S2004DS2RP Equivalent & Substitute Parts

Part Overview

The S2004DS2RP is a Sensitive Gate SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage with 4A RMS current capability in a surface mount TO-252 (DPAK) package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part maintains full RoHS3 compliance and unlimited moisture sensitivity rating, suitable for industrial switching and control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the S2004DS2RP is determined by maintaining electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• SCR Type: Sensitive Gate (gate trigger characteristics must match)
• Voltage - Gate Trigger (Vgt) Max: 800 mV (identical)
• Current - Gate Trigger (Igt) Max: 200 µA (identical)
• Voltage - On State (Vtm) Max: 1.6 V (identical)
• Current - On State (It RMS) Max: 4 A (identical)
• Current - Hold (Ih) Max: 6 mA (identical)
• Current - Off State Max: 2 µA (identical)
• Current - Non Rep. Surge: 25A / 30A (identical)
• Operating Temperature Range: -40°C to 110°C (identical)

Mechanical Compatibility Criteria:

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

Voltage Rating Consideration: The off-state voltage rating may be upgraded to higher values (400V or 600V) while maintaining all other electrical parameters. Higher voltage ratings provide enhanced design margin and are electrically compatible with 200V applications.

Compliance Criteria:

• RoHS3 Compliant (required)
• Moisture Sensitivity Level 1 (required)

Parameter Comparison

Engineering Selection Recommendations

S4004DS2RP (400V Rating): This substitute provides a 2x voltage margin over the original S2004DS2RP while maintaining identical gate trigger characteristics and current ratings. The part is in active production status with established supply chain availability. RoHS3 compliance and MSL-1 rating are maintained. Selection is appropriate for applications requiring enhanced voltage headroom within the same thermal and current envelope.

S6004DS2RP (600V Rating): This substitute provides a 3x voltage margin over the original S2004DS2RP with identical electrical performance in gate drive and current handling. The part is in active production status. RoHS3 compliance is maintained; however, REACH status is listed as affected, requiring compliance verification for specific end-use applications. Selection is appropriate for applications requiring maximum voltage margin and long-term supply security.

Both substitutes maintain full electrical and mechanical compatibility with the S2004DS2RP across all specified parameters. Selection between S4004DS2RP and S6004DS2RP depends on application voltage requirements and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can S4004DS2RP or S6004DS2RP be used as direct replacements for S2004DS2RP?

A: Yes. Both substitutes maintain identical gate trigger voltage (800 mV), gate trigger current (200 µA), on-state voltage drop (1.6 V), RMS current rating (4 A), hold current (6 mA), and operating temperature range (-40°C to 110°C). The TO-252 DPAK package and surface mount configuration are identical. The higher voltage ratings (400V and 600V) are electrically compatible with 200V applications.

Q: What is the difference between S4004DS2RP and S6004DS2RP?

A: The primary difference is the off-state voltage rating: S4004DS2RP is rated for 400V while S6004DS2RP is rated for 600V. All other electrical parameters, including gate drive characteristics, current ratings, and thermal specifications, are identical. Both are active production parts with RoHS3 compliance.

Q: Are there any compliance differences between the substitutes?

A: Both substitutes are RoHS3 compliant with MSL-1 rating. S6004DS2RP has REACH status listed as affected, while S4004DS2RP status is unaffected. Applications subject to REACH regulations should confirm compliance requirements before selecting S6004DS2RP.

Q: Does the higher voltage rating of the substitutes affect circuit performance?

A: No. The higher voltage rating does not affect switching characteristics, gate drive requirements, or on-state performance. The substitutes operate identically to the S2004DS2RP in circuits designed for 200V operation, with the added benefit of increased voltage margin.

Q: Are the substitute parts available in the same packaging options?

A: Both S4004DS2RP and S6004DS2RP are supplied in Tape & Reel (TR) packaging. The S2004DS2RP is listed as obsolete with no current packaging specification. The TO-252 DPAK package configuration remains identical across all three parts.

Q: What is the product status of each part?

A: S2004DS2RP is obsolete. S4004DS2RP and S6004DS2RP are both in active production status, ensuring long-term availability and supply chain stability for new designs.
