MMWA2W1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA2W1K-F is a 1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the MMWA series. This axial-mounted, through-hole component operates across a temperature range of -55°C to 125°C and is rated for 250V DC / 125V AC applications. The capacitor features polyester metallized dielectric construction with ±10% tolerance and is ROHS3 compliant. The part is currently active in production with 1068 units in stock.

Equivalent and substitute parts are identified based on matching critical electrical specifications including capacitance value, voltage ratings, dielectric material, tolerance, and physical form factor. Substitute components maintain functional compatibility within the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMWA2W1K-F are identified through equivalence in the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 1 µF (exact match required)
• DC voltage rating: 250V (minimum requirement met)
• AC voltage rating: 125V or higher
• Tolerance: ±10%
• Dielectric material: Polyester, Metallized

Mechanical Equivalence Criteria:

• Mounting type: Through Hole
• Package form: Axial
• Termination style: PC Pins

Compliance Equivalence Criteria:

• RoHS3 compliance status
• REACH unaffected status
• ECCN classification: EAR99

The substitute part 150105K250JE meets all electrical, mechanical, and compliance requirements for direct substitution. Both components share identical capacitance, DC voltage rating, tolerance, dielectric material, mounting configuration, and regulatory compliance status. Physical dimensions vary slightly within acceptable tolerances for axial film capacitors.

Parameter Comparison

Engineering Selection Recommendations

The 150105K250JE serves as a direct substitute for the MMWA2W1K-F based on electrical and mechanical parameter equivalence. Both components are manufactured by Cornell Dubilier Electronics and maintain active production status.

Selection Basis:

The substitute part maintains all critical electrical specifications: 1 µF capacitance, 250V DC rating, ±10% tolerance, and polyester metallized dielectric construction. The AC voltage rating of the substitute (160V) exceeds the original specification (125V), providing enhanced performance margin in AC applications.

Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The identical operating temperature range (-55°C to 125°C) ensures thermal performance equivalence across all specified operating conditions.

Physical dimensions show minor variation within acceptable tolerances for axial film capacitor form factors. The substitute exhibits slightly reduced diameter (10.50mm versus 10.90mm) and marginally increased length (28.00mm versus 27.00mm), which remains compatible with standard through-hole PCB layouts designed for axial components.

Frequently Asked Questions (FAQ)

Q: Can the 150105K250JE replace the MMWA2W1K-F in all applications?

A: Yes. The substitute part meets or exceeds all electrical specifications of the original component. Both parts share identical capacitance (1 µF), DC voltage rating (250V), tolerance (±10%), dielectric material (polyester metallized), and operating temperature range (-55°C to 125°C). The substitute's higher AC voltage rating (160V versus 125V) provides additional performance margin.

Q: Are there physical compatibility concerns with the substitute part?

A: Physical dimensions differ slightly. The MMWA2W1K-F measures 0.429" diameter × 1.063" length, while the 150105K250JE measures 0.413" diameter × 1.102" length. These variations remain within acceptable tolerances for axial through-hole components and do not affect PCB mounting compatibility for standard axial component layouts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the MMWA2W1K-F and 150105K250JE are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and are manufactured by Cornell Dubilier Electronics.

Q: What is the difference between the MMWA series and the 150 series designations?

A: The MMWA2W1K-F belongs to the MMWA series, while the 150105K250JE belongs to the 150 series. Both are Cornell Dubilier Electronics product lines. The series designation reflects different product line classifications within the manufacturer's portfolio, but the electrical and mechanical specifications remain equivalent for substitution purposes.

Q: Is the substitute part currently in stock?

A: Yes. The 150105K250JE has 1170 units in stock as new original inventory, compared to 1068 units available for the MMWA2W1K-F.

Q: What is the moisture sensitivity level difference between these parts?

A: The MMWA2W1K-F lists moisture sensitivity as not applicable. The 150105K250JE is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This represents an equivalent or improved specification for the substitute part.
