Is there a pin-compatible replacement for MFR-25FBF52-1M?

Several axial resistors are pin-compatible, but may have different physical sizes or electrical parameters. The CCO MF2WS-1MΩ±1% T is a candidate, but requires size verification before considering it a drop-in replacement.

What risks should I check before replacing MFR-25FBF52-1M?

Key risks are physical size (alternatives may be larger), Temperature Coefficient (TCR) for stability, and tolerance. Always verify datasheet dimensions and electrical specs against your application's needs.

AI replacement insight

Package riskmedium

Alternatives are often physically larger due to higher power ratings.

Electrical riskmedium

Some candidates have worse TCR, affecting stability over temperature.

Sourcing risklow

Axial 1MΩ 1% resistors are widely available from multiple vendors.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. The CCO MF2WS-1MΩ±1% T is a strong candidate, but its larger 2W body size must be verified.

Best replacement path

The best path is an upgrade to a higher-power metal film resistor like the CCO MF2WS series, provided physical dimensions are compatible with the PCB.

Main risk

The main risk is physical incompatibility due to larger body sizes of higher-power alternatives. For precision circuits, a worse TCR is also a key risk.

Recommended alternatives

An axial metal film resistor with matching resistance and tolerance, but a significantly higher 2W power rating.
