2.00 mm Pitch, 4 Circuits — the BOM Fit Check
The 1510133204: For a 4-circuit dual-row header, the row spacing is also 2.00 mm, so the total board area is compact — about 4 mm × 4 mm plus the through-hole pads. The blind-mate feature and board guide make this header a good fit for panel-mounted or blind-installation scenarios where the operator cannot see the alignment — common in telecom racks and automotive interior modules.
This is a through-hole solder header (male pin, square contact shape).
