SWT-0.90-330 Equivalent & Substitute Parts

Part Overview

The SWT-0.90-330 is a 330 µH unshielded toroidal inductor rated for 900 mA with a maximum DC resistance of 740mOhm. This through-hole component features an iron powder core and operates across the temperature range of -40°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

The SH50F-0.9-330 qualifies as a substitute for the SWT-0.90-330 based on the following matching electrical and core parameters:

• Inductance value: 330 µH (identical)
• Inductance tolerance: ±20% (identical)
• Current rating: 900 mA (identical)
• DC resistance: 740mOhm Max (identical)
• Core material: Iron Powder (identical)
• Shielding: Unshielded (identical)
• Operating temperature range: -40°C ~ 125°C (identical)
• Inductance test frequency: 10 kHz (identical)
• Mounting type: Through Hole (identical)

The primary difference between these parts is the package configuration: the SWT-0.90-330 uses a radial, horizontal (open) package, while the SH50F-0.9-330 uses a radial, vertical cylinder configuration with 4 leads. Both maintain equivalent electrical performance and core specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SWT-0.90-330 and SH50F-0.9-330 are active products from Amgis, LLC with identical electrical specifications and regulatory compliance. Selection between these parts depends on PCB layout constraints and available board space. The SWT-0.90-330 with its horizontal (open) radial configuration occupies a footprint of 17.80mm x 17.00mm with a seated height of 10.71mm. The SH50F-0.9-330 with its vertical cylinder configuration has a diameter of 17.00mm and a seated height of 12.50mm. Both parts maintain ROHS3 compliance and REACH unaffected status, making them suitable for equivalent circuit applications where the package orientation and height clearance are compatible with the design requirements.

Frequently Asked Questions (FAQ)

Q: Can the SH50F-0.9-330 be used as a direct replacement for the SWT-0.90-330?

A: Yes, provided that the PCB layout accommodates the different package configuration. The SH50F-0.9-330 uses a vertical cylinder orientation with 4 leads, while the SWT-0.90-330 uses a horizontal (open) radial configuration. The electrical specifications are identical, but the physical footprint and height differ.

Q: What are the key electrical parameters that must match for substitution?

A: The critical parameters are inductance (330 µH), tolerance (±20%), current rating (900 mA), DC resistance (740mOhm Max), core material (iron powder), and operating temperature range (-40°C ~ 125°C). Both parts meet these specifications identically.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with the same HTSUS code (8504.50.4000).

Q: What is the primary consideration when choosing between these substitutes?

A: The primary consideration is mechanical compatibility with the PCB layout. The SWT-0.90-330 has a maximum seated height of 10.71mm with a horizontal orientation, while the SH50F-0.9-330 has a maximum seated height of 12.50mm with a vertical orientation. Verify that the available board space and component clearance accommodate the selected package configuration.

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

A: No. The SWT-0.90-330 has a moisture sensitivity level listed as Not Applicable, while the SH50F-0.9-330 is rated at MSL 1 (Unlimited). This difference does not affect electrical substitution but may impact storage and handling procedures.
