Folks:

The current BOM for the SSR4 w/DMX option at Mouser has three problematic items:

*The Littlefuse clips are end of life; I believe these are compatible replacements: You are not allowed to view links. Register or Login

*The 180-ohm resistors are now only sold as reels under that product number; I believe this is the number for onesies/foursies: You are not allowed to view links. Register or Login

*The RS-485 chip is EOL (I believe ST is getting out of the buffer/line-driver business, as all its products in that category are EOL); I have been using this alternate part in other, similar projects: You are not allowed to view links. Register or Login

Could the Powers That Be please review my suggested replacements and, first, bless them (as I'd like to build the controller in the coming days), and then update the BOM with either my suggestions or (should I have made any mistakes) ones that are appropriate?

Thanks.

\dmc

PS: FWIW, the "Base SSR4" BOM has the same clip and resistor problems. The "DMX Option" looks to be the BOM for the v1 board, not the current V2 board (i.e.: it shows the obsolete Pulse transformer and has the obsolete capacitors) and additionally has the EOL ST RS-485 chip.

PPS: Just saw -- this is Post No. 666 for me. I was always a little devilish ;-) ...

I believe this should work. The fuse clip is the only thing I am not positive about until someone trys them.

RJ:

Thanks. I'll order the BOM with those substitutes today.

I'll be buying the new clips but I have a stash of the old ones (I wonder why I bought spares?), so if the new new ones aren't right, I'll still be OK.

PS: Happy Thanksgiving.

Please let us know the results and if the parts work, the BOM shoul be updated.

I should have the parts mid-week next week and plan to build ASAP. I have a new BOM with the new parts over at Mouser and will publish it and change the wiki link when all is proven well.

Did these parts work for you? I've got several empty boards i need to build and the BOM was never updated. Just curious if they worked for you? Also there is now another obsolete part.

Did these parts work for you?

My plans changed last year and I didn't need the device for the show. In fact, I was totally surprised the other day when I found a box from Mouser with the parts ... when I saw the transformer, I quickly figured out they were for an SSR4.

While I still don't need this one, let me see if I can get its building onto the agenda sometime in the next few days.

Thanks.

cool, it will be at least next week before i get to order the parts to attempt to build mine but it would be nice to have verification that all of the substituted parts work or not before i order. Thanks for all of your help here and on my WTB post. And once i build mine i will also confirm that mine works using the substituted rs485 chip with 595-SN75176BP. But if SABIE still has a few of the old rs485's i might get a few from him just in case the substitution has any issues.

That part will work but i believe it is not rated for very cold temps as I remember that is my only concern with it as a replacement.

This is what I ordered for the SSC coop.
DS3695TN/NOPB
It is about 50 cents more but it is good down to -40.

Has the Bom been updated with Rj approved substitutes?
