Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SWS-0.20-374 are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 374 µH
• Inductance tolerance: ±20%
• Current rating: 200 mA
• DC resistance: 2.7Ohm
• Mounting type: Surface Mount
• Type: Toroidal

Acceptable Variations:

• Shielding configuration (unshielded to shielded transition acceptable for EMI-sensitive applications)
• Operating temperature range (minimum -40°C, maximum ≥125°C)
• Physical dimensions (within nonstandard package constraints)
• Moisture sensitivity level (MSL 1 or MSL 2 acceptable)

Two substitute parts meet these criteria: SH150S-0.20-374 (Amgis, LLC) and PE-53808SNL (Pulse Electronics).

Parameter Comparison

Engineering Selection Recommendations

SH150S-0.20-374 (Amgis, LLC): This part is the primary substitute for the obsolete SWS-0.20-374. It maintains identical electrical specifications and operating temperature range. The SH150S series is active and available in production quantities. Physical dimensions are slightly larger (11.20mm x 11.00mm vs. 10.00mm x 10.00mm), requiring PCB layout verification. Moisture sensitivity is MSL 2, requiring controlled storage conditions. This part is suitable for applications where unshielded inductors are specified.

PE-53808SNL (Pulse Electronics): This part provides an alternative from a different manufacturer with identical electrical specifications. The key distinction is shielded construction, which provides EMI containment benefits. Operating temperature range extends to 130°C, offering additional thermal margin. Physical height is greater (9.14mm vs. 6.75mm), requiring clearance verification. Moisture sensitivity is MSL 1, eliminating storage constraints. This part is recommended for noise-sensitive applications or where EMI performance is critical.

Frequently Asked Questions (FAQ)

Q: Can SH150S-0.20-374 directly replace SWS-0.20-374 in existing designs?

A: Electrical substitution is direct. Physical dimensions differ: SH150S-0.20-374 is 11.20mm x 11.00mm x 7.65mm versus SWS-0.20-374 at 10.00mm x 10.00mm x 6.75mm. PCB layout and clearance must be verified before implementation.

Q: What is the difference between the unshielded SH150S-0.20-374 and shielded PE-53808SNL?

A: Both parts have identical inductance, current rating, and DC resistance. PE-53808SNL includes shielding for EMI containment. Shielding increases height to 9.14mm. Select based on EMI requirements and available PCB clearance.

Q: Are there storage or handling differences between these substitutes?

A: SWS-0.20-374 and PE-53808SNL are MSL 1 (unlimited shelf life). SH150S-0.20-374 is MSL 2, requiring storage at ≤30°C and ≤60% relative humidity with a 1-year floor life after bag opening.

Q: Do all three parts meet current compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: Which substitute offers the best long-term availability?

A: Both SH150S-0.20-374 and PE-53808SNL are active products. SH150S-0.20-374 maintains Amgis, LLC manufacturing continuity. PE-53808SNL provides supply diversification through Pulse Electronics.
