Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BFT25,215 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Transistor Type: NPN (required match)
• Voltage - Collector Emitter Breakdown (Max): Equal to or greater than 5V
• Frequency - Transition: Equal to or greater than 2.3GHz
• Power - Max: Equal to or greater than 30mW
• Current - Collector (Ic) (Max): Equal to or greater than 6.5mA
• Mounting Type: Surface Mount (required match)
• RoHS Status: ROHS3 Compliant (required match)

The substitute parts listed below meet or exceed these electrical and mechanical parameters, ensuring functional compatibility within RF circuit applications. Substitutes may operate at higher frequency ranges, higher voltage ratings, or higher power dissipation levels, all of which are acceptable for direct replacement in the BFT25,215 application space.

Parameter Comparison

Engineering Selection Recommendations

BFS17NTA (Diodes Incorporated)

The BFS17NTA is the most direct substitute for the BFT25,215. Both components share identical package configurations (TO-236-3, SC-59, SOT-23-3), enabling direct board-level replacement without layout modifications. The BFS17NTA operates at 3.2GHz, exceeding the 2.3GHz requirement, and provides 50mA maximum collector current against the 6.5mA specification of the BFT25,215. Power dissipation capability is 330mW, substantially exceeding the 30mW requirement. The BFS17NTA carries active product status with full ROHS3 compliance and unlimited moisture sensitivity level rating.

BFP540FESDH6327XTSA1 (Infineon Technologies)

The BFP540FESDH6327XTSA1 is suitable for applications requiring extended frequency performance. Operating at 30GHz with 5V collector-emitter breakdown voltage matching the original specification, this component provides 250mW power dissipation and 80mA maximum collector current. The 4-TSFP package differs from the original SOT-23 configuration and requires board layout adaptation. This substitute is appropriate for designs where higher frequency capability is beneficial or required. Active product status and ROHS3 compliance are confirmed.

BFR340FH6327XTSA1 (Infineon Technologies)

The BFR340FH6327XTSA1 operates at 14GHz with 9V collector-emitter breakdown voltage, providing enhanced frequency performance over the original 2.3GHz specification. Maximum collector current is 20mA with 75mW power dissipation. The SOT-723 package differs from the original SOT-23 configuration and requires board redesign. This substitute is applicable for RF applications requiring intermediate frequency performance between the original specification and ultra-wideband designs. Active product status and ROHS3 compliance are confirmed.

BFP183WH6327XTSA1 (Infineon Technologies)

The BFP183WH6327XTSA1 operates at 8.5GHz with 12V collector-emitter breakdown voltage, providing enhanced frequency and voltage performance. Maximum collector current is 65mA with 450mW power dissipation. The SOT-343 package differs from the original SOT-23 configuration and requires board layout modification. This substitute is applicable for designs requiring higher voltage operation or enhanced frequency performance. Active product status and ROHS3 compliance are confirmed.

All substitute parts carry active product status, ensuring long-term availability and supply chain continuity compared to the obsolete BFT25,215.

Frequently Asked Questions (FAQ)

Q: Can BFS17NTA directly replace BFT25,215 without board modifications?

A: Yes. Both components use identical package configurations (TO-236-3, SC-59, SOT-23-3), enabling direct pin-compatible replacement on existing printed circuit boards without layout changes.

Q: What is the primary advantage of BFS17NTA over other substitutes?

A: The BFS17NTA maintains package compatibility with the original BFT25,215, eliminating the need for board redesign. It also provides superior electrical performance with 3.2GHz frequency capability, 50mA collector current, and 330mW power dissipation, all exceeding original specifications.

Q: Are the other substitute parts (BFP540FESDH6327XTSA1, BFR340FH6327XTSA1, BFP183WH6327XTSA1) pin-compatible with BFT25,215?

A: No. These substitutes employ different package configurations (4-TSFP, SOT-723, and SOT-343 respectively) and require board layout modifications and redesign of the component footprint.

Q: What electrical parameters must a substitute part meet to be compatible with BFT25,215 applications?

A: A substitute must be an NPN transistor with collector-emitter breakdown voltage equal to or greater than 5V, transition frequency equal to or greater than 2.3GHz, maximum power dissipation equal to or greater than 30mW, and maximum collector current equal to or greater than 6.5mA. Surface mount mounting type and ROHS3 compliance are required.

Q: Why is the BFT25,215 listed as obsolete?

A: The BFT25,215 is no longer manufactured by NXP USA Inc. and is not available through standard distribution channels for new production orders. Substitute parts with active product status ensure continued design support and component availability.

Q: Do all substitute parts meet RoHS3 compliance requirements?

A: Yes. All listed substitute parts (BFS17NTA, BFP540FESDH6327XTSA1, BFR340FH6327XTSA1, BFP183WH6327XTSA1) carry ROHS3 Compliant certification, matching the environmental compliance status of the original BFT25,215.

Q: Can higher frequency-rated substitutes be used in lower frequency applications?

A: Yes. Substitute parts rated for higher frequency operation (such as BFP540FESDH6327XTSA1 at 30GHz) function correctly in applications operating at lower frequencies (such as 2.3GHz). The higher frequency capability does not degrade performance at lower operating frequencies.

Q: What is the operating temperature range for substitute parts?

A: BFS17NTA operates from −55°C to 150°C junction temperature. BFP540FESDH6327XTSA1, BFR340FH6327XTSA1, and BFP183WH6327XTSA1 operate to a maximum junction temperature of 150°C. The original BFT25,215 operates to 175°C maximum junction temperature.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are provided for reference. BFS17NTA (15,100 pcs), BFP183WH6327XTSA1 (15,266 pcs), and BFP540FESDH6327XTSA1 (3,259 pcs) are available in quantity. Inventory status may change; verification with component suppliers is recommended for production planning.
