01 · COLLECT
Only official sources: migration guides, compatibility statements, vendor cross-reference databases, second-source datasheets and parametric tables.
VERIFICATION PROCESS
Evidence, or it isn't a match.
3,838 cross-references are graded against traceable source material — 544 official documents linked. Differences are disclosed before compatibility is claimed.
02 · ARCHIVE
The source document or vendor record is retained on file. A claim we cannot trace does not earn a high-confidence grade.
03 · GRADE
Each match receives one of four compatibility grades plus a confidence level tied to the strength of its evidence.
04 · DISCLOSE
Known differences are shown alongside the match so engineers can identify the checks required before validation.
Four grades
P2PPin-to-pin
Drop-in candidate. Official compatibility evidence or a second-source datasheet is required; residual differences are still listed.
PINPin-compatible
Same package and pinout. Firmware porting or peripheral review is required and should follow the cited migration guide.
FUNCFunctional
Functional equivalent. A board or BOM change may be required; verify the alternative against its datasheet.
REFReference
Closest parametric match only: a qualified starting point for engineering evaluation, never presented as drop-in.
Evidence class registry
Real source classes represented in the current database.

HONESTY RULE
Differences first. We list what's not identical before we claim what is.NEVER COUNTS AS P2P EVIDENCE
- Community reports and forum anecdotes
- Manufacturer marketing claims without technical support
- Part-number similarity alone

CORRECTIONS LOG
Data changes are recorded, not silently overwritten. Report an error to sales@senneon.com — verified corrections land here.
2026-07-24 — Indexation quality gate introduced: only cross-references with itemized differences, parametric data, or official-document-backed P2P grades enter search indexes. Data-verified dates now shown per page and per evidence row.
2026-07-13 — Source refresh: GigaDevice, Artery, HK, 3PEAK and SGMicro records re-fetched; evidence documents re-archived.
