S4010DRP Equivalent & Substitute Parts

Part Overview

The S4010DRP is a Silicon Controlled Rectifier (SCR) rated for 400V off-state voltage with 10A RMS on-state current capability in a Surface Mount TO-252 (DPAK) package. Manufactured by Littelfuse Inc., this thyristor is classified as Standard Recovery type and is currently in active production status. Alternative part selection becomes necessary when addressing specific application requirements such as lower current ratings, packaging format preferences, or inventory availability constraints while maintaining electrical and mechanical compatibility within the 400V thyristor family.

Substitute Part Grouping Explanation

Substitution eligibility for the S4010DRP is determined by strict adherence to the following electrical and mechanical parameters:

Fixed Parameters (Non-Negotiable for Substitution):

• Voltage - Off State: 400V
• Voltage - Gate Trigger (Vgt) Max: 1.5V
• Current - Gate Trigger (Igt) Max: 15mA
• Voltage - On State (Vtm) Max: 1.6V
• Current - Hold (Ih) Max: 30mA
• Current - Off State Max: 10µA
• Operating Temperature Range: -40°C to 125°C
• Package / Case: TO-252-3, DPAK
• Mounting Type: Surface Mount
• SCR Type: Standard Recovery

Variable Parameters (Allowed to Differ):

• Current - On State (It RMS) Max: Substitutes must equal or exceed the application requirement but shall not exceed the main part rating
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for component selection purposes

The identified substitutes S4006DRP and S4008DRP maintain all fixed parameters while offering reduced on-state current ratings of 6A and 8A respectively, suitable for applications requiring lower current handling capacity within the same 400V thyristor platform.

Parameter Comparison

Engineering Selection Recommendations

S4010DRP (Primary Selection) Recommended for applications requiring the full 10A RMS on-state current rating. Active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Tape & Reel packaging format supports high-volume manufacturing environments.

S4008DRP (Intermediate Current Rating) Suitable for applications with on-state current requirements between 8A and 10A RMS. Maintains all electrical and thermal characteristics of the S4010DRP platform. Active production status with ROHS3 compliance. Tape & Reel packaging format available.

S4006DRP (Lower Current Rating) Applicable to applications with on-state current requirements of 6A RMS or lower. Provides cost optimization for reduced current handling scenarios while preserving gate trigger and thermal performance characteristics. Active production status with ROHS3 compliance. Cut Tape packaging format available; note REACH Status is listed as Affected for this variant.

All three parts maintain identical gate trigger voltage, hold current, and off-state leakage specifications, ensuring consistent gate drive circuit design across the substitution family.

Frequently Asked Questions (FAQ)

Q: Can S4006DRP or S4008DRP be used as direct replacements for S4010DRP in existing designs?

A: Direct substitution is not recommended. The S4006DRP and S4008DRP have lower on-state current ratings (6A and 8A RMS respectively) compared to the S4010DRP (10A RMS). Substitution is only valid when the application current requirement does not exceed the substitute part's rating. Circuit redesign or thermal analysis may be necessary to confirm suitability.

Q: Are the gate drive requirements identical across all three parts?

A: Yes. All three parts share identical gate trigger voltage (Vgt Max 1.5V) and gate trigger current (Igt Max 15mA) specifications. Gate drive circuits designed for S4010DRP are directly compatible with S4006DRP and S4008DRP.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape reels suitable for automated pick-and-place assembly in high-volume production. Cut Tape (CT) packaging is supplied in shorter tape segments, typically used for lower-volume orders or manual assembly. Both formats contain identical components; the difference is in supply format only.

Q: Are there thermal performance differences between the three parts?

A: The three parts share identical maximum on-state voltage (Vtm Max 1.6V) and operating temperature range (-40°C to 125°C). Thermal performance differences arise from the lower on-state current ratings of the S4006DRP and S4008DRP, which result in reduced power dissipation in current-limited applications.

Q: What is the significance of the REACH Status difference between S4010DRP and S4006DRP?

A: S4010DRP and S4008DRP are listed as REACH Unaffected, while S4006DRP is listed as REACH Affected. This indicates different regulatory compliance classifications under the REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) directive. Verify compliance requirements for your specific application and jurisdiction before selecting S4006DRP.
