DMM2P1K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DMM2P1K is a 0.1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring 250V DC voltage rating with polyester metallized dielectric construction. This component features radial through-hole mounting with PC pin termination and operates across a temperature range of -55°C to 125°C.

The DMM2P1K is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and production requirements for legacy equipment utilizing this capacitor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DMM2P1K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 250V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 160V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Termination: PC Pins (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The direct manufacturer substitute DMM2P1K-F from Cornell Dubilier Electronics meets all electrical and mechanical parameters. Additional cross-manufacturer substitutes (160104J250D-F, B32529C3104K000, B32521C6104K, B32521C3104K000, B32520C3104K000) are qualified alternatives that satisfy the same parameter requirements.

Parameter Comparison

Engineering Selection Recommendations

The DMM2P1K-F is the primary substitute for the obsolete DMM2P1K. Both components are manufactured by Cornell Dubilier Electronics and share identical electrical and mechanical specifications. The DMM2P1K-F offers the advantage of active product status and ROHS3 compliance, making it suitable for new designs and applications requiring regulatory compliance.

For applications where RoHS compliance is not a requirement, the DMM2P1K remains functionally equivalent to the DMM2P1K-F. Current inventory of 874 pieces of the original DMM2P1K is available; however, the DMM2P1K-F with 1153 pieces in stock provides greater supply security for ongoing production.

Cross-manufacturer substitutes (160104J250D-F, B32529C3104K000, B32521C6104K, B32521C3104K000, B32520C3104K000) meet all specified electrical and mechanical parameters and are qualified alternatives when CDE components are unavailable.

Frequently Asked Questions (FAQ)

Q: Can the DMM2P1K-F be used as a direct replacement for the DMM2P1K?

A: Yes. The DMM2P1K-F is electrically and mechanically identical to the DMM2P1K across all critical parameters: capacitance, tolerance, voltage ratings, dielectric material, operating temperature range, mounting type, package configuration, lead spacing, and termination style.

Q: What is the difference between the DMM2P1K and DMM2P1K-F?

A: The primary differences are product status and regulatory compliance. The DMM2P1K is obsolete and RoHS non-compliant. The DMM2P1K-F is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are the cross-manufacturer substitutes (160104J250D-F, B32529C3104K000, B32521C6104K, B32521C3104K000, B32520C3104K000) compatible with the DMM2P1K?

A: Yes. These components meet all specified electrical and mechanical parameters required for substitution: 0.1 µF capacitance, ±10% tolerance, 250V DC rating, 160V AC rating, polyester metallized dielectric, through-hole radial mounting, 10.00mm lead spacing, and PC pin termination.

Q: Does lead spacing affect substitution compatibility?

A: Yes. Lead spacing of 0.394" (10.00mm) is a critical mechanical parameter. All substitute components must maintain this exact spacing to ensure proper PCB mounting and circuit board compatibility.

Q: Can substitutes with higher voltage ratings be used?

A: Yes. Substitute components with voltage ratings equal to or greater than 250V DC and 160V AC are acceptable. Higher voltage ratings do not compromise circuit functionality and provide additional safety margin.

Q: Is RoHS compliance required for substitution?

A: RoHS compliance is not a substitution requirement. However, the DMM2P1K-F offers ROHS3 compliance for applications requiring regulatory adherence. The original DMM2P1K remains functionally equivalent for applications without compliance mandates.
