2SD2674TL Equivalent & Substitute Parts Reference

Part Overview

2SD2674TL is an NPN bipolar junction transistor (BJT) manufactured by Rohm Semiconductor in the Transistors, Bipolar (BJT) product category. It supports 12 V collector-emitter breakdown voltage, 1.5 A collector current, 400 MHz transition frequency, and 1 W maximum power dissipation, with a TSMT3 (SC-96) surface-mount package. The part is RoHS3 compliant, REACH unaffected, and classified as active inventory. Engineering workflows may require alternative or equivalent models for supply continuity, second-source qualification, or to meet identical electrical and mechanical parameters within surface mount NPN transistor BOM needs.

Substitute Part Grouping Explanation

Equivalent and substitute NPN BJT parts are grouped strictly by matching or exceeding critical electrical and physical parameters: transistor type, collector-emitter breakdown voltage, maximum collector current, saturation voltage, current gain, cutoff current, transition frequency, power dissipation, operating temperature range, surface-mount packaging, RoHS/REACH compliance, and product active status. Package compatibility and supplier device package must be considered for direct replacement.

Frequently Asked Questions (FAQ)

Q1: What is required for a BJT to be considered an equivalent to 2SD2674TL?
A1: Key equivalency parameters are NPN type, collector-emitter voltage rating (≥12 V), maximum collector current (≥1.5 A), Vce(sat), cutoff current, DC current gain (hFE), power dissipation, transition frequency, maximum operating temperature, surface mount package, and regulatory compliance.

Q2: Are all substitute parts in the same package as 2SD2674TL?
A2: The main part uses SC-96 (TSMT3). Substitute parts use various compact surface mount packages including SMT3 and SOT-23-3 (TO-236). Exact package dimensions or pinout compatibility should be verified based solely on the provided package/case and supplier device package designations.

Q3: Do all alternatives have the same current gain and transition frequency?
A3: Current gain (hFE) and transition frequency (fT) values differ between parts. The minimum hFE for 2SD2674TL is 270 @ 200mA, 2V. Other substitutes list minimum hFE values according to varying test conditions.

Q4: What environmental or compliance certifications are present in all substitutes?
A4: All listed alternatives are classified as ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited), matching the main part.

Q5: Can these substitute NPN BJT transistors be used in the same application circuit?
A5: Based on strictly matched parameters—NPN type, collector voltage, collector current, surface mount form, and compliance status—all listed parts are suitable as direct substitutes according to the data provided. Application suitability regarding package or pin compatibility should be confirmed using the precise package/case identifier.
