Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Voltage - Off State: 600 V (exact match required)
• Current - On State (It (RMS)) (Max): 25 A minimum
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V maximum
• Current - Gate Trigger (Igt) (Max): 50 mA maximum
• Package / Case: TO-220-3 (mechanical compatibility)
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C minimum to 125°C minimum
• RoHS Status: ROHS3 Compliant

Substitute Categories:

Category 1: Direct Electrical Equivalents (Alternistor - Snubberless Type)

• BTA24-600BWRG (STMicroelectronics)
• BTB24-600BWRG (STMicroelectronics)

These parts match all primary parameters including Triac Type classification as Alternistor - Snubberless.

Category 2: Functional Equivalent (Standard Triac Type)

• BTB24-600BRG (STMicroelectronics)

This part matches voltage, current, and package specifications but differs in Triac Type (Standard vs. Alternistor - Snubberless).

Category 3: Higher Current Rating (Uprated Substitute)

• T3050H-6T (STMicroelectronics)

This part exceeds the on-state current rating (30 A vs. 25 A) and extends the operating temperature range to 150°C, providing enhanced thermal capability within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): BTA24-600BWRG and BTB24-600BWRG are recommended as primary substitutes. Both maintain identical electrical specifications, Alternistor - Snubberless classification, and ROHS3 compliance. Both are manufactured by STMicroelectronics and available in active product status with high inventory levels.

For Standard Triac Applications: BTB24-600BRG is suitable where Alternistor - Snubberless characteristics are not required. This part maintains all voltage and current ratings but operates as a Standard TRIAC type. Selection depends on circuit snubber network design requirements.

For Thermally Demanding Applications: T3050H-6T provides extended operating temperature range (-40°C to 150°C) and higher on-state current rating (30 A). This uprated substitute is appropriate for applications requiring enhanced thermal margin or higher current capacity within the same TO-220-3 package footprint. Lower gate trigger voltage (1 V vs. 1.3 V) may require circuit evaluation.

All substitute parts maintain ROHS3 compliance, Active product status, and Through Hole TO-220-3 package compatibility with the original Q6025RH5TP.

Frequently Asked Questions (FAQ)

Q: Can BTB24-600BRG replace Q6025RH5TP in all applications? A: BTB24-600BRG matches voltage, current, and package specifications. However, it is classified as a Standard TRIAC rather than Alternistor - Snubberless. Substitution is valid only if the circuit design does not depend on snubberless characteristics. Consult circuit schematic requirements before selection.

Q: What is the difference between Alternistor - Snubberless and Standard TRIAC types? A: Alternistor - Snubberless TRIACs are optimized for operation without external snubber networks, reducing component count and board space. Standard TRIACs may require snubber circuits for EMI suppression. The Q6025RH5TP is Alternistor - Snubberless; substitute parts BTA24-600BWRG and BTB24-600BWRG maintain this classification.

Q: Is T3050H-6T a direct substitute for Q6025RH5TP? A: T3050H-6T is functionally compatible but rated for higher on-state current (30 A vs. 25 A) and extended temperature range (-40°C to 150°C vs. -40°C to 125°C). It is an uprated substitute suitable for applications requiring additional thermal or current margin. Gate trigger voltage is lower (1 V vs. 1.3 V), which may affect circuit triggering behavior.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (BTA24-600BWRG, BTB24-600BRG, BTB24-600BWRG, T3050H-6T) are ROHS3 compliant and REACH unaffected, matching the compliance status of Q6025RH5TP.

Q: What is the significance of Current - Hold (Ih) differences among substitutes? A: Current - Hold (Ih) is the minimum current required to maintain TRIAC conduction after gate signal removal. Q6025RH5TP specifies 50 mA maximum; substitutes specify 75 mA or 80 mA maximum. Higher Ih values do not prevent substitution but may affect circuit behavior in low-current holding conditions. Circuit design should accommodate these differences.

Q: Can these parts be used interchangeably in PCB layouts? A: Yes. All substitute parts use identical TO-220-3 package footprints and Through Hole mounting, ensuring mechanical and electrical compatibility with existing PCB designs without layout modification.
