L2006D8TP Equivalent & Substitute Parts

Part Overview

The L2006D8TP is a Logic-Sensitive Gate TRIAC manufactured by Littelfuse Inc., rated for 200 V off-state voltage and 6 A on-state current in a surface mount TO-252 (DPAK) package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts maintain identical functional characteristics while offering higher voltage ratings or improved product status.

Substitute Part Grouping Explanation

Substitute parts for the L2006D8TP are qualified based on the following criteria:

Mandatory Matching Parameters:

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): 10 mA
Current - Hold (Ih) (Max): 20 mA
Operating Temperature: -40°C ~ 110°C (TJ)
Mounting Type: Surface Mount
Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation:

Voltage - Off State: Higher voltage ratings are acceptable substitutes for lower voltage applications within the same circuit topology

The L4006D8TP and L6006D8TP are qualified substitutes, offering 400 V and 600 V off-state voltage ratings respectively, while maintaining all other electrical and mechanical specifications identical to the L2006D8TP.

Engineering Selection Recommendations

The L2006D8TP is obsolete and should be replaced in new designs. The L4006D8TP and L6006D8TP are both active products from Littelfuse Inc. and are direct functional equivalents with enhanced voltage ratings.

L4006D8TP (400 V): Select this substitute for applications requiring moderate voltage headroom above the original 200 V specification. This part maintains active product status and full ROHS3 compliance.

L6006D8TP (600 V): Select this substitute for applications requiring maximum voltage margin or for designs operating at higher supply voltages. This part maintains active product status and full ROHS3 compliance.

Both substitutes are packaged in Tube format and are available in higher inventory quantities than the obsolete L2006D8TP, supporting production continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the L4006D8TP or L6006D8TP be used as direct replacements for the L2006D8TP?

A: Yes. Both parts are direct functional equivalents with identical gate trigger characteristics, on-state current ratings, and package specifications. The higher voltage ratings provide additional design margin without affecting circuit operation in 200 V applications.

Q: What is the primary difference between the three parts?

A: The off-state voltage rating is the only electrical difference. The L2006D8TP is rated 200 V, the L4006D8TP is rated 400 V, and the L6006D8TP is rated 600 V. All other parameters are identical.

Q: Are there any package or mounting differences?

A: No. All three parts use the identical TO-252-3 DPAK (2 Leads + Tab) surface mount package with SC-63 designation.

Q: Why is the L2006D8TP obsolete?

A: The L2006D8TP is classified as obsolete by the manufacturer. The L4006D8TP and L6006D8TP are active products and should be used for all new designs and production requirements.

Q: Do the substitute parts have the same compliance certifications?

A: Yes. Both L4006D8TP and L6006D8TP are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the L2006D8TP specifications.

Q: Which substitute should I select for my application?

A: Select based on your circuit's maximum supply voltage. For 200 V applications, either substitute is acceptable. For higher voltage circuits, select the L6006D8TP for maximum margin. The L4006D8TP provides a balanced option for moderate voltage requirements.
