latigid on Cool, thank you!
Alternate parts and components
the Hirose “798-MDF78S254DSA55|4” is not to get at the moment- any alternatives? (arrow have them, but they want a UID-Number - which i dont have…)
(needet in loopa 4 times)
- Edited
You could consider ordering 798-MDF710S254DSA56 and just offset the row/remove 2x pins so it still sits flat. Or cut it down, but that might look a bit messy!
Elsewise seems to be available at the end of October.
Dremel for the win - as Andy wrote, the good thing with headers is, that you can always shorten them.
Many greets,
Peter
thanks! that are good news! i will go for the shortening thing.

Hi all! after taking a little detour and using another sequencer for a while I’ve decided on the midiphy Seq v4+ and am very excited to get stuck into the build.
Was looking at the BOM and it looks like I can source everything except the 6 x BC817-25LT1G. Any suggestions on an possible alternative?

I had another question regarding an alternative part for the Texas Instruments MC3487N - will this be ok to use in it’s place?
https://au.element14.com/texas-instruments/mc3487ne4/line-driver-quad-rs422-3487-dip16/dp/1210969?st=texas%20instruments%20mc3487n
thanks in advance for assistance
Looks fine!
I think 595-MC3487NE4 also works at Mouser, no?

latigid on ah yes, thanks for the suggestion!
Is there a difference between 517-N2516-6002RB and 517-N2516-517-D2516-6V0C-AR-WE 16pin sockets? Both are one piece on the bom list.
Yep, one is an SMT part for the SD board
For my MatriX: Mouser announced the Bourns Slide Potentiometers (PTL30-15R0-103B1) not before August 2022. As well as the red 8-pin sockets (7-215079-8) are not available.
Has someone an idea where I could get them from, instead?
Hi Robert,
Both would seem to be in stock at Digikey:
https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15R0-103B1/3781301?s=N4IgTCBcDaIAoBUAyBmADAWgIwFYBKmWaKAQliALoC%2BQA

Best regards,

Thanks Andy, found and just ordered. Was not aware of Digikey.

It looks like this resistor
https://www.mouser.com/ProductDetail/KOA-Speer/MF1-4DC3300F?qs=YY4LFJmZXv3lWe8GyUXvKA%3D%3D
can replace this one for the Seq V4+?
https://www.mouser.com/ProductDetail/660-MF1-4DCT52R3300F
Looks good! The difference would seem to be that the in-stock one is “bulk” packaged (i.e., loose), but as there is I think only one per build there shouldn’t be any issue with handling.
Hello.
DIN8 socket what is noted in BOM is out of stock.
Same manufacturer has similar one, but 3 pins don’t match. That’s a bummer.
SDF-80J is in BOM
SDS-80J is with same footprint, but 3 pins are swapped
If I use SDS on all my devices then it should be OK, but if I forget it and use SDF in future and connect BLM then what do I blow up?
