Some folks have been inquiring about a cross-reference or substitute for the zener diode ACZRC5373B-G-ND (Manufacturer Number ACZRC5373B-G).
While there is another zener that matches the electrical specifications, it is in a different chip package (DO-214AA, SMB versus the original DO-214AB, SMC). The part number for this replacement is SMBJ5373B-TPMSCT-ND (Manufacturer Number SMBJ5373B-TP) .
