DPPM12D15K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPPM12D15K-F is a 1500 pF polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1.2 kV DC operation. This radial through-hole component is designed for high-frequency switching, high-pulse applications, and snubber circuits. The part is currently active in production with 753 units in stock and maintains ROHS3 compliance and REACH unaffected status.

Identifying equivalent and substitute parts becomes necessary when the original part is unavailable, when design requirements shift within acceptable electrical parameters, or when alternative packaging or performance characteristics better suit system requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the DPPM12D15K-F is determined by the following critical parameters:

Capacitance value must be 1500 pF
Dielectric material must be polypropylene (PP), metallized
Mounting type must be through-hole radial configuration
Termination must be PC pins
DC voltage rating must meet or exceed 1200V
AC voltage rating must meet or exceed 475V
Operating temperature range must encompass the application requirements
RoHS and REACH compliance status must be maintained

The 715P152516LD3 qualifies as a substitute part because it maintains the same capacitance value, dielectric material, mounting configuration, and termination type while exceeding the voltage ratings of the original part.

Engineering Selection Recommendations

The 715P152516LD3 (Orange Drop® 715P series) is a qualified substitute for the DPPM12D15K-F based on the following engineering criteria:

Both parts maintain identical capacitance values, dielectric composition, mounting configuration, and regulatory compliance status. The substitute part provides higher DC and AC voltage ratings, which ensures operation within safe margins in applications designed for the original 1.2 kV specification.

The substitute part features a tighter tolerance specification (±5% versus ±10%), which may provide improved circuit performance in precision applications. However, the operating temperature range differs: the substitute operates from -55°C to 85°C compared to the original -40°C to 105°C. Selection between these parts should be based on the specific temperature requirements of the application.

Both parts are manufactured by Cornell Dubilier Electronics and maintain current active production status with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 715P152516LD3 be used as a direct replacement for the DPPM12D15K-F in all applications?

A: The 715P152516LD3 is electrically compatible for applications operating within its temperature range (-55°C to 85°C). If your application requires operation above 85°C, the original DPPM12D15K-F is required. Both parts share identical capacitance, dielectric material, and mounting configuration.

Q: What is the significance of the voltage rating difference?

A: The 715P152516LD3 is rated for 1600V DC and 500V AC, exceeding the DPPM12D15K-F specifications of 1200V DC and 475V AC. This higher rating provides additional safety margin and does not negatively impact circuit performance when used in applications designed for lower voltages.

Q: How do the tolerance specifications affect substitution?

A: The DPPM12D15K-F carries ±10% tolerance while the 715P152516LD3 carries ±5% tolerance. The tighter tolerance of the substitute part may improve circuit precision but does not prevent substitution in applications designed for ±10% tolerance.

Q: Are there physical dimension differences between these parts?

A: Yes. The DPPM12D15K-F measures 0.984" L x 0.256" W with 0.512" seated height and 0.827" lead spacing. The 715P152516LD3 measures 0.319" Dia x 1.252" L with 0.610" seated height and 0.720" lead spacing. PCB layout and clearance requirements must be verified before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the DPPM12D15K-F and 715P152516LD3 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.
