Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCMC104T-2R2MN are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Current rating: 12 A minimum
• DC resistance: 7 mOhm maximum
• Inductance test frequency: 100 kHz

Mechanical Parameters:

• Mounting type: Surface mount
• Package classification: Nonstandard
• Physical dimensions within acceptable tolerance ranges

Compliance Parameters:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)

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

Parameter Comparison

Engineering Selection Recommendations

PCMB104T-2R2MS (Direct Equivalent - Susumu)

The PCMB104T-2R2MS is the primary direct equivalent from the same manufacturer. It maintains identical electrical specifications (2.2 µH, 12 A, 7 mOhm DCR) and is currently in active production status. Physical dimensions are comparable with minor variations (11.00mm x 10.00mm versus 11.50mm x 10.00mm). This part is available in Tape & Reel packaging format and carries full RoHS3 compliance. The saturation current rating is 18 A compared to 27 A in the main part, which remains within acceptable operating margins for 12 A continuous current applications.

BMCA001010402R2MA1 and BMMA001010402R2MX1 (Similar Alternatives - Pulse Electronics)

Both Pulse Electronics parts (BMCA001010402R2MA1 and BMMA001010402R2MX1) provide functional equivalence with identical core electrical parameters. These are shielded molded inductors, contrasting with the unshielded design of the main part. Both maintain 2.2 µH inductance, 12 A current rating, and 7 mOhm maximum DCR. Both are active products with RoHS3 compliance and specified operating temperature ranges (-55°C to 125°C). The BMMA001010402R2MX1 offers dimensional alignment closest to the original part (11.50mm x 10.00mm x 4.00mm). Both alternatives feature saturation current ratings of 27 A, matching the main part specification.

Selection Criteria:

For direct replacement requiring minimal design modification, PCMB104T-2R2MS is recommended due to manufacturer continuity and identical unshielded topology. For applications where shielding provides electromagnetic interference benefits, BMMA001010402R2MX1 is recommended due to dimensional compatibility and active product status. All three substitute parts satisfy the core electrical requirements and compliance certifications of the obsolete PCMC104T-2R2MN.

Frequently Asked Questions (FAQ)

Q: Can PCMB104T-2R2MS be used as a direct replacement for PCMC104T-2R2MN?

A: Yes. Both parts share identical inductance (2.2 µH), current rating (12 A), DC resistance (7 mOhm max), and inductance tolerance (±20%). Physical dimensions are comparable (11.00mm x 10.00mm versus 11.50mm x 10.00mm). The primary difference is packaging format (Tape & Reel versus bulk) and saturation current (18 A versus 27 A). For 12 A continuous current applications, the saturation margin remains acceptable.

Q: What is the difference between unshielded and shielded inductors in the substitute options?

A: The main part (PCMC104T-2R2MN) and direct equivalent (PCMB104T-2R2MS) are unshielded inductors. The Pulse Electronics alternatives (BMCA001010402R2MA1 and BMMA001010402R2MX1) are shielded molded inductors. Shielding reduces electromagnetic field radiation and susceptibility to external interference. Electrical performance parameters (inductance, current rating, DCR) remain equivalent across both types.

Q: Are there dimensional constraints when substituting these parts?

A: Physical dimensions vary slightly across substitutes. The main part measures 11.50mm x 10.00mm x 4.00mm. PCMB104T-2R2MS measures 11.00mm x 10.00mm x 3.80mm. BMCA001010402R2MA1 measures 11.60mm x 10.20mm x 4.00mm. BMMA001010402R2MX1 measures 11.50mm x 10.00mm x 4.00mm. PCB layout and thermal management considerations may require evaluation for specific applications.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts (PCMB104T-2R2MS, BMCA001010402R2MA1, BMMA001010402R2MX1) are RoHS3 compliant with MSL rating 1 (Unlimited). REACH status is unaffected for all parts. ECCN classification is EAR99 for all options.

Q: What is the significance of saturation current differences?

A: The main part and Pulse Electronics alternatives specify 27 A saturation current. The direct equivalent PCMB104T-2R2MS specifies 18 A. For applications operating at or below 12 A continuous current, both saturation ratings provide adequate margin. Applications requiring operation closer to saturation limits should reference detailed inductor curves from manufacturers.

Q: Which substitute part is recommended for new designs?

A: For new designs, BMMA001010402R2MX1 is recommended due to active product status, specified operating temperature range (-55°C to 125°C), dimensional compatibility with the original part, and shielded topology benefits. PCMB104T-2R2MS remains a valid alternative for designs requiring unshielded topology and manufacturer continuity with Susumu.

Q: Are packaging format differences significant?

A: The main part is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format. This affects procurement, handling, and automated assembly processes. Tape & Reel format is standard for high-volume manufacturing and provides improved component protection during storage and transport.
