Substitute Part Grouping Explanation
Substitution of the Q6035NH5TP is determined by the following critical parameters:
Voltage Rating: All substitute parts must maintain 600V off-state voltage to ensure equivalent electrical isolation and switching capability.
Current Rating: The Q6035NH5TP is rated for 35A on-state current. Substitute parts with lower current ratings (10A, 12A, 16A) are suitable only when circuit design allows operation within their reduced current capacity. Parts with higher current ratings are not provided in the substitute list.
Package Compatibility: All substitute parts use the same TO-263-3 D2PAK surface mount package, ensuring mechanical and thermal compatibility with existing PCB layouts.
Gate Trigger Parameters: Voltage gate trigger (Vgt) and current gate trigger (Igt) specifications vary among substitutes. Lower Vgt values (1V vs. 2V) indicate improved gate sensitivity. Igt values of 35mA or 50mA are functionally equivalent for most applications.
Operating Temperature Range: Substitute parts from STMicroelectronics offer extended temperature ranges (-40°C to 150°C) compared to the main part (-25°C to 125°C), providing additional thermal margin.
Packaging Format: Substitutes are available in Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel® formats to accommodate different manufacturing and procurement workflows.

Engineering Selection Recommendations
All substitute parts listed maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the regulatory and environmental requirements of the Q6035NH5TP. All parts are active products in current production.
Selection of substitute parts depends on circuit current requirements. The Q6035NH5TP operates at 35A maximum on-state current. Circuits designed to operate at or below 10A can use T1050H-6G or T1050H-6G-TR. Circuits operating at or below 12A can use T1235-600G, T1235-600G-TR, T1235H-6G-TR, T1250H-6G, or T1250H-6G-TR. Circuits operating at or below 16A can use T1635-600G, T1635-600G-TR, or T1650H-6G.
For applications requiring extended operating temperature range beyond -25°C to 125°C, STMicroelectronics parts rated to -40°C to 150°C provide additional thermal margin. Parts designated with "H" suffix (T1050H-6G, T1235H-6G-TR, T1250H-6G, T1250H-6G-TR, T1650H-6G) offer 1V gate trigger voltage compared to 1.3V in non-H variants, indicating improved gate sensitivity.
Packaging format selection depends on manufacturing process. Tube packaging suits manual assembly and small-volume production. Tape & Reel (TR) and Cut Tape & Digi-Reel® formats support automated pick-and-place assembly and high-volume manufacturing workflows.
Frequently Asked Questions (FAQ)
Q: Can I use a T1050H-6G (10A) to replace the Q6035NH5TP (35A)?
A: Only if your circuit design operates at or below 10A on-state current. The T1050H-6G maintains the same 600V voltage rating and D2PAK package, but its 10A current rating is the limiting factor. Exceeding this rating will cause device failure.
Q: What is the difference between T1235-600G and T1235H-6G-TR?
A: Both are 12A, 600V TRIAC Alternistors in D2PAK package. The T1235H-6G-TR has a lower gate trigger voltage (1V vs. 1.3V), extended operating temperature range (-40°C to 150°C vs. -40°C to 125°C), and comes in Cut Tape & Digi-Reel® format instead of Tube. The T1235-600G is available in Tube packaging.
Q: Are all substitute parts pin-compatible with the Q6035NH5TP?
A: Yes. All substitute parts use the TO-263-3 D2PAK package with identical pinout: 2 leads plus tab. PCB layout and thermal management remain unchanged.
Q: Which substitute part has the best gate sensitivity?
A: Parts with 1V gate trigger voltage (T1050H-6G, T1050H-6G-TR, T1235H-6G-TR, T1250H-6G, T1250H-6G-TR, T1650H-6G) offer improved gate sensitivity compared to parts rated at 1.3V. Lower gate trigger voltage reduces the gate current required to switch the device.
Q: Can I use T1650H-6G in place of Q6035NH5TP for a 20A application?
A: Yes. The T1650H-6G is rated for 16A on-state current, which exceeds the 20A requirement. However, verify that your circuit design does not exceed 16A sustained current. The device will operate within its electrical specifications at 16A maximum.
Q: What is the difference between Tube and Tape & Reel packaging?
A: Tube packaging contains loose components suitable for manual assembly and small-volume production. Tape & Reel (TR) and Cut Tape & Digi-Reel® formats provide components on carrier tape for automated pick-and-place assembly systems used in high-volume manufacturing.
Q: Do all substitute parts have the same thermal characteristics as the Q6035NH5TP?
A: All parts use the same D2PAK package with identical thermal interface. Operating temperature range varies: the Q6035NH5TP operates -25°C to 125°C, while most STMicroelectronics substitutes extend to -40°C to 150°C, providing wider thermal operating margin.
