I've never bothered to pore over the datasheet to see what/if there is any difference... I always just buy the 2803A variants.
Intellitouch low voltage circuit breaker tripping.

I'm not a pool expert but they look to be the same, maybe an electronics engineer would know the difference. Even Amazon list them the same. Curious to see what you find out, as I am still learning from the pros on here. Hope it works for you.
UNL2803A or APG
A = Die REV where they added internal pull up resistors on the inputs..
P = Plastic DIP package
G = Green or Lead Free device
So.. either one should work just fine.

Transistors in. Powered up board. No tripping. Powered down and connected all the sensors, controls and relays. Powered all breakers up. No tripping. Tried to turn on pump. Nothing. Well, not nothing, swearing.
Opened up panel a stared menacingly at the board with my best Clark Griswold expression. Tried to turn on pump again. Eureka! pumps running. I guess the remote needed some time to transfer it's config to the system again.
Thanks you for your help gentlemen. My youngest son is so happy he no longer needs to be my pool stirrer when I dose the pool.

That's great news Oz, glad we could help! Those transistor arrays blow up quite a bit and I'm glad they decided to socket them.
Also, whenever I re-power my system (intellitouch and pump together), I have to reset the Intellitouch before it will talk to the pump.

Yeah, I have stashed 6 more of those arrays in an antistatic envelope in the panel behind the mainboard with a note for myself or the next owner.
Sorry for resurrecting an old thread but I had to say thank you. THANK YOU! This thread saved me from having to buy a new board or a rebuild. I had the exact same symptoms and the transistors did the trick for me as well. Just made my weekend!
