CQ220-16M SL Equivalent & Substitute Parts

Part Overview

The CQ220-16M SL 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. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute TRIACs must maintain compatibility with the 600 V voltage class and through-hole TO-220-3 mounting while accommodating variations in current rating, gate trigger characteristics, and TRIAC type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CQ220-16M SL is determined by the following criteria:

Mandatory Parameters (Must Match):

• Voltage - Off State: 600 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Flexible Parameters (May Vary):

• Current - On State (It (RMS)): Substitute parts range from 8 A to 12 A, which is lower than the original 16 A rating. Selection depends on circuit current requirements.
• TRIAC Type: Substitutes include Standard, Logic - Sensitive Gate, and Internally Triggered variants. Gate trigger characteristics differ accordingly.
• Voltage - Gate Trigger (Vgt): Ranges from 1.0 V to 1.5 V in substitutes, compared to 2.5 V in the original.
• Current - Gate Trigger (Igt): Ranges from 10 mA to 25 mA in substitutes, compared to 75 mA in the original.

Substitute parts are grouped by current rating and TRIAC type to facilitate selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, ensuring long-term availability and supply chain stability. Selection among substitutes depends on current rating requirements and gate trigger characteristics:

For 8 A applications: BTA08-600CRG (Standard TRIAC), BTA08-600SRG (Logic - Sensitive Gate), L6008R8TP (Logic - Sensitive Gate), or T810H-6T (Logic - Sensitive Gate) are suitable. BTA08-600CRG and BTA08-600SRG are STMicroelectronics products with ROHS3 compliance. L6008R8TP is a Littelfuse product with ROHS3 compliance. T810H-6T is an STMicroelectronics product with extended operating temperature range (-40°C ~ 150°C) and ROHS3 compliance.

For 10 A applications: BTA10-600CRG or T1010H-6T are suitable. BTA10-600CRG is an STMicroelectronics Standard TRIAC with ROHS3 compliance. T1010H-6T is an STMicroelectronics Logic - Sensitive Gate TRIAC with extended operating temperature range (-40°C ~ 150°C) and ROHS3 compliance.

For 12 A applications: BTA212-600E,127 is a WeEn Semiconductors Logic - Sensitive Gate TRIAC with RoHS compliance.

All substitute parts maintain the 600 V voltage rating, TO-220-3 package, and through-hole mounting type. Logic - Sensitive Gate variants feature lower gate trigger voltage (1.0 V to 1.5 V) and current (10 mA) compared to the original internally triggered design (2.5 V, 75 mA), which may require gate drive circuit adjustments.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute TRIAC with a lower current rating than the original CQ220-16M SL?

A: Substitutes with lower current ratings (8 A, 10 A, or 12 A) are suitable only if your circuit current requirements do not exceed the substitute part's maximum on-state current rating. The original 16 A rating cannot be maintained with the available substitutes.

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

A: Standard TRIACs (BTA08-600CRG, BTA10-600CRG) require higher gate trigger current (25 mA) and voltage (1.3 V). Logic - Sensitive Gate variants (BTA08-600SRG, BTA212-600E,127, L6008R8TP, T810H-6T, T1010H-6T) require lower gate trigger current (10 mA) and voltage (1.0 V to 1.5 V), enabling simpler gate drive circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are either ROHS3 Compliant or RoHS Compliant, meeting environmental and regulatory requirements for new designs.

Q: Does the TO-220-3 package remain the same across all substitutes?

A: Yes. All substitute parts use the TO-220-3 through-hole package, ensuring mechanical and electrical compatibility with existing PCB layouts and mounting hardware.

Q: What is the impact of different operating temperature ranges?

A: The original CQ220-16M SL operates from -40°C to 125°C. Some substitutes (T810H-6T, T1010H-6T) extend the upper limit to 150°C, providing additional thermal margin. L6008R8TP operates to 110°C, which is lower than the original. Select based on your application's temperature requirements.

Q: Can I directly replace the CQ220-16M SL with any of these substitutes without circuit modifications?

A: Direct replacement is possible only if the substitute's current rating meets or exceeds your circuit requirements and gate drive characteristics are compatible. Logic - Sensitive Gate variants require lower gate trigger current and voltage, potentially simplifying gate drive circuits compared to the original internally triggered design.
