SWS6-1.4-220 Equivalent & Substitute Parts

Part Overview

The SWS6-1.4-220 is a 220 µH unshielded toroidal inductor manufactured by Amgis, LLC, designed for surface mount applications. This component is rated for 1.4 A continuous current with a maximum DC resistance of 140mOhm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification.

Substitute parts become necessary when the primary component faces inventory constraints, extended lead times, or when design flexibility permits inductance value variation within acceptable circuit tolerances. The SWS6-1.4-220 has been identified with one direct substitute option that maintains critical electrical parameters while offering alternative mechanical packaging.

Key Parameters

Substitute Part Grouping Explanation

The SH50S-1.4-176 qualifies as a direct substitute based on the following alignment of critical parameters:

Maintained Electrical Specifications:

• Current Rating: 1.4 A (identical)
• DC Resistance: 140mOhm Max (identical)
• Operating Temperature: -40°C to 125°C (identical)
• Core Material: Iron Powder (identical)
• Shielding: Unshielded (identical)
• RoHS Status: ROHS3 Compliant (identical)

Inductance Variation: The SH50S-1.4-176 provides 176 µH inductance compared to the primary part's 220 µH. This 20% reduction falls within the ±20% tolerance band of the SWS6-1.4-220, making it electrically interchangeable for circuits designed to accept this tolerance range.

Mechanical Differences: Physical dimensions and height vary between the two parts. The SH50S-1.4-176 measures 24.30mm L x 24.60mm W with a seated height of 10.45mm, compared to the SWS6-1.4-220 at 24.60mm L x 24.60mm W with a seated height of 13.75mm. These differences require PCB layout verification before substitution.

Parameter Comparison

Engineering Selection Recommendations

The SH50S-1.4-176 is suitable as a substitute for the SWS6-1.4-220 when the following conditions are met:

Electrical Compatibility: Circuit design must accommodate the 176 µH inductance value. Applications with inductance tolerance specifications of ±20% or greater will accept this substitute without performance degradation. The identical current rating, DC resistance, and operating temperature range ensure thermal and electrical performance equivalence.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent product substitution in compliant applications.

Mechanical Considerations: PCB layout must be verified to accommodate the SH50S-1.4-176 dimensions. The substitute is 0.80mm longer and 3.30mm shorter in height. Verify that the increased length does not conflict with adjacent components and that the reduced height does not create clearance issues with overlying assemblies.

Packaging and Handling: The substitute arrives in Tape & Reel format with MSL 2 (1 Year) moisture sensitivity, requiring controlled storage conditions. The primary part's MSL 1 rating permits unlimited shelf life without special handling.

Frequently Asked Questions (FAQ)

Q: Can the SH50S-1.4-176 be used as a direct drop-in replacement for the SWS6-1.4-220?

A: Electrical substitution is valid based on current rating, DC resistance, and operating temperature equivalence. However, mechanical verification is required. The substitute's different dimensions (24.30mm L x 24.60mm W, 10.45mm height) must be confirmed against PCB layout constraints before implementation.

Q: What is the inductance difference between these parts, and does it matter?

A: The SH50S-1.4-176 provides 176 µH compared to the SWS6-1.4-220's 220 µH, representing a 20% reduction. This difference falls within the ±20% tolerance specification of the primary part. Circuit performance impact depends on application sensitivity to inductance variation. Applications with tight inductance requirements should evaluate circuit behavior at 176 µH before substitution.

Q: Are there compliance differences between these parts?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. The primary difference is moisture sensitivity level: the SWS6-1.4-220 is MSL 1 (unlimited shelf life), while the SH50S-1.4-176 is MSL 2 (1 year maximum storage). The substitute requires controlled storage conditions to maintain performance specifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: current rating (1.4 A maintained), DC resistance (140mOhm Max maintained), operating temperature range (-40°C to 125°C maintained), core material (Iron Powder maintained), shielding type (Unshielded maintained), and inductance tolerance (176 µH within ±20% of 220 µH specification). Mechanical dimensions must be verified separately for PCB compatibility.

Q: How do the different inductance test frequencies affect substitution?

A: The SWS6-1.4-220 is tested at 20 kHz while the SH50S-1.4-176 is tested at 10 kHz. These different measurement conditions reflect standard industry practice for component characterization. Both parts operate across the same frequency range in actual circuit applications. The inductance values provided are valid for their respective test frequencies and represent the component's performance characteristics.
