DPFF6S1J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF6S1J-F is a 10000 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPFF series. This radial polypropylene metallized capacitor is rated for 630V DC and 200V AC operation across an operating temperature range of -55°C to 105°C. The component is designed for high pulse and DV/DT applications requiring through-hole mounting.

The part maintains Active product status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility parameters are satisfied across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPFF6S1J-F are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 10000 pF (exact match required)
• Tolerance: ±5% (exact match required)
• DC voltage rating: 630V minimum (equal or higher acceptable)
• Dielectric material: Polypropylene (PP), Metallized (required for application compatibility)
• Operating temperature range: -55°C to 105°C (minimum required)
• Applications: High Pulse, DV/DT (required for intended use)

Mechanical Compatibility Criteria:

• Mounting type: Through Hole (required for PCB integration)
• Package / Case: Radial (required for form factor)
• Termination: PC Pins (required for soldering compatibility)

The identified substitute parts B32620A6103J000 and B32621A6103J000 satisfy all electrical equivalence criteria. Both are manufactured by EPCOS - TDK Electronics in the B3262* MKP High Pulse series. Variations in physical dimensions and lead spacing exist between the main part and substitutes, requiring verification of PCB layout compatibility during component selection.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with ROHS3 compliance and REACH unaffected classification, confirming regulatory alignment for current manufacturing and deployment.

DPFF6S1J-F (CDE): Primary specification with 200V AC rating. Larger physical footprint (24.10mm x 11.40mm) with 9.50mm lead spacing. Suitable for applications where original form factor and lead spacing are fixed in PCB design.

B32620A6103J000 (EPCOS - TDK): Compact stacked construction (10.00mm x 5.00mm) with 7.50mm lead spacing. Higher AC voltage rating (400V) provides additional margin. Smallest physical profile among the three options. Lead spacing reduction requires PCB layout compatibility assessment.

B32621A6103J000 (EPCOS - TDK): Intermediate stacked construction (13.00mm x 4.00mm) with 10.00mm lead spacing. Higher AC voltage rating (400V). Lead spacing matches the original DPFF6S1J-F specification (9.50mm nominal to 10.00mm), reducing PCB layout modification requirements. Highest inventory availability (80189 pcs) among substitute options.

Selection between substitute parts depends on PCB layout constraints and lead spacing compatibility. The B32621A6103J000 offers closest mechanical compatibility with the original DPFF6S1J-F while maintaining full electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can B32620A6103J000 or B32621A6103J000 be used as direct replacements for DPFF6S1J-F?

A: Both EPCOS - TDK parts satisfy all electrical specifications: 10000 pF capacitance, ±5% tolerance, 630V DC rating, polypropylene metallized dielectric, -55°C to 105°C operating range, and high pulse/DV/DT application suitability. Physical dimensions and lead spacing differ, requiring PCB layout verification before substitution.

Q: What is the difference between the two EPCOS - TDK substitute parts?

A: B32620A6103J000 and B32621A6103J000 differ in physical dimensions and lead spacing. B32620A6103J000 measures 10.00mm x 5.00mm with 7.50mm lead spacing. B32621A6103J000 measures 13.00mm x 4.00mm with 10.00mm lead spacing. Both deliver identical electrical performance at 630V DC and 400V AC ratings.

Q: Why do the substitute parts have higher AC voltage ratings (400V) than the original (200V)?

A: The substitute parts are rated for 400V AC operation, which exceeds the original 200V AC specification. Higher voltage ratings do not affect performance in applications operating at lower voltages. The 630V DC rating remains identical across all three parts.

Q: Are there lead spacing compatibility issues with the substitute parts?

A: The original DPFF6S1J-F has 9.50mm lead spacing. B32620A6103J000 has 7.50mm spacing (1.00mm reduction), and B32621A6103J000 has 10.00mm spacing (0.50mm increase). PCB hole patterns must accommodate these variations. B32621A6103J000 provides closest spacing compatibility.

Q: Do all three parts meet current regulatory requirements?

A: All three parts are ROHS3 compliant and REACH unaffected, confirming compliance with current environmental and hazardous substance regulations. All maintain Active product status.

Q: What is the significance of the stacked construction in the EPCOS - TDK parts?

A: Stacked construction in B32620A6103J000 and B32621A6103J000 refers to the internal arrangement of metallized polypropylene film layers. This design enables compact physical dimensions while maintaining full electrical specifications. Stacked and non-stacked constructions are electrically equivalent for the specified parameters.

Q: Which substitute part offers the best inventory availability?

A: B32621A6103J000 has the highest inventory level at 80189 pcs, compared to B32620A6103J000 at 4859 pcs. The original DPFF6S1J-F has 740 pcs available.
