ECQ-P1H562GZ Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECQ-P1H562GZ is a 5600 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 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 eligibility for the ECQ-P1H562GZ is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 5600 pF (exact match required)
• Voltage rating: Minimum 50V DC
• Tolerance: ±2% to ±10% acceptable range
• Dielectric material: Film-based (polypropylene, polyester, or polyphenylene sulfide)
• Mounting compatibility: Through-hole radial or surface-mount alternatives

Secondary Compatibility Factors:

• Operating temperature range: Minimum -40°C to 85°C
• Termination type: PC pins (through-hole) or solder pads (surface-mount)
• Lead spacing: 0.197" (5.00mm) for direct pin-compatible replacement

Three substitute parts meet the core electrical requirements while offering varying trade-offs in packaging, dielectric material, and compliance status.

Parameter Comparison

Engineering Selection Recommendations

ECH-U1H562GX5 (Panasonic): This substitute offers active product status and ROHS3 compliance. The surface-mount 1206 package requires PCB layout modification and represents a technology transition from through-hole to SMD. The extended operating temperature range (-55°C to 125°C) exceeds the original specification. Dielectric material differs (PPS vs. polypropylene), which may affect high-frequency performance characteristics. Suitable for new designs or redesigns accommodating SMD assembly.

185562K100RAA-F (Cornell Dubilier Electronics): This through-hole radial alternative maintains mechanical compatibility with identical lead spacing (0.197"). Voltage rating is elevated to 100V DC, providing additional safety margin. ROHS3 compliance and active product status ensure long-term availability. Tolerance is ±10% versus the original ±2%, which may impact precision-critical applications. Polyester dielectric differs from polypropylene. Recommended for direct pin-compatible replacement in existing through-hole designs.

QYX1H562JTP (Nichicon): This through-hole radial option provides mechanical compatibility and matches the original operating temperature range. Product status is obsolete, limiting long-term supply assurance. ROHS3 compliance is confirmed. Tolerance is ±5%, representing a middle ground between the original ±2% and the CDE alternative. Polyester dielectric differs from polypropylene. Suitable as an interim solution where through-hole compatibility is mandatory and supply of the original part is exhausted.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1H562GX5 be used as a direct replacement for ECQ-P1H562GZ?

A: Electrical substitution is valid (same capacitance, tolerance, and voltage rating). However, mounting type differs fundamentally: ECH-U1H562GX5 is surface-mount (1206 package) while ECQ-P1H562GZ is through-hole radial. Direct PCB mounting without redesign is not possible. Dielectric material also differs (PPS vs. polypropylene), which may affect frequency response in high-frequency applications.

Q: What is the impact of tolerance differences between the main part and substitutes?

A: ECQ-P1H562GZ specifies ±2% tolerance. The 185562K100RAA-F substitute has ±10% tolerance, resulting in a capacitance range of 5040 pF to 6160 pF versus the original 5488 pF to 5712 pF. Applications requiring tight capacitance control (precision filters, timing circuits) may experience performance degradation. The QYX1H562JTP with ±5% tolerance offers a compromise.

Q: Are there compliance or supply chain advantages to selecting one substitute over others?

A: ECH-U1H562GX5 and 185562K100RAA-F both carry active product status and ROHS3 compliance, ensuring regulatory alignment and long-term availability. QYX1H562JTP is obsolete, presenting supply risk similar to the original part. For new production or long-term designs, active-status parts are preferred.

Q: How does dielectric material affect performance?

A: Polypropylene (original) offers superior high-frequency performance and lower dissipation factor compared to polyester or PPS alternatives. Applications in switching circuits or high-frequency filtering may exhibit different transient response with polyester or PPS dielectrics. Polyphenylene sulfide (ECH-U1H562GX5) provides extended temperature stability but differs in frequency characteristics.

Q: What are the mechanical constraints for each substitute?

A: ECQ-P1H562GZ and both through-hole alternatives (185562K100RAA-F, QYX1H562JTP) share radial package geometry with 0.197" lead spacing, enabling direct PCB hole compatibility. ECH-U1H562GX5 requires SMD footprint (1206/3216 metric), necessitating PCB redesign. Physical dimensions vary: ECQ-P1H562GZ is 8.50mm L × 4.50mm W; 185562K100RAA-F is 7.20mm L × 2.50mm W; QYX1H562JTP is 6.00mm L × 3.00mm W.
