PCMC133E-R56MF Equivalent & Substitute Parts

Part Overview

The PCMC133E-R56MF is a 560 nH fixed unshielded inductor manufactured by Susumu, rated for 29 A continuous current with a maximum DC resistance of 2.2 mOhm. This surface mount component is designed for high-current applications requiring low inductance values and minimal resistance characteristics. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCMC133E-R56MF is determined by strict equivalence in the following electrical parameters: inductance value (560 nH), inductance tolerance (±20%), current rating (minimum 29 A), saturation current (minimum 51 A), and DC resistance (maximum 2.2 mOhm). Mechanical compatibility requires surface mount packaging with nonstandard case dimensions and moisture sensitivity level MSL 1. Regulatory compliance includes ROHS3 certification and REACH unaffected status. Substitute parts must satisfy all these criteria simultaneously. Variations in shielding type, construction method (molded versus wirewound), and operating temperature range do not disqualify substitution when electrical and mechanical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

BMMA00131335R56MX1 (Pulse Electronics) is the primary substitute for the PCMC133E-R56MF. This part maintains identical electrical specifications: 560 nH inductance, ±20% tolerance, 29 A current rating, 51 A saturation current, and 2.2 mOhm maximum DC resistance. The component is active in production with full ROHS3 compliance and MSL 1 rating. The molded construction and shielded design provide electromagnetic containment benefits in high-density layouts. Operating temperature range extends to -55°C ~ 125°C. Packaging is supplied in Tape & Reel format with 1132 units in current inventory.

SCIHP1338-R56M (Signal Transformer) serves as a secondary substitute with the following considerations: the current rating is reduced to 24 A (below the 29 A requirement of the original part) and saturation current is 47 A (below the 51 A specification). DC resistance is marginally higher at 2.3 mOhm maximum. The inductance test frequency is 200 kHz rather than 100 kHz. This part is suitable only for applications where the 24 A current rating is sufficient and where the reduced saturation margin is acceptable. The wirewound shielded construction and active product status provide long-term availability. Operating temperature range is -55°C ~ 125°C with ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can BMMA00131335R56MX1 directly replace PCMC133E-R56MF in all applications?

A: Yes. The BMMA00131335R56MX1 maintains all critical electrical parameters: 560 nH inductance, 29 A current rating, 51 A saturation current, and 2.2 mOhm maximum DC resistance. The shielded design and molded construction are compatible with surface mount assembly processes. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What are the limitations of SCIHP1338-R56M as a substitute?

A: The SCIHP1338-R56M has a reduced current rating of 24 A compared to the 29 A specification of the original part. Saturation current is 47 A versus 51 A. DC resistance is 2.3 mOhm maximum instead of 2.2 mOhm. These differences restrict its use to applications where the lower current and saturation ratings are acceptable.

Q: How do shielding differences affect substitution?

A: The original PCMC133E-R56MF is unshielded, while both substitute parts are shielded. Shielded inductors reduce electromagnetic interference emission and susceptibility. In applications where electromagnetic containment is required, the shielded substitutes provide additional benefits. In applications where shielding is not required, the shielded design does not create incompatibility.

Q: Are there packaging or dimensional concerns with these substitutes?

A: All three parts use nonstandard surface mount packages with similar footprints. The PCMC133E-R56MF measures 0.530" L x 0.496" W x 0.130" H. The BMMA00131335R56MX1 measures 0.520" L x 0.508" W x 0.138" H. The SCIHP1338-R56M measures 0.543" L x 0.508" W x 0.150" H. Dimensional variations are minor and typically accommodated by standard PCB layout tolerances.

Q: What is the inventory status of these substitutes?

A: BMMA00131335R56MX1 has 1132 units in current stock with active product status. SCIHP1338-R56M has 995 units in current stock with active product status. Both parts are available for immediate procurement.

Q: Do all parts meet the same regulatory and compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All parts have MSL 1 (unlimited) moisture sensitivity rating. The PCMC133E-R56MF is obsolete, while BMMA00131335R56MX1 and SCIHP1338-R56M are active products with ongoing manufacturer support.
