Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMP4S47K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.047 µF (exact match required)
• Voltage Rating - DC: 400V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 200V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (material type must match)
• Tolerance: ±10% (tolerance band must be equal or tighter)
• Operating Temperature Range: -55°C to 125°C (must encompass or exceed this range)
• Mounting Type: Through Hole (physical mounting compatibility)
• Package / Case: Axial (form factor must match)
• Termination: PC Pins (lead configuration must match)

Substitute parts must satisfy all parameters listed above. The MMP4S47K-F variant from Cornell Dubilier Electronics meets these criteria and represents the direct active equivalent.

Frequently Asked Questions (FAQ)

Q: Can the MMP4S47K-F be used as a direct replacement for the MMP4S47K?

A: Yes. The MMP4S47K-F meets all electrical and mechanical parameters required for direct substitution. Both parts share identical capacitance (0.047 µF), voltage ratings (400V DC / 200V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), and physical dimensions (10.00mm × 6.00mm × 17.00mm). The axial through-hole mounting and PC pin termination are identical, enabling direct board-level replacement without circuit modification.

Q: What is the significance of the product status difference between MMP4S47K and MMP4S47K-F?

A: The MMP4S47K is classified as obsolete, indicating discontinued manufacturing and limited remaining inventory. The MMP4S47K-F maintains active product status, ensuring reliable long-term procurement availability. For new designs or ongoing production, the active MMP4S47K-F is the appropriate selection.

Q: Does the RoHS3 compliance of MMP4S47K-F affect electrical performance?

A: No. RoHS3 compliance reflects manufacturing process and material composition standards but does not alter the electrical characteristics of the capacitor. The MMP4S47K-F delivers identical capacitance, voltage rating, and temperature performance as the original MMP4S47K.

Q: Are there any physical installation differences between these parts?

A: No. Both parts feature identical axial package dimensions (10.00mm × 6.00mm × 17.00mm) and PC pin termination. PCB footprints, lead spacing, and mounting hole requirements are identical, eliminating any installation or layout modifications.

Q: What inventory status should influence procurement decisions?

A: The MMP4S47K has 1,085 pieces in stock but is obsolete. The MMP4S47K-F has 992 pieces in stock and active status. For new procurement, the MMP4S47K-F is the appropriate choice due to ongoing manufacturing support and regulatory compliance.
