ECQ-P1H471JZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H471JZ is a 470 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±5% tolerance. This radial through-hole component utilizes polypropylene (PP) dielectric material and is designed for high-frequency and switching applications. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H471JZ is determined by the following critical parameters:

• Capacitance Value: 470 pF (exact match required)
• Tolerance: ±5% (acceptable range for equivalent functionality)
• Voltage Rating (DC): Minimum 50V (equal or higher ratings are acceptable)
• Dielectric Material: Film-based capacitor technology (polypropylene or equivalent film dielectric)

The ECH-U1H471JX5 qualifies as a functional equivalent based on matching capacitance, tolerance, and voltage rating specifications. However, this substitute introduces a change in mounting technology from through-hole radial to surface-mount 0805 format, which requires circuit board redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H471JX5 provides electrical equivalence in capacitance, tolerance, and DC voltage rating. The substitute part carries Active product status and ROHS3 compliance, offering improved regulatory alignment compared to the obsolete ECQ-P1H471JZ.

Selection of the ECH-U1H471JX5 requires evaluation of the following factors:

• Mounting Technology Change: Transition from through-hole radial to surface-mount 0805 format necessitates circuit board layout redesign and assembly process modification.
• Dielectric Material Difference: Substitution introduces polyphenylene sulfide (PPS) metallized-stacked dielectric in place of polypropylene (PP), which may affect frequency response and ESR characteristics in high-frequency applications.
• Temperature Range Expansion: The substitute part supports -55°C ~ 125°C operation, exceeding the original -40°C ~ 85°C range.
• Regulatory Compliance: ROHS3 compliance of the substitute part aligns with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H471JX5 be used as a direct replacement for the ECQ-P1H471JZ?

A: Electrical substitution is possible based on matching capacitance (470 pF), tolerance (±5%), and DC voltage rating (50V). However, the mounting technology differs fundamentally: the ECQ-P1H471JZ is through-hole radial, while the ECH-U1H471JX5 is surface-mount 0805. Direct board-level substitution without redesign is not feasible.

Q: What are the key differences between these two parts?

A: Primary differences include mounting type (through-hole vs. surface-mount), package format (radial vs. 0805), dielectric material (polypropylene vs. polyphenylene sulfide), and operating temperature range (-40°C ~ 85°C vs. -55°C ~ 125°C). The substitute part is currently in active production status.

Q: Are there any compliance or regulatory differences?

A: The ECH-U1H471JX5 is ROHS3 compliant with MSL 1 rating, while the ECQ-P1H471JZ carries no specified RoHS status and has MSL not applicable. Both parts share the same ECCN (EAR99) and HTSUS classification.

Q: Does the dielectric material change affect circuit performance?

A: Dielectric material substitution from polypropylene to polyphenylene sulfide may introduce differences in frequency response, dissipation factor, and equivalent series resistance (ESR). Application-specific evaluation is required for high-frequency and switching circuits.

Q: What is the inventory status of these parts?

A: The ECQ-P1H471JZ has 861 pieces in stock as new original inventory. The ECH-U1H471JX5 has 16,604 pieces available, reflecting its active production status.
