Substitute Part Grouping Explanation

Substitute parts for the MMP2W1K are identified based on strict electrical and mechanical parameter matching within the Cornell Dubilier Electronics MMP series. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Capacitance: 1 µF
• Tolerance: ±10%
• Voltage Rating - DC: 250V
• Voltage Rating - AC: 160V
• Dielectric Material: Polyester, Metallized

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package / Case: Axial
• Physical Dimensions: 13.50mm W × 7.50mm T × 28.00mm L
• Termination: PC Pins

Environmental Parameters (Must Match Exactly):

• Operating Temperature Range: -55°C to 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as direct substitutes. Variations in product status, packaging format, or compliance certifications do not affect functional substitutability when all electrical and mechanical parameters align.

Engineering Selection Recommendations

The MMP2W1K-F serves as the direct functional equivalent to the obsolete MMP2W1K. Both components share identical electrical specifications, mechanical dimensions, and environmental operating parameters, ensuring pin-for-pin and form-factor compatibility in through-hole circuit board applications.

The MMP2W1K-F maintains active product status within the Cornell Dubilier Electronics catalog, providing assured long-term availability for procurement and supply chain continuity. The MMP2W1K-F additionally carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution in restricted substance environments.

Selection between these parts depends on application requirements regarding regulatory compliance. For applications where RoHS3 compliance is mandatory, the MMP2W1K-F is the required selection. For legacy systems or applications without compliance requirements, either part satisfies the functional specification.

Frequently Asked Questions (FAQ)

Q: Can MMP2W1K-F replace MMP2W1K in existing circuit designs?

A: Yes. The MMP2W1K-F is a direct substitute. Both components have identical capacitance (1 µF), tolerance (±10%), voltage ratings (250V DC / 160V AC), dielectric material (polyester, metallized), physical dimensions (13.50mm × 7.50mm × 28.00mm), and axial through-hole mounting configuration. No circuit modifications are required.

Q: What is the difference between MMP2W1K and MMP2W1K-F?

A: The primary differences are product status and compliance certification. MMP2W1K is obsolete and RoHS non-compliant. MMP2W1K-F is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Does the packaging format affect substitutability?

A: No. MMP2W1K is supplied in standard packaging, while MMP2W1K-F is supplied in bulk packaging. Packaging format does not affect component functionality or circuit board compatibility. The physical component dimensions and electrical characteristics remain unchanged.

Q: Are there any temperature or voltage derating considerations when substituting these parts?

A: No. Both components operate identically across the -55°C to 125°C temperature range with 250V DC and 160V AC voltage ratings. No derating adjustments are necessary.

Q: What does Moisture Sensitivity Level 1 mean for these capacitors?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. These components do not require special humidity-controlled storage or handling procedures.
