Tab count and series fit
The 521384-5 is the 5-tab member of TE Connectivity's Faston quick-disconnect header line, a through-hole right-angle header with a fully insulated black housing. Tab width is 0.250" (6.35mm) and tab thickness is 0.032" (0.81mm); the tin-plated brass contacts suit moderate-cycle applications where corrosion resistance is not the primary concern.
