Product details

Comparing circuit counts in the JQ series

The 03JQ-BT is the 3-position entry in the JQ series. For a 4-position version, the 04JQ-BT shares the same pitch, current rating, stack height, and friction lock. The 05JQ-BT and 08JQ-BT extend the row to 5 and 8 positions respectively.

Frequently asked questions

Can I use the 04JQ-BT as a replacement for the 03JQ-BT?

The 04JQ-BT has 4 positions instead of 3, but shares the same pitch, current rating, stack height, and friction lock. It is a functional alternative if your circuit count allows the extra position.
