TE Connectivity 640108-1 WTB Terminal Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640108-1 is a WTB Tin-Lead Terminal Connector designed for wire gauges 22-26 AWG applications. This through-board, locking terminal connector features phosphor bronze contact material with tin-lead finish and is part of the Mini Amp-In series. The 640108-1 is classified as obsolete, making identification of equivalent substitute parts essential for ongoing procurement and system maintenance. Substitute parts maintain identical electrical and mechanical specifications while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 640108-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 3-640108-1 maintains identical specifications for wire gauge (22-26 AWG), hole diameter (0.055" / 1.40mm), insulation diameter range (0.060" ~ 0.100" / 1.52mm ~ 2.54mm), overall length (0.250" / 6.35mm), terminal type (through board, locking), contact material (phosphor bronze), and series designation (Mini Amp-In).

The primary distinction between the main part and substitute is the contact finish specification and product status. The 640108-1 features tin-lead finish and is obsolete, while the 3-640108-1 features tin finish and maintains active product status. Both parts are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level), ensuring compatibility in regulated applications.

Parameter Comparison

Engineering Selection Recommendations

The 3-640108-1 serves as the direct substitute for the obsolete 640108-1 based on complete electrical and mechanical parameter equivalence. Both parts are manufactured by TE Connectivity AMP Connectors and maintain ROHS3 compliance with MSL rating of 1, ensuring suitability for regulated and moisture-sensitive applications.

The transition from tin-lead to tin contact finish in the 3-640108-1 aligns with industry-wide RoHS compliance initiatives and does not compromise functional compatibility. The active product status of the 3-640108-1 provides superior long-term availability and supply chain reliability compared to the obsolete 640108-1.

The 3-640108-1 is supplied in Cut Tape (CT) packaging, which is standard for high-volume production environments and automated assembly processes. Selection of the 3-640108-1 is appropriate for new designs, redesigns, and ongoing production of systems previously specified with the 640108-1.

Frequently Asked Questions (FAQ)

Q: Can the 3-640108-1 be used as a direct replacement for the 640108-1 in existing designs?

A: Yes. The 3-640108-1 maintains identical electrical and mechanical specifications across all critical parameters including wire gauge, hole diameter, insulation diameter, overall length, terminal type, contact material, and series designation. The parts are functionally interchangeable.

Q: What is the difference between the tin-lead finish of the 640108-1 and the tin finish of the 3-640108-1?

A: The 640108-1 features a tin-lead contact finish, while the 3-640108-1 features a tin-only finish. Both finishes provide equivalent electrical conductivity and contact reliability. The tin finish of the 3-640108-1 reflects current RoHS3 compliance standards and does not affect functional performance in 22-26 AWG applications.

Q: Why is the 640108-1 listed as obsolete?

A: The 640108-1 has been superseded by the 3-640108-1 as part of TE Connectivity's product line evolution and RoHS compliance transition. The 3-640108-1 maintains all functional specifications while offering improved availability and active product status.

Q: What packaging format is the 3-640108-1 supplied in?

A: The 3-640108-1 is supplied in Cut Tape (CT) packaging, which is standard for automated assembly and high-volume production environments. This packaging format is compatible with standard component placement equipment.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 640108-1 and 3-640108-1 are ROHS3 compliant with MSL rating of 1 (unlimited), making them suitable for regulated applications and environments with varying moisture conditions.

Q: What wire gauges are supported by these terminal connectors?

A: Both the 640108-1 and 3-640108-1 support wire gauges from 22 AWG to 26 AWG, with a hole diameter of 0.055" (1.40mm) and insulation diameter range of 0.060" to 0.100" (1.52mm to 2.54mm).
