Q6010LTH TRIAC Equivalent & Substitute Parts

Part Overview

The Q6010LTH is an internally triggered TRIAC manufactured by Littelfuse Inc., rated for 600 V off-state voltage and 10 A on-state current in a TO-220-3 isolated tab package. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain electrical compatibility across voltage, current, and thermal operating ranges while accommodating packaging and trigger characteristic variations.

Substitute Part Grouping Explanation

Substitution of the Q6010LTH is determined by the following electrical and mechanical criteria:

Primary Compatibility Requirements:

Voltage - Off State: 600 V (exact match required)
Current - On State (It (RMS)) (Max): minimum 10 A
Operating Temperature: -40°C ~ 125°C (TJ) (exact match required)
Mounting Type: Through Hole
Package / Case: TO-220-3 or TO-220-3 Isolated Tab
Configuration: Single
RoHS Status: ROHS3 Compliant

Secondary Variation Parameters:

Triac Type: Internally Triggered (main part) vs. Alternistor - Snubberless, Logic - Sensitive Gate, or Standard (substitute parts)
Current - Gate Trigger (Igt) (Max): varies by substitute type
Current - Hold (Ih) (Max): varies by substitute type
Voltage - Gate Trigger (Vgt) (Max): varies by substitute type

Substitute parts are grouped by on-state current rating (6 A, 8 A, 10 A, 12 A) and TRIAC type. Parts rated at 10 A or higher with 600 V off-state voltage and TO-220 packaging are direct functional equivalents. Parts rated below 10 A are suitable only where circuit design permits reduced current capacity.

Engineering Selection Recommendations

Direct Current Rating Equivalents (10 A):

BTA10-600BRG and BTA10-600CRG are the primary substitutes for Q6010LTH. Both are STMicroelectronics Standard TRIACs rated at 600 V and 10 A with TO-220-3 packaging. BTA10-600BRG features 50 mA gate trigger current; BTA10-600CRG features 25 mA gate trigger current. Both are ROHS3 compliant and active products with established supply availability.

Higher Current Rating Alternatives (12 A):

BTA12-600BRG, BTA12-600CWRG, and BTA12-600TWRG provide increased current capacity at 12 A while maintaining 600 V voltage rating and TO-220-3 packaging. These are suitable where circuit design permits higher current handling. All three are ROHS3 compliant and active products.

Lower Current Rating Alternatives (6 A, 8 A):

BTA06 and BTA08 series parts are suitable only where circuit design permits reduced on-state current capacity. These include Alternistor - Snubberless and Logic - Sensitive Gate variants. All are ROHS3 compliant and active products.

Packaging Consideration:

Q6010LTH uses TO-220-3 Isolated Tab; substitute parts use standard TO-220-3. Verify PCB layout compatibility before selection.

Frequently Asked Questions (FAQ)

Q: Can BTA06 or BTA08 series parts replace Q6010LTH?

A: BTA06 and BTA08 series parts are rated at 6 A and 8 A respectively, below the Q6010LTH 10 A rating. Substitution is possible only if circuit design permits operation at reduced current capacity. Verify load current requirements before selection.

Q: What is the difference between Standard, Alternistor - Snubberless, and Logic - Sensitive Gate TRIAC types?

A: These designations reflect internal trigger architecture and gate sensitivity characteristics. Standard TRIACs (BTA10-600BRG, BTA10-600CRG) provide conventional gate triggering. Alternistor - Snubberless types (BTA06-600BWRG, BTA06-600CWRG, BTA08-600CWRG, BTA12-600CWRG) offer reduced EMI. Logic - Sensitive Gate types (BTA06-600TWRG, BTA08-600SWRG, BTA12-600TWRG) feature lower gate trigger current. Selection depends on circuit requirements.

Q: Is the TO-220-3 Isolated Tab package of Q6010LTH compatible with standard TO-220-3 packages?

A: TO-220-3 Isolated Tab and standard TO-220-3 have identical pin pitch and lead configuration but differ in tab isolation. Verify PCB thermal design and isolation requirements. Standard TO-220-3 packages may require design modification if isolation was critical in the original application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of Q6010LTH.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across -40°C to 125°C (TJ), identical to Q6010LTH.

Q: Which substitute part has the lowest gate trigger current?

A: BTA06-600TWRG and BTA12-600TWRG feature the lowest gate trigger current at 5 mA maximum, classified as Logic - Sensitive Gate types. These are suitable for low-power gate drive circuits.
