SWS-1.02-17 Equivalent & Substitute Parts

Part Overview

The SWS-1.02-17 is a 17 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 1.02 A with 100mOhm DC resistance. This component is designed for surface mount applications in nonstandard package configurations. The part is currently obsolete, making identification of equivalent and substitute components essential for ongoing production support, design updates, and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-1.02-17 is determined by the following core electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Inductance: 17 µH (exact match required)
• Current Rating: 1.02 A (minimum)
• DC Resistance: 100mOhm (exact match required)
• Tolerance: ±20% (exact match required)

Mechanical Compatibility Requirements:

• Type: Toroidal inductor
• Mounting Type: Surface Mount
• Package: Nonstandard

Environmental & Compliance Requirements:

• Operating Temperature: -40°C minimum to 125°C minimum
• RoHS3 Compliance required

Two substitute parts meet these criteria: SH150S-1.02-17 (Amgis, LLC) and PE-53816SNL (Pulse Electronics). Both maintain identical electrical specifications while differing in shielding configuration and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

SH150S-1.02-17 (Amgis, LLC): This substitute maintains identical electrical specifications and is manufactured by the same supplier as the original part. Product status is active with confirmed inventory availability. The part is ROHS3 compliant and REACH unaffected. Physical dimensions are slightly larger than the original, requiring PCB layout verification. Moisture sensitivity level is MSL 2, requiring controlled storage conditions (1 Year shelf life limit).

PE-53816SNL (Pulse Electronics): This substitute provides identical electrical performance with the addition of shielding, which may reduce electromagnetic interference in sensitive applications. Operating temperature range extends to 130°C, providing additional thermal margin. The part is ROHS3 compliant with MSL 1 rating (unlimited shelf life). Physical dimensions are comparable to SH150S-1.02-17 but with increased height (9.14mm vs. 6.75mm original), requiring PCB clearance verification.

Selection between substitutes depends on application requirements: unshielded operation with minimal height (SH150S-1.02-17) or shielded operation with extended temperature range and unlimited shelf life (PE-53816SNL).

Frequently Asked Questions (FAQ)

Q: Can SH150S-1.02-17 directly replace SWS-1.02-17 in existing designs? A: Electrical substitution is valid. Physical dimensions differ (11.20mm x 11.00mm vs. 10.00mm x 10.00mm), and height increases from 6.75mm to 7.65mm. PCB layout and clearance must be verified before implementation.

Q: What is the primary difference between SH150S-1.02-17 and PE-53816SNL? A: Both maintain identical electrical specifications (17 µH, 1.02 A, 100mOhm). PE-53816SNL includes shielding and extends operating temperature to 130°C. PE-53816SNL has greater height (9.14mm) and MSL 1 rating versus SH150S-1.02-17 MSL 2 rating.

Q: Does shielding in PE-53816SNL affect circuit performance? A: Shielding reduces electromagnetic radiation emission and susceptibility. Circuit behavior remains functionally equivalent for the specified electrical parameters. Application-specific EMI/EMC requirements determine whether shielding is beneficial.

Q: Are there packaging differences between these substitutes? A: SWS-1.02-17 uses nonstandard packaging. SH150S-1.02-17 is supplied in Tape & Reel (TR). PE-53816SNL is supplied in Bulk. Packaging affects handling, storage, and assembly processes.

Q: What is the impact of MSL rating differences? A: SWS-1.02-17 and PE-53816SNL have MSL 1 (unlimited shelf life). SH150S-1.02-17 has MSL 2 (1 year shelf life limit after bag opening). Storage and handling procedures must comply with MSL requirements to maintain component reliability.

Q: Are all three parts ROHS3 compliant? A: Yes. SWS-1.02-17, SH150S-1.02-17, and PE-53816SNL are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
