DPPM16S1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPPM16S1K-F is a 10000 pF metallized polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1600V DC operation. This radial through-hole component is designed for high-frequency switching applications, high-pulse environments, and snubber circuits. The part maintains Active product status with 940 units in current inventory stock.

Substitute parts are identified when equivalent capacitance and tolerance specifications are maintained while allowing variation in voltage rating, physical dimensions, or packaging configuration. Alternative models ensure design flexibility and supply chain continuity for applications where the primary part may face availability constraints.

Substitute Part Grouping Explanation

Substitution eligibility for the DPPM16S1K-F is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Non-Negotiable):

• Capacitance value: 10000 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 1.043 inches / 26.50 mm (exact match required)
• Termination: PC Pins (exact match required)
• Operating temperature range: -40°C to 105°C (exact match required)

Allowable Variation Parameters:

• Voltage rating (DC): May be equal to or greater than 1600V
• Voltage rating (AC): May be equal to or greater than 500V
• Physical dimensions (length and width): Allowable variation within radial package constraints
• Height (seated): Allowable variation within radial package constraints
• Packaging configuration: Bulk or alternative packaging acceptable

The DPPM20S1K-F qualifies as a substitute because it maintains all primary criteria while providing an elevated DC voltage rating of 2000V, suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

Engineering Selection Recommendations

DPPM16S1K-F Selection Criteria:

• Applications operating at or near 1600V DC maximum rating
• Space-constrained designs where minimum width (0.472") is required
• Standard voltage margin applications in high-frequency switching circuits
• Snubber and high-pulse environments at specified voltage levels
• Active product status with established supply chain (940 units in stock)

DPPM20S1K-F Selection Criteria:

• Applications requiring elevated voltage margin above 1600V DC specification
• Designs operating in high-voltage stress environments where 2000V rating provides additional safety factor
• Equivalent electrical performance with enhanced voltage headroom
• Active product status with available inventory (704 units in stock)
• Acceptable for PCB layouts accommodating 0.079" additional width (0.551" vs. 0.472")

Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL Level 1 rating. Lead spacing remains constant at 1.043 inches, ensuring direct PCB footprint compatibility. Height-seated dimension is identical at 0.925 inches maximum.

Frequently Asked Questions (FAQ)

Q: Can DPPM20S1K-F replace DPPM16S1K-F in existing designs?

A: Yes, provided the PCB layout accommodates the increased width of 0.551 inches (versus 0.472 inches). All electrical parameters, lead spacing, height, and termination are identical. The elevated 2000V DC rating is backward-compatible with 1600V applications.

Q: What is the physical dimension difference between these parts?

A: The primary difference is width: DPPM16S1K-F measures 0.472 inches wide, while DPPM20S1K-F measures 0.551 inches wide. This represents a 0.079-inch increase. Length (1.220 inches) and height-seated (0.925 inches) remain identical. Lead spacing is unchanged at 1.043 inches.

Q: Are both parts suitable for high-frequency switching applications?

A: Yes. Both DPPM16S1K-F and DPPM20S1K-F are specified for high-frequency switching, high-pulse, DV/DT, and snubber applications. Electrical performance characteristics are equivalent at the 10000 pF capacitance value with ±10% tolerance.

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

A: DPPM20S1K-F provides a 400V higher DC rating (2000V versus 1600V). This allows operation in higher-voltage environments or provides additional voltage margin in designs operating near the 1600V limit. Both maintain identical 500V AC rating.

Q: Are there packaging differences between these parts?

A: DPPM16S1K-F is specified with standard packaging, while DPPM20S1K-F is available in Bulk packaging. Both use identical radial through-hole configuration with PC pin termination.

Q: Do both parts meet the same compliance standards?

A: Yes. Both DPPM16S1K-F and DPPM20S1K-F are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) rating. Both maintain Active product status.

Q: What is the lead spacing for these capacitors?

A: Both parts feature identical lead spacing of 1.043 inches (26.50 mm), ensuring direct compatibility with existing PCB footprints designed for either model.
