Is there a pin-compatible replacement for RC2512FK-7W100KL?

Yes, parts in the 2512 package like Yageo's RC2512JK-7W100KL are pin-compatible. However, you must verify electrical parameters like tolerance before substitution.

What risks should I check before replacing RC2512FK-7W100KL?

The main risk is tolerance mismatch. The target is a ±1% precision resistor. Using a ±5% part may affect circuit performance. Also, verify the Temperature Coefficient (TCR) for any cross-vendor alternative.

RC2512FK-7W100KL Alternatives, Datasheet & Cross Reference | Yageo

The Yageo RC2512FK-7W100KL is a 2W, 100kΩ, 1% precision thick film resistor in a 2512 package. Finding a direct replacement requires matching its tight tolerance, while several functional alternatives with wider tolerance exist.

AI replacement insight

Electrical riskmedium

Tolerance downgrade from 1% to 5% requires circuit analysis.

Package risklow

2512 is a standard package with good compatibility.

Can it be replaced directly?

No direct, 1-to-1 replacement with identical parameters was found in this batch. All viable options involve a parametric relaxation, primarily in resistance tolerance.

Best replacement path

Use a parametric alternative from the same series, like RC2512JK-7W100KL, if the application can tolerate a ±5% resistance variance.

Main risk

The primary risk is substituting a 1% precision resistor with a 5% tolerance part, which can impact the accuracy and stability of sensitive analog circuits.

Recommended alternatives

A form-fit compatible resistor from the same Yageo series with a wider tolerance of ±5%.
