DPFF16D56J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF16D56J-F is a 5600 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPFF series. This radial polypropylene metallized film capacitor operates at 1.6 kV DC with a ±5% tolerance and is designed for high-pulse and DV/DT applications. The component is currently active in production with 720 pieces in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from multiple qualified manufacturers.

Substitute Part Grouping Explanation

Substitution of the DPFF16D56J-F is permissible with parts that maintain the following critical parameters:

• Capacitance Value: 5600 pF (exact match required)
• Tolerance: ±5% (matching tolerance specification)
• Voltage Rating - DC: 1600V (1.6kV) minimum (equal or higher acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (material class must match)
• Operating Temperature Range: -55°C ~ 105°C (must encompass or equal the specified range)
• Mounting Type: Through Hole (mechanical compatibility requirement)
• Package / Case: Radial (form factor requirement)
• Termination: PC Pins (lead configuration requirement)
• RoHS Status: ROHS3 Compliant (regulatory compliance requirement)

The substitute part BFC238350562 meets all critical substitution criteria. Variations in physical dimensions, lead spacing, and AC voltage rating do not preclude substitution when the above parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the DPFF16D56J-F and BFC238350562 are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

The DPFF16D56J-F offers higher inventory availability (720 pieces) compared to the BFC238350562 (1812 pieces). The BFC238350562 provides a more compact physical footprint with reduced lead spacing, which may be advantageous in space-constrained PCB layouts. The AC voltage rating of the BFC238350562 (550V) exceeds that of the DPFF16D56J-F (500V), providing additional margin in AC applications.

Selection between these parts should be based on PCB layout constraints, lead spacing compatibility with existing through-hole patterns, and component availability at the time of procurement. Both parts satisfy the electrical and thermal requirements for high-pulse and DV/DT applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the BFC238350562 be used as a direct replacement for the DPFF16D56J-F in existing designs?

A: The BFC238350562 is electrically equivalent to the DPFF16D56J-F for all critical parameters including capacitance, tolerance, DC voltage rating, dielectric material, and operating temperature range. However, the reduced physical dimensions and different lead spacing (0.591" versus 0.720") require verification of PCB through-hole pattern compatibility before substitution.

Q: What is the significance of the different AC voltage ratings between these parts?

A: The DPFF16D56J-F is rated for 500V AC while the BFC238350562 is rated for 550V AC. Both parts meet the same 1600V DC requirement. The higher AC rating of the BFC238350562 provides additional operational margin in AC applications but does not affect DC circuit performance.

Q: Are both parts suitable for high-pulse and DV/DT applications?

A: Yes. Both the DPFF16D56J-F and BFC238350562 are specified for high-pulse and DV/DT applications and share identical polypropylene metallized dielectric construction, which is the standard material for these application classes.

Q: What are the compliance and regulatory considerations for these parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component use in regulated markets. Both carry EAR99 export classification.

Q: How do the physical dimensions affect component selection?

A: The DPFF16D56J-F measures 33.00mm x 16.50mm with 18.30mm lead spacing, while the BFC238350562 measures 17.50mm x 6.00mm with 15.00mm lead spacing. The BFC238350562 is significantly more compact. PCB layout and through-hole pattern spacing must accommodate the selected part's lead configuration.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage, transport, or assembly.
