TE Connectivity 640249-1 Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640249-1 is a ring terminal connector with D-shaped configuration designed for 8-10 AWG wire gauges and #10 stud applications. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The part functions as a crimp-style termination connector for non-insulated ring terminal applications in electrical assemblies requiring secure wire-to-stud connections.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640249-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for terminal type, stud size, wire gauge range, termination method, contact material, contact finish, and all dimensional characteristics including thickness, width, length, and insulation diameter.

The TE Connectivity 640249-3 qualifies as a direct substitute based on complete parameter alignment across these criteria. Both parts share the same base product number (640249), confirming design equivalence. The primary distinction between these parts is product status and packaging configuration, not functional or dimensional characteristics.

Key Parameters Determining Substitution:

• Terminal Type: D-Shaped
• Stud/Tab Size: #10
• Wire Gauge: 8-10 AWG
• Contact Material: Brass with Tin finish
• All dimensional specifications
• Termination method: Crimp
• Insulation configuration: Non-Insulated

Engineering Selection Recommendations

The TE Connectivity 640249-3 serves as the direct functional equivalent to the obsolete 640249-1 model. Both parts are manufactured by TE Connectivity and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 640249-1 is classified as obsolete, while the 640249-3 maintains active product status. For new designs and ongoing procurement, the 640249-3 is the appropriate selection.

Compliance Consideration: The 640249-3 achieves ROHS3 compliance, whereas the 640249-1 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must utilize the 640249-3.

Availability Consideration: The 640249-3 maintains significantly higher inventory levels (18,572 pieces) compared to the 640249-1 (795 pieces), supporting consistent supply chain management.

Packaging Consideration: The 640249-3 is supplied in Cut Tape (CT) packaging, which is standard for component distribution and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 640249-3 be used as a direct replacement for the 640249-1 in existing assemblies?

A: Yes. The 640249-3 is functionally and dimensionally identical to the 640249-1 across all electrical and mechanical parameters. Both parts feature D-shaped terminal configuration, #10 stud size, 8-10 AWG wire gauge capacity, brass contact material with tin finish, and identical dimensional specifications. The parts are interchangeable from a functional standpoint.

Q: What is the primary difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 640249-1 is obsolete and RoHS non-compliant, while the 640249-3 is an active product with ROHS3 compliance. Packaging also differs, with the 640249-3 supplied in Cut Tape format.

Q: Are there any dimensional or electrical differences between 640249-1 and 640249-3?

A: No. Both parts maintain identical specifications for thickness (0.040"), width (0.425"), length (0.962"), insulation diameter (0.190" to 0.230"), wire gauge range (8-10 AWG), contact material (brass with tin finish), and all other electrical and mechanical parameters.

Q: Why should I select the 640249-3 over the 640249-1?

A: The 640249-3 should be selected for new designs and ongoing applications due to active product status, ROHS3 compliance, and superior inventory availability. The 640249-1 is obsolete and presents supply chain risk.

Q: Is the Cut Tape packaging of the 640249-3 compatible with automated assembly equipment?

A: Cut Tape (CT) packaging is standard for automated component placement and assembly processes. This packaging format is compatible with standard tape feeders used in pick-and-place equipment.

Q: What wire gauges are supported by these ring terminals?

A: Both the 640249-1 and 640249-3 support wire gauges from 8 AWG to 10 AWG, with insulation diameter specifications of 0.190" to 0.230" (4.83mm to 5.84mm).

Q: Are these terminals suitable for insulated or non-insulated applications?

A: These terminals are non-insulated ring connectors. They do not include insulation sleeves and are designed for applications where the terminal itself is not insulated.

Q: What is the stud size for these ring terminals?

A: Both parts feature a #10 stud size, which accommodates standard #10 fasteners and studs in electrical assemblies.
