ECH-S1H223JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H223JZ is a 0.022 µF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±5% tolerance. This radial through-hole component utilizes polyphenylene sulfide (PPS) dielectric material and is designed for high-frequency and switching applications. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H223JZ is based on the following critical parameters:

• Capacitance Value: Must be 0.022 µF (exact match required)
• Voltage Rating: Must meet or exceed 50V DC
• Dielectric Material: Polyphenylene sulfide (PPS) or equivalent film material
• Operating Temperature: Must support the required thermal range
• Physical Compatibility: Mounting type and lead configuration must accommodate the application circuit

The ECH-U1H223GX5 meets the capacitance and voltage requirements with improved tolerance (±2%) and extended temperature range. However, this substitute transitions from radial through-hole to surface-mount 1210 package, requiring circuit board redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H223GX5 is the active equivalent for the obsolete ECH-S1H223JZ based on matching capacitance, voltage rating, and dielectric material. The substitute offers improved tolerance specification (±2% versus ±5%) and extended lower temperature rating (-55°C versus -40°C).

Selection of the ECH-U1H223GX5 requires evaluation of mounting compatibility. The transition from radial through-hole to surface-mount 1210 package necessitates circuit board layout modification and assembly process adjustment. The substitute is ROHS3 compliant, meeting current environmental and regulatory requirements.

For applications requiring through-hole mounting without board redesign, alternative through-hole film capacitors with matching electrical specifications should be evaluated from the active product portfolio.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H223GX5 directly replace the ECH-S1H223JZ on existing circuit boards?

A: No. The ECH-U1H223GX5 is a surface-mount component in 1210 package format, while the ECH-S1H223JZ is a through-hole radial component. Direct board-level substitution is not possible without circuit board redesign and assembly process modification.

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

A: Yes, for DC voltage and capacitance requirements. Both components are rated 0.022 µF at 50V DC with PPS dielectric material. The ECH-U1H223GX5 provides tighter tolerance (±2% versus ±5%) and extended temperature range (-55°C to 125°C versus -40°C to 125°C).

Q: What is the significance of the metallized-stacked construction in the ECH-U1H223GX5?

A: The metallized-stacked construction is a manufacturing technique that affects the physical form factor and performance characteristics of the film capacitor. This construction enables the compact 1210 surface-mount package while maintaining the required electrical specifications.

Q: Does the ECH-U1H223GX5 have AC voltage rating considerations?

A: The ECH-U1H223GX5 is rated for 30V AC, while the ECH-S1H223JZ does not specify an AC rating. For applications requiring AC voltage operation, the 30V AC rating of the substitute must be evaluated against circuit requirements.

Q: What compliance certifications apply to the substitute part?

A: The ECH-U1H223GX5 is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification. The substitute meets current environmental regulatory requirements for new designs and manufacturing.
