  • Product typeGadgets
  • Two-digit 7-segment layout shows numbers clearly
  • 35 inch digit height for compact instrument panels
  • Common cathode 10-pin interface simplifies wiring
  • Red 11 mcd emission visible in bright ambient light
  • Pack of five displays ready for multi-project use

Two-digit red 7-segment display

The Unique-Bargains 3621AH is a common-cathode LED module showing two decimal digits in a 0.35 inch character height. Each pack contains five identical tubes with a 10-pin DIP footprint and a red plastic face.

Hobbyists and repair techs

Makers building clocks, counters or instrument read-outs will find the 20 mA drive current and 2 V forward voltage straightforward to drive from common logic families. Projects needing more than two digits, a different colour or a common-anode pinout should look elsewhere.

10-pin DIP common-cathode pinout

The single specification that decides fit is the 10-pin common-cathode arrangement with pins 10 and 5 tied to the digit anodes; verify this matches your PCB layout before ordering.

Questions about this item

How can I verify the 3621AH display is working correctly after wiring it up?

Apply 2 V across each segment at 20 mA and confirm all 14 segments per digit light red at roughly 11 mcd.

What comes in the package and what extra parts are needed to drive the displays?

The box contains five 3621AH tubes; you must supply current-limiting resistors and a 10-pin driver or microcontroller.

Which version should I choose if I need common-cathode wiring with 0.35" red digits?

This model is common-cathode with 10 pins and 0.35" red digits; no other version is offered in this listing.
