Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMWA05P1K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.1 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 ~ 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical Dimensions: 0.220" Dia x 0.563" L (exact match required)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical compatibility within the original circuit design.

Parameter Comparison

Engineering Selection Recommendations

The MMWA05P1K-F serves as the direct substitute for the obsolete MMWA05P1K. Both parts are manufactured by Cornell Dubilier Electronics within the same MMWA series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between the main part and its substitute is product status and regulatory compliance. The MMWA05P1K is classified as obsolete, whereas the MMWA05P1K-F maintains active production status. Additionally, the MMWA05P1K-F achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

For new designs or component replenishment, the MMWA05P1K-F is the appropriate selection due to its active availability and enhanced regulatory compliance posture. Existing circuit designs utilizing the MMWA05P1K may be directly updated to incorporate the MMWA05P1K-F without modification to PCB layout, schematic design, or functional performance parameters.

Frequently Asked Questions (FAQ)

Q: Can the MMWA05P1K-F be used as a direct replacement for the MMWA05P1K?

A: Yes. The MMWA05P1K-F is electrically and mechanically equivalent to the MMWA05P1K across all specified parameters, including capacitance, voltage rating, dielectric material, operating temperature range, package dimensions, and termination type. No circuit modifications are required.

Q: What is the primary reason for substituting the MMWA05P1K?

A: The MMWA05P1K is classified as obsolete. The MMWA05P1K-F provides equivalent functionality with active production status and ROHS3 compliance, ensuring long-term component availability and regulatory alignment.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both the MMWA05P1K and MMWA05P1K-F share identical axial package dimensions of 0.220" diameter by 0.563" length (5.60mm x 14.30mm). PCB layout and mounting hole spacing remain unchanged.

Q: Does the MMWA05P1K-F meet RoHS requirements?

A: Yes. The MMWA05P1K-F is ROHS3 compliant. The original MMWA05P1K is RoHS non-compliant. For applications subject to RoHS directives, the MMWA05P1K-F is the required selection.

Q: Are there any electrical performance differences between the substitute and the original part?

A: No. Both parts maintain identical capacitance (0.1 µF), tolerance (±10%), voltage ratings (50V DC / 35V AC), dielectric material (polyester metallized), and operating temperature range (-55°C ~ 125°C).
