Original Part
93.6V Clamp 16A Ipp Tvs Diode Surface Mount DO-214AB (SMC)
Alternative Part
93.6V Clamp 16.1A Ipp Tvs Diode Surface Mount DO-214AB (SMC)
1. SMCJ58A-TP Substitution Conclusion
The SMCJ58A-TP is a highly viable and direct substitute for the original part number 1.5SMCJ58AS_R1_00001. Their core electrical parameters are identical: reverse standoff voltage (58V), minimum breakdown voltage (64.4V), maximum clamping voltage (93.6V), and peak pulse power (1500W). The only minor discrepancy is in peak pulse current (16.1A vs. 16A), which presents no practical difference in surge suppression performance or design compatibility. Both devices share the DO-214AB (SMC) package, enabling a true pin-to-pin replacement. For the vast majority of general-purpose or industrial applications, the SMCJ58A-TP serves as a fully equivalent functional and performance alternative.
2. MSMCJ58A Substitution Conclusion
The MSMCJ58A is also a viable substitute in terms of core electrical parameters and package form factor. Its key distinction lies in its "Military" grade qualification and certification to MIL-PRF-19500. Compared to the original commercial-grade component, the MSMCJ58A undergoes more rigorous quality control, reliability testing, and conformance screening. It is therefore suitable for applications demanding exceptional long-term reliability, environmental robustness, and supply chain quality assurance—such as aerospace, defense, or high-reliability industrial systems. This qualification typically results in a significantly higher unit cost. For applications without specific high-reliability requirements, selecting the MSMCJ58A may lead to unnecessary cost inflation. Conversely, in high-end applications mandating such certification, it represents not merely a substitute but an upgrade in both performance and reliability.
