L2008V6TP Equivalent & Substitute Parts

Part Overview

The L2008V6TP is a Logic - Sensitive Gate TRIAC manufactured by Littelfuse, rated for 200 V off-state voltage and 8 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 continuity. Substitute TRIACs in this family maintain identical gate sensitivity and current ratings while offering higher voltage ratings to accommodate broader application requirements.

Substitute Part Grouping Explanation

Substitute parts for the L2008V6TP are selected based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant across all substitutes:

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: 65 A / 85 A (50/60 Hz)
Operating Temperature Range: -40°C to 110°C (TJ)
Mounting Type: Through Hole
Package / Case: TO-251-3 Short Leads, IPak, TO-251AA

The primary variable parameter is Voltage - Off State, which may be increased in substitute parts. Higher voltage ratings provide enhanced design margin and broader application compatibility while maintaining all other electrical characteristics.

Engineering Selection Recommendations

The L4008V6TP and L6008V6TP are direct functional equivalents to the L2008V6TP with enhanced voltage ratings. Both substitute parts are classified as Active products, ensuring long-term availability and supply chain stability compared to the obsolete L2008V6TP.

Selection between L4008V6TP (400 V) and L6008V6TP (600 V) depends on circuit voltage requirements. The L4008V6TP provides a 2× voltage margin over the original 200 V specification, while the L6008V6TP provides a 3× margin. Both parts maintain identical gate sensitivity, current ratings, and thermal characteristics.

All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity, ensuring compatibility with standard manufacturing and storage practices. Mechanical compatibility is confirmed across all three parts, with identical TO-251 package geometry and lead configuration.

Frequently Asked Questions (FAQ)

Q: Can L4008V6TP or L6008V6TP be used as direct replacements for L2008V6TP?

A: Yes. Both substitute parts maintain identical gate sensitivity (1.3 V maximum), on-state current (8 A), gate trigger current (5 mA), hold current (10 mA), and surge current ratings. The TO-251 package geometry and lead configuration are identical. The higher voltage ratings do not affect circuit operation in applications rated for 200 V or lower.

Q: What is the difference between the three parts?

A: The primary difference is off-state voltage rating: L2008V6TP (200 V), L4008V6TP (400 V), and L6008V6TP (600 V). All other electrical and mechanical parameters are identical.

Q: Why should I select L4008V6TP or L6008V6TP over L2008V6TP?

A: The L2008V6TP is obsolete. L4008V6TP and L6008V6TP are active products with confirmed long-term availability. Both provide enhanced voltage margin for improved design robustness.

Q: Are there any thermal or performance differences between these parts?

A: No. All three parts share identical operating temperature range (-40°C to 110°C), on-state current capacity (8 A), and thermal characteristics.

Q: Do these parts require different PCB layouts or mounting procedures?

A: No. All three parts use the TO-251 through-hole package with identical lead spacing and configuration. Existing PCB designs and assembly procedures are directly compatible.

Q: What is the inventory status for substitute parts?

A: L4008V6TP has 950 pieces in stock. L6008V6TP has 756 pieces in stock. Both are available as new original components.
