PE-52645 Equivalent & Substitute Parts

Part Overview

The PE-52645 is a 150 µH unshielded toroidal inductor rated for 1.7 A with a maximum DC resistance of 420mOhm, designed for through-hole mounting in radial, vertical corner terminal configuration. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The PE-52645NL represents the active production equivalent with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PE-52645 is determined by strict equivalence across the following critical parameters:

• Inductance value: 150 µH with ±20% tolerance
• Current rating: 1.7 A minimum
• DC resistance: 420mOhm maximum
• Shielding configuration: Unshielded
• Inductor type: Toroidal
• Mounting method: Through hole
• Terminal configuration: Radial, vertical corner terminals
• Physical dimensions: 0.710" L x 0.510" W (18.03mm x 12.95mm)
• Operating temperature range: -40°C ~ 130°C
• Test frequency: 20 kHz

The PE-52645NL meets all these criteria and is classified as a direct substitute. Packaging differences (tube vs. bulk) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PE-52645NL is the direct substitute for the obsolete PE-52645. Both components share identical electrical specifications and mechanical dimensions, ensuring pin-for-pin and form-factor compatibility.

Selection between these parts is determined by product status and regulatory compliance requirements:

• For new designs and ongoing production requiring regulatory compliance, the PE-52645NL is the appropriate choice. It maintains ROHS3 compliance and is actively manufactured.
• The PE-52645 is obsolete and should be replaced in active designs. Existing inventory of PE-52645 may be used for legacy system maintenance only.
• Packaging format (tube for PE-52645NL versus bulk for PE-52645) affects handling and storage but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can PE-52645NL be used as a direct replacement for PE-52645?

A: Yes. The PE-52645NL is electrically and mechanically identical to the PE-52645. All critical parameters—inductance, current rating, DC resistance, dimensions, and terminal configuration—are equivalent. The components are interchangeable in circuit applications.

Q: What is the difference between PE-52645 and PE-52645NL?

A: The primary differences are product status and regulatory compliance. PE-52645 is obsolete and RoHS non-compliant. PE-52645NL is actively manufactured and ROHS3 compliant. Packaging differs (bulk versus tube), but electrical and mechanical specifications are identical.

Q: Does packaging format affect component performance?

A: No. Packaging format (tube or bulk) is a logistics and handling consideration only. It does not affect electrical characteristics, mechanical fit, or performance in circuit applications.

Q: What are the critical parameters for substitution?

A: Substitution requires equivalence in inductance (150 µH ±20%), current rating (1.7 A), DC resistance (420mOhm max), shielding (unshielded), type (toroidal), mounting method (through hole), terminal configuration (radial, vertical corner), physical dimensions (0.710" L x 0.510" W), and operating temperature range (-40°C ~ 130°C).

Q: Is PE-52645NL suitable for new product designs?

A: Yes. PE-52645NL is the active production part and meets current regulatory requirements including ROHS3 compliance. It is the recommended choice for all new designs.
