ECH-S1272JZ Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECH-S1272JZ is a 2700 pF film capacitor manufactured by Panasonic Electronic Components, rated for 100V DC operation with ±5% tolerance. This component features a Polyphenylene Sulfide (PPS) dielectric material in a radial through-hole package, designed for high-frequency and switching applications. The product is classified as obsolete, making identification of suitable substitute components necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1272JZ is determined by the following critical parameters:

• Capacitance Value: 2700 pF (exact match required)
• Voltage Rating: 100V DC minimum
• Tolerance: ±5% (acceptable range for equivalent functionality)
• Mounting Configuration: Through-hole radial package with 5.00mm lead spacing
• Termination Style: PC pins for PCB insertion

The Cornell Dubilier Electronics (CDE) part number 168272J100A-F meets these substitution criteria. While the dielectric material differs (Polyester, Metallized versus Polyphenylene Sulfide), both materials satisfy the electrical performance requirements for this capacitance and voltage rating. The CDE substitute maintains identical lead spacing and termination style, ensuring mechanical compatibility with existing PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The ECH-S1272JZ is classified as obsolete. The 168272J100A-F from Cornell Dubilier Electronics is an active product suitable for direct substitution in applications requiring a 2700 pF, 100V film capacitor in radial through-hole configuration.

The CDE substitute is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution. The extended operating temperature range (-55°C to 125°C) of the CDE part provides additional thermal margin compared to the original Panasonic specification.

Physical dimensions differ slightly between the two parts. The CDE substitute measures 0.283" L x 0.098" W (7.20mm x 2.50mm) with a seated height of 0.256" (6.50mm), compared to the original 0.394" L x 0.177" W (10.00mm x 4.50mm) with a seated height of 0.315" (8.00mm). These dimensional differences do not affect electrical performance but may impact PCB layout considerations in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the 168272J100A-F directly replace the ECH-S1272JZ on existing PCBs?

A: Yes. Both components share identical capacitance (2700 pF), voltage rating (100V DC), tolerance (±5%), lead spacing (5.00mm), and termination style (PC pins). The radial through-hole mounting configuration is identical, allowing direct PCB insertion without modification.

Q: Why does the CDE part use a different dielectric material?

A: Polyester, Metallized and Polyphenylene Sulfide (PPS) are both suitable dielectric materials for film capacitors in this voltage and capacitance range. Both materials deliver equivalent electrical performance for the specified application parameters. Material selection reflects manufacturing process differences between manufacturers.

Q: Are there dimensional concerns when substituting the CDE part?

A: The CDE substitute is physically smaller than the original Panasonic part. Verify that the reduced dimensions (7.20mm x 2.50mm versus 10.00mm x 4.50mm) do not conflict with PCB layout constraints or mechanical clearance requirements in your specific application.

Q: What compliance certifications does the substitute part carry?

A: The 168272J100A-F is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components in the European Union and related markets.

Q: Does the CDE substitute operate across the same temperature range?

A: The CDE part operates from -55°C to 125°C, which exceeds the original specification of -40°C to 125°C. This extended lower temperature limit provides additional operational margin for applications requiring operation in cold environments.
