DPFF16D27J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF16D27J-F is a 2700 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 1.6 kV DC voltage rating and ±5% tolerance. This radial through-hole component utilizes metallized polypropylene dielectric technology and operates across a temperature range of -55°C to 105°C. The part is Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent capacitance and tolerance values are required but alternative voltage ratings, physical dimensions, or thermal specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPFF16D27J-F is based on the following core electrical and mechanical criteria:

Mandatory Matching Parameters:

• Capacitance value: 2700 pF
• Tolerance: ±5%
• Dielectric material: Polypropylene (PP), Metallized
• Mounting type: Through Hole
• Package type: Radial
• Termination: PC Pins

Allowable Variation Parameters:

• Voltage rating (DC): Equal to or greater than 1600V
• Voltage rating (AC): Equal to or greater than 500V
• Operating temperature range: Equal to or exceeding -55°C to 105°C
• Physical dimensions: May differ while maintaining radial through-hole compatibility

Engineering Selection Recommendations

DPFF16D27J-F Selection Criteria:

• Applications requiring 1.6 kV DC voltage rating with 500V AC rating
• PCB layouts designed for 0.720" (18.30mm) lead spacing
• Designs requiring the specific physical envelope of 33.00mm x 14.00mm
• Operating temperature ceiling of 105°C is sufficient

B32672L8272J000 Selection Criteria:

• Applications requiring higher voltage margin with 2.0 kV DC rating and 700V AC rating
• PCB layouts compatible with 0.591" (15.00mm) lead spacing
• Space-constrained designs benefiting from smaller physical dimensions (18.00mm x 5.00mm)
• Applications requiring extended upper operating temperature to 110°C
• High frequency and switching applications per series designation

Both parts maintain ROHS3 compliance and Active product status. Selection between these parts depends on PCB layout constraints, voltage margin requirements, and available board space. The substitute part provides higher voltage ratings and improved thermal range within a smaller footprint.

Frequently Asked Questions (FAQ)

Q: Can B32672L8272J000 directly replace DPFF16D27J-F on existing PCBs?

A: Direct replacement requires PCB layout verification. The substitute part has different lead spacing (0.591" versus 0.720") and smaller physical dimensions. PCB hole patterns and component placement must accommodate these differences.

Q: Are the capacitance and tolerance values identical between these parts?

A: Yes. Both parts are rated at 2700 pF with ±5% tolerance, ensuring equivalent electrical performance in this parameter.

Q: What is the voltage rating advantage of the substitute part?

A: The B32672L8272J000 is rated for 2000V DC and 700V AC, compared to the DPFF16D27J-F at 1600V DC and 500V AC. This provides a 400V DC margin and 200V AC margin for applications requiring higher voltage stress capability.

Q: Do both parts use the same dielectric material?

A: Yes. Both parts utilize metallized polypropylene (PP) dielectric, ensuring equivalent electrical characteristics and performance in high pulse and DV/DT applications.

Q: What is the temperature range difference?

A: The DPFF16D27J-F operates from -55°C to 105°C, while the B32672L8272J000 extends to 110°C maximum. The substitute part provides 5°C additional upper temperature capability.

Q: Are both parts RoHS compliant?

A: Yes. Both the DPFF16D27J-F and B32672L8272J000 are ROHS3 compliant and REACH unaffected.

Q: What applications are these capacitors designed for?

A: The DPFF16D27J-F is specified for high pulse and DV/DT applications. The B32672L8272J000 is rated for high frequency, switching, high pulse, and DV/DT applications.

Q: Can the substitute part be used in applications originally designed for the main part?

A: Yes, provided PCB layout accommodates the different lead spacing and physical dimensions. The higher voltage ratings and extended temperature range of the substitute part are backward compatible with applications designed for the lower-rated main part.
