SWS-3.00-77 Equivalent & Substitute Parts

Part Overview

The SWS-3.00-77 is a 77 µH unshielded toroidal inductor manufactured by Amgis, LLC, designed for surface mount applications requiring 3 A current handling capability with 80mOhm DC resistance. This component is classified as Active product status with ROHS3 compliance and operates across the industrial temperature range of -40°C to 125°C. Substitute parts are identified to provide design flexibility, inventory alternatives, and continuity of supply for applications where the primary part becomes unavailable or where mechanical envelope constraints permit dimensional variation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-3.00-77 is determined by strict equivalence across the following critical electrical parameters: inductance value (77 µH), inductance tolerance (±20%), current rating (3 A), and DC resistance (80mOhm). The core material (iron powder), shielding configuration (unshielded), and operating temperature range (-40°C to 125°C) must remain constant. All substitute parts must maintain surface mount capability and nonstandard package classification. Compliance certifications including ROHS3 and REACH Unaffected status are mandatory for substitution validity. The SH150S-3.00-77 meets all electrical and environmental criteria for direct substitution, with mechanical dimensions representing the only variance within acceptable tolerances for nonstandard toroidal inductor packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-3.00-77 and SH150S-3.00-77 are Active status components manufactured by Amgis, LLC with identical electrical specifications and full regulatory compliance. Selection between these parts is based on mechanical envelope constraints and moisture handling requirements. The SWS-3.00-77 features a taller profile (0.506" seated height) with MSL 1 moisture sensitivity, suitable for applications with unlimited shelf life requirements and vertical space availability. The SH150S-3.00-77 provides a lower profile (0.427" seated height) with MSL 2 moisture sensitivity, appropriate for space-constrained designs where 1-year moisture exposure control is acceptable. Length dimension variance (0.032" difference) must be evaluated against PCB layout constraints. Both parts maintain identical electrical performance across the specified operating temperature range and current ratings.

Frequently Asked Questions (FAQ)

Q: Can SH150S-3.00-77 be used as a direct replacement for SWS-3.00-77 in all applications?

A: Electrical substitution is valid. Mechanical compatibility must be confirmed. The SH150S-3.00-77 is 0.079" shorter in height and 0.032" longer in length. PCB layout and component clearance must accommodate these dimensional changes.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: SWS-3.00-77 carries MSL 1 (unlimited shelf life without moisture control). SH150S-3.00-77 carries MSL 2 (1-year shelf life with moisture control). Storage and handling procedures differ accordingly. MSL 2 components require desiccant packaging and controlled humidity environments.

Q: Are both parts suitable for the same current and temperature operating conditions?

A: Yes. Both parts are rated for 3 A continuous current and operate across -40°C to 125°C. DC resistance and inductance characteristics are identical at the 10 kHz test frequency.

Q: What compliance certifications apply to both substitute parts?

A: Both parts are ROHS3 compliant and REACH Unaffected. Packaging format is Tape & Reel (TR) for both components. ECCN classification is EAR99 for both parts.

Q: How do the series designations (SW vs. SH150) affect substitution?

A: Series designation reflects internal Amgis, LLC product line organization. Electrical and environmental specifications are the determining factors for substitution validity, not series nomenclature. Both parts meet identical electrical and compliance requirements.
