S8010R SCR 800V 10A TO-220 Equivalent & Substitute Parts

Part Overview

The S8010R is a silicon-controlled rectifier (SCR) manufactured by Littelfuse Inc., rated for 800V off-state voltage with 10A RMS on-state current capability. This component is designed for standard recovery applications in Through Hole TO-220 packaging. The S8010R is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production needs.

Substitute Part Grouping Explanation

Substitution of the S8010R is determined by the following critical parameters:

Off-State Voltage Rating: All substitutes must maintain 800V minimum rating to ensure equivalent blocking capability
SCR Type: Standard Recovery classification must be preserved for consistent switching characteristics
Package / Case: TO-220-3 form factor ensures mechanical and thermal compatibility with existing PCB layouts
Operating Temperature Range: -40°C to 125°C range must be maintained for thermal envelope compatibility
RoHS Compliance: ROHS3 compliance status ensures regulatory alignment

The MCR8NG and TYN812RG both meet these core substitution criteria. Variations in on-state current ratings (8A and 12A respectively) and gate trigger parameters represent acceptable deviations within the standard recovery SCR category, provided the application current requirements do not exceed the substitute part's rating.

Engineering Selection Recommendations

MCR8NG (Littelfuse Inc.): This substitute is actively manufactured and stocked with 15,600 units available. It maintains identical off-state voltage, hold current, and operating temperature specifications. The reduced on-state current rating of 8A requires application verification if the original design operates above this threshold. The lower gate trigger voltage (1V vs. 1.5V) may reduce gate drive requirements. ROHS3 compliance and active product status ensure long-term availability and regulatory alignment.

TYN812RG (STMicroelectronics): This substitute offers the highest on-state current rating at 12A, providing margin above the original 10A specification. It maintains identical off-state voltage and operating temperature range. The gate trigger voltage of 1.3V is intermediate between the original and MCR8NG. Superior off-state leakage current (5µA vs. 10µA) indicates lower reverse leakage characteristics. With 26,200 units in stock and active product status, this part offers strong availability. ROHS3 and REACH compliance confirm regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can MCR8NG be used if my application requires 10A continuous current? A: No. The MCR8NG is rated for 8A RMS on-state current maximum. Applications requiring 10A continuous operation must use TYN812RG or equivalent parts rated for 10A or higher.

Q: What is the significance of the gate trigger voltage difference between these parts? A: Gate trigger voltage (Vgt) determines the minimum gate voltage required to initiate SCR conduction. The MCR8NG requires 1V maximum versus 1.5V for the S8010R. This lower threshold may reduce gate drive circuit complexity but does not affect substitutability if the gate drive circuit is designed for the lower voltage.

Q: Are all three parts mechanically compatible with existing PCB layouts? A: Yes. All three parts use TO-220-3 package configuration with identical pin spacing and mounting requirements. PCB footprints and thermal management designs require no modification.

Q: Does the lower off-state leakage current of TYN812RG provide any advantage? A: The TYN812RG off-state leakage of 5µA versus 10µA in the S8010R and MCR8NG indicates superior reverse blocking characteristics. This may reduce standby power consumption in applications with extended off-state periods.

Q: Are there any compliance differences between the substitute parts? A: All three parts are ROHS3 compliant. TYN812RG additionally carries REACH Unaffected status. Both substitutes meet the regulatory requirements of the discontinued S8010R.
