What risks should I check before replacing PE105J2A0701?

Key risks include mismatched package or lead pitch requiring board changes, lower voltage ratings causing failure, wider tolerance affecting circuit performance, and different dielectric materials (e.g., electrolytic vs. film) impacting ESR and lifetime.

PE105J2A0701 Alternatives, Datasheet & Cross Reference | KYET

Finding a substitute for the KYET PE105J2A0701, a 1uF 100V 5% radial film capacitor, involves matching capacitance, voltage, tolerance, and the 7.5mm lead pitch. Several options exist with varying degrees of compatibility.

AI replacement insight

Package riskhigh

Many alternates have different packages (SMD) or lead spacing, requiring board redesign.

Electrical riskhigh

Some candidates have lower voltage ratings or wider tolerance, which can cause failure or performance issues.

Can it be replaced directly?

Direct replacement for PE105J2A0701 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most direct path is MPE105J100V82CL0042, which matches key form, fit, and function parameters.

Main risk

The main risk is using a part with an incompatible package (SMD or different lead pitch) or a lower voltage rating.

Recommended alternatives

Offers identical capacitance, tolerance, and package with a 7.5mm lead pitch.
