PE-53120 Equivalent & Substitute Parts

Part Overview

The PE-53120 is a 1 mH unshielded toroidal inductor rated for 950 mA with a maximum DC resistance of 240 mOhm, designed for through-hole mounting in radial, vertical orientation. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The electrical and mechanical specifications remain consistent across qualified alternatives, enabling direct replacement in circuit designs where the original component is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-53120 is determined by strict equivalence across the following critical parameters:

• Inductance value: 1 mH with ±20% tolerance
• Current rating: 950 mA minimum
• DC resistance: 240 mOhm maximum
• Toroidal type with unshielded construction
• Through-hole mounting in radial, vertical orientation
• Physical dimensions compatible with PCB layout constraints
• Operating temperature range support

Two qualified substitutes meet these criteria: PE-53120NL (direct manufacturer equivalent from Pulse Electronics) and SH50C-0.95-1000 (functionally equivalent from Amgis, LLC). Both maintain identical electrical specifications and mechanical form factors within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

PE-53120NL is the primary substitute for PE-53120. Both components are manufactured by Pulse Electronics with identical electrical and mechanical specifications. PE-53120NL carries active product status and ROHS3 compliance, addressing regulatory requirements where the original obsolete part cannot be sourced.

SH50C-0.95-1000 from Amgis, LLC is a functionally equivalent alternative. It maintains all critical electrical parameters and physical form factor compatibility. The operating temperature range extends to -40°C ~ 125°C, which covers the majority of applications within the PE-53120 specification window. Dimensional variations are minimal and within acceptable PCB layout tolerances. SH50C-0.95-1000 also carries ROHS3 compliance and active product status.

Selection between PE-53120NL and SH50C-0.95-1000 depends on supply chain availability, packaging requirements (tube versus tray), and manufacturer preference. Both are qualified substitutes for direct replacement.

Frequently Asked Questions (FAQ)

Q: Can PE-53120NL be used as a direct replacement for PE-53120?

A: Yes. PE-53120NL is manufactured by the same supplier (Pulse Electronics) with identical inductance, current rating, DC resistance, and physical dimensions. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What are the dimensional differences between PE-53120 and SH50C-0.95-1000?

A: PE-53120 measures 1.300" L x 0.700" W x 1.400" H (33.02mm x 17.78mm x 35.56mm). SH50C-0.95-1000 measures 1.252" L x 0.701" W x 1.382" H (31.80mm x 17.81mm x 35.10mm). Variations are less than 2% and do not affect through-hole mounting compatibility in standard PCB layouts.

Q: Does the operating temperature difference between PE-53120NL (-40°C ~ 130°C) and SH50C-0.95-1000 (-40°C ~ 125°C) affect substitution?

A: For applications operating within -40°C ~ 125°C, both parts are equivalent. Applications requiring operation above 125°C must use PE-53120NL or PE-53120.

Q: Are packaging differences between PE-53120NL (tube) and SH50C-0.95-1000 (tray) significant?

A: Packaging affects handling, storage, and supply chain logistics but does not impact electrical or mechanical performance. Selection depends on assembly process requirements and inventory management practices.

Q: What is the core material difference between PE-53120NL and SH50C-0.95-1000?

A: PE-53120NL core material is not specified in available documentation. SH50C-0.95-1000 uses iron powder core material. Both achieve identical inductance and DC resistance specifications, confirming functional equivalence.

Q: Are both substitutes RoHS compliant?

A: PE-53120NL and SH50C-0.95-1000 are both ROHS3 compliant. The original PE-53120 is RoHS non-compliant, making substitution necessary for applications requiring regulatory compliance.
