Recommended Board Layout for Receptacle Assemblies
and Individual Receptacles (Type A and B)
Note: All part numbers are RoHS compliant.
J-Receptacle centers may vary depending on requirements. For individual receptacles, minimum nominal centerline
spacing between adjacent receptacles is .150 [3.81]; for receptacle assemblies, centerline spacing between adjacent
receptacles is .156 [3.96]. The .003 [0.08] tolerances are not to accumulate over length of board. For solder mask, see
Tyco Electronics Instruction Sheet 408-7411.
Note: Drawings depict normal use of the contact in a one or two-sided circuit board. When using plated thru-holes,
refer to Tyco Electronics Engineering Report ER-001 and Tyco Electronics Instruction Sheet 408-7411. For solder
mask, see Tyco Electronics Instruction Sheet 408-7411.
