Substitute Part Grouping Explanation

Substitution eligibility for the MMP2W4P7K-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 4.7 µF (exact match)
• Tolerance: ±10% (exact match)
• Voltage Rating - DC: 250V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 160V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match)

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 Compliant status required
• REACH Unaffected status required

The substitute part 475MWR250K meets all electrical and mechanical equivalence criteria. Operating temperature range variation does not disqualify substitution when the substitute range remains within acceptable limits for the application circuit.

Engineering Selection Recommendations

Primary Selection: MMP2W4P7K-F

The MMP2W4P7K-F remains the preferred component when available. This part offers the widest operating temperature range (-55°C ~ 125°C), providing maximum thermal margin for applications subject to extreme environmental conditions. Active product status and 966 units in current inventory ensure supply continuity. ROHS3 compliance and REACH Unaffected status satisfy regulatory requirements for commercial and industrial deployment.

Substitute Selection: 475MWR250K

The 475MWR250K qualifies as a direct electrical substitute when MMP2W4P7K-F availability is constrained. This part maintains identical capacitance, tolerance, voltage ratings, and dielectric composition. Both components are manufactured within the Cornell Dubilier family, ensuring consistent quality standards. The 475MWR250K operates within the narrower temperature range of -40°C ~ 105°C; this substitution is valid for applications where circuit operation remains within these bounds.

Physical Dimension Consideration:

The 475MWR250K exhibits smaller physical dimensions (19.50mm diameter x 34.00mm length) compared to the MMP2W4P7K-F (25.00mm x 16.00mm x 43.00mm). PCB layout verification is required to confirm that the substitute component fits within available mounting space and maintains adequate clearance from adjacent components.

Frequently Asked Questions (FAQ)

Q: Can 475MWR250K replace MMP2W4P7K-F in all applications?

A: Electrical substitution is valid when circuit operating temperature remains within -40°C ~ 105°C. The MMP2W4P7K-F supports extended temperature operation to -55°C and 125°C. Verify application temperature requirements before substitution.

Q: Are there physical mounting differences between these parts?

A: Both components use axial through-hole mounting with PC pin termination. However, physical dimensions differ: MMP2W4P7K-F measures 25.00mm x 16.00mm x 43.00mm, while 475MWR250K measures 19.50mm diameter x 34.00mm length. Confirm PCB layout accommodates the substitute component's smaller profile.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both MMP2W4P7K-F and 475MWR250K are ROHS3 Compliant and REACH Unaffected, satisfying equivalent regulatory requirements for commercial and industrial applications.

Q: What is the tolerance specification for these capacitors?

A: Both parts carry ±10% capacitance tolerance. This tolerance applies across the specified operating temperature range and voltage conditions.

Q: Are voltage ratings identical between the two parts?

A: Yes. Both components are rated 250V DC and 160V AC. Voltage ratings are equivalent and interchangeable for circuit design purposes.

Q: What dielectric material is used in these capacitors?

A: Both parts utilize polyester metallized dielectric construction, providing stable capacitance performance and long operational life in general-purpose applications.
