PCMC135T-1R5MF Equivalent & Substitute Parts

Part Overview

The PCMC135T-1R5MF is a 1.5 µH unshielded surface mount inductor manufactured by Susumu, rated for 23 A continuous current with a maximum DC resistance of 4.1 mOhm. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and design requirements. Substitute parts must maintain electrical performance across inductance, current rating, saturation current, and DC resistance specifications while accommodating packaging and shielding variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCMC135T-1R5MF is determined by strict equivalence across the following parameters:

Mandatory Electrical Equivalence:

• Inductance: 1.5 µH at 100 kHz test frequency
• Inductance Tolerance: ±20%
• Current Rating: 23 A minimum
• Saturation Current: 48 A minimum
• DC Resistance: 4.1 mOhm maximum

Mandatory Physical Compatibility:

• Mounting Type: Surface Mount
• Package Type: Nonstandard (13.45mm x 12.60mm x 4.80mm maximum height envelope)

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level 1 (Unlimited)

Substitute parts may differ in shielding configuration (shielded versus unshielded), core material composition, and inductor construction type (molded, drum core wirewound) provided all electrical parameters remain within specification. Operating temperature range and packaging format (Tape & Reel versus bulk) do not restrict substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both BMMA001313501R5MX1 (Pulse Electronics) and HCM1305-1R5-R (Eaton - Electronics Division) satisfy the electrical and physical substitution criteria for PCMC135T-1R5MF.

BMMA001313501R5MX1 Selection Criteria:

• Active product status ensures long-term availability and supply chain continuity
• Electrical specifications match PCMC135T-1R5MF exactly (1.5 µH, 23 A, 48 A Isat, 4.1 mOhm DCR)
• Shielded molded construction provides electromagnetic interference mitigation
• Nonstandard package dimensions (13.20mm x 12.90mm x 5.00mm) remain within acceptable PCB layout tolerances
• ROHS3 compliance and MSL 1 rating maintain regulatory and handling requirements
• Tape & Reel packaging supports automated assembly processes

HCM1305-1R5-R Selection Criteria:

• Active product status ensures long-term availability and supply chain continuity
• Electrical specifications exceed PCMC135T-1R5MF requirements (1.5 µH, 23 A, 48 A Isat, 3.16 mOhm DCR—lower resistance improves thermal performance)
• Shielded drum core wirewound construction with iron powder core provides stable inductance characteristics
• Nonstandard package dimensions (13.30mm x 12.20mm x 5.00mm) remain within acceptable PCB layout tolerances
• ROHS3 compliance and MSL 1 rating maintain regulatory and handling requirements
• Tape & Reel packaging supports automated assembly processes
• Operating temperature range (-55°C ~ 125°C) specified for extended environmental applications

Both substitutes are electrically and mechanically compatible. Selection between them depends on electromagnetic shielding requirements, thermal performance priorities, and core material preferences for specific circuit applications.

Frequently Asked Questions (FAQ)

Q: Can BMMA001313501R5MX1 or HCM1305-1R5-R be used as direct replacements for PCMC135T-1R5MF?

A: Both parts satisfy the mandatory electrical and physical substitution criteria. BMMA001313501R5MX1 and HCM1305-1R5-R maintain identical inductance (1.5 µH), current rating (23 A), saturation current (48 A), and surface mount nonstandard package compatibility. Both are ROHS3 compliant with MSL 1 rating. Substitution is electrically and mechanically valid.

Q: What is the difference between shielded and unshielded configurations?

A: PCMC135T-1R5MF is unshielded; both substitutes (BMMA001313501R5MX1 and HCM1305-1R5-R) are shielded. Shielded inductors reduce electromagnetic field radiation and susceptibility to external interference. Shielding may increase component height and footprint slightly but provides improved EMI performance in sensitive circuits.

Q: Does the lower DC resistance of HCM1305-1R5-R (3.16 mOhm vs. 4.1 mOhm) affect compatibility?

A: Lower DC resistance is a performance advantage, not a compatibility issue. HCM1305-1R5-R reduces resistive losses and heat generation compared to PCMC135T-1R5MF. This substitution improves thermal efficiency while maintaining all electrical specifications.

Q: Are the physical dimensions of substitute parts compatible with existing PCB layouts?

A: All three parts use nonstandard packages with similar dimensions. PCMC135T-1R5MF measures 13.45mm x 12.60mm x 4.80mm maximum height. BMMA001313501R5MX1 measures 13.20mm x 12.90mm x 5.00mm. HCM1305-1R5-R measures 13.30mm x 12.20mm x 5.00mm. Dimensional variations are within typical PCB layout tolerances. Verify footprint compatibility with specific board design before implementation.

Q: What is the significance of the ±20% inductance tolerance?

A: All three parts share ±20% inductance tolerance at 100 kHz test frequency. This tolerance band defines acceptable inductance variation across the manufacturing process. Circuit designs must account for this tolerance range in filter, impedance matching, and resonant frequency calculations.

Q: Why are both substitute parts available in Tape & Reel packaging?

A: Tape & Reel (TR) packaging is standard for automated surface mount assembly processes. This format enables high-speed pick-and-place machine compatibility and reduces manual handling. Tape & Reel packaging does not restrict substitution eligibility; it reflects current manufacturing and assembly practices.

Q: Do operating temperature specifications affect substitution suitability?

A: PCMC135T-1R5MF does not specify an operating temperature range. Both substitutes specify -55°C ~ 125°C operation. This specification does not restrict substitution; it indicates the temperature range within which electrical performance is guaranteed. Applications requiring operation outside this range require separate evaluation.

Q: How do core material differences (unspecified vs. iron powder) impact circuit performance?

A: PCMC135T-1R5MF core material is not specified. HCM1305-1R5-R uses iron powder core material. Iron powder cores provide stable inductance across temperature and frequency ranges with lower core losses. Core material differences do not prevent substitution provided inductance, current rating, and DC resistance specifications are met.
