PE-53112 Equivalent & Substitute Parts

Part Overview

The PE-53112 is a 47 µH unshielded toroidal inductor rated for 3 A continuous current with a maximum DC resistance of 50 mOhm. This through-hole component is manufactured by Pulse Electronics and is currently classified as obsolete. Due to its discontinued status, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-53112 is determined by strict equivalence across the following critical parameters:

• Inductance value: 47 µH
• Inductance tolerance: ±20%
• Current rating: 3 A minimum
• DC resistance: 50 mOhm maximum
• Type: Toroidal
• Shielding: Unshielded
• Mounting type: Through hole
• Operating temperature range: Minimum -40°C to +130°C

Parts are classified into two categories:

Direct Equivalent (PE-53112NL): Identical electrical and mechanical specifications with matching package orientation (Radial, Vertical). This part maintains full form-factor compatibility.

Functional Equivalent (SWC-3.0-47, SWT-3.0-47): Meet all electrical specifications and core mechanical requirements. SWC-3.0-47 maintains vertical orientation compatibility. SWT-3.0-47 uses horizontal orientation, requiring PCB layout adjustment.

Parameter Comparison

Engineering Selection Recommendations

PE-53112NL is the primary substitute for PE-53112. Both parts are manufactured by Pulse Electronics with identical electrical specifications and package orientation. PE-53112NL is currently in active production status with ROHS3 compliance, making it the direct replacement for obsolete stock management and new designs.

SWC-3.0-47 (Amgis, LLC) provides functional equivalence with all critical electrical parameters matched. The part maintains vertical package orientation compatible with existing PCB layouts. Operating temperature range is reduced to -40°C ~ 125°C, which remains within typical industrial specifications. ROHS3 compliance is confirmed.

SWT-3.0-47 (Amgis, LLC) meets all electrical requirements but uses horizontal package orientation. This configuration requires PCB layout modification and is suitable only when vertical space constraints necessitate horizontal mounting. Operating temperature range is -40°C ~ 125°C with ROHS3 compliance.

Selection should prioritize PE-53112NL for direct replacement applications. SWC-3.0-47 serves as a secondary option when PE-53112NL availability is constrained. SWT-3.0-47 is applicable only when horizontal orientation is required by design constraints.

Frequently Asked Questions (FAQ)

Q: Can PE-53112NL be used as a direct replacement for PE-53112?

A: Yes. PE-53112NL is electrically and mechanically identical to PE-53112, with matching inductance (47 µH), current rating (3 A), DC resistance (50 mOhm max), and package orientation (Radial, Vertical). The primary difference is product status: PE-53112NL is active production while PE-53112 is obsolete.

Q: What is the difference between SWC-3.0-47 and SWT-3.0-47?

A: Both parts are manufactured by Amgis, LLC with identical electrical specifications. The key difference is package orientation: SWC-3.0-47 uses Radial, Vertical (Open) orientation matching the original PE-53112 footprint, while SWT-3.0-47 uses Radial, Horizontal (Open) orientation. Horizontal orientation requires PCB layout modification.

Q: Are there temperature range differences between substitute parts?

A: PE-53112 and PE-53112NL both support -40°C ~ 130°C. SWC-3.0-47 and SWT-3.0-47 support -40°C ~ 125°C. The 5°C reduction in maximum operating temperature is within typical industrial tolerance margins for most applications.

Q: Do all substitute parts meet RoHS compliance?

A: PE-53112 is RoHS non-compliant. PE-53112NL, SWC-3.0-47, and SWT-3.0-47 are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What packaging formats are available?

A: PE-53112NL is supplied in Tube packaging. SWC-3.0-47 and SWT-3.0-47 are supplied in Bulk packaging. Packaging format selection depends on production volume and inventory management requirements.

Q: Can SWC-3.0-47 be used interchangeably with PE-53112 on existing PCBs?

A: Yes, for vertical mounting applications. SWC-3.0-47 maintains the same Radial, Vertical (Open) package orientation as PE-53112, ensuring PCB footprint compatibility without layout modification.
