MAC15-008 TRIAC 600V 15A TO-220AB Equivalent & Substitute Parts

Part Overview

The MAC15-008 is a standard TRIAC rated for 600V off-state voltage and 15A on-state current in a TO-220AB through-hole package, manufactured by onsemi. This part is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility within the specified parameter ranges while meeting current RoHS and REACH compliance standards.

Substitute Part Grouping Explanation

Substitution for the MAC15-008 is determined by the following critical parameters:

Primary Compatibility Criteria:

Voltage - Off State: 600V minimum
Current - On State: 15A or greater
Package / Case: TO-220-3
Mounting Type: Through Hole
Configuration: Single

Secondary Compatibility Criteria:

Voltage - Gate Trigger (Vgt): 2V or lower
Current - Gate Trigger (Igt): 50mA or lower
Current - Hold (Ih): 40mA or lower
Operating Temperature Range: Must include -40°C to 125°C

Substitute parts are grouped into two categories:

Direct Equivalent (Full Current Rating Match): MAC15-8G from Littelfuse Inc. maintains identical electrical specifications and current rating, providing a direct replacement with active product status and improved compliance.

Functional Substitutes (Reduced Current Rating): Parts with lower current ratings (6A, 8A, 12A) can substitute in applications where the full 15A capability is not required. These parts maintain 600V voltage rating and compatible gate trigger characteristics. Selection depends on actual circuit current requirements.

Engineering Selection Recommendations

For Direct Replacement (Recommended): MAC15-8G from Littelfuse Inc. is the primary substitute. It maintains identical electrical specifications to the MAC15-008, operates across the same temperature range, and carries active product status with ROHS3 compliance. This part requires no circuit redesign.

For Current-Limited Applications: When circuit design permits reduced current handling, the following active parts provide substitution:

AVS12CB (12A): Internally triggered TRIAC with active status and ROHS3 compliance. Operating temperature range is 0°C to 125°C; verify compatibility if -40°C operation is required.
BTB08-600BWRG (8A): Alternistor snubberless TRIAC with active status and ROHS3 compliance. Maintains full temperature range.
BTB06-600CWRG (6A): Alternistor snubberless TRIAC with active status and ROHS3 compliance. Maintains full temperature range.

All substitute parts listed are from active manufacturers with current RoHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MAC15-8G directly replace MAC15-008 without circuit modification? A: Yes. MAC15-8G maintains identical voltage rating (600V), current rating (15A), gate trigger specifications, and operating temperature range (-40°C to 125°C). Pin configuration and package are identical TO-220-3. No circuit changes are required.

Q: What is the difference between Standard and Alternistor TRIAC types? A: Standard TRIACs require external snubber networks in some applications. Alternistor (snubberless) TRIACs have integrated snubber characteristics, reducing external component requirements. Both types are electrically compatible when voltage and current ratings match.

Q: Can I use a 12A or 8A TRIAC in place of the 15A MAC15-008? A: Only if your circuit current requirement does not exceed the substitute part's rating. AVS12CB (12A), BTB08-600BWRG (8A), and BTB06-600CWRG (6A) are electrically compatible at 600V. Verify actual circuit current draw before substitution.

Q: Does AVS12CB have a narrower operating temperature range? A: Yes. AVS12CB operates from 0°C to 125°C, compared to MAC15-008's -40°C to 125°C. If your application requires operation below 0°C, use MAC15-8G, BTB08-600BWRG, or BTB06-600CWRG instead.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts carry ROHS3 compliance. The original MAC15-008 is RoHS non-compliant. For new designs and production, use compliant substitutes.

Q: What is the significance of gate trigger voltage (Vgt) differences? A: Lower Vgt values indicate easier gate triggering. MAC15-008 and MAC15-8G specify 2V maximum. Substitutes with 1.3V Vgt trigger more readily. Verify gate drive circuit compatibility; lower Vgt may require circuit adjustment in sensitive applications.

Q: Can I mix different TRIAC types in the same circuit? A: Mixing Standard and Alternistor types is not recommended in the same circuit unless the design explicitly accounts for their different snubber characteristics. Maintain consistency within a single application.
