S2010DS2RP Equivalent & Substitute Parts

Part Overview

The S2010DS2RP 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. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The S2010DS2RP maintains electrical compatibility with higher voltage-rated alternatives within the same product family that share identical gate trigger characteristics, on-state voltage performance, and mechanical packaging.

Substitute Part Grouping Explanation

Substitute parts for the S2010DS2RP are selected based on electrical parameter compatibility within the Littelfuse Sensitive Gate SCR family. The substitution criteria are:

Preserved Parameters (Must Match):

Voltage - Gate Trigger (Vgt) Max: 800 mV
Current - Gate Trigger (Igt) Max: 200 µA
Voltage - On State (Vtm) Max: 1.6 V
Current - On State (It RMS) Max: 10 A
Current - Hold (Ih) Max: 6 mA
SCR Type: Sensitive Gate
Operating Temperature Range: -40°C to 110°C
Package / Case: TO-252-3, DPAK (2 Leads + Tab)
Mounting Type: Surface Mount

Variable Parameter (Allows Substitution):

Voltage - Off State: 200V, 400V, or 600V ratings are electrically compatible for applications requiring equal or lower voltage stress

The S4010DS2RP (400V) and S6010DS2RP (600V) are direct functional equivalents with higher voltage ratings, enabling use in circuits with increased voltage headroom while maintaining identical gate drive requirements and current handling characteristics.

Engineering Selection Recommendations

S4010DS2RP (400V Rating) is the primary substitute for applications where the original 200V rating is adequate but component availability is required. This part maintains active product status with ROHS3 compliance and is available in higher inventory quantities. Selection of the 400V variant provides voltage margin for transient overvoltage conditions while preserving all gate drive and current handling characteristics of the original design.

S6010DS2RP (600V Rating) is the secondary substitute for applications requiring maximum voltage headroom or where higher voltage stress conditions exist. This part is active with ROHS3 compliance and REACH Affected status. The 600V rating accommodates the widest range of circuit voltage conditions while maintaining identical gate trigger and on-state performance parameters.

Both substitutes are pin-compatible with the S2010DS2RP in TO-252 (DPAK) surface mount applications and require no circuit modifications beyond component replacement.

Frequently Asked Questions (FAQ)

Q: Can S4010DS2RP or S6010DS2RP be used as direct replacements for S2010DS2RP?

A: Yes. Both parts are electrically compatible substitutes with identical gate trigger voltage (800 mV max), gate trigger current (200 µA max), on-state voltage (1.6 V max), and current ratings (10 A RMS). The higher voltage ratings (400V and 600V) are backward compatible with 200V circuit designs. Pin configuration and package dimensions are identical.

Q: What is the difference between the three parts?

A: The S2010DS2RP, S4010DS2RP, and S6010DS2RP differ only in off-state voltage rating: 200V, 400V, and 600V respectively. All other electrical parameters, gate drive requirements, and thermal characteristics are identical. The higher voltage ratings provide increased voltage stress capability without affecting gate control or current handling.

Q: Why is S2010DS2RP listed as obsolete?

A: The S2010DS2RP is classified as obsolete by the manufacturer. The S4010DS2RP and S6010DS2RP are active products that provide equivalent functionality with higher voltage ratings and continued manufacturing support.

Q: Are there any compliance differences between these parts?

A: All three parts are ROHS3 compliant. The S6010DS2RP carries REACH Affected status, while the S2010DS2RP and S4010DS2RP do not list REACH impact. Verify REACH compliance requirements for your specific application and region.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of circuit voltage requirements. If the original design operates at voltages below 200V, any of the three parts will function identically. For circuits with voltage stress between 200V and 400V, use S4010DS2RP or S6010DS2RP. For circuits exceeding 400V, use S6010DS2RP only.

Q: What is the package compatibility?

A: All three parts use identical TO-252-3 (DPAK) surface mount packaging with 2 leads plus tab configuration. PCB footprints and reflow soldering profiles are identical. No layout modifications are required for substitution.
