DPPM12D33K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPPM12D33K-F is a 3300 pF metallized polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1200V DC and 475V AC operation. This radial through-hole component is designed for high-frequency switching, high-pulse applications, and snubber circuits. The part maintains Active product status with 805 units in current inventory stock. Substitute parts are identified when the original DPPM12D33K-F becomes unavailable, discontinued, or when design requirements necessitate alternative electrical or mechanical specifications within the same capacitance value and dielectric material class.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the DPPM12D33K-F is based on the following criteria:

Primary Matching Parameters:

• Capacitance value: 3300 pF (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)

Allowable Variation Parameters:

• Voltage rating: May be equal to or higher than 1200V DC
• Tolerance: May be tighter (lower tolerance value) than ±10%
• Operating temperature range: May be broader or narrower
• Physical dimensions: May vary within PCB layout constraints
• Lead spacing: May vary within PCB hole pattern compatibility

The substitute part 715P332516LD3 maintains identical capacitance, dielectric material, mounting type, and package configuration. It provides higher voltage rating (1600V DC vs. 1200V DC) and tighter tolerance (±5% vs. ±10%), making it electrically compatible for applications requiring the DPPM12D33K-F specifications.

Engineering Selection Recommendations

DPPM12D33K-F Selection Criteria:

• Use when original design specifies DPPM series components
• Use when operating temperature range of -40°C to 105°C is required
• Use when physical dimensions of 25.00mm x 7.50mm and 21.00mm lead spacing are PCB-constrained
• Use when ±10% tolerance meets circuit requirements
• Use when 1200V DC rating is the design specification

715P332516LD3 Selection Criteria:

• Use as substitute when DPPM12D33K-F is unavailable or discontinued
• Use when higher voltage rating (1600V DC) provides design margin
• Use when tighter tolerance (±5%) improves circuit performance
• Use when PCB layout accommodates 10.20mm x 31.80mm dimensions and 18.30mm lead spacing
• Use when operating temperature range of -55°C to 85°C is acceptable
• Use when Orange Drop® 715P series is preferred for audio and high-frequency applications

Both parts maintain ROHS3 compliance and Active product status, ensuring regulatory conformance and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 715P332516LD3 directly replace DPPM12D33K-F in all applications?

A: Electrical substitution is valid for applications where the higher voltage rating (1600V vs. 1200V) and tighter tolerance (±5% vs. ±10%) are acceptable. Physical substitution requires PCB layout verification due to different dimensions (25.00mm vs. 31.80mm length) and lead spacing (21.00mm vs. 18.30mm).

Q: What is the impact of different operating temperature ranges?

A: DPPM12D33K-F operates from -40°C to 105°C, while 715P332516LD3 operates from -55°C to 85°C. The substitute provides lower temperature capability but reduced upper temperature limit. Select based on actual circuit operating conditions.

Q: Are both parts RoHS compliant?

A: Yes, both DPPM12D33K-F and 715P332516LD3 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Does the ±5% tolerance of 715P332516LD3 provide an advantage?

A: Tighter tolerance reduces capacitance variation across the production batch, which may improve circuit performance in applications sensitive to capacitance drift. This is an advantage when circuit design requires closer tolerance control.

Q: What are the lead spacing implications for PCB design?

A: DPPM12D33K-F uses 21.00mm lead spacing; 715P332516LD3 uses 18.30mm spacing. PCB hole patterns must accommodate the selected part. Verify hole center-to-center distance before substitution.

Q: Can these parts be used interchangeably in snubber circuits?

A: Both parts are rated for snubber applications with identical capacitance and dielectric material. Electrical interchangeability is confirmed. Physical board layout must be verified for component fit.

Q: What is the inventory status for each part?

A: DPPM12D33K-F has 805 units in stock; 715P332516LD3 has 2101 units in stock. Both maintain Active product status with current availability.
