Is there a pin-compatible replacement for PE102J2A0502?

Several parts have the same 5mm lead pitch, making them physically compatible. However, no verified pin-to-pin replacement exists due to differences in temperature ratings.

What risks should I check before replacing PE102J2A0502?

Verify your circuit's maximum operating temperature, as many alternatives are rated for +85°C, not the original's +110°C. Also confirm the physical dimensions of the capacitor case.

PE102J2A0502 Alternatives, Datasheet & Cross Reference | KYET

PE102J2A0502 is a 1nF 100V ±5% metallized polyester film capacitor with a 5mm lead pitch. Finding a substitute requires matching these key parameters and the +110°C temperature rating.

AI replacement insight

Electrical riskhigh

Using a part with a lower temperature rating can lead to premature failure.

Package risklow

The 5mm radial lead pitch is a common standard.

Can it be replaced directly?

No direct drop-in replacement has been verified. Several candidates match form and electricals but have a lower temperature rating of +85°C, requiring engineering review.

Best replacement path

Search for 1nF, 100V, ±5% film capacitors with a 5mm lead pitch and a temperature rating of at least -40°C to +110°C.

Main risk

The primary risk is the lower maximum operating temperature of available alternatives, which may cause failure in high-temperature environments.

Recommended alternatives

Very similar part from the same manufacturer, but with a lower temperature rating.
