Replacing Western components without redesigning the board

We find locally available analogues with matching footprints and parameters. Then we verify on a real board, not just in a datasheet comparison tool.

Request a substitute search
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.

How we substitute

  1. 1

    You send the BOM

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

  2. 2

    We search for analogues

We query our database of 12,000+ verified replacements. If no match is found, we search our extended supplier network.

  • 3

    We test the candidate

    The selected analogue is tested on a reference board. We run power-up, signal integrity, and thermal tests. Only verified parts make it to the report.

  • 4

    You receive the report

    You get a detailed report: pin compatibility, parameter comparison, test results. Plus certification documents for Russian compliance.

  • Features and details

    Database

    12,000+ verified replacement pairs — every one tested on real hardware

    Certification Docs

    Full documentation package for RF certification: specifications, certificates, and CU TR declarations

    Bench Testing

    Every recommended analogue is power-tested and signal-verified before we present it

    Pin-to-Pin Focus

    We prioritize footprint-compatible replacements. If none exist, we estimate the layout rework cost

    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.
