| Ref | MPN | Status | Substitute | Note |
|---|---|---|---|---|
| U4 | LM358P | Act now | LM358PWR | Obsolete PDIP package. SOIC substitute is active, same electrical spec. |
| U12 | MCP2551-I/SN | Act now | MCP2561FD-H/SN | CAN transceiver discontinued. Pin-compatible successor, firmware unaffected. |
| U8 | ADS1115IDGST | Watch | — | Marked NRND by manufacturer. Still in production — worth planning a migration path. |
| C22 | GRM188R71H104KA93D | Watch | — | Active, but this dielectric/case combination is on tightening allocation. |
| Q7 | 2N3904 | Healthy | — | Widely second-sourced. No action needed. |
| R14, R15 | RC0603FR-0710KL | Healthy | — | Standard passive, broad availability across distributors. |
This dual op-amp's through-hole package was discontinued by the manufacturer. The SOIC-8 version (LM358PWR) is active, electrically identical, and already the more common package in current designs — this is a low-risk swap once your assembly process accounts for the footprint change.
Your CAN transceiver is fully discontinued with no further stock expected from authorized channels. The suggested replacement is pin-compatible and doesn't require a board revision, though it's worth a quick bench check before committing to production — different internal timing characteristics on some CAN transceivers can occasionally affect edge cases.
Every real report is built from your actual BOM — this example just shows the format. Substitutes shown here are illustrative and haven't been independently re-verified for this page.
