NTJS4160NT1G N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The NTJS4160NT1G is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 1.8A continuous drain current at 25°C. The device is housed in a 6-TSSOP/SC-88/SOT-363 surface mount package and dissipates up to 300mW. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, production continuity, and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NTJS4160NT1G is determined by alignment of the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• FET Type: N-Channel topology
• Technology: MOSFET (Metal Oxide)
• Drain-to-Source Voltage (Vdss): Must equal or exceed 30V
• Continuous Drain Current (Id): Must equal or exceed 1.8A at 25°C
• RDS(on): Lower or equivalent values indicate improved performance
• Gate Threshold Voltage (Vgs(th)): Compatibility with existing gate drive circuits
• Power Dissipation: Must support thermal requirements
• Operating Temperature Range: Must encompass -55°C to 150°C

Mechanical Compatibility Criteria:

• Package Type: 6-TSSOP, SC-88, or SOT-363 surface mount packages
• Mounting Type: Surface mount configuration
• Moisture Sensitivity Level: MSL 1 or equivalent

Substitute parts are grouped based on whether they meet or exceed these parameters while maintaining package compatibility and product availability status.

Parameter Comparison

Engineering Selection Recommendations

NTJS4405NT1G (onsemi)

This substitute is an active product from the same manufacturer. It shares identical package configuration and operating temperature range. However, the NTJS4405NT1G has a lower Vdss rating (25V versus 30V) and reduced continuous drain current (1.0A versus 1.8A). This part is suitable only for applications where the circuit operates at or below 25V and requires no more than 1.0A continuous drain current. The higher RDS(on) value (350 mOhm) results in increased power dissipation. This part carries RoHS3 compliance certification.

AO7412 (Alpha & Omega Semiconductor Inc.)

This substitute maintains the 30V Vdss rating and approaches the current capability of the original part (1.7A versus 1.8A). The AO7412 offers improved RDS(on) performance (90 mOhm versus 60 mOhm at comparable conditions), resulting in lower power dissipation during operation. Package configuration and operating temperature range are identical. This part is an active product with RoHS3 compliance certification and is suitable for direct substitution in applications requiring 30V operation and current levels up to 1.7A.

Frequently Asked Questions (FAQ)

Q: Can NTJS4405NT1G replace NTJS4160NT1G in all applications?

A: No. The NTJS4405NT1G has a lower Vdss rating (25V) and reduced continuous drain current (1.0A). It is suitable only for circuits operating at 25V or below with current requirements not exceeding 1.0A. Applications requiring the full 30V rating or 1.8A current capability must use AO7412 or equivalent.

Q: What is the primary difference between AO7412 and NTJS4160NT1G?

A: Both devices share the same 30V Vdss rating and similar current capability (1.7A versus 1.8A). The AO7412 has a slightly higher RDS(on) value (90 mOhm versus 60 mOhm) but offers improved gate threshold voltage characteristics. Both are housed in identical 6-TSSOP/SC-88/SOT-363 packages and operate across the same temperature range.

Q: Are all substitute parts available in the same package?

A: Yes. NTJS4160NT1G, NTJS4405NT1G, and AO7412 are all available in 6-TSSOP, SC-88, and SOT-363 surface mount packages. All are classified as MSL 1 (Unlimited moisture sensitivity level).

Q: What is the significance of the obsolete status of NTJS4160NT1G?

A: The obsolete status indicates that onsemi has discontinued production and support for this part. Both substitute options (NTJS4405NT1G and AO7412) are active products with ongoing manufacturer support, inventory availability, and compliance certifications.

Q: Which substitute is recommended for new designs?

A: Selection depends on circuit voltage and current requirements. For applications requiring 30V operation and current levels approaching 1.8A, AO7412 is the appropriate choice. For circuits operating at 25V or below with lower current demands, NTJS4405NT1G is acceptable. Both are active products with current compliance certifications.

Q: Are there compliance or regulatory differences between the substitutes?

A: NTJS4405NT1G carries RoHS3 compliance certification. AO7412 also carries RoHS3 compliance certification. Both parts are REACH Unaffected and classified as EAR99 for export control purposes. The original NTJS4160NT1G does not list RoHS status in the provided data.
