Engineering Selection Recommendations

2SC1815 PBFREE (Central Semiconductor Corp)

This substitute provides direct electrical and mechanical compatibility with the 2PC1815GR,126. Both devices share identical voltage and current ratings (50 V, 150 mA), matching frequency response (80 MHz), and TO-92-3 through-hole packaging. The 2SC1815 PBFREE is active in production status, ensuring long-term procurement availability. RoHS3 compliance and REACH unaffected status align with regulatory requirements. The lower power rating (400 mW vs. 500 mW) and reduced DC current gain (70 @ 2mA, 6V vs. 200 @ 2mA, 6V) require circuit-level verification for applications dependent on these parameters.

2N6428 PBFREE (Central Semiconductor Corp)

This substitute exceeds the electrical specifications of the main part, offering higher collector current (200 mA vs. 150 mA), increased power dissipation (1.5 W vs. 500 mW), and higher transition frequency (100 MHz vs. 80 MHz). The TO-92-3 through-hole package maintains mechanical compatibility. Active product status supports procurement continuity. The higher DC current gain (250 @ 10mA, 5V) and increased Vce saturation (600mV @ 5mA, 100mA) represent parameter deviations that may affect circuit performance in saturation-dependent applications. RoHS3 compliance and REACH unaffected status are maintained.

BCX19,215 (Nexperia USA Inc.)

This substitute is suitable only for applications where surface-mount technology is acceptable. The device provides superior electrical performance with higher collector current (500 mA), matching transition frequency (100 MHz), and automotive-grade qualification (AEC-Q101). However, the reduced power rating (250 mW vs. 500 mW), lower collector-emitter breakdown voltage (45 V vs. 50 V), and surface-mount TO-236AB package represent significant deviations from the through-hole TO-92-3 configuration. This substitute is applicable only when PCB redesign for surface-mount assembly is feasible.

Frequently Asked Questions (FAQ)

Q: Can 2SC1815 PBFREE directly replace 2PC1815GR,126 in existing through-hole PCB designs?

A: Yes, 2SC1815 PBFREE provides direct mechanical and electrical compatibility. Both devices use TO-92-3 through-hole packaging and share identical voltage (50 V), current (150 mA), and frequency (80 MHz) specifications. Circuit verification is required for applications sensitive to DC current gain (hFE) differences, as 2SC1815 PBFREE specifies 70 @ 2mA, 6V versus 200 @ 2mA, 6V for the original part.

Q: What are the limitations of using 2N6428 PBFREE as a substitute?

A: 2N6428 PBFREE exceeds the original specifications in collector current (200 mA), power dissipation (1.5 W), and transition frequency (100 MHz). The TO-92-3 through-hole package is compatible. Primary limitations include higher Vce saturation voltage (600mV @ 5mA, 100mA vs. 300mV @ 10mA, 100mA) and different DC current gain characteristics. Applications relying on saturation performance or specific gain requirements require circuit-level analysis.

Q: Is BCX19,215 suitable for direct PCB replacement?

A: No. BCX19,215 uses surface-mount TO-236AB (SOT-23-3) packaging, incompatible with through-hole TO-92-3 footprints. This substitute requires PCB redesign and assembly process changes. Additionally, the reduced power rating (250 mW vs. 500 mW) and lower collector-emitter breakdown voltage (45 V vs. 50 V) may limit application scope. BCX19,215 is applicable only when surface-mount redesign is feasible and thermal/voltage margins are acceptable.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts (2SC1815 PBFREE, 2N6428 PBFREE, and BCX19,215) maintain RoHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original 2PC1815GR,126. BCX19,215 additionally carries automotive-grade qualification (AEC-Q101), suitable for automotive applications.

Q: How do DC current gain (hFE) differences affect circuit performance?

A: DC current gain determines base current requirements for saturation and amplification. The original 2PC1815GR,126 specifies 200 @ 2mA, 6V. 2SC1815 PBFREE specifies 70 @ 2mA, 6V (lower gain), requiring higher base current for equivalent collector current. 2N6428 PBFREE specifies 250 @ 10mA, 5V (higher gain at different operating point). Applications with fixed base current sources or gain-dependent biasing require circuit analysis to confirm compatibility.

Q: Are there temperature operating range differences between substitutes?

A: The original 2PC1815GR,126 specifies 150°C maximum junction temperature. 2N6428 PBFREE provides extended range (-65°C ~ 150°C), suitable for wider temperature environments. 2SC1815 PBFREE does not specify operating temperature range in provided data. BCX19,215 specifies 150°C maximum, matching the original. Applications in temperature-constrained environments should verify substitute specifications against system requirements.
