Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SB1412-P-TP is determined by strict equivalence across the following critical parameters: transistor type (PNP), maximum collector current (5A), collector-emitter breakdown voltage (30V), package type (DPAK surface mount), and regulatory compliance (ROHS3). Parts are classified into two categories based on these criteria.

Parametric Equivalents maintain identical electrical specifications and package configuration, differing only in product status (active versus obsolete) and packaging format (tape & reel versus bulk). These parts are direct functional replacements.

Similar Alternatives share the same transistor type, voltage rating, and current rating but exhibit enhanced performance characteristics in power dissipation, transition frequency, or DC current gain. These parts are suitable for applications where the original specification is met or exceeded, provided package compatibility is confirmed.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

The 2SB1412-Q-TP and 2SB1412-R-TP are parametric equivalents of the 2SB1412-P-TP. Both parts are manufactured by Micro Commercial Co and maintain identical electrical specifications: 5A collector current, 30V breakdown voltage, 1W power dissipation, 120MHz transition frequency, and 82 minimum DC current gain. Both are ROHS3 compliant and carry MSL 1 rating. The primary distinction is product status: both Q-TP and R-TP variants are active, whereas the P-TP is obsolete. The 2SB1412-R-TP offers higher inventory availability (3900 units) compared to 2SB1412-Q-TP (1199 units). Both are supplied in tape & reel packaging format.

For Enhanced Performance Applications:

The 2SAR572DGTL (Rohm Semiconductor) and STD888T4 (STMicroelectronics) are similar alternatives that exceed the original specification in power handling and frequency response. The 2SAR572DGTL provides 10W power dissipation and 300MHz transition frequency with improved DC current gain (200 minimum). The STD888T4 provides 15W power dissipation. Both maintain the 5A/30V core ratings and DPAK package configuration. These alternatives are suitable for applications where thermal margin or switching speed requirements exceed the original 2SB1412-P-TP specification.

All substitute parts are ROHS3 compliant and carry MSL 1 moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 2SB1412-Q-TP and 2SB1412-R-TP be used interchangeably with 2SB1412-P-TP?

A: Yes. Both Q-TP and R-TP variants are parametric equivalents with identical electrical specifications and DPAK package configuration. The primary difference is packaging format (tape & reel) and product status (active). Electrical performance and pin configuration are identical.

Q: What is the difference between parametric equivalents and similar alternatives?

A: Parametric equivalents (2SB1412-Q-TP, 2SB1412-R-TP) maintain identical electrical specifications across all measured parameters. Similar alternatives (2SAR572DGTL, STD888T4) meet or exceed the core voltage and current ratings but offer enhanced performance in power dissipation, transition frequency, or DC current gain. Similar alternatives are suitable when the original specification is met or exceeded.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—2SB1412-Q-TP, 2SB1412-R-TP, 2SAR572DGTL, and STD888T4—are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: Can STD888T4 or 2SAR572DGTL be used in place of 2SB1412-P-TP?

A: Yes, with design verification. Both parts maintain the 5A/30V core specifications and DPAK package. However, they offer enhanced performance characteristics: STD888T4 provides 15W power dissipation versus 1W original; 2SAR572DGTL provides 10W power dissipation and 300MHz transition frequency versus 120MHz original. These enhancements are compatible with applications designed for the original part, provided thermal and frequency requirements do not impose constraints.

Q: What is the inventory status of each substitute?

A: 2SB1412-R-TP has the highest availability at 3900 units. 2SB1412-Q-TP has 1199 units. 2SAR572DGTL has 5200 units. STD888T4 has 1983 units. The original 2SB1412-P-TP has 1144 units but is obsolete.

Q: Are there package compatibility concerns?

A: No. All listed parts use TO-252-3 DPAK surface mount package with identical pin configuration and footprint. No PCB layout modifications are required for substitution.

Q: What is the difference in Vce saturation between substitute parts?

A: The original 2SB1412-P-TP specifies 1V Vce saturation at 100mA/4A. The 2SAR572DGTL provides lower saturation voltage (400mV at 100mA/2A), indicating improved switching efficiency. The STD888T4 specifies 1.2V at 500mA/10A. Lower saturation voltage reduces power loss in switching applications.
