Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-0.54-173 is determined by the following critical parameters:

• Inductance value: 173 µH with ±20% tolerance
• Current rating: minimum 540 mA
• DC resistance: 600mOhm
• Core material: Iron Powder
• Shielding configuration: Unshielded
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: Surface Mount
• Inductance measurement frequency: 10 kHz

The substitute part SH150S-0.54-173 meets all electrical specifications and core material requirements. Mechanical dimensions differ slightly, requiring verification of PCB layout compatibility and clearance constraints specific to the application.

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-0.54-173 and SH150S-0.54-173 are active production components from Amgis, LLC with identical electrical specifications. Selection between these parts depends on application-specific constraints:

The SWS-0.54-173 features a smaller footprint (12.80mm × 12.80mm × 7.25mm maximum height) and MSL rating of 1, suitable for applications with unlimited moisture exposure tolerance and space-constrained PCB layouts.

The SH150S-0.54-173 has a larger footprint (14.20mm × 14.00mm × 8.55mm maximum height) and MSL rating of 2, requiring controlled moisture storage conditions with a one-year shelf life limit. This part is appropriate for applications where the increased dimensions do not present layout conflicts.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can SH150S-0.54-173 directly replace SWS-0.54-173 in existing designs?

A: Electrical substitution is valid based on identical inductance, current rating, DC resistance, and core material specifications. Physical substitution requires PCB layout verification due to dimensional differences. The SH150S-0.54-173 is 1.4mm longer, 1.47mm wider, and 3.0mm taller than the SWS-0.54-173.

Q: What are the critical parameters for inductor substitution?

A: Inductance value and tolerance, current rating, DC resistance, core material, shielding configuration, and operating temperature range determine substitution eligibility. All these parameters must match or exceed the original specification.

Q: Does the MSL rating difference affect substitution?

A: MSL rating indicates moisture sensitivity during storage and handling. The SWS-0.54-173 with MSL 1 has unlimited moisture tolerance, while the SH150S-0.54-173 with MSL 2 requires storage in controlled humidity conditions with a one-year shelf life. This affects supply chain handling but not circuit performance.

Q: Are both parts suitable for the full operating temperature range?

A: Both parts operate across -40°C to 125°C, meeting identical thermal specifications for industrial and commercial applications.

Q: What packaging format is used for both parts?

A: Both the SWS-0.54-173 and SH150S-0.54-173 are supplied in Tape & Reel (TR) packaging for automated assembly processes.
