PE-51514 Equivalent & Substitute Parts

Part Overview

The PE-51514 is a 32 µH unshielded toroidal inductor rated for 6.6 A continuous current with a maximum DC resistance of 25mOhm. This through-hole component is designed for radial, vertical mounting with 4 open leads. The part is currently obsolete, making identification of compatible substitutes essential for ongoing production support and design continuity. Equivalent parts must maintain identical electrical specifications and mechanical form factors to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the PE-51514 is determined by strict equivalence across the following critical parameters:

• Inductance value: 32 µH (exact match required)
• Current rating: 6.6 A (exact match required)
• DC resistance: 25mOhm maximum (exact match required)
• Inductor type: Toroidal (exact match required)
• Shielding configuration: Unshielded (exact match required)
• Mounting method: Through hole, radial vertical orientation (exact match required)
• Physical dimensions: 1.200" L x 0.600" W, 1.200" height seated (exact match required)
• Lead configuration: 4 leads, open (exact match required)
• Operating temperature range: -40°C ~ 130°C (exact match required)

The PE-51514NL meets all substitution criteria as a direct equivalent part from the same manufacturer, Pulse Electronics, with identical electrical and mechanical specifications.

Engineering Selection Recommendations

The PE-51514NL is the direct equivalent substitute for the obsolete PE-51514. Both parts are manufactured by Pulse Electronics and share identical electrical and mechanical specifications across all critical parameters: 32 µH inductance, 6.6 A current rating, 25mOhm maximum DC resistance, toroidal unshielded construction, through-hole radial vertical mounting, and identical physical dimensions.

The PE-51514NL offers additional advantages for new designs and ongoing production:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance meets current environmental and regulatory requirements
• Tray packaging provides improved handling and inventory management compared to bulk packaging

Both parts operate across the identical temperature range of -40°C to 130°C and are tested at 50 kHz inductance frequency. Direct substitution requires no circuit modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can PE-51514NL be used as a direct replacement for PE-51514 in existing designs?

A: Yes. The PE-51514NL is a direct equivalent with identical inductance (32 µH), current rating (6.6 A), DC resistance (25mOhm max), physical dimensions, and mounting configuration. No circuit or PCB modifications are required.

Q: What is the difference between PE-51514 and PE-51514NL?

A: The parts are electrically and mechanically identical. Differences exist only in product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (bulk vs. tray). The "NL" designation indicates the newer, compliant variant.

Q: Why is the PE-51514 listed as obsolete?

A: The PE-51514 has been superseded by the PE-51514NL, which maintains full electrical and mechanical compatibility while offering improved compliance and supply availability.

Q: Are there any compatibility concerns with PCB mounting?

A: No. Both parts use identical through-hole radial vertical mounting with 4 open leads and the same physical footprint (1.200" L x 0.600" W, 1.200" height seated). PCB layouts designed for PE-51514 accept PE-51514NL without modification.

Q: Does packaging format affect electrical performance?

A: No. Tray packaging (PE-51514NL) and bulk packaging (PE-51514) do not affect component performance. Packaging differences relate only to handling, storage, and inventory management.

Q: What temperature range do these inductors support?

A: Both PE-51514 and PE-51514NL operate across -40°C to 130°C. Inductance is tested at 50 kHz across this full temperature range.
