Part number dissection
ADF6ADF6 identifies the series as a Samtec AcceleRate® HD High-Density 4-Row Socket.
40-03.5-L-4-0-AThe '40' indicates 40 positions per row, resulting in a total of 160 positions for a 4-row connector. The '03.5' specifies a 3.5 mm lead style. The 'L' denotes a plating option of 10 µ" (0.25 µm) Gold on the contact area and Matte Tin on the tail. The '4' signifies four rows. The '0' in this position indicates a specific option, which, based on the ordering guide, is not explicitly defined as an alignment pin option, but rather a placeholder for a specific configuration. The 'A' indicates the presence of an alignment pin.
TRThe 'TR' specifies the packaging as Tape & Reel.
