SK010DTP Equivalent & Substitute Parts

Part Overview

The SK010DTP is an SCR (Silicon Controlled Rectifier) rated at 1 kV off-state voltage with 10 A RMS on-state current capability, manufactured by Littelfuse Inc. in a Surface Mount TO-252 (DPAK) package. This thyristor operates across the temperature range of -40°C to 125°C and is classified as Standard Recovery type. The part is currently Active in product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or application-specific requirements where lower current ratings are acceptable.

Substitute Part Grouping Explanation

The SK006DTP qualifies as a parametric equivalent to the SK010DTP based on the following substitution criteria:

Matching Parameters (Substitution Basis):

Voltage - Off State: 1 kV (identical)
Voltage - Gate Trigger (Vgt) (Max): 1.5 V (identical)
Current - Gate Trigger (Igt) (Max): 15 mA (identical)
Voltage - On State (Vtm) (Max): 1.6 V (identical)
Current - Hold (Ih) (Max): 30 mA (identical)
Current - Off State (Max): 20 µA (identical)
SCR Type: Standard Recovery (identical)
Operating Temperature: -40°C to 125°C (identical)
Mounting Type: Surface Mount (identical)
Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63 (identical)
RoHS Status: ROHS3 Compliant (identical)
Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)

Differing Parameter (Current Rating):

Current - On State (It (RMS)) (Max): 6 A (SK006DTP) vs. 10 A (SK010DTP)

The SK006DTP is suitable as a substitute where the application requires a maximum on-state RMS current of 6 A or less. All other electrical, thermal, and mechanical characteristics remain equivalent.

Engineering Selection Recommendations

Both the SK010DTP and SK006DTP are Active products manufactured by Littelfuse Inc. with identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). Both parts share the same package footprint (TO-252-3 DPAK) and are pin-compatible for PCB assembly.

Selection between these parts depends solely on the maximum on-state current requirement of the application. The SK010DTP supports up to 10 A RMS on-state current, while the SK006DTP supports up to 6 A RMS on-state current. All other electrical characteristics, thermal performance, and regulatory compliance are equivalent. Choose the SK006DTP as a substitute only when the application circuit operates within the 6 A RMS maximum current specification.

Frequently Asked Questions (FAQ)

Q: Can SK006DTP replace SK010DTP in any application? A: The SK006DTP can replace the SK010DTP only in applications where the maximum on-state RMS current does not exceed 6 A. If the circuit requires current handling above 6 A RMS, the SK006DTP is not suitable.

Q: Are these parts pin-compatible? A: Yes. Both parts use the TO-252-3 DPAK package with identical pin configuration (2 Leads + Tab, SC-63). PCB layouts designed for SK010DTP will accommodate SK006DTP without modification.

Q: Do these parts have the same gate trigger characteristics? A: Yes. Both parts have identical gate trigger voltage (Vgt Max: 1.5 V) and gate trigger current (Igt Max: 15 mA), ensuring equivalent gate drive requirements.

Q: What is the primary difference between these parts? A: The primary difference is the maximum on-state current rating. SK010DTP is rated for 10 A RMS, while SK006DTP is rated for 6 A RMS. All other electrical, thermal, and mechanical specifications are identical.

Q: Are both parts compliant with current regulations? A: Yes. Both SK010DTP and SK006DTP are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use SK010DTP in place of SK006DTP? A: Yes. The SK010DTP can be used in applications designed for SK006DTP, as it provides higher current capacity while maintaining all other equivalent specifications. This substitution introduces no compatibility issues.
