Relay identification for replacement

I’m looking for a cross reference for this relay. I didn’t verify the correct one last time :man_facepalming:t2: Thank you!

The part was made obsolete by Omron nearly 10 years ago because demand was too low to maintain profitability.

Due to a diminishing global demand for the G8P series PCB Power Relay, OMRON will discontinue ALL G8P models at the end of April 2015.

Ref. The old PCN

Omron also said:

there is no direct replacement for this series

The first table in the PCN shows that the housing dimensions, mounting dimensions and wiring are all different from the original in their recommended replacements.

Since the reason for discontinuation was lack of sales, it is extremely unlikely that any other manufacturer would have made a direct replacement for that series.

So your best option is to modify the PCB, or make an adapter PCB, so that you can use a different relay that has the same coil voltage, the same or lower coil current, and the same or higher contact power ratings.

Thank you for your response, I really appreciate it. This part is on my Maytag oven. It appears that the n.c. Pin goes through a resistor to neutral and the (switched) n.o. Pin goes to power.

Let me preface my understanding with the fact that this is my first pcb experience. Please forgive my ignorance.

Theoretically I could make a small pcb (or just use a general purpose relay) to hold a relay and just solder wires to the original pcb according to the contact points?

How do I find the specific voltage/current requirements for my current relay to locate a replacement?

The attached photo is the relay in question.
Thank you again for taking the time to help!!!


Since the schematic doesn’t have the values, you’ll have to locate the data sheet for each relay based on the part numbers.

Now that I know what it goes in to, I’m going to guess you’ll find these do not have standard Omron part numbers.

This is because large appliance manufacturers like Maytag often have sufficient volume to order a custom version of the key parts need. While that keeps the cost down on the circuit making the price lower, it often makes DIY repairs not practical.

Thank you again for the response! I checked the relay by testing ohms on the nc, used a 9v battery to switch the coil and found that the relay was working properly. Upon removal of the pcb one pin was burnt at the joint.

So after testing the relay, I reinstalled it and violá everything worked.

The big question is: was it just a poor pin connection from the factory? Or can I look forward to dealing with this again?

Thank you again for your help, Paul!! I’ll bake a cobbler in your honor! :beers:cheers!

That’s great news!

Bad solder joints almost always make a good connection for at least 3 years and often for 10 to 20. So it’s quite possible you’ve found the only problem and made a permanent fix, congrats!
