Substitute Part Grouping Explanation

Substitute parts for the TS20P02GHD2G are identified based on strict electrical and mechanical parameter matching. The substitution logic is organized into two categories:

Direct Manufacturer Substitutes (Taiwan Semiconductor Corporation): Parts TS20P02GH and TS20P02G are variants within the same manufacturer's product line. These components share identical electrical specifications including 100 V peak reverse voltage, 20 A average rectified current, 1.1 V forward voltage drop at 20 A, and 10 µA reverse leakage current at 100 V. All three parts operate across the same temperature range (-55°C to 150°C), utilize the same through-hole TS-6P package, and maintain automotive-grade qualification with AEC-Q101 certification. The primary distinction is product status: TS20P02GH and TS20P02G are currently active, whereas TS20P02GHD2G is discontinued.

Cross-Manufacturer Parametric Equivalent (Fairchild Semiconductor): The DFB2010 from Fairchild Semiconductor meets the core electrical requirements of 100 V peak reverse voltage and 20 A average rectified current with identical forward voltage characteristics (1.1 V @ 20 A). This part shares the same through-hole mounting configuration and TS-6P package footprint. The reverse leakage specification differs at the measurement point (10 µA @ 50 V versus 10 µA @ 100 V), but the leakage current magnitude remains equivalent. Operating temperature range and RoHS3 compliance are maintained.

Engineering Selection Recommendations

Primary Recommendation: TS20P02GH

The TS20P02GH is the preferred direct substitute for the discontinued TS20P02GHD2G. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, automotive-grade qualification (AEC-Q101), and RoHS3 compliance. The TS20P02GH maintains active product status with 1054 units in stock, ensuring supply chain continuity. No design modifications or circuit re-evaluation are required for this substitution.

Secondary Recommendation: TS20P02G

The TS20P02G serves as an alternative direct substitute from Taiwan Semiconductor Corporation with equivalent electrical performance and automotive qualification. This part is also in active production with 886 units available. Selection between TS20P02GH and TS20P02G depends on inventory availability and procurement lead times, as both components are functionally interchangeable.

Cross-Manufacturer Alternative: DFB2010

The DFB2010 from Fairchild Semiconductor is a parametric equivalent suitable for applications where Taiwan Semiconductor components are unavailable. This part meets all critical electrical requirements including voltage and current ratings, forward voltage characteristics, and operating temperature range. The DFB2010 maintains the same through-hole TS-6P package configuration and is available in high quantity (1935 units). The reverse leakage measurement point differs (50 V versus 100 V), but the leakage current magnitude of 10 µA remains equivalent. RoHS compliance status for the DFB2010 is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can TS20P02GH be used as a direct replacement for TS20P02GHD2G without circuit modifications?
