MMWA05W5M-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA05W5M-F is a 5 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general purpose applications. This axial-mounted through-hole component features a polyester metallized dielectric with a 50V DC voltage rating and ±20% capacitance tolerance. The part maintains Active product status with 726 units in current inventory stock.

Substitute parts are identified when equivalent capacitance values, compatible voltage ratings, and matching mounting configurations are available from the same manufacturer, enabling component interchangeability in circuit designs where performance parameters align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the MMWA05W5M-F is based on the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 5 µF (exact match required)
• Mounting type: Through Hole (axial configuration)
• Termination style: PC Pins
• Manufacturer: Cornell Dubilier Electronics (CDE)
• Product status: Active

Compatible Variation Parameters:

• Voltage rating: Equal to or greater than 50V DC
• Tolerance: Equal to or tighter than ±20%
• Dielectric material: Metallized film (polyester or polypropylene)
• Operating temperature range: Must encompass or exceed -55°C ~ 125°C
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The substitute part 935C1W5K-F meets all mandatory matching criteria and provides enhanced electrical performance through higher voltage rating (100V DC), improved tolerance (±10%), and alternative dielectric material (polypropylene) while maintaining through-hole axial form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MMWA05W5M-F): Select the MMWA05W5M-F when circuit design specifies polyester film dielectric characteristics, requires operation at temperatures up to 125°C, or when the 50V DC rating is sufficient for the application. This part is ROHS3 compliant and REACH unaffected, meeting current environmental standards.

Substitute Part Selection (935C1W5K-F): The 935C1W5K-F serves as a substitute when higher voltage margin is required (100V DC rating versus 50V DC), when tighter capacitance tolerance (±10% versus ±20%) improves circuit performance, or when polypropylene dielectric properties are advantageous for high-frequency or switching applications. Both parts maintain ROHS3 compliance and REACH unaffected status.

Physical Dimension Consideration: The substitute part exhibits different physical dimensions (0.642" Dia x 1.248" L versus 0.524" Dia x 1.500" L). PCB layout verification is required to confirm axial lead spacing and component body clearance compatibility with existing circuit board designs.

Temperature Range Consideration: The main part MMWA05W5M-F supports operation to 125°C, while the substitute 935C1W5K-F is rated to 105°C. Applications requiring sustained operation above 105°C require the main part specification.

Frequently Asked Questions (FAQ)

Q: Can the 935C1W5K-F directly replace the MMWA05W5M-F in all applications?

A: Direct replacement is possible when circuit design accommodates the different physical dimensions and when the maximum operating temperature requirement does not exceed 105°C. The substitute part's higher voltage rating (100V DC) and tighter tolerance (±10%) provide enhanced performance margins in most general purpose applications.

Q: What is the significance of the different dielectric materials (polyester versus polypropylene)?

A: Polyester (MMWA05W5M-F) and polypropylene (935C1W5K-F) are both metallized film materials suitable for general purpose and high-frequency applications. Polypropylene typically exhibits lower ESR and superior high-frequency performance, making the substitute advantageous for switching applications. Polyester offers broader temperature range support in this product comparison.

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

A: The MMWA05W5M-F is specified for general purpose applications. The 935C1W5K-F is explicitly rated for high-frequency and switching applications, with documented ESR of 10 mOhms. For switching circuit designs, the substitute part is the appropriate selection.

Q: Do the different physical dimensions affect PCB assembly compatibility?

A: Yes. The substitute part (0.642" Dia x 1.248" L) has a larger diameter and shorter length compared to the main part (0.524" Dia x 1.500" L). PCB layout must be verified to confirm adequate clearance around component body and lead spacing compatibility with existing through-hole positions.

Q: Are both parts currently available in inventory?

A: Yes. The MMWA05W5M-F has 726 units in stock, and the 935C1W5K-F has 884 units in stock, both listed as new original inventory.

Q: What compliance certifications apply to both parts?

A: Both the MMWA05W5M-F and 935C1W5K-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
