Substitute Part Grouping Explanation

Substitution eligibility for the MPIA4040R4-R22-R is determined by the following core parameters: inductance value (220 nH), inductance tolerance (±20%), shielding requirement (shielded), operating temperature range (-55°C to 125°C), and surface mount configuration. The substitute parts identified maintain these critical electrical and mechanical specifications while offering active product status and improved availability.

The three substitute parts are grouped as follows:

MPIA4020V2-R22-R (Eaton - Electronics Division): Active product with identical inductance, tolerance, shielding, and temperature range. Rated for higher continuous current (13 A) and saturation current (17 A) compared to the main part, with slightly elevated DCR (6.6 mOhm). Represents a direct manufacturer upgrade within the same product family.

IHLP1616ABERR22M01 (Vishay Dale): Active product with identical inductance, tolerance, shielding, and temperature range. Rated for lower continuous current (8.5 A) but higher saturation current (20 A). DCR is elevated at 12 mOhm. Provides cross-manufacturer compatibility with ROHS3 compliance.

SRP1265A-R22M (Bourns Inc.): Active product with identical inductance, tolerance, shielding, and AEC-Q200 qualification. Significantly higher current rating (53 A) and saturation current (112 A) with substantially lower DCR (0.6 mOhm). Extended temperature range (-40°C to 150°C). Different core material (carbonyl powder) and construction type (drum core, wirewound). Larger physical footprint.

Parameter Comparison

Engineering Selection Recommendations

MPIA4020V2-R22-R is the primary recommended substitute. This part maintains identical electrical specifications (220 nH inductance, ±20% tolerance, shielded configuration, -55°C to 125°C operating range) and is manufactured by the same supplier as the obsolete MPIA4040R4-R22-R. The MPIA4020V2-R22-R carries active product status with higher current capacity (13 A versus 10.1 A) and improved saturation performance (17 A versus 15 A), providing enhanced design margin. Both parts carry AEC-Q200 qualification. The MPIA4020V2-R22-R is RoHS compliant and available in higher inventory quantities (1478 pcs). Physical dimensions are comparable with minimal footprint increase (4.95mm x 4.20mm versus 4.45mm x 4.06mm).

IHLP1616ABERR22M01 provides cross-manufacturer substitution from Vishay Dale. This part maintains the core electrical parameters (220 nH, ±20% tolerance, shielded, -55°C to 125°C) and identical physical footprint (4.45mm x 4.06mm). However, the continuous current rating (8.5 A) falls below the original specification (10.1 A), making this option suitable only for applications where the actual operating current does not exceed 8.5 A. The part carries ROHS3 compliance and offers the lowest profile height (1.20mm). Extensive inventory availability (17100 pcs) supports procurement continuity.

SRP1265A-R22M from Bourns Inc. is suitable for applications requiring significantly higher current capacity and lower DC resistance. This part maintains the 220 nH inductance value, ±20% tolerance, shielded configuration, and AEC-Q200 qualification. The substantially higher current rating (53 A) and saturation current (112 A) with minimal DCR (0.6 mOhm) address high-current applications. The extended temperature range (-40°C to 150°C) supports broader environmental requirements. However, the significantly larger physical footprint (13.50mm x 12.50mm) and height (6.40mm) require PCB layout redesign and are incompatible with space-constrained applications. Selection of this part is appropriate only when the design can accommodate the larger package and benefits from the superior current-handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can MPIA4020V2-R22-R directly replace MPIA4040R4-R22-R without circuit modification?

A: Yes, for applications where the operating current does not exceed 10.1 A. The MPIA4020V2-R22-R maintains identical inductance (220 nH), tolerance (±20%), shielding, and operating temperature range. The higher current rating (13 A) and saturation current (17 A) provide additional design margin. Physical dimensions are comparable (4.95mm x 4.20mm versus 4.45mm x 4.06mm), and both parts carry AEC-Q200 qualification. Verify PCB layout accommodates the slightly larger footprint.

Q: What is the primary difference between IHLP1616ABERR22M01 and the original MPIA4040R4-R22-R?

A: The IHLP1616ABERR22M01 maintains identical inductance, tolerance, shielding, and temperature range specifications. The key difference is the reduced continuous current rating (8.5 A versus 10.1 A) and elevated DC resistance (12 mOhm versus 5.3 mOhm). This part is suitable only for applications where the actual operating current remains below 8.5 A. The identical physical footprint (4.45mm x 4.06mm) and lower profile height (1.20mm) may provide layout advantages.

Q: When should SRP1265A-R22M be selected instead of MPIA4020V2-R22-R?

A: SRP1265A-R22M is selected when the application requires significantly higher current capacity (53 A versus 13 A), lower DC resistance (0.6 mOhm versus 6.6 mOhm), or extended temperature range (-40°C to 150°C). The substantially larger physical footprint (13.50mm x 12.50mm) and height (6.40mm) necessitate PCB redesign. This part is appropriate for high-current power delivery applications where space constraints are not limiting factors.

Q: Are all substitute parts RoHS compliant?

A: MPIA4020V2-R22-R is RoHS compliant. IHLP1616ABERR22M01 and SRP1265A-R22M are both ROHS3 compliant. The original MPIA4040R4-R22-R RoHS status is not specified in the provided data.

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

A: MPIA4040R4-R22-R and MPIA4020V2-R22-R use metal composite cores. SRP1265A-R22M uses a carbonyl powder core with drum core, wirewound construction. The carbonyl powder core in SRP1265A-R22M enables significantly lower DC resistance (0.6 mOhm) and higher current capacity (53 A) but results in a larger physical package. Core material selection affects thermal performance, frequency response, and saturation characteristics. Selection depends on application-specific current and thermal requirements.

Q: Can these parts be used interchangeably in high-frequency applications?

A: All substitute parts are tested at 100 kHz inductance frequency, matching the original specification. MPIA4020V2-R22-R has a self-resonant frequency of 165 MHz. IHLP1616ABERR22M01 has a self-resonant frequency of 183 MHz. SRP1265A-R22M has a self-resonant frequency of 130 MHz. Selection for high-frequency applications should consider the self-resonant frequency relative to the operating frequency to avoid impedance anomalies.

Q: What inventory considerations apply to these substitutes?

A: MPIA4020V2-R22-R has 1478 pcs in stock. IHLP1616ABERR22M01 has 17100 pcs in stock, providing the highest availability. SRP1265A-R22M has 808 pcs in stock. All parts are classified as new original stock. IHLP1616ABERR22M01 offers the most robust procurement continuity due to inventory depth.
