Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP2-4R7-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 4.7 µH (±20% tolerance acceptable)
• Inductance test frequency: 100 kHz
• Mounting type: Surface Mount
• Physical footprint compatibility: 7.50mm L × 5.20mm W maximum

Secondary Compatibility Factors:

• Current rating must equal or exceed 1.18 A
• DC resistance must not exceed 180mOhm (lower values acceptable)
• Operating temperature range must encompass -40°C to 85°C minimum
• Core material and shielding configuration affect EMI performance but do not prevent functional substitution when electrical parameters are met

Two substitute parts meet these criteria with varying performance characteristics and availability status.

Parameter Comparison

Engineering Selection Recommendations

MP2A-4R7-R (Eaton - Electronics Division):

This substitute offers direct compatibility with the MP2-4R7-R in terms of physical footprint and operating temperature range. The MP2A-4R7-R provides improved current handling (1.6 A versus 1.18 A) and reduced DC resistance (117 mOhm versus 180 mOhm maximum), resulting in lower power dissipation. The part is manufactured by the same supplier and maintains the same inductance value and tolerance. Active product status ensures ongoing availability. The core material differs (Molybdenum Permalloy versus Ferrite), which may affect frequency response characteristics but does not prevent functional substitution. RoHS compliance status is confirmed.

MPLCG0630L4R7 (KEMET):

This substitute provides the highest current rating (5.5 A) and lowest DC resistance (41 mOhm), making it suitable for applications requiring enhanced thermal performance and current capacity. The shielded configuration reduces electromagnetic interference compared to the unshielded main part. The extended operating temperature range (-40°C to 125°C) accommodates more demanding thermal environments. Physical dimensions differ slightly in width (6.70mm versus 5.20mm) and height (3.00mm versus 1.80mm), requiring verification of PCB layout compatibility. Active product status and ROHS3 compliance are confirmed. The metal composite core material provides distinct frequency response characteristics.

Selection Basis:

• Both substitutes maintain the 4.7 µH inductance specification and ±20% tolerance
• Both support surface mount assembly with 100 kHz test frequency compatibility
• Current ratings of both substitutes exceed the 1.18 A requirement
• DC resistance values of both substitutes are lower than the 180 mOhm maximum
• Operating temperature ranges of both substitutes encompass the -40°C to 85°C requirement
• Both substitutes carry active product status, ensuring procurement viability
• Compliance certifications (RoHS/ROHS3) are documented for both alternatives

Frequently Asked Questions (FAQ)

Q: Can MP2A-4R7-R directly replace MP2-4R7-R without PCB modifications?

A: Yes. The MP2A-4R7-R maintains identical physical dimensions (7.50mm × 5.20mm × 1.80mm) and mounting type, enabling direct PCB substitution without layout changes. The inductance value, tolerance, and test frequency are identical.

Q: What is the primary difference between MP2A-4R7-R and MPLCG0630L4R7?

A: The MPLCG0630L4R7 has larger physical dimensions (7.50mm × 6.70mm × 3.00mm) and different core material (metal composite versus molybdenum permalloy). It provides significantly higher current capacity (5.5 A) and lower DC resistance (41 mOhm). PCB layout verification is required before substitution.

Q: Does shielding affect the choice between unshielded and shielded substitutes?

A: Shielding configuration affects electromagnetic interference performance. The MPLCG0630L4R7 is shielded, while MP2-4R7-R and MP2A-4R7-R are unshielded. Selection depends on circuit EMI requirements. Shielded inductors reduce radiated emissions but may increase cost and physical footprint.

Q: Are both substitutes RoHS compliant?

A: Yes. MP2A-4R7-R is RoHS Compliant, and MPLCG0630L4R7 is ROHS3 Compliant. Both meet current environmental regulations.

Q: What is the impact of different core materials on circuit performance?

A: Core material affects frequency response, Q factor, and saturation characteristics. Ferrite (original), Molybdenum Permalloy (MP2A-4R7-R), and Metal Composite (MPLCG0630L4R7) cores exhibit different performance across frequency ranges. Electrical parameters (inductance, current rating, DCR) remain compatible for direct substitution.

Q: Can MPLCG0630L4R7 be used in space-constrained applications?

A: No. The MPLCG0630L4R7 exceeds the original footprint in width (6.70mm versus 5.20mm) and height (3.00mm versus 1.80mm). PCB layout compatibility must be verified before selection. MP2A-4R7-R maintains the original dimensions.

Q: What is the significance of the current saturation (Isat) rating?

A: Isat indicates the current level at which the inductor begins to lose inductance due to core saturation. All substitutes have Isat values exceeding the 1.18 A operating requirement, ensuring stable inductance across the specified current range.

Q: Are packaging formats interchangeable?

A: MP2A-4R7-R and MPLCG0630L4R7 are supplied in Tape & Reel (TR) format, suitable for automated assembly. Verify that assembly equipment supports TR packaging before procurement.
