Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-3.0-47 is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 47 µH
• Current rating: 3 A minimum
• DC resistance: 50mOhm maximum
• Core material: Iron Powder
• Shielding configuration: Unshielded
• Operating temperature range: -40°C ~ 125°C minimum
• Mounting type: Surface Mount
• Physical footprint compatibility: Nonstandard package with dimensions 17.80mm x 17.00mm

The SH50S-3.0-47 meets all electrical specifications and physical constraints required for direct substitution. Differences in product status, packaging format, and moisture sensitivity level do not affect functional equivalence in the circuit.

Parameter Comparison

Engineering Selection Recommendations

The SH50S-3.0-47 is a direct functional equivalent to the obsolete SWS-3.0-47. Both components are manufactured by Amgis, LLC and share identical electrical specifications across inductance, current rating, DC resistance, and operating temperature range. The substitute part is currently in active production status with confirmed inventory availability.

The height dimension of the SH50S-3.0-47 is 11.45mm (maximum seated height) compared to 11.05mm for the SWS-3.0-47, representing a 0.40mm variance. This difference is within typical PCB assembly tolerances for surface mount components and does not impact functional performance or circuit operation.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The substitute part is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SH50S-3.0-47 be used as a direct replacement for the SWS-3.0-47 in existing designs?

A: Yes. The SH50S-3.0-47 meets all electrical and mechanical specifications required for functional equivalence. The inductance value, current rating, DC resistance, core material, and operating temperature range are identical. The physical footprint is compatible within standard PCB assembly tolerances.

Q: What is the significance of the height dimension difference between these parts?

A: The SH50S-3.0-47 has a maximum seated height of 11.45mm versus 11.05mm for the SWS-3.0-47. This 0.40mm difference is within typical surface mount assembly tolerances and does not affect circuit performance or PCB layout compatibility.

Q: Why is the SWS-3.0-47 listed as obsolete?

A: The SWS-3.0-47 has been discontinued by the manufacturer. The SH50S-3.0-47 represents the current production equivalent from Amgis, LLC and is actively manufactured and stocked.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance status is identical between the main part and substitute.

Q: What packaging formats are available for the substitute part?

A: The SH50S-3.0-47 is supplied in Tape & Reel (TR) packaging, optimized for automated pick-and-place assembly operations.
