Is there a pin-compatible replacement for FRL2512FR620TS?

Yes, several resistors in the same 2512 package are available. Candidates like 25121WF680LT4E share the same package and pinout, but electrical parameters like resistance (0.68Ω vs 0.62Ω) and TCR must be verified for your circuit.

What risks should I check before replacing FRL2512FR620TS?

Key risks include: 1) Resistance Mismatch: Ensure the ~10% higher resistance of alternatives is acceptable. 2) TCR: Verify the temperature coefficient of the replacement meets your design's stability needs. 3) Power Derating: Ensure the power rating provides sufficient margin.

Finding a substitute for the FRL2512FR620TS, a 0.62Ω 1W 1% resistor in a 2512 package, involves balancing resistance value, power rating, and temperature coefficient (TCR). Alternatives may offer higher power or better TCR but require careful validation.

AI replacement insight

Electrical riskmedium

Resistance and TCR differences require validation.

Package risklow

All viable candidates use the same 2512 package.

Sourcing risklow

Multiple vendors produce similar 2512 low-ohm resistors.

Can it be replaced directly?

No direct, identical replacement for FRL2512FR620TS was found. The closest options have a resistance of 0.68Ω, requiring engineering review.

Best replacement path

Parametric alternatives with slightly higher resistance (0.68Ω) but potential upgrades in power or TCR are available. Direct drop-in with identical resistance is not found in this batch.

Main risk

The primary risk is the resistance deviation (~+10%), which could affect circuit performance, especially in precision current sensing or feedback loops.

Recommended alternatives

A 2512 chip resistor with the same power and tolerance, but slightly higher resistance (0.68Ω vs 0.62Ω).
