Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPI4040R2-2R2-R is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Shielding requirement: Shielded
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C minimum
• Inductance test frequency: 100 kHz

Secondary Compatibility Factors:

• Current rating: Minimum 3.2 A (higher ratings acceptable)
• DC resistance: Comparable performance (58 mOhm baseline)
• Saturation current: Minimum 5.7 A (higher ratings acceptable)
• Package footprint: Physical dimensions must accommodate board layout constraints
• Moisture sensitivity: MSL 1 (Unlimited) required

The substitute parts listed maintain the core electrical specifications while offering variations in construction type (drum core wirewound versus molded), core material composition, and DC resistance characteristics. All substitutes operate within the specified temperature range and maintain shielded construction for electromagnetic compatibility.

Engineering Selection Recommendations

MPI4015V2-2R2-R (Eaton - Electronics Division)

This direct manufacturer substitute from Eaton maintains the same inductance value, tolerance, and core construction type as the obsolete MPI4040R2-2R2-R. The part is currently active and available in production quantities. The primary trade-off is a reduced current rating of 2.9 A versus the original 3.2 A, with correspondingly lower saturation current of 4.5 A. DC resistance increases to 78 mOhm maximum. This substitute is suitable for applications where the 2.9 A rating meets circuit requirements. RoHS compliance is confirmed.

IHLP1616BZER2R2M11 (Vishay Dale)

This molded inductor from Vishay Dale provides equivalent inductance and shielding with a current rating of 3.25 A, exceeding the original specification. DC resistance is 68 mOhm maximum. The construction type differs from the original drum core wirewound design. Physical height increases to 2.00 mm from the original 1.50 mm, requiring verification of board layout clearance. ROHS3 compliance and REACH unaffected status are confirmed. High inventory availability supports procurement continuity.

IHLP1616BZER2R2M1A (Vishay Dale)

This variant of the IHLP1616BZ series offers identical electrical specifications to the IHLP1616BZER2R2M11, with current rating of 3.25 A and DC resistance of 68 mOhm maximum. The part includes AEC-Q200 automotive qualification rating. Metal composite core material is specified. Height is 2.00 mm maximum. ROHS3 compliance and REACH unaffected status are confirmed. This option is suitable for applications requiring automotive-grade reliability.

SRP4020TA-2R2M (Bourns Inc.)

This drum core wirewound inductor from Bourns maintains construction similarity to the original MPI4040R2-2R2R while offering the highest current rating of 4.0 A with saturation current of 6.0 A. DC resistance is 61 mOhm maximum. The carbonyl powder core material differs from the original metal composite. Operating temperature range extends to 150°C maximum. AEC-Q200 automotive qualification is included. Physical height is 2.00 mm. ROHS3 compliance and REACH unaffected status are confirmed. This option provides the best current handling capability and extended temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the MPI4015V2-2R2-R be used as a direct replacement for the MPI4040R2-2R2-R?

A: The MPI4015V2-2R2-R maintains the same inductance value, tolerance, shielding, and core construction type. However, the current rating is reduced from 3.2 A to 2.9 A. Substitution is valid only if the circuit design operates at or below 2.9 A continuous current and does not require the original 5.7 A saturation current capability.

Q: What is the impact of increased DC resistance in the substitute parts?

A: The substitute parts exhibit DC resistance values ranging from 61 mOhm to 78 mOhm compared to the original 58 mOhm. This increase results in higher power dissipation and heat generation at equivalent current levels. Circuit thermal analysis is required to confirm acceptable performance in the target application.

Q: Why do some substitutes have a maximum height of 2.00 mm instead of 1.50 mm?

A: The IHLP1616BZER2R2M11, IHLP1616BZER2R2M1A, and SRP4020TA-2R2M parts utilize different construction techniques that result in increased height. Board layout verification is necessary to confirm that the additional 0.50 mm height does not create clearance conflicts with adjacent components or enclosure constraints.

Q: Are all substitute parts RoHS compliant?

A: Yes. The MPI4015V2-2R2-R is RoHS Compliant. The IHLP1616BZER2R2M11, IHLP1616BZER2R2M1A, and SRP4020TA-2R2M are all ROHS3 Compliant. The original MPI4040R2-2R2-R RoHS status is not specified in the available documentation.

Q: Which substitute offers the best current handling capability?

A: The SRP4020TA-2R2M from Bourns provides the highest current rating at 4.0 A continuous with 6.0 A saturation current. This part also offers the lowest DC resistance at 61 mOhm maximum and the widest operating temperature range extending to 150°C.

Q: What is the significance of AEC-Q200 rating on certain substitutes?

A: AEC-Q200 is an automotive industry qualification standard. The IHLP1616BZER2R2M1A and SRP4020TA-2R2M carry this certification, indicating compliance with automotive reliability and environmental stress testing requirements. This qualification is relevant only for applications requiring automotive-grade components.

Q: Can the molded inductor substitutes (IHLP series) be used interchangeably with the drum core wirewound original?

A: The IHLP1616BZER2R2M11 and IHLP1616BZER2R2M1A are molded construction versus the original drum core wirewound design. While electrical specifications are equivalent, the different construction may affect electromagnetic field distribution and coupling characteristics in sensitive circuit topologies. Application-specific validation is required.

Q: What is the difference between IHLP1616BZER2R2M11 and IHLP1616BZER2R2M1A?

A: Both parts share identical electrical specifications and physical dimensions. The primary difference is that IHLP1616BZER2R2M1A includes AEC-Q200 automotive qualification rating and explicitly specifies metal composite core material. Selection depends on whether automotive qualification is required for the target application.

Q: Is the reduced saturation current of the MPI4015V2-2R2-R a limiting factor?

A: The MPI4015V2-2R2-R has saturation current of 4.5 A compared to the original 5.7 A. This reduction limits the maximum current the inductor can handle before core saturation occurs. If the circuit design includes transient current conditions or fault scenarios that exceed 4.5 A, this substitute is not suitable.
