S2010DS3RP Equivalent & Substitute Parts

Part Overview

The S2010DS3RP is a Sensitive Gate SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage with 10A RMS current capability in a surface mount TO-252 (DPAK) package. Manufactured by Littelfuse Inc., this component is classified as obsolete. Due to its obsolete status and limited inventory availability (810 pcs), identifying equivalent substitute parts with higher voltage ratings and active product status is necessary for design continuity and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts for the S2010DS3RP are qualified based on the following criteria:

Electrical Compatibility Parameters:

SCR Type: Sensitive Gate (matching gate trigger characteristics)
Voltage - Gate Trigger (Vgt) (Max): 800 mV (identical)
Current - Gate Trigger (Igt) (Max): 500 µA (identical)
Voltage - On State (Vtm) (Max): 1.6 V (identical)
Current - On State (It (RMS)) (Max): 10 A (identical)
Current - Hold (Ih) (Max): 8 mA (identical)
Operating Temperature: -40°C ~ 110°C (identical)

Mechanical Compatibility Parameters:

Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63 (identical)
Mounting Type: Surface Mount (identical)

Voltage Rating Consideration: The substitute parts S4010DS3RP (400V) and S6010DS3RP (600V) feature higher off-state voltage ratings than the original 200V specification. These higher voltage ratings provide enhanced design margin and are electrically backward compatible in applications where the original 200V rating is sufficient, as the gate trigger and on-state characteristics remain identical.

Engineering Selection Recommendations

S4010DS3RP (400V Rating):

Active product status with substantial inventory (15,410 pcs)
ROHS3 compliant with REACH unaffected designation
Recommended for applications requiring immediate availability and long-term supply assurance
400V rating provides adequate margin for most industrial switching applications

S6010DS3RP (600V Rating):

Active product status with available inventory (726 pcs)
ROHS3 compliant with REACH unaffected designation
Recommended for applications requiring maximum voltage margin or higher system voltage tolerance
600V rating suitable for industrial and power conversion circuits with elevated transient voltage conditions

Both substitute parts maintain identical gate trigger characteristics, on-state performance, and thermal operating range, ensuring functional equivalence in circuit operation while providing superior supply chain continuity compared to the obsolete S2010DS3RP.

Frequently Asked Questions (FAQ)

Q: Can S4010DS3RP or S6010DS3RP be used as direct replacements for S2010DS3RP?

A: Yes. Both substitute parts are electrically and mechanically compatible. They feature 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), and operating temperature range (-40°C to 110°C). The higher voltage ratings (400V and 600V respectively) are backward compatible with 200V applications.

Q: What is the difference between S4010DS3RP and S6010DS3RP?

A: The primary difference is the off-state voltage rating: S4010DS3RP is rated for 400V while S6010DS3RP is rated for 600V. All other electrical and mechanical parameters are identical. Selection depends on the maximum voltage the application must withstand.

Q: Are the packages identical?

A: Yes. All three parts use the TO-252-3 DPAK package with 2 leads plus tab (SC-63). They are pin-compatible and suitable for the same PCB footprint.

Q: What is the inventory status for each part?

A: S2010DS3RP (obsolete) has 810 pcs available. S4010DS3RP (active) has 15,410 pcs available. S6010DS3RP (active) has 726 pcs available.

Q: Are all parts RoHS compliant?

A: Yes. S2010DS3RP, S4010DS3RP, and S6010DS3RP are all ROHS3 compliant. S4010DS3RP and S6010DS3RP also carry REACH unaffected designation.

Q: Which substitute should I select for a new design?

A: For new designs, either S4010DS3RP or S6010DS3RP is recommended due to active product status. Choose based on the maximum voltage your circuit must tolerate: 400V for standard industrial applications or 600V for applications with higher voltage transients or system requirements.
