Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 171275-1 is determined by the following critical parameters:

Functional Compatibility Parameters:

• Socket contact type (Pin or Socket designation)
• Crimp termination method
• Gold contact finish material
• Wire gauge range compatibility

Compliance and Regulatory Parameters:

• RoHS compliance status
• Moisture Sensitivity Level (MSL) rating
• ECCN classification
• HTSUS commodity code

The substitute part 76347-312LF from Amphenol ICC (FCI) maintains functional equivalence through matching socket contact configuration, crimp termination, and gold finish specifications. Both parts operate within the same regulatory framework (EAR99 ECCN, 8536.90.4000 HTSUS code) and share identical MSL ratings. The wire gauge specification of the substitute (20-22 AWG) represents a subset of the original part's range (20-24 AWG), establishing compatibility for applications within the overlapping gauge specification.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring 20-22 AWG wire gauges: The Amphenol ICC 76347-312LF (part number 76347-312LF) serves as a direct functional substitute for the obsolete TE Connectivity 171275-1. Both components maintain identical socket contact configuration, crimp termination methodology, and gold plating specifications. The substitute part carries active production status, ensuring availability and supply chain continuity. RoHS3 compliance and MSL 1 ratings are maintained across both components, supporting deployment in regulated environments.

For applications requiring 23-24 AWG wire gauges: The Amphenol ICC 76347-312LF does not accommodate wire gauges above 22 AWG. Alternative solutions must be evaluated for applications requiring the full 20-24 AWG range of the original component.

Regulatory and compliance considerations: Both the original and substitute parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, supporting seamless integration into existing procurement and export compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 76347-312LF replace the TE Connectivity 171275-1 in all applications?

A: The Amphenol ICC 76347-312LF is functionally equivalent for applications utilizing wire gauges within the 20-22 AWG range. Applications requiring 23-24 AWG wire accommodation require evaluation of alternative components, as the substitute part specification does not extend to these gauges.

Q: What is the difference in contact finish thickness between the two parts?

A: The TE Connectivity 171275-1 specifies flash gold plating thickness, while the Amphenol ICC 76347-312LF specifies 30.0µin (0.76µm) thickness. Both finishes provide gold contact material; the thickness specification difference reflects manufacturing process variations between manufacturers.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 171275-1 is ROHS3 Compliant, and the Amphenol ICC 76347-312LF is RoHS Compliant. Both components meet RoHS regulatory requirements.

Q: What is the packaging format of the substitute part?

A: The Amphenol ICC 76347-312LF is supplied in Cut Tape (CT) packaging format.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both the TE Connectivity 171275-1 and Amphenol ICC 76347-312LF carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the current availability status of each part?

A: The TE Connectivity 171275-1 is classified as obsolete but maintains 1030 pieces in current inventory. The Amphenol ICC 76347-312LF is in active production status with 18680 pieces in current inventory, supporting ongoing procurement requirements.
