2SC39350PL Equivalent & Substitute Parts

Part Overview

The 2SC39350PL is an RF transistor manufactured by Panasonic Electronic Components, classified as an NPN bipolar junction transistor (BJT) designed for RF applications. This device operates at a maximum collector-emitter voltage of 10V with a transition frequency of 2.5GHz and maximum power dissipation of 150mW in a surface mount SC-70 (SOT-323) package.

The 2SC39350PL is designated as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this transistor is specified in existing designs.

Substitute Part Grouping Explanation

Substitution of the 2SC39350PL is determined by the following critical parameters:

Electrical Compatibility Requirements:

Transistor type must be NPN
Voltage - Collector Emitter Breakdown (Max) must be ≥10V
Operating temperature must support 150°C (TJ)
Package / Case must be SC-70 or SOT-323 compatible

Application Suitability Criteria:

Frequency - Transition capability must support RF operation
Power - Max dissipation must accommodate circuit requirements
Current - Collector (Ic) (Max) must meet or exceed application demands

The 15GN03MA-TL-E satisfies all electrical compatibility requirements. This onsemi device maintains the same collector-emitter breakdown voltage (10V), operating temperature (150°C), and package format (SC-70, SOT-323). The substitute part exceeds the original specifications in power dissipation (400mW vs. 150mW) and collector current capacity (70mA vs. 50mA), making it suitable for applications requiring the 2SC39350PL.

Engineering Selection Recommendations

The 15GN03MA-TL-E is a direct substitute for the 2SC39350PL based on the following factors:

Product Status: The 2SC39350PL is obsolete, while the 15GN03MA-TL-E is active and available with substantial inventory (30,100 pcs). This ensures long-term supply continuity and support.

Electrical Compatibility: Both devices share identical collector-emitter breakdown voltage (10V) and operating temperature rating (150°C). The SC-70 (SOT-323) package format is identical, enabling direct PCB layout compatibility without redesign.

Performance Margin: The 15GN03MA-TL-E provides enhanced specifications in power dissipation (400mW vs. 150mW) and collector current capacity (70mA vs. 50mA). These improvements provide design margin for thermal and current handling requirements.

Regulatory Compliance: The 15GN03MA-TL-E is ROHS3 compliant, whereas the 2SC39350PL is RoHS non-compliant. Selection of the substitute part aligns with current environmental and regulatory standards.

Frequency Consideration: The 2SC39350PL operates at 2.5GHz transition frequency, while the 15GN03MA-TL-E operates at 1.5GHz. For applications requiring operation above 1.5GHz, circuit performance validation is necessary to confirm suitability.

Frequently Asked Questions (FAQ)

Q: Can the 15GN03MA-TL-E directly replace the 2SC39350PL without PCB modifications?

A: Yes. Both devices use the SC-70 (SOT-323) package format with identical pinout and footprint. No PCB layout changes are required for physical substitution.

Q: What is the primary difference between these two transistors?

A: The 2SC39350PL operates at 2.5GHz transition frequency with 150mW maximum power dissipation. The 15GN03MA-TL-E operates at 1.5GHz with 400mW maximum power dissipation. The substitute part provides greater power handling capability but lower frequency performance.

Q: Is the 15GN03MA-TL-E suitable for all applications using the 2SC39350PL?

A: Substitution is valid for applications operating at or below 1.5GHz transition frequency. Applications requiring operation above 1.5GHz must be evaluated for performance impact.

Q: What is the difference in RoHS compliance between these parts?

A: The 2SC39350PL is RoHS non-compliant. The 15GN03MA-TL-E is ROHS3 compliant, meeting current environmental regulations for lead-free and restricted substance requirements.

Q: Are there packaging differences between the main part and substitute?

A: Both devices are supplied in surface mount SC-70 (SOT-323) packages. The 2SC39350PL uses SMini3-G1 supplier packaging, while the 15GN03MA-TL-E uses 3-MCP supplier packaging. The component packages are identical; only the tape and reel configuration differs.

Q: What is the DC current gain difference between these transistors?

A: The 2SC39350PL specifies DC current gain (hFE) of 75 minimum at 7.2mA collector current and 2.4V collector-emitter voltage. The 15GN03MA-TL-E specifies DC current gain (hFE) of 100 minimum at 10mA collector current and 5V collector-emitter voltage. These measurements are taken at different operating points and are not directly comparable.
