PM54-150M Equivalent & Substitute Parts

Part Overview

The PM54-150M is a 15 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.3 A with 140 mOhm DC resistance. This component is classified as obsolete, with limited new original inventory of 764 pieces available. Due to its obsolete status and the availability of active product alternatives with improved specifications and compliance certifications, equivalent substitute parts are necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitute parts for the PM54-150M are classified based on strict electrical and mechanical parameter alignment:

Direct Manufacturer Substitutes maintain identical electrical specifications (15 µH inductance, 1.3 A current rating, 140 mOhm DCR) and physical footprint (5.80mm x 5.80mm x 4.80mm). These parts are sourced from the same manufacturer (Bourns Inc.) and represent active product alternatives with enhanced compliance and performance characteristics.

Similar Cross-Manufacturer Substitutes provide equivalent electrical performance (15 µH inductance, 1.3 A current rating, 140 mOhm DCR) from alternative manufacturers (Sumida America Components Inc., API Delevan Inc.). Physical dimensions may vary within acceptable tolerances, and electrical parameters remain within the functional requirements of the original design.

Substitution Criteria:

Inductance value: 15 µH (fixed requirement)
Current rating: ≥1.3 A minimum
DC resistance: ≤140 mOhm maximum
Core material: Ferrite
Shielding: Unshielded
Mounting: Surface Mount
Physical footprint: Compatible with 5.80mm x 5.80mm pad layout

Engineering Selection Recommendations

Primary Recommendation: PM54-150M-RC

The PM54-150M-RC is the direct successor from Bourns Inc., offering identical electrical specifications with enhanced compliance. This part is RoHS3 compliant, active in production with 3454 pieces in stock, and features an extended operating temperature range (-40°C to 125°C) compared to the obsolete PM54-150M. The tape and reel packaging supports automated assembly processes.

Secondary Recommendation: SDR0604-150YL

The SDR0604-150YL from Bourns Inc. provides tighter inductance tolerance (±15% versus ±20%) and is available in cut tape and Digi-Reel packaging options. This part is RoHS3 compliant and active, with 4000 pieces in inventory. The improved tolerance specification may benefit designs requiring tighter inductance control.

Cross-Manufacturer Alternatives: CR54NP-150MC, CD54NP-150MC

Both Sumida America Components Inc. parts maintain the core electrical specifications and are RoHS3 compliant with active product status. CR54NP-150MC and CD54NP-150MC differ primarily in physical dimensions (5.80mm x 5.30mm and 5.80mm x 5.20mm respectively versus the original 5.80mm x 5.80mm). These parts are suitable for designs where minor footprint variations are acceptable.

Extended Temperature Range Option: PD54R-153K

The API Delevan Inc. PD54R-153K offers the widest operating temperature range (-55°C to 125°C) and tightest inductance tolerance (±10%). Current rating is 1.27 A (slightly below the 1.3 A specification) and DCR is 160 mOhm maximum. This part is appropriate for applications requiring extended temperature performance and tighter inductance control, provided the reduced current margin is acceptable.

Frequently Asked Questions (FAQ)

Q: Can PM54-150M-RC be used as a direct replacement for PM54-150M?

A: Yes. PM54-150M-RC maintains identical inductance (15 µH), current rating (1.3 A), and DC resistance (140 mOhm) specifications. The primary differences are improved compliance (RoHS3), extended temperature range (-40°C to 125°C), and active product status. Physical footprint and mounting type are identical.

Q: What is the difference between PM54-150M-RC and SDR0604-150YL?

A: Both are Bourns Inc. products with identical inductance and current ratings. SDR0604-150YL offers tighter inductance tolerance (±15% versus ±20%) and is available in cut tape and Digi-Reel packaging. PM54-150M-RC is supplied in tape and reel format. Selection depends on packaging requirements and tolerance specifications for your application.

Q: Are cross-manufacturer parts (Sumida, API Delevan) fully compatible?

A: Cross-manufacturer parts meet the core electrical requirements (15 µH inductance, 1.3 A current rating, 140 mOhm DCR) and are RoHS3 compliant. Physical dimensions vary slightly. Verify that footprint variations and any differences in saturation current or temperature range are acceptable for your specific circuit design before implementation.

Q: Why does PD54R-153K have a lower current rating (1.27 A) than the original?

A: The PD54R-153K is rated for 1.27 A continuous current, which is 2.3% below the PM54-150M specification of 1.3 A. This part is suitable only for applications where the design current does not exceed 1.27 A. Verify circuit requirements before selection.

Q: What packaging options are available for these substitutes?

A: PM54-150M-RC is supplied in tape and reel (TR). SDR0604-150YL is available in cut tape (CT) and Digi-Reel. Sumida parts (CR54NP-150MC, CD54NP-150MC) are supplied in tape and reel. API Delevan PD54R-153K is supplied in tape and reel. Select based on your assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (PM54-150M-RC, SDR0604-150YL, CR54NP-150MC, CD54NP-150MC, PD54R-153K) are RoHS3 compliant. The original PM54-150M is RoHS non-compliant, making the transition to compliant alternatives necessary for regulatory adherence.
