ECQ-P1H102GZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H102GZ is a 1000 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±2% tolerance. This radial through-hole component utilizes polypropylene dielectric material and is designed for high-frequency and switching applications. The product is currently obsolete, making equivalent or substitute parts necessary for ongoing system support and new designs requiring similar electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECQ-P1H102GZ is evaluated based on the following critical parameters: capacitance value (1000 pF), tolerance (±2%), voltage rating (50V DC minimum), and dielectric material compatibility. The mounting type and package configuration determine physical and electrical interchangeability within the circuit design.

Two substitute parts are identified:

ECH-U1H102GX5 – Surface mount alternative with equivalent capacitance and tolerance but different mounting technology (0805 SMD vs. radial through-hole). Suitable only for designs permitting surface-mount conversion.

ECW-H12102JV – Through-hole radial alternative with equivalent capacitance and mounting type. Voltage rating (1250V DC) exceeds the original specification, and tolerance is ±5% rather than ±2%. Lead spacing differs significantly (0.591" vs. 0.197").

Parameter Comparison

Engineering Selection Recommendations

ECH-U1H102GX5 is suitable for new designs or redesigns where surface-mount technology is acceptable. This part is active in production with ROHS3 compliance and REACH unaffected status. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin compared to the original specification.

ECW-H12102JV maintains through-hole radial configuration compatible with existing PCB layouts designed for the ECQ-P1H102GZ. This part is active in production with ROHS3 compliance. The higher voltage rating (1250V DC) provides design margin for overvoltage conditions. However, the ±5% tolerance is less precise than the original ±2%, and the larger lead spacing (0.591" vs. 0.197") requires PCB layout verification before implementation.

For direct replacement in existing through-hole designs with minimal PCB modification, ECW-H12102JV is the primary candidate. For new designs permitting surface-mount technology, ECH-U1H102GX5 offers superior thermal performance and active production status.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1H102GX5 be used as a direct replacement for ECQ-P1H102GZ?

A: No. ECH-U1H102GX5 is a surface-mount component (0805 package) while ECQ-P1H102GZ is through-hole radial. Direct PCB substitution is not possible without redesign. However, the electrical parameters (1000 pF, ±2%, 50V DC) are equivalent.

Q: What is the impact of the ±5% tolerance in ECW-H12102JV compared to the ±2% original specification?

A: The tolerance difference affects circuit performance in applications requiring precise capacitance values. For high-frequency filtering or timing circuits, the ±5% tolerance may introduce measurable frequency or timing shifts. Verify circuit tolerance requirements before selection.

Q: Does the larger lead spacing of ECW-H12102JV (0.591" vs. 0.197") affect compatibility?

A: Yes. The lead spacing determines PCB hole pattern compatibility. ECW-H12102JV requires a different PCB footprint and cannot be installed in the original ECQ-P1H102GZ hole pattern without modification.

Q: Are both substitute parts RoHS compliant?

A: Yes. ECH-U1H102GX5 and ECW-H12102JV are both ROHS3 compliant. ECW-H12102JV also carries REACH unaffected status.

Q: Which substitute part has better availability?

A: ECH-U1H102GX5 has significantly higher inventory (58,124 pcs) compared to ECW-H12102JV (1,038 pcs), indicating better long-term availability for high-volume applications.
