Equivalent & Substitute Parts for S2006DS2RP

Part Overview

The S2006DS2RP is a Sensitive Gate SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage with 6A RMS current capacity in a surface mount TO-252 (DPAK) package. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and production continuity. Substitute parts maintain identical gate trigger characteristics, on-state voltage performance, and package form factor while offering higher voltage ratings and active product status.

Substitute Part Grouping Explanation

Substitution of the S2006DS2RP is based on strict electrical and mechanical compatibility criteria. The substitute parts S4006DS2RP and S6006DS2RP maintain identical specifications across all critical parameters that define functional interchangeability:

Preserved Parameters (Substitution Basis):

• Gate trigger voltage (Vgt): 800 mV maximum
• Gate trigger current (Igt): 200 µA maximum
• On-state voltage (Vtm): 1.6 V maximum
• On-state current (It RMS): 6 A maximum
• Hold current (Ih): 6 mA maximum
• Off-state leakage current: 5 µA maximum
• Non-repetitive surge current: 83A/100A (50/60Hz)
• Operating temperature range: -40°C to 110°C
• Package form factor: TO-252-3 DPAK
• Mounting type: Surface Mount
• SCR type: Sensitive Gate

Variable Parameter (Upgrade Path):

• Voltage - Off State: 200V (main) → 400V (S4006DS2RP) → 600V (S6006DS2RP)

The higher voltage ratings of substitute parts provide enhanced overvoltage margin while maintaining identical gate drive requirements and current handling capacity, enabling direct circuit substitution in applications where the original 200V rating is limiting.

Engineering Selection Recommendations

S4006DS2RP Selection Criteria: The S4006DS2RP provides a 2x voltage upgrade (400V vs 200V) while maintaining all electrical performance characteristics. This part is in active production status with ROHS3 compliance and REACH affected classification. Selection is appropriate for applications requiring moderate voltage margin improvement over the original S2006DS2RP specification.

S6006DS2RP Selection Criteria: The S6006DS2RP provides a 3x voltage upgrade (600V vs 200V) with identical electrical performance. This part is in active production status with ROHS3 compliance and REACH unaffected classification. Selection is appropriate for applications requiring maximum voltage headroom or where supply chain availability of the 400V variant is constrained.

Both substitute parts are manufactured by Littelfuse Inc. and carry identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications as the original component. Moisture sensitivity level remains MSL 1 (Unlimited) across all variants.

Frequently Asked Questions (FAQ)

Q: Can S4006DS2RP or S6006DS2RP be used as direct replacements for S2006DS2RP? A: Yes. Both substitute parts maintain identical gate trigger voltage, gate trigger current, on-state voltage, on-state current, hold current, and operating temperature specifications. The TO-252 DPAK package and pin configuration are identical, enabling direct PCB substitution.

Q: What is the primary difference between the three parts? A: The off-state voltage rating is the only electrical parameter that differs. S2006DS2RP is rated 200V, S4006DS2RP is rated 400V, and S6006DS2RP is rated 600V. All other electrical and thermal characteristics are identical.

Q: Does the higher voltage rating of substitute parts affect gate drive circuit design? A: No. Gate trigger voltage (Vgt) and gate trigger current (Igt) specifications are identical across all three parts. Existing gate drive circuits require no modification.

Q: Are there any compliance or regulatory differences between these parts? A: All three parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications. S4006DS2RP is REACH affected; S6006DS2RP is REACH unaffected. Verify REACH compliance requirements for your specific application and supply chain.

Q: What is the inventory status of substitute parts? A: S2006DS2RP (obsolete) has 1126 pcs in stock. S4006DS2RP (active) has 4570 pcs in stock. S6006DS2RP (active) has 10400 pcs in stock.

Q: Can I use a lower voltage part as a substitute if my application only requires 200V? A: No. Substitution must use parts with equal or higher voltage ratings. Using a lower voltage rated part creates overvoltage risk and is not permitted.
