Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SA207800L is based on electrical and mechanical compatibility within the PNP bipolar junction transistor category. The primary substitution criteria are:

Electrical Parameters:

• Transistor type must be PNP
• Maximum collector current must be equal to or greater than 100 mA
• Collector-emitter breakdown voltage must be equal to or greater than 50 V
• Package and mounting type must be compatible with SOT-723 surface mount applications

Mechanical Parameters:

• Package classification must be SOT-723
• Mounting type must be surface mount
• Moisture sensitivity level must be compatible (MSL 1 or equivalent)

The 2SA2029M3T5G meets these substitution criteria as an active product with equivalent electrical ratings and identical package specifications.
