PE-54039S Equivalent & Substitute Parts

Part Overview

The PE-54039S is a 53 µH shielded toroidal inductor manufactured by Pulse Electronics, rated for 3 A continuous current with 80mOhm 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).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-54039S is determined by the following critical parameters: inductance value (53 µH ±20%), current rating (3 A minimum), DC resistance (80mOhm), mounting type (surface mount), and physical dimensions compatible with the nonstandard package footprint. Shielding characteristics and core material are secondary considerations that may affect electromagnetic performance in specific applications but do not preclude functional substitution when primary electrical parameters are met.

Two substitute parts are identified:

PE-54039SNL (Pulse Electronics): Identical electrical specifications to the main part with active product status and improved RoHS3 compliance. Packaging differs (bulk vs. standard tape & reel).

SH150S-3.00-53 (Amgis, LLC): Meets all primary electrical parameters with minor dimensional variance and unshielded core construction. Active product status with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

PE-54039SNL is the primary substitute for PE-54039S. Both parts are manufactured by Pulse Electronics with identical electrical and mechanical specifications. PE-54039SNL offers the advantage of active product status, ensuring long-term availability and supply chain continuity. RoHS3 compliance of PE-54039SNL addresses regulatory requirements that the obsolete PE-54039S does not meet. Packaging format differs (bulk vs. standard), which may affect procurement workflows but does not impact electrical performance.

SH150S-3.00-53 serves as a secondary substitute when PE-54039SNL is unavailable. This part meets all primary electrical parameters (53 µH, 3 A, 80mOhm) and maintains active product status with RoHS3 compliance. The unshielded core construction represents the primary functional difference; applications requiring electromagnetic shielding should verify compatibility before selection. Dimensional variance (24.30mm × 24.60mm × 10.85mm vs. 23.88mm × 23.88mm × 10.16mm) requires PCB layout verification. Operating temperature maximum is reduced to 125°C, and moisture sensitivity increases to MSL 2, which may affect storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can PE-54039SNL directly replace PE-54039S without design changes?

A: Yes. PE-54039SNL is electrically and mechanically identical to PE-54039S. Both parts share the same inductance (53 µH ±20%), current rating (3 A), DC resistance (80mOhm), shielding characteristics, and physical dimensions. The primary difference is product status (active vs. obsolete) and RoHS compliance level.

Q: What is the key difference between PE-54039SNL and SH150S-3.00-53?

A: The primary difference is shielding: PE-54039SNL is shielded (matching the original PE-54039S), while SH150S-3.00-53 is unshielded. Both maintain identical inductance, current rating, and DC resistance. SH150S-3.00-53 has minor dimensional variance and reduced maximum operating temperature (125°C vs. 130°C).

Q: Does the unshielded design of SH150S-3.00-53 affect performance?

A: Shielding reduces electromagnetic radiation and susceptibility to external fields. Applications sensitive to EMI/RFI should verify that unshielded operation meets performance requirements. Electrical parameters (inductance, current rating, DCR) remain unchanged.

Q: Are there packaging considerations when substituting these parts?

A: PE-54039SNL is supplied in bulk packaging, while SH150S-3.00-53 is supplied in tape & reel format. Procurement and assembly processes may require adjustment. SH150S-3.00-53 has slightly larger dimensions (24.30mm × 24.60mm × 10.85mm); PCB layout must accommodate the increased height (10.85mm vs. 10.16mm).

Q: What compliance differences exist between these parts?

A: PE-54039S is RoHS non-compliant. Both PE-54039SNL and SH150S-3.00-53 are RoHS3 compliant. If regulatory compliance is required, PE-54039S cannot be used in new designs; PE-54039SNL or SH150S-3.00-53 must be selected. Moisture sensitivity differs: PE-54039SNL is MSL 1 (unlimited storage), while SH150S-3.00-53 is MSL 2 (1-year storage limit).

Q: Which substitute should be selected for new designs?

A: PE-54039SNL is the recommended choice for new designs due to identical specifications to the original part and active product status. SH150S-3.00-53 is suitable when PE-54039SNL is unavailable, provided that unshielded operation and dimensional variance are acceptable for the application.
