PE-53604 Equivalent & Substitute Parts

Part Overview

The PE-53604 is a 58.1 µH unshielded toroidal inductor rated for 1.3 A with a maximum DC resistance of 290mOhm, manufactured by Pulse Electronics in the SLIC series. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The PE-53604NL serves as the direct functional equivalent with identical electrical and mechanical specifications but maintains active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The PE-53604NL qualifies as a direct substitute based on matching all critical electrical parameters: inductance value of 58.1 µH, current rating of 1.3 A, and DC resistance of 290mOhm maximum. Mechanical compatibility is confirmed through identical package dimensions (0.570" L x 0.565" W, 14.48mm x 14.35mm) and seated height (0.360" / 9.14mm). Both parts share identical operating temperature range (-40°C ~ 130°C) and moisture sensitivity classification (MSL 1). The substitution is valid for applications requiring surface mount toroidal inductors within these specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The PE-53604NL is the appropriate selection for new designs and production transitions. While the PE-53604 remains available in inventory (1096 pcs), its obsolete status and RoHS non-compliance present long-term supply and regulatory risks. The PE-53604NL maintains identical electrical and mechanical performance while offering active product status and ROHS3 compliance, ensuring regulatory alignment and sustained component availability. For applications subject to RoHS requirements, PE-53604NL is mandatory. For legacy systems currently using PE-53604, the substitute provides drop-in compatibility without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can PE-53604NL replace PE-53604 in existing designs? A: Yes. Both parts are electrically and mechanically identical with matching inductance (58.1 µH), current rating (1.3 A), DC resistance (290mOhm max), and package dimensions. Direct substitution is valid without circuit modification.
