Engineering Selection Recommendations

2PC4081R,115 (Nexperia USA Inc.)

This part is the manufacturer-recommended substitute, sharing the same base product number (2PC4081) with the obsolete 2PC4081R/ZLX. It maintains identical electrical specifications for collector current (150 mA), breakdown voltage (50 V), and power dissipation (200 mW). The part holds active product status with AEC-Q101 automotive qualification and full RoHS3 compliance. Packaging is identical (SC-70, SOT-323) in surface mount configuration. Inventory availability is substantial at 40,817 pieces.

2SD2351T106V (Rohm Semiconductor)

This alternative substitute meets all core electrical requirements with 150 mA collector current and 50 V breakdown voltage. It offers superior performance characteristics including lower saturation voltage (300mV versus 400mV), higher transition frequency (250MHz versus 100MHz), and higher DC current gain (820 versus 180). The part maintains active status with full RoHS3 and REACH compliance. Package configuration is identical (SC-70, SOT-323). Inventory availability is 4,096 pieces.

Both substitutes are suitable for direct replacement based on compliance certifications and electrical parameter alignment. Selection between them depends on application-specific performance requirements.

Frequently Asked Questions (FAQ)

Q: Can 2PC4081R,115 directly replace 2PC4081R/ZLX in existing designs?

A: Yes. Both parts share identical electrical specifications for maximum collector current (150 mA), breakdown voltage (50 V), and power dissipation (200 mW). Package configuration (SC-70, SOT-323) is identical. Both maintain RoHS3 compliance and MSL Level 1 rating.

Q: What are the key differences between the two substitute options?

A: The 2PC4081R,115 is the direct manufacturer-recommended equivalent with matching base product number.
