MMWA05P1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA05P1K-F is a 0.1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) designed for general-purpose applications requiring polyester dielectric construction with metallized axial termination. This component operates across a temperature range of -55°C to 125°C and is rated for 50V DC operation with ±10% capacitance tolerance. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent capacitance and tolerance specifications are required but alternative voltage ratings, physical dimensions, or temperature operating ranges better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMWA05P1K-F is permissible when the following core electrical parameters remain constant:

• Capacitance value: 0.1 µF
• Capacitance tolerance: ±10%
• Dielectric material: Polyester, Metallized
• Mounting type: Through Hole
• Package type: Axial
• Termination style: PC Pins

The substitute part 104MWR100K meets these core requirements. This part is manufactured by Cornell Dubilier / Illinois Capacitor and belongs to the MWR series. While the substitute maintains identical capacitance and tolerance specifications, it features a higher DC voltage rating (100V versus 50V), a higher AC voltage rating (63V versus 35V), a reduced operating temperature range (-40°C to 105°C versus -55°C to 125°C), and a smaller physical footprint (0.236" Dia x 0.453" L versus 0.220" Dia x 0.563" L). The substitute part is also ROHS3 compliant and carries the same ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MMWA05P1K-F and 104MWR100K maintain Active product status and full ROHS3 compliance, ensuring regulatory alignment for current manufacturing and deployment. The MMWA05P1K-F is appropriate for applications operating within the -55°C to 125°C temperature envelope with DC voltage requirements not exceeding 50V. The 104MWR100K is suitable for applications where higher voltage margins are required (100V DC rating) or where the reduced operating temperature range (-40°C to 105°C) is acceptable. The 104MWR100K provides a compact physical profile, which may be advantageous in space-constrained PCB layouts. Both parts carry identical ECCN and HTSUS classifications, supporting consistent supply chain documentation. Selection between these parts depends on application-specific voltage requirements, thermal operating conditions, and available board space.

Frequently Asked Questions (FAQ)

Q: Can the 104MWR100K replace the MMWA05P1K-F in all applications?

A: The 104MWR100K is electrically compatible for applications where the operating temperature range does not fall below -40°C and where the 100V DC rating does not create design conflicts. The substitute part's reduced operating temperature minimum (-40°C versus -55°C) restricts use in extreme cold environments. Physical dimensions differ, requiring PCB layout verification.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (50V DC for MMWA05P1K-F versus 100V DC for 104MWR100K), operating temperature range (-55°C to 125°C versus -40°C to 105°C), and physical dimensions (0.220" Dia x 0.563" L versus 0.236" Dia x 0.453" L). Capacitance, tolerance, dielectric material, and termination style are identical.

Q: Are both parts suitable for high-temperature applications?

A: The MMWA05P1K-F supports operation up to 125°C, making it suitable for high-temperature environments. The 104MWR100K is rated to 105°C maximum, limiting its use in applications requiring sustained operation above this temperature.

Q: Do these parts have different packaging options?

A: Both parts are supplied in axial through-hole packages with PC pin termination. The MMWA05P1K-F is available in standard inventory quantities, while the 104MWR100K is available in bulk packaging with higher stock levels.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8532.25.0010. No regulatory differentiation exists between the two parts.
