MAC16D TRIAC 400V 16A Equivalent & Substitute Parts

Part Overview

The MAC16D is a standard TRIAC rated for 400V off-state voltage and 16A on-state current in a TO-220-3 through-hole package. Manufactured by onsemi, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain the same electrical performance envelope while offering active manufacturing status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Equivalents maintain all electrical parameters within the specified limits:

Voltage - Off State: 400 V
Current - On State (It (RMS)) (Max): 16 A
Voltage - Gate Trigger (Vgt) (Max): ≤ 1.5 V
Current - Gate Trigger (Igt) (Max): ≤ 50 mA
Current - Hold (Ih) (Max): ≤ 50 mA
Operating Temperature: -40°C ~ 125°C (TJ)
Package / Case: TO-220-3
Mounting Type: Through Hole

Similar Substitutes meet the core functional requirements but differ in one or more parameters:

Voltage - Off State may exceed 400 V (higher voltage rating provides backward compatibility)
Current - On State (It (RMS)) (Max) remains at 16 A minimum
Gate trigger characteristics remain within acceptable ranges
Package and mounting type remain TO-220-3 through-hole

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Choices):

MAC16DG and MAC16HCDG are direct electrical and mechanical equivalents manufactured by onsemi. Both parts maintain identical electrical specifications to the MAC16D while offering active product status. MAC16DG is available in bulk packaging with 9,073 units in stock. MAC16HCDG is available in bulk packaging with 3,133 units in stock. Both are RoHS non-compliant, matching the original part's compliance status.

Higher Voltage Rated Substitutes (Backward Compatible):

BTA216-600B,127 (WeEn Semiconductors) and BTB16-600BWRG (STMicroelectronics) are rated for 600V off-state voltage while maintaining 16A on-state current. These parts are electrically compatible in applications where the MAC16D operates below 400V. BTA216-600B,127 is RoHS compliant. BTB16-600BWRG is ROHS3 compliant and features Snubberless™ technology, offering enhanced performance characteristics. Both maintain TO-220-3 through-hole packaging.

Current-Limited Substitute (Derating Required):

Q4010R5TP (Littelfuse Inc.) is rated for 400V off-state voltage but limited to 10A on-state current. This part is suitable only for applications where the load current does not exceed 10A. ROHS3 compliant. Maintains TO-220-3 through-hole packaging and -40°C ~ 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can MAC16DG directly replace MAC16D?

A: Yes. MAC16DG is a direct equivalent with identical electrical parameters: 400V off-state voltage, 16A on-state current, 1.5V maximum gate trigger voltage, and 50mA maximum gate trigger current. Both use TO-220-3 through-hole packaging. MAC16DG is manufactured by onsemi and maintains active product status.

Q: What is the difference between MAC16DG and MAC16HCDG?

A: Both parts are direct equivalents with identical electrical specifications and TO-220-3 packaging. The difference lies in manufacturing date codes and internal construction variants. Both are suitable for direct substitution of MAC16D.

Q: Can I use BTA216-600B,127 or BTB16-600BWRG in place of MAC16D?

A: Yes, with design considerations. Both parts maintain 16A on-state current and TO-220-3 packaging. The 600V off-state voltage rating is higher than the MAC16D's 400V rating, making these parts suitable for applications operating below 400V. BTA216-600B,127 has a maximum hold current of 60mA compared to MAC16D's 50mA. BTB16-600BWRG features lower gate trigger voltage (1.3V vs. 1.5V) and Snubberless™ technology.

Q: Is Q4010R5TP a suitable replacement for MAC16D?

A: Q4010R5TP is suitable only for applications where on-state current does not exceed 10A. The part is rated for 400V off-state voltage, matching MAC16D, but its 10A current rating is below the MAC16D's 16A specification. Use only when load current requirements are confirmed below 10A.

Q: What packaging options are available for these substitutes?

A: All substitute parts listed maintain TO-220-3 through-hole packaging, identical to MAC16D. Packaging variants (bulk, tube) affect procurement and handling but do not affect electrical or mechanical compatibility.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. MAC16D, MAC16DG, and MAC16HCDG are RoHS non-compliant. BTA216-600B,127 is RoHS compliant. BTB16-600BWRG is ROHS3 compliant. Q4010R5TP is ROHS3 compliant. Select based on your application's compliance requirements.
