PE-54044S Equivalent & Substitute Parts

Part Overview

The PE-54044S is a 77 µH shielded toroidal inductor manufactured by Pulse Electronics, rated for 3 A continuous current with 80 mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across the industrial temperature range of -40°C to 130°C and is housed in a nonstandard surface mount package measuring 23.88mm × 23.88mm × 10.16mm (max height).

Substitute Part Grouping Explanation

Substitution for the PE-54044S is determined by strict equivalence across the following critical parameters: inductance value (77 µH), inductance tolerance (±20%), current rating (3 A), DC resistance (80 mOhm), mounting type (surface mount), and package footprint compatibility (23.88mm × 23.88mm nonstandard case).

Two substitute categories exist:

Direct Equivalent (Shielded): PE-54044SNL maintains identical electrical specifications and shielding characteristics as the main part, differing only in packaging format (bulk vs. tape & reel) and product status (active vs. obsolete).

Functional Equivalents (Unshielded): SH150S-3.00-77 and SWS-3.00-77 provide identical inductance, current rating, and DC resistance but differ in shielding configuration (unshielded vs. shielded), core material (iron powder), operating temperature ceiling (125°C vs. 130°C), and physical dimensions. These parts are suitable only where electromagnetic shielding is not a design requirement.

Parameter Comparison

Engineering Selection Recommendations

PE-54044SNL is the primary substitute for PE-54044S. It provides complete electrical and mechanical equivalence with identical shielding, temperature range, and footprint. The part is active in production status and ROHS3 compliant, addressing regulatory requirements that the obsolete main part does not meet. Packaging differs (bulk vs. tape & reel), which may affect procurement workflows but does not impact functional performance.

SH150S-3.00-77 and SWS-3.00-77 are functional alternatives only in applications where electromagnetic shielding is not required. Both parts maintain the critical electrical parameters (77 µH, 3 A, 80 mOhm) but operate at a reduced maximum temperature (125°C vs. 130°C). Physical dimensions vary slightly, requiring verification of PCB layout compatibility. Both are ROHS3 compliant and actively produced.

Selection between SH150S-3.00-77 and SWS-3.00-77 depends on specific footprint constraints: SH150S-3.00-77 measures 24.30mm × 24.60mm × 10.85mm, while SWS-3.00-77 measures 24.60mm × 24.60mm × 12.85mm. The SWS variant offers improved dimensional compatibility with the original 23.88mm × 23.88mm footprint in the horizontal plane but exceeds the original height specification.

Frequently Asked Questions (FAQ)

Q: Can PE-54044SNL be used as a direct replacement for PE-54044S?

A: Yes. PE-54044SNL is electrically and mechanically equivalent to PE-54044S across all critical parameters: 77 µH inductance, 3 A current rating, 80 mOhm DC resistance, shielded configuration, and operating temperature range (-40°C to 130°C). The only differences are product status (active vs. obsolete) and packaging format (bulk vs. tape & reel).

Q: What is the primary difference between PE-54044SNL and the Amgis alternatives?

A: PE-54044SNL maintains the shielded toroidal design of the original part. SH150S-3.00-77 and SWS-3.00-77 are unshielded toroidal inductors. Shielding reduces electromagnetic interference coupling to surrounding circuits. Use shielded variants (PE-54044SNL) in noise-sensitive applications; unshielded variants (Amgis parts) are acceptable where EMI is not a design constraint.

Q: Are there physical footprint differences between these parts?

A: Yes. PE-54044S and PE-54044SNL both measure 23.88mm × 23.88mm × 10.16mm (max height). SH150S-3.00-77 measures 24.30mm × 24.60mm × 10.85mm. SWS-3.00-77 measures 24.60mm × 24.60mm × 12.85mm. Verify PCB layout clearances before substitution, particularly for height-constrained applications.

Q: Do the Amgis parts meet the same temperature specifications?

A: No. PE-54044S and PE-54044SNL operate from -40°C to 130°C. SH150S-3.00-77 and SWS-3.00-77 operate from -40°C to 125°C. Applications requiring operation above 125°C must use PE-54044SNL.

Q: Are all substitute parts RoHS compliant?

A: PE-54044S is RoHS non-compliant. PE-54044SNL, SH150S-3.00-77, and SWS-3.00-77 are all ROHS3 compliant. For designs subject to RoHS regulations, use PE-54044SNL or the Amgis alternatives.

Q: What packaging formats are available?

A: PE-54044S is supplied in tape & reel format. PE-54044SNL is supplied in bulk. SH150S-3.00-77 and SWS-3.00-77 are supplied in tape & reel format. Confirm packaging requirements with procurement before ordering.
