Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 176381-6 is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug with center strip contacts
• Position Count: 140 positions
• Pitch Specification: 0.050" (1.27mm)
• Row Configuration: 2 rows
• Mounting Configuration: Through hole, right angle orientation
• Contact Finish: Gold plating at 11.8µin (0.30µm) thickness
• Board Height: 0.335" (8.50mm) above board
• Mechanical Features: Board lock functionality
• Series Classification: Free Height (FH)

The substitute part 5176381-6 maintains complete electrical and mechanical compatibility with the original 176381-6 specification. Both parts share identical connector architecture, contact configuration, and physical dimensions. The primary distinction between these parts is product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 5176381-6 is the direct substitute for the obsolete 176381-6. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting configuration, contact finish, and board height.

The primary distinction is regulatory compliance status. The 5176381-6 carries active product status and RoHS compliance certification, whereas the 176381-6 is classified as obsolete and RoHS non-compliant. Both parts share identical export classification (EAR99) and tariff coding (8536.69.4040).

For new designs and ongoing production applications, the 5176381-6 is the appropriate selection due to its active product status and regulatory compliance. For legacy system maintenance where the original 176381-6 specification is required, the 5176381-6 provides complete functional and mechanical equivalence.
