NOTES:
1. Dimensions are in inches.
2. Metric equivalents are given for information only.
3. Unless otherwise specified tolerances are ±.005 inch (0.13 mm) for three place decimals and ±.01
inch (0.3 mm) for two place decimals.
4. A recess to be provided to fully enclose the head or nut of the fastener below the surface of the
socket.
5. Contact terminations may be round, squared, or rectangular.
6. Devices shall accept flat leads .008 inch (0.20 mm) to .015 inch (0.38 mm) thick by .015 inch (0.38
mm) to .021 inch (0.53 mm) wide. The values for mating forces are based upon the use of
standard leads .011 ±.002 inch (0.28 ±0.05 mm) thick by .018 ±.002 inch (0.46 ±0.05 mm) wide.
The length of the lead accepted by the device shall be .150 inch (3.81 mm). Contact shall be
made at or before reaching a depth of .100 inch (2.54 mm).
7. A visual polarization index shall be provided in the first quadrant. If the visual index overlaps into
the fourth quadrant, it shall be adjacent to or clockwise from contact number one.
8. It is desirable that the socket face shall be relieved to facilitate removal of the integrated circuit.
9. Ramped edges optional. Configuration of edges optional.
10. Standoffs optional for termination type I leads.
11. All dimensions of configuration 1 are applicable to configurations 2 and 3.
12. For termination type II, there shall be a minimum of 2 standoffs. The configuration and location of
the standoffs is optional.
