No soldering in the harness. ## Active Lifecycle — No Obsolescence Pressure There is no end-of-life notice, no last-time-buy date to track. ## Pitch and Position Count — Board Fit Check At 0.156\" (3.96mm) pitch, this housing matches the standard SL-156 header footprint. The 24 positions in a single row give a total body width of about 3.74 inches (95 mm) across the mating face. That is a wide connector — plan for board real estate and wire bundle routing accordingly. The pitch is generous enough for 18-22 AWG wire without crowding the crimp pockets.","metaTitle":"TE Connectivity 2-640251-4 SL-156 Receptacle Housing, 24 Pos","metaDescription":"TE Connectivity SL-156 24-position receptacle housing, 0.156\" (3.96mm) pitch, natural PA66.
