Engineering Selection Recommendations

2N6428 PBFREE (Central Semiconductor Corp)

The 2N6428 PBFREE is an active product offering direct electrical compatibility with the 2PC1815Y,412. This device exceeds the minimum electrical requirements with 200 mA collector current capacity, 50 V breakdown voltage, and 1.5 W power dissipation. The through-hole TO-92 package provides mechanical compatibility with existing through-hole PCB designs. ROHS3 compliance and REACH unaffected status align with current regulatory requirements. This substitute is suitable for applications requiring through-hole mounting and standard power levels.

BCX19,215 (Nexperia USA Inc.)

The BCX19,215 is an active automotive-grade product with AEC-Q101 qualification, offering enhanced electrical performance with 500 mA collector current and 100 MHz transition frequency. However, this device features a surface-mount TO-236AB (SOT-23-3) package and reduced maximum power dissipation of 250 mW. The BCX19,215 is applicable only to applications where surface-mount technology is acceptable and power dissipation requirements do not exceed 250 mW. The automotive qualification provides additional reliability assurance for demanding applications. ROHS3 compliance and REACH unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can the 2N6428 PBFREE directly replace the 2PC1815Y,412 in existing designs?

A: The 2N6428 PBFREE provides direct electrical and mechanical compatibility for through-hole applications. Both devices share identical 50 V breakdown voltage and TO-92 package configurations. The 2N6428 PBFREE exceeds the collector current and power dissipation specifications of the original part, ensuring functional compatibility in existing circuit designs without modification.

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

A: The BCX19,215 employs surface-mount technology (TO-236AB/SOT-23-3 package) rather than through-hole mounting, requiring PCB redesign for implementation. Additionally, maximum power dissipation is limited to 250 mW compared to the 500 mW specification of the 2PC1815Y,412. The BCX19,215 is suitable only for applications where surface-mount technology is feasible and power dissipation remains below 250 mW.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the 2N6428 PBFREE and BCX19,215 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements equivalent to the original 2PC1815Y,412.

Q: What is the primary advantage of the BCX19,215 over the 2N6428 PBFREE?

A: The BCX19,215 provides automotive-grade qualification (AEC-Q101) and significantly higher collector current capacity (500 mA versus 200 mA). These characteristics make the BCX19,215 suitable for automotive and high-reliability applications where enhanced performance specifications are required.

Q: Which substitute is recommended for standard industrial applications?

A: The 2N6428 PBFREE is recommended for standard industrial applications requiring through-hole mounting. This device maintains mechanical compatibility with existing designs while providing active product status, improved electrical performance, and current market availability.
