MMWA05P22K Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA05P22K is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring polyester dielectric construction with metallized electrodes in axial through-hole configuration. This part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance. The MMWA series represents a legacy product line, making substitute part identification critical for design continuity and component availability.

Substitute Part Grouping Explanation

Substitution of the MMWA05P22K is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 50V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 35V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match or superior range acceptable)

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Size / Dimension: 0.240" Dia x 0.685" L / 6.10mm x 17.40mm (exact match required for PCB compatibility)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all electrical and mechanical criteria simultaneously to ensure functional and physical compatibility within existing circuit designs and PCB layouts.

Engineering Selection Recommendations

MMWA05P22K-F as Direct Substitute:

The MMWA05P22K-F is a direct functional and mechanical equivalent of the MMWA05P22K. Both parts share identical electrical specifications, physical dimensions, and mounting characteristics. The primary distinction between these parts is product status and regulatory compliance:

• Product Status: The MMWA05P22K-F is classified as Active, whereas the original MMWA05P22K is Obsolete. Active status ensures continued manufacturer support, availability, and technical documentation.

• RoHS Compliance: The MMWA05P22K-F achieves ROHS3 compliance, while the MMWA05P22K is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the MMWA05P22K-F is the appropriate selection.

• REACH Status: Both parts maintain identical REACH Unaffected status, indicating no regulatory restriction on use or procurement.

For new designs, system upgrades, or procurement cycles requiring regulatory compliance, the MMWA05P22K-F is the recommended selection. For legacy system maintenance where RoHS compliance is not mandated, either part satisfies functional requirements.

Frequently Asked Questions (FAQ)

Q: Can MMWA05P22K-F replace MMWA05P22K in existing circuits?

A: Yes. The MMWA05P22K-F is electrically and mechanically equivalent. All electrical parameters (capacitance, tolerance, voltage ratings, temperature range) and physical dimensions (axial package, 0.240" Dia x 0.685" L) are identical. Direct substitution on PCBs is possible without circuit modification.

Q: What is the significance of the "-F" suffix in MMWA05P22K-F?

A: The "-F" suffix indicates a variant designation within the MMWA series. In this case, it denotes the active production version with ROHS3 compliance, distinguishing it from the obsolete MMWA05P22K variant.

Q: Are there dimensional differences between these parts?

A: No. Both parts share identical physical dimensions: 0.240" diameter by 0.685" length (6.10mm x 17.40mm). PCB hole spacing and component placement are identical.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance relates to material composition and manufacturing processes, not electrical characteristics. The MMWA05P22K-F maintains identical capacitance, voltage ratings, temperature range, and dielectric properties as the MMWA05P22K.

Q: Can I use MMWA05P22K-F in applications originally designed for MMWA05P22K?

A: Yes. The MMWA05P22K-F is suitable for all applications originally specified for the MMWA05P22K. The active product status and improved regulatory compliance make it the preferred choice for ongoing procurement.

Q: What is the lead spacing for these axial capacitors?

A: Lead spacing information is not provided in the component specifications. Physical measurement or manufacturer datasheet consultation is required for precise lead-to-lead distance.

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

A: Yes. Both parts operate across the temperature range -55°C to 125°C, suitable for industrial and automotive applications requiring extended temperature performance.
