DPM6W1K Equivalent & Substitute Parts

Part Overview

The DPM6W1K is a 1 µF film capacitor rated for 630V DC operation, manufactured by Cornell Dubilier Electronics (CDE) in the DPM series. This component is designed for DC link, DC filtering, and high-frequency switching applications, featuring low ESR and low ESL characteristics with polypropylene metallized dielectric construction.

The DPM6W1K is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DPM6W1K is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1 µF (exact match required)
• Voltage rating: 630V DC minimum (equal or higher acceptable)
• Dielectric type: Polypropylene (PP), Metallized
• Tolerance: ±10%
• Mounting configuration: Through Hole, Radial
• Lead spacing: 1.575" (40.00mm)
• Termination style: PC Pins
• Operating temperature range: -55°C ~ 105°C minimum

The DPM6W1K-F qualifies as a direct substitute based on full alignment with these parameters. Physical dimensions show minor variation in seated height, which does not affect electrical performance or PCB compatibility given identical lead spacing and mounting type.

Parameter Comparison

Engineering Selection Recommendations

The DPM6W1K-F is the direct equivalent for the obsolete DPM6W1K. Both components share identical electrical specifications, capacitance value, voltage ratings, dielectric composition, and mechanical dimensions critical to PCB assembly and circuit performance.

The DPM6W1K-F carries Active product status and ROHS3 compliance, providing advantages for new designs and manufacturing environments subject to regulatory requirements. The DPM6W1K-F is currently in stock with 1094 units available.

For applications where RoHS compliance is not a requirement, the DPM6W1K remains functionally equivalent where existing inventory permits. However, the transition to DPM6W1K-F is recommended for long-term supply chain stability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the DPM6W1K-F be used as a direct replacement for the DPM6W1K in existing designs?

A: Yes. The DPM6W1K-F is electrically and mechanically equivalent. Identical capacitance, voltage ratings, dielectric material, lead spacing, and mounting configuration ensure direct PCB compatibility without design modification.

Q: What is the difference in physical dimensions between these parts?

A: The seated height differs slightly: DPM6W1K measures 1.299" (33.00mm) maximum, while DPM6W1K-F measures 1.181" (30.00mm) maximum. Lead spacing remains 1.575" (40.00mm) for both. This variation does not affect PCB layout or electrical performance.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and manufacturing process, not electrical characteristics. Both parts deliver identical capacitance, voltage rating, ESR, and ESL performance.

Q: Are there any circuit applications where one part is preferred over the other?

A: No. Both parts are suitable for DC link, DC filtering, and high-frequency switching applications across the full operating temperature range of -55°C to 105°C.

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

A: Both the DPM6W1K and DPM6W1K-F require 1.575" (40.00mm) lead spacing. PCB footprints designed for either part are interchangeable.
