Substitute Part Grouping Explanation

Substitution of the Q6016RH6TP is determined by the following critical parameters:

Voltage - Off State: 600 V (exact match required)
Current - On State (It (RMS)) (Max): 16 A (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: TO-220-3 (exact match required)
Operating Temperature Range: -40°C ~ 125°C (TJ) (exact match required)
RoHS Status: ROHS3 Compliant (compliance maintained)

Substitute parts are grouped into two categories based on TRIAC type: Alternistor - Snubberless variants (functionally equivalent to the main part) and Standard TRIAC variants (electrically compatible with different gate trigger characteristics). Parts with 15 A or 25 A current ratings are listed as extended alternatives where current derating is acceptable for the application.

Engineering Selection Recommendations

Direct substitutes for the Q6016RH6TP maintain 600 V off-state voltage, 16 A on-state current, TO-220-3 package, and -40°C to 125°C operating temperature range. All listed parts are Active product status and RoHS3 compliant.

BTB16-600BWRG (STMicroelectronics) and BTB16-600CWRG (STMicroelectronics) are Alternistor - Snubberless variants matching the main part's TRIAC type classification. BTB16-600BW3G (Littelfuse Inc.), MAC16HCMG (Littelfuse Inc.), BTB16-600BRG (STMicroelectronics), BTB16-600CRG (STMicroelectronics), and BTB16-600SWRG (STMicroelectronics) are Standard or Logic - Sensitive Gate TRIAC variants with identical voltage and current ratings but different gate trigger characteristics.

MAC15A8G (Littelfuse Inc.) and MAC15MG (onsemi) provide 15 A on-state current at 600 V, suitable for applications where current derating below 16 A is acceptable. BTB24-600BRG (STMicroelectronics) provides 25 A on-state current at 600 V for applications requiring higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Q6016RH6TP with a 15 A TRIAC?

A: MAC15A8G and MAC15MG are electrically compatible at 600 V but rated for 15 A maximum on-state current. Substitution is valid only if the application current requirement does not exceed 15 A RMS.

Q: What is the difference between Alternistor - Snubberless and Standard TRIAC types?

A: Alternistor - Snubberless TRIACs (Q6016RH6TP, BTB16-600BWRG, BTB16-600CWRG) are designed for snubberless operation. Standard TRIACs (BTB16-600BW3G, MAC16HCMG, BTB16-600BRG, BTB16-600CRG) and Logic - Sensitive Gate TRIACs (BTB16-600SWRG) have different gate trigger and hold current specifications. Selection depends on circuit snubber requirements and gate drive capabilities.

Q: Are all substitute parts available in the same package?

A: All listed substitute parts use the TO-220-3 package with Through Hole mounting. Physical dimensions and pin configurations are compatible with the Q6016RH6TP.

Q: What does RoHS3 compliance mean?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. All listed parts maintain ROHS3 Compliant status.

Q: Can I use BTB16-600SWRG as a direct replacement?

A: BTB16-600SWRG is a Logic - Sensitive Gate TRIAC with 10 mA maximum gate trigger current, lower than the Q6016RH6TP's 80 mA. It is electrically compatible at 600 V and 16 A but requires gate drive circuit adjustment for the reduced trigger current specification.

Q: What is the difference between BTB16-600CRG and BTB16-600CWRG?

A: BTB16-600CRG is a Standard TRIAC with 25 mA maximum gate trigger current and 25 mA hold current. BTB16-600CWRG is an Alternistor - Snubberless variant with 35 mA maximum gate trigger current and 35 mA hold current. Both are 600 V, 16 A devices in TO-220-3 packages.
