MMWA2P1K Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA2P1K is a 0.1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring polyester dielectric construction with metallized electrodes. This component features a 250V DC voltage rating and ±10% capacitance tolerance in an axial through-hole package.

The MMWA2P1K carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy equipment utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMWA2P1K is determined by strict equivalence across the following critical parameters:

Electrical 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: 125V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical Dimensions: 0.240" Dia × 0.685" L / 6.10mm × 17.40mm (exact match required)
• Termination: PC Pins (exact match required)

Environmental Parameters:

• Operating Temperature Range: -55°C to 125°C (minimum requirement; wider ranges acceptable)

Substitute parts must satisfy all electrical, mechanical, and environmental parameters without deviation. Packaging format (bulk vs. standard) does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

MMWA2P1K-F is the direct substitute for MMWA2P1K. Both components are manufactured by Cornell Dubilier Electronics within the MMWA series and share identical electrical, mechanical, and environmental specifications.

The primary distinction between these parts is product status and regulatory compliance:

• MMWA2P1K is classified as obsolete, indicating discontinued production and limited availability.
• MMWA2P1K-F maintains active product status with current manufacturing support and improved regulatory compliance (ROHS3 Compliant vs. RoHS non-compliant).

For new designs, repair operations, or production requiring long-term component availability, MMWA2P1K-F is the appropriate selection. Both parts are functionally equivalent and mechanically interchangeable in all applications where the MMWA2P1K was originally specified.

Frequently Asked Questions (FAQ)

Q: Can MMWA2P1K-F be used as a direct replacement for MMWA2P1K?

A: Yes. MMWA2P1K-F is a direct substitute. All electrical parameters (capacitance, tolerance, voltage ratings, dielectric material), mechanical parameters (package type, dimensions, termination), and environmental specifications (operating temperature range) are identical between the two parts.

Q: What is the difference between MMWA2P1K and MMWA2P1K-F?

A: The primary differences are product status and regulatory compliance. MMWA2P1K is obsolete with RoHS non-compliant status. MMWA2P1K-F is an active product with ROHS3 compliance. Functionally and mechanically, the parts are equivalent.

Q: Are there any packaging differences between these parts?

A: Packaging format differs (standard vs. bulk), but this does not affect functional equivalence or circuit performance. Both parts are supplied in axial through-hole configuration with identical physical dimensions.

Q: What voltage ratings apply to this capacitor?

A: The capacitor is rated for 250V DC and 125V AC. These ratings represent the maximum continuous operating voltages. Applications requiring lower voltage operation are compatible with this component.

Q: What is the operating temperature range?

A: The operating temperature range is -55°C to 125°C. This range applies to both MMWA2P1K and MMWA2P1K-F. Applications operating within this range are fully supported.

Q: Is MMWA2P1K-F suitable for new product designs?

A: Yes. MMWA2P1K-F is an active product with current manufacturing support and improved regulatory compliance. It is the recommended choice for new designs requiring 0.1 µF film capacitors with 250V DC rating in axial through-hole configuration.

Q: What applications are these capacitors designed for?

A: Both parts are classified for general-purpose applications. The 0.1 µF capacitance value and 250V DC rating support filtering, coupling, and decoupling functions across a broad range of electronic equipment.
