DIP8 precision resistor networks?

[essele]

I've just found a faulty resistor network on a device I'm repairing and don't seem to be able to find any sensible source for these.

The old part is a BECKMAN 694-3-R10kD, which is a 4x10K 0.5% resistor network in a DIP8 package, with a 0.05% ratio tolerance and a 5ppm TCR tracking tolerance.

These seem to have been obsoleted back in 2013.

I can't actually find much in the way of DIP8 resistor networks in any of the UK suppliers (I've checked Farnell, RS, Mouser and Digikey)

My best option at the moment seems to be to use a surface mount part and mount it on an adapter ... that just seems a bit horrible. Any better approaches here?

Thanks.

Thanks for the responses...

@Vgkid ... they are all 14pin by the looks of it.

@pbarton ... they look ok, just checking on the postage cost.

I found this on mouser. https://eu.mouser.com/ProductDetail/Bourns/4108R-1-103LF?qs=sGAEpiMZZMvrmc6UYKmaNdoL6XYdgUsUcpDkGNC7%2FCg%3D

Even though the pic is a larger package, it says it's DIP-8 in the description. So it'll be using a "stock image"

Hi LateLesley,

Good find, not sure how I missed these, however they are 2% and with generally lower specs. I think I'm still erring of the side of SMT and an adapter.

I suppose another option would be to use four of these:

PTF5610K000BZEB (https://www.mouser.co.uk/ProductDetail/Vishay-Dale/PTF5610K000BZEB?qs=sGAEpiMZZMsPqMdJzcrNwnPpI93fAKplbiQqSM8wfN4%3D)

The absolute TCR is the same as the matching TCR on the BECKMAN part, however I suppose they could heat differently and still blow the original specs.

One could try 4 individual resistors like PTF56.

In SO8 form factor Farnell has AORN and maybe HTRN series resistor, these might be good enough, though not sure.

What performance is actually needed ?  One might get away with more tolerance or higher TC.
