Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76342-403 is based on maintaining electrical and mechanical compatibility through identical or equivalent parameters:

Critical Parameters for Substitution:

• Connector type (Receptacle)
• Number of positions (6)
• Pitch and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Insulation material and flammability rating (UL94 V-0)
• Series designation (Dubox™)

The substitute part 76342-403LF maintains all critical mechanical and electrical parameters. The primary difference is the contact finish specification: the substitute uses tin finish instead of tin-lead finish, and carries active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 76342-403LF serves as the direct substitute for the obsolete 76342-403. Both connectors maintain identical mechanical dimensions, pitch specifications, and mounting characteristics. The 76342-403LF is the recommended selection for new designs and replacement applications due to its active product status and RoHS compliance. The contact finish change from tin-lead to tin reflects current manufacturing standards and regulatory requirements. Both parts carry equivalent flammability ratings and insulation specifications suitable for automotive, industrial, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can 76342-403LF be used as a direct replacement for 76342-403? A: Yes.
