ECQ-P1H154GZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H154GZ is a 0.15 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 maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H154GZ requires matching the following critical electrical parameters: capacitance value (0.15 µF), 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 ECH-U1H154GX9 shares the identical capacitance, tolerance, and voltage rating specifications. However, this substitute introduces differences in dielectric material (Polyphenylene Sulfide with metallization versus polypropylene), mounting type (surface mount versus through-hole), and operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C). These differences must be evaluated against specific circuit requirements before implementation.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H154GX9 is an active product with ROHS3 compliance, addressing the obsolescence status of the ECQ-P1H154GZ. Both components share identical electrical specifications for capacitance, tolerance, and DC voltage rating, establishing functional equivalence at the circuit level.

Selection of the ECH-U1H154GX9 requires PCB redesign due to the transition from through-hole radial mounting to surface-mount 2416 package configuration. The extended operating temperature range (-55°C ~ 125°C) provides broader environmental coverage compared to the original part. The change in dielectric material from polypropylene to metallized polyphenylene sulfide affects frequency response characteristics and should be evaluated against application-specific performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H154GX9 be used as a direct pin-for-pin replacement for the ECQ-P1H154GZ?

A: No. The ECQ-P1H154GZ uses through-hole radial termination with 0.394" lead spacing, while the ECH-U1H154GX9 is a surface-mount component with solder pads. PCB layout modification is required.

Q: Are the electrical specifications identical between these two parts?

A: Capacitance (0.15 µF), tolerance (±2%), and DC voltage rating (50V) are identical. The ECH-U1H154GX9 includes a 30V AC rating not specified for the original part. Dielectric materials differ, which may affect frequency response and ESR characteristics.

Q: What is the impact of the different operating temperature ranges?

A: The ECQ-P1H154GZ operates from -40°C to 85°C, while the ECH-U1H154GX9 operates from -55°C to 125°C. The substitute provides extended low-temperature and high-temperature capability. Applications limited to the original temperature range will function within the substitute's specifications.

Q: Does the change from polypropylene to polyphenylene sulfide dielectric affect circuit performance?

A: Dielectric material differences influence frequency response, dissipation factor, and ESR. Circuit-specific performance validation is necessary to confirm functional equivalence in high-frequency and switching applications.

Q: Is the ECH-U1H154GX9 compliant with current regulatory standards?

A: Yes. The ECH-U1H154GX9 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The ECQ-P1H154GZ compliance status is not specified in available documentation.
