PM32-5R6M-RC Equivalent & Substitute Parts

Part Overview

The PM32-5R6M-RC is a 5.6 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.1 A continuous current with a maximum DC resistance of 160mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the same performance envelope.

Substitute Part Grouping Explanation

Substitution of the PM32-5R6M-RC with the SDR0302-5R6ML is based on strict equivalence across all critical electrical and mechanical parameters. Both components share identical specifications for inductance value (5.6 µH), current rating (1.1 A), saturation current (1.3 A), DC resistance (160mOhm maximum), core material (ferrite), shielding configuration (unshielded), quality factor (18 @ 7.96MHz), self-resonant frequency (42MHz), operating temperature range (-40°C to 125°C), physical dimensions (3.00mm x 2.80mm), and mounting type (surface mount). Both parts maintain ROHS3 compliance and MSL Level 1 classification. The substitution is valid where the PM32 series can be replaced with the SDR0302 series without functional or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the PM32-5R6M-RC and SDR0302-5R6ML are Active status products manufactured by Bourns Inc. with full ROHS3 compliance and REACH unaffected classification. Selection between these parts is determined by availability and supply chain requirements rather than technical performance differences. The SDR0302-5R6ML currently maintains higher inventory availability (3255 pcs) compared to the PM32-5R6M-RC (1154 pcs). Both components are suitable for direct substitution in applications requiring 5.6 µH inductance at 1.1 A continuous current with surface mount integration.

Frequently Asked Questions (FAQ)

Q: Can the SDR0302-5R6ML replace the PM32-5R6M-RC in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including inductance, current rating, DC resistance, core material, physical dimensions, and operating temperature range. Direct substitution is valid without circuit redesign.

Q: Are there differences in package footprint between these parts?

A: No. Both components share identical physical dimensions of 3.00mm length by 2.80mm width with a maximum seated height of 2.80mm, ensuring compatibility with the same PCB layout and assembly processes.

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

A: The ±20% tolerance defines the acceptable range of inductance variation from the nominal 5.6 µH value. Both substitute parts maintain this tolerance specification, ensuring equivalent circuit performance within the design margin.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PM32-5R6M-RC and SDR0302-5R6ML are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (unlimited moisture sensitivity protection), meeting identical regulatory and environmental requirements.

Q: What is the maximum continuous current these inductors support?

A: Both parts are rated for 1.1 A continuous current with a saturation current (Isat) of 1.3 A. Operating above the continuous current rating or approaching saturation current will result in inductance degradation and increased core losses.
