ECQ-P1H682GZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H682GZ is a 6800 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±2% tolerance. This radial through-hole component utilizes polypropylene (PP) dielectric material and is designed for high-frequency and switching applications. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H682GZ requires matching of critical electrical parameters: capacitance value (6800 pF), tolerance (±2%), and voltage rating (50V DC minimum). The dielectric material, operating temperature range, and mounting configuration are secondary considerations that may vary based on application requirements and PCB layout constraints.

The identified substitute, ECH-U1H682GX5, maintains electrical equivalence through identical capacitance, tolerance, and voltage rating specifications. However, this substitute introduces a change in mounting technology from through-hole radial to surface-mount 1206 package format, which requires PCB redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H682GX5 provides electrical equivalence to the obsolete ECQ-P1H682GZ through matching capacitance, tolerance, and DC voltage specifications. The substitute maintains active product status and carries ROHS3 compliance certification, supporting regulatory requirements for new designs.

Selection of the ECH-U1H682GX5 requires evaluation of mounting technology compatibility. The transition from through-hole radial to surface-mount 1206 package necessitates PCB layout modification and assembly process adjustment. The extended operating temperature range (-55°C to 125°C) of the substitute provides broader thermal performance compared to the original part (-40°C to 85°C). The dielectric material change from polypropylene to polyphenylene sulfide (PPS) metallized-stacked construction may affect frequency response characteristics in high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H682GX5 be used as a direct replacement for the ECQ-P1H682GZ?

A: Electrical substitution is possible due to matching capacitance (6800 pF), tolerance (±2%), and DC voltage rating (50V). However, physical substitution requires PCB redesign because the substitute uses surface-mount 1206 packaging instead of through-hole radial configuration.

Q: What are the critical parameters for substitution?

A: Capacitance value, tolerance, and voltage rating are the primary electrical criteria. The ECH-U1H682GX5 matches all three specifications. Dielectric material, operating temperature range, and package type are secondary parameters that may require application-specific evaluation.

Q: Does the dielectric material change affect performance?

A: The original part uses polypropylene (PP) dielectric, while the substitute uses polyphenylene sulfide (PPS) metallized-stacked construction. Both materials support the specified electrical ratings. Application-specific performance differences depend on frequency response requirements and environmental conditions.

Q: What is the impact of the extended temperature range?

A: The substitute operates from -55°C to 125°C compared to the original -40°C to 85°C range. This provides broader thermal capability and may be advantageous in demanding thermal environments, though it is not required for applications within the original temperature specification.

Q: Are there packaging considerations for assembly?

A: Yes. The original part is through-hole radial (0.335" L x 0.197" W, 13.00mm height), while the substitute is surface-mount 1206 (0.126" L x 0.063" W, 1.10mm height). Assembly process, PCB footprint design, and soldering methods differ significantly between these package types.

Q: What compliance certifications apply to the substitute?

A: The ECH-U1H682GX5 is ROHS3 compliant and carries Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
