MMP6S47K Equivalent & Substitute Parts

Part Overview

The MMP6S47K is a 0.047 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 630V DC operation with polyester metallized dielectric construction. This component is classified as obsolete, indicating discontinued production and limited availability in the original specification. Identification of equivalent substitute parts is necessary to maintain design continuity and ensure component procurement for new production runs or field replacements where the original part number is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMP6S47K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.047 µF
• DC voltage rating: 630V minimum
• AC voltage rating: 250V minimum
• Tolerance: ±10%
• Dielectric material: Polyester, Metallized

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Axial
• Physical dimensions: 0.394" W, 0.236" T x 0.906" L (10.00mm, 6.00mm x 23.00mm)
• Termination style: PC Pins

Environmental Parameters:

• Operating temperature range: -55°C ~ 125°C

Substitute parts must match all electrical and mechanical parameters without deviation. Compliance certifications and product status may differ between the original and substitute part, but do not affect functional equivalence.

Engineering Selection Recommendations

MMP6S47K-F is the direct substitute for the obsolete MMP6S47K. Both components are manufactured by Cornell Dubilier Electronics and share identical electrical and mechanical specifications. The MMP6S47K-F is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary distinction between the original and substitute part is compliance certification. The MMP6S47K-F carries ROHS3 compliance, whereas the MMP6S47K is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the MMP6S47K-F is the appropriate selection. For legacy systems or applications without RoHS mandates, both parts are functionally equivalent.

The part number 150473J630EC is listed as an additional substitute reference but lacks complete technical specification data in the provided input. Verification of this part number against the established electrical and mechanical parameters is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the MMP6S47K-F be used as a direct replacement for the MMP6S47K?

A: Yes. The MMP6S47K-F is a direct substitute. Both components have identical capacitance (0.047 µF), voltage ratings (630V DC / 250V AC), dielectric material (polyester metallized), tolerance (±10%), operating temperature range (-55°C ~ 125°C), and physical dimensions (10.00mm x 6.00mm x 23.00mm). The axial through-hole mounting configuration and PC pin termination are identical.

Q: What is the difference between MMP6S47K and MMP6S47K-F?

A: The MMP6S47K-F is the active production equivalent of the obsolete MMP6S47K. The functional electrical and mechanical specifications are identical. The MMP6S47K-F carries ROHS3 compliance certification, while the original MMP6S47K is RoHS non-compliant. The MMP6S47K-F is currently in active production with confirmed inventory availability.

Q: Are there any physical dimension differences between substitute parts?

A: No. All substitute parts maintain the same physical dimensions of 0.394" W, 0.236" T x 0.906" L (10.00mm, 6.00mm x 23.00mm) in axial package configuration. PCB layout and mounting hole spacing remain unchanged.

Q: Does the RoHS3 compliance of MMP6S47K-F affect circuit performance?

A: No. RoHS3 compliance is a regulatory and material composition certification that does not alter electrical performance or operating characteristics. The component functions identically in all circuit applications.

Q: What is the tolerance specification for this capacitor?

A: The tolerance is ±10% for both the original MMP6S47K and substitute MMP6S47K-F. This tolerance applies to the 0.047 µF capacitance value.

Q: Can this capacitor be used in AC applications?

A: Yes. The component is rated for 250V AC operation. The 630V DC rating provides additional margin for AC applications within the specified voltage limit.

Q: What is the operating temperature range?

A: The operating temperature range is -55°C to 125°C for both the original and substitute parts. This range applies to all electrical and mechanical specifications.
