S2006VS3TP Equivalent & Substitute Parts

Part Overview

The S2006VS3TP is a 200V, 6A sensitive gate SCR (Silicon Controlled Rectifier) manufactured by Littelfuse Inc. in a TO-251 through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The S2006VS3TP maintains full electrical and mechanical compatibility with active alternative models that share identical gate trigger characteristics, on-state voltage parameters, and package specifications.

Engineering Selection Recommendations

S4006VS3TP (400V Rating): This substitute provides a 2x voltage upgrade from the original 200V specification while maintaining all electrical control characteristics. The S4006VS3TP is in active production status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment.

S6006VS3TP (600V Rating): This substitute provides a 3x voltage upgrade from the original 200V specification. The S6006VS3TP is in active production status with ROHS3 compliance and REACH unaffected designation. Selection of this part is appropriate for applications requiring maximum voltage margin within the sensitive gate SCR family.

Both substitute parts maintain identical gate drive requirements, on-state performance, and thermal operating range as the obsolete S2006VS3TP, enabling direct functional replacement in circuit designs. The choice between S4006VS3TP and S6006VS3TP depends on the application's voltage withstand requirements and design margin specifications.

Frequently Asked Questions (FAQ)

Q: Can S4006VS3TP or S6006VS3TP be used as direct replacements for S2006VS3TP?

A: Yes. Both substitute parts maintain identical gate trigger voltage (800 mV max), gate trigger current (500 µA max), on-state voltage (1.6 V max), on-state current (6 A RMS max), hold current (8 mA max), off-state current (5 µA max), SCR type classification (Sensitive Gate), operating temperature range (-40°C to 110°C), and TO-251 package configuration. The higher off-state voltage ratings represent design upgrades that do not affect circuit compatibility.

Q: What is the primary difference between the three SCR models?

A: The off-state voltage rating is the distinguishing parameter. S2006VS3TP is rated for 200V, S4006VS3TP for 400V, and S6006VS3TP for 600V. All other electrical and mechanical specifications remain identical across the three models.

Q: Are there any packaging differences between these parts?

A: No. All three models use the TO-251-3 Short Leads package (IPak, TO-251AA) with through-hole mounting configuration.

Q: What is the compliance status of the substitute parts?

A: Both S4006VS3TP and S6006VS3TP are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The S6006VS3TP and S4006VS3TP carry REACH unaffected designation, confirming regulatory alignment for current production environments.

Q: Why is the S2006VS3TP classified as obsolete?

A: The S2006VS3TP is listed as obsolete by the manufacturer. The active substitute parts S4006VS3TP and S6006VS3TP provide equivalent functionality with enhanced voltage ratings and confirmed long-term production availability.
