ECH-S1H152JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H152JZ is a 1500 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 substitute components necessary for new designs or maintenance applications requiring equivalent electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H152JZ is determined by the following critical parameters:

• Capacitance Value: Must be 1500 pF (exact match required)
• Voltage Rating: Minimum 50V DC to maintain circuit safety margins
• Dielectric Material: Polyphenylene sulfide (PPS) for equivalent electrical characteristics
• Tolerance: ±5% or better (tighter tolerance acceptable)
• Operating Temperature: Must support -40°C ~ 125°C range or equivalent

The ECH-U1H152GX5 qualifies as a substitute based on matching capacitance, voltage rating, dielectric material, and operating temperature specifications. However, this substitute differs in mounting technology (surface mount versus through-hole) and tolerance (±2% versus ±5%), which may require circuit board redesign.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H152GX5 serves as an active substitute for the obsolete ECH-S1H152JZ when electrical parameters are the primary selection criteria. Both components share identical capacitance values, voltage ratings, and dielectric material composition. The substitute offers improved tolerance (±2% versus ±5%) and extended lower temperature operation (-55°C versus -40°C minimum).

Selection of the ECH-U1H152GX5 requires circuit board redesign due to the transition from through-hole radial mounting to surface-mount 0805 package format. The substitute is ROHS3 compliant and carries unlimited moisture sensitivity rating, supporting modern manufacturing and environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H152GX5 be used as a direct pin-for-pin replacement?

A: No. The ECH-U1H152GX5 is a surface-mount component in 0805 package format, while the ECH-S1H152JZ is a through-hole radial component. Circuit board layout and assembly process modifications are required.

Q: Does the ±2% tolerance of the substitute affect circuit performance?

A: The tighter tolerance of the ECH-U1H152GX5 (±2%) is superior to the original specification (±5%) and will not negatively impact circuit performance. Applications requiring the original ±5% tolerance will operate within specification with the substitute.

Q: Are there voltage rating differences between these components?

A: Both components are rated for 50V DC operation. The ECH-U1H152GX5 additionally specifies 30V AC rating, which was not provided for the original part. The 50V DC rating is the controlling specification for DC circuit applications.

Q: What is the temperature operating range difference?

A: The ECH-U1H152GX5 extends the lower operating temperature to -55°C compared to the ECH-S1H152JZ at -40°C. Both support 125°C maximum. This provides improved performance in cold environment applications.

Q: Is the ECH-U1H152GX5 suitable for high-frequency and switching applications?

A: The ECH-U1H152GX5 is specified for general-purpose applications. Confirmation of suitability for high-frequency and switching applications requires circuit-level analysis based on the specific frequency range and switching characteristics of the target application.
