ECQ-P1H124GZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H124GZ is a 0.12 µF film capacitor rated at 50V DC with ±2% tolerance, manufactured by Panasonic Electronic Components. This radial through-hole component uses polypropylene (PP) dielectric material and is designed for high-frequency and switching applications. The part is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H124GZ is determined by the following critical parameters:

• Capacitance Value: 0.12 µF (exact match required)
• Voltage Rating - DC: Minimum 50V (equal or higher acceptable)
• Tolerance: ±2% (matching tolerance class)
• Dielectric Material: Film-based construction (polypropylene or equivalent film technology)
• Operating Temperature Range: Must support minimum -40°C ~ 85°C
• Mounting Compatibility: Physical form factor and termination type must accommodate existing PCB layouts

The ECH-U1H124GX9 meets the capacitance, voltage, and tolerance requirements. However, this substitute employs surface-mount technology (2416 package) with solder pad termination, representing a different mounting category from the original through-hole radial design. Substitution requires PCB redesign or adapter solutions.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H124GX9 satisfies the core electrical requirements of the ECQ-P1H124GZ: identical capacitance (0.12 µF), tolerance (±2%), and DC voltage rating (50V). The substitute offers extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and active product status with ROHS3 compliance.

The primary constraint is mounting technology. The ECQ-P1H124GZ is a through-hole radial component with PC pin termination, while the ECH-U1H124GX9 is a surface-mount device with solder pad termination in 2416 package format. Direct board-level substitution is not feasible without PCB redesign or mechanical adaptation.

Dielectric material differs: the original uses polypropylene (PP), while the substitute employs polyphenylene sulfide (PPS) with metallized-stacked construction. Both are film-based technologies suitable for the specified applications.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H124GX9 replace the ECQ-P1H124GZ directly on existing PCBs?

A: No. The ECQ-P1H124GZ uses through-hole radial mounting with PC pin termination, while the ECH-U1H124GX9 is a surface-mount component with solder pad termination. Direct substitution requires PCB redesign or mechanical adapter solutions.

Q: Are the electrical specifications compatible?

A: Yes. Both components share identical capacitance (0.12 µF), tolerance (±2%), and DC voltage rating (50V). The substitute's extended temperature range (-55°C ~ 125°C) exceeds the original specification.

Q: What is the difference in dielectric material between these parts?

A: The ECQ-P1H124GZ uses polypropylene (PP) dielectric. The ECH-U1H124GX9 uses polyphenylene sulfide (PPS) with metallized-stacked construction. Both are film-based technologies appropriate for high-frequency and switching applications.

Q: Does the ECH-U1H124GX9 meet current compliance standards?

A: Yes. The ECH-U1H124GX9 is ROHS3 compliant and REACH unaffected, with active product status. The ECQ-P1H124GZ is obsolete.

Q: What are the physical size differences?

A: The ECQ-P1H124GZ measures 17.00mm L x 8.50mm W with 20.50mm seated height. The ECH-U1H124GX9 measures 6.00mm L x 4.10mm W with 2.10mm seated height. The substitute is significantly smaller due to surface-mount construction.

Q: Are there inventory considerations?

A: The ECQ-P1H124GZ has 832 pieces in stock (obsolete status). The ECH-U1H124GX9 has 9735 pieces available in active production, providing greater supply continuity.
