Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640271-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters: Wire gauge range (18-22 AWG), stud size (10 Stud), contact material (Steel), and contact finish (Tin) must be identical to ensure proper electrical connection and current-carrying capacity.

Mechanical Parameters: Terminal type (Circular), insulation diameter (0.080" ~ 0.120"), thickness (0.025"), width (0.370"), and overall length (0.772") must match precisely to ensure physical compatibility with mating components and mounting structures.

Functional Parameters: Termination method (Crimp), insulation type (Non-Insulated), features (Inner Teeth, Serrated Termination), and mounting type (Free Hanging In-Line) must be identical to maintain functional equivalence.

The substitute part 640271-3 satisfies all these criteria while offering the advantage of active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 640271-3 serves as the direct functional equivalent to the obsolete 640271-1 model. Both parts share identical electrical and mechanical specifications, ensuring drop-in compatibility in applications originally designed for the 640271-1.

Product Status Consideration: The 640271-1 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 640271-3 maintains active product status with significantly higher inventory levels (125,185 pieces versus 949 pieces), providing reliable long-term supply chain access.

Regulatory Compliance: The 640271-3 achieves ROHS3 compliance, whereas the 640271-1 is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance documentation, the 640271-3 is the appropriate selection. The REACH status differs between parts, with 640271-3 listed as Vendor Undefined; however, both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Packaging Availability: The 640271-3 is supplied in Cut Tape (CT) packaging, which is standard for high-volume component distribution and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 640271-3 be used as a direct replacement for the 640271-1?

A: Yes. The 640271-3 is electrically and mechanically identical to the 640271-1 across all specified parameters, including wire gauge, stud size, contact material, dimensions, and termination method. No design modifications are required for substitution.

Q: What is the primary reason to transition from 640271-1 to 640271-3?

A: The 640271-1 is obsolete with limited remaining inventory. The 640271-3 is an active product with substantially higher availability, ensuring consistent supply for current and future production requirements.

Q: Are there any compliance differences between these parts?

A: Yes. The 640271-3 is ROHS3 compliant, while the 640271-1 is RoHS non-compliant. For applications requiring RoHS certification or operating in regulated markets, the 640271-3 is the appropriate choice.

Q: Does packaging differ between these parts?

A: Yes. The 640271-3 is supplied in Cut Tape (CT) packaging. The original packaging specification for 640271-1 is not provided in the technical data. Cut Tape packaging is standard for automated assembly and high-volume applications.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts have identical thickness (0.025"), width (0.370"), overall length (0.772"), and insulation diameter range (0.080" ~ 0.120"). Physical compatibility with mating components and mounting structures is maintained.

Q: What wire gauges are supported by the 640271-3?

A: The 640271-3 supports 18-22 AWG wire gauges, identical to the 640271-1. The insulation diameter range of 0.080" ~ 0.120" accommodates this wire gauge specification.

Q: Is the 640271-3 suitable for applications requiring non-insulated terminals?

A: Yes. The 640271-3 is a non-insulated terminal, matching the specification of the 640271-1. Both parts feature inner teeth and serrated termination for secure crimp connections.
