Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SEAM-50-04.6-S-08-2-A is determined by strict equivalence across the following critical parameters:

• Connector type and gender (High Density Array, Male)
• Position count (400 positions)
• Contact pitch (0.050" / 1.27mm)
• Row configuration (8 rows)
• Mounting technology (Surface Mount)
• Contact material and finish specification (Gold, 30.0µin thickness)
• Height above board (0.240" / 6.10mm)
• Compliance certifications (ROHS3, MSL 1)

The substitute part SEAM-50-04.6-S-08-2-A-K-TR maintains full electrical and mechanical compatibility with the main part number across all specified parameters. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The SEAM-50-04.6-S-08-2-A-K-TR is the direct active equivalent for the obsolete SEAM-50-04.6-S-08-2-A. Both parts maintain identical electrical and mechanical specifications, including connector configuration, contact pitch, position count, and gold contact finish thickness.

Selection of the active substitute part is supported by:

• Identical compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Equivalent moisture sensitivity rating (MSL 1, Unlimited)
• Matching electrical and mechanical parameters across all critical dimensions
• Higher current inventory availability (1847 units versus 845 units)
• Active product status ensuring continued manufacturability and supply

The substitute part includes Pick and Place features in addition to Board Guide functionality, providing enhanced manufacturing flexibility without altering core connector specifications. Packaging is supplied in Cut Tape (CT) format.

Frequently Asked Questions (FAQ)

Q: Are SEAM-50-04.6-S-08-2-A and SEAM-50-04.6-S-08-2-A-K-TR electrically identical?
