I’m kind of an electronics newbie and apologize beforehand if this is a stupid question and I’m pretty sure the answer is basically yes, but I thought I would post to be sure. I’m repairing a speed circuit board on a power tool and need to replace a small AC transformer but am having trouble locating a similar device. I found the following part on digikey that appears to be an exact replacement, but have contacted them and they’ve indicated that it is an obsolete part and they can no longer get it.
Attached is the datasheet for the transformer, part number BV020-5411.0 This is a small 115v primary/6v secondary, 58mA (0.35VA), epoxy encapsulated transformer, PCB mount with 15mm spacing on primary pins and 5mm on secondary pins (15mm between primary and secondary). I’ve done some exhaustive online searching and haven’t been able to come up with another direct equivalent. But it appears that I might have better luck finding a 230v/12v version with a similar pinout. If I can use the 230v/12v one instead, do I need to find one capable of 0.35VA, or do I actually need double that (0.70VA) since I will be using it in a 115v application?
Furthermore, I’ve found several transformers with dual primary/dual secondary windings that may also work. Could I use a transformer with two 115v inputs, and two 6v outputs and wire the primaries in parallel and the secondaries in parallel? I would need to slightly modify the pins and add a couple jumper wires under the transformer to make it fit, but I suppose that could be an alternative.
