Is there a pin-compatible replacement for ERS1CM101D11OT?

Yes, parts like the Rubycon 25YXJ100MFFC5X11 share the same 5x11mm radial package and pin count, making them potential pin-compatible replacements. Always confirm lead spacing and secondary electricals from the datasheet.

What risks should I check before replacing ERS1CM101D11OT?

Key risks include: 1) Package mismatch if not using a 5x11mm radial part. 2) Electrical mismatch in ESR and ripple current, which can affect circuit stability and component lifetime. 3) A lower voltage rating, which is unsafe.

Package risklow

For candidates with matching 5x11mm radial packages.

Electrical riskmedium

ESR and ripple current are often unspecified for the target and must be verified against the application's needs.

Can it be replaced directly?

Yes, the Rubycon 25YXJ100MFFC5X11 is a potential pin-compatible replacement with an upgraded 25V rating. However, you must confirm that its ESR (400mΩ) and ripple current (250mA) meet your circuit's requirements.

Best replacement path

The Rubycon 25YXJ100MFFC5X11 is a strong candidate, offering the same package and a higher voltage rating. Verification of ESR and ripple current is recommended.

Main risk

The primary risk is mismatch in secondary electrical parameters like ESR and ripple current, which are critical for performance and reliability in many circuits.
