It's highly likely to work if they both support the same voltage, i.e. 3.3V
or
bi-voltage (5V and 3.3V). Early PCI slots are 5V only...

If your system is PCIe with a for-compatibility PCI slot, odds are it
will have 3.3V support.

There's PCIe-to-PCI adapters but the cost is prohibitive for a
one-time use to flash the device.

Most but not all; annoyingly, PowerMac G4 MDD have 64 bits/66 MHz
slots that are 5V only.
They're the ones I wanted an OpenFirmware SAS controller for, as they
have only IDE/PATA
not SATA so really need a storage upgrade. Unfortunately, the 5V-only
killed that
and the SAS controller is now in the SB2500.

I don't have a PCI-X G5, PCIe SAS flashing works in PCIe G5 but adding
the board (flashed
or not) disables the onb-board GbE which is annoying (and as yet
unexplained).

BTW for reference, I have a HP 435709-001 a.k.a. 347786-B21 SAS
controller (or so my ebay history tells me)
that I got for b,7 sometime in late 2019. I see some in the US for
$7.75 plus shipment, so I think it does qualify as a 'cheap option'
:-)
You can find some alternative options with the same (very common) chip in
e.g.

Good luck bringing this Ultra 60 back to life (wish I had one!) & cordially,
