2SC5751-T2-A Equivalent & Substitute Parts Reference

Part Overview

The CEL 2SC5751-T2-A is an NPN RF bipolar junction transistor designed for high-frequency applications up to 15GHz, rated for a maximum collector-emitter voltage of 6V and collector current of 50mA. The product is supplied in a SOT-343F surface-mount package and provides a typical noise figure of 1.7dB at 2GHz and a gain of 16dB. As the 2SC5751-T2-A is classified as obsolete, sourcing substitute parts with comparable electrical and mechanical specifications is necessary for new designs and maintenance support.

Key Parameters

Substitute Part Grouping Explanation

Substitute eligibility for RF transistors in the bipolar (BJT) category is determined by matching the transistor type (NPN), mounting type, and package style (SOT-343F, or equivalent). Compatibility also requires comparison of the voltage rating, transition frequency, noise figure, gain, power dissipation, collector current, DC current gain, and operating temperature. Substitution is validated only when these technical parameters fall within acceptable matching criteria for direct replacement.

Key parameters for substitution:

• Transistor Type
• Voltage - Collector Emitter Breakdown (Max)
• Frequency - Transition
• Noise Figure
• Gain
• Power - Max
• DC Current Gain (hFE) (Min)
• Current - Collector (Ic) (Max)
• Operating Temperature
• Mounting Type
• Package / Case

Parameter Comparison

Engineering Selection Recommendations

The primary selection factor is the product status: 2SC5751-T2-A is obsolete, while BFU610F,115 is active. Both parts are REACH unaffected. For direct substitution within the transistors, bipolar (BJT) category, only parts with matching compliance and package designations, such as SOT-343F, should be considered.

Frequently Asked Questions (FAQ)

Q1: What mechanical features must match when substituting 2SC5751-T2-A?
A1: The mounting type and package/case must be SOT-343F, as defined by both the main and substitute part parameters.

Q2: Are all listed substitute parts compliant for use in regulated markets?
A2: Both the main and substitute parts indicate REACH unaffected status and do not specify additional compliance requirements in the provided data.

Q3: Can the BFU610F,115 be used in applications requiring higher collector current or power?
A3: Substitute usage is constrained by the listed collector current (Ic Max) and power ratings. If original specifications require >10mA Ic or >136mW, evaluate parameters strictly as supplied.

Q4: How should noise figure and gain differences be managed for substitution?
A4: Only the provided values can be used. Applications sensitive to noise figure or gain must compare the parameters directly and select according to project specifications.

Q5: Is SOT-343F packaging identical between the main and substitute parts?
A5: Both parts specify SOT-343F, and mounting type as surface mount, permitting mechanical compatibility as per given parameters.
