1. P6KE10AS_AY_00001 Substitution Conclusion
Substitution is acceptable, with a minor note regarding the derating of peak pulse current. Compared to the original part, this device offers identical key parameters: clamping voltage (14.5V), reverse stand-off voltage (8.55V), and peak pulse power (600W). The package is also the same, ensuring direct compatibility in both electrical characteristics and physical mounting. The only difference lies in its peak pulse current (Ipp) of 41A, which is slightly lower than the original's 42.1A. Consequently, under an identical maximum transient surge, this device will theoretically experience marginally higher stress, though its 600W power handling capability remains unchanged. For the vast majority of applications, this discrepancy falls within standard engineering margins and should not preclude its use as a functional substitute. However, it should be evaluated in designs demanding extreme precision or operating near the absolute limits of the component.
2. P6KE10A_R2_00001 Substitution Conclusion
Substitution is acceptable, with the same condition regarding minor peak pulse current derating as noted for the P6KE10AS_AY_00001. This part shares identical technical specifications with the aforementioned P6KE10AS_AY_00001. The sole deviation from the original part is the same minor difference in peak pulse current (41A vs. 42.1A). This similarly results in a subtle performance variation when handling the maximum rated transient current, while the core clamping protection level and power rating are preserved. Given that the differentiating parameter is consistent between these two substitutes, the feasibility conclusion for this part is identical. It can serve as a direct replacement for the original part.
