Q6004V4TP TRIAC 600V 4A TO-251 Equivalent & Substitute Parts

Part Overview

The Q6004V4TP is a standard TRIAC manufactured by Littelfuse Inc., rated for 600V off-state voltage and 4A on-state current in a TO-251 (V-Pak/I-Pak) through-hole package. This component is actively produced and widely used in AC switching and control applications. Equivalent and substitute parts are identified based on matching electrical ratings, thermal characteristics, and package compatibility to ensure functional interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Q6004V4TP is determined by the following critical parameters:

• Voltage - Off State: 600 V (minimum requirement)
• Current - On State (It (RMS)) (Max): 4 A (minimum requirement)
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V (maximum allowable)
• Package / Case: TO-251-3 Short Leads, IPak, TO-251AA (physical compatibility)
• Operating Temperature Range: -40°C ~ 125°C (TJ) (thermal compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

The T410-600H from STMicroelectronics meets all critical electrical and mechanical parameters required for direct substitution. While the T410-600H is classified as a Logic - Sensitive Gate TRIAC (versus the Q6004V4TP's Standard TRIAC classification), it maintains identical voltage and current ratings, operates within the same temperature range, uses the same package, and meets equivalent compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The T410-600H is an active product from STMicroelectronics with ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the Q6004V4TP. Both components are actively manufactured and available in production quantities. The T410-600H's lower gate trigger current (10 mA vs. 25 mA) and hold current (15 mA vs. 30 mA) reflect its sensitive gate classification, which may reduce gate drive circuit complexity in applications where lower trigger currents are acceptable. The lower non-repetitive surge current rating (30A/31A vs. 46A/55A) should be evaluated against application surge requirements.

Frequently Asked Questions (FAQ)

Q: Can the T410-600H directly replace the Q6004V4TP in existing designs?

A: The T410-600H meets all critical electrical parameters (600V, 4A, 1.3V gate trigger) and uses the same TO-251 package. However, the lower gate trigger and hold currents require circuit evaluation to confirm compatibility with existing gate drive circuits.

Q: What is the difference between a Standard TRIAC and a Logic - Sensitive Gate TRIAC?

A: The T410-600H's sensitive gate classification indicates lower gate trigger current requirements (10 mA vs. 25 mA), which may simplify gate drive design but requires confirmation that the application's gate drive circuit can operate within these specifications.

Q: Are both parts RoHS compliant?

A: Yes, both the Q6004V4TP and T410-600H are ROHS3 compliant and REACH unaffected.

Q: What should be considered when evaluating the non-repetitive surge current difference?

A: The Q6004V4TP has higher surge ratings (46A/55A) compared to the T410-600H (30A/31A). Applications requiring surge protection above 30A should retain the Q6004V4TP or implement additional surge protection circuitry.

Q: Are both parts available in the same package configuration?

A: Yes, both components use the TO-251-3 Short Leads (IPak/TO-251AA) through-hole package and are pin-compatible.
