L2004V5TP TRIAC Equivalent & Substitute Parts

Part Overview

The L2004V5TP 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-251 through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts maintain identical current ratings, gate trigger characteristics, and package specifications while offering higher voltage ratings and active product status.

Substitute Part Grouping Explanation

Substitute parts for the L2004V5TP are qualified based on the following criteria:

Maintained Parameters (Substitution Basis):

Triac Type: Logic - Sensitive Gate
Current - On State (It (RMS)) (Max): 4 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): 33 A, 40 A
Operating Temperature Range: -40°C ~ 110°C (TJ)
Mounting Type: Through Hole
Package / Case: TO-251-3 Short Leads, IPak, TO-251AA
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameter (Substitution Differentiation):

Voltage - Off State: 400 V (L4004V5TP), 600 V (L6004V5TP)

The substitute parts are higher voltage-rated variants of the same TRIAC family. These components are pin-compatible and functionally interchangeable in applications where the circuit voltage does not exceed the rated off-state voltage of the substitute part.

Engineering Selection Recommendations

L4004V5TP (400 V Rating): This substitute is suitable for applications where the circuit voltage does not exceed 400 V. The part is active in production status and maintains full compliance with ROHS3 and REACH standards. Selection of this variant is appropriate when the application voltage envelope permits the 400 V rating.

L6004V5TP (600 V Rating): This substitute provides the highest voltage margin within the substitute family and is suitable for applications where the circuit voltage does not exceed 600 V. The part is active in production status and maintains full compliance with ROHS3 and REACH standards. Selection of this variant is appropriate for applications requiring maximum voltage headroom.

Both substitute parts are direct replacements from an electrical and mechanical standpoint, with identical gate trigger characteristics, current ratings, and thermal operating range. The selection between L4004V5TP and L6004V5TP depends solely on the maximum voltage present in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can L4004V5TP or L6004V5TP be used as direct replacements for L2004V5TP?

A: Yes, both substitute parts are pin-compatible and electrically interchangeable in applications where the circuit voltage does not exceed the rated off-state voltage of the substitute part. The gate trigger voltage, on-state current, and hold current characteristics are identical across all three parts.

Q: What is the primary difference between the three TRIAC variants?

A: The off-state voltage rating is the only electrical difference. L2004V5TP is rated for 200 V, L4004V5TP for 400 V, and L6004V5TP for 600 V. All other electrical and mechanical parameters are identical.

Q: Why is L2004V5TP classified as obsolete?

A: The L2004V5TP is listed as obsolete by the manufacturer. The higher voltage-rated variants (L4004V5TP and L6004V5TP) are active products and are recommended for new designs and production applications.

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

A: No. All three parts use the TO-251-3 Short Leads (IPak/V-Pak) through-hole package and are mounted identically on PCBs.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and have MSL rating of 1 (Unlimited). The substitute parts additionally carry REACH Unaffected status.

Q: What voltage rating should I select for my application?

A: Select the substitute part with the lowest voltage rating that exceeds the maximum voltage present in your application circuit. This ensures adequate voltage margin while maintaining optimal component performance.
