PE-54036S Equivalent & Substitute Parts

Part Overview

The PE-54036S is a 168 µH shielded toroidal inductor manufactured by Pulse Electronics, rated for 1.81 A with 180mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across the temperature range of -40°C to 130°C and is designed for surface mount applications in nonstandard packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PE-54036S is determined by strict equivalence across the following critical parameters:

• Inductance Value: 168 µH (±20% tolerance)
• Current Rating: 1.81 A minimum
• DC Resistance: 180mOhm
• Mounting Type: Surface Mount
• Package Dimensions: Nonstandard, with maximum seated height of 0.400" (10.16mm)
• Operating Temperature Range: Minimum -40°C to 130°C coverage
• Toroidal Type: Core geometry must be toroidal

Two substitute parts meet these electrical and mechanical criteria:

1. PE-54036SNL (Pulse Electronics) – Direct manufacturer equivalent with identical electrical specifications and active product status
2. SH150S-1.81-168 (Amgis, LLC) – Functionally equivalent with minor dimensional and shielding variations

Parameter Comparison

Engineering Selection Recommendations

PE-54036SNL is the primary substitute for PE-54036S. Both parts are manufactured by Pulse Electronics with identical electrical specifications, mechanical dimensions, and operating temperature range. PE-54036SNL carries active product status and ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete PE-54036S.

SH150S-1.81-168 serves as a secondary substitute when PE-54036SNL is unavailable. This Amgis part maintains electrical equivalence across inductance, current rating, and DC resistance. Key differences include unshielded construction (versus shielded), slightly larger dimensions (0.957" L x 0.925" W, 0.427" height), reduced upper operating temperature limit (125°C versus 130°C), and MSL 2 moisture sensitivity. These differences require circuit-level evaluation for electromagnetic interference considerations and thermal margin verification.

Selection between PE-54036SNL and SH150S-1.81-168 depends on shielding requirements, available board space, and operating temperature margins in the target application.

Frequently Asked Questions (FAQ)

Q: Can PE-54036SNL directly replace PE-54036S without circuit modification?

A: Yes. PE-54036SNL is electrically and mechanically identical to PE-54036S. Both share the same inductance (168 µH), current rating (1.81 A), DC resistance (180mOhm), dimensions, and operating temperature range (-40°C to 130°C). The primary difference is product status and RoHS compliance.

Q: What are the key differences between PE-54036SNL and SH150S-1.81-168?

A: Both maintain 168 µH inductance, 1.81 A current rating, and 180mOhm DC resistance. SH150S-1.81-168 differs in three areas: (1) unshielded versus shielded construction, (2) slightly larger dimensions (0.957" L x 0.925" W x 0.427" height versus 0.940" L x 0.940" W x 0.400" height), and (3) reduced upper operating temperature (125°C versus 130°C) and higher moisture sensitivity (MSL 2 versus MSL 1).

Q: Is SH150S-1.81-168 suitable for applications requiring shielded inductors?

A: No. SH150S-1.81-168 is unshielded, making it unsuitable for applications where electromagnetic shielding is a design requirement. Use PE-54036SNL for shielded applications.

Q: What is the impact of the 5°C temperature difference between PE-54036SNL and SH150S-1.81-168?

A: PE-54036SNL operates to 130°C while SH150S-1.81-168 operates to 125°C. Applications with operating temperatures above 125°C require PE-54036SNL. For applications with maximum operating temperatures at or below 125°C, both parts are acceptable.

Q: Does the MSL 2 rating of SH150S-1.81-168 affect component handling?

A: Yes. MSL 2 requires moisture bake-out procedures and limits shelf life to one year from manufacturing date. MSL 1 (PE-54036SNL) has unlimited shelf life. Procurement and storage procedures must account for this difference when using SH150S-1.81-168.

Q: Are there packaging differences between the substitute parts?

A: Yes. PE-54036SNL is supplied in Bulk packaging, while SH150S-1.81-168 is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly equipment compatibility.
