MAC16HCN TRIAC 800V 16A Equivalent & Substitute Parts

Part Overview

The MAC16HCN is a standard TRIAC thyristor rated for 800V 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 manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain the same electrical specifications and package form factor while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the MAC16HCN are classified into two categories based on electrical parameter compatibility:

Direct Equivalents (16A Rating): Parts maintaining identical on-state current rating of 16A with matching voltage, gate trigger, and hold current specifications. These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Alternatives (12A Rating): Parts with reduced on-state current rating of 12A but matching 800V voltage rating and compatible gate trigger characteristics. These parts are suitable for applications where the 16A current capacity is not fully utilized and can operate within the same voltage and thermal environment.

Key Parameters Determining Substitution:

Voltage - Off State: 800V (fixed requirement)
Current - On State (It (RMS)): 16A (direct equivalents) or 12A (similar alternatives)
Package / Case: TO-220-3 (all substitutes)
Mounting Type: Through Hole (all substitutes)
Gate Trigger Voltage (Vgt): 1.0V to 1.5V range (compatible)
Operating Temperature: -40°C to 125°C or higher (compatible)

Frequently Asked Questions (FAQ)

Q: Can MAC16HCNG be used as a direct replacement for MAC16HCN?

A: Yes. MAC16HCNG maintains identical electrical specifications including 800V off-state voltage, 16A on-state current, 1.5V maximum gate trigger voltage, and -40°C to 125°C operating temperature range. The part is pin-compatible in TO-220-3 package and requires no circuit modification.

Q: What is the difference between direct equivalents and similar alternatives?

A: Direct equivalents (MAC16HCNG, MAC16NG, BTA316 series, BTA216-800B,127) maintain the 16A on-state current rating of the original MAC16HCN. Similar alternatives (ACTT12 series, BTA12 series, BTB12-800BW3G) have reduced 12A on-state current rating. Selection depends on whether the application requires the full 16A capacity or can operate at 12A.

Q: Are all substitute parts RoHS compliant?

A: Most substitute parts are RoHS or ROHS3 compliant. The original MAC16HCN is RoHS non-compliant. Littelfuse MAC16HCNG and MAC16NG are ROHS3 compliant. WeEn Semiconductors BTA316-800B,127 is ROHS3 compliant; BTA316-800B0,127 and BTA216-800B,127 are RoHS compliant. STMicroelectronics BTA12 series parts are ROHS3 compliant. onsemi BTB12-800BW3G compliance status is not specified in available data.

Q: What is the operating temperature difference between substitute parts?

A: The original MAC16HCN and most 16A equivalents (MAC16HCNG, MAC16NG, BTA12 series, BTB12-800BW3G) operate from -40°C to 125°C. WeEn Semiconductors 16A parts (BTA316 series, BTA216-800B,127) and 12A parts (ACTT12-800CQ, ACTT12-800CTQ) are specified at 125°C (TJ) maximum. ACTT12-800CTQ extends to 150°C (TJ). Applications requiring full -40°C to 125°C range should select parts explicitly rated for this temperature span.

Q: What packaging options are available for substitute parts?

A: MAC16HCNG is supplied in tube packaging. MAC16NG is supplied in box packaging. BTA316 series, BTA216-800B,127, ACTT12 series, and BTA12 series are supplied in tube packaging. BTB12-800BW3G is supplied in bulk packaging. All parts use TO-220-3 through-hole package form factor.

Q: Can BTA12-800BWRG (Alternistor - Snubberless) be used in place of standard TRIAC types?

A: BTA12-800BWRG is classified as an Alternistor - Snubberless type, distinct from standard TRIAC classification. While it maintains the same 800V voltage rating, 12A current rating, and TO-220-3 package, the snubberless design may affect circuit behavior. Applications currently using standard TRIAC types should evaluate snubberless characteristics before substitution.

Q: What inventory levels are available for each substitute part?

A: MAC16HCNG has 2,200 units in stock. MAC16NG has 1,296 units. BTA316-800B,127 has 22,100 units. BTA316-800B0,127 has 1,124 units. BTA216-800B,127 has 1,047 units. ACTT12-800CQ has 1,005 units.
