Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the Q8010NH5TP is based on the following critical parameters that must remain compatible:

Fixed Parameters (Non-Negotiable):

• Voltage - Off State: 800 V (all substitutes must match)
• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (mechanical and thermal compatibility)
• Configuration: Single
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowable Variance):

• Current - On State (It RMS Max): 10 A or higher
• Triac Type: Alternistor - Snubberless or Standard (functional equivalence)
• Voltage - Gate Trigger (Vgt Max): 1.3 V to 1.5 V (gate drive compatibility)
• Current - Gate Trigger (Igt Max): 10 mA to 50 mA (gate drive capability)
• Current - Hold (Ih Max): 15 mA to 60 mA (holding current tolerance)
• Operating Temperature: -40°C ~ 125°C or subset thereof

Substitute parts are grouped into two categories: Parametric Equivalents (matching all electrical specifications) and Manufacturer Recommended Substitutes (higher current ratings or alternative gate characteristics within the same voltage class).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent: T1050-8G (STMicroelectronics) is a direct parametric equivalent to Q8010NH5TP. Both devices share identical electrical specifications: 800V off-state voltage, 10A on-state current, 1.3V gate trigger voltage, and Alternistor - Snubberless topology. Both are RoHS3 compliant with -40°C to 125°C operating temperature range. This part is suitable for direct substitution in applications requiring identical performance characteristics.

Manufacturer Recommended Substitutes with Higher Current Ratings: T1235-800G-TR and T1210-800G-TR (STMicroelectronics) provide 12A on-state current with maintained 800V voltage rating and 1.3V gate trigger voltage. T1235-800G-TR retains Alternistor - Snubberless topology identical to the main part. T1210-800G-TR uses Logic - Sensitive Gate topology with reduced gate trigger current (10 mA vs. 50 mA), suitable for applications with lower gate drive capability. Both are RoHS3 compliant.

T2535-800G (STMicroelectronics) provides 25A on-state current for applications requiring higher current handling within the 800V class. Maintains 1.3V gate trigger voltage and Alternistor - Snubberless topology. RoHS3 compliant.

Alternative with Standard Topology: BTA216B-800B,118 (WeEn Semiconductors) provides 16A on-state current with Standard TRIAC topology (non-Snubberless). Gate trigger voltage is 1.5V, within acceptable range. RoHS compliant. Operating temperature maximum is 125°C (no lower limit specified). Suitable for applications where Standard TRIAC characteristics are acceptable and higher current capacity is required.

All substitute parts maintain TO-263-3 D2PAK mechanical compatibility, MSL 1 rating, and 800V off-state voltage specification.

Frequently Asked Questions (FAQ)

Q: Can T1050-8G replace Q8010NH5TP directly? A: Yes. T1050-8G is a parametric equivalent with identical electrical specifications, package, and compliance ratings. No circuit modifications are required.

Q: What is the difference between Alternistor - Snubberless and Standard TRIAC types? A: Alternistor - Snubberless TRIACs are optimized for reduced EMI and do not require external snubber networks. Standard TRIACs may require snubber circuits in certain applications. BTA216B-800B,118 is a Standard type; all other substitutes are Alternistor - Snubberless type matching the main part.

Q: Can I use BTA216B-800B,118 if my application requires -40°C operation? A: No. BTA216B-800B,118 specifies only 125°C maximum operating temperature without a lower limit. If your application requires -40°C to 125°C operation, use T1050-8G, T1210-800G-TR, T1235-800G-TR, or T2535-800G.

Q: What does gate trigger voltage (Vgt) mean for substitution? A: Gate trigger voltage is the minimum voltage required to turn on the TRIAC. Q8010NH5TP requires 1.3V maximum. Substitutes with 1.3V or 1.5V are compatible; lower values provide easier gate drive, higher values require stronger gate signals.

Q: Can I use a higher current-rated substitute like T2535-800G in place of Q8010NH5TP? A: Yes, if your circuit design permits. Higher current-rated devices are backward compatible in applications requiring lower current. Verify that gate drive circuitry can supply the required gate current (35 mA for T2535-800G vs. 50 mA for Q8010NH5TP).

Q: Are all substitutes in the same D2PAK package? A: Yes. All listed substitutes use TO-263-3 D2PAK (2 Leads + Tab) packaging with identical mechanical and thermal characteristics, ensuring PCB layout compatibility.

Q: What is the significance of RoHS3 vs. RoHS compliance? A: RoHS3 Compliant indicates full compliance with current RoHS Directive requirements. RoHS Compliant (BTA216B-800B,118) indicates compliance with earlier RoHS standards. Both are acceptable for most applications; verify specific regulatory requirements for your end application.

Q: Does T1210-800G-TR's lower gate trigger current (10 mA) affect circuit design? A: T1210-800G-TR requires only 10 mA gate trigger current compared to 50 mA for Q8010NH5TP. This allows use of weaker gate drive circuits. Existing circuits designed for 50 mA will operate correctly with T1210-800G-TR; no modifications required.
