Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76347-311 is determined by strict equivalence across the following critical parameters:

• Socket contact type (Pin or Socket designation)
• Crimp termination method (Contact Termination)
• Wire gauge range of 20-22 AWG
• Gold contact finish with 30.0µin (0.76µm) thickness specification
• Identical base product number (76347)
• Same series classification (DUBOX™, MezzSelect™, Basics+)
• Moisture Sensitivity Level 1 rating

The substitute part 76347-311LF maintains full electrical and mechanical compatibility with the original 76347-311 specification while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations
