Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCMC104T-R68MN are identified based on strict electrical and mechanical parameter matching. The critical parameters determining substitution eligibility are:

Electrical Parameters:

• Inductance value: 680 nH
• Inductance tolerance: ±20%
• Current rating: 22 A minimum
• Saturation current: 39 A
• DC resistance: 2.7 mOhm maximum
• Test frequency: 100 kHz

Mechanical Parameters:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Environmental compliance: RoHS3 Compliant, REACH Unaffected

Substitute parts are grouped into two categories: direct manufacturer alternatives (same manufacturer, different series) and similar manufacturer alternatives (different manufacturer, equivalent electrical specifications).

Parameter Comparison

Engineering Selection Recommendations

PCMB104T-R68MS (Direct Susumu Alternative)

The PCMB104T-R68MS is the primary substitute for the obsolete PCMC104T-R68MN. Both parts are manufactured by Susumu and share identical electrical specifications: 680 nH inductance, ±20% tolerance, 22 A current rating, 39 A saturation current, and 2.7 mOhm maximum DC resistance. The PCMB104T-R68MS is currently in active production status with 717 units in stock. Mechanical dimensions are comparable, with the PCMB variant measuring 11.00mm x 10.00mm (versus 11.50mm x 10.00mm for the main part) and a seated height of 3.80mm (versus 4.00mm). Both parts maintain unshielded construction and identical environmental compliance certifications. The primary distinction is packaging format: the PCMB104T-R68MS is supplied in Tape & Reel format, whereas the main part is supplied in bulk.

BMMA00101040R68MX1 (Pulse Electronics Alternative)

The BMMA00101040R68MX1 manufactured by Pulse Electronics provides an alternative from a different manufacturer. This part matches all critical electrical parameters: 680 nH inductance, ±20% tolerance, 22 A current rating, 39 A saturation current, and 2.7 mOhm maximum DC resistance. The BMMA variant is actively produced with 798 units in stock. Physical dimensions are identical to the main part (11.50mm x 10.00mm, 4.00mm seated height). A significant distinction is the shielded construction of the BMMA variant, compared to the unshielded design of the PCMC104T-R68MN. The BMMA00101040R68MX1 specifies an operating temperature range of −55°C to 125°C and is supplied in Tape & Reel packaging. All environmental compliance certifications match the main part.

Selection Criteria

For direct replacement in existing designs without modification, the PCMB104T-R68MS is the optimal choice due to identical shielding characteristics and Susumu manufacturer continuity. The BMMA00101040R68MX1 is suitable for applications where shielded construction provides electromagnetic interference mitigation benefits or where the specified operating temperature range is required. Both alternatives are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the PCMB104T-R68MS be used as a direct replacement for the PCMC104T-R68MN?

A: Yes. Both parts share identical electrical specifications (680 nH, ±20%, 22 A, 2.7 mOhm DCR) and unshielded construction. The PCMB104T-R68MS is the active production equivalent. Mechanical dimensions are comparable with minor variations in length (11.00mm versus 11.50mm) and height (3.80mm versus 4.00mm). Verify PCB layout accommodates the slightly smaller footprint.

Q: What is the primary difference between the PCMB104T-R68MS and BMMA00101040R68MX1?

A: The PCMB104T-R68MS maintains unshielded construction identical to the main part, while the BMMA00101040R68MX1 features shielded construction. Both meet identical electrical specifications. The BMMA variant includes a specified operating temperature range (−55°C to 125°C), whereas the main part does not specify operating temperature limits.

Q: Are there packaging format differences between these substitutes?

A: Yes. The PCMC104T-R68MN is supplied in bulk packaging. Both substitute parts (PCMB104T-R68MS and BMMA00101040R68MX1) are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Do all three parts meet the same environmental compliance standards?

A: Yes. The PCMC104T-R68MN, PCMB104T-R68MS, and BMMA00101040R68MX1 are all RoHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). All three parts carry EAR99 ECCN classification.

Q: Which substitute should be selected for new designs?

A: The PCMB104T-R68MS is recommended for new designs requiring unshielded construction and Susumu manufacturer continuity. The BMMA00101040R68MX1 is suitable for applications requiring shielded construction or the specified operating temperature range. Both are in active production with adequate inventory availability.

Q: Are the saturation current ratings identical across all three parts?

A: Yes. All three parts (PCMC104T-R68MN, PCMB104T-R68MS, and BMMA00101040R68MX1) specify a saturation current (Isat) of 39 A, providing identical current handling capability under saturation conditions.
