DPFF16S1J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF16S1J-F is a 10000 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPFF series. This radial polypropylene metallized film capacitor is rated for 1600V DC and 500V AC operation across a temperature range of -55°C to 105°C. The component is designed for high-pulse and DV/DT applications requiring reliable energy storage and filtering in demanding electrical environments. With Active product status and ROHS3 compliance, the DPFF16S1J-F remains in current production. Equivalent substitute parts are identified based on matching electrical specifications, dielectric material, voltage ratings, and mechanical compatibility to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPFF16S1J-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 10000 pF (exact match)
• Tolerance: ±5% (exact match)
• Voltage Rating - DC: 1600V (1.6kV) minimum
• Voltage Rating - AC: 500V minimum
• Dielectric material: Polypropylene (PP), Metallized (exact match)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match)
• Package type: Radial (exact match)
• Termination: PC Pins (exact match)
• Operating temperature range: -55°C to 105°C minimum (exact match)

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status
• Active product status

The substitute part R745I2100AA00J from KEMET meets all electrical and mechanical equivalence criteria. Physical dimensions and lead spacing may vary within the radial package category while maintaining circuit board compatibility through standard through-hole mounting practices.

Engineering Selection Recommendations

Primary Selection - DPFF16S1J-F: The DPFF16S1J-F remains the specified component for original design requirements. Active product status and current manufacturing ensure long-term availability and consistent performance characteristics. ROHS3 compliance and REACH Unaffected status satisfy regulatory requirements for industrial and commercial applications.

Substitute Selection - R745I2100AA00J: The KEMET R745I2100AA00J provides full electrical and mechanical equivalence for applications requiring component substitution due to supply constraints or procurement optimization. Identical capacitance, voltage ratings, dielectric material, temperature range, and mounting configuration ensure direct functional replacement. Active product status and equivalent compliance certifications (ROHS3, REACH Unaffected) support regulatory conformance. Physical dimensions differ (18.00mm L x 6.00mm W vs. 33.00mm L x 17.80mm W) and lead spacing varies (15.00mm vs. 18.30mm), requiring circuit board layout verification prior to implementation.

Both components are suitable for high-pulse and DV/DT applications within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can R745I2100AA00J be used as a direct replacement for DPFF16S1J-F?

A: Yes, R745I2100AA00J provides electrical equivalence across all critical parameters: 10000 pF capacitance, ±5% tolerance, 1600V DC / 500V AC ratings, polypropylene metallized dielectric, -55°C to 105°C operating range, through-hole radial mounting, and PC pin termination. Physical dimensions and lead spacing differ; circuit board layout must be verified for mechanical compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Exact capacitance match (10000 pF), (2) Identical tolerance (±5%), (3) Voltage ratings meeting or exceeding 1600V DC and 500V AC, (4) Polypropylene metallized dielectric material, (5) Through-hole radial package type, (6) PC pin termination, (7) Operating temperature range of -55°C to 105°C, and (8) ROHS3 and REACH compliance status.

Q: Are there differences in physical dimensions between these parts?

A: Yes. The DPFF16S1J-F measures 33.00mm L x 17.80mm W with 18.30mm lead spacing. The R745I2100AA00J measures 18.00mm L x 6.00mm W with 15.00mm lead spacing. Both are radial through-hole packages; circuit board layout must accommodate the dimensional variation.
