Need to know I'm reading this right.

.1 uF 10% 400V

ESR test = 16

Re: Help identify

If I'm reading the markings right, then this should be a good substitute.

I -think- you're right. [Never had to order one of those.]
Don't forget to check lead spacings.

Thanks PCBONEZ.
I made sure to measure H; L; W; and lead space.

FYI
I'm repairing the control board to an Onan generator (300-3056). It's a first gen. board and is obsolete. The replacement board is a third gen. board that cost about $124 to $188 excluding S&H.

I have not seen resistor like the ones on this board.

Hi

Are you sure the cap need substitution?

This type of caps rarely fail, at last in my own experience of more than 40 years sniffing solder fumes...

No, I don't need to replace it now that I know it's a .1uF 400V. An ESR of 16 makes scents now.

UPDATE:

Board was reinstalled. Blew a diode I soldered in backwards.

Replaced 1n4006 diode with 1n4007. Radioshack doesn't have them or in the25 assortment pack.

Board reinstalled. Blew the same diode even though in right direction.
Upon inspection, found 16D nail in cummutator/collector rings area.

With nail removed and 1n4007 replaced, "third times the charm". The board was reinstalled. Finally success! Onan generator running and working fine.

$15 in components saved over a $100 for new board.

Yup, them nails will do it every time!

Re: Help identify

so how did the nail get in the alternator?

Re: Help identify

What was thought to be a 16D nail turned out to be a very rusted/corroded square drive screw. Like the ones holding the floor in the RV it came out of.

More than likely it fell out of rotten RV floor and got lodged somewhere on the generator.
My brother had already cleaned the cummutator and collector rings. My guess is while he was put it back together, it got knocked loose from its' hidding place and ended up in there.

Re: Help identify

I'm a little confused on that .1uF film cap. The picture is of a Roederstein MKT1822 part, but the linked datasheet is for Evox-Rifa MMK series film capacitors (the MMK series was originally from Evox). At any rate, if the dimensions for the part from Digi-Key are correct, it should be fine. Made now by Epcos, it was originally a Siemens part, and the dielectric for it and the original Roederstein part is polyester, which is excellent for GP usage.
