PM32-220M-RC Equivalent & Substitute Parts

Part Overview

The PM32-220M-RC is a 22 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., designed for surface mount applications. This component is rated for 520 mA continuous current with a maximum DC resistance of 660 mOhm and operates across the temperature range of -40°C to 125°C. The part is currently in active production status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, inventory management, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM32-220M-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 22 µH with ±20% tolerance
• Current rating: 520 mA minimum continuous current capability
• Saturation current (Isat): 650 mA minimum
• DC resistance: 660 mOhm maximum
• Core type: Ferrite drum core, wirewound, unshielded
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: Surface mount
• Physical dimensions: 3.00 mm L x 2.80 mm W x 2.80 mm H maximum
• Packaging format: Tape & Reel (TR)
• Compliance: ROHS3 compliant, REACH unaffected

The SDR0302-220ML meets all specified electrical and mechanical parameters and is therefore qualified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the PM32-220M-RC and SDR0302-220ML are active production components manufactured by Bourns Inc. with identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts may be based on inventory availability, lead time, or supply chain requirements. The SDR0302-220ML currently maintains higher inventory levels (16,300 pcs) compared to the PM32-220M-RC (744 pcs), which may influence procurement decisions. Both parts satisfy ROHS3 compliance and REACH unaffected status requirements. No technical performance differentiation exists between these components based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Can the SDR0302-220ML be used as a direct replacement for the PM32-220M-RC?

A: Yes. The SDR0302-220ML is electrically and mechanically equivalent to the PM32-220M-RC across all specified parameters, including inductance, current rating, DC resistance, operating temperature range, physical dimensions, and compliance certifications.

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

A: No. Both parts use identical surface mount packaging in Tape & Reel (TR) format with nonstandard case dimensions of 3.00 mm L x 2.80 mm W x 2.80 mm H maximum.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PM32-220M-RC and SDR0302-220ML are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What is the basis for substitution between these parts?

A: Substitution is based on complete equivalence of inductance value (22 µH ±20%), current ratings (520 mA continuous, 650 mA saturation), DC resistance (660 mOhm maximum), core material (ferrite drum core, wirewound, unshielded), operating temperature range (-40°C to 125°C), and physical dimensions.

Q: Are there any performance differences in Q factor or self-resonant frequency?

A: No. Both parts exhibit identical Q factor (23 @ 2.52 MHz) and self-resonant frequency (22 MHz) characteristics.
