TIC216S-S Equivalent & Substitute Parts

Part Overview

The TIC216S-S is a Logic - Sensitive Gate TRIAC rated for 700 V off-state voltage and 6 A on-state current in a TO-220-3 through-hole package, manufactured by Bourns Inc. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the original electrical specifications and mechanical form factor while considering current product availability and status.

Substitute Part Grouping Explanation

Substitution for the TIC216S-S is determined by the following criteria:

Primary Compatibility Parameters:

Voltage - Off State: 700 V (exact match required)
Package / Case: TO-220-3 (mechanical compatibility)
Mounting Type: Through Hole (board assembly compatibility)
Triac Type: Logic - Sensitive Gate (functional equivalence)

Secondary Consideration Parameters:

Current - On State (It (RMS)): Substitute must equal or exceed 6 A
Voltage - Gate Trigger (Vgt): Lower values indicate improved gate sensitivity
Current - Gate Trigger (Igt): Lower values reduce gate drive requirements
Operating Temperature Range: Substitute must cover or exceed -40°C ~ 110°C

Substitute parts are grouped based on adherence to these parameters. Parts meeting all primary criteria are direct substitutes. Parts with higher current ratings or improved gate characteristics provide enhanced performance within the same voltage and package class.

Engineering Selection Recommendations

Direct Substitutes (700 V, Logic - Sensitive Gate, TO-220-3):

ACST1010-7T and ACST1210-7T are direct functional equivalents with 700 V off-state voltage and Logic - Sensitive Gate configuration. Both are manufactured by STMicroelectronics and rated for higher on-state currents (10 A and 12 A respectively) than the TIC216S-S (6 A), providing design margin. ACST1010-7T is currently active in production with 2652 units in stock. ACST1210-7T is obsolete but has 1500 units available. Both feature improved gate trigger voltage (1 V maximum) compared to the TIC216S-S (2.2 V maximum), reducing gate drive requirements.

T410-700T is a Logic - Sensitive Gate TRIAC with 700 V off-state voltage in TO-220-3 package, currently active with 16240 units in stock. However, its 4 A on-state current rating is below the TIC216S-S specification of 6 A and is suitable only for applications with reduced current requirements.

Limited Compatibility (Voltage Mismatch):

BTB16-700SWRG has a 100 V off-state voltage rating, which does not meet the 700 V requirement of the TIC216S-S. This part is not suitable for direct substitution in 700 V applications.

ACST1035-7T Consideration:

ACST1035-7T is a Standard (non-sensitive gate) TRIAC with 700 V off-state voltage and 10 A on-state current. While it meets voltage and package requirements, its Standard gate type differs from the Logic - Sensitive Gate configuration of the TIC216S-S. The gate trigger current specification (35 mA maximum) is significantly higher than the TIC216S-S (5 mA maximum), requiring greater gate drive capability. This part is currently active with 2100 units in stock.

Recommendation Summary:

For direct replacement in existing designs, ACST1010-7T is the preferred substitute, offering active product status, adequate current rating, improved gate sensitivity, and current availability. ACST1210-7T provides higher current capacity for applications requiring additional margin but is obsolete. T410-700T is suitable only for reduced-current applications. ACST1035-7T and BTB16-700SWRG do not meet the primary electrical specifications of the TIC216S-S.

Frequently Asked Questions (FAQ)

Q: Can T410-700T replace TIC216S-S in all applications?

A: No. T410-700T is rated for 4 A on-state current, which is below the TIC216S-S specification of 6 A. It is suitable only for applications with current requirements not exceeding 4 A.

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

A: Logic - Sensitive Gate TRIACs require lower gate trigger current (typically 5-10 mA) and voltage (typically 1-2.2 V) for activation, making them suitable for low-power gate drive circuits. Standard TRIACs require higher gate trigger current (typically 35 mA or higher) and are used in applications with robust gate drive capability. ACST1035-7T is a Standard type and requires higher gate drive than the TIC216S-S.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (T410-700T, ACST1010-7T, ACST1210-7T, ACST1035-7T, and BTB16-700SWRG) are ROHS3 compliant, matching the compliance status of the TIC216S-S.

Q: Why is BTB16-700SWRG listed as a substitute if it has 100 V rating?

A: BTB16-700SWRG does not meet the 700 V off-state voltage requirement of the TIC216S-S and is not a suitable substitute. It is included in the comparison table for reference only.

Q: What is the operating temperature difference between TIC216S-S and substitute parts?

A: The TIC216S-S operates from -40°C to 110°C (TC). All substitute parts operate from -40°C to 125°C (TJ), providing an extended upper temperature range. This difference does not prevent substitution in applications operating within the TIC216S-S temperature range.

Q: Can ACST1035-7T be used as a substitute despite being a Standard type?

A: ACST1035-7T meets the 700 V voltage and TO-220-3 package requirements but differs in gate type and trigger characteristics. It requires higher gate drive current (35 mA maximum versus 5 mA for TIC216S-S). Substitution is possible only if the application circuit can provide the higher gate drive requirement.

Q: Which substitute has the best current availability?

A: T410-700T has the highest inventory with 16240 units in stock. ACST1010-7T has 2652 units available. Both are currently active products. ACST1210-7T (1500 units) and ACST1035-7T (2100 units) are also available but ACST1210-7T is obsolete.
