PE-52629 Equivalent & Substitute Parts

Part Overview

The PE-52629 is a 680 µH unshielded toroidal inductor rated for 850 mA with a maximum DC resistance of 1.5 Ohm, designed for through-hole mounting in radial, horizontal corner terminal configuration. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 130°C and has been tested at 20 kHz inductance frequency.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-52629 is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 680 µH with ±20% tolerance
• Current rating: 850 mA minimum
• DC resistance: 1.5 Ohm maximum
• Inductor type: Toroidal configuration
• Shielding classification: Unshielded
• Mounting method: Through-hole radial with horizontal corner terminals
• Physical footprint: 0.710" L x 0.710" W, 0.460" height maximum
• Operating temperature range: -40°C to 130°C
• Test frequency: 20 kHz

Substitute parts must match all electrical specifications and maintain identical mechanical compatibility to ensure direct replacement without circuit redesign or PCB modification.

Engineering Selection Recommendations

The PE-52629NL is the direct equivalent substitute for the obsolete PE-52629. Both parts are manufactured by Pulse Electronics and share identical electrical and mechanical specifications across all critical parameters: 680 µH inductance, 850 mA current rating, 1.5 Ohm maximum DC resistance, and through-hole radial mounting configuration.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The PE-52629NL carries active product status with ROHS3 compliance, whereas the PE-52629 is classified as obsolete and RoHS non-compliant. For new designs or production continuity, the PE-52629NL is the appropriate selection. Both parts maintain identical operating temperature ranges (-40°C to 130°C) and moisture sensitivity classifications (MSL 1).

Packaging differs between the two variants: PE-52629NL is supplied in tube packaging, while PE-52629 uses standard packaging. This distinction affects handling and inventory management but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can PE-52629NL be used as a direct replacement for PE-52629 in existing designs?

A: Yes. The PE-52629NL is electrically and mechanically identical to the PE-52629 across all specified parameters: inductance value, current rating, DC resistance, physical dimensions, and mounting configuration. Direct substitution is possible without circuit modification or PCB redesign.

Q: What is the significance of the product status difference between these parts?

A: The PE-52629 is classified as obsolete, indicating it is no longer in active production. The PE-52629NL maintains active product status, ensuring continued availability and supply chain support. For new production or long-term designs, the active part is the recommended choice.

Q: How does RoHS compliance affect part selection?

A: The PE-52629NL is ROHS3 compliant, while the PE-52629 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the PE-52629NL must be selected. Both parts are REACH unaffected.

Q: Are the physical dimensions identical between PE-52629 and PE-52629NL?

A: Yes. Both parts measure 0.710" L x 0.710" W (18.03mm x 18.03mm) with a maximum seated height of 0.460" (11.68mm). PCB footprints and mounting hole patterns are identical.

Q: Does packaging type affect electrical performance?

A: No. The PE-52629NL is supplied in tube packaging while PE-52629 uses standard packaging. This distinction affects only handling, storage, and inventory management. Electrical and mechanical specifications remain unchanged.

Q: What is the inductance tolerance for these parts?

A: Both PE-52629 and PE-52629NL carry an inductance tolerance of ±20%, meaning the actual inductance value will fall within the range of 544 µH to 816 µH at the 20 kHz test frequency.

Q: Are there any temperature or environmental limitations for these inductors?

A: Both parts operate across -40°C to 130°C. Moisture sensitivity level is classified as MSL 1 (unlimited), indicating no moisture-related storage or handling restrictions.
