Q6015LTTP Equivalent & Substitute Parts

Part Overview

The Q6015LTTP is an internally triggered TRIAC manufactured by Littelfuse Inc., rated for 600 V off-state voltage and 15 A on-state current in a TO-220-3 isolated tab package. This component is active and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining the same package configuration and voltage rating.

Substitute Part Grouping Explanation

Substitution of the Q6015LTTP is determined by the following critical parameters:

Voltage Rating: All substitutes must maintain 600 V off-state voltage
Current Rating: Substitutes must support at least 15 A on-state current (RMS)
Package: All substitutes must use TO-220-3 through-hole configuration
Operating Temperature Range: All substitutes must support -40°C to 125°C
Compliance: All substitutes must be ROHS3 compliant and active status

The substitute parts listed below meet these core requirements. Variations in triac type (internally triggered, alternistor, or logic-sensitive gate), gate trigger voltage, and gate trigger current do not prevent substitution when the primary electrical parameters align.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and REACH unaffected status, matching the Q6015LTTP compliance profile.

Current Rating Consideration: The Q6015LTTP is rated for 15 A on-state current. The substitute parts listed have lower current ratings (6 A to 12 A maximum). Selection of a substitute part requires that the application current demand does not exceed the substitute part's on-state current rating. BTA12-600BRG, BTA12-600CWRG, and BTA12-600TWRG provide the highest current capacity among substitutes at 12 A, approaching the original specification.

Package Compatibility: The Q6015LTTP uses a TO-220-3 isolated tab configuration. All substitute parts use standard TO-220-3 packaging. PCB layout and thermal management considerations may differ due to the isolated tab feature of the original part.

Triac Type Variations: Substitute parts include alternistor (snubberless), logic-sensitive gate, and standard triac types. These functional differences do not prevent electrical substitution when voltage and current parameters are met.

Frequently Asked Questions (FAQ)

Q: Can BTA06-600BWRG, BTA06-600CWRG, or BTA06-600TWRG directly replace Q6015LTTP?

A: These parts maintain the 600 V voltage rating and TO-220-3 package but are rated for 6 A maximum on-state current, which is below the Q6015LTTP 15 A specification. Substitution is valid only if the application current requirement does not exceed 6 A.

Q: What is the difference between BTA12-600BRG, BTA12-600CWRG, and BTA12-600TWRG?

A: All three parts share 600 V voltage, 12 A current rating, and TO-220-3 package. Differences exist in triac type (standard, alternistor snubberless, and logic-sensitive gate respectively) and gate trigger characteristics. Selection depends on gate drive circuit requirements.

Q: Is the isolated tab feature of Q6015LTTP critical for substitution?

A: The isolated tab provides electrical isolation between the tab and the die. Standard TO-220-3 packages used in substitute parts do not include this isolation. If isolation is required for thermal management or safety, substitute parts may not be suitable without additional circuit modifications.

Q: Are all substitute parts in active production status?

A: Yes, all listed substitute parts are active products with current inventory availability and ROHS3 compliance certification.

Q: Can I use BTA10-600BRG or BTA10-600CRG as substitutes?

A: These parts maintain 600 V voltage and TO-220-3 package but are rated for 10 A maximum on-state current. Substitution is valid only if application current does not exceed 10 A.
