DPPM16D33K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPPM16D33K-F is a 3300 pF metallized polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1.6 kV DC operation. This radial through-hole component is designed for high-frequency switching applications, high-pulse environments, and snubber circuits. The part is currently active in production with 769 units in stock and carries ROHS3 compliance certification.

Substitute parts are identified when design requirements permit voltage rating upgrades, tolerance improvements, or alternative series selections while maintaining core electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the DPPM16D33K-F are classified into two categories based on allowed parameter variations:

Upgrade Substitute (DPPM20D33K-F): This part maintains identical capacitance (3300 pF), tolerance (±10%), AC voltage rating (500V), dielectric material (polypropylene metallized), mounting type (through hole), package type (radial), lead spacing (0.827"), and compliance certifications. The DC voltage rating is increased from 1.6 kV to 2.0 kV, permitting use in higher voltage applications. Physical dimensions increase marginally (height from 18.00 mm to 19.00 mm; width from 9.50 mm to 10.50 mm), remaining compatible with standard PCB layouts.

Similar Substitute (715P332516LD3): This Orange Drop® 715P series part maintains identical capacitance (3300 pF), AC voltage rating (500V), DC voltage rating (1.6 kV), dielectric material (polypropylene metallized), mounting type (through hole), and package type (radial). The tolerance is improved from ±10% to ±5%. Operating temperature range differs (-55°C to 85°C versus -40°C to 105°C). Physical dimensions and lead spacing differ significantly (diameter 0.402", length 1.252", lead spacing 0.720"), requiring PCB layout verification. MSL rating differs (not applicable versus level 1).

Parameter Comparison

Engineering Selection Recommendations

DPPM20D33K-F Selection: This upgrade substitute is appropriate when circuit design permits higher DC voltage rating operation. The part maintains all critical electrical parameters (capacitance, tolerance, AC rating, dielectric type) and thermal operating range. Marginal physical dimension increases (1 mm height, 1 mm width) are typically accommodated in standard PCB designs with 0.827" lead spacing. Both parts carry identical ROHS3 and REACH compliance certifications. Inventory availability is higher for DPPM20D33K-F (2244 units versus 769 units).

715P332516LD3 Selection: This similar substitute is appropriate when improved tolerance (±5% versus ±10%) is required and physical dimension differences can be accommodated in PCB layout. The part maintains identical capacitance, voltage ratings, and dielectric material. The reduced operating temperature upper limit (85°C versus 105°C) must be evaluated against circuit thermal requirements. Lead spacing reduction from 0.827" to 0.720" requires PCB footprint verification. ROHS3 and REACH compliance certifications are maintained. Inventory availability is higher (2101 units).

Frequently Asked Questions (FAQ)

Q: Can DPPM20D33K-F replace DPPM16D33K-F in all applications?

A: DPPM20D33K-F is a direct electrical substitute with higher voltage rating capability. The 1 mm increase in height and 1 mm increase in width are within typical PCB design tolerances for through-hole radial components. Lead spacing remains identical at 0.827". Substitution is valid when circuit design does not require the original 1.6 kV rating as a maximum constraint.

Q: What are the key differences between 715P332516LD3 and DPPM16D33K-F?

A: The 715P332516LD3 offers improved tolerance (±5% versus ±10%) and identical voltage ratings. Physical dimensions differ significantly: the 715P series uses a cylindrical form factor (0.402" diameter, 1.252" length) versus the DPPM rectangular form factor (0.984" length, 0.374" width). Lead spacing is reduced from 0.827" to 0.720", requiring PCB layout verification. Operating temperature range is narrower (-55°C to 85°C versus -40°C to 105°C).

Q: Are all three parts ROHS3 compliant?

A: Yes. DPPM16D33K-F, DPPM20D33K-F, and 715P332516LD3 all carry ROHS3 compliance certification and REACH Unaffected status.

Q: What is the lead spacing requirement for PCB design?

A: DPPM16D33K-F and DPPM20D33K-F both require 0.827" (21.00 mm) lead spacing. The 715P332516LD3 requires 0.720" (18.30 mm) lead spacing. PCB footprints must be verified before substitution with the 715P series.

Q: Which substitute has the highest inventory availability?

A: DPPM20D33K-F has 2244 units in stock, compared to 769 units for DPPM16D33K-F and 2101 units for 715P332516LD3.

Q: Can 715P332516LD3 be used in applications requiring 105°C operation?

A: No. The 715P332516LD3 operating temperature range is -55°C to 85°C. Applications requiring sustained operation above 85°C must use DPPM16D33K-F or DPPM20D33K-F, both rated to 105°C.
