ECH-S1392JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1392JZ is a 3900 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 currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1392JZ is determined by the following critical parameters:

• Capacitance Value: 3900 pF (exact match required)
• Tolerance: ±5% (acceptable range for equivalent function)
• Voltage Rating - DC: 100V minimum (equal or higher acceptable)
• Mounting Type: Through Hole (mechanical compatibility)
• Package Type: Radial (physical form factor)
• Lead Spacing: 0.197" (5.00mm) (PCB layout compatibility)
• Termination: PC Pins (soldering compatibility)

The Cornell Dubilier Electronics (CDE) part 168392J100A-F meets these substitution criteria with identical capacitance, tolerance, voltage rating, mounting type, package configuration, and lead spacing. Dielectric material differs (Polyester, Metallized vs. Polyphenylene Sulfide), but both materials satisfy the electrical requirements for this application category.

Parameter Comparison

Engineering Selection Recommendations

The 168392J100A-F from Cornell Dubilier Electronics is a direct functional equivalent for the obsolete ECH-S1392JZ. Both components share identical electrical specifications: 3900 pF capacitance, ±5% tolerance, and 100V DC rating. The substitute part offers superior product status (Active vs. Obsolete), ensuring long-term availability and supply chain continuity.

The Cornell Dubilier part provides additional compliance advantages, including ROHS3 certification and REACH compliance status, which may be required for new production or regulated applications. The extended lower operating temperature range (-55°C vs. -40°C) provides additional thermal margin in demanding environments.

Physical dimensions of the substitute are smaller, which may provide PCB layout benefits. Lead spacing remains identical at 0.197" (5.00mm), ensuring direct PCB compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 168392J100A-F replace the ECH-S1392JZ in existing designs?

A: Yes. Both components have identical capacitance (3900 pF), tolerance (±5%), voltage rating (100V DC), lead spacing (5.00mm), and termination type (PC Pins). The radial through-hole package and mounting type are identical, allowing direct substitution on existing PCBs.

Q: What is the difference in dielectric material, and does it affect performance?

A: The ECH-S1392JZ uses Polyphenylene Sulfide (PPS) dielectric, while the 168392J100A-F uses Polyester, Metallized dielectric. Both materials are suitable for film capacitor applications and meet the electrical requirements for this capacitance and voltage rating. Material selection does not affect functional compatibility in this application category.

Q: Are there any compliance or regulatory differences?

A: The 168392J100A-F is ROHS3 compliant and REACH unaffected, providing regulatory advantages for new production. The ECH-S1392JZ status information for these certifications is not provided. Both parts carry EAR99 ECCN classification and 8532.25.0010 HTSUS code.

Q: Will the smaller physical size of the substitute part affect PCB layout?

A: The 168392J100A-F is physically smaller (7.20mm x 2.50mm vs. 10.00mm x 4.50mm) and has lower seated height (6.50mm vs. 8.00mm). Lead spacing remains identical at 5.00mm, ensuring PCB footprint compatibility. The smaller size may provide additional PCB routing flexibility.

Q: What is the operating temperature range difference?

A: The 168392J100A-F operates from -55°C to 125°C, compared to -40°C to 125°C for the ECH-S1392JZ. The substitute part provides 15°C additional margin at the lower temperature extreme, beneficial for applications in cold environments or with stringent thermal specifications.
