ECQ-P1H273GZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H273GZ is a 0.027 µF 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 product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support, maintenance, and repair operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H273GZ is determined by the following critical parameters:

• Capacitance Value: 0.027 µF (exact match required)
• Tolerance: ±2% (acceptable range for circuit function)
• Voltage Rating - DC: 50V minimum (equal or higher acceptable)
• Dielectric Material: Film-based capacitor (polypropylene or equivalent film technology)
• Operating Temperature Range: Must support application requirements
• Mounting Compatibility: Physical form factor and board integration method

The ECH-U1H273GX5 qualifies as a functional substitute based on matching capacitance value (0.027 µF), tolerance (±2%), and DC voltage rating (50V). However, this substitute introduces a change in mounting technology from through-hole radial to surface-mount 1210 package format, which requires PCB redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H273GX5 provides electrical equivalence in capacitance, tolerance, and DC voltage rating. The substitute part carries Active product status and ROHS3 compliance, supporting long-term availability and regulatory requirements.

Selection of this substitute requires evaluation of mounting technology compatibility. The transition from through-hole radial to surface-mount 1210 package necessitates PCB layout modification and assembly process changes. The extended operating temperature range (-55°C ~ 125°C) of the substitute exceeds the original specification (-40°C ~ 85°C), providing enhanced thermal performance margin.

The dielectric material change from polypropylene (PP) to polyphenylene sulfide (PPS) metallized-stacked construction represents a functional film capacitor technology transition. Both materials are suitable for high-frequency and switching applications within the specified voltage and capacitance parameters.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H273GX5 be used as a direct replacement for the ECQ-P1H273GZ?

A: Electrical substitution is valid based on matching capacitance (0.027 µF), tolerance (±2%), and DC voltage rating (50V). Physical substitution requires PCB redesign due to mounting type change from through-hole radial to surface-mount 1210 package.

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

A: Primary differences include mounting technology (through-hole vs. surface-mount), package format (radial vs. 1210), dielectric material (polypropylene vs. polyphenylene sulfide metallized-stacked), and operating temperature range (-40°C ~ 85°C vs. -55°C ~ 125°C).

Q: Is the dielectric material change from PP to PPS significant?

A: Both polypropylene and polyphenylene sulfide are film-based dielectric materials suitable for high-frequency and switching applications. The PPS metallized-stacked construction in the substitute provides equivalent electrical performance within the specified parameters.

Q: What is the inventory status of these parts?

A: The ECQ-P1H273GZ (obsolete) has 927 pcs in stock. The ECH-U1H273GX5 (active) has 10,809 pcs in stock, providing superior long-term availability.

Q: Does the substitute part meet current compliance standards?

A: The ECH-U1H273GX5 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original ECQ-P1H273GZ compliance status is not specified in available documentation.
