I need to find a replacement ON semiconductor part labeled 633 LE. This part was connected directly across the 12 V DC input jack of an Agilent U2702 oscilloscope to protect against accidental polarity reversal. Agilent, now Keysight, Will not offer any help as I have already contacted them. Regards, George Crochiere, National Technical Systems, 413-499-2135, EXT 124

You part marking corresponds to the NCP4626DSN033T1G Linear Voltage Regulator, LDO, 300 mA, with Reverse Current Protection.
