Equivalent & Substitute Parts for 3LN01SS-TL-E

Part Overview

The 3LN01SS-TL-E is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 150mA continuous drain current. This device is packaged in a 3-SSFP (SC-81) surface mount configuration and is designed for low-power switching applications. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3LN01SS-TL-E is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• FET Type: N-Channel MOSFET (Metal Oxide technology)
• Drain to Source Voltage (Vdss): Must equal or exceed 30V
• Continuous Drain Current (Id): Must meet or exceed 150mA at 25°C
• Power Dissipation: Must support 150mW or greater
• Gate Voltage (Vgs): Must accommodate ±10V or greater range
• Mounting Type: Surface Mount configuration

Mechanical Compatibility Criteria:

• Package Type: Surface mount only
• Moisture Sensitivity Level: MSL 1 or equivalent

The substitute parts identified—NTS4001NT1G and RYM002N05T2CL—satisfy these criteria with enhanced electrical performance characteristics while maintaining surface mount compatibility. Both substitutes are active products with current manufacturing status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

NTS4001NT1G (onsemi): This substitute provides direct electrical compatibility with the 3LN01SS-TL-E while offering enhanced performance. The NTS4001NT1G delivers 270mA continuous drain current against the original 150mA specification, with improved on-resistance characteristics (1.5Ohm vs. 3.7Ohm). The device supports an extended gate voltage range (±20V vs. ±10V) and operates across a wider temperature range (-55°C to 150°C). The part is active in production with full RoHS3 compliance and REACH unaffected status. Package transition from SC-81 to SC-70-3 (SOT323) requires PCB layout modification. Inventory availability is substantial at 125,200 units.

RYM002N05T2CL (Rohm Semiconductor): This substitute offers higher voltage rating (50V vs. 30V) with 200mA continuous drain current, meeting the original 150mA requirement. The device maintains equivalent power dissipation (150mW) and operates at the same maximum junction temperature (150°C). On-resistance is 2.2Ohm at 200mA and 4.5V gate voltage. The part is active in production with RoHS3 compliance and REACH unaffected status. Package transition from SC-81 to SOT-723 (VMT3) requires PCB layout modification. Inventory availability is 18,875 units. The reduced gate voltage maximum (±8V vs. ±10V) requires circuit verification for gate drive compatibility.

Both substitutes are active products with current manufacturing support, eliminating obsolescence risk associated with the 3LN01SS-TL-E. Selection between substitutes depends on package footprint constraints and gate drive voltage requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the NTS4001NT1G directly replace the 3LN01SS-TL-E without circuit modification?

A: Electrical substitution is valid; however, package transition from SC-81 to SC-70-3 (SOT323) requires PCB layout modification. The NTS4001NT1G provides superior electrical performance with higher current rating (270mA vs. 150mA) and lower on-resistance (1.5Ohm vs. 3.7Ohm). Gate voltage compatibility is enhanced (±20V vs. ±10V), providing additional design margin.

Q: What are the key differences between the two substitute options?

A: NTS4001NT1G maintains the 30V Vdss rating with higher current capacity (270mA) and lower on-resistance. RYM002N05T2CL provides higher voltage rating (50V) with 200mA current capacity. RYM002N05T2CL has a reduced gate voltage maximum (±8V vs. ±10V), requiring verification against circuit gate drive specifications. Package footprints differ: NTS4001NT1G uses SC-70-3 (SOT323), while RYM002N05T2CL uses SOT-723 (VMT3).

Q: Are both substitutes available in production quantities?

A: Yes. NTS4001NT1G inventory is 125,200 units. RYM002N05T2CL inventory is 18,875 units. Both parts are active products with current manufacturing status.

Q: What compliance certifications apply to the substitute parts?

A: Both NTS4001NT1G and RYM002N05T2CL carry RoHS3 compliance and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8541.21.0095. Moisture sensitivity level is MSL 1 (Unlimited) for both substitutes, matching the original part.

Q: Does the higher Vdss rating of RYM002N05T2CL (50V vs. 30V) affect circuit operation?

A: Higher Vdss rating provides additional voltage margin and does not negatively affect circuit operation in applications designed for 30V maximum. The device operates safely at 30V with enhanced reliability margin. Gate voltage maximum (±8V) requires verification against circuit gate drive specifications.

Q: What package considerations apply when transitioning from 3LN01SS-TL-E?

A: The original 3LN01SS-TL-E uses SC-81 package. NTS4001NT1G uses SC-70-3 (SOT323), a smaller footprint requiring PCB redesign. RYM002N05T2CL uses SOT-723 (VMT3), the smallest footprint option. Both substitutes are surface mount devices with MSL 1 rating, maintaining equivalent moisture handling requirements.
