BFS 460L6 E6327 Equivalent & Substitute Parts

Part Overview

The BFS 460L6 E6327 is a dual NPN RF transistor manufactured by Infineon Technologies, designed for high-frequency applications up to 22 GHz. This component features a maximum collector-emitter breakdown voltage of 5.8V, maximum power dissipation of 200mW, and is housed in a 6-XFDFN surface mount package (TSLP-6-1).

The BFS 460L6 E6327 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical compatibility across critical RF parameters including frequency response, gain characteristics, noise figure, and thermal ratings.

Substitute Part Grouping Explanation

Substitution of RF transistors is determined by strict equivalence across electrical and mechanical parameters. The BFS 460L6 E6327 can be substituted with the BFR460L3E6327XTMA1 based on the following criteria:

Critical Matching Parameters:

• Voltage - Collector Emitter Breakdown (Max): 5.8V (identical)
• Frequency - Transition: 22 GHz (identical)
• Power - Max: 200mW (identical)
• DC Current Gain (hFE Min) @ 20mA, 3V: 90 (identical)
• Current - Collector (Ic) Max: 50mA (identical)
• Operating Temperature (TJ): 150°C (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)

Functional Differences: The BFR460L3E6327XTMA1 is a single NPN transistor (not dual) housed in a different surface mount package (SC-101, SOT-883 / PG-TSLP-3-1). The noise figure specification is marginally improved (1.1–1.35 dB vs. 1.1–1.4 dB), and the gain is specified at a single value (16 dB) rather than a range. The substitute part is currently active in production with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The BFR460L3E6327XTMA1 is the manufacturer-recommended substitute for the discontinued BFS 460L6 E6327. Both components are manufactured by Infineon Technologies and maintain identical electrical specifications across all critical RF parameters: breakdown voltage, transition frequency, maximum power dissipation, DC current gain, and maximum collector current.

Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance.

The primary design consideration is the package transition from 6-XFDFN (TSLP-6-1) to SC-101/SOT-883 (PG-TSLP-3-1). This requires PCB layout modification. Additionally, the BFR460L3E6327XTMA1 is a single NPN transistor rather than a dual configuration, necessitating circuit redesign if both transistors were utilized in the original design.

The substitute part is currently in active production with significantly higher inventory availability (15,872 pieces vs. 757 pieces for the original part), supporting long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the BFR460L3E6327XTMA1 directly replace the BFS 460L6 E6327 without circuit modification?

A: Direct replacement is not possible due to package differences and transistor configuration. The BFS 460L6 E6327 uses a 6-XFDFN package with dual NPN transistors, while the BFR460L3E6327XTMA1 uses an SC-101/SOT-883 package with a single NPN transistor. PCB layout redesign and circuit reconfiguration are required.

Q: Are the electrical specifications identical between these two parts?

A: The critical electrical specifications are identical: 5.8V breakdown voltage, 22 GHz transition frequency, 200mW maximum power, 50mA maximum collector current, and 90 minimum DC current gain at specified conditions. The noise figure and gain specifications show minor improvements in the substitute part.

Q: What is the impact of the single vs. dual transistor configuration?

A: The original BFS 460L6 E6327 contains two NPN transistors in one package. The BFR460L3E6327XTMA1 contains a single NPN transistor. If the original design utilized both transistors, two substitute parts would be required, or an alternative dual-transistor package must be selected.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the BFS 460L6 E6327 and BFR460L3E6327XTMA1 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL Level 1 (Unlimited), indicating unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: Why is the substitute part recommended despite package differences?

A: The BFR460L3E6327XTMA1 is the manufacturer-recommended substitute from Infineon Technologies. It maintains all critical RF electrical parameters and is in active production with superior inventory availability, ensuring long-term component supply security.
