SWS-2.74-24 Equivalent & Substitute Parts

Part Overview

The SWS-2.74-24 is a 24 µH unshielded toroidal inductor manufactured by Amgis, LLC, designed for surface mount applications. This fixed inductor is rated for 2.74 A continuous current with a DC resistance of 70mOhm and operates across the temperature range of -40°C to 125°C. The component is ROHS3 compliant and classified as Active product status. Substitute parts are identified when electrical specifications, mechanical dimensions, and compliance certifications align within acceptable tolerances for the application.

Key Parameters

Substitute Part Grouping Explanation

The SH150S-2.74-24 qualifies as a direct substitute for the SWS-2.74-24 based on the following critical parameters:

• Inductance value: 24 µH (identical)
• Inductance tolerance: ±20% (identical)
• Current rating: 2.74 A (identical)
• DC resistance: 70mOhm (identical)
• Core material: Iron Powder (identical)
• Shielding configuration: Unshielded (identical)
• Operating temperature range: -40°C to 125°C (identical)
• Mounting type: Surface Mount (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• REACH status: REACH Unaffected (identical)

Mechanical dimensions and height specifications differ between the two parts. The SH150S-2.74-24 exhibits slightly larger footprint dimensions (15.60mm L × 15.00mm W versus 15.00mm L × 15.00mm W) and greater seated height (9.85mm versus 8.25mm). These dimensional variations must be evaluated against specific PCB layout constraints and available mounting space in the target application.

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-2.74-24 and SH150S-2.74-24 maintain Active product status from Amgis, LLC and satisfy ROHS3 compliance requirements. Selection between these parts depends on PCB layout constraints and available vertical clearance. The SWS-2.74-24 offers a more compact profile with maximum seated height of 8.25mm and smaller footprint dimensions. The SH150S-2.74-24 provides identical electrical performance with slightly increased physical dimensions (15.60mm length, 9.85mm height). The SH150S-2.74-24 carries MSL rating of 2 (1 Year) compared to MSL 1 (Unlimited) for the SWS-2.74-24, which affects moisture handling and storage requirements. Both parts are suitable for applications requiring 24 µH inductance at 2.74 A continuous current with 70mOhm DC resistance across the -40°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution between SWS-2.74-24 and SH150S-2.74-24?

A: The inductance value (24 µH), current rating (2.74 A), DC resistance (70mOhm), core material (Iron Powder), shielding configuration (Unshielded), and operating temperature range (-40°C to 125°C) must remain identical. Both parts meet these requirements.

Q: Are there dimensional differences between these substitute parts?

A: Yes. The SWS-2.74-24 measures 15.00mm L × 15.00mm W × 8.25mm H (seated). The SH150S-2.74-24 measures 15.60mm L × 15.00mm W × 9.85mm H (seated). PCB layout and available mounting space must accommodate these variations.

Q: Do both parts have the same moisture sensitivity rating?

A: No. The SWS-2.74-24 carries MSL 1 (Unlimited), while the SH150S-2.74-24 carries MSL 2 (1 Year). This affects storage conditions and handling procedures. MSL 2 components require controlled humidity storage and have a one-year shelf life from the date of manufacture.

Q: Are both parts RoHS compliant?

A: Yes. Both the SWS-2.74-24 and SH150S-2.74-24 are ROHS3 compliant and REACH unaffected.

Q: Can these parts be used interchangeably in all applications?

A: Electrical substitution is valid when inductance, current rating, DC resistance, and temperature range requirements are met. Physical substitution requires verification that PCB layout accommodates the dimensional differences, particularly the increased height of the SH150S-2.74-24.
