Is there a pin-compatible replacement for MFR50SFTE52-100R?

No pin-compatible replacement has been fully verified. While several candidates have the same axial lead format, their higher power ratings mean they are likely physically larger. You must check the datasheet dimensions to confirm fit before ordering.

What risks should I check before replacing MFR50SFTE52-100R?

The main risk is physical incompatibility. A substitute with a higher power rating will be larger and may not fit in the space allocated on your circuit board. Also, check the Temperature Coefficient of Resistance (TCR) to ensure it meets your design's stability requirements.

MFR50SFTE52-100R Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo MFR50SFTE52-100R, a 100Ω 0.5W 1% resistor, involves balancing electrical upgrades with physical constraints. While several alternatives offer higher power ratings, verifying their dimensions is critical for a successful replacement.

AI replacement insight

Package riskmedium

Candidates have higher power ratings (1W-3W vs 0.5W), implying larger body sizes that may not fit.

Electrical risklow

Most candidates meet or exceed key electrical specs like power and TCR, but verification is still needed.

Sourcing risklow

100Ω 1% resistors are common, but finding one with the exact 0.5W power rating and size may require checking multiple vendors.

Can it be replaced directly?

No direct, verified drop-in replacement has been identified. All candidates have higher power ratings, which likely means they are physically larger than the original part.

Best replacement path

Find an axial metal film resistor with 100Ω resistance, ±1% tolerance, a power rating of 0.5W or higher, and matching physical dimensions.

Main risk

The primary risk is physical incompatibility. Higher power resistors are larger and may not fit on the PCB.

Recommended alternatives

This UNI ROYAL resistor is an upgrade with higher power (1W) and better TCR (±50ppm/°C).
