SWT-1.87-53 Equivalent & Substitute Parts

Part Overview

The SWT-1.87-53 is a 53 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 1.87 A continuous current with 130mOhm DC resistance. This through-hole component operates across -40°C to 125°C and is ROHS3 compliant. The part remains in active production status with 946 units currently in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging preferences, or application-specific mounting requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the SWT-1.87-53 is determined by strict equivalence across the following critical parameters:

• Inductance value: 53 µH with ±20% tolerance
• Current rating: 1.87 A minimum
• DC resistance: 130mOhm
• Core material: Iron Powder
• Shielding configuration: Unshielded
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: Through Hole
• Compliance: ROHS3 and REACH Unaffected status

The SH150T-1.87-53 meets all electrical equivalence criteria. Differences in package case geometry (Radial, Horizontal - Corner Terminals vs. Radial, Horizontal Open) and packaging format (Tray vs. Bulk) do not affect electrical performance or functional compatibility in applications where the inductor's electrical characteristics are the primary selection criterion.

Parameter Comparison

Engineering Selection Recommendations

Both the SWT-1.87-53 and SH150T-1.87-53 are active production components from Amgis, LLC with identical electrical specifications and full compliance with ROHS3 and REACH requirements. Selection between these parts is based on application-specific factors:

The SWT-1.87-53 with radial horizontal open terminals and bulk packaging is suitable for applications where standard radial lead geometry and bulk component sourcing are preferred.

The SH150T-1.87-53 with corner terminals and tray packaging is suitable for applications where corner terminal geometry provides improved mechanical stability or where tray packaging aligns with assembly and inventory management workflows.

Both parts deliver equivalent electrical performance in circuits requiring 53 µH inductance at 1.87 A with 130mOhm DC resistance across the -40°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Are the SWT-1.87-53 and SH150T-1.87-53 electrically interchangeable?

A: Yes. Both parts have identical inductance (53 µH), current rating (1.87 A), DC resistance (130mOhm), core material (iron powder), and operating temperature range (-40°C to 125°C). Electrical performance is equivalent.

Q: What is the difference between radial horizontal open and corner terminals?

A: Radial horizontal open terminals extend from the toroid body in a standard radial configuration. Corner terminals are positioned at the corners of the component body. This affects PCB footprint layout and mechanical mounting geometry but does not impact electrical characteristics.

Q: Can I use SH150T-1.87-53 in place of SWT-1.87-53 on an existing PCB?

A: Physical compatibility depends on PCB footprint design. The SH150T-1.87-53 has slightly larger dimensions (0.614" L vs. 0.591" L and 0.358" height vs. 0.346" height) and different terminal positioning. Verify PCB layout accommodates the corner terminal geometry and increased dimensions before substitution.

Q: What is the difference between bulk and tray packaging?

A: Bulk packaging supplies loose components, while tray packaging organizes components in segmented trays for automated assembly equipment. Packaging format does not affect component electrical performance or functional compatibility.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the SWT-1.87-53 and SH150T-1.87-53 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component use.
