S2016R Equivalent & Substitute Parts

Part Overview

The S2016R is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc., rated for 200V off-state voltage and 16A RMS on-state current in a TO-220-3 through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The S2016R operates across a temperature range of -40°C to 125°C and is ROHS3 compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S2016R is determined by the following critical parameters:

• Package Compatibility: TO-220-3 through-hole mounting
• Current Rating: 16A RMS on-state current (It (RMS))
• Gate Trigger Characteristics: Vgt (Max) 1.5V and Igt (Max) ≤ 30mA
• On-State Voltage: Vtm (Max) 1.6V
• Hold Current: Ih (Max) 40mA
• Operating Temperature Range: -40°C to 125°C
• Compliance: ROHS3 compliant

The TYN616RG from STMicroelectronics meets all substitution criteria. While the TYN616RG features a higher off-state voltage rating (600V versus 200V), this represents an uprating that maintains full backward compatibility. All gate trigger parameters, on-state characteristics, hold current, and thermal operating range are equivalent or superior to the S2016R specification.

Engineering Selection Recommendations

The TYN616RG is the direct substitute for the S2016R. Selection is based on the following factors:

• Product Status: The S2016R is obsolete; the TYN616RG is active and in production with 28,500 units in stock.
• Compliance Alignment: Both components are ROHS3 compliant, maintaining regulatory consistency.
• Electrical Equivalence: Gate trigger voltage, on-state voltage, and hold current specifications are identical. Gate trigger current is lower in the TYN616RG (25mA versus 30mA), representing improved performance.
• Voltage Uprating: The 600V off-state rating of the TYN616RG provides enhanced voltage margin compared to the 200V rating of the S2016R, with no negative impact on circuit operation in 200V applications.
• Thermal Compatibility: Identical operating temperature range ensures thermal performance equivalence.
• Package Compatibility: Both use TO-220-3 through-hole packaging, enabling direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TYN616RG directly replace the S2016R in existing designs?

A: Yes. The TYN616RG is electrically and mechanically compatible with the S2016R. Gate trigger characteristics, on-state voltage, hold current, and operating temperature range are equivalent. The higher voltage rating (600V) does not affect operation in circuits designed for 200V operation.

Q: Why does the TYN616RG have a higher voltage rating than the S2016R?

A: The TYN616RG is rated for 600V off-state voltage compared to the S2016R's 200V rating. This uprating provides additional voltage margin and does not create compatibility issues in applications requiring 200V operation. The component will function identically in such circuits.

Q: Are the gate trigger parameters identical between these parts?

A: Gate trigger voltage (Vgt) is identical at 1.5V maximum. Gate trigger current (Igt) is 25mA maximum for the TYN616RG versus 30mA maximum for the S2016R, representing equivalent or improved performance.

Q: What is the on-state current rating for both parts?

A: Both the S2016R and TYN616RG are rated for 16A RMS on-state current (It (RMS)), with identical maximum on-state voltage (Vtm) of 1.6V.

Q: Are both components RoHS compliant?

A: Yes. Both the S2016R and TYN616RG are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the package type for both components?

A: Both components use the TO-220-3 through-hole package, enabling direct PCB footprint compatibility without layout modifications.
