Substitute Part Grouping Explanation

Substitution eligibility for the ACTT10-800CTNQ is determined by the following criteria:

Mandatory Matching Parameters:

Voltage - Off State: 800V (exact match required)
Package / Case: TO-220-3 (mechanical compatibility)
Mounting Type: Through Hole (assembly compatibility)
Configuration: Single (functional equivalence)

Allowable Parameter Ranges for Substitution:

Current - On State (It (RMS)): 10A or greater
Voltage - Gate Trigger (Vgt): 1V or less
Current - Gate Trigger (Igt): 35mA or less
Current - Hold (Ih): 30mA or less
Current - Non Rep. Surge: 90A or greater (50Hz), 99A or greater (60Hz)
Operating Temperature: 150°C or greater

Substitute parts meeting these criteria maintain functional compatibility while allowing for component availability and supply chain flexibility.

Engineering Selection Recommendations

Direct Current Rating Match (BTA10-800CWRG): The BTA10-800CWRG from STMicroelectronics matches the 10A on-state current rating of the ACTT10-800CTNQ. This part is ROHS3 compliant and actively produced. The Alternistor - Snubberless type provides enhanced performance characteristics for AC switching applications. Operating temperature range is -40°C to 125°C.

Lower Current Rating Substitutes (ACST830-8T, BTA08-800CW3G, Q8008RH4TP): These parts are rated for 8A on-state current, below the 10A specification of the main part. Substitution is valid only when application current requirements do not exceed 8A. ACST830-8T and Q8008RH4TP are ROHS3 compliant. BTA08-800CW3G compliance status is not specified. All are actively produced.

Higher Current Rating Substitute (MAC12NG): The MAC12NG from Littelfuse Inc. is rated for 12A on-state current, exceeding the 10A requirement. This part is ROHS3 compliant and actively produced. Gate trigger voltage is 1.5V, which is higher than the main part specification of 1V maximum.

Compliance and Availability: All substitute parts maintain 800V off-state voltage and TO-220-3 package compatibility. ROHS3 compliance is confirmed for ACST830-8T, BTA10-800CWRG, MAC12NG, and Q8008RH4TP. All parts are actively produced with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ACST830-8T replace ACTT10-800CTNQ in all applications? A: ACST830-8T is suitable only for applications where the maximum on-state current requirement does not exceed 8A. The main part is rated for 10A. Verify application current specifications before substitution.

Q: What is the difference between Standard and Alternistor - Snubberless TRIAC types? A: Both types are 800V rated thyristors in TO-220-3 packages. Alternistor - Snubberless types (BTA10-800CWRG, Q8008RH4TP) have different internal characteristics. Selection depends on specific application requirements and circuit design.

Q: Is BTA10-800CWRG a direct replacement for ACTT10-800CTNQ? A: BTA10-800CWRG matches the 10A current rating and 800V voltage specification. Both use TO-220-3 packages. BTA10-800CWRG is ROHS3 compliant and actively produced. Verify gate trigger voltage requirements, as BTA10-800CWRG specifies 1.3V maximum versus 1V for the main part.

Q: Why does MAC12NG have a higher current rating than the main part? A: MAC12NG is rated for 12A on-state current, which exceeds the 10A requirement. This part is suitable for applications requiring higher current capacity within the same 800V voltage class and TO-220-3 package.

Q: Are all substitute parts RoHS compliant? A: ACST830-8T, BTA10-800CWRG, MAC12NG, and Q8008RH4TP are ROHS3 compliant. BTA08-800CW3G compliance status is not specified in available documentation.

Q: What is the operating temperature range difference between the main part and substitutes? A: ACTT10-800CTNQ is rated to 150°C junction temperature. All listed substitutes are rated for -40°C to 125°C operating range. Verify thermal requirements for applications operating above 125°C.

Q: Can I use Q8008RH4TP in place of ACTT10-800CTNQ? A: Q8008RH4TP is rated for 8A on-state current, below the 10A specification. Substitution is valid only when application current does not exceed 8A. Q8008RH4TP uses a non-isolated tab TO-220 package variant; verify mechanical compatibility with your PCB layout.
