BF570,215 Equivalent & Substitute Parts

Part Overview

The BF570,215 is an NPN bipolar junction transistor manufactured by Nexperia USA Inc., designed for surface mount applications in the TO-236AB package. This active-status component operates at a maximum collector current of 100 mA with a 15 V collector-emitter breakdown voltage and 250 mW power dissipation. The device is qualified to AEC-Q101 automotive standards and complies with ROHS3 and REACH requirements.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatible package geometries and compliance certifications. Alternative NPN transistors in the TO-236-3/SOT-23-3 package family with matching or superior ratings serve as functional replacements for the BF570,215 in circuit applications.

Engineering Selection Recommendations

PMBT2369,215 (Nexperia USA Inc.)

The PMBT2369,215 is a direct functional equivalent with identical electrical specifications to the BF570,215 except for doubled maximum collector current (200 mA versus 100 mA). Both devices share Nexperia manufacturing, AEC-Q101 qualification, automotive grade designation, and ROHS3 compliance. The PMBT2369,215 operates at the same maximum temperature (150°C) and maintains equivalent DC current gain and breakdown voltage specifications. This part is suitable for applications requiring the same performance envelope with potential for higher current handling.

CMPT2369 TR PBFREE (Central Semiconductor Corp)

The CMPT2369 TR PBFREE meets all electrical substitution criteria with superior current handling (500 mA maximum) and power dissipation (350 mW). The device maintains 15 V breakdown voltage and equivalent DC current gain specifications. Extended operating temperature range (-65°C to 150°C) provides broader thermal operation capability. ROHS3 compliance is confirmed. This part is suitable for applications where higher current capacity or extended temperature range is beneficial.

MMBT2369ALT1G (onsemi)

The MMBT2369ALT1G provides equivalent electrical performance with 200 mA maximum collector current and 15 V breakdown voltage. Extended operating temperature range (-55°C to 150°C) exceeds the BF570,215 specification. ROHS3 compliance is confirmed. DC current gain specification differs (20 @ 100mA, 1V versus 40 @ 10mA, 1V), reflecting different test conditions. This part is suitable for applications within the specified electrical parameters.

SMMBT2369ALT1G (onsemi)

The SMMBT2369ALT1G is electrically equivalent to the MMBT2369ALT1G with identical specifications: 200 mA maximum collector current, 15 V breakdown voltage, and extended temperature range (-55°C to 150°C). ROHS3 compliance is confirmed. The primary distinction is packaging format (Tape & Reel versus Cut Tape). This part is suitable for high-volume automated assembly applications.

Frequently Asked Questions (FAQ)

Q: Can the PMBT2369,215 directly replace the BF570,215 in all applications?

A: The PMBT2369,215 is electrically compatible with the BF570,215 across all specified parameters. Both devices share identical breakdown voltage (15 V), DC current gain (40 @ 10mA, 1V), maximum temperature (150°C), and package geometry (TO-236-3/SOT-23-3). The PMBT2369,215 provides doubled maximum collector current (200 mA), which does not restrict its use in circuits designed for 100 mA operation. Both parts carry AEC-Q101 qualification and automotive grade designation.

Q: What is the difference between the onsemi MMBT2369ALT1G and SMMBT2369ALT1G?

A: The MMBT2369ALT1G and SMMBT2369ALT1G are electrically identical with matching electrical specifications. The distinction is packaging format: MMBT2369ALT1G is supplied in Cut Tape (CT) & Digi-Reel® format, while SMMBT2369ALT1G is supplied in Tape & Reel (TR) format. Both are housed in SOT-23-3 (TO-236) packages and are suitable for surface mount assembly. Selection between these parts depends on assembly equipment compatibility and supply chain requirements.

Q: Are all substitute parts compatible with the BF570,215 package footprint?

A: All substitute parts listed are housed in TO-236-3, SC-59, or SOT-23-3 packages, which are mechanically and electrically equivalent surface mount packages with identical three-terminal NPN pin configurations. PCB footprints designed for the BF570,215 accommodate all listed substitute parts without modification.

Q: Does the CMPT2369 TR PBFREE meet automotive qualification requirements?

A: The CMPT2369 TR PBFREE is manufactured by Central Semiconductor Corp and does not carry AEC-Q101 qualification or automotive grade designation in the provided specifications. The BF570,215 and PMBT2369,215 both carry AEC-Q101 qualification and automotive grade designation. For applications requiring automotive qualification, the PMBT2369,215 is the preferred substitute.

Q: What is the significance of the extended temperature range in the CMPT2369 and onsemi parts?

A: The CMPT2369 TR PBFREE operates from -65°C to 150°C, while the MMBT2369ALT1G and SMMBT2369ALT1G operate from -55°C to 150°C. The BF570,215 specification lists only the maximum junction temperature of 150°C. Extended lower temperature limits provide operational capability in colder environments. For applications operating within the BF570,215 specified range, this extended capability does not restrict substitution.

Q: How do DC current gain specifications differ between parts?

A: The BF570,215, PMBT2369,215, and CMPT2369 TR PBFREE specify DC current gain (hFE) minimum of 40 at 10 mA collector current and 1 V collector-emitter voltage. The MMBT2369ALT1G and SMMBT2369ALT1G specify DC current gain minimum of 20 at 100 mA collector current and 1 V collector-emitter voltage. These represent different test conditions reflecting device design characteristics. Both specifications meet the minimum gain requirements for typical switching applications.

Q: What packaging options are available for the substitute parts?

A: The PMBT2369,215 is available in Cut Tape (CT) & Digi-Reel® format. The CMPT2369 TR PBFREE is available in Tape & Reel (TR) format. The MMBT2369ALT1G is available in Cut Tape (CT) & Digi-Reel® format. The SMMBT2369ALT1G is available in Tape & Reel (TR) format. Selection depends on assembly equipment compatibility and supply chain logistics.
