Key Parameters

Substitute Part Grouping Explanation

Substitution for the S2010VS2TP is determined by maintaining electrical and mechanical compatibility across the following critical parameters:

• SCR Type: Sensitive Gate configuration must be preserved
• Gate Trigger Characteristics: Vgt (Max) 800 mV and Igt (Max) 200 µA define gate drive requirements
• On-State Performance: Vtm (Max) 1.6 V and It (RMS) 10 A establish conduction specifications
• Hold Current: Ih (Max) 6 mA ensures latching behavior consistency
• Package Configuration: TO-251 through-hole mounting with identical lead configuration
• Operating Temperature Range: -40°C to 110°C operational envelope
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The substitute parts S4010VS2TP and S6010VS2TP maintain identical gate trigger, on-state voltage, hold current, and package specifications. The primary difference is elevated off-state voltage rating (400V and 600V respectively), which provides enhanced voltage margin while preserving all other electrical characteristics required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

S4010VS2TP is suitable for applications where the circuit operates at voltages up to 400V. This part is currently in active production status with 1039 units in stock, ensuring procurement availability. The 400V off-state rating provides a 2:1 voltage safety margin over the original S2010VS2TP specification while maintaining identical gate drive and conduction characteristics.

S6010VS2TP is suitable for applications requiring maximum voltage margin or operating in environments with transient voltage spikes. This part maintains active production status with 1800 units in stock, offering the highest voltage rating at 600V off-state. The 3:1 voltage safety margin over the original specification provides enhanced reliability in demanding applications while preserving all other electrical parameters.

Both substitute parts carry ROHS3 compliance and MSL Level 1 rating, matching the original component's environmental and regulatory qualifications. Selection between S4010VS2TP and S6010VS2TP depends solely on the maximum voltage the circuit must withstand.

Frequently Asked Questions (FAQ)

Q: Can S4010VS2TP or S6010VS2TP be used as direct replacements for S2010VS2TP?

A: Yes. Both parts maintain identical gate trigger voltage (800 mV max), gate trigger current (200 µA max), on-state voltage (1.6 V max), on-state current (10 A RMS max), hold current (6 mA max), and package configuration (TO-251). The elevated off-state voltage ratings provide additional design margin without affecting circuit operation.

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

A: The off-state voltage rating is the only electrical parameter that differs. S2010VS2TP is rated 200V, S4010VS2TP is rated 400V, and S6010VS2TP is rated 600V. All other electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. All three parts use the TO-251-3 Short Leads package configuration with identical pinout and mechanical dimensions. Direct PCB substitution is possible without layout modifications.

Q: Why is the S2010VS2TP obsolete while the substitutes are active?

A: The S2010VS2TP has been discontinued by Littelfuse Inc. The S4010VS2TP and S6010VS2TP remain in active production, providing long-term supply continuity for sensitive gate SCR applications in the 10A current range.

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

A: Yes. Both S4010VS2TP and S6010VS2TP carry ROHS3 compliance and MSL Level 1 rating, matching the original S2010VS2TP specifications.

Q: Which substitute should be selected for a new design?

A: Selection depends on the maximum voltage the circuit must withstand. For circuits operating below 200V, S4010VS2TP provides adequate margin. For circuits with higher voltage requirements or transient spike concerns, S6010VS2TP is appropriate. Both parts are in active production with adequate inventory.
