Substitute Part Grouping Explanation

Substitution of the STTH2002G is based on electrical and mechanical parameter equivalence. The primary substitute, STTH2002G-TR, maintains identical electrical specifications across all critical parameters: 200 V reverse voltage rating, 20 A average rectified current, 1.1 V forward voltage drop at 20 A, 40 ns reverse recovery time, and 10 µA reverse leakage current at 200 V. Both devices utilize the same D2PAK surface mount package configuration, ensuring mechanical and thermal compatibility in existing PCB layouts.

The key parameters determining substitution eligibility are:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 20 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 20 A
• Reverse Recovery Time (trr): 40 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Package / Case: TO-263-3, D2PAK
• Mounting Type: Surface Mount

Parameter Comparison

Engineering Selection Recommendations

The STTH2002G-TR is the direct functional equivalent of the STTH2002G. Both devices are manufactured by STMicroelectronics and share identical electrical performance specifications, including reverse voltage rating, forward current capacity, forward voltage drop, and reverse recovery characteristics. Both components comply with ROHS3 and REACH requirements and carry the same ECCN and HTSUS classifications.

The primary distinction between the two parts is product status and packaging format. The STTH2002G is classified as obsolete, while the STTH2002G-TR maintains active product status. The STTH2002G-TR is supplied in Tape & Reel (TR) packaging format, whereas the STTH2002G is supplied in bulk packaging. The STTH2002G-TR also features improved moisture sensitivity characteristics (MSL 1 with unlimited shelf life) compared to the STTH2002G (MSL 3 with 168-hour limitation).

For new designs and ongoing procurement, the STTH2002G-TR is the appropriate selection due to its active product status and superior moisture handling characteristics. For applications requiring the STTH2002G, direct substitution with STTH2002G-TR is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can STTH2002G-TR be used as a direct replacement for STTH2002G in existing designs?

A: Yes. The STTH2002G-TR is electrically and mechanically equivalent to the STTH2002G. Both devices have identical voltage ratings (200 V), current ratings (20 A), forward voltage characteristics (1.1 V @ 20 A), reverse recovery time (40 ns), and package configuration (D2PAK). No circuit modifications are required for substitution.

Q: What is the difference between STTH2002G and STTH2002G-TR?

A: The primary differences are product status and packaging format. The STTH2002G is obsolete and supplied in bulk packaging with MSL 3 moisture sensitivity. The STTH2002G-TR is an active product supplied in Tape & Reel format with MSL 1 moisture sensitivity (unlimited shelf life). Electrical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both devices have identical maximum junction operating temperature (175°C), reverse recovery time (40 ns), and all other electrical performance parameters. Thermal and electrical behavior in circuit operation is equivalent.

Q: What does the "-TR" suffix indicate?

A: The "-TR" suffix indicates Tape & Reel packaging format, which is the standard supply method for high-volume surface mount component procurement. This differs from bulk packaging but does not affect component electrical or thermal performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both STTH2002G and STTH2002G-TR are ROHS3 compliant and REACH unaffected. Both carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the significance of the different MSL ratings?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be stored at specified humidity conditions before requiring baking. STTH2002G has MSL 3 (168-hour limit), while STTH2002G-TR has MSL 1 (unlimited storage). For long-term inventory management, STTH2002G-TR offers superior shelf-life characteristics.
