Substitute Part Grouping Explanation

Substitution of the 2SD1628F-TD-H is determined by strict equivalence across the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Transistor type: NPN configuration
• Collector current rating: minimum 5 A
• Collector-emitter breakdown voltage: minimum 20 V
• Maximum power dissipation: minimum 500 mW
• Transition frequency: minimum 120 MHz
• Operating temperature range: minimum 150°C (TJ)
• Mounting type: Surface Mount
• Package compatibility: TO-243AA or equivalent footprint
• RoHS3 compliance and MSL Level 1 rating

Parametric Equivalent Classification: The 2SD1628G-TD-E is a parametric equivalent manufactured by onsemi with identical electrical specifications and package designation. This part maintains all core performance parameters and differs only in product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel® vs. standard packaging).

Similar Substitute Classification: The PBSS302NX,115 manufactured by Nexperia USA Inc. is classified as a similar substitute. This part exceeds the minimum electrical requirements with higher collector current (5.3 A), superior power dissipation (2.1 W), higher transition frequency (140 MHz), and improved DC current gain (250 @ 2A, 2V). The PBSS302NX,115 is qualified to AEC-Q100 automotive standards and packaged in SOT-89 format, which maintains TO-243AA footprint compatibility.
