MMP1P47K-F Equivalent & Substitute Parts Reference

Part Overview

The MMP1P47K-F is a 0.47 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the MMP series. This through-hole axial component operates at 100V DC with polyester metallized dielectric construction and ±10% capacitance tolerance. The part is Active status with 693 units in current inventory stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges. Alternative sources may be required due to inventory availability, lead time constraints, or procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMP1P47K-F is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.47 µF
• Capacitance tolerance: ±10%
• Voltage rating - DC: 100V minimum
• Dielectric material: Polyester, Metallized
• Mounting type: Through Hole
• Package type: Axial
• Termination: PC Pins

Allowable Variation Parameters:

• Operating temperature range may differ (substitute must cover application requirements)
• Physical dimensions may vary within axial form factor constraints
• Voltage rating - AC may differ (not primary selection criterion)
• ESR and other performance characteristics may differ

The substitute part 474MWR100K meets all mandatory matching criteria and is classified as a direct equivalent for the MMP1P47K-F.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The MMP1P47K-F remains the preferred selection when:

• Operating temperature range of -55°C to 125°C is required
• Physical space accommodates the larger axial form factor (23.00mm length)
• Original equipment manufacturer (OEM) specification calls for MMP series

Substitute Selection Criteria:

The 474MWR100K is electrically and functionally equivalent when:

• Operating temperature range of -40°C to 105°C satisfies application requirements
• Physical space constraints require the more compact form factor (15.50mm length)
• Procurement lead time or inventory availability favors the MWR series
• AC voltage rating of 63V is sufficient for the application

Both parts are Active status products with current manufacturing support and full RoHS3 compliance. Both maintain MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected regulatory status.

Frequently Asked Questions (FAQ)

Q: Can 474MWR100K be used as a direct replacement for MMP1P47K-F in all applications?

A: The 474MWR100K is electrically equivalent for DC voltage and capacitance specifications. However, the operating temperature range is narrower (-40°C to 105°C versus -55°C to 125°C). Verify that your application does not require operation below -40°C or above 105°C. Physical dimensions differ significantly; confirm PCB layout accommodates the smaller 15.50mm length.

Q: What is the primary difference between these two parts?

A: Both parts share identical capacitance (0.47 µF), tolerance (±10%), DC voltage rating (100V), dielectric material (polyester metallized), and mounting configuration (through-hole axial). The MMP1P47K-F operates across a wider temperature range (-55°C to 125°C) and has a larger physical form factor. The 474MWR100K is more compact and operates within -40°C to 105°C.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) rating. Both are Active status products with current manufacturing support.

Q: Does the physical size difference affect electrical performance?

A: Physical dimensions do not affect the core electrical specifications (capacitance, voltage rating, tolerance, or dielectric properties). Size differences impact only PCB layout compatibility and mounting space requirements.

Q: Which part should I select for new designs?

A: For new designs, select based on application requirements: choose MMP1P47K-F if the full -55°C to 125°C temperature range is needed; choose 474MWR100K if space constraints favor the compact form factor and the narrower temperature range is acceptable.
