Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L2008D6TP are qualified based on the following criteria:

Maintained Parameters (Must Match):

• Triac Type: Logic - Sensitive Gate
• Current - On State (It (RMS)) (Max): 8 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): 65A, 85A
• 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)

Variable Parameter (Allows Substitution):

• Voltage - Off State: 200V (main part) → 400V or 600V (substitute parts)

The L4008D6TP and L6008D6TP are direct substitutes with higher voltage ratings, enabling use in applications requiring greater voltage headroom while maintaining identical gate trigger sensitivity and current handling characteristics.

Parameter Comparison

Engineering Selection Recommendations

L4008D6TP (400V Rating): This substitute is Active in product status and maintains full electrical and mechanical compatibility with the L2008D6TP. The 400V off-state voltage rating provides increased voltage margin for applications originally designed for 200V operation. ROHS3 compliance and MSL-1 rating are maintained.

L6008D6TP (600V Rating): This substitute is Active in product status and provides the highest voltage rating among available options. The 600V off-state voltage rating is suitable for applications requiring maximum voltage headroom. ROHS3 compliance and MSL-1 rating are maintained.

Both substitute parts are manufactured by Littelfuse Inc. and are currently in active production, ensuring long-term availability and supply chain stability compared to the Obsolete L2008D6TP.

Frequently Asked Questions (FAQ)

Q: Can L4008D6TP or L6008D6TP be used as direct replacements for L2008D6TP?

A: Yes, both parts are direct substitutes. They maintain identical gate trigger voltage (1.3V max), gate trigger current (5mA max), hold current (10mA max), on-state current (8A max), and operating temperature range (-40°C to 110°C). The only difference is the off-state voltage rating: L4008D6TP is 400V and L6008D6TP is 600V, compared to 200V for the L2008D6TP.

Q: What is the advantage of using a higher voltage-rated TRIAC?

A: Higher voltage ratings provide increased safety margin against voltage transients and overvoltage conditions. If your application operates at or near 200V, selecting a 400V or 600V rated part reduces the risk of voltage-induced failures.

Q: Are the packages identical?

A: Yes. All three parts use the TO-252-3 DPAK (2 Leads + Tab) package, designated SC-63. They are pin-compatible and have identical footprints for PCB assembly.

Q: What is the product status difference?

A: The L2008D6TP is Obsolete, meaning it is no longer manufactured. The L4008D6TP and L6008D6TP are Active products currently in production, ensuring availability for new designs and ongoing production support.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant with MSL-1 (Unlimited) moisture sensitivity level, meeting current environmental and reliability standards.
