Trying to identify a resistor network

I'm working on a Creative Vibra 16 ISA sound card (CT2260) and it appears to have a damaged resistor network at component RP3. The component has "T1A 102J" printed on it. Its a 5 pin SIP. I can't find any info on it via google and don't know the specs to try and order a replacement. Any help would be appreciated.

Looks like it has been "physically" damaged rather than failed electrically.
Didn't happen to give it a bash getting the card out?
Odd one cannot get any reading on any pair of pins..........

Either way, dime a dozen on any online place.
Word of warning...those surface mount boards were never meant to be repaired and it takes some skill and know how to do any successful mod or repair.

This was a "gift" from my brother. He got it for free from a computer recycler. The card actually works other than the game port.

I agree regarding repairing surface mount gear. Thankfully this component is through hole, so a little hot air, fresh solder, flux, and a desoldering pump should be sufficient for removing it.

I also agree getting no reading between the pins is weird. The package appears a little crooked in the board (the damaged end being raised a little higher than the other end) so who knows what happened to this poor thing.

I think i may just buy a 5-pin sip package rated for 1k ohms and see how that does.

Yes i agree, but maybe the damage took out all internal wiring ?

'102' signifies 1k ohm so replacing the package with 4-off 1k resistors (1/8th watt) would be easy enough. Solder four to the pads in the elongated rectangle PCB marking, fold over the opt wires of all the resistors and solder them to the single 'pad'.
