S4010LS3TP Equivalent & Substitute Parts

Part Overview

The S4010LS3TP is a Sensitive Gate SCR (Silicon Controlled Rectifier) rated for 400V off-state voltage with 10A RMS on-state current capacity. Manufactured by Littelfuse Inc. under the Teccor® series, this through-hole thyristor is designed for AC switching and control applications requiring low gate trigger requirements. The component is Active status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when electrical parameters remain within acceptable operating ranges for the intended application, maintaining voltage ratings, gate sensitivity characteristics, and thermal operating windows while potentially offering different current ratings or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

The S4008LS3TP qualifies as a parametric equivalent based on the following criteria:

Matching Parameters (Substitution Basis):

• Off-state voltage: 400V (identical)
• Gate trigger voltage (Vgt): 800 mV maximum (identical)
• Gate trigger current (Igt): 500 µA maximum (identical)
• On-state voltage (Vtm): 1.6V maximum (identical)
• Hold current (Ih): 8 mA maximum (identical)
• Off-state leakage current: 5 µA maximum (identical)
• Non-repetitive surge current: 83A/100A at 50/60Hz (identical)
• SCR type: Sensitive Gate (identical)
• Operating temperature range: -40°C to 110°C (identical)
• Package: TO-220-3 Full Pack, Isolated Tab (identical)
• Mounting: Through Hole (identical)
• RoHS3 compliance (identical)
• MSL rating: 1 Unlimited (identical)

Differing Parameter:

• Current - On State (It RMS) Max: 8A (substitute) vs. 10A (main part)

The S4008LS3TP operates within the same electrical envelope with reduced RMS current capacity, making it suitable for applications requiring ≤8A RMS operation.

Parameter Comparison

Engineering Selection Recommendations

S4010LS3TP Selection Criteria:

• Applications requiring maximum RMS current capacity of 10A
• Designs with average on-state current up to 6.4A
• Primary selection when full current rating headroom is required

S4008LS3TP Selection Criteria:

• Applications with RMS current requirements ≤8A
• Designs with average on-state current ≤5.1A
• Alternative when S4010LS3TP inventory is unavailable
• Both parts maintain identical gate sensitivity, voltage ratings, and thermal characteristics

Both parts carry Active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory compatibility across applications. Selection between these parts depends solely on the application's maximum current requirement within the specified operating temperature range of -40°C to 110°C junction temperature.

Frequently Asked Questions (FAQ)

Q: Can S4008LS3TP replace S4010LS3TP in all applications?

A: No. The S4008LS3TP is suitable only for applications where the maximum RMS current requirement does not exceed 8A and average on-state current does not exceed 5.1A. Applications requiring the full 10A RMS capacity of the S4010LS3TP must use the main part number.

Q: Are the gate trigger characteristics identical between these parts?

A: Yes. Both parts share identical gate trigger voltage (800 mV max) and gate trigger current (500 µA max), ensuring equivalent gate drive circuit requirements and control signal compatibility.

Q: Do both parts use the same package and mounting?

A: Yes. Both S4010LS3TP and S4008LS3TP use TO-220-3 Full Pack with isolated tab in through-hole mounting configuration, allowing direct PCB footprint compatibility.

Q: What is the temperature operating range for both parts?

A: Both parts operate across -40°C to 110°C junction temperature range, providing identical thermal performance windows for circuit design.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, carry MSL rating of 1 (Unlimited), and share identical regulatory status.

Q: What determines substitution eligibility for these SCR parts?

A: Substitution is based on matching off-state voltage (400V), gate sensitivity parameters (Vgt/Igt), on-state voltage characteristics (Vtm), hold current (Ih), package type, and operating temperature range. Current rating differences are the primary distinguishing factor.
