SWC-3.0-330 Equivalent & Substitute Parts

Part Overview

The SWC-3.0-330 is a 330 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 3 A continuous current with a maximum DC resistance of 150 mOhm. This through-hole component operates across the industrial temperature range of -40°C to 125°C and is designed for applications requiring fixed inductance in compact radial configurations. The part maintains Active product status with ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when electrical specifications, mechanical dimensions, and compliance certifications remain equivalent across alternative packaging or series designations.

Substitute Part Grouping Explanation

The SH50C-3.0-330 qualifies as a direct electrical and mechanical substitute for the SWC-3.0-330 based on the following equivalence criteria:

Electrical Parameters (Identical):

• Inductance: 330 µH at ±20% tolerance
• Current Rating: 3 A
• DC Resistance: 150 mOhm maximum
• Core Material: Iron Powder
• Shielding Classification: Unshielded
• Test Frequency: 10 kHz
• Operating Temperature: -40°C to 125°C

Mechanical Parameters (Identical):

• Mounting Type: Through Hole
• Package Configuration: Radial, Vertical (Open)
• Physical Dimensions: 1.252" L × 0.701" W (31.80 mm × 17.81 mm)
• Seated Height: 1.382" (35.10 mm maximum)

Compliance & Certification (Equivalent):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• ECCN Classification: EAR99
• HTSUS Code: 8504.50.4000

The substitution is based on series designation change (SW to SH50) and packaging format change (Bulk to Tray) while maintaining complete electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SWC-3.0-330 and SH50C-3.0-330 maintain Active product status from Amgis, LLC and satisfy identical electrical and mechanical requirements for 330 µH toroidal inductor applications at 3 A. Selection between these parts is determined by packaging requirements: the SWC-3.0-330 is supplied in Bulk packaging, while the SH50C-3.0-330 is supplied in Tray packaging. Both parts carry ROHS3 compliance and REACH unaffected certification, making them suitable for regulated applications. The choice between series designations (SW versus SH50) does not affect functional performance, as all critical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can the SH50C-3.0-330 be used as a direct replacement for the SWC-3.0-330 in existing designs?

A: Yes. The SH50C-3.0-330 is electrically and mechanically equivalent to the SWC-3.0-330. All inductance, current rating, DC resistance, dimensional, and temperature specifications are identical. The parts differ only in series designation and packaging format.

Q: What is the difference between Bulk and Tray packaging for these inductors?

A: Bulk packaging supplies components without organized trays, typically for high-volume applications. Tray packaging organizes components in structured trays for automated assembly and inventory management. The electrical and mechanical performance of the inductor remains unchanged regardless of packaging format.

Q: Are both parts compliant with RoHS and REACH regulations?

A: Yes. Both the SWC-3.0-330 and SH50C-3.0-330 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What determines whether these parts can substitute for one another?

A: Substitution is based on matching inductance value (330 µH), inductance tolerance (±20%), current rating (3 A), DC resistance (150 mOhm maximum), core material (Iron Powder), shielding type (Unshielded), mounting configuration (Through Hole, Radial Vertical Open), physical dimensions, and operating temperature range (-40°C to 125°C). Both parts meet all these criteria.

Q: Can these inductors be used in applications requiring shielded inductors?

A: No. Both the SWC-3.0-330 and SH50C-3.0-330 are unshielded inductors. Applications requiring shielded inductors require alternative part selection.

Q: What is the maximum continuous current these inductors can handle?

A: Both inductors are rated for 3 A continuous current at the specified operating temperature range of -40°C to 125°C.
