24220C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 24220C is a 22 µH unshielded wirewound inductor rated for 1.11 A with a maximum DC resistance of 180mOhm. This surface mount component operates across the -40°C to 85°C temperature range and is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductance value and current rating category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24220C is determined by the following critical parameters:

Inductance Value: 22 µH (exact match required)

Current Rating: Minimum 1.1 A (substitute must support the application current demand)

DC Resistance: Maximum 190mOhm (within acceptable operating margin for power loss characteristics)

Shielding Configuration: Unshielded (maintains electromagnetic compatibility profile)

Mounting Type: Surface Mount (ensures mechanical compatibility with PCB assembly)

Operating Temperature Range: Minimum -40°C to 85°C coverage (substitute must support or exceed the specified range)

Compliance: RoHS3 and REACH Unaffected status (regulatory requirement match)

The Bourns Inc. SDR0604-220YL meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 24220C and SDR0604-220YL maintain Active product status with full RoHS3 and REACH compliance. The SDR0604-220YL provides an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C), which offers additional thermal margin in applications requiring sustained operation at elevated temperatures. The DCR specification of the SDR0604-220YL (190mOhm Max) remains within acceptable tolerance relative to the 24220C (180mOhm Max). Both components are surface mount, unshielded wirewound inductors with identical 22 µH inductance values and comparable current ratings. Physical dimensions show minor variations in width and height; PCB layout verification is necessary to confirm mechanical fit within the target assembly.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-220YL directly replace the 24220C in existing designs?

A: Direct substitution is possible when the following conditions are met: PCB footprint accommodates the SDR0604-220YL dimensions (5.80mm x 5.80mm x 4.80mm max height versus 5.80mm x 5.20mm x 4.50mm max height for the 24220C), the application current does not exceed 1.1 A, and the circuit design accepts the 190mOhm maximum DCR specification.

Q: What is the significance of the DC Resistance difference between these parts?

A: The 24220C specifies 180mOhm Max while the SDR0604-220YL specifies 190mOhm Max. This 10mOhm difference affects power dissipation characteristics. In applications where DCR is critical to thermal performance or efficiency, this variance must be evaluated against circuit requirements.

Q: Are there packaging differences between these inductors?

A: The 24220C is supplied in Tape & Reel (TR) packaging, while the SDR0604-220YL is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are suitable for automated assembly; procurement and handling processes may differ based on packaging format.

Q: Does the extended temperature range of the SDR0604-220YL provide any advantage?

A: The SDR0604-220YL operates to 125°C versus 85°C for the 24220C. Applications requiring operation at elevated ambient temperatures or with thermal margin considerations may benefit from this extended range.

Q: What physical constraints should be verified before substitution?

A: The SDR0604-220YL is 0.228" x 0.228" (5.80mm x 5.80mm) with 0.189" (4.80mm) maximum seated height, compared to the 24220C at 0.228" x 0.205" (5.80mm x 5.20mm) with 0.177" (4.50mm) maximum seated height. Verify PCB layout clearances and component placement density to confirm mechanical compatibility.
