Engineering Selection Recommendations

MPIA4012V2-2R2-R (Eaton - Electronics Division)

This substitute maintains identical inductance, tolerance, and operating temperature specifications as the main part. The MPIA4012V2-2R2-R is an active product with current manufacturing support. Current rating of 2.9 A exceeds the 2.6 A requirement of the original design. DC resistance of 90 mOhm is marginally higher than the 80 mOhm specification but remains within acceptable tolerance for most applications. The part carries AEC-Q200 qualification and RoHS compliance. Physical dimensions increase slightly (4.95mm × 4.20mm), requiring PCB layout verification. This option provides the closest functional equivalence with active product status.

IHLP1616ABER2R2M11 (Vishay Dale)

This substitute provides identical inductance and operating temperature range with matching physical footprint (4.45mm × 4.06mm × 1.20mm). Current rating of 2.75 A and DC resistance of 83.5 mOhm both satisfy the original specification requirements. The part is active with extensive inventory availability (35,400 units). ROHS3 and REACH compliance certifications are provided. Saturation current of 3.0 A is lower than the original 5.9 A specification, requiring evaluation for peak current transient conditions. This option offers dimensional compatibility and active product status.

B82464G4222M000 (EPCOS - TDK Electronics)

This substitute maintains the 2.2 µH inductance and ±20% tolerance with extended operating temperature range (-55°C to 150°C). The part features significantly lower DC resistance (10 mOhm Max) and higher current rating (6.5 A), providing enhanced performance margin. AEC-Q200 qualification and ROHS3 compliance are provided. Physical dimensions are substantially larger (10.40mm × 10.40mm × 4.80mm), requiring significant PCB layout modification. Core material is ferrite rather than metal composite. This option is suitable for applications where increased current capacity and reduced losses are beneficial and space constraints permit the larger footprint.

Frequently Asked Questions (FAQ)

Q: Can the MPIA4012V2-2R2-R be used as a direct replacement for the MPIA4040R1-2R2-R?

A: The MPIA4012V2-2R2-R is functionally compatible for applications requiring 2.2 µH inductance at 2.6 A or less. The higher current rating (2.9 A) and marginally higher DC resistance (90 mOhm vs. 80 mOhm) are acceptable for most designs. Physical dimensions increase from 4.45mm × 4.06mm to 4.95mm × 4.20mm, requiring PCB layout verification to confirm clearance availability.

Q: What is the primary difference between the IHLP1616ABER2R2M11 and the original part?

A: The IHLP1616ABER2R2M11 maintains identical physical footprint and inductance specifications. The primary difference is saturation current: 3.0 A versus 5.9 A in the original part. Applications experiencing peak current transients above 3.0 A require detailed analysis to confirm compatibility.

Q: Why is the B82464G4222M000 significantly larger than the other substitutes?

A: The B82464G4222M000 uses a drum core wirewound construction with ferrite material, compared to the molded metal composite design of the original part. This construction method enables lower DC resistance (10 mOhm) and higher current capacity (6.5 A) but requires a larger physical envelope (10.40mm × 10.40mm × 4.80mm).

Q: Are all substitute parts RoHS compliant?

A: The MPIA4012V2-2R2-R is RoHS Compliant. The IHLP1616ABER2R2M11 and B82464G4222M000 are both ROHS3 Compliant. The original MPIA4040R1-2R2-R RoHS status is not specified in available documentation.

Q: Which substitute part has the lowest DC resistance?

A: The B82464G4222M000 has the lowest DC resistance at 10 mOhm Max, compared to 80-90 mOhm for the other options. Lower DC resistance reduces power dissipation and heat generation in high-current applications.

Q: Can the B82464G4222M000 operate at higher temperatures than the original part?

A: Yes. The B82464G4222M000 operates from -55°C to 150°C, extending the upper temperature limit by 25°C compared to the original part's -55°C to 125°C range.

Q: What is the saturation current specification and why does it matter?

A: Saturation current (Isat) is the DC current level at which the inductor's inductance begins to degrade significantly. The original part saturates at 5.9 A. The IHLP1616ABER2R2M11 saturates at 3.0 A, requiring verification that peak transient currents remain below this threshold to maintain inductance stability.

Q: Are all substitute parts shielded?

A: Yes. All substitute parts maintain shielded construction, matching the original part's electromagnetic interference containment characteristics.

Q: What is MSL 1 and why is it important?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All listed parts, including the original and substitutes, carry MSL 1 classification, eliminating moisture-related handling constraints.
