Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Q8025R6TP is determined by the following criteria:

Primary Matching Parameters:

• Voltage - Off State: 800 V (exact match required)
• Current - On State (It (RMS)) (Max): 25 A (exact match required)
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V (exact match required)
• Package / Case: TO-220-3 (exact match required)
• Mounting Type: Through Hole (exact match required)
• Configuration: Single (exact match required)

Secondary Compatibility Parameters:

• Operating Temperature Range: -40°C to 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Variations in Current - Non Rep. Surge (Itsm), Current - Gate Trigger (Igt) (Max), and Current - Hold (Ih) (Max) are within acceptable tolerance ranges for this product category and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the Q8025R6TP.

BTA24-800BWRG and BTB24-800BWRG are Alternistor - Snubberless variants, functionally equivalent to the Q8025R6TP in triac type classification. Both parts feature reduced gate trigger current (50 mA vs. 80 mA) and reduced hold current (75 mA vs. 100 mA), with higher non-repetitive surge current ratings.

BTB24-800BRG is a Standard TRIAC variant with identical electrical ratings except for hold current (80 mA vs. 100 mA). This part differs in triac type classification but maintains all primary voltage and current specifications.

Selection among these substitutes depends on application-specific requirements regarding triac type (Snubberless vs. Standard) and gate drive characteristics.

Frequently Asked Questions (FAQ)

Q: Can BTA24-800BWRG replace Q8025R6TP directly? A: Yes. BTA24-800BWRG matches all primary electrical parameters (800 V off-state voltage, 25 A on-state current, 1.3 V gate trigger voltage) and package specifications (TO-220-3, through-hole mounting). Both are Alternistor - Snubberless variants with identical operating temperature range and RoHS3 compliance.

Q: What is the difference between BTB24-800BRG and the Snubberless variants? A: BTB24-800BRG is classified as a Standard TRIAC, while Q8025R6TP, BTA24-800BWRG, and BTB24-800BWRG are Alternistor - Snubberless types. All four parts share identical voltage and current ratings. The triac type designation reflects internal circuit architecture differences.

Q: Are there package differences between Q8025R6TP and the substitute parts? A: Q8025R6TP uses TO-220AB packaging, while all substitute parts use TO-220 packaging. Both are TO-220-3 case styles with through-hole mounting and identical pin configurations, ensuring mechanical compatibility.

Q: Do the lower gate trigger current values in substitute parts affect circuit design? A: BTA24-800BWRG and BTB24-800BWRG feature 50 mA maximum gate trigger current compared to 80 mA for Q8025R6TP. This represents a reduction in gate drive requirements and does not preclude substitution. Circuit designs must accommodate the specified maximum values for each part.

Q: Are all substitute parts currently in production? A: Yes. Q8025R6TP, BTA24-800BWRG, BTB24-800BRG, and BTB24-800BWRG are all active products with confirmed inventory availability.
