Key Parameters

Substitute Part Grouping Explanation

Substitution for the ES1G-LTPS01 diode is governed by strict adherence to the following key parameters: voltage rating (400 V), average rectified current (1A), forward voltage (1.25 V @ 1A), reverse recovery time (35 ns), speed classification (Fast Recovery), reverse leakage current, capacitance, surface mount configuration, package/case type (DO-214AC, SMA), and operating junction temperature range (-65°C ~ 175°C). Alternate part numbers are grouped solely if all the aforementioned specifications are matched or within the explicitly stated tolerances.

Parameter Comparison

Engineering Selection Recommendations

The ES1G-LTP is currently active and available in substantial inventory. The substitute part maintains all key electrical and mechanical parameters consistent with ES1G-LTPS01. The ES1G-LTP is ROHS3 compliant and REACH unaffected, confirming its suitability for applications requiring current compliance standards. The obsolete status of ES1G-LTPS01 necessitates transition to ES1G-LTP for ongoing engineering and supply reliability.
