The 9390B meets the specification given in this data sheet.
You may order variants by adding a suffix to the type number.
You may also order options by adding a suffix to the type
number. You may order product with specification options bydiscussing your requirements with us. If your selection option
is for one-off order, then the product will be referred to as
9390A. For a repeat order, ET Enterprises will give the producta two digit suffix after the letter B, for example B21. This
identifies your specific requirement.

Our range of B19A sockets is available to suit the hardpin base.
Our range of B14A sockets is available to suit the B14A cap.
Both socket ranges include versions with or without a mounting
flange, and the versions with contacts for mounting directly onto
printed circuit boards.
