ECH-S1H182JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H182JZ is a 1800 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 new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H182JZ is determined by the following critical parameters:

• Capacitance Value: Must be 1800 pF (exact match required)
• Voltage Rating: Minimum 50V DC to maintain electrical safety margins
• Dielectric Material: Polyphenylene Sulfide (PPS) for equivalent electrical characteristics
• Tolerance: ±2% or better meets or exceeds the original ±5% specification
• Operating Temperature: Must support the -40°C ~ 125°C range or equivalent

The ECH-U1H182GX5 qualifies as a functional equivalent based on matching capacitance, voltage rating, dielectric material, and temperature range. However, this substitute differs in mounting technology (surface mount vs. through hole) and package format (0805 vs. radial), requiring circuit board redesign for implementation.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H182GX5 provides electrical equivalence to the ECH-S1H182JZ with the following considerations:

Electrical Compatibility: Both parts maintain 1800 pF capacitance and 50V DC rating. The substitute offers superior tolerance (±2% vs. ±5%) and extended lower temperature operation (-55°C vs. -40°C minimum).

Compliance Status: The ECH-U1H182GX5 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original ECH-S1H182JZ carries no specified RoHS status.

Availability: The ECH-U1H182GX5 is in active production with 6003 units in stock, whereas the ECH-S1H182JZ is obsolete with limited remaining inventory (956 units).

Implementation Constraint: Direct board-level substitution is not possible due to different mounting technologies (through-hole radial vs. surface-mount 0805). Circuit board redesign is required for the ECH-U1H182GX5 implementation.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H182GX5 be used as a direct replacement for the ECH-S1H182JZ?

A: No. While both parts are electrically equivalent in capacitance, voltage rating, and dielectric material, they use different mounting technologies. The ECH-S1H182JZ is a through-hole radial component, while the ECH-U1H182GX5 is a surface-mount 0805 package. Circuit board redesign is necessary.

Q: What are the critical parameters for substitution?

A: Capacitance value (1800 pF), DC voltage rating (minimum 50V), dielectric material (PPS), and operating temperature range must match or exceed the original specification. Tolerance and package format are secondary considerations.

Q: Does the ECH-U1H182GX5 meet the same temperature requirements?

A: Yes. The substitute operates from -55°C to 125°C, which exceeds the original -40°C to 125°C range.

Q: What is the tolerance difference between these parts?

A: The ECH-S1H182JZ has ±5% tolerance, while the ECH-U1H182GX5 has ±2% tolerance. The substitute provides tighter capacitance accuracy.

Q: Are there any compliance differences?

A: The ECH-U1H182GX5 is ROHS3 compliant with MSL 1 rating. The original part carries no specified compliance certifications.
