltages, currents, temperature range, and package.

    1–2 days
  3. 3

    Verification

    We order samples and verify them on a test board. We measure real-world parameters and compare them to the datasheet. Report: replacement confirmed / circuit modification required / no alternative found.

    3–7 days
  4. 4

    Documentation Update

    We update the BOM, schematic, and specification. We issue an Engineering Change Order (ECO) if needed. We support the first production run with the new components.

Features and details

Pin-to-Pin Replacements

No board redesign — swap only the component

Prototype Verification

Every replacement is tested on a real board in a temperature chamber

5,000+ Part Database

Continuously updated database of verified Russian and Chinese alternatives

GOST-R Documentation

We prepare the package for certification and military acceptance testing

Frequently asked questions

How quickly do you find an analogue?+
Initial search via our verified replacement database — up to 48 hours. If the analogue needs bench verification, timing increases by 3–7 days.
What if no pin-to-pin analogue exists?+
We'll suggest the closest parameter match and estimate schematic or layout rework. In some cases, several components can be replaced by one.
