2 x 3 mm, Bi-level PCB Mount LED Indicator, G2178B Series The G2178B series is an assembly using two 2 x 3 mm LEDs in a right-angle mount. Designed to save panel space, the assembly measures just over 4.3 mm(0.170") in width. Long arrays should be located on a pitch of 4.4 mm(0.173") to avoid crowding and tolerance build-up. This series can also be supplied with pinout reversed from that shown by adding “-RL” to the order code of the part number. 4.3 (0.17) 9.0(.355) 2.5±.5 2 typ 5.08 9.65 2.54 3.5 min 2.54 5.08 2.54 Red or yellow Anode Green Anode + – (Pinout for single color) (typ for bi-color) Specify part desired as follows: G2178B/Order Code LED1 + Order Code LED 2 For example: “G2178B/G+Y” designates an assembly with a green LED on top and a yellow LED on the bottom. “G2178B/(G+Y)-RL” designates the same assembly with leads reversed.
