Substitute Part Grouping Explanation

Substitution eligibility for the PM32-180M-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 18 µH with ±20% tolerance
• Current rating: 580 mA minimum continuous current capability
• Saturation current (Isat): 750 mA minimum
• DC resistance: 460 mOhm maximum
• Core material: Ferrite unshielded drum core construction
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: Surface mount
• Physical dimensions: 0.118" L x 0.110" W (3.00 mm x 2.80 mm) with 0.110" (2.80 mm) maximum seated height
• Packaging format: Tape & Reel (TR)
• Compliance: ROHS3 compliant, MSL 1

The SDR0302-180ML meets all specified electrical and mechanical parameters, confirming direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

Both the PM32-180M-RC and SDR0302-180ML are Active status components manufactured by Bourns Inc. with identical electrical specifications and mechanical dimensions. Both parts maintain ROHS3 compliance and MSL 1 rating, confirming suitability for modern manufacturing environments without moisture sensitivity constraints.

Selection between these parts may be based on inventory availability, supply chain considerations, or procurement lead times, as electrical and mechanical performance are equivalent. The SDR0302-180ML series currently maintains higher inventory levels (6715 Pcs) compared to the PM32-180M-RC series (859 Pcs).

Frequently Asked Questions (FAQ)

Q: Can SDR0302-180ML be used as a direct replacement for PM32-180M-RC in existing designs?

A: Yes. Both parts share identical inductance values (18 µH ±20%), current ratings (580 mA), saturation current (750 mA), DC resistance (460 mOhm max), core material (ferrite unshielded), operating temperature range (-40°C to 125°C), physical dimensions (0.118" L x 0.110" W, 2.80 mm height), and packaging format (Tape & Reel). No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts are ROHS3 compliant with MSL 1 rating and REACH unaffected status. Compliance profiles are identical.

Q: What is the significance of the different base product numbers (PM32 vs. SDR0302)?

A: The base product numbers indicate different product lines within the Bourns Inc. inductor portfolio. However, the specific part numbers PM32-180M-RC and SDR0302-180ML are functionally equivalent across all specified electrical and mechanical parameters.

Q: Are there any package or footprint considerations when switching between these parts?

A: No. Both parts use identical nonstandard package dimensions (0.118" L x 0.110" W with 0.110" maximum seated height) and Tape & Reel packaging format. PCB footprints and assembly processes remain unchanged.

Q: What factors should influence the selection between these two equivalent parts?

A: Selection should be based on inventory availability, supply chain lead times, and procurement cost. From an engineering perspective, both parts are fully interchangeable with no performance or compatibility differences.
