MPIA4040R4-2R2-R Equivalent & Substitute Parts

Part Overview

The MPIA4040R4-2R2-R is a 2.2 µH shielded molded inductor manufactured by Eaton - Electronics Division, rated for 3.9 A continuous current with 35mOhm DC resistance. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement. The part operates across the industrial temperature range of -55°C to 125°C and meets AEC-Q200 reliability standards. Substitute parts must maintain the same inductance value, shielding characteristics, and thermal operating range while accommodating variations in current rating, DC resistance, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPIA4040R4-2R2-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Shielding: Shielded construction required
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C minimum
• Moisture sensitivity level: MSL 1 (Unlimited)

Secondary Compatibility Factors:

• Current rating: Minimum 3.9 A (or higher for derating applications)
• DC resistance: Baseline 35mOhm (variations acceptable based on thermal and power dissipation requirements)
• Saturation current: Minimum 5.7 A (or higher for margin)

The substitute parts listed maintain identical inductance specifications and operating temperature ranges. Variations in current rating, DC resistance, and physical dimensions are acceptable provided the substitute part meets or exceeds the minimum current and saturation requirements for the application circuit.

Engineering Selection Recommendations

MPIA4020V2-2R2-R (Eaton - Electronics Division)

This part is the primary substitute for the MPIA4040R4-2R2-R. Both components are manufactured by Eaton - Electronics Division within the same product family (MPIA40 series). The MPIA4020V2-2R2-R is active in production and meets all critical electrical parameters: identical 2.2 µH inductance, ±20% tolerance, shielded construction, and -55°C to 125°C operating range. Current rating of 3.8 A is marginally lower than the original 3.9 A, and DC resistance increases from 35mOhm to 48mOhm maximum. The part is RoHS compliant and AEC-Q200 rated. Physical dimensions increase slightly (4.95 x 4.20mm versus 4.45 x 4.06mm), requiring PCB layout verification. This substitute is recommended for direct replacement in most applications.

IHLP1616ABER2R2M11 (Vishay Dale)

This part maintains identical physical footprint (4.45 x 4.06mm) and inductance specifications as the original MPIA4040R4-2R2-R. The Vishay Dale IHLP-1616AB-11 series is active and ROHS3 compliant. However, the current rating of 2.75 A falls below the original 3.9 A specification, and saturation current is 3.0 A versus 5.7 A. DC resistance increases significantly to 83.5mOhm maximum. This part is suitable only for applications with reduced current requirements or where lower saturation current is acceptable. Height is reduced to 1.20mm, providing board space advantage. Selection requires circuit analysis to confirm current derating is acceptable.

B82464G4222M000 (EPCOS - TDK Electronics)

This part offers the highest current rating (6.5 A) and lowest DC resistance (10mOhm maximum) among substitutes, with superior saturation current (7.0 A). The component is active, AEC-Q200 rated, and ROHS3 compliant with extended operating temperature to 150°C. However, physical dimensions are significantly larger (10.40 x 10.40mm footprint, 4.80mm height), requiring substantial PCB redesign. The drum core, wirewound construction differs from the molded type of the original part. This substitute is appropriate for applications requiring higher current capacity and lower losses, provided PCB layout accommodates the larger package.

Frequently Asked Questions (FAQ)

Q: Can the MPIA4020V2-2R2-R directly replace the MPIA4040R4-2R2-R without circuit modification?

A: The MPIA4020V2-2R2-R is electrically compatible for most applications. Both parts share identical inductance (2.2 µH), tolerance (±20%), shielding, and operating temperature range. The 3.8 A current rating is marginally lower than 3.9 A, and DC resistance increases from 35mOhm to 48mOhm maximum. PCB layout must accommodate the slightly larger footprint (4.95 x 4.20mm versus 4.45 x 4.06mm). Verify that circuit current does not exceed 3.8 A and that increased DC resistance does not cause unacceptable power dissipation.

Q: What are the limitations of the IHLP1616ABER2R2M11 as a substitute?

A: The IHLP1616ABER2R2M11 has a reduced current rating of 2.75 A compared to the original 3.9 A, and saturation current is only 3.0 A versus 5.7 A. DC resistance is significantly higher at 83.5mOhm maximum. This part is suitable only for circuits operating at reduced current levels. The advantage is identical footprint (4.45 x 4.06mm) and reduced height (1.20mm). Use this substitute only after confirming that circuit current requirements do not exceed 2.75 A continuous operation.

Q: Is the B82464G4222M000 suitable for high-current applications?

A: Yes, the B82464G4222M000 provides the highest current capacity (6.5 A) and lowest DC resistance (10mOhm) among available substitutes. Saturation current is 7.0 A, providing margin above the original 5.7 A specification. The part is AEC-Q200 rated and operates to 150°C. The significant drawback is the larger package size (10.40 x 10.40mm footprint, 4.80mm height), which requires PCB redesign. This substitute is recommended for applications where increased current handling and reduced losses justify the layout changes.

Q: Do all substitute parts meet the same reliability standards as the original MPIA4040R4-2R2-R?

A: The MPIA4020V2-2R2-R and B82464G4222M000 are both AEC-Q200 rated, matching the original part. The IHLP1616ABER2R2M11 does not list AEC-Q200 certification. All three substitutes operate across the -55°C to 125°C range (B82464G4222M000 extends to 150°C) and have MSL 1 (Unlimited) moisture sensitivity. RoHS compliance is confirmed for all active substitutes.

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

A: DC resistance directly affects power dissipation and voltage drop across the inductor. The MPIA4020V2-2R2-R increases DCR from 35mOhm to 48mOhm (37% increase), while the IHLP1616ABER2R2M11 increases to 83.5mOhm (138% increase). The B82464G4222M000 reduces DCR to 10mOhm (71% decrease). Calculate power dissipation using P = I²R for your circuit's operating current to determine if the change is acceptable. Higher DCR increases heat generation; lower DCR reduces losses.

Q: Are there package size constraints that affect substitution?

A: Yes. The MPIA4040R4-2R2-R and IHLP1616ABER2R2M11 share identical footprint (4.45 x 4.06mm) and height (2.00mm and 1.20mm respectively), allowing direct PCB placement. The MPIA4020V2-2R2-R footprint increases to 4.95 x 4.20mm with identical height (2.00mm), requiring minor layout adjustment. The B82464G4222M000 footprint is substantially larger at 10.40 x 10.40mm with 4.80mm height, necessitating significant PCB redesign. Verify available board space before selecting a substitute.

Q: What is the self-resonant frequency, and why does it matter?

A: Self-resonant frequency (SRF) is the frequency at which the inductor's parasitic capacitance resonates with its inductance, causing the impedance to peak. The MPIA4020V2-2R2-R has SRF of 33 MHz, IHLP1616ABER2R2M11 has 49 MHz, and B82464G4222M000 has 72 MHz. The original part does not specify SRF. Higher SRF indicates better high-frequency performance. For circuits operating near or above the SRF, select a substitute with higher SRF to maintain stable inductor behavior.
