CQ220-16M TRIAC Equivalent & Substitute Parts

Part Overview

The CQ220-16M is an internally triggered TRIAC rated for 600 V off-state voltage and 16 A on-state current in a TO-220-3 through-hole package. Manufactured by Central Semiconductor Corp, this component is classified as obsolete. Due to its obsolete status and limited availability, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the CQ220-16M is determined by the following critical parameters:

Voltage Rating: All substitutes must maintain 600 V off-state voltage to ensure circuit protection and reliability.
Current Rating: Substitutes must support at least 16 A on-state current to handle the same load requirements.
Package Type: TO-220-3 through-hole package is mandatory for mechanical and thermal compatibility.
Operating Temperature Range: Substitutes must support the -40°C to 125°C operating range or higher.
Gate Trigger Characteristics: Vgt and Igt parameters determine gate drive circuit compatibility.

The substitute parts listed below meet these core requirements while offering active product status and improved availability from established manufacturers including STMicroelectronics, WeEn Semiconductors, and Littelfuse Inc.

Engineering Selection Recommendations

Primary Substitute: MAC16MG (Littelfuse Inc.)

The MAC16MG provides the closest electrical match to the CQ220-16M with identical 16 A current rating and 600 V voltage rating. This part maintains the same operating temperature range (-40°C to 125°C) and is ROHS3 compliant. Active product status ensures long-term availability and supply chain stability.

Secondary Substitutes for Reduced Current Applications:

T1225T-6I (STMicroelectronics): 12 A rating, Alternistor type, ROHS3 compliant, active status. Suitable for applications requiring 12 A or less.
BTA212-600E,127 (WeEn Semiconductors): 12 A rating, Logic - Sensitive Gate type, RoHS compliant, active status. Lower gate trigger current (10 mA) reduces gate drive requirements.
BTA10-600CRG (STMicroelectronics): 10 A rating, Standard type, ROHS3 compliant, active status. For applications requiring 10 A or less.
BTA08-600CRG (STMicroelectronics): 8 A rating, Standard type, ROHS3 compliant, active status. For applications requiring 8 A or less.

All substitute parts share the TO-220-3 through-hole package, 600 V voltage rating, and -40°C to 125°C operating temperature range with the original part. Selection should be based on actual circuit current requirements and gate drive circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAC16MG directly replace CQ220-16M in all applications?

A: MAC16MG matches the 16 A current rating and 600 V voltage rating of CQ220-16M and shares the same TO-220-3 package. However, gate trigger voltage (Vgt) is lower at 1.5 V versus 2.5 V, and gate trigger current (Igt) is lower at 50 mA versus 75 mA. Verify that your gate drive circuit can operate within these specifications before substitution.

Q: What is the difference between Standard, Logic - Sensitive Gate, and Alternistor TRIAC types?

A: Standard TRIACs require higher gate trigger current. Logic - Sensitive Gate types require lower gate trigger current (10 mA), reducing gate drive circuit complexity. Alternistor types are snubberless designs optimized for inductive loads. Selection depends on your specific application requirements and gate drive capabilities.

Q: Can I use a lower current-rated substitute like BTA08-600CRG?

A: Lower current-rated substitutes are only suitable if your application requires less than their rated current. For example, BTA08-600CRG (8 A) can replace CQ220-16M only in circuits drawing 8 A or less. Using an undersized TRIAC in a higher-current application will cause thermal stress and failure.

Q: Are all substitute parts RoHS compliant?

A: Yes. MAC16MG, T1225T-6I, BTA212-600E,127, BTA10-600CRG, and BTA08-600CRG are all RoHS compliant (ROHS3 or RoHS Compliant status), meeting environmental and regulatory requirements for new designs.

Q: What is the significance of the TO-220-3 package?

A: TO-220-3 is a through-hole package with three leads (Gate, MT1, MT2) that provides mechanical compatibility with existing PCB layouts and thermal management through direct board contact. All listed substitutes use this same package, ensuring drop-in compatibility without PCB redesign.

Q: How do gate trigger parameters (Vgt and Igt) affect circuit design?

A: Vgt (Gate Trigger Voltage) and Igt (Gate Trigger Current) determine the minimum gate drive signal required to turn on the TRIAC. Lower values reduce gate drive circuit complexity and power consumption. Verify your gate drive circuit can supply the required voltage and current for your selected substitute part.
