Is there a pin-compatible replacement for FRC2512F1503TS?

Yes, several parts share the same 2512 package and pinout. However, they are not electrically identical, featuring a ±5% tolerance instead of the original's ±1%. Engineering review is required.

What risks should I check before replacing FRC2512F1503TS?

The main risk is the change in resistance tolerance from ±1% to ±5%. Verify that your circuit can perform correctly with this wider tolerance. Also, confirm secondary parameters like temperature coefficient (TCR) if critical.

AI replacement insight

Electrical riskmedium

Tolerance change from ±1% to ±5% requires circuit analysis.

Package risklow

Alternatives share the same 2512 package.

Can it be replaced directly?

No direct drop-in replacement with identical key parameters was found. Alternatives require review, primarily for the looser resistance tolerance.

Best replacement path

Parametric alternatives with a wider tolerance (±5%) are available in the same 2512 package.

Main risk

The primary risk is the relaxed resistance tolerance from ±1% to ±5%, which may affect circuit precision.

Recommended alternatives

A cross-vendor alternative in a 2512 package with matching resistance and power, but a relaxed ±5% tolerance.
