PM104SH-150-RC Equivalent & Substitute Parts

Part Overview

The PM104SH-150-RC is a 15 µH shielded drum core wirewound inductor manufactured by Bourns Inc., rated for 2.8 A continuous current with a maximum DC resistance of 37 mOhm. This surface mount component is designed for applications requiring controlled inductance with ferrite core shielding in a compact 10.00mm × 10.00mm footprint. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductor category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM104SH-150-RC are qualified based on the following critical parameters:

• Inductance Value: 15 µH (within ±30% tolerance specification)
• Current Rating: Minimum 2.8 A continuous current capability
• DC Resistance: Maximum 37 mOhm (electrical performance constraint)
• Core Type: Ferrite drum core, wirewound construction
• Shielding: Shielded configuration required
• Mounting: Surface mount, nonstandard package
• Temperature Range: -40°C to 125°C operating window
• Compliance: ROHS3 compliant, MSL 1 rating

Two substitute parts meet these criteria with documented electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

SRU1038-150Y (Bourns Inc.) provides direct electrical and mechanical equivalence to the PM104SH-150-RC. Both parts share identical inductance, current rating, DC resistance specification, and physical footprint (10.00mm × 10.00mm × 4.10mm). Both maintain Active product status with ROHS3 compliance and unlimited MSL rating. This substitute is suitable for direct replacement in applications where the PM104SH-150-RC is specified.

DR1040-150-R (Eaton - Electronics Division) qualifies as a substitute with the following considerations: The part maintains the 15 µH inductance and ±30% tolerance specification. The current rating of 3.1 A exceeds the PM104SH-150-RC requirement of 2.8 A, providing additional current capacity. The DC resistance specification of 50 mOhm Max is higher than the 37 mOhm Max of the primary part, representing a 35% increase in resistance. Physical dimensions differ slightly (10.50mm × 10.30mm versus 10.00mm × 10.00mm), with a lower seated height of 4.00mm. The part maintains Active status, ROHS3 compliance, and unlimited MSL rating. Selection of this substitute requires confirmation that the increased DC resistance and dimensional variance are acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can SRU1038-150Y be used as a direct replacement for PM104SH-150-RC?

A: Yes. Both parts are manufactured by Bourns Inc. with identical inductance (15 µH), current rating (2.8 A), DC resistance (37 mOhm), and physical dimensions (10.00mm × 10.00mm × 4.10mm). Electrical and mechanical compatibility is confirmed.

Q: What is the key difference between PM104SH-150-RC and DR1040-150-R?

A: The DR1040-150-R has a higher current rating (3.1 A versus 2.8 A) and higher DC resistance (50 mOhm Max versus 37 mOhm Max). Physical dimensions are slightly larger (10.50mm × 10.30mm versus 10.00mm × 10.00mm). The inductance value and tolerance remain equivalent at 15 µH ±30%.

Q: Does increased DC resistance affect circuit performance?

A: DC resistance directly impacts power dissipation and voltage drop across the inductor. The DR1040-150-R exhibits 35% higher DCR than the PM104SH-150-RC. Applications sensitive to resistive losses require evaluation of this parameter difference.

Q: Are all three parts ROHS3 compliant?

A: Yes. PM104SH-150-RC, SRU1038-150Y, and DR1040-150-R are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the ±30% inductance tolerance?

A: The ±30% tolerance defines the acceptable inductance range for all three parts. At 15 µH nominal, actual inductance may vary between 10.5 µH and 19.5 µH. Applications requiring tighter inductance control should specify parts with narrower tolerance specifications.

Q: Can DR1040-150-R be used in space-constrained applications?

A: The DR1040-150-R has a smaller seated height (4.00mm versus 4.10mm) but larger lateral dimensions (10.50mm × 10.30mm versus 10.00mm × 10.00mm). PCB layout constraints must be evaluated for each application.
