The 79257-434HLF: The 0.100" pitch and row spacing set a standard footprint. Insulation height of 0.190" (4.83mm) is the standoff from the board surface to the bottom of the housing. Through-hole termination gives a stronger mechanical anchor than SMT for this pin count, especially under cable strain. The right-angle form factor keeps the connector body low-profile in the z-axis, which matters when the board sits in a tight enclosure.
The base product number is 79257; the -434HLF suffix encodes the plating, pin length, and packaging variant.
