2SC5015-A Equivalent & Substitute Parts Reference

Part Overview

The 2SC5015-A is an NPN RF bipolar junction transistor (BJT) designed for surface-mount applications, featuring a maximum collector-emitter voltage of 6V, a transition frequency of 12GHz, and a maximum power rating of 150mW. This device is currently classified as Obsolete. As a result, alternative transistor models with similar or compatible electrical and mechanical characteristics must be considered to maintain design continuity or facilitate repairs.

Substitute Part Grouping Explanation

Substitute parts for the 2SC5015-A are selected strictly based on the following key parameters: transistor type, maximum collector-emitter voltage, transition frequency, noise figure, gain, maximum power rating, current gain, maximum collector current, operating temperature, mounting type, and package/case. Only devices meeting or closely matching these characteristics are included. Mechanical compatibility (surface mount capabilities and comparable package dimensions) and minimum required compliance (MSL rating) are also considered.

Engineering Selection Recommendations

All listed substitute parts are in Active status and meet the minimum MSL 1 (Unlimited) requirement. RoHS and REACH compliance status is indicated where available. Selection based on these factors ensures ongoing supply, regulatory compliance, and handling compatibility.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for choosing a substitute for the 2SC5015-A?
A1: Substitution is based on transistor type, collector-emitter voltage, transition frequency, noise figure, gain, power rating, current gain, maximum collector current, operating temperature, mounting type, and package compatibility.

Q2: Are all substitute parts surface-mount devices?
A2: All substitutes except MRF327 are surface-mount devices. MRF327 is a chassis-mount device.

Q3: How important is package compatibility?
A3: Package compatibility is essential for direct replacement, especially when board layout modification is not possible. The SC-82A, SOT-343, and similar footprints are most compatible.

Q4: What is the significance of Moisture Sensitivity Level (MSL) in substitute selection?
A4: MSL 1 (Unlimited) means standard handling processes can be used, supporting reliable replacement with no need for special moisture precautions.

Q5: Why consider parts with higher voltage, current, or transition frequency ratings?
A5: Parts with higher ratings can typically fulfill the original function provided all other key parameters—particularly package, gain, noise, and mounting type—are suitable for the application.

Q6: Can through-hole or chassis-mount parts replace the 2SC5015-A in all cases?
A6: Chassis-mount alternatives like MRF327 may require board or mechanical redesign and are not suitable for all surface-mount layouts. Always confirm mounting compatibility.
