NTJS3151PT2 P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The NTJS3151PT2 is a P-Channel MOSFET manufactured by onsemi, rated for 12V drain-to-source voltage with 2.7A continuous drain current at 25°C. The device is packaged in a 6-TSSOP (SC-88/SC70-6/SOT-363) surface mount configuration and dissipates a maximum of 625mW. The NTJS3151PT2 carries an obsolete product status, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Equivalent parts with active product status and improved compliance certifications are available within the NTJS3151 base product family.

Substitute Part Grouping Explanation

Substitution of the NTJS3151PT2 is determined by electrical and mechanical parameter equivalence across the NTJS3151 product family. All substitute parts maintain identical electrical specifications: 12V Vdss rating, 2.7A continuous drain current, 60mOhm on-resistance at specified conditions, 1.2V gate threshold voltage, 8.6nC gate charge, and 850pF input capacitance. All parts share the same 6-TSSOP surface mount package configuration, ensuring mechanical and thermal compatibility.

The primary distinction between the main part and substitute parts lies in product status and compliance certifications. The NTJS3151PT1G and NTJS3151PT2G variants are classified as active products with RoHS3 compliance, whereas the NTJS3151PT2 is obsolete and RoHS non-compliant. Packaging format differs between the main part (unspecified packaging) and substitute parts (Tape & Reel format), which affects procurement and handling but does not alter electrical performance or functional compatibility.

Both parts are available in Tape & Reel packaging format, suitable for automated assembly processes. The choice between NTJS3151PT1G and NTJS3151PT2G is determined by specific procurement requirements and inventory availability, as both parts are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Are the NTJS3151PT1G and NTJS3151PT2G electrically interchangeable with the NTJS3151PT2?

A: Yes. All three parts share identical electrical specifications including 12V Vdss, 2.7A continuous drain current, 60mOhm on-resistance, 1.2V gate threshold voltage, 8.6nC gate charge, and 850pF input capacitance. They are functionally equivalent in circuit applications.

Q: What is the difference between NTJS3151PT1G and NTJS3151PT2G?

A: Both parts are electrically and mechanically identical. The difference lies in the suffix designation assigned by onsemi. Both are active products with RoHS3 compliance and Tape & Reel packaging. Selection between the two is based on procurement availability and inventory requirements.

Q: Can the NTJS3151PT2 be replaced with NTJS3151PT1G or NTJS3151PT2G in existing designs?

A: Yes. The substitute parts are pin-compatible and functionally equivalent. The 6-TSSOP package configuration is identical across all three parts, enabling direct board-level substitution without design modification.

Q: What is the significance of the obsolete status of NTJS3151PT2?

A: Obsolete status indicates that onsemi has discontinued production of this specific part number. The NTJS3151PT1G and NTJS3151PT2G are active alternatives that provide equivalent functionality with continued manufacturer support and availability.

Q: Are there packaging differences between the main part and substitute parts?

A: The NTJS3151PT2 packaging format is unspecified in the provided data. The substitute parts NTJS3151PT1G and NTJS3151PT2G are supplied in Tape & Reel (TR) format, which is standard for automated assembly operations. Both formats are compatible with the same 6-TSSOP surface mount package.
