ECH-S1H822JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H822JZ is an 8200 pF 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 part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H822JZ is determined by the following critical parameters:

• Capacitance Value: Must be 8200 pF (no deviation permitted)
• Voltage Rating: Minimum 50V DC to maintain circuit safety margins
• Dielectric Material: Polyphenylene sulfide (PPS) to preserve electrical characteristics
• Operating Temperature Range: Must support the application's thermal requirements
• Tolerance: ±2% or better is acceptable as it represents improved precision over the original ±5%

The ECH-U1H822GX5 qualifies as a functional substitute based on matching capacitance, voltage rating, dielectric material, and operating temperature specifications. However, this substitute introduces a change in mounting technology from through-hole radial to surface-mount 1206 package format.

Engineering Selection Recommendations

ECH-U1H822GX5 Substitution Considerations:

The ECH-U1H822GX5 is an active product with current manufacturing support and improved specifications. It maintains the critical electrical parameters: 8200 pF capacitance, 50V DC rating, and PPS dielectric material. The substitute offers superior tolerance (±2% versus ±5%) and an extended lower operating temperature limit (-55°C versus -40°C).

The primary design change is the transition from through-hole radial mounting to surface-mount 1206 package format. This substitution requires PCB redesign and is suitable only for new production or board-level rework where layout modifications are feasible.

The ECH-U1H822GX5 is ROHS3 compliant and carries REACH Unaffected status, providing regulatory compliance advantages for modern applications.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H822GX5 be used as a direct replacement for the ECH-S1H822JZ?

A: Electrical substitution is valid based on matching capacitance (8200 pF), voltage rating (50V DC), and dielectric material (PPS). However, physical substitution is not direct due to package format differences: the original is through-hole radial, while the substitute is surface-mount 1206. PCB redesign is required.

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

A: Capacitance value (8200 pF), DC voltage rating (minimum 50V), and dielectric material (PPS) are non-negotiable. Tolerance may improve (±2% is acceptable for ±5% original). Operating temperature range must support the application environment.

Q: Does the ECH-U1H822GX5 have better specifications than the original part?

A: Yes. The substitute offers tighter tolerance (±2% versus ±5%), extended lower temperature operation (-55°C versus -40°C), and active product status with ongoing manufacturing support. It also provides ROHS3 compliance and REACH Unaffected status.

Q: What is the AC voltage rating difference between these parts?

A: The original ECH-S1H822JZ does not specify an AC voltage rating. The ECH-U1H822GX5 is rated for 30V AC. For AC applications, the 50V DC rating should be the primary design reference unless AC-specific performance is required.

Q: Are there any compliance or regulatory differences?

A: The ECH-U1H822GX5 is ROHS3 compliant and REACH Unaffected, providing regulatory advantages for modern applications. The original part's compliance status is not specified.
