The B28B-KRWHK-C(LF)(SN): The 2.00mm pitch and 0.256" (6.50mm) row spacing set the PCB footprint for a 2x14 layout. The through-hole termination supports press-fit or solder assembly; the 0.134" (3.40mm) post length is compatible with standard PCB thicknesses.
The mating pitch is 0.079" (2.00mm). Row spacing is 0.256" (6.50mm). The footprint is a 2x14 dual-row layout.
Yes, it is ROHS3 compliant. The (LF)(SN) suffix in the order code indicates lead-free and tin-plated finish.
The (LF)(SN) suffix explicitly marks the ROHS3-compliant, lead-free, tin-plated version. The base B28B-KRWHK-C may be an earlier leaded variant; always specify the full order code for compliance assurance.
