CQ220-12M SL Equivalent & Substitute Parts

Part Overview

The CQ220-12M SL is an internally triggered TRIAC rated for 600 V off-state voltage and 12 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 ongoing design support and production continuity. Substitute parts are selected based on matching or exceeding the electrical performance parameters while maintaining compatible packaging and thermal characteristics.

Substitute Part Grouping Explanation

Substitution for the CQ220-12M SL is determined by the following criteria:

Primary Matching Parameters:

Voltage - Off State: 600 V (required)
Current - On State: 12 A or greater (required)
Package / Case: TO-220-3 (required for mechanical compatibility)
Mounting Type: Through Hole (required)

Secondary Compatibility Parameters:

Voltage - Gate Trigger (Vgt): Lower or equal values are acceptable
Current - Gate Trigger (Igt): Lower or equal values are acceptable
Current - Hold (Ih): Equal or lower values are acceptable
Operating Temperature Range: Must encompass the original -40°C to 125°C minimum

Substitute parts are grouped by TRIAC type (Standard, Logic - Sensitive Gate, or Alternistor - Snubberless) and current rating. Parts meeting or exceeding the 12 A requirement at 600 V are direct substitutes. Parts with lower current ratings (8 A or 10 A) are listed as alternatives for applications where reduced current capacity is acceptable.

Engineering Selection Recommendations

Direct Substitutes (12 A Rating):

BTA212-600E,127 and T1225T-6I are the primary direct substitutes for the CQ220-12M SL, both rated at 12 A and 600 V. BTA212-600E,127 is a Logic - Sensitive Gate TRIAC from WeEn Semiconductors with active product status and RoHS compliance. T1225T-6I is an Alternistor - Snubberless TRIAC from STMicroelectronics with ROHS3 compliance and extended temperature range to 150°C. Both maintain TO-220-3 through-hole packaging and are suitable for direct replacement in applications requiring 12 A current capacity.

Alternative Substitutes (10 A Rating):

BTA10-600CRG and T1010H-6T are rated at 10 A and 600 V. These parts are suitable for applications where the load current does not exceed 10 A. T1010H-6T offers an extended operating temperature range to 150°C and lower gate trigger voltage (1 V maximum). Both are ROHS3 compliant and active products from STMicroelectronics.

Alternative Substitutes (8 A Rating):

BTA08-600CRG, BTA08-600SRG, BTB08-600CRG, and T810H-6T are rated at 8 A and 600 V. These parts are suitable only for applications where the load current does not exceed 8 A. BTA08-600SRG and T810H-6T feature Logic - Sensitive Gate characteristics with lower gate trigger current (10 mA maximum). T810H-6T offers extended temperature range to 150°C. All are ROHS3 compliant and active products.

All substitute parts maintain the required 600 V off-state voltage, TO-220-3 package, and through-hole mounting. Selection should be based on the specific current requirement of the application and compliance certifications needed for the end product.

Frequently Asked Questions (FAQ)

Q: Can BTA08-600CRG replace CQ220-12M SL in all applications?

A: BTA08-600CRG is rated at 8 A maximum on-state current, compared to the CQ220-12M SL at 12 A. It is suitable only for applications where the load current does not exceed 8 A. If the application requires 12 A capacity, use BTA212-600E,127 or T1225T-6I instead.

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

A: These are different TRIAC architectures. Standard TRIACs (BTA08-600CRG, BTA10-600CRG) have higher gate trigger current requirements (25 mA). Logic - Sensitive Gate TRIACs (BTA08-600SRG, BTA212-600E,127, T1010H-6T, T810H-6T) have lower gate trigger current (10 mA) and lower gate trigger voltage (1 V to 1.3 V), making them suitable for logic-level control circuits. Alternistor - Snubberless TRIACs (T1225T-6I) are optimized for applications without external snubber networks. Selection depends on the gate drive circuit design.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are either RoHS Compliant or ROHS3 Compliant. The original CQ220-12M SL RoHS status is not specified in the available data.

Q: Can I use a substitute part with a lower operating temperature range?

A: The CQ220-12M SL operates from -40°C to 125°C. All substitute parts listed meet or exceed this temperature range. BTA212-600E,127 specifies only 125°C maximum junction temperature without a minimum, which may limit use in low-temperature environments. T1010H-6T and T810H-6T extend the upper temperature limit to 150°C, providing additional thermal margin.

Q: Is the TO-220-3 package compatible across all substitute parts?

A: Yes. All substitute parts use TO-220-3 through-hole packaging, ensuring mechanical and thermal compatibility with the original CQ220-12M SL. Some parts specify TO-220AB or TO-220AB Insulated variants, which are compatible with standard TO-220-3 footprints.

Q: What is the significance of lower gate trigger voltage in substitute parts?

A: The CQ220-12M SL has a maximum gate trigger voltage of 2.5 V. Substitute parts with lower Vgt values (1 V to 1.5 V) require less gate voltage to trigger conduction. This is beneficial for logic-level gate drive circuits but requires verification that the gate drive circuit can provide adequate current at the lower voltage threshold.
