SWS-0.68-377 Equivalent & Substitute Parts

Part Overview

The SWS-0.68-377 is a 377 µH unshielded toroidal inductor manufactured by Amgis, LLC, designed for surface mount applications with a current rating of 680 mA and 1 Ohm DC resistance. This component is classified as Active status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs, particularly when inventory availability or specific shielding requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-0.68-377 is determined by the following critical parameters:

• Inductance Value: 377 µH (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Current Rating: 680 mA (minimum requirement)
• DC Resistance: 1 Ohm (exact match required)
• Mounting Type: Surface Mount (physical compatibility)
• Package Classification: Nonstandard (dimensional compatibility within tolerance)
• Compliance: RoHS3 and REACH status alignment

The PE-53826SNL qualifies as a direct substitute based on matching inductance, tolerance, current rating, and DC resistance specifications. Dimensional variations and shielding differences are secondary considerations that do not preclude substitution when primary electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-0.68-377 and PE-53826SNL meet the core electrical requirements for 377 µH toroidal inductor applications at 680 mA. Selection between these parts should be based on:

SWS-0.68-377 (Amgis, LLC): Choose when unshielded inductor characteristics are required and compact form factor (8.25mm height) is advantageous. Active product status with 1015 units in stock.

PE-53826SNL (Pulse Electronics): Choose when shielded inductor performance is required to minimize electromagnetic interference, or when the extended operating temperature range to 130°C is necessary. Active product status with 1970 units in stock. Note the increased height (9.91mm) and slightly larger footprint dimensions.

Both parts carry identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can PE-53826SNL replace SWS-0.68-377 in all applications?

A: PE-53826SNL matches all critical electrical parameters (377 µH inductance, 680 mA current rating, 1 Ohm DCR, ±20% tolerance). The primary difference is shielding: PE-53826SNL is shielded while SWS-0.68-377 is unshielded. Substitution is valid when shielding does not negatively impact circuit performance. Dimensional differences (height 9.91mm vs 8.25mm, footprint 15.75mm x 15.24mm vs 15.00mm x 15.00mm) must be verified against PCB layout constraints.

Q: What is the significance of shielding in these inductors?

A: Shielding reduces electromagnetic field radiation and susceptibility to external interference. The unshielded SWS-0.68-377 is suitable for applications where EMI is not a concern. The shielded PE-53826SNL is preferred in noise-sensitive circuits or high-density PCB layouts.

Q: Are there temperature range differences between these parts?

A: SWS-0.68-377 operates from -40°C to 125°C, while PE-53826SNL extends to 130°C. For applications requiring operation above 125°C, PE-53826SNL is the appropriate choice.

Q: Do packaging differences affect substitution?

A: SWS-0.68-377 is supplied in Tape & Reel (TR) packaging, while PE-53826SNL is supplied in Bulk packaging. This affects handling and storage but does not impact electrical or mechanical compatibility. Verify that your assembly process accommodates the packaging format.

Q: Are both parts RoHS3 compliant?

A: Yes, both SWS-0.68-377 and PE-53826SNL are RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for EU and global markets.
