Equivalent & Substitute Parts Reference for 2SC5751-A

Part Overview

The 2SC5751-A is an NPN bipolar junction transistor (BJT) designed for RF applications, featuring a maximum collector-emitter breakdown voltage of 6V, transition frequency of 15GHz, and maximum collector current of 50mA. This device is housed in a SOT-343F surface mount package and provides a noise figure of 1.7dB at 2GHz with a minimum DC current gain of 75 at 20mA, 3V. The product is obsolete, making it necessary to identify suitable substitute models that meet the original key parameters for continued design or production support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SC5751-A must match the original part’s electrical and mechanical parameters within the product’s category: RF bipolar transistors. The key parameters used for grouping substitutes are: transistor type (NPN), collector-emitter breakdown voltage, transition frequency, noise figure, gain, maximum power, minimum DC current gain, maximum collector current, operating temperature, mounting type, and package/case. Only parts matching these criteria can be considered equivalents for direct replacement.

Engineering Selection Recommendations

The 2SC5751-A is obsolete and classified as “REACH Unaffected” with ECCN EAR99. Selection of substitutes such as BFU610F,115 must be based on product status (active), mounting compatibility (Surface Mount, SOT-343F), and inventory availability, as provided. No additional compliance or certification factors are introduced beyond those stated in the input.

Frequently Asked Questions (FAQ)

Q1: What parameters are crucial for substituting the 2SC5751-A?
A1: The determining parameters are transistor type (NPN), collector-emitter breakdown voltage, transition frequency, noise figure, gain, power rating, DC current gain, maximum collector current, operating temperature, mounting type, and package/case.

Q2: Is package compatibility mandatory when selecting a substitute?
A2: Yes. Both the original and substitute parts must use the SOT-343F surface mount package, ensuring physical compatibility on existing PCB designs.

Q3: How does product status affect selection?
A3: Substitute selection must prioritize parts that are active, in production, or available in inventory, to replace the obsolete part without supply chain disruption.

Q4: Are certification and compliance factors considered in substitution?
A4: Only the provided REACH status, ECCN, and HTSUS information are considered. No further certification analysis is applied.

Q5: Can substitutes with differing electrical ratings be used?
A5: Only parameters strictly matching or within specified limits as outlined in the key parameters table are included as substitutes. No extrapolations or modifications are made.
