DPPM12D1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPPM12D1K-F is a 1000 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPPM series. This polypropylene metallized radial capacitor operates at 1.2 kV DC and is designed for high-frequency switching, high-pulse, DV/DT, and snubber applications. The part is currently active in production with 1025 units in stock. Equivalent and substitute parts are identified when capacitance, tolerance, dielectric material, mounting type, and termination remain compatible within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPPM12D1K-F are identified based on the following substitution criteria:

Primary Substitution Criteria (Must Match):

• Capacitance: 1000 pF
• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Type: Through Hole
• Termination: PC Pins
• Package Type: Radial

Secondary Compatibility Parameters (Allowable Variation):

• Voltage Rating - DC: Equal to or greater than 1200V
• Voltage Rating - AC: Equal to or greater than 475V
• Tolerance: ±10% or tighter
• Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
• Lead Spacing: 0.827" (21.00mm) preferred for direct PCB compatibility
• RoHS Compliance: ROHS3 Compliant

Two substitute parts meet these criteria with documented compatibility:

1. DPPM20D1K-F (Upgrade Substitute): Higher voltage rating (2.0 kV DC) within the same DPPM series, identical capacitance and tolerance, compatible lead spacing.

2. 715P102516LD3 (Similar Substitute): Different series (Orange Drop® 715P), tighter tolerance (±5%), higher voltage rating (1.6 kV DC), different physical dimensions and lead spacing, narrower operating temperature range (-55°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

DPPM20D1K-F (Upgrade Substitute): This part is the primary substitute for the DPPM12D1K-F. Both parts are from the same DPPM series manufactured by Cornell Dubilier Electronics. The DPPM20D1K-F provides a higher DC voltage rating (2.0 kV versus 1.2 kV) while maintaining identical capacitance (1000 pF), tolerance (±10%), operating temperature range (-40°C ~ 105°C), and lead spacing (0.827"). Physical dimensions are nearly identical with only marginal increases in width (7.00mm versus 6.50mm) and height (14.00mm versus 13.00mm). Both parts are ROHS3 compliant and active in production. The DPPM20D1K-F is suitable for direct substitution in applications requiring equal or higher voltage stress margins.

715P102516LD3 (Similar Substitute): This part is from the Orange Drop® 715P series and shares the same capacitance (1000 pF) and dielectric material (polypropylene metallized). The 715P102516LD3 offers a tighter tolerance (±5% versus ±10%) and higher DC voltage rating (1.6 kV). However, this part has different physical dimensions (0.291" Dia x 1.252" L versus 0.984" L x 0.256" W), a different lead spacing (0.720" versus 0.827"), and a narrower operating temperature range (-55°C ~ 85°C versus -40°C ~ 105°C). The 715P102516LD3 is ROHS3 compliant and active in production. This part is suitable for substitution only when PCB layout accommodates the different lead spacing and physical form factor, and when the operating temperature range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can DPPM20D1K-F be used as a direct replacement for DPPM12D1K-F?

A: Yes. The DPPM20D1K-F is a direct substitute. Both parts have identical capacitance (1000 pF), tolerance (±10%), operating temperature range (-40°C ~ 105°C), lead spacing (0.827"), and termination (PC Pins). The DPPM20D1K-F provides higher voltage rating (2.0 kV DC versus 1.2 kV DC) and is suitable for applications where the original part is specified.

Q: What are the physical differences between DPPM12D1K-F and DPPM20D1K-F?

A: The DPPM20D1K-F is slightly larger. Width increases from 6.50mm to 7.00mm, and height increases from 13.00mm to 14.00mm. Length remains 25.00mm. Lead spacing is identical at 21.00mm. These dimensional differences are minor and typically do not affect PCB layout compatibility.

Q: Can 715P102516LD3 replace DPPM12D1K-F on the same PCB?

A: Not without PCB modification. The 715P102516LD3 has a different lead spacing (18.30mm versus 21.00mm) and different physical dimensions (cylindrical form factor versus rectangular). PCB holes and trace routing must be verified before substitution. Additionally, the operating temperature range is narrower (-55°C ~ 85°C versus -40°C ~ 105°C).

Q: What is the key difference in tolerance between these parts?

A: DPPM12D1K-F and DPPM20D1K-F both have ±10% tolerance. The 715P102516LD3 has tighter ±5% tolerance, which may be beneficial in precision applications but is not required for direct substitution.

Q: Are all three parts RoHS compliant?

A: Yes. DPPM12D1K-F, DPPM20D1K-F, and 715P102516LD3 are all ROHS3 compliant and REACH unaffected.

Q: Which substitute part has the highest voltage rating?

A: DPPM20D1K-F has the highest DC voltage rating at 2000V (2.0 kV), followed by 715P102516LD3 at 1600V (1.6 kV), and DPPM12D1K-F at 1200V (1.2 kV).

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: All three parts are rated for high-frequency switching and high-pulse DV/DT applications. Substitution is based on voltage rating, capacitance, tolerance, and physical compatibility. Electrical performance in switching circuits is determined by these parameters, all of which are matched or exceeded in the substitute parts.
