Key Parameters

Substitute Part Grouping Explanation

The T1650H-6I from STMicroelectronics qualifies as a substitute for the Q6006L5TP based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Voltage - Off State: Both rated at 600 V
• Current - Gate Trigger (Igt) (Max): Both at 50 mA maximum
• Package / Case: Both use TO-220-3 configuration with through-hole mounting
• RoHS Status: Both ROHS3 compliant
• Moisture Sensitivity Level: Both MSL 1 (Unlimited)
• Operating Temperature Range: T1650H-6I supports -40°C ~ 150°C, exceeding Q6006L5TP range

Differing Parameters:

• Current - On State (It (RMS)) (Max): T1650H-6I rated at 16 A versus Q6006L5TP at 6 A
• Voltage - Gate Trigger (Vgt) (Max): T1650H-6I at 1 V versus Q6006L5TP at 2.5 V
• Current - Hold (Ih) (Max): T1650H-6I at 75 mA versus Q6006L5TP at 50 mA
• Triac Type: T1650H-6I is Alternistor - Snubberless versus Q6006L5TP Standard type

The T1650H-6I provides higher current capacity and lower gate trigger voltage, making it suitable for applications where the Q6006L5TP is specified, provided circuit design accommodates the enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the Q6006L5TP and T1650H-6I maintain active product status and full ROHS3 compliance, qualifying them for equivalent use in applications requiring 600V TRIAC functionality with through-hole TO-220 mounting. The T1650H-6I offers superior performance margins with 16A on-state current capacity and lower gate trigger voltage, while maintaining identical off-state voltage and gate trigger current specifications. Selection between these parts should be based on application current requirements and thermal management considerations within the specified operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the T1650H-6I directly replace the Q6006L5TP in existing designs?

A: The T1650H-6I is electrically compatible for 600V applications and uses the same TO-220-3 through-hole package. The higher current rating (16A vs 6A) and lower gate trigger voltage (1V vs 2.5V) represent performance enhancements rather than incompatibilities. Circuit validation is necessary to confirm suitability for specific application requirements.

Q: What is the primary difference between these TRIAC types?

A: The Q6006L5TP is a standard TRIAC, while the T1650H-6I is an Alternistor - Snubberless type. The Snubberless design reduces the need for external snubber circuits in certain AC switching applications, offering simplified circuit design in compatible applications.

Q: Are both parts suitable for the same temperature range?

A: The T1650H-6I supports an extended operating temperature range (-40°C ~ 150°C) compared to the Q6006L5TP (-40°C ~ 125°C). Both are suitable for standard industrial temperature applications, with the T1650H-6I providing additional thermal margin.

Q: Do package differences affect mechanical compatibility?

A: Both parts use TO-220-3 through-hole packages suitable for standard PCB mounting. The Q6006L5TP specifies an isolated tab variant, while the T1650H-6I uses standard TO-220 configuration. Verify thermal management and isolation requirements for your specific application.

Q: What compliance certifications apply to both parts?

A: Both the Q6006L5TP and T1650H-6I are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.30.0080. Both carry MSL 1 (Unlimited) moisture sensitivity rating.
