1. SMCJ58A Substitution Conclusion Based on key electrical parameters, package, and functionality, the Littelfuse SMCJ58A can serve as a direct replacement for the Panjit 1.5SMCJ58A_R1_00001. Both devices share identical reverse standoff voltage (58V), minimum breakdown voltage (64.4V), maximum clamping voltage (93.6V), and peak pulse power (1500W). Each is housed in a DO-214AB (SMC) package. The only minor deviation is in peak pulse current, rated at 16.1A versus 16A respectively. This 0.1A difference falls well within typical engineering tolerances and does not affect surge protection performance at the same voltage level. The SMCJ58A is electrically and mechanically compatible as a drop-in replacement, requiring no circuit modifications.

2. SMCJ58A-TP Substitution Conclusion The MCC SMCJ58A-TP is also a qualified substitute for the original part. All core parameters—58V standoff voltage, 93.6V clamping voltage, and 1500W peak power—match the original specification exactly. Its peak pulse current of 16.1A is the same as that of the SMCJ58A. The “-TP” suffix typically denotes tape-and-reel packaging variations and does not impact the device’s electrical characteristics. There is no functional difference in circuit protection behavior, power dissipation capability, or mounting compatibility. The part can be used as a direct replacement, provided the PCB layout and pad design are fully compliant with the SMC package standard.
