SWS-4.9-23 Equivalent & Substitute Parts

Part Overview

The SWS-4.9-23 is a 22.8 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 4.9 A continuous current with 36mOhm DC resistance. This surface mount component operates across -40°C to 130°C and is designed for applications requiring fixed inductance in nonstandard package configurations. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when electrical parameters, mechanical compatibility, and regulatory certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-4.9-23 is determined by the following critical parameters:

• Inductance Value: 22.8 µH ±20% tolerance
• Current Rating: 4.9 A minimum
• DC Resistance: 36mOhm
• Inductor Type: Toroidal configuration
• Mounting: Surface mount capability
• Regulatory Compliance: ROHS3 and REACH compliance

Two substitute parts meet these core electrical and mechanical criteria. The SH260S-4.9-23 from Amgis, LLC maintains identical inductance, current rating, and DCR specifications with comparable dimensional characteristics. The P0841SNL from Pulse Electronics matches all electrical parameters but introduces shielding, which represents a functional enhancement rather than a limitation for unshielded applications.

Parameter Comparison

Engineering Selection Recommendations

SH260S-4.9-23: This substitute maintains identical electrical specifications and operates within the same temperature range as the original SWS-4.9-23. Both parts are manufactured by Amgis, LLC and carry ROHS3 compliance. The primary distinction is physical dimension reduction and MSL rating change from 1 to 2. Selection of this substitute is appropriate when space constraints favor the smaller footprint (24.30mm × 24.60mm versus 30.99mm × 27.00mm) and moisture sensitivity requirements permit a one-year shelf life limitation.

P0841SNL: This Pulse Electronics substitute provides identical electrical performance with shielded construction. The shielded design offers electromagnetic interference mitigation not present in the unshielded original. Operating temperature range matches the SWS-4.9-23 at -40°C to 130°C, and MSL rating remains at level 1. Packaging format differs (Tube versus Tape & Reel), which may affect procurement and assembly workflows. Selection is appropriate when EMI reduction is beneficial or when tube packaging aligns with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SH260S-4.9-23 be used as a direct replacement for SWS-4.9-23?

A: Yes. Both parts share identical inductance (22.8 µH), current rating (4.9 A), and DC resistance (36mOhm). The SH260S-4.9-23 operates to 125°C versus 130°C maximum, which is acceptable for most applications. Physical dimensions are smaller, requiring PCB layout verification. MSL rating of 2 requires one-year shelf life management.

Q: What is the functional difference between the unshielded SWS-4.9-23 and shielded P0841SNL?

A: Shielding in the P0841SNL reduces electromagnetic field radiation and susceptibility to external interference. Electrical parameters remain identical. Shielded inductors are suitable for noise-sensitive circuits; unshielded designs are appropriate for applications without EMI constraints.

Q: Are there packaging compatibility concerns with P0841SNL?

A: Yes. The P0841SNL is supplied in Tube packaging, while the SWS-4.9-23 uses Tape & Reel format. Tube packaging requires manual handling during assembly, whereas Tape & Reel integrates with automated pick-and-place equipment. Verify assembly process compatibility before selection.

Q: Do all three parts meet regulatory requirements?

A: All three parts are ROHS3 compliant and REACH unaffected. MSL ratings differ: SWS-4.9-23 and P0841SNL are MSL 1 (unlimited storage), while SH260S-4.9-23 is MSL 2 (one-year maximum shelf life at specified humidity). Select based on storage and handling capabilities.

Q: What determines whether a part qualifies as a substitute?

A: Substitution requires matching inductance value (22.8 µH ±20%), current rating (4.9 A minimum), DC resistance (36mOhm), toroidal type, surface mount capability, and regulatory compliance. Physical dimensions and shielding configuration may differ without affecting electrical substitutability.
