Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC5347AF-TD-E requires evaluation of RF transistor performance across critical electrical and mechanical parameters. The primary substitution criteria are:

Electrical Compatibility Parameters:

• Transistor type (NPN topology)
• Collector-emitter breakdown voltage rating (minimum 12V required)
• Frequency capability (minimum 4.7GHz transition frequency required)
• Power dissipation capacity (minimum 1.3W required)
• Maximum collector current (minimum 150mA required)

Mechanical & Environmental Compatibility:

• Surface mount packaging capability
• Operating temperature range (minimum 150°C junction temperature)
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The identified substitute parts are evaluated against these criteria. Parts that do not meet all electrical requirements are classified as partial substitutes with specific application limitations noted.

Parameter Comparison

Engineering Selection Recommendations

BFS17NTA (Diodes Incorporated): This substitute is an active product with ROHS3 compliance and MSL 1 rating, matching the environmental specifications of the main part. However, the BFS17NTA exhibits reduced electrical performance: transition frequency of 3.2GHz falls below the 4.7GHz requirement, maximum power dissipation of 330mW is insufficient for the 1.3W specification, and maximum collector current of 50mA is below the 150mA requirement. The collector-emitter breakdown voltage of 11V is marginally lower than the 12V specification. This part is suitable only for applications where frequency, power, and current requirements can be relaxed below the original design specifications.

MAPR-000912-500S00 (MACOM Technology Solutions): This substitute is an active product with ROHS3 compliance and MSL 1 rating. The device offers significantly higher power handling (500W) and collector current (52.5A) with elevated breakdown voltage (80V) and operating temperature (200°C). However, the transition frequency is not specified, and the mounting type is chassis mount rather than surface mount, making this part incompatible with the original surface-mount PCB design. This part is applicable only to high-power RF applications with different mechanical integration requirements.

Both substitutes present significant deviations from the original 2SC5347AF-TD-E specifications. Selection of either substitute requires comprehensive circuit re-evaluation and performance validation against the intended application requirements.

Frequently Asked Questions (FAQ)

Q: Can the BFS17NTA directly replace the 2SC5347AF-TD-E in the same circuit?

A: Direct replacement is not recommended. The BFS17NTA has lower transition frequency (3.2GHz vs. 4.7GHz), reduced power dissipation capability (330mW vs. 1.3W), and lower maximum collector current (50mA vs. 150mA). Circuit redesign and performance testing are required if this substitute is considered.

Q: What are the key electrical differences between the main part and BFS17NTA?

A: The primary differences are transition frequency (3.2GHz vs. 4.7GHz), power rating (330mW vs. 1.3W), collector current rating (50mA vs. 150mA), and collector-emitter breakdown voltage (11V vs. 12V). These parameters directly affect RF performance and power handling capability.

Q: Is the MAPR-000912-500S00 suitable for RF applications at 4.7GHz?

A: The transition frequency for the MAPR-000912-500S00 is not specified in the available data. Additionally, this part is a chassis-mount device, not surface-mount, making it mechanically incompatible with the original TO-243AA PCP package design.

Q: Do both substitute parts meet RoHS and MSL requirements?

A: Yes. Both BFS17NTA and MAPR-000912-500S00 are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the environmental compliance of the 2SC5347AF-TD-E.

Q: What is the primary reason the 2SC5347AF-TD-E requires substitution?

A: The 2SC5347AF-TD-E is classified as obsolete, meaning it is no longer manufactured or available through standard distribution channels. Substitute parts must be identified to maintain design continuity and support ongoing production requirements.

Q: Are there any package compatibility considerations between the main part and substitutes?

A: Yes. The 2SC5347AF-TD-E uses TO-243AA (PCP) surface-mount packaging. The BFS17NTA uses SOT-23-3 surface-mount packaging, requiring PCB layout modifications. The MAPR-000912-500S00 uses chassis-mount packaging, which is fundamentally incompatible with surface-mount designs.

Q: What parameters should be prioritized when selecting a substitute?

A: For RF applications, transition frequency and power dissipation are critical. For the 2SC5347AF-TD-E, any substitute must support minimum 4.7GHz operation and 1.3W power handling. Collector current rating (150mA minimum) and collector-emitter breakdown voltage (12V minimum) are also essential for circuit functionality.
