S2010VS3TP Equivalent & Substitute Parts

Part Overview

The S2010VS3TP is a sensitive gate SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage with 10A RMS current capacity in a TO-251 through-hole package. This component is classified as obsolete, making equivalent or substitute parts necessary for new designs and ongoing production requirements. The S2010VS3TP maintains electrical compatibility with higher voltage-rated alternatives from the same manufacturer series that share identical gate trigger characteristics, on-state voltage performance, and thermal operating range.

Substitute Part Grouping Explanation

Substitution for the S2010VS3TP is based on the following criteria:

Electrical Compatibility Parameters:

Gate trigger voltage (Vgt) and current (Igt) must remain identical at 800 mV maximum and 500 µA maximum
On-state voltage (Vtm) must not exceed 1.6 V maximum
On-state RMS current rating must equal or exceed 10 A
Hold current (Ih) must not exceed 8 mA
SCR type must be Sensitive Gate
Operating temperature range must encompass -40°C to 110°C

Mechanical Compatibility Parameters:

Mounting type must be Through Hole
Package must be TO-251-3 Short Leads, IPak, or TO-251AA

Regulatory Compliance:

RoHS3 compliance required

The S4010VS3TP and S6010VS3TP are direct substitutes because they maintain all gate trigger characteristics, on-state performance parameters, thermal range, and mechanical packaging while offering higher off-state voltage ratings (400V and 600V respectively). Higher voltage ratings provide design margin in applications where the original 200V specification may be insufficient.

Engineering Selection Recommendations

S4010VS3TP (400V Rating): This part is recommended for applications requiring higher voltage margin than the original 200V specification while maintaining identical gate drive and current handling characteristics. Product status is Active with current manufacturing availability, ensuring long-term supply continuity.

S6010VS3TP (600V Rating): This part provides maximum voltage headroom within the Littelfuse sensitive gate SCR series and is suitable for applications with elevated voltage transient requirements. Product status is Active with confirmed inventory, supporting both new designs and production replacements.

Both substitute parts maintain ROHS3 compliance and identical thermal operating ranges, ensuring direct functional replacement in existing circuit designs without modification to gate drive circuitry or thermal management provisions.

Frequently Asked Questions (FAQ)

Q: Can S4010VS3TP or S6010VS3TP be used as direct replacements for S2010VS3TP?

A: Yes. Both parts are direct substitutes. They maintain identical gate trigger voltage (800 mV max), gate trigger current (500 µA max), on-state voltage (1.6 V max), RMS current rating (10 A), hold current (8 mA max), operating temperature range (-40°C to 110°C), and TO-251 package configuration. The higher off-state voltage ratings (400V and 600V) provide additional design margin without affecting gate drive requirements or thermal characteristics.

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

A: The off-state voltage rating is the only electrical difference. S2010VS3TP is rated for 200V, S4010VS3TP for 400V, and S6010VS3TP for 600V. All other electrical parameters, including gate trigger characteristics and current handling, are identical.

Q: Are there any package or mounting differences?

A: No. All three parts use the TO-251-3 Short Leads (IPak/V-Pak) through-hole package with identical pin configuration and mechanical dimensions.

Q: Why is the S2010VS3TP obsolete while the substitutes are active?

A: The S2010VS3TP has been discontinued by Littelfuse Inc. The S4010VS3TP and S6010VS3TP remain in active production, providing continued availability for new designs and production support.

Q: Do the substitute parts require any circuit modifications?

A: No. Gate drive circuitry, current limiting, and thermal management provisions remain unchanged. The higher voltage ratings are transparent to circuit operation when the original 200V specification is not a limiting factor.

Q: Are all three parts RoHS3 compliant?

A: Yes. S2010VS3TP, S4010VS3TP, and S6010VS3TP are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.
