ECH-S1H563JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H563JZ is a 0.056 µF film capacitor rated for 50V DC, manufactured by Panasonic Electronic Components as part of the ECHS(Z) series. 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 identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECH-S1H563JZ is determined by the following critical parameters:

• Capacitance Value: Must be 0.056 µF (exact match required)
• Voltage Rating (DC): Must be rated for minimum 50V DC
• Dielectric Material: Must be Polyphenylene Sulfide (PPS) or compatible variant
• Operating Temperature Range: Must support the required thermal envelope
• Mounting Compatibility: Physical form factor and lead configuration must accommodate the application circuit

The ECH-U1H563GX9 qualifies as a functional substitute based on matching capacitance, voltage rating, and dielectric material specifications. However, this substitute introduces a change in mounting technology from through-hole radial to surface-mount 1913 package format, which requires circuit board redesign and assembly process modification.

Engineering Selection Recommendations

For Direct Through-Hole Replacement: The ECH-S1H563JZ is obsolete with no direct through-hole equivalent available from the provided substitute list. Procurement of remaining inventory stock (700 pcs reported available) is the only option for applications requiring the original radial through-hole form factor.

For New Designs or Board Redesign: The ECH-U1H563GX9 is an active product suitable for applications where surface-mount technology can be implemented. This substitute offers improved tolerance (±2% versus ±5%), extended lower temperature rating (-55°C versus -40°C), and ROHS3 compliance. Circuit board layout and assembly process modification is required.

Compliance Considerations: Both components carry ECCN EAR99 classification and HTSUS code 8532.25.0010. The ECH-U1H563GX9 provides ROHS3 compliance and MSL 1 rating, advantageous for modern manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H563GX9 be used as a direct drop-in replacement for the ECH-S1H563JZ?

A: No. The ECH-U1H563GX9 is a surface-mount component in 1913 package format, while the ECH-S1H563JZ is a through-hole radial component. Direct substitution on existing circuit boards is not possible without PCB redesign and assembly process changes.

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

A: Both components share identical capacitance (0.056 µF) and DC voltage rating (50V). The ECH-U1H563GX9 offers tighter tolerance (±2% versus ±5%) and an additional AC voltage rating specification (30V). Operating temperature range is extended on the substitute (-55°C to 125°C versus -40°C to 125°C).

Q: Is the ECH-U1H563GX9 suitable for high-frequency and switching applications?

A: The ECH-U1H563GX9 is specified for general-purpose applications. The original ECH-S1H563JZ was designated for high-frequency and switching applications. Application-specific performance characteristics must be evaluated independently.

Q: What is the moisture sensitivity level difference, and does it matter?

A: The ECH-S1H563JZ has MSL not applicable (through-hole component). The ECH-U1H563GX9 has MSL 1 (unlimited), indicating minimal moisture sensitivity and no special storage or handling requirements for the surface-mount component.

Q: Are both components RoHS compliant?

A: The ECH-S1H563JZ RoHS status is not specified. The ECH-U1H563GX9 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
