CQDD-16M BK TRIAC Equivalent & Substitute Parts

Part Overview

The CQDD-16M BK is a Logic-Sensitive Gate TRIAC rated for 600 V off-state voltage and 16 A on-state current in a D2PAK surface mount package, manufactured by Central Semiconductor Corp. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute parts are selected based on matching electrical characteristics (voltage rating, current capacity, gate trigger parameters) and mechanical compatibility (D2PAK package, surface mount configuration). The substitution logic accommodates variations in current ratings and gate trigger specifications within acceptable operational ranges for this product category.

Substitute Part Grouping Explanation

Substitute parts are organized into two functional categories based on electrical characteristics:

Category 1: Logic-Sensitive Gate TRIACs with Reduced Current Ratings (8 A - 12 A) These parts maintain the sensitive gate architecture and 600 V voltage rating but operate at lower on-state current levels. Substitution is valid for applications where the 16 A rating of the original part exceeds system requirements. Parts in this category include BTA212B-600E,118 (12 A), T1010H-6G (10 A), T810H-6G (8 A), and T810H-6G-TR (8 A).

Category 2: Standard TRIAC with Full Current Rating (16 A) BTA216B-600F,118 matches the 16 A on-state current rating but uses standard gate architecture rather than sensitive gate. This part is suitable for applications where gate trigger sensitivity is not a critical design parameter.

Key Parameters Determining Substitution:

• Voltage - Off State: 600 V (all substitutes match)
• Package / Case: D2PAK surface mount (all substitutes match)
• Current - On State (It RMS Max): 16 A (BTA216B-600F,118 matches; others reduced)
• TRIAC Type: Logic-Sensitive Gate preferred; Standard acceptable if gate sensitivity not required
• Product Status: Active (all substitutes are active products)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (16 A Current Requirement): BTA216B-600F,118 provides the closest electrical match with identical 16 A on-state current rating and D2PAK package. This part is manufactured by WeEn Semiconductors and holds active product status with RoHS compliance. The primary difference is TRIAC type classification (Standard vs. Logic-Sensitive Gate); this substitution is valid when gate trigger sensitivity is not a design constraint.

For Sensitive Gate Architecture Preservation: BTA212B-600E,118 maintains Logic-Sensitive Gate architecture with 12 A on-state current rating. This part is suitable for applications where the original 16 A rating provides design margin and sensitive gate characteristics are required. WeEn Semiconductors manufactures this part with active product status and RoHS compliance.

For Extended Temperature Range: T1010H-6G and T810H-6G (both STMicroelectronics) offer operating temperature ranges extending to 150°C, compared to 125°C for the original part. T1010H-6G provides 10 A current capacity while T810H-6G provides 8 A. Both maintain Logic-Sensitive Gate architecture, ROHS3 compliance, and active product status. These parts are suitable for applications requiring higher temperature operation with reduced current requirements.

For Tape & Reel Packaging: T810H-6G-TR is the tape and reel variant of T810H-6G, providing identical electrical specifications with alternative packaging for automated assembly processes. This part is manufactured by STMicroelectronics with ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can BTA216B-600F,118 replace CQDD-16M BK in all applications? A: BTA216B-600F,118 matches the 16 A current rating and 600 V voltage specification with identical D2PAK packaging. The difference is TRIAC type: BTA216B-600F,118 is classified as Standard while CQDD-16M BK is Logic-Sensitive Gate. Substitution is valid if gate trigger sensitivity is not a critical design requirement. Verify gate drive circuit compatibility before implementation.

Q: What is the difference between Logic-Sensitive Gate and Standard TRIAC types? A: Logic-Sensitive Gate TRIACs have lower gate trigger current requirements (typically 10 mA maximum) compared to Standard types (25 mA maximum). Logic-Sensitive Gate architecture is advantageous in applications with limited gate drive capability. Standard TRIACs provide broader gate trigger voltage tolerance. Selection depends on gate drive circuit design.

Q: Can I use T810H-6G (8 A) instead of CQDD-16M BK (16 A)? A: T810H-6G is suitable only if your application requires maximum on-state current of 8 A or less. This part maintains Logic-Sensitive Gate architecture and extends operating temperature to 150°C. Verify that 8 A current capacity meets system load requirements before substitution.

Q: What is the significance of the D2PAK package specification? A: D2PAK (TO-263-3) is a surface mount package with 2 leads plus a tab for thermal connection. All substitute parts use identical D2PAK packaging, ensuring mechanical and thermal compatibility with existing PCB layouts and thermal management designs. No package redesign is required.

Q: Are all substitute parts RoHS compliant? A: Yes. BTA212B-600E,118 and BTA216B-600F,118 are RoHS Compliant. T1010H-6G, T810H-6G, and T810H-6G-TR are ROHS3 Compliant. All substitute parts meet current RoHS requirements.

Q: What is the difference between T810H-6G and T810H-6G-TR? A: Both parts have identical electrical specifications and are manufactured by STMicroelectronics. The difference is packaging: T810H-6G is supplied in Tube packaging while T810H-6G-TR is supplied in Tape & Reel (TR) packaging. Tape & Reel packaging is optimized for automated assembly processes.

Q: Can I use BTA212B-600E,118 (12 A) if my application requires 16 A? A: No. BTA212B-600E,118 has a maximum on-state current rating of 12 A. Using this part in an application requiring 16 A would exceed the component's rated capacity and create reliability risk. Use only if your actual system current requirement is 12 A or less.
