Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N5088_D81Z is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Transistor type must be NPN
• Collector-emitter breakdown voltage must equal or exceed 30 V
• Maximum collector current must equal or exceed 100 mA
• Maximum power dissipation must equal or exceed 625 mW
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Criteria:

• Package type must be TO-92-3 (Through Hole)
• Pin configuration must be compatible with TO-226-3 standard

Compliance Criteria:

• REACH compliance status must be unaffected or compliant
• ECCN classification must be EAR99

The 2N3904BU meets all substitution criteria. This device is an active product with enhanced electrical specifications, including higher collector current (200 mA), higher breakdown voltage (40 V), and superior frequency response (300 MHz), while maintaining identical power dissipation (625 mW) and package configuration (TO-92-3).

Parameter Comparison

Engineering Selection Recommendations

The 2N3904BU is a direct substitute for the 2N5088_D81Z based on the following factors:

Product Status: The 2N3904BU is classified as Active, ensuring long-term availability and supply chain continuity. The 2N5088_D81Z is obsolete, creating procurement risk and limiting future sourcing options.

Compliance Status: Both devices maintain REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory alignment for existing applications.

Electrical Performance: The 2N3904BU exceeds the minimum electrical requirements of the 2N5088_D81Z across all critical parameters. The higher collector current rating (200 mA vs. 100 mA), increased breakdown voltage (40 V vs. 30 V), and enhanced frequency response (300 MHz vs. 50 MHz) provide design margin and improved performance characteristics without compromising backward compatibility.

Package Compatibility: Both devices utilize identical TO-92-3 Through Hole packaging, enabling direct physical substitution without circuit board redesign.
