Default Relay Cross References

I was looking for relays. Hella is the OEM supplier on my Sprinter. Hella has a great catalog that searches for its own numbers, superseded numbers and Mercedes numbers well (the search seems to be case sensitive). I can't find the root site for the catalog, but once in, the search seems to work well:

An example search for the Micro relays is shown below:

My Sprinter has a blue Hella 4-pin relay A0025422519 Hella 4RA 9400 10-69. This relay no longer appears in the Hella catalog. The 5-pin 4RD 0077 794-021 that is used by the other 5-pin standard relay slots may substitute.

Some info from my Fuse Map thread.

The smaller sized "Gray" relays.

The Starter Relay is unique to the application. Even though it looks similar in case style to other relays there are no other T1N positions that can be swapped out. As an aside, the large blade relays are more common on the NCV3 models.

Function/position should be verified because it can vary vehicle to vehicle depending upon options ordered from the factory.

The information is a bit jumbled. Sorry, but I'm not inclined to do any more organization. Even just this information took some time to put together.

The information at this site indicates that even though the relay case/connection configuration may be similar, the contact ratings can vary. For example from 10 amps to 30 amps depending upon part number.

Some General Configuration Info


General information: It appears that the starter relay in the T1N models is a one only position. In the NCV3 models it appears that the high amp relay is used in multiple (not all) positions.
