L2004L3TP Equivalent & Substitute Parts

Part Overview

The L2004L3TP is a Logic-Sensitive Gate TRIAC manufactured by Littelfuse Inc., rated for 200 V off-state voltage and 4 A on-state current in a TO-220-3 Isolated Tab package. This component is classified as Obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The part maintains ROHS3 compliance and operates across the industrial temperature range of -40°C to 110°C.

Key Parameters

Substitute Part Grouping Explanation

The L6004L3TP qualifies as a substitute for the L2004L3TP based on the following criteria:

Matching Parameters (Substitution Basis):

• Triac Type: Logic - Sensitive Gate (identical)
• Current - On State (It (RMS)) (Max): 4 A (identical)
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V (identical)
• Current - Gate Trigger (Igt) (Max): 3 mA (identical)
• Current - Hold (Ih) (Max): 5 mA (identical)
• Current - Non Rep. Surge 50, 60Hz (Itsm): 33 A, 40 A (identical)
• Operating Temperature: -40°C ~ 110°C (TJ) (identical)
• Package / Case: TO-220-3 Isolated Tab (identical)
• Mounting Type: Through Hole (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameter:

• Voltage - Off State: L6004L3TP rated at 600 V (versus 200 V for L2004L3TP)

The L6004L3TP represents an upgrade path with enhanced voltage rating while maintaining all other electrical and mechanical specifications. The higher voltage rating provides additional design margin and is backward-compatible in applications where the original 200 V specification is not a limiting constraint.

Parameter Comparison

Engineering Selection Recommendations

The L6004L3TP is the designated substitute for the obsolete L2004L3TP. Selection of the L6004L3TP is supported by the following factors:

• Product Status: The L6004L3TP maintains Active status with current manufacturing support, whereas the L2004L3TP is Obsolete and subject to end-of-life constraints.
• Compliance Continuity: Both parts maintain ROHS3 compliance, ensuring regulatory alignment across design transitions.
• Electrical Compatibility: All gate-level parameters, on-state current, and thermal specifications are identical, enabling direct functional substitution in existing circuit designs.
• Voltage Rating Enhancement: The 600 V off-state rating of the L6004L3TP provides superior voltage margin compared to the 200 V specification of the L2004L3TP, making it suitable for applications requiring the original 200 V specification and those with higher voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can the L6004L3TP directly replace the L2004L3TP in existing designs?

A: Yes. The L6004L3TP maintains identical gate trigger voltage, gate trigger current, hold current, on-state current, surge current ratings, operating temperature range, and package configuration. The higher voltage rating (600 V versus 200 V) does not prevent substitution in applications designed for 200 V operation.

Q: What is the primary difference between these two parts?

A: The L6004L3TP is rated for 600 V off-state voltage, while the L2004L3TP is rated for 200 V. All other electrical and mechanical parameters are identical.

Q: Why is the L2004L3TP classified as Obsolete?

A: The L2004L3TP has reached end-of-life status. The L6004L3TP serves as the active replacement part from Littelfuse Inc.

Q: Are there any package or mounting differences?

A: No. Both parts use the TO-220-3 Isolated Tab package with through-hole mounting, ensuring identical PCB layout and thermal management characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the L2004L3TP and L6004L3TP are ROHS3 compliant.
