    I have a component that im having trouble identifying can any one help.
    5 pin package with markings LA followed with a H on its side and two dots under the LA.
    I have the same circuit as a reference which has the same component in the same place but instead has LA with a U in its side.
    Any help greatly appreciated.

    Welcome to the EP Forum!

    Hrmmm is this a part removed from a PCB? or is it a "new surplus part"??

    If it was removed from a PCB, knowing the PCB function and tracing the connections could help narrow the possibilities and perhaps even suggest a replacement .....

    If it is a surplus "custom" part and you have some number of them that look similar .... The potting looks pretty shoddy perhaps even open-poured .... really it could be anything from a uController/EEPROM/Mosfet/Voltage Reg etc etc.... But at the end of the day not likely worth enough to put much effort into it.

    Good Luck!

    Thanks for the welcoming!!!

    This is removed from a pcb.
    It is a hydraulic servo valve but am unsure of connections at the moment. I will be removing components from a surplus board to identify traces and connections so will shed more light on it later.

    Thanks for reply.

    Thanks for the reply.
    Looking at the data sheet the package with the LA marking is SC82AB which is a 4 leg unless you see something i am missing.
