Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCMC133E-2R2MF is determined by the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 2.2 µH with ±20% tolerance
• Current rating: minimum 16 A continuous
• DC resistance: maximum 8 mOhm
• Saturation current: minimum 29 A
• Mounting type: Surface Mount
• Inductance test frequency: 100 kHz
• Compliance: RoHS3 and REACH requirements

Secondary Considerations:

• Physical dimensions and height constraints
• Shielding characteristics (unshielded vs. shielded)
• Core material and construction type
• Operating temperature range
• Packaging format (bulk vs. tape and reel)

The substitute parts identified maintain the core electrical specifications while offering variations in construction type, shielding, and physical form factor. These variations are acceptable within the functional requirements of the 2.2 µH inductor category.

Parameter Comparison

Engineering Selection Recommendations

PCMB133E-2R2MS (Direct Equivalent)

The PCMB133E-2R2MS is the primary substitute for the obsolete PCMC133E-2R2MF. Both parts are manufactured by Susumu and share identical electrical specifications: 2.2 µH inductance, 16 A current rating, 8 mOhm maximum DC resistance, and 29 A saturation current. The PCMB133E-2R2MS maintains the same physical dimensions and unshielded construction. The primary difference is product status: PCMB133E-2R2MS is active and available in tape and reel packaging, providing superior procurement continuity. Both parts are RoHS3 compliant with unlimited moisture sensitivity rating.

BMMA001313352R2MX1 (Alternative Substitute)

The BMMA001313352R2MX1 manufactured by Pulse Electronics is a shielded molded inductor that meets the core electrical requirements: 2.2 µH inductance, 16 A current rating, 8 mOhm maximum DC resistance, and 29 A saturation current. This part introduces shielding, which may be beneficial in noise-sensitive applications but represents a design variation from the unshielded original. Physical dimensions are comparable (13.20mm x 12.90mm x 3.50mm). The part is active and RoHS3 compliant. Selection of this substitute requires confirmation that shielded construction is compatible with the application circuit.

HCM1305-2R2-R (Alternative Substitute)

The HCM1305-2R2-R manufactured by Eaton - Electronics Division is a shielded drum core wirewound inductor with iron powder core material. This part exceeds the minimum electrical specifications with 20 A current rating (vs. 16 A required), 32 A saturation current (vs. 29 A required), and lower DC resistance of 5.29 mOhm maximum (vs. 8 mOhm maximum). The inductor maintains 2.2 µH inductance with ±20% tolerance. Physical dimensions are comparable in length and width (13.30mm x 12.20mm) but height is increased to 5.00mm. This part is active and RoHS3 compliant. Selection of this substitute requires verification that the increased height does not violate PCB layout constraints and that shielded construction is acceptable.

All three substitute parts maintain RoHS3 compliance, unlimited moisture sensitivity rating, and 100 kHz inductance test frequency. Selection among these options depends on application-specific requirements regarding shielding, physical form factor, and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can PCMB133E-2R2MS directly replace PCMC133E-2R2MF without circuit modification?

A: Yes. The PCMB133E-2R2MS is a direct electrical and mechanical equivalent. Both parts share identical inductance (2.2 µH), current rating (16 A), DC resistance (8 mOhm maximum), saturation current (29 A), and physical dimensions (13.45mm x 12.60mm x 3.30mm). The primary difference is packaging format: PCMC133E-2R2MF is supplied in bulk, while PCMB133E-2R2MS is supplied in tape and reel format. No circuit modifications are required.

Q: What is the difference between shielded and unshielded inductors in these substitutes?

A: The PCMC133E-2R2MF and PCMB133E-2R2MS are unshielded inductors, meaning the magnetic field radiates outward from the component. The BMMA001313352R2MX1 and HCM1305-2R2-R are shielded inductors, which contain the magnetic field within the component structure. Shielded construction reduces electromagnetic interference (EMI) with adjacent circuit elements but typically increases component height and cost. Selection between shielded and unshielded depends on circuit layout and EMI requirements.

Q: Are there current rating differences among the substitute parts?

A: Yes. The PCMC133E-2R2MF, PCMB133E-2R2MS, and BMMA001313352R2MX1 are all rated for 16 A continuous current. The HCM1305-2R2-R is rated for 20 A continuous current, providing 25% additional current capacity. For applications operating at or near 16 A, the HCM1305-2R2-R provides additional thermal margin. However, the higher current rating does not affect substitution compatibility for 16 A applications.

Q: What is the impact of DC resistance differences on circuit performance?

A: The PCMC133E-2R2MF, PCMB133E-2R2MS, and BMMA001313352R2MX1 all specify 8 mOhm maximum DC resistance. The HCM1305-2R2-R specifies 5.29 mOhm maximum DC resistance, representing approximately 34% lower resistance. Lower DC resistance reduces resistive losses and heat generation during operation. For power supply and filtering applications, the HCM1305-2R2-R may provide improved efficiency. However, the difference is not significant for most general-purpose inductor applications.

Q: Can the HCM1305-2R2-R be used if PCB space is limited?

A: The HCM1305-2R2-R has increased height (5.00mm) compared to the original PCMC133E-2R2MF (3.30mm) and other substitutes. This 1.70mm height increase may violate PCB layout constraints in space-limited designs. Verify available vertical clearance before selecting this substitute. The PCMB133E-2R2MS and BMMA001313352R2MX1 maintain comparable heights to the original part and are preferred for height-constrained applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The PCMB133E-2R2MS, BMMA001313352R2MX1, and HCM1305-2R2-R are all RoHS3 compliant. All parts maintain unlimited moisture sensitivity rating (MSL 1). These compliance characteristics match the original PCMC133E-2R2MF, ensuring compatibility with RoHS3 regulated supply chains and applications.

Q: What is the difference between tape and reel packaging and bulk packaging?

A: The PCMC133E-2R2MF is supplied in bulk packaging, suitable for manual assembly or small-quantity procurement. The PCMB133E-2R2MS, BMMA001313352R2MX1, and HCM1305-2R2-R are supplied in tape and reel (TR) format, which is standard for automated pick-and-place assembly equipment. Tape and reel packaging improves manufacturing efficiency for production volumes. For prototype or low-volume applications, bulk packaging may be preferred. For production assembly, tape and reel format is standard.

Q: Which substitute part is recommended for new designs?

A: The PCMB133E-2R2MS is recommended as the primary substitute for new designs. It is a direct electrical and mechanical equivalent to the obsolete PCMC133E-2R2MF, manufactured by the same supplier (Susumu), with active product status and standard tape and reel packaging. This selection ensures design continuity and procurement reliability. The BMMA001313352R2MX1 and HCM1305-2R2-R are acceptable alternatives if shielding or enhanced current capacity is required by the application.
