Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD874A-S-TP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Transistor Type: NPN
• Current - Collector (Ic) Max: 1 A
• Voltage - Collector Emitter Breakdown (Max): 50 V
• Power - Max: 500 mW
• Mounting Type: Surface Mount
• Package / Case: TO-243AA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The 2SCR513P5T100 manufactured by Rohm Semiconductor meets all mandatory matching criteria. This part maintains identical electrical ratings for collector current, breakdown voltage, and power dissipation. Both devices are Surface Mount components in the TO-243AA package with equivalent environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 2SCR513P5T100 is a direct functional equivalent for the obsolete 2SD874A-S-TP. Both devices share identical electrical ratings for maximum collector current (1 A), collector-emitter breakdown voltage (50 V), and power dissipation (500 mW). Both are ROHS3 compliant with MSL 1 classification, meeting equivalent environmental and regulatory requirements.

The 2SCR513P5T100 offers the advantage of Active product status from Rohm Semiconductor, ensuring ongoing availability and supply chain continuity. The substitute part demonstrates superior performance characteristics in transition frequency (360 MHz versus 200 MHz) and lower collector cutoff current (1 µA versus 100 nA), while maintaining compatibility with the TO-243AA package footprint.

Both devices are classified under ECCN EAR99 and share identical HTSUS tariff codes, confirming regulatory equivalence for export and import purposes.

Frequently Asked Questions (FAQ)

Q: Can the 2SCR513P5T100 be used as a direct replacement for the 2SD874A-S-TP in existing designs?

A: Yes. Both devices are NPN transistors with identical maximum ratings for collector current (1 A), collector-emitter breakdown voltage (50 V), and power dissipation (500 mW). Both are Surface Mount components in the TO-243AA package with equivalent RoHS3 compliance and MSL 1 moisture sensitivity classification.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Micro Commercial Co versus Rohm Semiconductor) and product status (Obsolete versus Active). The 2SCR513P5T100 features higher transition frequency (360 MHz versus 200 MHz) and lower collector cutoff current (1 µA versus 100 nA). The 2SD874A-S-TP specifies an operating temperature range of -55°C to 150°C, while the 2SCR513P5T100 specifies 150°C maximum junction temperature.

Q: Are the package footprints identical?

A: Both devices use the TO-243AA package case. The supplier device packages differ (SOT-89 for the main part, MPT3 for the substitute), but these are equivalent designations for the same physical package footprint used in Surface Mount applications.

Q: What is the significance of the product status difference?

A: The 2SD874A-S-TP is classified as Obsolete, indicating discontinued manufacturing and limited availability. The 2SCR513P5T100 is Active, ensuring ongoing production and supply chain availability from Rohm Semiconductor.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity classification, and are classified under ECCN EAR99 with identical HTSUS tariff code 8541.21.0075.

Q: How do the saturation voltage characteristics compare?

A: The 2SD874A-S-TP specifies Vce saturation of 400mV at 50mA base current and 500mA collector current. The 2SCR513P5T100 specifies 350mV at 25mA base current and 500mA collector current, indicating slightly lower saturation voltage under the specified test conditions.

Q: What is the difference in DC current gain specifications?

A: The 2SD874A-S-TP specifies minimum hFE of 170 at 500mA collector current and 10V Vce. The 2SCR513P5T100 specifies minimum hFE of 180 at 50mA collector current and 2V Vce. These measurements are taken at different operating points and cannot be directly compared without circuit-specific analysis.
