L2004V3TP Equivalent & Substitute Parts

Part Overview

The L2004V3TP 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 ongoing design support and procurement. The part maintains ROHS3 compliance and operates across the industrial temperature range of -40°C to 110°C.

Parameter Comparison

Engineering Selection Recommendations

L4004V3TP (400 V Rating): This substitute is actively manufactured and maintains full compliance with ROHS3 standards and REACH regulations. It provides a 2x voltage margin over the original L2004V3TP while preserving all gate-trigger and current-handling characteristics. Selection is appropriate for applications where the circuit topology permits higher voltage blocking capability without circuit modification.

L6004V3TP (600 V Rating): This substitute is actively manufactured with equivalent compliance certifications. It provides a 3x voltage margin and is suitable for applications requiring enhanced voltage headroom or for designs operating in higher-voltage environments. All electrical performance parameters remain identical to the L2004V3TP.

Both substitutes are available in active production status with higher inventory levels than the obsolete L2004V3TP, ensuring long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can L4004V3TP or L6004V3TP be used as direct replacements for L2004V3TP?

A: Yes, both parts are direct substitutes from an electrical and mechanical standpoint. They maintain identical gate-trigger voltage, gate-trigger current, hold current, on-state current rating, operating temperature range, and package configuration. The higher voltage ratings (400 V and 600 V) do not affect circuit operation in applications designed for 200 V operation.

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

A: The sole difference is the off-state voltage rating: L2004V3TP is rated 200 V, L4004V3TP is rated 400 V, and L6004V3TP is rated 600 V. All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: L4004V3TP and L6004V3TP both carry ROHS3 compliance and REACH Unaffected status. The L2004V3TP carries ROHS3 compliance. All three parts share identical moisture sensitivity levels and ECCN/HTSUS classifications.

Q: Which substitute should be selected for new designs?

A: Selection depends on the circuit's voltage requirements. For applications operating at or below 200 V, either L4004V3TP or L6004V3TP provides equivalent performance with the advantage of higher voltage margin. L4004V3TP offers a 2x margin, while L6004V3TP offers a 3x margin. Both are actively manufactured with established supply availability.

Q: Is the TO-251AA package identical to the original TO-251 package?

A: The package designation indicates TO-251-3 Short Leads, IPak, TO-251AA configuration for all three parts. The mechanical footprint and pin configuration are identical, ensuring direct PCB compatibility without layout modifications.
