Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QJ8016RH3TP is determined by strict alignment of the following critical parameters:

• Voltage - Off State: 800 V (exact match required)
• Current - On State (It (RMS)) (Max): 16 A (exact match required)
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V (exact match required)
• Current - Hold (Ih) (Max): 35 mA (exact match required)
• Package / Case: TO-220-3 (exact match required)
• Mounting Type: Through Hole (exact match required)
• Triac Type: Alternistor - Snubberless (exact match required)

The BTA16-800CWRG meets all substitution criteria within the defined electrical and mechanical parameter set for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the QJ8016RH3TP and BTA16-800CWRG maintain Active product status and full regulatory compliance under RoHS3 and REACH standards. Selection between these parts is based on availability and supply chain requirements rather than functional differences. The BTA16-800CWRG exhibits slightly lower maximum operating temperature (125°C vs. 150°C junction temperature) and reduced non-repetitive surge current ratings, which remain within acceptable tolerance for standard AC switching applications. Both components are suitable for direct substitution in TO-220AB through-hole mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the BTA16-800CWRG replace the QJ8016RH3TP in existing designs?

A: Yes. Both parts share identical voltage, current, and gate trigger specifications. The TO-220-3 package footprint is mechanically compatible. The BTA16-800CWRG operates within acceptable parameter tolerances for applications designed around the QJ8016RH3TP.

Q: What is the difference in operating temperature range between these parts?

A: The QJ8016RH3TP operates from -40°C to 150°C junction temperature, while the BTA16-800CWRG operates from -40°C to 125°C. For applications requiring sustained operation above 125°C, the QJ8016RH3TP is the appropriate selection.

Q: Are the non-repetitive surge current ratings equivalent?

A: The QJ8016RH3TP is rated for 167 A (50 Hz) and 200 A (60 Hz) surge current. The BTA16-800CWRG is rated for 160 A (50 Hz) and 168 A (60 Hz). Both ratings support standard AC switching applications. Applications requiring maximum surge protection should reference the specific surge current specification.

Q: Do both parts require identical PCB layout and thermal management?

A: Both parts use the TO-220-3 package with identical lead spacing and thermal pad configuration. PCB layout and heatsinking requirements remain unchanged during substitution.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS3 compliant and REACH unaffected. No compliance differences exist between the two components.
