S2010VTP SCR 200V 10A TO-251 Equivalent & Substitute Parts

Part Overview

The S2010VTP is a Silicon Controlled Rectifier (SCR) rated for 200V off-state voltage with 10A RMS current capacity in a TO-251 (V-Pak/I-Pak) through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The S2010VTP maintains standard recovery characteristics suitable for general-purpose thyristor applications requiring moderate voltage ratings.

Substitute Part Grouping Explanation

Substitute parts for the S2010VTP are selected based on electrical and mechanical compatibility within the following criteria:

Mandatory Matching Parameters:

• Package / Case: TO-251-3 Short Leads, IPak, TO-251AA
• Mounting Type: Through Hole
• SCR Type: Standard Recovery
• Operating Temperature Range: -40°C to 125°C
• Gate Trigger Voltage (Vgt) Max: 1.5V
• Gate Trigger Current (Igt) Max: 15mA
• On-State Voltage (Vtm) Max: 1.6V
• Current - On State (It RMS) Max: 10A
• Hold Current (Ih) Max: 30mA
• Off-State Current Max: 10µA
• Non Rep. Surge Current: 83A/100A (50/60Hz)
• RoHS Status: ROHS3 Compliant

Variable Parameter (Allows Substitution):

• Voltage - Off State: Can be equal or higher rating (200V, 400V, or 600V)

The S4010VTP (400V) and S6010VTP (600V) are direct substitutes with higher voltage ratings, maintaining all other electrical and mechanical specifications. Higher voltage ratings provide enhanced circuit protection without compromising performance in 200V applications.

Parameter Comparison

Engineering Selection Recommendations

S4010VTP (400V Rating) is the primary substitute for new designs and production continuity. This part maintains active product status with Littelfuse, ensuring long-term availability and supply chain stability. The 400V rating provides a 2x safety margin over the original 200V specification while maintaining identical gate trigger, on-state, and thermal characteristics. ROHS3 compliance is maintained.

S6010VTP (600V Rating) is the secondary substitute option, offering maximum voltage headroom for applications requiring enhanced transient protection. This part also maintains active product status and full ROHS3 compliance. The 600V rating provides a 3x safety margin and is suitable for circuits with potential overvoltage conditions.

Both substitutes are packaged in identical TO-251-3 through-hole format with no PCB layout modifications required. Selection between S4010VTP and S6010VTP depends on circuit voltage stress analysis and design margin requirements.

Frequently Asked Questions (FAQ)

Q: Can S4010VTP or S6010VTP be used as direct replacements for S2010VTP in existing designs?

A: Yes. Both substitutes are pin-compatible in TO-251-3 through-hole packages with identical gate trigger, on-state voltage, and current ratings. No circuit modifications are required. The higher voltage ratings (400V and 600V) are backward-compatible with 200V applications.

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

A: The off-state voltage rating is the only electrical difference. S2010VTP is rated 200V, S4010VTP is rated 400V, and S6010VTP is rated 600V. All other parameters—gate trigger voltage, on-state voltage, current capacity, and thermal range—are identical.

Q: Why should I choose S4010VTP over S6010VTP?

A: S4010VTP provides adequate voltage margin for standard applications while maintaining the closest rating to the original 200V specification. S6010VTP is preferred when circuit analysis indicates potential transient overvoltages or when maximum design margin is required.

Q: Are there any package or mounting differences?

A: No. All three parts use identical TO-251-3 short-lead through-hole packages. PCB footprints and mounting procedures are identical.

Q: What is the product status significance?

A: S2010VTP is obsolete, meaning Littelfuse no longer manufactures or supports this part. S4010VTP and S6010VTP are active products with guaranteed long-term availability, supply continuity, and technical support from the manufacturer.

Q: Are all three parts RoHS3 compliant?

A: Yes. S2010VTP, S4010VTP, and S6010VTP all meet ROHS3 compliance requirements.
