Q6006LT Equivalent & Substitute Parts

Part Overview

The Q6006LT is an internally triggered TRIAC manufactured by Littelfuse Inc., rated for 600 V off-state voltage and 6 A on-state current in a TO-220-3 isolated tab package. This component is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across the industrial temperature range of -40°C to 125°C and is RoHS3 compliant with unlimited moisture sensitivity level.

Substitute Part Grouping Explanation

Substitution of the Q6006LT is determined by the following critical parameters:

Voltage Rating: 600 V off-state voltage is mandatory for direct substitution
Current Rating: 6 A on-state current (It (RMS)) is the primary functional requirement
Package Type: TO-220-3 through-hole mounting is required for mechanical compatibility
Operating Temperature Range: -40°C to 125°C must be maintained
Configuration: Single TRIAC configuration only

Substitute parts are grouped by TRIAC type (Internally Triggered, Alternistor - Snubberless, or Logic - Sensitive Gate) and current rating. Parts with 6 A rating provide direct functional equivalence. Parts with 8 A or higher ratings provide uprated alternatives suitable for applications with higher current headroom. Gate trigger characteristics (Vgt, Igt) vary by TRIAC type but do not prevent substitution when the primary electrical parameters are met.

Engineering Selection Recommendations

Direct Equivalents (6 A Rating)

BTA06-600BWRG, BTA06-600CWRG, and BTA06-600TWRG are direct current-rated substitutes for the Q6006LT. All three maintain 600 V voltage rating, 6 A on-state current, TO-220-3 package, and -40°C to 125°C operating range. These parts are manufactured by STMicroelectronics and carry active product status with RoHS3 compliance. Selection among these three depends on gate trigger requirements specific to the application circuit.

Uprated Alternatives (8 A and Higher)

BTA08-600CWRG and BTA08-600SWRG provide 8 A on-state current with identical voltage and temperature specifications. BTA10-600BRG, BTA10-600CRG, BTA12-600BRG, BTA12-600CWRG, and BTA12-600TWRG offer 10 A and 12 A ratings respectively. These uprated parts are suitable for applications where additional current margin is required. All substitute parts maintain RoHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can BTA06-600BWRG directly replace Q6006LT?

A: Yes. Both parts share identical 600 V voltage rating, 6 A on-state current, TO-220-3 package, and -40°C to 125°C operating temperature. BTA06-600BWRG is manufactured by STMicroelectronics and carries active product status.

Q: What is the difference between BTA06-600BWRG, BTA06-600CWRG, and BTA06-600TWRG?

A: All three maintain 600 V voltage and 6 A current ratings. The differences lie in gate trigger characteristics: BTA06-600BWRG has 50 mA hold current, BTA06-600CWRG has 35 mA hold current, and BTA06-600TWRG has 10 mA hold current. Selection depends on gate drive circuit requirements.

Q: Can I use BTA12-600CWRG instead of Q6006LT?

A: Yes. BTA12-600CWRG maintains 600 V voltage rating and TO-220-3 package with uprated 12 A on-state current. This provides additional current capacity for the same voltage and temperature specifications. The part is RoHS3 compliant and carries active product status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts from STMicroelectronics carry RoHS3 compliance status, matching the Q6006LT specification.

Q: What is the package difference between Q6006LT and BTA06-600BWRG?

A: Q6006LT uses TO-220-3 Isolated Tab package, while BTA06-600BWRG uses standard TO-220-3 package. Both are through-hole mounted with identical pin configuration and thermal characteristics for most applications. Verify isolated tab requirement in your specific circuit design.
