Collector current rating (150 mA maximum)
Collector-emitter breakdown voltage (50 V maximum)
Vce saturation characteristics (400 mV @ 5mA, 50mA)
DC current gain (120 minimum @ 1mA, 6V)
Power dissipation (150 mW maximum)
Transition frequency (180 MHz)
Operating temperature range (150°C maximum junction temperature)

Engineering Selection Recommendations

2SC5658FHAT2LR (Primary Reference Part) This part is the baseline specification. It carries automotive grade qualification and AEC-Q101 certification with MSL Level 1 moisture sensitivity rating. Use this part number when Tape & Reel packaging and unlimited moisture exposure tolerance are required.

2SC5658FHAT2LQ (Automotive-Grade Equivalent) This part is electrically and mechanically identical to the 2SC5658FHAT2LR with the same automotive grade and AEC-Q101 qualification. The primary difference is MSL Level 3 (168 hours) moisture sensitivity. Selection of this part is appropriate when Tape & Reel packaging is required and moisture exposure can be controlled within 168-hour limits. Higher inventory availability (8297 pcs) may support procurement timelines.

2SC5658T2LQ (Cut Tape Packaging Equivalent) This part maintains all electrical specifications and RoHS3 compliance with MSL Level 1 rating. It differs from the primary part in packaging format (Cut Tape & Digi-Reel instead of Tape & Reel). This part is suitable for applications where cut tape or reel packaging is acceptable and automotive-grade certification is not explicitly required. Significantly higher inventory (90300 pcs) is available.

2SC5658T2LS (Cut Tape Packaging Equivalent) This part maintains all electrical specifications and RoHS3 compliance with MSL Level 1 rating. It differs from the primary part in packaging format (Cut Tape & Digi-Reel instead of Tape & Reel). This part is suitable for applications where cut tape or reel packaging is acceptable and automotive-grade certification is not explicitly required. Highest inventory availability (328200 pcs) supports rapid procurement.

Frequently Asked Questions (FAQ)

Q: Can 2SC5658T2LQ or 2SC5658T2LS be used in automotive applications requiring AEC-Q101 certification?

A: The 2SC5658T2LQ and 2SC5658T2LS parts do not carry automotive grade designation or AEC-Q101 qualification in the provided specifications. Use 2SC5658FHAT2LR or 2SC5658FHAT2LQ for applications with explicit automotive qualification requirements.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel packaging provides components on cut tape segments or alternative reel formats. Both formats are compatible with standard surface mount assembly equipment; selection depends on production volume and equipment configuration.

Q: Does MSL Level 3 (168 hours) affect circuit performance?

A: Moisture Sensitivity Level (MSL) is a handling and storage specification, not a performance specification. MSL Level 3 (168 hours) indicates the component can be exposed to ambient conditions (30°C, 85% relative humidity) for up to 168 hours before soldering. MSL Level 1 (Unlimited) allows indefinite storage under ambient conditions. Both ratings support identical electrical performance once soldered into the circuit.

Q: Are all substitute parts pin-compatible with the 2SC5658FHAT2LR?

A: Yes. All substitute parts use the SOT-723 package with identical pinout and mechanical dimensions. Direct substitution on printed circuit boards is supported without layout modifications.

Q: Which substitute part should be selected for maximum inventory availability?

A: The 2SC5658T2LS offers the highest inventory level (328200 pcs). If automotive qualification is not required and cut tape packaging is acceptable, this part supports immediate procurement. For automotive applications, 2SC5658FHAT2LQ provides the highest inventory among qualified parts (8297 pcs).

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes, within the constraints of your application requirements. All parts share identical electrical specifications (150 mA, 50 V, 180 MHz, 150 mW). Selection should be based on packaging format preference, moisture sensitivity requirements, and automotive qualification necessity.
