DPFF12D82J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF12D82J-F is an 8200 pF metallized polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPFF series. This radial through-hole component is rated for 1.2 kV DC and 475 V AC operation across a temperature range of -55°C to 105°C. The part is currently active in production with 818 units in stock. Film capacitors of this specification are essential in high-pulse and high dV/dT applications where stable capacitance, low ESR, and reliable performance under transient conditions are required. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and compatibility options for applications where the original part may be unavailable or where higher voltage ratings are beneficial.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPFF12D82J-F is determined by strict equivalence in the following parameters:

Primary Equivalence Criteria:

• Capacitance value: 8200 pF (exact match required)
• Tolerance: ±5% (matching tolerance band)
• Dielectric material: Polypropylene (PP), Metallized (same material system)
• Mounting type: Through Hole (same PCB assembly method)
• Package type: Radial (same form factor)
• Termination: PC Pins (same lead configuration)
• Operating temperature range: -55°C to 105°C (same thermal specification)
• Applications: High Pulse, DV/DT (same functional class)

Allowable Variation Parameters:

• Voltage Rating - DC: Equal to or greater than 1200V
• Voltage Rating - AC: Equal to or greater than 475V
• Physical dimensions: May vary within radial package constraints
• Lead spacing: May vary within standard radial pitch tolerances
• Manufacturer: Different manufacturer acceptable if all above criteria met

The substitute part BFC238350822 meets all primary equivalence criteria and exceeds the voltage rating requirements, making it a valid substitute for applications requiring equal or higher voltage performance.

Engineering Selection Recommendations

DPFF12D82J-F Selection Criteria:

• Original design specification calls for 1.2 kV DC / 475 V AC rating
• CDE DPFF series preferred for specific application requirements
• Larger physical footprint (33.00mm x 15.20mm) required by PCB layout
• Lead spacing of 18.30mm specified for existing through-hole pattern
• Active production status with established supply chain

BFC238350822 Selection Criteria:

• Higher voltage rating (1.6 kV DC / 550 V AC) provides design margin for voltage transients
• Vishay MMKP383 series offers equivalent electrical performance
• Smaller physical footprint (17.50mm x 8.50mm) enables space optimization
• Tighter lead spacing (15.00mm) compatible with standard radial pitch PCB designs
• Active production status with 1803 units in stock
• Both parts are ROHS3 compliant and REACH unaffected

Selection between these parts depends on PCB layout constraints and voltage margin requirements. The substitute part is electrically and functionally equivalent with superior voltage ratings and reduced physical size.

Frequently Asked Questions (FAQ)

Q: Can BFC238350822 be used as a direct replacement for DPFF12D82J-F?

A: BFC238350822 is electrically equivalent in capacitance, tolerance, dielectric material, temperature range, and application class. However, physical dimensions and lead spacing differ. Direct PCB substitution requires verification that the smaller footprint (17.50mm x 8.50mm vs. 33.00mm x 15.20mm) and tighter lead spacing (15.00mm vs. 18.30mm) are compatible with the existing through-hole pattern.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The BFC238350822 is rated for 1.6 kV DC compared to 1.2 kV DC on the DPFF12D82J-F. This higher rating provides additional safety margin in applications subject to voltage transients or overvoltage conditions. The substitute part will not degrade performance in circuits designed for the lower voltage specification.

Q: Are both parts suitable for high-pulse and high dV/dT applications?

A: Yes. Both the DPFF12D82J-F and BFC238350822 are specified for high-pulse and high dV/dT applications. Metallized polypropylene film capacitors in both series are designed to handle rapid voltage changes and transient conditions without performance degradation.

Q: What are the compliance and regulatory considerations?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry Moisture Sensitivity Level 1 (unlimited), indicating no moisture sensitivity constraints during storage or handling. Both are classified under ECCN EAR99 for export control purposes.

Q: How do the physical dimensions affect component selection?

A: The DPFF12D82J-F has a larger radial package (33.00mm x 15.20mm with 18.30mm lead spacing), while BFC238350822 is more compact (17.50mm x 8.50mm with 15.00mm lead spacing). Selection depends on available PCB real estate and existing through-hole pattern design. The substitute part is suitable for space-constrained applications but requires PCB layout compatibility verification.

Q: Are there inventory considerations between these parts?

A: DPFF12D82J-F has 818 units in stock, while BFC238350822 has 1803 units available. The substitute part offers greater inventory availability for immediate procurement needs.
