L2006D6TP Equivalent & Substitute Parts

Part Overview

The L2006D6TP is a Logic-Sensitive Gate TRIAC manufactured by Littelfuse Inc., rated for 200V off-state voltage and 6A on-state current in a Surface Mount TO-252 (DPAK) package. This component is classified as Obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts in this category maintain identical mechanical packaging, gate sensitivity characteristics, and thermal operating range while offering alternative voltage ratings to accommodate different application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L2006D6TP are selected based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant across all substitutes:

• Triac Type: Logic - Sensitive Gate
• Current - On State (It (RMS)) (Max): 6 A
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V
• Current - Gate Trigger (Igt) (Max): 5 mA
• Current - Hold (Ih) (Max): 10 mA
• Current - Non Rep. Surge 50, 60Hz (Itsm): 50A, 60A
• Operating Temperature: -40°C ~ 110°C (TJ)
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The primary variable parameter is Voltage - Off State, which determines the maximum blocking voltage capability. Substitute parts with higher voltage ratings (400V and 600V) are direct substitutes for the 200V application, as they maintain all other electrical and mechanical specifications while providing enhanced voltage margin.

Parameter Comparison

Engineering Selection Recommendations

The L2006D6TP is classified as Obsolete, necessitating transition to active product alternatives. Both L4006D6TP and L6006D6TP are Active products manufactured by Littelfuse Inc. and maintain full ROHS3 compliance and REACH Unaffected status.

For applications operating at or below 200V blocking voltage, the L4006D6TP provides direct substitution with 400V rating, offering voltage margin while maintaining identical gate sensitivity and current handling characteristics.

For applications requiring enhanced voltage margin or operating in environments with transient voltage conditions, the L6006D6TP provides 600V blocking voltage rating with identical electrical and mechanical specifications.

Both substitute parts are supplied in Tube packaging and maintain the same TO-252 (DPAK) surface mount configuration, ensuring PCB layout and thermal management compatibility with the original L2006D6TP design.

Frequently Asked Questions (FAQ)

Q: Can L4006D6TP or L6006D6TP be used as direct replacements for L2006D6TP in existing designs?

A: Yes. Both substitute parts maintain identical gate sensitivity (1.3V maximum), current ratings (6A on-state, 5mA gate trigger), thermal operating range (-40°C to 110°C), and TO-252 (DPAK) surface mount packaging. The higher voltage ratings (400V and 600V) do not affect circuit operation in 200V applications and provide additional voltage margin.

Q: What is the primary difference between L4006D6TP and L6006D6TP?

A: The primary difference is the off-state voltage rating. L4006D6TP is rated for 400V blocking voltage, while L6006D6TP is rated for 600V. All other electrical parameters, including gate trigger voltage, current ratings, and thermal characteristics, are identical.

Q: Are there any package or mounting differences between these parts?

A: No. All three parts use identical TO-252-3 (DPAK) surface mount packaging with 2 leads plus tab configuration. PCB footprints and thermal management approaches remain unchanged.

Q: What compliance certifications apply to the substitute parts?

A: Both L4006D6TP and L6006D6TP are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). L6006D6TP carries additional REACH Unaffected status.

Q: Why is the original L2006D6TP classified as Obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. Active alternatives with identical functional and mechanical specifications are available to support design continuity.
