PM32-150M-RC Equivalent & Substitute Parts

Part Overview

The PM32-150M-RC is a 15 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., designed for surface mount applications. This component is rated for 650 mA continuous current with a maximum DC resistance of 400 mOhm and operates across the temperature range of -40°C to 125°C. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across critical parameters including inductance value, current rating, DC resistance, core material, shielding configuration, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM32-150M-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 15 µH with ±20% tolerance
• Current rating: 650 mA minimum continuous current capability
• DC resistance: 400 mOhm maximum
• Core material and type: Ferrite drum core, wirewound, unshielded configuration
• Physical dimensions: 3.00 mm x 2.80 mm x 2.80 mm maximum
• Surface mount packaging in tape and reel format
• Operating temperature range: -40°C to 125°C minimum
• Regulatory compliance: ROHS3 and REACH requirements

The SDR0302-150ML meets all specified electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the PM32-150M-RC and SDR0302-150ML are active production components from Bourns Inc. with identical electrical specifications and physical form factors. Selection between these parts may be based on inventory availability and supply chain considerations. The PM32-150M-RC currently maintains 1,022 units in stock, while the SDR0302-150ML has 3,327 units available. Both components satisfy ROHS3 compliance and REACH requirements for regulated markets. The SDR0302-150ML represents an equivalent alternative with no functional or performance trade-offs.

Frequently Asked Questions (FAQ)

Q: Can the SDR0302-150ML be used as a direct replacement for the PM32-150M-RC in existing designs?

A: Yes. The SDR0302-150ML is electrically and mechanically equivalent across all specified parameters including inductance, current rating, DC resistance, core material, physical dimensions, and operating temperature range. No circuit modifications are required.

Q: Are there differences in the package or mounting between these parts?

A: No. Both parts use identical surface mount packaging in tape and reel format with matching physical dimensions of 3.00 mm x 2.80 mm x 2.80 mm. PCB footprints and reflow profiles remain unchanged.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the PM32-150M-RC and SDR0302-150ML are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (unlimited).

Q: What is the basis for substitution between these two part numbers?

A: Substitution is based on complete equivalence across critical electrical parameters (inductance, current rating, DC resistance, Q factor, self-resonant frequency) and mechanical specifications (core material, shielding, dimensions, mounting type). Both parts are manufactured by Bourns Inc. and maintain identical performance characteristics.

Q: Are there any performance differences in frequency response or impedance characteristics?

A: No. Both parts exhibit identical Q factor of 20 at 2.52 MHz and self-resonant frequency of 32 MHz. Frequency-dependent behavior is equivalent.
