Is there a pin-compatible replacement for CR6045H-100M?

CR6045-100M from the same manufacturer shares the same 6045 package and pinout. However, it is a downgrade with lower saturation current (3.0A vs 4.5A) and higher DCR, which may affect performance and efficiency. Full re-validation is required.

What risks should I check before replacing CR6045H-100M?

Key risks include: 1) Package mismatch, as most alternatives are larger and require a PCB redesign. 2) Electrical stress, if using a downgrade like CR6045-100M, ensure its lower current ratings are sufficient. 3) Thermal performance, as DCR changes will affect heat dissipation.

Most alternatives are not form-fit and require a PCB redesign.

Electrical riskmedium

The only form-fit option is a significant electrical downgrade.

Sourcing risklow

Multiple vendors offer functionally similar parts in various packages.

Can it be replaced directly?

No direct, drop-in upgrade has been identified. CR6045-100M is a form-fit downgrade, while all other candidates require a new PCB layout.

Best replacement path

For a new design, select a functional alternative with a higher current rating like TMPA1265SP-100MN-D. For an existing design, carefully evaluate the downgrade risk of CR6045-100M.

Main risk

The primary risk is physical incompatibility, as most electrically superior alternatives are in larger packages.

Recommended alternatives

Electrically superior upgrade but in a much larger package, requiring a board redesign.

Questions & answers

For new designs, parts like TMPA1265SP-100MN-D offer superior current handling (17A Isat) and lower DCR, but require a larger PCB footprint (12.6x13.5mm). For existing boards, CR6045-100M fits the footprint but has lower current ratings and must be carefully evaluated.
