Substitute Part Grouping Explanation

Substitution eligibility for the SEAM-50-04.6-S-10-2-A is determined by strict equivalence across the following critical parameters:

• Connector type classification (High Density Array, Male)
• Position count (500 positions)
• Pitch specification (0.050" / 1.27mm)
• Row configuration (10 rows)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold, 30.0µin thickness)
• Height above board (0.240" / 6.10mm)
• Base product series (SEAM-50)
• Regulatory compliance (ROHS3, MSL 1)

The substitute part SEAM-50-04.6-S-10-2-A-K-TR maintains full electrical and mechanical compatibility with the original specification while offering active product status and improved packaging options.
