Is there a pin-compatible replacement for PE474J2A0502?

Currently, no pin-compatible (5mm lead pitch) replacements with matching key electrical parameters have been identified. All reviewed candidates have a larger lead pitch, preventing direct substitution.

What risks should I check before replacing PE474J2A0502?

Key risks include: 1) Package Mismatch: Ensure the substitute's lead pitch fits your PCB layout. 2) Dielectric Difference: The target is polyester; substitutes may be polypropylene, affecting frequency response and temperature characteristics. 3) Tolerance: Some alternatives have a wider tolerance (±10% vs ±5%).

AI replacement insight

Package riskhigh

All candidates have a different lead pitch (10mm to 27mm) vs the target's 5mm.

Electrical riskmedium

Most candidates have a different dielectric (Polypropylene vs Polyester) and weaker tolerance.

Can it be replaced directly?

No direct, drop-in replacement for PE474J2A0502 is currently available among the candidates. All options require mechanical and electrical review.

Best replacement path

Search for a 0.47µF, 100V (or higher), ±5% film capacitor in a radial package with 5mm lead pitch. Prioritize polyester (PET) dielectric, but polypropylene (PP) may be acceptable if application performance is verified.

Main risk

The primary risk is the physical package mismatch, as no candidates share the target's 5mm lead pitch, making them incompatible without PCB modification.

Recommended alternatives

Functional alternative with same capacitance but requires review for different package, tolerance, and application type.
