MAC16CM TRIAC 600V 16A Equivalent & Substitute Parts

Part Overview

The MAC16CM is a standard TRIAC thyristor rated for 600V off-state voltage and 16A on-state current in a TO-220-3 through-hole package. This component is classified as obsolete by the manufacturer (onsemi). Due to its obsolete status, direct equivalents and functional substitutes from active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain the same electrical ratings and mechanical compatibility while offering active product status and improved availability.

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical Ratings): Parts with matching 600V, 16A specifications and identical gate trigger parameters. These include MAC16CMG (onsemi), MAC16HCMG (Littelfuse), and MAC16MG (Littelfuse).

Functional Substitutes (Equivalent or Superior Ratings): Parts with 600V voltage rating and 16A current rating but with different gate trigger characteristics or triac type classification. These include BTA216-600F,127, BTA216-600B,127, BTA216-600B/DG,127, and BTA316-600B,127 from WeEn Semiconductors.

Reduced Current Alternatives (12A Rating): Parts with 600V voltage rating but reduced 12A current rating. These include BTA12-600BWRG and BTB12-600BWRG (STMicroelectronics) and BTB12-600CW3G (Littelfuse). These are suitable only for applications where 12A on-state current is acceptable.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement):

MAC16CMG (onsemi) and MAC16HCMG or MAC16MG (Littelfuse) are direct functional replacements. All three maintain the 600V/16A rating with identical gate trigger voltage specifications. MAC16CMG provides the closest match to the original MAC16CM. MAC16HCMG and MAC16MG offer ROHS3 compliance and active product status, making them suitable for new designs requiring regulatory compliance.

Secondary Substitutes (WeEn Semiconductors BTA/BTA3 Series):

BTA216-600F,127, BTA216-600B,127, BTA216-600B/DG,127, and BTA316-600B,127 all meet the 600V/16A electrical requirements. These parts are RoHS compliant and actively produced. BTA216-600F,127 features lower gate trigger current (25mA) and hold current (30mA) compared to the original specification. BTA216-600B,127, BTA216-600B/DG,127, and BTA316-600B,127 feature higher gate trigger current (50mA) and hold current (60mA), which may require circuit evaluation in sensitive gate drive applications.

Reduced Current Alternatives (12A Rating):

BTA12-600BWRG, BTB12-600BWRG, and BTB12-600CW3G are suitable only for applications where the 12A on-state current rating is acceptable. These parts are not direct replacements for 16A applications but may be used in designs with lower current requirements. All three are RoHS compliant and actively produced.

Frequently Asked Questions (FAQ)

Q: Can MAC16CMG be used as a direct replacement for MAC16CM?

A: Yes. MAC16CMG is manufactured by onsemi and maintains identical electrical specifications: 600V off-state voltage, 16A on-state current, 1.5V maximum gate trigger voltage, and TO-220-3 package. The primary difference is product status; MAC16CMG is active while MAC16CM is obsolete.

Q: What is the difference between MAC16HCMG and MAC16MG?

A: Both are manufactured by Littelfuse Inc. and share identical electrical ratings (600V, 16A, 1.5V Vgt). Both are ROHS3 compliant and actively produced. The difference lies in packaging: MAC16HCMG is supplied in Box packaging while MAC16MG is also supplied in Box packaging. Both are suitable for new designs.

Q: Can BTA216-600F,127 replace MAC16CM in all applications?

A: BTA216-600F,127 meets the 600V/16A electrical requirements and TO-220-3 package specification. However, it features lower gate trigger current (25mA vs. 35mA) and lower hold current (30mA vs. 50mA). Circuit evaluation is necessary to confirm compatibility with existing gate drive circuits.

Q: Are the 12A rated parts (BTA12-600BWRG, BTB12-600BWRG, BTB12-600CW3G) suitable replacements?

A: These parts are not direct replacements for 16A applications. They are suitable only for applications where the on-state current requirement is 12A or less. The 600V voltage rating and TO-220-3 package are compatible, but the reduced current rating must be verified against application requirements.

Q: What is the difference between BTA216 and BTA316 series?

A: Both BTA216-600B,127 and BTA316-600B,127 meet the 600V/16A specification with identical gate trigger parameters. The primary difference is the base product number designation. Both are RoHS compliant and actively produced by WeEn Semiconductors.

Q: Do all substitute parts have the same operating temperature range?

A: Most substitute parts maintain the -40°C to 125°C operating temperature range. BTA216-600F,127, BTA216-600B,127, BTA216-600B/DG,127, and BTA316-600B,127 specify 125°C maximum junction temperature without explicit minimum temperature specification in the provided data. Confirm full temperature range requirements with the manufacturer datasheet for critical applications.

Q: Are all substitute parts RoHS compliant?

A: MAC16CMG does not specify RoHS status. MAC16HCMG and MAC16MG are ROHS3 compliant. BTA216-600F,127, BTA216-600B,127, BTA216-600B/DG,127, and BTA316-600B,127 are RoHS compliant. BTA12-600BWRG, BTB12-600BWRG, and BTB12-600CW3G are ROHS3 compliant. Verify compliance requirements for your application.
