Würth Elektronik 7473522 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 7473522 is a circuit-board blade fuse clip designed for through-hole mounting applications. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and new design implementations. The fuse clip accommodates ATC and ATO blade fuse types in a vertical orientation with PC pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Würth Elektronik 7473522 is determined by the following critical parameters:

• Mounting Type: Through Hole (mechanical fit requirement)
• Fuse Type: Blade (connector interface standard)
• Fuseholder Type: Clip (mechanical retention method)
• Number of Circuits: 1 (electrical configuration)
• Orientation: Vertical (PCB layout constraint)
• Termination Style: PC Pin (soldering interface)
• Contact Material & Finish: Brass with Tin (electrical conductivity and corrosion resistance)

The Littelfuse Inc. 01000057Z meets all these core parameters. While the substitute part includes additional electrical ratings (15 A at 125V), these represent enhanced specifications that do not prevent functional substitution in applications originally designed for the Würth Elektronik component.

Engineering Selection Recommendations

The Littelfuse Inc. 01000057Z (Series 100_57) is the designated substitute for the obsolete Würth Elektronik 7473522. Selection is based on:

• Mechanical Compatibility: Identical mounting type, orientation, and termination style ensure direct PCB integration without layout modifications.
• Electrical Interface: Matching fuse type (blade), fuseholder type (clip), and circuit configuration (1 circuit) guarantee functional equivalence.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.
• Product Availability: The Littelfuse substitute maintains active product status with substantial inventory availability, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 01000057Z directly replace the Würth Elektronik 7473522 on existing PCBs?

A: Yes. Both components share identical mounting type (through hole), orientation (vertical), termination style (PC pin), and mechanical form factor. No PCB redesign is required.

Q: What is the significance of the current rating difference (15 A at 125V) in the substitute part?

A: The Littelfuse substitute includes explicit electrical ratings. These represent the component's maximum operational capacity and do not restrict its use in applications with lower current or voltage requirements. The substitute is suitable for any application originally designed for the Würth Elektronik component.

Q: Are there packaging differences between these components?

A: The Würth Elektronik 7473522 packaging specification is not provided in the technical data. The Littelfuse 01000057Z is supplied in bulk packaging. Verify packaging requirements for your specific procurement process.

Q: Do both components support ATC and ATO blade fuse types?

A: Yes. Both the Würth Elektronik 7473522 and Littelfuse 01000057Z are designed for use with ATC and ATO blade fuse types.

Q: Are there compliance or certification differences?

A: No. Both components maintain ROHS3 compliance and REACH unaffected status, meeting identical regulatory requirements.
