Engineering Selection Recommendations

2DC4672-13 (Diodes Incorporated): This direct manufacturer substitute is the primary recommendation for new production applications. It maintains identical electrical specifications to the 2SC4672-P-TP while offering superior current handling capability (3A vs. 2A) and increased power dissipation (900mW vs. 500mW). The part is in active production status with substantial inventory availability (22,800 pcs). Operating temperature range extends to -55°C, providing broader environmental compatibility. ROHS3 compliance and unlimited moisture sensitivity level are maintained.

2SC5994-TD-E (onsemi): This part is suitable for applications requiring enhanced frequency performance (420MHz vs. 210MHz) and higher power dissipation (1.3W). It maintains the 2A collector current rating and 50V breakdown voltage. The lower saturation voltage (300mV vs. 350mV) provides improved switching efficiency. Active product status and full compliance certifications are confirmed. Package designation differs (PCP vs. SOT-89), requiring verification of PCB layout compatibility.

2SD1623T-TD-E (onsemi): This substitute is applicable where the lower transition frequency (150MHz) is acceptable for the application. It maintains core electrical parameters with identical saturation voltage and current ratings. Active product status and full compliance are confirmed. The higher saturation voltage (400mV) should be evaluated against circuit requirements.

PBSS4250X,135 (Nexperia USA Inc.): This automotive-grade substitute (AEC-Q100 qualified) is specified for applications requiring automotive qualification. It maintains 2A collector current and 50V breakdown voltage with enhanced power dissipation (1W). The significantly higher DC current gain (300 @ 1A, 2V) and lower transition frequency (100MHz) require circuit evaluation. Active product status is confirmed.

2SC4672T100P (Rohm Semiconductor): This parametric equivalent provides identical electrical specifications to the 2SC4672-P-TP, including 210MHz transition frequency and 500mW power rating. However, product status is classified as "Not For New Designs," limiting its application to legacy system support and repair scenarios. Substantial inventory availability (87,300 pcs) supports ongoing maintenance requirements. Package designation (MPT3) differs from the original SOT-89.

Frequently Asked Questions (FAQ)

Q: Can the 2DC4672-13 be used as a direct replacement for the 2SC4672-P-TP in existing designs?

A: The 2DC4672-13 is electrically compatible with the 2SC4672-P-TP for all specified parameters. The higher current rating (3A vs. 2A) and power dissipation (900mW vs. 500mW) provide design margin. However, the supplier device package designation differs (SOT-89-3 vs. SOT-89). Verify that the specific package variant is compatible with your PCB footprint and assembly process before implementation.

Q: What is the primary difference between the PCP and SOT-89 package designations?

A: Both designations refer to the TO-243AA case outline, which is the physical package form factor. PCP and SOT-89 are supplier-specific package designations for the same mechanical outline. Verify with your PCB design files and assembly documentation that the specific supplier package designation is supported by your manufacturing process.

Q: Why is the 2SC4672T100P listed as "Not For New Designs"?

A: The 2SC4672T100P is a legacy product from Rohm Semiconductor. While it provides identical electrical specifications to the 2SC4672-P-TP, the manufacturer has discontinued active development and recommends against its use in new designs. This part is suitable for repair and maintenance of existing systems where the original specification is required.

Q: Which substitute part offers the best performance improvement over the 2SC4672-P-TP?

A: The 2SC5994-TD-E provides the most significant performance enhancement with a transition frequency of 420MHz (double the original 210MHz) and power dissipation of 1.3W (2.6 times the original 500mW). The lower saturation voltage (300mV vs. 350mV) improves switching efficiency. These enhancements are suitable for high-speed switching applications. Verify that the PCP package designation is compatible with your design.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed in this reference are ROHS3 compliant. All parts maintain unlimited moisture sensitivity level (MSL 1), indicating no special storage or handling requirements beyond standard component handling practices.

Q: What is the significance of the automotive-grade qualification for the PBSS4250X,135?

A: The PBSS4250X,135 carries AEC-Q100 automotive qualification, indicating it meets stringent reliability and performance standards established by the Automotive Electronics Council. This qualification is required for applications in automotive systems and other mission-critical environments where enhanced reliability documentation is mandated. Non-automotive applications do not require this qualification.

Q: Can I use the 2DC4672-13 in a circuit designed for the 2SC4672-P-TP without any modifications?

A: The 2DC4672-13 maintains all critical electrical parameters (50V breakdown, 2A minimum current, 350mV saturation voltage, 82 hFE minimum) and is mechanically compatible with the TO-243AA footprint. The higher current rating (3A) and power dissipation (900mW) provide design margin without requiring circuit modifications. Verify PCB layout compatibility with the specific supplier package designation before assembly.
