    i want to replace a BCR2A smd mount triac with a BT137 through hol triac can it be done with out damaging the Ucontroller
    the BCR2A is drived by a MOC3051 wich is an optoisolated triac

    i have a UC interface an ULN2003 that interface a MOC3051 that command a BCR2A that finaly commandes a low power pump.
    if i replace the BCR2A smd mount triac with a BT137 through hol triac would that dammage the other components such the UC and the MOC3051?

    Looks like both high end voltage specs and power needs would seem to match up with your low voltage demand utilization.(Probably a 110 0r 220 VAC motor drive ? )
    And also the more critical sensitive gate requirements, with that aspect being relevant to the MOC3051 interfacing.
    You will just have to properly mate up the T2 connection physical positioning, as the T1 and gate are the same physical positions. on both units.
