PCMC133E-R68MF Equivalent & Substitute Parts

Part Overview

The PCMC133E-R68MF is a 680 nH unshielded surface mount inductor manufactured by Susumu, rated for 28 A continuous current with a maximum DC resistance of 2.5 mOhm. This component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain electrical performance across inductance, current rating, saturation current, and DC resistance specifications while accommodating packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCMC133E-R68MF are selected based on strict electrical and mechanical compatibility. The following parameters must match or remain within acceptable tolerances:

• Inductance Value: 680 nH at 100 kHz test frequency
• Inductance Tolerance: ±20%
• Current Rating: 28 A minimum continuous current
• Saturation Current (Isat): 49 A minimum
• DC Resistance: 2.5 mOhm maximum
• Mounting Type: Surface Mount
• Package Dimensions: Compatible with nonstandard form factor (13.45mm × 12.60mm × 3.30mm maximum height)
• Compliance: ROHS3 Compliant, MSL 1

Substitutes are grouped into two categories:

Direct Manufacturer Equivalent: PCMB133E-R68MS maintains identical electrical specifications and physical dimensions while offering active product status and tape & reel packaging.

Similar Manufacturer Alternative: BMMA00131335R68MX1 provides equivalent electrical performance with shielded construction, molded type, and extended operating temperature range (-55°C to 125°C), with minor dimensional variations within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

PCMB133E-R68MS is the primary substitute for the obsolete PCMC133E-R68MF. Both components are manufactured by Susumu and maintain identical electrical specifications and physical dimensions. The PCMB133E-R68MS carries active product status, ensuring long-term availability and supply chain continuity. Tape & reel packaging provides compatibility with automated assembly processes. This part is suitable for direct replacement in all applications where the original PCMC133E-R68MF was specified.

BMMA00131335R68MX1 from Pulse Electronics serves as an alternative when shielded construction is required or when extended operating temperature range (-55°C to 125°C) is necessary. The shielded, molded design reduces electromagnetic interference in sensitive circuit environments. Dimensional variations are minimal (13.20mm × 12.90mm footprint, 3.50mm maximum height) and remain compatible with standard nonstandard package mounting patterns. This part maintains all critical electrical parameters and compliance certifications.

Selection between PCMB133E-R68MS and BMMA00131335R68MX1 depends on circuit requirements regarding electromagnetic shielding and thermal operating conditions. Both parts satisfy ROHS3 compliance, MSL 1 moisture sensitivity, and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can PCMB133E-R68MS be used as a direct replacement for PCMC133E-R68MF?

A: Yes. Both parts share identical inductance (680 nH), current rating (28 A), saturation current (49 A), DC resistance (2.5 mOhm maximum), and physical dimensions (13.45mm × 12.60mm × 3.30mm). The PCMB133E-R68MS is manufactured by the same supplier (Susumu) and carries active product status.

Q: What is the primary difference between PCMB133E-R68MS and BMMA00131335R68MX1?

A: The PCMB133E-R68MS is unshielded, while the BMMA00131335R68MX1 is shielded with molded construction. The BMMA part also specifies an operating temperature range of -55°C to 125°C. Electrical performance remains equivalent across both parts.

Q: Are there packaging differences between the main part and substitutes?

A: The original PCMC133E-R68MF packaging is not specified. Both PCMB133E-R68MS and BMMA00131335R68MX1 are supplied in tape & reel (TR) format, which is standard for automated assembly processes.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both PCMB133E-R68MS and BMMA00131335R68MX1 are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity), and are REACH unaffected, matching the original part's compliance profile.

Q: What are the dimensional tolerances for the substitute parts?

A: PCMB133E-R68MS maintains identical dimensions to the original (13.45mm × 12.60mm × 3.30mm maximum height). BMMA00131335R68MX1 has minor variations (13.20mm × 12.90mm × 3.50mm maximum height) that remain compatible with standard nonstandard package mounting patterns.

Q: Should shielding be considered when selecting a substitute?

A: Shielding selection depends on circuit design requirements. The PCMB133E-R68MS maintains the unshielded design of the original part. The BMMA00131335R68MX1 provides shielded construction for applications requiring electromagnetic interference mitigation.

Q: Are both substitute parts actively manufactured?

A: Yes. Both PCMB133E-R68MS and BMMA00131335R68MX1 carry active product status, ensuring ongoing availability and supply chain support.
