What risks should I check before replacing MPE105J100V82CL0042?

When replacing this part, first verify the package and lead pitch (7.5mm) for a physical fit. Second, ensure the replacement has at least a 100V rating, 1uF capacitance, and a tolerance of ±5% or better. Also check the dielectric type and temperature range.

MPE105J100V82CL0042 Alternatives, Datasheet & Cross Reference | KNSCHA

Finding a substitute for the KNSCHA MPE105J100V82CL0042, a 1uF 100V 5% radial film capacitor, requires matching the 7.5mm lead pitch for a drop-in fit. Alternatives exist with similar electricals but may have different physical dimensions.

AI replacement insight

Package riskhigh

Many candidates have different lead spacing or are SMD.

Electrical risklow

Key parameters are common, but tolerance and dielectric type must be matched.

Can it be replaced directly?

Direct replacement for MPE105J100V82CL0042 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The best replacement path is to find a 1uF, 100V (or higher), ±5% film capacitor in a radial package with a 7.5mm lead pitch, such as the KYET PE105J2A0701.

Main risk

The main risk is package incompatibility. Many alternatives have different lead pitches (e.g., 5mm or 22.5mm) or are surface-mount (SMD), which are not drop-in replacements.

Recommended alternatives

A potential pin-compatible replacement with matching package, capacitance, voltage, and tolerance.
