Any replacement for relay?

Negative. You need a single coil 5v latching type, that one is non-latching.

AL5WN-K is a potential replacement...Lemmie dig into the data sheets.
Edit: Yup. 2 form c, single coil 5v latching, 1&10 coil, 2&9 N/C, 3&8 common, 4&7 N/O. Pins 5 & 6 not used. Fujitsu stopped making these in 2020, but there's some to be found.
I've been looking around a bit for work alikes myself...I'll post more if I find them.

Boom. Easier than I thought.
*Edit*
This is the only one I was able to find after a few mins of sleuthing on mouser.
Double check the pin spacing there...but that should work. I'll dig around digi-key.
Edit again...came up empty handed on digi key. Other possibilities (unconfirmed)

Thanks guys! Yeah, I hit up all the usual sites in my search (and a few dark corners), but came up empty. Used my last one in my VIIB build. It’s not 100% necessary, but would really like the intelligent bypass for the procrastinator board I just got. I may go ahead and snag 1 or 2 from the Newark site since there is someone to vouch the site. Might grab a few of @Stickman393’s suggestions as well in case of fake/failure and maybe just to test and report back.
@Stickman393 looks like the pin spacing will work for the ones on mouser

FWIW, an item like this tends to have 1:1 work alikes from different mfgs. Small signal relays...it's the sort of thing where these used to be used by the billions in telephone switch boards, so if one mfg came up short on qty another could step in easily.
It looks like the 10 pin format was pretty common, but it also appears that many MFGs are getting out of the game fairly recently. Also important to note: there are 3 variations that I've seen thus far in this format:
Non-Latching: contacts use spring force to return to normal position. The relay coil magnetizes and attracts the contacts to their "energized" position, when the coil is de-energized the contacts return to their normal position.
Latching single coil: unit contains only a single relay coil. Applying voltage across the coil induces magnetic force, applying reverse voltage induces magnetic force in opposite direction. That is: apply voltage one way and you get a push, apply the other way and you get a pull. The contacts stay in the same position after voltage is removed.
Latching dual coil: unit contains two coils, energizing one pulls or pushes one way, energizing the other pulls or pushes the other way. I don't know if these function similarly to the single coils in that reversing polarity of voltage reverses magnetic force...this could simply be a more robust version of the previous design. If that's the case, I *wonder* if these COULD be used in place of the single coil latching version. More parts though, and that likely means they're more expensive.

@Harry Klippton ha. It’s so true. Although in this case, I am at the beginning of acquiring my parts for 6 builds, but still will end up paying way more in shipping because I can’t get all parts in one place
. Thanks @fig!
