ECQ-P1H224GZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H224GZ is a 0.22 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 part is currently obsolete, making equivalent substitutes necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H224GZ is determined by the following critical parameters:

• Capacitance Value: 0.22 µF (exact match required)
• Tolerance: ±2% (exact match required)
• Voltage Rating - DC: 50V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Film-based construction (polypropylene or equivalent film technology)
• Operating Temperature Range: Must support the application's thermal requirements
• Mounting Type: Surface mount alternatives acceptable if circuit board layout permits redesign

The ECH-U1H224GX9 qualifies as a substitute based on matching capacitance, tolerance, and DC voltage rating. However, this part represents a different mounting technology (surface mount 2416 package) and dielectric material (polyphenylene sulfide with metallized-stacked construction) compared to the original radial through-hole design.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H224GX9 is an active product with current manufacturing support and ROHS3 compliance, providing long-term availability advantages over the obsolete ECQ-P1H224GZ. The substitute maintains electrical equivalence in capacitance, tolerance, and DC voltage rating.

Selection of the ECH-U1H224GX9 requires circuit board redesign due to the transition from through-hole radial mounting to surface-mount 2416 package technology. The substitute offers an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C), which may provide additional thermal margin in applications requiring broader temperature performance.

The dielectric material difference (polypropylene versus polyphenylene sulfide with metallized-stacked construction) represents a change in capacitor technology. Both materials are film-based and suitable for high-frequency applications, though specific performance characteristics in switching applications should be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H224GX9 be used as a direct replacement for the ECQ-P1H224GZ without circuit board modification?

A: No. The ECQ-P1H224GZ is a through-hole radial component, while the ECH-U1H224GX9 is a surface-mount 2416 package. Direct substitution requires circuit board redesign and component footprint changes.

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

A: The capacitance (0.22 µF), tolerance (±2%), and DC voltage rating (50V) are identical. The dielectric materials differ: polypropylene (PP) in the original part versus polyphenylene sulfide (PPS) with metallized-stacked construction in the substitute. Both are film-based technologies suitable for high-frequency applications.

Q: What is the significance of the extended operating temperature range in the ECH-U1H224GX9?

A: The substitute supports -55°C ~ 125°C compared to the original -40°C ~ 85°C. This extended range provides additional thermal margin for applications operating at temperature extremes, though it does not affect electrical performance within the original part's temperature specification.

Q: Does the ECH-U1H224GX9 meet RoHS compliance requirements?

A: Yes, the ECH-U1H224GX9 is ROHS3 compliant. The original ECQ-P1H224GZ does not specify RoHS status in the provided data.

Q: What packaging format is the ECH-U1H224GX9 supplied in?

A: The ECH-U1H224GX9 is supplied in Tape & Reel (TR) format, standard for surface-mount components. The original ECQ-P1H224GZ is a through-hole component without specified packaging format.
