S2010DS3TP Equivalent & Substitute Parts

Part Overview

The S2010DS3TP 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 part maintains ROHS3 compliance and operates across the industrial temperature range of -40°C to 110°C.

Substitute Part Grouping Explanation

Substitution for the S2010DS3TP is determined by maintaining compatibility across the following critical parameters:

SCR Type: Sensitive Gate classification must be preserved
Mounting Type: Surface mount configuration required
Package: TO-252-3 (DPAK) form factor with identical pinout
Gate Trigger Characteristics: Vgt and Igt parameters must remain within specified limits
On-State Performance: Vtm and It(RMS) ratings must support the application requirements
Temperature Range: Operating range of -40°C to 110°C must be maintained
Compliance: ROHS3 compliance required

The substitute parts S4010DS3TP and S6010DS3TP are qualified alternatives based on identical gate trigger specifications, on-state voltage and current ratings, hold current, operating temperature range, and package configuration. These parts differ only in off-state voltage rating, which represents an upgrade path for applications requiring higher voltage blocking capability.

Engineering Selection Recommendations

Direct Replacement: The S4010DS3TP and S6010DS3TP are active production parts from Littelfuse Inc. with current availability. Both maintain full electrical and mechanical compatibility with the S2010DS3TP across all gate trigger, on-state, and thermal parameters.

Voltage Rating Selection: Choose based on application voltage requirements:

S4010DS3TP: 400V off-state rating for applications requiring higher voltage blocking than 200V
S6010DS3TP: 600V off-state rating for applications requiring maximum voltage blocking capability

Both substitute parts carry ROHS3 compliance and maintain the same MSL-1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage practices. Active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can S4010DS3TP or S6010DS3TP be used as direct drop-in replacements for S2010DS3TP?

A: Yes. Both parts are pin-compatible in the TO-252-3 (DPAK) package and maintain identical gate trigger specifications (Vgt 800mV max, Igt 500µA max), on-state voltage (Vtm 1.6V max), and current ratings (It RMS 10A max). The higher off-state voltage ratings represent an upgrade capability for the same application circuit.

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

A: The S4010DS3TP and S6010DS3TP differ only in off-state voltage rating: 400V and 600V respectively, compared to the original 200V rating of S2010DS3TP. All other electrical and mechanical parameters remain identical.

Q: Are there any thermal or temperature-related differences?

A: No. All three parts operate across the identical temperature range of -40°C to 110°C with the same hold current and off-state leakage specifications.

Q: Why is the S2010DS3TP classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The S4010DS3TP and S6010DS3TP provide equivalent functionality with enhanced voltage ratings and active production status.

Q: Do the substitute parts require any circuit modifications?

A: No circuit modifications are required. The gate trigger characteristics, on-state performance, and package configuration are identical, allowing direct substitution in existing designs.

Q: What is the MSL rating for these parts?

A: All three parts carry MSL-1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.
