Is there a pin-compatible replacement for PE104J2A0501?

Currently, no pin-compatible (5mm lead pitch) replacements with matching key electrical parameters have been identified in this review. All functional alternatives require physical adaptation.

What risks should I check before replacing PE104J2A0501?

Key risks include: 1) Package mismatch, primarily lead pitch (target is 5mm). 2) Weaker tolerance (±10% vs ±5%). 3) Different dielectric material (polypropylene vs. polyester), which affects temperature stability and other AC characteristics.

PE104J2A0501 Alternatives, Datasheet & Cross Reference | KYET

PE104J2A0501 is a 100nF 100V ±5% polyester film capacitor with a 5mm lead pitch. Finding a direct replacement requires matching these key parameters, especially the physical package and tolerance.

AI replacement insight

Package riskhigh

All candidates have a different lead pitch (7.5mm, 10mm, or 15mm) vs the target's 5mm.

Electrical riskmedium

Candidates have weaker tolerance (±10% vs ±5%) and different dielectric material, which can affect performance.

Can it be replaced directly?

No direct, drop-in replacement for PE104J2A0501 has been confirmed. All candidates require design review due to significant physical and parametric differences.

Best replacement path

Search for a 100nF, 100V or higher, ±5% tolerance polyester or polypropylene film capacitor in a radial package with 5mm lead spacing.

Main risk

The primary risk is physical incompatibility. No candidates match the target's 5mm lead spacing, requiring board modification.

Recommended alternatives

Functional alternative with different package (10mm pitch), weaker tolerance (±10%), and higher voltage rating.
