Narrative:

Aircraft X; a B757-300; arrived at gate with upper EICAS message 'spoilers' illuminated after retracting speed brakes. Operation was normal after. Per fault isolation manual (fim) 27-09-00; spoiler control module (scm) 3L faulted. We did not have [manufacturer's] part number (P/north) 285TXXXX-201 (with bite troubleshooting capabilities) available for replacement of [the faulted] scm. I thought I remembered that when our air carrier X received the -300 series B757's we swapped the scm's from the -300 series B757's with the scm's of the [earlier] -200 B757s and the later -200 series B757's. Due to the fact that the -300 series B757s scm's had bite troubleshooting capabilities; versus the fault balls in the early and later -200 series B757's; this helped in troubleshooting.we had P/north 285TXXXX-118 (with fault balls) in stock. I wanted to find out if we could use this part to correct the fault on aircraft X so I contacted maintenance control to verify if that was correct. The maintenance controller; I don't recall his name; stated that we could use the -118 [scm] part for the corrective action [sign-off]. We installed the -118 scm and the operational check [was] good. I was notified in february 2012 that the scm part should not have been used in aircraft X. After being notified; I have researched this issue and found out that per the illustrated parts catalog (ipc) the -118 scm can't be used on B757-300 series aircraft. The contributing factor that caused this was the short amount of time the aircraft was at the gate and us not wanting to delay the aircraft by checking the ipc. So I contact maintenance control for assistance. The corrective action to follow is to take the time to check the ipc for the correct 'effectivity' of parts.

Title: A Lead and Avionic's Mechanic had difficulty getting correct parts information when utilizing their Maintenance Control group for support to help reduce aircraft delays. They replaced a Spoiler Control Module (SCM) with an SCM not 'Effective' for a B757-300 aircraft based on information from Maintenance Control.

Narrative: Aircraft X; a B757-300; arrived at gate with upper EICAS message 'Spoilers' illuminated after retracting Speed Brakes. Operation was normal after. Per Fault Isolation Manual (FIM) 27-09-00; Spoiler Control Module (SCM) 3L faulted. We did not have [Manufacturer's] Part Number (P/N) 285TXXXX-201 (with BITE troubleshooting capabilities) available for replacement of [the faulted] SCM.
