S8010DTP Equivalent & Substitute Parts

Part Overview

The S8010DTP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, rated for 800 V off-state voltage with 10 A RMS on-state current in a surface-mount TO-252 (DPAK) package. This thyristor is classified as Standard Recovery type and is currently in active production status. Equivalent and substitute parts are identified based on matching electrical characteristics, thermal operating range, package compatibility, and regulatory compliance to support design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the S8010DTP are selected based on the following criteria:

Primary Matching Parameters:

Off-state voltage rating: 800 V (mandatory)
Package type: TO-252 (DPAK) surface mount (mandatory)
RMS on-state current rating: equal to or greater than 10 A
Operating temperature range: minimum -40°C to 125°C
RoHS3 compliance and REACH unaffected status

Substitution Logic: Parts with higher RMS current ratings (12 A) are acceptable as they provide equivalent or superior current handling capability while maintaining the same voltage class and package footprint. Gate trigger characteristics may vary within the Standard Recovery and Sensitive Gate classifications, provided the part remains functionally compatible with the application's gate drive circuit requirements.

Engineering Selection Recommendations

MCR12DCNT4G (Littelfuse, Standard Recovery): This part is rated for 12 A RMS on-state current, exceeding the S8010DTP specification. It maintains identical off-state voltage (800 V), package type (TO-252 DPAK), and operating temperature range (-40°C to 125°C). Gate trigger voltage is lower (1 V max vs. 1.5 V), which may require gate drive circuit adjustment. Both parts are ROHS3 compliant and REACH unaffected. This substitute provides higher current capacity within the same thermal and voltage class.

MCR12DSNT4G (Littelfuse, Sensitive Gate): This part features a Sensitive Gate design with significantly reduced gate trigger current (200 µA vs. 15 mA), enabling lower gate drive power requirements. RMS on-state current is 12 A. Operating temperature range is -40°C to 110°C, which is 15°C lower than the S8010DTP maximum. All other electrical and compliance parameters align with the primary part. This substitute is suitable for applications where gate drive power minimization is a design priority, provided the thermal environment does not exceed 110°C.

TN815-800B-TR (STMicroelectronics, Standard Recovery): This part is rated for 8 A RMS on-state current, which is below the S8010DTP specification (10 A). It maintains 800 V off-state voltage, TO-252 DPAK package, and -40°C to 125°C operating range. Gate trigger characteristics (1.3 V, 15 mA) are comparable to the primary part. This substitute is applicable only in applications where the actual on-state current requirement does not exceed 8 A RMS. ROHS3 compliance and REACH unaffected status are confirmed.

Frequently Asked Questions (FAQ)

Q: Can MCR12DCNT4G be used as a direct replacement for S8010DTP? A: MCR12DCNT4G is electrically compatible as a substitute. Both are 800 V Standard Recovery SCRs in TO-252 DPAK packages with identical operating temperature ranges. The higher 12 A RMS rating provides additional current margin. Gate trigger voltage is lower (1 V vs. 1.5 V), which may require gate drive circuit verification to ensure adequate gate current delivery.

Q: What is the difference between MCR12DCNT4G and MCR12DSNT4G? A: Both are rated for 12 A RMS at 800 V in TO-252 DPAK packages. MCR12DCNT4G is Standard Recovery type with 20 mA gate trigger current. MCR12DSNT4G is Sensitive Gate type with 200 µA gate trigger current, requiring significantly less gate drive power. MCR12DSNT4G has a maximum operating temperature of 110°C versus 125°C for MCR12DCNT4G.

Q: Is TN815-800B-TR suitable for all S8010DTP applications? A: TN815-800B-TR is suitable only for applications where the on-state current requirement does not exceed 8 A RMS. The S8010DTP is rated for 10 A RMS, so this substitute cannot be used in designs requiring the full 10 A capacity. Verify actual circuit current requirements before selection.

Q: Are all substitute parts available in the same packaging format? A: No. S8010DTP is supplied in Tube packaging. MCR12DCNT4G and MCR12DSNT4G are supplied in Tape & Reel (TR) format. TN815-800B-TR is supplied in Cut Tape (CT) and Digi-Reel® format. Packaging format does not affect electrical compatibility but may impact procurement and assembly processes.

Q: Do all parts meet the same regulatory compliance standards? A: Yes. S8010DTP, MCR12DCNT4G, MCR12DSNT4G, and TN815-800B-TR are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
