Substitute Part Grouping Explanation

Substitution of the MMWA05P33K is determined by the following critical electrical and mechanical parameters:

• Capacitance Value: 0.33 µF (exact match required)
• Voltage Rating: Minimum 50V DC and 35V AC
• Dielectric Type: Polyester, Metallized
• Tolerance: ±10%
• Package: Axial through-hole configuration
• Physical Dimensions: 0.280" Dia x 0.685" L (7.10mm x 17.40mm)
• Temperature Range: -55°C to 125°C

The substitute part MMWA05P33K-F maintains identical electrical characteristics and physical specifications while offering improved compliance status and current availability.

Parameter Comparison

Engineering Selection Recommendations

The MMWA05P33K-F is the direct substitute for the obsolete MMWA05P33K. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical specifications and physical dimensions. The primary differentiators are product status and compliance certification:

• The MMWA05P33K-F maintains active production status, ensuring long-term availability.
• The MMWA05P33K-F is RoHS3 compliant, meeting current environmental and regulatory requirements.
• Both parts are REACH unaffected and carry EAR99 ECCN classification.

For new designs or production requiring this capacitor specification, the MMWA05P33K-F is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the MMWA05P33K-F directly replace the MMWA05P33K in existing designs?

A: Yes. The MMWA05P33K-F is electrically and mechanically identical to the MMWA05P33K. Both components have the same capacitance value (0.33 µF), voltage ratings (50V DC / 35V AC), tolerance (±10%), physical dimensions (0.280" Dia x 0.685" L), and operating temperature range (-55°C to 125°C).

Q: What is the significance of the product status difference between these parts?

A: The MMWA05P33K is obsolete and no longer in production. The MMWA05P33K-F is actively manufactured, providing supply continuity and longer availability for future needs.

Q: Does RoHS compliance affect functional compatibility?

A: RoHS compliance indicates adherence to hazardous substance restrictions and does not alter the electrical performance or functional compatibility of the component. The MMWA05P33K-F's RoHS3 compliance demonstrates conformance to current environmental standards.

Q: Are there any PCB layout or spacing considerations between the original and substitute?

A: No. Both parts share identical physical dimensions and axial package configuration. PCB footprints and lead spacing remain the same, requiring no layout modifications.

Q: Is the 334MWR050K an acceptable alternative?

A: The 334MWR050K is listed as an alternative. Functional compatibility requires verification of identical capacitance value, voltage ratings, dielectric type, and physical dimensions against your specific circuit requirements.
