Is there a pin-compatible replacement for ERH2GM101M25OT?

Yes, AISHI EWH2GM101M25OT shares the same 18x25mm package, pin spacing, and primary electrical ratings. However, its endurance is lower, which must be verified for your application's reliability needs.

What risks should I check before replacing ERH2GM101M25OT?

Key risks include package dimension mismatches (diameter, length), which affect board fit, and differences in endurance/lifetime, which impact reliability. Also verify ripple current and ESR if critical for your design.

ERH2GM101M25OT Alternatives, Datasheet & Cross Reference | AISHI

Finding a substitute for the AISHI ERH2GM101M25OT, a 100µF 400V aluminum electrolytic capacitor, requires checking package size (18x25mm), endurance (3000h), and key electricals. Several alternatives exist with varying trade-offs.

AI replacement insight

Package riskhigh

Most alternatives have different dimensions, requiring PCB layout review.

Electrical riskmedium

Key risks are lower endurance or different ESR. Some candidates have incorrect capacitance.

Can it be replaced directly?

No perfect direct replacement is identified. The closest candidate, EWH2GM101M25OT, is a downgrade in endurance.

Best replacement path

For a drop-in fit, consider AISHI EWH2GM101M25OT but validate the lower 2000hr endurance. For better performance, a functional alternative like Rubycon 400CXW100MEFR16X31.5 requires a layout check.

Main risk

The main risks are physical package mismatches with most alternatives and a reliability downgrade (lower endurance) with the only pin-compatible option.

Recommended alternatives

Physically identical with matching key electricals, but has a lower endurance rating.
