ECH-S1H224JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H224JZ is a 0.22 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 system maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H224JZ is determined by the following critical parameters:

• Capacitance Value: Must be 0.22 µF (exact match required)
• Voltage Rating: Minimum 50V DC to maintain circuit safety margins
• Dielectric Material: Polyphenylene sulfide (PPS) or metallized PPS variants maintain electrical performance characteristics
• Operating Temperature Range: Must support the application's thermal requirements
• Tolerance: ±5% or tighter tolerance acceptable for circuit compatibility

The ECH-U1H224GX9 qualifies as a functional equivalent based on matching capacitance, voltage rating, dielectric material, and operating temperature specifications. However, this substitute introduces a critical difference: it is a surface-mount component (2416 package) rather than a through-hole radial device, requiring circuit board redesign for implementation.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H224GX9 provides electrical equivalence to the ECH-S1H224JZ with the following considerations:

Electrical Compatibility: Both components meet the 0.22 µF capacitance and 50V voltage requirements. The substitute offers superior tolerance (±2% versus ±5%) and extended low-temperature operation (-55°C versus -40°C minimum).

Physical Incompatibility: The substitute is a surface-mount component in 2416 package format, whereas the original is a through-hole radial device. Direct board-level substitution is not possible without circuit redesign.

Compliance Status: The ECH-U1H224GX9 is active product with ROHS3 compliance and REACH unaffected status, providing long-term availability assurance compared to the obsolete ECH-S1H224JZ.

Packaging Format: The original radial through-hole configuration is not available in the active ECH-U series. Surface-mount alternatives represent the current manufacturing direction for this capacitance and voltage class.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H224GX9 be used as a direct replacement for the ECH-S1H224JZ?

A: Electrical specifications are compatible (0.22 µF, 50V, PPS dielectric). However, the ECH-U1H224GX9 is a surface-mount component (2416 package) while the ECH-S1H224JZ is through-hole radial. Direct board-level substitution requires circuit redesign and PCB layout modification.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance value (0.22 µF), voltage rating (minimum 50V DC), and dielectric material (PPS or metallized PPS) are the primary matching criteria. Tolerance and operating temperature range should meet or exceed application requirements.

Q: Is the ±2% tolerance of the ECH-U1H224GX9 compatible with circuits designed for ±5% tolerance?

A: Yes. Tighter tolerance is acceptable and provides improved circuit performance. Circuits designed for ±5% tolerance will function correctly with ±2% tolerance components.

Q: What is the temperature operating range difference between these parts?

A: The ECH-S1H224JZ operates from -40°C to 125°C, while the ECH-U1H224GX9 operates from -55°C to 125°C. The substitute provides extended low-temperature capability.

Q: Why is the ECH-S1H224JZ obsolete?

A: The product status reflects Panasonic's discontinuation of this through-hole radial film capacitor series. The ECH-U series represents the current active product line for equivalent capacitance and voltage specifications.

Q: Are there other through-hole alternatives to the ECH-S1H224JZ?

A: Based on the provided substitute list, the ECH-U1H224GX9 is the identified equivalent. This component is surface-mount only, indicating that through-hole radial options in this specification are no longer manufactured.
