MMWA4P22K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA4P22K-F is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring 400V DC voltage rating with polyester metallized dielectric construction. This axial-lead through-hole component operates across a temperature range of -55°C to 125°C and maintains ±10% capacitance tolerance. The part is currently in active production status with 1059 units available in new original inventory. Substitute parts are identified when equivalent electrical performance can be achieved while maintaining compatibility with circuit requirements and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMWA4P22K-F are identified based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant or improve:

Critical Parameters (No Deviation Allowed):

• Capacitance value: 0.22 µF
• Dielectric material: Polyester, Metallized
• Mounting type: Through Hole
• Package type: Axial
• Termination style: PC Pins

Parameters That May Improve:

• Tolerance: Tighter tolerance (±5%) is acceptable as it represents improved performance
• Voltage rating: Equal or higher ratings maintain or enhance safety margins
• Operating temperature range: Equal or wider ranges are acceptable
• RoHS compliance: Must be maintained at ROHS3 level

The substitute part 150224J400FE meets all substitution criteria by maintaining identical capacitance, voltage ratings, dielectric material, mounting configuration, and termination style while offering improved ±5% tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

MMWA4P22K-F Selection Criteria:

• Use when ±10% tolerance specification is acceptable for the application
• Preferred when board space is constrained and the shorter 25.40mm length is required
• Suitable for general-purpose applications with standard tolerance requirements
• Active production status ensures continued availability

150224J400FE Selection Criteria:

• Use when tighter ±5% tolerance is required for improved capacitance accuracy
• Acceptable when the longer 28.00mm axial length fits within board layout constraints
• Provides enhanced performance specification with identical electrical ratings
• Higher inventory availability (3262 units) supports production volume requirements
• Bulk packaging option available

Substitution Feasibility: Both parts are manufactured by Cornell Dubilier Electronics and maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99). The primary consideration for substitution is the 2.6mm difference in axial length. Circuit board layout must accommodate the 150224J400FE's 28.00mm length. The improved ±5% tolerance of the substitute part represents a performance enhancement with no electrical or thermal disadvantage.

Frequently Asked Questions (FAQ)

Q: Can 150224J400FE directly replace MMWA4P22K-F in all applications?

A: Electrical substitution is valid. The 150224J400FE maintains identical capacitance (0.22 µF), voltage ratings (400V DC / 200V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), and termination style (PC pins). Mechanical verification is required: the substitute part is 2.6mm longer (28.00mm vs 25.40mm). Board layout must accommodate this length difference.

Q: What is the tolerance difference between these parts?

A: MMWA4P22K-F specifies ±10% tolerance, while 150224J400FE specifies ±5% tolerance. The tighter ±5% tolerance of the substitute represents improved capacitance accuracy and is considered a performance enhancement. Applications requiring ±10% tolerance can use either part.

Q: Are both parts RoHS compliant?

A: Yes. Both MMWA4P22K-F and 150224J400FE are ROHS3 compliant and REACH unaffected, maintaining identical regulatory compliance status.

Q: What is the physical dimension difference?

A: Both parts share identical diameter (0.335" / 8.50mm). The axial length differs: MMWA4P22K-F is 1.000" (25.40mm), while 150224J400FE is 1.102" (28.00mm). This 2.6mm length difference must be evaluated against available board space.

Q: Can I use 150224J400FE if my circuit requires ±10% tolerance?

A: Yes. The ±5% tolerance of 150224J400FE is tighter than the ±10% requirement, meaning it will perform within the ±10% specification window. Tighter tolerance represents improved performance.

Q: Are there inventory considerations for these parts?

A: MMWA4P22K-F has 1059 units in stock. 150224J400FE has 3262 units available in bulk packaging. For high-volume production, the substitute part offers greater inventory availability.

Q: Do these parts have different operating temperature ranges?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C, ensuring thermal performance equivalence.

Q: What packaging differences exist?

A: MMWA4P22K-F is supplied in standard packaging. 150224J400FE is available in bulk packaging, which may affect procurement and handling procedures.
