TE Connectivity 640931-2 Quick Connect Female Crimp Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640931-2 is a 0.110" (2.79mm) Quick Connect Female Crimp Connector designed for 14-16 AWG wire applications. This terminal features non-mating end insulation and is part of the Faston and PIDG series connector families. The component is classified as an Active product with full RoHS3 compliance and MSL 1 rating. Substitute parts are identified when packaging configurations differ while maintaining identical electrical and mechanical specifications, or when inventory availability requires alternative sourcing from the same manufacturer and series.

Substitute Part Grouping Explanation

Substitution between TE Connectivity 640931-2 and 640931-1 is valid based on identical electrical and mechanical parameters. Both parts share the following critical specifications that determine functional interchangeability:

Tab width: 0.110" (2.79mm)
Tab thickness: 0.032" (0.81mm)
Tab length: 0.250" (6.35mm)
Wire gauge compatibility: 14-16 AWG
Termination method: Crimp
Insulation configuration: Non-Mating End Insulated
Contact material and finish: Brass with Tin plating
Series classification: Faston and PIDG
Product status: Active
Compliance certifications: ROHS3 Compliant, MSL 1

The primary distinction between these parts is packaging format. The 640931-2 is supplied in Cut Tape (CT) packaging, while the 640931-1 is supplied in Bulk packaging. This difference does not affect the terminal's electrical or mechanical performance in the application.

Engineering Selection Recommendations

Both the 640931-2 and 640931-1 are Active products manufactured by TE Connectivity with full ROHS3 compliance and MSL 1 certification. Selection between these parts should be based on packaging requirements and inventory availability rather than electrical or mechanical performance considerations.

The 640931-2 in Cut Tape packaging is suitable for applications requiring controlled dispensing and organized component handling. The 640931-1 in Bulk packaging is appropriate for high-volume assembly operations where loose component feeding is acceptable.

Both parts maintain identical contact geometry, wire gauge compatibility, and termination specifications. No performance degradation or compatibility issues result from substituting one part for the other in the application circuit.

Frequently Asked Questions (FAQ)

Q: Are the 640931-2 and 640931-1 electrically identical?

A: Yes. Both parts feature identical tab width (0.110"), tab thickness (0.032"), tab length (0.250"), wire gauge rating (14-16 AWG), contact material (Brass with Tin finish), and insulation configuration. Electrical performance is equivalent.

Q: What is the only difference between these two parts?

A: The packaging format. The 640931-2 is supplied in Cut Tape (CT) configuration, while the 640931-1 is supplied in Bulk packaging. The terminal itself is identical.

Q: Can I use 640931-1 in place of 640931-2 in my assembly process?

A: Substitution is valid from an electrical and mechanical standpoint. However, assembly process compatibility depends on your equipment's ability to handle Bulk packaging versus Cut Tape packaging. Verify your component feeding system supports the packaging format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 640931-2 and 640931-1 are ROHS3 compliant with MSL 1 rating and Active product status.

Q: What wire gauges are compatible with these connectors?

A: Both parts are rated for 14-16 AWG wire. Do not use with wire gauges outside this range.

Q: Are these parts suitable for high-volume production?

A: Yes. The 640931-1 Bulk packaging option provides 12,583 pieces in stock, making it suitable for high-volume applications. The 640931-2 Cut Tape option provides 1,458 pieces and is suitable for controlled dispensing applications.

Q: What is the crimp termination method for these connectors?

A: Both parts use standard crimp termination. Ensure your crimping tool is rated for 14-16 AWG wire and 0.110" tab width connectors.
