S6016R Equivalent & Substitute Parts

Part Overview

The S6016R is a silicon-controlled rectifier (SCR) manufactured by Littelfuse Inc., rated for 600 V off-state voltage and 16 A RMS on-state current in a TO-220-3 through-hole package. This component is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 125°C and complies with ROHS3 standards.

Key Parameters

Parameter	S6016R Value
Voltage - Off State	600 V
Current - On State (It (RMS)) (Max)	16 A
Voltage - Gate Trigger (Vgt) (Max)	1.5 V
Current - Gate Trigger (Igt) (Max)	30 mA
Voltage - On State (Vtm) (Max)	1.6 V
Current - Hold (Ih) (Max)	40 mA
Current - Off State (Max)	10 µA
SCR Type	Standard Recovery
Package / Case	TO-220-3
Operating Temperature	-40°C ~ 125°C
RoHS Status	ROHS3 Compliant

Substitute Part Grouping Explanation

Substitution eligibility for the S6016R is determined by the following critical parameters:

Off-state voltage rating of 600 V
RMS on-state current rating of 16 A or higher
Standard Recovery SCR type
TO-220-3 package configuration
Operating temperature range of -40°C to 125°C
ROHS3 compliance

The three substitute parts listed below meet these core requirements. Differences in gate trigger voltage, gate trigger current, and non-repetitive surge current do not prevent functional substitution when the primary electrical ratings align.

Engineering Selection Recommendations

TYN616RG (STMicroelectronics) is the primary substitute for the S6016R. This part maintains identical electrical specifications for off-state voltage (600 V), RMS on-state current (16 A), gate trigger voltage (1.5 V), and on-state voltage (1.6 V). The TYN616RG carries Active product status with 28,500 units in stock, ensuring long-term availability. ROHS3 compliance and REACH Unaffected status confirm regulatory alignment.

SCT616B (SMC Diode Solutions) provides a direct 16 A RMS current rating with 600 V off-state voltage. This part exhibits lower gate trigger current (15 mA) and gate trigger voltage (1.3 V) compared to the S6016R. SCT616B is classified as Obsolete with 1,771 units available. ROHS3 compliance is confirmed; however, REACH Affected status requires verification for regulated markets.

TYN625RG (STMicroelectronics) offers increased current capacity at 25 A RMS on-state current while maintaining 600 V off-state voltage. This part is suitable for applications requiring higher current margins. TYN625RG is Active with 1,505 units in stock and carries ROHS3 compliance and REACH Unaffected status. Gate trigger voltage is 1.3 V with 40 mA gate trigger current.

Frequently Asked Questions (FAQ)

Q: Can SCT616B replace S6016R in all applications? A: SCT616B meets the core electrical requirements of 600 V off-state voltage and 16 A RMS on-state current. However, its Obsolete status and REACH Affected classification may limit suitability for new designs or regulated markets. Verify compliance requirements for your specific application.

Q: What is the advantage of using TYN625RG over TYN616RG? A: TYN625RG provides 25 A RMS on-state current compared to 16 A in TYN616RG. This higher current rating offers design margin for applications approaching the 16 A limit. Both parts share identical 600 V off-state voltage and Active product status.

Q: Are all substitute parts pin-compatible with S6016R? A: All substitute parts use the TO-220-3 package configuration. Physical pin compatibility is maintained across S6016R, SCT616B, TYN616RG, and TYN625RG. Verify gate, cathode, and anode terminal assignments in device datasheets before PCB layout finalization.

Q: Does lower gate trigger current in SCT616B or TYN625RG affect circuit design? A: Gate trigger current specifications (15 mA for SCT616B, 40 mA for TYN625RG) define the maximum gate current required for device triggering. Lower values indicate easier gate drive requirements. Circuit designs must accommodate the specified maximum values; lower actual requirements do not necessitate design changes.

Q: Which substitute offers the best long-term availability? A: TYN616RG maintains Active product status with the highest inventory level (28,500 units). This part is recommended for new designs requiring extended production lifecycles and supply chain stability.
