MPC1055LR36C Equivalent & Substitute Parts

Part Overview

The MPC1055LR36C is a 360 nH shielded inductor manufactured by KEMET, rated for 32 A continuous current with 0.75 mOhm DC resistance. This component is designed for surface mount applications in the 2-SMD, J-Lead package configuration. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain the same inductance value, shielding characteristics, and current handling capability while meeting modern component availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC1055LR36C is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 360 nH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Shielding: Shielded construction required
• Mounting type: Surface mount only
• Package configuration: 2-SMD, J-Lead format

Current Handling Parameters:

• Continuous current rating: minimum 30 A (MPC1055LR36C rated 32 A)
• Saturation current (Isat): minimum 30 A

Electrical Performance Parameters:

• DC resistance (DCR): maximum 1.15 mOhm (MPC1055LR36C is 0.75 mOhm)
• Test frequency: 100 kHz

Compliance & Environmental Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited) preferred
• Operating temperature range: must encompass or exceed -20°C to 120°C

Two substitute parts meet these criteria: ETQ-P4LR36AFC (Panasonic) and IHLP4040DZERR36M11 (Vishay Dale). Both maintain the 360 nH inductance specification, shielded construction, surface mount configuration, and regulatory compliance. Variations in core material, DCR, and physical dimensions are within acceptable substitution parameters for this product category.

Parameter Comparison

Engineering Selection Recommendations

ETQ-P4LR36AFC (Panasonic Electronic Components): This substitute is active in production with ROHS3 compliance and MSL 1 rating. The part maintains 360 nH inductance at ±20% tolerance and 2-SMD, J-Lead package configuration. DC resistance of 0.76 mOhm is functionally equivalent to the original 0.75 mOhm specification. Current rating of 30 A is within acceptable range for applications rated at 32 A. Physical dimensions are nearly identical (11.50mm x 10.00mm vs. 11.70mm x 10.00mm), with reduced height (4.00mm vs. 5.50mm). Metal composite core construction provides alternative performance characteristics while maintaining shielding requirements. This substitute is suitable for direct replacement in applications where the reduced height profile is compatible with PCB layout constraints.

IHLP4040DZERR36M11 (Vishay Dale): This substitute is active in production with ROHS3 compliance and MSL 1 rating. The part maintains 360 nH inductance at ±20% tolerance and shielded construction. Current rating of 32 A matches the original specification exactly. DC resistance of 1.15 mOhm maximum is higher than the original 0.75 mOhm but remains within acceptable electrical performance parameters for this inductance category. Operating temperature range of -55°C to 125°C exceeds the original -20°C to 120°C specification. Physical dimensions are compact (10.80mm x 10.16mm) with 4.00mm height. Package designation is listed as nonstandard, requiring verification of PCB footprint compatibility with 2-SMD, J-Lead layout requirements. This substitute is suitable for applications requiring extended temperature performance and compact form factor.

Frequently Asked Questions (FAQ)

Q: Can ETQ-P4LR36AFC be used as a direct replacement for MPC1055LR36C?

A: ETQ-P4LR36AFC meets the critical electrical specifications: 360 nH inductance, ±20% tolerance, 30 A current rating, 0.76 mOhm DCR, shielded construction, and 2-SMD J-Lead package. The 30 A rating is acceptable for 32 A applications. Physical dimensions are compatible with standard PCB layouts. ROHS3 compliance and MSL 1 rating match the original. This part is suitable for direct replacement in most applications.

Q: What is the difference in DC resistance between the substitutes?

A: MPC1055LR36C has 0.75 mOhm DCR. ETQ-P4LR36AFC has 0.76 mOhm DCR (0.01 mOhm difference, negligible). IHLP4040DZERR36M11 has 1.15 mOhm maximum DCR (0.40 mOhm higher). The higher DCR in the Vishay part results in increased power dissipation; applications sensitive to thermal performance should account for this difference.

Q: Are there package compatibility concerns with IHLP4040DZERR36M11?

A: IHLP4040DZERR36M11 is designated as nonstandard package, while MPC1055LR36C uses standard 2-SMD, J-Lead configuration. Physical dimensions differ (10.80mm x 10.16mm vs. 11.70mm x 10.00mm). PCB footprint compatibility must be verified before substitution. The reduced height (4.00mm vs. 5.50mm) may provide layout advantages but requires confirmation of solder pad alignment.

Q: Which substitute has the better temperature performance?

A: IHLP4040DZERR36M11 operates from -55°C to 125°C, exceeding the original -20°C to 120°C range. ETQ-P4LR36AFC operating temperature range is not specified in available data. For applications requiring extended temperature operation, IHLP4040DZERR36M11 provides documented performance across a wider range.

Q: Do all substitutes maintain shielding characteristics?

A: Yes. MPC1055LR36C (ferrite core), ETQ-P4LR36AFC (metal composite core), and IHLP4040DZERR36M11 (core material not specified) are all specified as shielded inductors. Shielding construction is maintained across all substitutes, meeting EMI suppression requirements.

Q: What is the current saturation difference between parts?

A: MPC1055LR36C has Isat of 35 A. ETQ-P4LR36AFC Isat is not specified. IHLP4040DZERR36M11 has Isat of 30 A. For applications operating near saturation limits, the Vishay part (30 A Isat) provides less margin than the original (35 A Isat). ETQ-P4LR36AFC requires manufacturer consultation for saturation specifications.

Q: Are all parts RoHS3 compliant?

A: Yes. MPC1055LR36C, ETQ-P4LR36AFC, and IHLP4040DZERR36M11 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current regulatory requirements for electronic component procurement.
