Key Parameters

Substitute Part Grouping Explanation

The Q4006N4TP qualifies as a direct substitute based on the following alignment criteria:

Matching Parameters:

• Triac Type: Standard (identical)
• Current - On State (It (RMS)) (Max): 6 A (identical)
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V (identical)
• Current - Gate Trigger (Igt) (Max): 25 mA (identical)
• Current - Hold (Ih) (Max): 50 mA (identical)
• Current - Non Rep. Surge 50, 60Hz (Itsm): 65A, 80A (identical)
• Configuration: Single (identical)
• Operating Temperature: -40°C ~ 125°C (TJ) (identical)
• Mounting Type: Surface Mount (identical)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)

Distinguishing Parameter:

• Voltage - Off State: Q4006N4TP is rated for 400V, compared to Q2006N4TP at 200V. This represents an upgrade in voltage capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Q4006N4TP is suitable for applications currently using the Q2006N4TP. The substitute maintains identical electrical characteristics for gate trigger voltage, on-state current, hold current, and surge current specifications. The increased off-state voltage rating of 400V provides enhanced overvoltage capability compared to the original 200V specification.

The Q4006N4TP carries Active product status, ensuring continued availability and manufacturing support. Both components meet ROHS3 compliance requirements and share identical moisture sensitivity classification, thermal operating range, and Surface Mount TO-263 packaging. The substitute is available in Tube packaging format.

Frequently Asked Questions (FAQ)

Q: Can Q4006N4TP directly replace Q2006N4TP in existing designs?

A: Yes. The Q4006N4TP maintains identical on-state current (6A), gate trigger voltage (1.3V maximum), hold current (50mA maximum), and surge current ratings (65A/80A). Both components use the same TO-263 (D2PAK) package with identical pinout and thermal characteristics. The higher voltage rating of Q4006N4TP (400V vs. 200V) is compatible with applications designed for 200V operation.

Q: What is the primary difference between these two parts?

A: The Q4006N4TP is rated for 400V off-state voltage, while the Q2006N4TP is rated for 200V. All other electrical parameters, including current ratings, gate trigger specifications, and thermal characteristics, are identical. The Q4006N4TP also has Active product status compared to the Obsolete status of Q2006N4TP.

Q: Are the packages identical?

A: Yes. Both parts use the TO-263-3 (D2PAK with 2 Leads + Tab) package. Pin configuration, lead spacing, and mounting footprint are identical, allowing direct PCB substitution without layout modifications.

Q: What compliance certifications apply to both parts?

A: Both Q2006N4TP and Q4006N4TP are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Why is Q2006N4TP marked as Obsolete?

A: The Q2006N4TP has reached end-of-life status. The Q4006N4TP, with its higher voltage rating and Active product status, serves as the recommended alternative for new designs and ongoing procurement.
