Key Parameters

Substitute Part Grouping Explanation

Substitution of the 171276-2 is determined by the following critical parameters:

Primary Substitution Criteria:

• Socket contact type (Pin or Socket designation)
• Crimp termination method
• Wire gauge compatibility (20-24 AWG range)
• Rectangular connector category
• RoHS compliance status
• MSL rating of 1 (Unlimited)

The substitute part 76347-312LF meets the functional requirements for socket contact crimp termination. While the substitute operates within a narrower wire gauge range (20-22 AWG versus 20-24 AWG), this represents a compatible subset of the original specification. The substitute employs gold contact finish rather than tin; however, both finishes are acceptable for rectangular connector socket applications within the specified wire gauge parameters.

Parameter Comparison

Engineering Selection Recommendations

The 76347-312LF serves as an active substitute for the obsolete 171276-2. Selection of this substitute is supported by the following factors:

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings, ensuring regulatory and environmental compatibility within existing systems.

Functional Equivalence: Both components provide socket contact crimp termination for rectangular connectors. The wire gauge specification of 76347-312LF (20-22 AWG) encompasses the lower range of the original part (20-24 AWG), providing functional coverage for applications utilizing 20-22 AWG wire.

Product Status: The 76347-312LF is classified as Active, ensuring ongoing availability and supply chain continuity compared to the Obsolete status of 171276-2.

Contact Finish Consideration: The gold finish of 76347-312LF differs from the tin finish of 171276-2. Gold contact finishes provide enhanced corrosion resistance and are suitable for rectangular connector socket applications. This substitution is appropriate for applications where contact reliability and environmental durability are required.

Frequently Asked Questions (FAQ)

Q: Can the 76347-312LF directly replace the 171276-2 in all applications?

A: The 76347-312LF is functionally equivalent for applications utilizing wire gauges within the 20-22 AWG range. Applications requiring 23-24 AWG wire termination require evaluation of alternative substitutes or the original part specification.

Q: What is the significance of the contact finish difference between tin and gold?

A: Both tin and gold are acceptable contact finishes for rectangular connector sockets. Gold provides superior corrosion resistance and is suitable for applications with extended environmental exposure or high-reliability requirements. Tin is suitable for standard industrial applications. The choice depends on application-specific environmental and reliability criteria.

Q: Are there packaging differences between the main part and substitute?

A: The 171276-2 packaging is not specified in the available data. The 76347-312LF is supplied in Cut Tape (CT) packaging. Packaging format should be confirmed based on procurement and assembly requirements.

Q: Do both parts comply with current regulatory standards?

A: Yes. The 171276-2 is ROHS3 Compliant, and the 76347-312LF is RoHS Compliant. Both parts carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory alignment.

Q: What is the MSL rating and why is it important?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.

Q: How does the wire gauge subset affect substitution decisions?

A: The 76347-312LF supports 20-22 AWG wire termination, which is a subset of the original 20-24 AWG specification. For applications using 20-22 AWG wire, the substitute is fully compatible. Applications requiring 23-24 AWG termination require alternative component evaluation.
