MMP4S47K-F Equivalent & Substitute Parts

Part Overview

The MMP4S47K-F is a 0.047 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 400V DC operation with polyester metallized dielectric construction. This axial through-hole component is designed for general-purpose applications requiring stable capacitance performance across extended temperature ranges (-55°C to 125°C). The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility requirements are met within the same product category.

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

• Capacitance value: 0.047 µF (exact match)
• Capacitance tolerance: ±10% (exact match)
• Voltage rating - DC: 400V (minimum requirement; higher ratings acceptable)
• Voltage rating - AC: 200V (minimum requirement; higher ratings acceptable)
• Dielectric material: Polyester, Metallized (exact match)
• Operating temperature range: -55°C to 125°C (exact match or wider range acceptable)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match)
• Package / Case: Axial (exact match)
• Termination: PC Pins (exact match)

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

The substitute part 150473K400DB meets all electrical and mechanical equivalence criteria. Physical dimensions differ within acceptable tolerances for axial film capacitors, and both parts share identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MMP4S47K-F and 150473K400DB are Active product status components manufactured by Cornell Dubilier Electronics with full ROHS3 compliance and REACH Unaffected status. Selection between these parts is based on the following engineering criteria:

MMP4S47K-F Selection Criteria:

• Applications requiring the specific physical envelope of 10.00mm diameter x 17.00mm length
• PCB layouts with spatial constraints matching the larger axial form factor
• Inventory availability: 992 pieces in stock

150473K400DB Selection Criteria:

• Applications where the smaller physical envelope of 7.00mm diameter x 16.50mm length provides design advantage
• PCB layouts with tighter spatial constraints
• Higher inventory availability: 2,057 pieces in stock
• Bulk packaging configuration

Both parts deliver identical electrical performance and thermal characteristics across the specified operating range. Physical dimension differences do not affect electrical substitution eligibility when PCB layout accommodates the alternative form factor.

Frequently Asked Questions (FAQ)

Q: Can 150473K400DB replace MMP4S47K-F in existing designs?

A: Yes, provided PCB layout accommodates the different physical dimensions. The 150473K400DB has a smaller diameter (7.00mm vs. 10.00mm) and slightly shorter length (16.50mm vs. 17.00mm). All electrical parameters, voltage ratings, capacitance values, and operating temperature ranges are identical.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical capacitance (0.047 µF), tolerance (±10%), voltage ratings (400V DC / 200V AC), dielectric material (polyester metallized), and operating temperature range (-55°C to 125°C).

Q: What is the significance of the different series designations (MMP vs. 150)?

A: Series designation reflects internal CDE product line organization. Both series employ identical electrical specifications and construction methods for this capacitance and voltage rating combination.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MMP4S47K-F and 150473K400DB are ROHS3 compliant, REACH Unaffected, and carry MSL rating of 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8532.25.0060.

Q: Which part should be selected for new designs?

A: Selection depends on PCB layout requirements. The 150473K400DB offers space savings with its smaller form factor and higher inventory availability. The MMP4S47K-F maintains the original design envelope if required for existing board layouts.

Q: Are there lead spacing differences between these parts?

A: Lead spacing data is not provided in the component specifications for either part. Physical dimensions should be verified against PCB footprint requirements before final selection.
