Engineering Selection Recommendations

MPIA4015V2-4R7-R (Eaton - Electronics Division)

This part is the primary substitute for the obsolete MPIA4040R2-4R7-R. Both components are manufactured by Eaton and share identical inductance, current rating, tolerance, and operating temperature specifications. The MPIA4015V2-4R7-R is currently active in production with substantial inventory availability (3595 pcs). DC resistance increases from 105mOhm to 130mOhm maximum, which represents a 23.8% increase in resistive losses. Saturation current decreases from 4.3 A to 3.0 A. The part maintains AEC-Q200 qualification and RoHS compliance. Physical dimensions increase slightly (4.95 x 4.20mm vs. 4.45 x 4.06mm), and height remains at 1.50mm maximum. Self-resonant frequency is specified at 22MHz. This substitute is recommended for applications where the increased DC resistance and reduced saturation current are acceptable within circuit design margins.

IHLP1616BZER4R7M11 (Vishay Dale)

This Vishay Dale inductor provides an alternative from a different manufacturer with identical inductance, tolerance, and operating temperature range. Current rating is reduced to 1.7 A, which is below the main part specification of 2.2 A. Saturation current is 1.75 A. DC resistance matches the main part at 105mOhm maximum. Physical footprint is identical (4.45 x 4.06mm), but height increases to 2.00mm maximum. Self-resonant frequency is 29MHz. The part is ROHS3 compliant and REACH unaffected. This substitute is suitable only for applications with current requirements not exceeding 1.7 A continuous.

B82464G4472M000 (EPCOS - TDK Electronics)

This EPCOS - TDK Electronics inductor differs significantly in construction (drum core wirewound vs. molded) and core material (ferrite vs. metal composite). Inductance, tolerance, and operating temperature range match the main part. Current rating is substantially higher at 4.9 A with saturation current of 5.2 A. DC resistance is significantly lower at 15mOhm maximum, representing a 85.7% reduction in resistive losses. Physical dimensions are substantially larger (10.40 x 10.40mm footprint, 4.80mm height), which may present layout constraints. Self-resonant frequency is 37MHz. The part maintains AEC-Q200 qualification, ROHS3 compliance, and REACH unaffected status. Operating temperature extends to 150°C. This substitute is applicable for applications requiring higher current capacity and lower DC resistance, provided that the larger package footprint is accommodated in the circuit design.

Frequently Asked Questions (FAQ)

Q: Can MPIA4015V2-4R7-R be used as a direct replacement for MPIA4040R2-4R7-R?

A: MPIA4015V2-4R7-R is functionally equivalent for applications where the increased DC resistance (130mOhm vs. 105mOhm) and reduced saturation current (3.0 A vs. 4.3 A) are within acceptable circuit design margins. Both parts share identical inductance (4.7 µH), current rating (2.2 A), tolerance (±20%), operating temperature range (-55°C to 125°C), and AEC-Q200 qualification. Physical dimensions differ slightly, but both maintain 1.50mm maximum height. This part is recommended as the primary substitute due to common manufacturer and active production status.

Q: What are the limitations of IHLP1616BZER4R7M11 as a substitute?

A: The IHLP1616BZER4R7M11 has a reduced current rating of 1.7 A compared to the main part specification of 2.2 A. This part is suitable only for applications where continuous current does not exceed 1.7 A. Saturation current is 1.75 A. All other electrical parameters (inductance, tolerance, operating temperature, DC resistance) are compatible. Physical footprint is identical, but height increases from 1.50mm to 2.00mm maximum.

Q: Why is B82464G4472M000 significantly larger than the other substitutes?

A: B82464G4472M000 uses drum core wirewound construction with ferrite core material, whereas the main part and other substitutes use molded metal composite construction. The larger package (10.40 x 10.40mm footprint, 4.80mm height) accommodates the wirewound design and provides substantially higher current capacity (4.9 A) and lower DC resistance (15mOhm). This part is suitable for applications requiring higher current handling and lower resistive losses, provided that the larger footprint can be accommodated in the circuit layout.

Q: Are all substitute parts RoHS compliant?

A: MPIA4015V2-4R7-R is RoHS compliant. IHLP1616BZER4R7M11 and B82464G4472M000 are both ROHS3 compliant. The main part MPIA4040R2-4R7-R does not specify RoHS status. All parts have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute maintains AEC-Q200 qualification?

A: MPIA4015V2-4R7-R and B82464G4472M000 both maintain AEC-Q200 qualification. IHLP1616BZER4R7M11 does not specify AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, MPIA4015V2-4R7-R is the recommended substitute.

Q: What is the impact of DC resistance differences on circuit performance?

A: DC resistance directly affects resistive losses and heat generation. MPIA4015V2-4R7-R increases DCR from 105mOhm to 130mOhm (23.8% increase). B82464G4472M000 reduces DCR to 15mOhm (85.7% decrease). IHLP1616BZER4R7M11 maintains DCR at 105mOhm. Higher DC resistance increases power dissipation; lower DC resistance reduces losses. Circuit design must account for these differences in thermal and efficiency calculations.

Q: Can self-resonant frequency differences affect circuit operation?

A: Self-resonant frequency (SRF) determines the frequency at which the inductor transitions from inductive to capacitive behavior. The main part does not specify SRF. Substitutes provide SRF values: MPIA4015V2-4R7-R at 22MHz, IHLP1616BZER4R7M11 at 29MHz, and B82464G4472M000 at 37MHz. For applications operating near or above these frequencies, SRF differences may affect impedance characteristics. Verify that circuit operating frequencies remain below the SRF of the selected substitute.
