Equivalent & Substitute Parts for Q8016NH6TP

Part Overview

The Q8016NH6TP is a TRIAC Alternistor (Snubberless) manufactured by Littelfuse, rated for 800 V off-state voltage and 16 A on-state current in a Surface Mount TO-263 (D2PAK) package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while accommodating application requirements for current rating, gate sensitivity, and thermal characteristics.

Substitute Part Grouping Explanation

Substitution of the Q8016NH6TP is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain 800 V off-state voltage to ensure equivalent blocking capability.
Package Compatibility: All substitutes use TO-263-3 D2PAK surface mount package, ensuring mechanical and thermal interface compatibility.
Gate Trigger Voltage (Vgt): Maximum 1.3 V across all parts ensures compatible gate drive requirements.
Operating Temperature Range: -40°C to 125°C junction temperature maintained across all substitutes.
Compliance: RoHS3 compliance and REACH unaffected status required for regulatory equivalence.

Current rating variations (12 A, 16 A, 25 A) and gate sensitivity differences (standard vs. sensitive gate) create distinct substitution categories based on application current requirements and gate drive circuit design.

Engineering Selection Recommendations

T1210-800G-TR (STMicroelectronics): This Logic - Sensitive Gate TRIAC is suitable for applications where the Q8016NH6TP current rating of 16 A exceeds circuit requirements. The 12 A maximum on-state current and 10 mA gate trigger current support low-power gate drive circuits. Active product status and RoHS3 compliance maintain regulatory equivalence.

T1235-800G-TR (STMicroelectronics): This Alternistor - Snubberless TRIAC matches the Q8016NH6TP triac type classification and provides 12 A on-state current. The 35 mA gate trigger current and 35 mA hold current represent intermediate gate sensitivity. Active product status and RoHS3 compliance are maintained.

T2535-800G (STMicroelectronics): This Alternistor - Snubberless TRIAC provides 25 A on-state current, exceeding the Q8016NH6TP 16 A rating. Selection is appropriate for applications requiring higher current capacity within the same 800 V voltage class and D2PAK package. Active product status and RoHS3 compliance are maintained.

All substitute parts maintain identical off-state voltage (800 V), gate trigger voltage maximum (1.3 V), operating temperature range (-40°C to 125°C), and package configuration (TO-263-3 D2PAK), ensuring thermal and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can T1210-800G-TR replace Q8016NH6TP in all applications?

A: T1210-800G-TR is suitable only for applications where 12 A on-state current is sufficient. The Q8016NH6TP is rated for 16 A; applications requiring this full current capacity must use T2535-800G or equivalent 16+ A rated devices.

Q: What is the difference between Alternistor and Logic gate TRIAC types?

A: Alternistor (Snubberless) and Logic (Sensitive Gate) represent different internal gate circuit designs. Both maintain 800 V voltage rating and 1.3 V maximum gate trigger voltage. Gate trigger current (Igt) and hold current (Ih) differ, affecting gate drive circuit design requirements.

Q: Are all substitute parts in the same package?

A: Yes. All listed substitutes use TO-263-3 D2PAK (2 Leads + Tab) surface mount package, ensuring identical PCB footprint and thermal interface compatibility with Q8016NH6TP.

Q: Do substitute parts maintain RoHS3 compliance?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, matching the regulatory status of Q8016NH6TP.

Q: Which substitute should be selected for higher current applications?

A: T2535-800G provides 25 A on-state current rating, exceeding the Q8016NH6TP 16 A specification. This part is appropriate for applications requiring current capacity beyond 16 A within the 800 V voltage class.

Q: Can gate drive circuits designed for Q8016NH6TP (80 mA Igt) be used with T1210-800G-TR (10 mA Igt)?

A: Gate drive circuits designed for higher gate trigger current (80 mA) will function with lower-current devices (10 mA), as the gate drive will exceed minimum requirements. Circuits designed for lower gate trigger current may not reliably trigger higher-current devices.
