VN10LFTC N-Channel 60V 150mA MOSFET Equivalent & Substitute Parts

Part Overview

The VN10LFTC is an N-Channel MOSFET manufactured by Diodes Incorporated, designed for surface mount applications in the SOT-23-3 package. This device operates at 60V drain-to-source voltage with a continuous drain current rating of 150mA at 25°C and maximum power dissipation of 330mW. The VN10LFTC is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging and manufacturer options.

Frequently Asked Questions (FAQ)

Q: Can I use 2N7002LT1G as a direct replacement for VN10LFTC?

A: The 2N7002LT1G is electrically compatible for most applications but with important differences. The continuous drain current is rated at 115mA compared to the VN10LFTC's 150mA. If your circuit operates at or near 150mA, the 2N7002LT1G may not provide adequate current margin. The Rds On is also higher at 7.5 Ohm versus 5 Ohm. For applications operating below 115mA, the 2N7002LT1G is a suitable substitute. Both parts share the SOT-23-3 package and -55°C to 150°C operating range.

Q: What is the difference between 2N7002LT1G and 2N7002LT3G?

A: Both parts are manufactured by onsemi and share identical electrical specifications. The difference lies in the manufacturing date code and tape reel configuration. Both are active products with equivalent performance and can be used interchangeably. Selection between them depends on supplier availability and procurement lead times.

Q: Why does 2N7002K have lower Rds On than the VN10LFTC?

A: The 2N7002K is rated at 0.3 Ohm Rds On @ 500mA, 4.5V, which is significantly lower than the VN10LFTC's 5 Ohm @ 500mA, 10V. This difference reflects different measurement conditions. The 2N7002K is measured at a lower gate voltage (4.5V) and higher current (500mA), which produces lower on-resistance. The 2N7002K represents a performance upgrade with reduced power dissipation in switching applications.

Q: Are BSS138AKAR and SN7002NH6327XTSA2 suitable for non-automotive applications?

A: Yes. Both parts are automotive-qualified but can be used in general industrial and consumer applications. Automotive qualification indicates higher reliability and stricter manufacturing controls, making these parts suitable for any application requiring robust performance. The automotive qualification does not restrict their use to automotive circuits.

Q: What is the significance of the SOT-23-3 versus TO-236AB package designation?

A: SOT-23-3 and TO-236AB are equivalent package designations for the same physical form factor. TO-236-3, SC-59, SOT-23-3, and TO-236AB all refer to the same three-lead surface mount package with identical pin spacing and footprint. Parts specified with any of these designations are mechanically interchangeable on the PCB.

Q: Can I use a part with lower continuous drain current rating if my application only requires 100mA?

A: Yes, provided the part meets or exceeds your actual operating current requirement. The 2N7002 (115mA) and 2N7002L (115mA) are suitable for applications operating at 100mA. However, always verify that the selected part's Rds On and power dissipation specifications are acceptable for your specific circuit conditions, including worst-case temperature and gate drive voltage.

Q: Why is VN10LFTC marked as obsolete?

A: The VN10LFTC is obsolete due to market consolidation and the availability of superior alternatives from multiple manufacturers. The VN10LFTA, manufactured by the same supplier (Diodes Incorporated), provides identical specifications with active product status and better availability. Obsolescence does not indicate a design flaw but rather a natural product lifecycle transition.

Q: What should I consider when selecting between multiple active substitutes?

A: Selection should be based on: (1) Exact electrical specification match to your circuit requirements, (2) Supplier availability and lead time, (3) Cost considerations, (4) Qualification requirements (automotive-grade if needed), (5) Thermal margin requirements, and (6) Gate drive voltage compatibility. For applications with no special requirements, VN10LFTA provides the most direct replacement. For applications requiring higher current capacity or thermal margin, 2N7002K, BSS138AKAR, or SN7002NH6327XTSA2 are preferred.

Q: Is RoHS3 compliance important for my selection?

A: All recommended substitute parts are ROHS3 compliant, matching the VN10LFTC specification. If your application or end market requires RoHS compliance, all listed active substitutes meet this requirement. Verify RoHS compliance status with your supplier for any parts not explicitly listed in this reference.
