Engineering Selection Recommendations

2N6428 PBFREE Selection:

Recommended for direct through-hole replacement applications
Maintains identical package footprint compatibility (TO-92)
Exceeds electrical specifications with higher collector current (200 mA vs. 150 mA) and power rating (1.5 W vs. 500 mW)
Active product status ensures long-term availability
ROHS3 compliance maintained

BCX19,215 Selection:

Suitable for applications permitting surface-mount package transition
Provides superior electrical performance with 500 mA collector current capability
Active product status with AEC-Q101 automotive qualification
Requires PCB layout and assembly process modification
ROHS3 compliance maintained
Note: Collector-emitter breakdown voltage is 45 V (5 V lower than original specification)

Selection Constraints:

BCX19,215 is not recommended for applications requiring ≥ 50 V collector-emitter breakdown voltage
2N6428 PBFREE is the preferred substitute for direct form-fit-function replacement in through-hole designs

Frequently Asked Questions (FAQ)

Q: Can 2N6428 PBFREE be used as a direct replacement for 2PC1815Y,126?

A: Yes. Both devices are NPN transistors in TO-92 through-hole packages with identical 50 V collector-emitter breakdown voltage. The 2N6428 PBFREE meets or exceeds all electrical specifications of the original part, including collector current (200 mA vs. 150 mA) and power dissipation (1.5 W vs. 500 mW). No circuit modifications are required.

Q: What are the limitations of BCX19,215 as a substitute?

A: BCX19,215 operates with a 45 V collector-emitter breakdown voltage, which is 5 V lower than the 2PC1815Y,126 specification. This device is not suitable for applications requiring the full 50 V rating. Additionally, BCX19,215 is a surface-mount component (TO-236AB package), requiring PCB redesign and different assembly processes compared to the through-hole TO-92 original.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both 2N6428 PBFREE and BCX19,215 are ROHS3 compliant, matching the compliance status of the original 2PC1815Y,126.

Q: What is the product status of available substitutes?

A: Both substitute parts are classified as active products. The 2N6428 PBFREE is manufactured by Central Semiconductor Corp, and BCX19,215 is manufactured by Nexperia USA Inc. Active status ensures continued availability and supply chain support.

Q: Does BCX19,215 have automotive qualification?

A: Yes. BCX19,215 carries AEC-Q101 automotive qualification, making it suitable for automotive and high-reliability applications. The original 2PC1815Y,126 does not specify automotive qualification.

Q: What inventory levels are available for substitute parts?

A: 2N6428 PBFREE has 916 pieces in stock. BCX19,215 has 15,200 pieces in stock. Both parts are available as new original components.
