PM124SH-220M-RC Equivalent & Substitute Parts

Part Overview

The PM124SH-220M-RC is a 22 µH shielded drum core wirewound inductor manufactured by Bourns Inc., rated for 3 A continuous current with a maximum DC resistance of 67.5 mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is ROHS3 compliant. The part is currently in active production status with substantial inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, supply chain optimization, or packaging format preferences.

Substitute Part Grouping Explanation

The SRR1240-220M qualifies as a direct substitute for the PM124SH-220M-RC based on strict electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

• Inductance value: 22 µH (identical)
• Inductance tolerance: ±20% (identical)
• Current rating: 3 A (identical)
• Saturation current: 2.6 A (identical)
• DC resistance: 67.5 mOhm Max (identical)
• Core type: Ferrite drum core, wirewound (identical)
• Shielding: Shielded (identical)
• Operating temperature range: -40°C to 125°C (identical)
• Physical dimensions: 12.50 mm x 12.50 mm x 4.50 mm max height (identical)
• Mounting type: Surface mount (identical)
• Compliance: ROHS3 compliant, MSL 1 (identical)

The primary difference between these parts is packaging format: PM124SH-220M-RC is supplied in Cut Tape (CT) & Digi-Reel format, while SRR1240-220M is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both PM124SH-220M-RC and SRR1240-220M are active production components from Bourns Inc. with identical electrical specifications and mechanical dimensions. Selection between these parts should be based on packaging and supply requirements:

• PM124SH-220M-RC: Select when Cut Tape or Digi-Reel packaging is required for lower-volume applications or manual assembly processes.
• SRR1240-220M: Select when Tape & Reel packaging is required for high-volume automated assembly operations.

Both parts meet ROHS3 compliance and carry MSL 1 rating, indicating no moisture sensitivity restrictions. Inventory availability is confirmed for both variants, with SRR1240-220M showing higher stock levels (2355 pcs vs. 1345 pcs).

Frequently Asked Questions (FAQ)

Q: Can SRR1240-220M be used as a direct replacement for PM124SH-220M-RC in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, and performance characteristics are identical. The only difference is packaging format. If your assembly process accommodates Tape & Reel format, substitution is valid without design modification.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) & Digi-Reel format is suitable for lower-volume applications and manual pick-and-place operations. Tape & Reel (TR) format is optimized for high-volume automated assembly lines with continuous feeder compatibility.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. Both parts operate identically across the -40°C to 125°C temperature range with identical Q factor (18 @ 2.52 MHz) and self-resonant frequency (16 MHz).

Q: Do both parts meet the same compliance standards?

A: Yes. Both PM124SH-220M-RC and SRR1240-220M are ROHS3 compliant with MSL 1 rating and REACH unaffected status.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing volume and assembly capability. For automated high-volume production, SRR1240-220M (Tape & Reel) is standard. For lower volumes or manual assembly, PM124SH-220M-RC (Cut Tape) may be more practical.
