Substitute Part Grouping Explanation

Substitution for the L2004V6TP is determined by the following critical parameters:

Triac Type: Logic - Sensitive Gate configuration must be maintained
Current Rating: On-state current (It (RMS)) must be 4 A or greater
Gate Trigger Characteristics: Voltage (Vgt) and current (Igt) specifications must match or be compatible
Hold Current (Ih): Maximum hold current of 10 mA or less
Mounting Type: Through-hole configuration in TO-251 package required
Operating Temperature Range: -40°C to 110°C minimum
Compliance: ROHS3 compliance required

The L4004V6TP and L6004V6TP are qualified substitutes. Both maintain identical gate trigger specifications, hold current ratings, and thermal operating range. The primary difference is off-state voltage rating: L4004V6TP provides 400 V and L6004V6TP provides 600 V, both exceeding the original 200 V specification. Both substitute parts are active products with current manufacturing status.

Engineering Selection Recommendations

L4004V6TP is the direct voltage-rated upgrade path for the L2004V6TP. This part maintains all electrical and thermal specifications while providing double the off-state voltage rating (400 V vs. 200 V). The L4004V6TP is an active product with current manufacturing support and ROHS3 compliance. Selection of this part is appropriate for applications where the original 200 V specification provides adequate margin.

L6004V6TP provides the highest voltage rating (600 V) among available substitutes while maintaining identical gate trigger and hold current characteristics. This part is also an active product with ROHS3 compliance and current manufacturing status. Selection of this part is appropriate for applications requiring enhanced voltage margin or where system voltage specifications exceed 200 V.

Both substitute parts are manufactured by Littelfuse Inc., ensuring consistent quality and supply chain continuity. The choice between L4004V6TP and L6004V6TP depends on the application's voltage requirements and design margin specifications.

Frequently Asked Questions (FAQ)

Q: Can L4004V6TP or L6004V6TP be used as direct replacements for L2004V6TP?

A: Yes. Both parts maintain identical gate trigger voltage (1.3 V max), gate trigger current (5 mA max), hold current (10 mA max), on-state current (4 A), and operating temperature range (-40°C to 110°C). The TO-251 package and through-hole mounting are identical. The higher off-state voltage ratings (400 V and 600 V respectively) are compatible with applications designed for 200 V operation.

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

A: The L4004V6TP and L6004V6TP differ only in off-state voltage rating. L4004V6TP is rated for 400 V, while L6004V6TP is rated for 600 V. All other electrical and mechanical specifications are identical.

Q: Are the substitute parts available in the same packaging?

A: Yes. Both L4004V6TP and L6004V6TP are supplied in TO-251-3 Short Leads (IPak/V-Pak) configuration, matching the original L2004V6TP package specification.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both L4004V6TP and L6004V6TP are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications as the original part.

Q: Why is the L2004V6TP classified as obsolete?

A: The L2004V6TP is no longer in active production. The L4004V6TP and L6004V6TP represent the current product line for Logic - Sensitive Gate TRIACs in the 4 A current class from Littelfuse Inc.
