Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC370400L is determined by equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Transistor Type: NPN configuration
• Voltage - Collector Emitter Breakdown (Max): 10V minimum
• Power - Max: 200mW minimum
• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3 compatibility
• Operating Temperature: 150°C (TJ) minimum
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Performance Parameters (Application-Dependent):

• Frequency - Transition: 6GHz or higher
• Current - Collector (Ic) (Max): 80mA or higher
• Noise Figure and Gain characteristics for RF performance

The 2SC5227A-5-TB-E from onsemi meets all mandatory equivalence criteria and exceeds performance specifications in frequency (7GHz) and collector current capability (70mA nominal operation).

Parameter Comparison

Engineering Selection Recommendations

The 2SC5227A-5-TB-E qualifies as a direct substitute for the 2SC370400L based on electrical and mechanical parameter equivalence. Both devices share identical voltage ratings (10V), power dissipation capability (200mW), operating temperature range (150°C TJ), and package configuration (TO-236-3/SC-59/SOT-23-3 Surface Mount).

The 2SC5227A-5-TB-E demonstrates superior frequency performance (7GHz versus 6GHz transition frequency), supporting applications requiring extended bandwidth. The collector current specification of 70mA nominal operation remains within acceptable operating margins for designs originally specified for 80mA maximum.

The onsemi device carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for modern manufacturing environments. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification, eliminating special handling requirements.
