Is there a pin-compatible replacement for FRC2512F1003TS?

Yes, parts like RC2512FK-7W100KL are pin-compatible in the same 2512 package. However, they are not electrically identical. You must verify that the different electrical parameters, like TCR, are acceptable for your design.

What risks should I check before replacing FRC2512F1003TS?

When replacing FRC2512F1003TS, verify three key parameters: 1. Power Rating: Ensure the replacement can handle at least 1W. 2. Tolerance: The original is ±1%; using a ±5% part may affect precision. 3. TCR: The original is ±100ppm/°C; a higher TCR can cause resistance to drift more with temperature.

FRC2512F1003TS Alternatives, Datasheet & Cross Reference | FOJAN

Finding a substitute for the FRC2512F1003TS 100kΩ 1W 1% resistor requires checking power rating, tolerance, and TCR. Several 2512 package alternatives exist, but may require design review for parametric differences.

AI replacement insight

Electrical riskmedium

TCR and tolerance mismatches require review.

Package risklow

Several candidates match the 2512 package.

Sourcing risklow

Multiple vendors produce similar parts.

Can it be replaced directly?

No direct drop-in replacement was found. The best candidates require reviewing the impact of a weaker Temperature Coefficient (TCR) or wider resistance tolerance.

Best replacement path

RC2512FK-7W100KL offers a power upgrade to 2W but has a weaker TCR (±200ppm/°C). It is the closest match if the application is not sensitive to temperature drift.

Main risk

The primary risk is substituting a part with a weaker Temperature Coefficient (TCR) or wider tolerance (±5% vs ±1%), which can impact circuit accuracy and stability.

Recommended alternatives

A 2512 package resistor with same resistance and tolerance, but higher power rating and weaker TCR.
