Maybe MAT12 or SSM2212 for the NPN pair, SSM2220 for the PNP pair. The SSM2220 has the status "last time buy", so it will not be available for long. By the way, apparently the space version of the MAT03, the MAT03S, is still in production.

THAT Corporation 300-series Low-Noise Matched Transistor Array ICs

These are on a modern DI process, and they are all on the same die unlike a comment someone made recently. They both have sub nV noise under similar conditions to the SSM parts, the PNP very slightly quieter due to the different flavor base sheet resistance.

They are marked as "Last time buy" on the Analog Devices site, but they are already out of stock at Mouser, Farnell and Digi-Key. Farnell still has 25 parts kits that contain an SSM2220 and an SSM2212 - but that's a very expensive way to get them.

Maybe some small parts shops still have some lying around, I don't know.

Maybe BF245C or BF545C, or a BF245B (or BF545B) with reduced source resistor (about 390 ohm), or even a BF245A or BF545A with no source resistor at all.
