Equivalent & Substitute Parts for Würth Elektronik 7471282

Part Overview

The Würth Elektronik 7471282 is a circuit-board blade terminal classified as a standard male solder connector with non-insulated design. Featuring a 0.110" (2.79mm) quick connect tab, this component is part of the WA-MTAB series and utilizes brass construction with tin plating for reliable electrical contact. The product is currently obsolete, necessitating identification of functionally equivalent alternatives to maintain system compatibility and ensure continued availability for repair, maintenance, and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Würth Elektronik 7471282 is determined by alignment across the following critical parameters:

• Connector Type and Gender: Male configuration for mating with female receptacles
• Tab Dimensions: 0.110" (2.79mm) width, 0.032" (0.81mm) thickness, and 0.280" (7.11mm) length to ensure mechanical fit
• Overall Length: 0.551" (14.00mm) for board-level integration compatibility
• Termination Method: Solder termination for permanent circuit board attachment
• Contact Material and Finish: Brass with tin plating for electrical conductivity and corrosion resistance
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status for regulatory alignment

The substitute part Littelfuse/Commercial Vehicle Products 1282 represents an alternative within the connector ecosystem. However, this part operates as a circular connector receptacle rather than a blade terminal, indicating a different mechanical and electrical interface paradigm. Substitution between these components requires verification of mating interface compatibility and system-level electrical requirements.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 7471282 is classified as obsolete, requiring alternative sourcing for ongoing applications. The Littelfuse 1282 maintains active product status and carries equivalent regulatory certifications (ROHS3 Compliant, REACH Unaffected), supporting long-term supply chain viability.

However, fundamental differences exist between these components:

• The 7471282 functions as a male blade terminal with solder termination, designed for direct circuit board integration
• The Littelfuse 1282 operates as a circular connector receptacle with screw termination, designed for in-line cable connections

These architectural differences necessitate system-level evaluation. Direct mechanical substitution is not feasible without redesign of mating interfaces and termination methodology. Selection should be based on whether the application requires blade terminal functionality (necessitating alternative blade terminal sources) or can accommodate circular connector receptacle architecture with screw termination.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 1282 directly replace the Würth Elektronik 7471282?

A: No. The 7471282 is a male blade terminal with solder termination, while the Littelfuse 1282 is a circular connector receptacle with screw termination. These represent different connector families with incompatible mechanical interfaces.

Q: Why is the 7471282 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates identification of alternative components for repair, maintenance, and new design applications.

Q: What parameters must match for blade terminal substitution?

A: Critical parameters include tab width (0.110"), tab thickness (0.032"), tab length (0.280"), overall length (0.551"), termination method (solder), contact material (brass), and contact finish (tin).

Q: Are both parts regulatory compliant?

A: Yes. Both the Würth Elektronik 7471282 and Littelfuse 1282 are ROHS3 compliant and REACH unaffected, supporting regulatory alignment in applicable markets.

Q: What is the primary difference in termination methodology?

A: The 7471282 uses solder termination for permanent circuit board attachment, while the Littelfuse 1282 uses screw termination for cable connection. These methods are fundamentally different and require distinct assembly processes.

Q: Should I consider the Littelfuse 1282 for my application?

A: Only if your system architecture can accommodate a circular connector receptacle with screw termination instead of a blade terminal with solder termination. Evaluate mating interface requirements and termination methodology compatibility before selection.
