S2010DS2TP Equivalent & Substitute Parts

Part Overview

The S2010DS2TP is a Sensitive Gate SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage with 10A RMS current capability in a surface mount TO-252 (DPAK) package. Manufactured by Littelfuse Inc., this component is classified as obsolete. Due to its obsolete status and limited availability for new designs, equivalent substitute parts with higher voltage ratings are available to maintain design compatibility while ensuring long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts for the S2010DS2TP are selected based on the following criteria:

• Identical SCR Type: Sensitive Gate configuration maintained across all substitutes
• Identical Package: TO-252-3 DPAK surface mount package ensures mechanical and thermal compatibility
• Identical Current Rating: 10A RMS on-state current maintained for equivalent power handling
• Identical Gate Parameters: Gate trigger voltage (Vgt) and current (Igt) specifications match, ensuring gate drive circuit compatibility
• Identical On-State Voltage: Vtm (Max) 1.6V maintained for consistent voltage drop characteristics
• Identical Hold Current: Ih (Max) 6mA maintained for consistent latching behavior
• Identical Operating Temperature Range: -40°C ~ 110°C maintained for thermal compatibility
• Higher Voltage Rating: Substitute parts feature increased off-state voltage ratings (400V and 600V) while maintaining all other electrical characteristics, providing design flexibility for higher voltage applications

Parameter Comparison

Engineering Selection Recommendations

S4010DS2TP (400V Rating): This substitute is recommended for applications requiring higher voltage margin while maintaining identical current and gate drive characteristics. The part is in active production status, ensuring long-term availability and supply chain continuity. ROHS3 compliance is maintained.

S6010DS2TP (600V Rating): This substitute provides maximum voltage headroom for high-voltage applications. The part is in active production status with the highest inventory availability (2052 pcs), ensuring reliable supply for new designs. ROHS3 compliance is maintained.

Both substitutes maintain identical electrical performance in gate drive circuits, on-state voltage drop, and hold current characteristics, making them direct functional replacements in applications where the 200V rating of the original part is not a limiting constraint.

Frequently Asked Questions (FAQ)

Q: Can S4010DS2TP or S6010DS2TP be used as direct replacements for S2010DS2TP?

A: Yes, both parts are direct functional replacements. They maintain identical gate trigger parameters, on-state voltage, hold current, and current ratings. The higher voltage ratings provide additional design margin without affecting circuit operation at lower voltages.

Q: What is the primary difference between the three parts?

A: The off-state voltage rating is the only electrical difference. S2010DS2TP is rated for 200V, S4010DS2TP for 400V, and S6010DS2TP for 600V. All other electrical and thermal characteristics are identical.

Q: Are the packages identical?

A: Yes, all three parts use the TO-252-3 DPAK surface mount package with identical pinout and thermal characteristics. PCB layout and thermal management remain unchanged.

Q: Why is S2010DS2TP obsolete?

A: The part is classified as obsolete by the manufacturer. S4010DS2TP and S6010DS2TP are active production parts and are recommended for new designs.

Q: Do the substitute parts have the same compliance certifications?

A: Yes, all three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Which substitute should I select for a new design?

A: Selection depends on the application voltage requirement. For applications operating at or below 200V, either S4010DS2TP or S6010DS2TP can be used. S6010DS2TP offers the highest voltage margin and has the highest inventory availability.
