Substitute Part Grouping Explanation

Substitution eligibility for the QJ6025RH5TP is determined by the following critical parameters:

Voltage - Off State: 600 V (exact match required)
Current - On State (It (RMS)) (Max): 25 A minimum
Triac Type: Alternistor - Snubberless
Package / Case: TO-220-3
Mounting Type: Through Hole

Engineering Selection Recommendations

All substitute parts listed maintain Active product status with full RoHS3 compliance, ensuring regulatory alignment with the QJ6025RH5TP.

BTA24-600CWRG and BTB24-600CWRG provide direct electrical equivalence at 25 A on-state current. These parts operate within -40°C to 125°C junction temperature range, which is 25°C lower than the QJ6025RH5TP maximum. Applications requiring full 150°C thermal headroom should not use these substitutes.

T3035H-6T and T3035H-6I maintain the full -40°C to 150°C operating temperature range of the QJ6025RH5TP while providing 30 A on-state current capacity. T3035H-6I is supplied in insulated TO-220AB package, while T3035H-6T uses standard TO-220 package. Both are suitable for applications requiring thermal performance matching or exceeding the original part specification.

Frequently Asked Questions (FAQ)

Q: Can BTA24-600CWRG or BTB24-600CWRG be used as direct replacements for QJ6025RH5TP?

A: These parts are electrically compatible at 25 A on-state current and 600 V off-state voltage. However, their maximum operating temperature is limited to 125°C junction temperature, compared to 150°C for the QJ6025RH5TP. Use these substitutes only in applications where junction temperature does not exceed 125°C.

Q: What is the difference between T3035H-6T and T3035H-6I?

A: Both parts are identical in electrical specifications and operating temperature range (-40°C to 150°C). The primary difference is package configuration: T3035H-6I uses insulated TO-220AB package, while T3035H-6T uses standard TO-220 package. Select based on thermal isolation requirements in your application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BTA24-600CWRG, BTB24-600CWRG, T3035H-6T, and T3035H-6I are all RoHS3 compliant, matching the compliance status of QJ6025RH5TP.

Q: Can I use T3035H-6T or T3035H-6I in a circuit designed for 25 A operation?

A: Yes. The T3035H series is rated for 30 A on-state current, which exceeds the 25 A requirement. These parts are suitable for 25 A applications and provide additional current margin. No circuit modification is required.

Q: What are the key differences in gate trigger characteristics?

A: The QJ6025RH5TP has a maximum gate trigger voltage (Vgt) of 1.3 V and gate trigger current (Igt) of 50 mA. All STMicroelectronics substitutes have lower gate trigger specifications: 1.0 V maximum Vgt and 35 mA maximum Igt. These lower values indicate easier gate triggering, which is compatible with most gate drive circuits designed for the original part.
