ECH-S1332JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1332JZ is a 3300 pF film capacitor rated at 100V DC with polyphenylene sulfide (PPS) dielectric material, designed for through-hole radial mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part is suitable for high-frequency and switching circuit applications requiring stable capacitance performance across the operating temperature range of -40°C to 125°C.

Substitute Part Grouping Explanation

Substitution for the ECH-S1332JZ is determined by the following critical parameters:

Capacitance Value: 3300 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating (DC): 100V minimum (equal or higher acceptable)
Mounting Type: Through Hole Radial (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Termination: PC Pins (exact match required)

The substitute parts identified meet all critical electrical and mechanical parameters. Dielectric material variations (polyester/PET metallized vs. PPS) are acceptable provided voltage and capacitance ratings are maintained, as both material types deliver equivalent performance in the specified application envelope.

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the ECH-S1332JZ. Selection between the two substitutes is based on application requirements and regulatory compliance:

168332J100A-F (Cornell Dubilier Electronics): This substitute provides ROHS3 compliance and REACH unaffected status. The polyester metallized dielectric delivers stable performance in general-purpose applications. Smaller physical dimensions (7.20mm x 2.50mm) may offer space advantages in compact circuit layouts compared to the original part.

B32529C1332J000 (EPCOS - TDK Electronics): This substitute includes AEC-Q200 automotive qualification in addition to ROHS3 compliance and REACH unaffected status. The polyester PET metallized stacked construction is suitable for automotive, EMI, and RFI suppression applications. Slightly larger footprint (7.30mm x 2.50mm) remains compatible with standard 5.00mm lead spacing requirements.

Both substitutes operate across -55°C to 125°C, providing extended low-temperature performance compared to the original -40°C minimum. Physical dimensions of both substitutes are smaller than the original part; PCB layout verification is required to confirm fit within existing component placement constraints.

Frequently Asked Questions (FAQ)

Q: Can 168332J100A-F and B32529C1332J000 be used interchangeably with ECH-S1332JZ?

A: Both parts meet the critical electrical parameters (3300 pF, ±5%, 100V DC) and mechanical requirements (through-hole radial, 5.00mm lead spacing, PC pins). Physical dimensions differ; verify PCB layout compatibility before substitution.

Q: What is the impact of dielectric material change from PPS to polyester/PET?

A: Both dielectric materials are film capacitor types suitable for the specified voltage and frequency ranges. The substitutes maintain the same capacitance tolerance and voltage rating. Polyester and PET materials are established alternatives in film capacitor design for equivalent performance in this application class.

Q: Are the substitute parts smaller than the original?

A: Yes. The original ECH-S1332JZ measures 10.00mm x 4.50mm with 8.50mm seated height. Both substitutes measure approximately 7.20-7.30mm x 2.50mm with 6.50mm seated height. Confirm PCB footprint and clearance requirements before implementation.

Q: Which substitute is recommended for automotive applications?

A: B32529C1332J000 carries AEC-Q200 automotive qualification and is specified for automotive and EMI/RFI suppression use. 168332J100A-F is classified for general-purpose applications.

Q: Do the substitutes meet current regulatory requirements?

A: Both substitutes are ROHS3 compliant and REACH unaffected. The original ECH-S1332JZ regulatory status is not specified; substitution with either active part addresses current compliance requirements.

Q: What is the lead spacing compatibility?

A: All three parts (original and both substitutes) share identical 0.197" (5.00mm) lead spacing, ensuring PCB footprint compatibility at the pin level.
