PCMC053T-1R2MN Equivalent & Substitute Parts

Part Overview

The PCMC053T-1R2MN is a 1.2 µH unshielded surface mount inductor manufactured by Susumu, rated for 6.5 A continuous current with a maximum DC resistance of 16 mOhm. This component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and repair applications. Substitute parts must maintain electrical performance across inductance, current rating, and DC resistance specifications while accommodating modern packaging and availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCMC053T-1R2MN are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Inductance: 1.2 µH
• Inductance Tolerance: ±20%
• Current Rating: 6.5 A
• DC Resistance: 16 mOhm maximum
• Inductance Test Frequency: 100 kHz

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Saturation Current: 10.5 A minimum

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts meet these criteria: PCMB053T-1R2MS (Susumu, active status) and BMMA000505301R2MX1 (Pulse Electronics, active status). Both maintain identical electrical specifications while differing in packaging configuration and shielding characteristics.

Parameter Comparison

Engineering Selection Recommendations

PCMB053T-1R2MS (Susumu) is the primary substitute for PCMC053T-1R2MN. Both components are manufactured by Susumu and maintain identical electrical specifications. PCMB053T-1R2MS carries active product status with 1266 units in stock, ensuring supply continuity. The component is packaged in Tape & Reel format (1919/4848 Metric) and features a slightly reduced seated height (2.80mm vs. 3.00mm) and marginally smaller length (4.85mm vs. 5.20mm). These dimensional differences are within typical PCB layout tolerances for surface mount applications. ROHS3 compliance and MSL 1 rating are maintained.

BMMA000505301R2MX1 (Pulse Electronics) serves as a secondary substitute when Susumu components are unavailable. This component maintains all critical electrical parameters and carries active product status with 1114 units in stock. The primary distinction is shielding: BMMA000505301R2MX1 is shielded, whereas PCMC053T-1R2MN is unshielded. Shielding reduces electromagnetic interference but may affect circuit performance in applications sensitive to inductance characteristics. The saturation current is marginally lower (10.5A vs. 11A), remaining within acceptable operating margins for 6.5A rated applications. Operating temperature range (-55°C ~ 125°C) is specified for this component. Dimensional differences are minimal (5.30mm length vs. 5.20mm, identical 3.00mm height).

Both substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can PCMB053T-1R2MS directly replace PCMC053T-1R2MN in existing designs?

A: Yes. PCMB053T-1R2MS maintains identical electrical specifications (1.2 µH inductance, 6.5 A current rating, 16 mOhm DC resistance) and mounting type (surface mount). Dimensional variations are minimal and within standard PCB layout tolerances. The primary difference is packaging format (Tape & Reel vs. bulk) and slightly reduced height (2.80mm vs. 3.00mm), which does not affect electrical performance.

Q: What is the key difference between PCMB053T-1R2MS and BMMA000505301R2MX1?

A: Both components meet the electrical requirements of PCMC053T-1R2MN. The primary difference is shielding: PCMB053T-1R2MS is unshielded (matching the original), while BMMA000505301R2MX1 is shielded. Shielding reduces electromagnetic interference but may alter inductance characteristics in sensitive applications. BMMA000505301R2MX1 also specifies an operating temperature range (-55°C ~ 125°C), whereas PCMB053T-1R2MS does not provide this specification.

Q: Are there any compliance concerns when substituting these parts?

A: No. All three components (original and both substitutes) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. REACH status is unaffected for all components. Regulatory and environmental compliance is maintained across all substitution options.

Q: Does the saturation current difference between PCMB053T-1R2MS (11A) and BMMA000505301R2MX1 (10.5A) affect circuit performance?

A: No, for applications operating at the 6.5 A rated current. Both components provide sufficient saturation margin above the rated current. The 0.5 A difference becomes relevant only in transient or fault conditions exceeding normal operating parameters.

Q: What packaging considerations apply to these substitutes?

A: PCMC053T-1R2MN packaging format is not specified in available data. PCMB053T-1R2MS is supplied in Tape & Reel (TR) format, standard for automated assembly. BMMA000505301R2MX1 is also supplied in Tape & Reel format. Both formats are compatible with standard pick-and-place equipment used in surface mount assembly processes.

Q: Can BMMA000505301R2MX1 be used in applications requiring unshielded inductors?

A: BMMA000505301R2MX1 is shielded, which differs from the unshielded PCMC053T-1R2MN. In applications where shielding characteristics are critical to circuit performance, PCMB053T-1R2MS (unshielded) is the appropriate substitute. Shielding affects electromagnetic field distribution and may impact circuit behavior in sensitive RF or high-frequency applications.
