Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640923-2 is determined by electrical and mechanical parameter equivalence. The primary differentiator between the main part and its substitute is packaging format. Both the 640923-2 (Cut Tape packaging) and 640923-1 (Bulk packaging) share identical electrical and mechanical specifications, including tab dimensions, wire gauge compatibility, termination method, contact material and finish, insulation characteristics, and overall physical dimensions.

The substitute relationship is based on the following critical parameters:

Tab Width: 0.110" (2.79mm)
Tab Thickness: 0.020" (0.51mm)
Wire Gauge: 18-22 AWG
Termination: Crimp
Gender: Female
Contact Material: Brass with Tin finish
Insulation: Non-Mating End Insulated

Both parts maintain identical compliance certifications (ROHS3 Compliant, MSL 1) and belong to the same Faston and PIDG series families.

Engineering Selection Recommendations

The TE Connectivity 640923-1 serves as a direct functional equivalent to the 640923-2. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications across all critical parameters. Selection between these parts is determined by packaging requirements and inventory availability rather than technical performance differences.

The 640923-2 in Cut Tape packaging is suitable for applications requiring smaller quantity dispensing and automated pick-and-place assembly processes. The 640923-1 in Bulk packaging accommodates higher-volume production runs and manual assembly operations.

Both parts maintain Active product status and full compliance with ROHS3 standards and MSL 1 (Unlimited) moisture sensitivity ratings. No technical performance degradation occurs when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are the 640923-2 and 640923-1 electrically identical?

A: Yes. Both parts feature identical tab dimensions (0.110" width, 0.020" thickness, 0.250" length), wire gauge compatibility (18-22 AWG), contact material (Brass with Tin finish), and insulation specifications. Electrical performance is equivalent.

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

A: The packaging format. The 640923-2 is supplied in Cut Tape (CT) packaging, while the 640923-1 is supplied in Bulk packaging. All other specifications are identical.

Q: Can I use the 640923-1 in place of the 640923-2 in my assembly?

A: Yes. The 640923-1 is a direct substitute for the 640923-2. The connector specifications, dimensions, and performance characteristics are identical. Packaging differences do not affect functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 640923-2 and 640923-1 are ROHS3 Compliant and carry an MSL rating of 1 (Unlimited).

Q: Which part should I select for high-volume production?

A: The 640923-1 in Bulk packaging is optimized for high-volume applications. The 640923-2 in Cut Tape packaging is suitable for lower-volume or automated assembly processes.

Q: Do these parts require different crimping tools or techniques?

A: No. Both parts use identical crimp termination specifications and are compatible with the same crimping equipment and procedures.

Q: What wire gauges are compatible with these connectors?

A: Both parts accommodate 18-22 AWG wire sizes.
