Is there a pin-compatible replacement for FRC0402F1503TS?

No pin-compatible replacements that meet the required 1.5x power safety margin have been identified. Several 0402 parts exist with the same power rating, but they do not offer an upgrade path and are therefore rejected.

What risks should I check before replacing FRC0402F1503TS?

Key risks include package size mismatch, which requires PCB layout changes. Also, verify the candidate's power derating curve and maximum voltage ratings are suitable for your application's operating conditions.

FRC0402F1503TS Alternatives, Datasheet & Cross Reference | FOJAN

FRC0402F1503TS is a general-purpose 150kΩ 1% 1/16W thick film resistor in a 0402 package. While no direct replacements meet all safety margins, several functional alternatives with higher power ratings are available in larger packages.

AI replacement insight

Electrical risklow

Resistance/tolerance match, and power/voltage ratings are superior.

Package riskhigh

All viable options are in larger packages, requiring a board redesign.

Can it be replaced directly?

No direct, pin-compatible replacements meet the engineering rule for increased power handling (≥1.5x). Yageo's RC0402FR-07150KL is electrically identical but does not provide a power margin.

Best replacement path

Functional alternatives in larger packages (0603, 0805) offer higher power ratings. The 0603WAF1503T5E is the closest in size.

Main risk

The primary risk is physical incompatibility; all viable alternatives are in larger packages, requiring a board redesign.

Recommended alternatives

Functional alternative with higher power and voltage ratings in a larger 0603 package.
