Key Parameters

Substitute Part Grouping Explanation

Substitution of the BGS8L5UKZ is determined by the following critical parameters:

• Frequency Coverage: The substitute must support the 703MHz to 960MHz band or a compatible subset that covers the application's required frequency range.
• Package Type: Surface mount 6-XFDFN package maintains mechanical and thermal compatibility with the original design.
• Electrical Performance: Gain and noise figure specifications must be within acceptable design margins for the target application.
• RF Application Class: LTE and cellular RF amplifier classification ensures functional equivalence.
• Supply Voltage and Current: Operating parameters must be compatible with existing power delivery infrastructure.
• Compliance Standards: RoHS3 compliance and MSL rating ensure environmental and handling compatibility.

Parameter Comparison

Engineering Selection Recommendations

The BGA7L1N6E6327XTSA1 manufactured by Infineon Technologies qualifies as a substitute for the obsolete BGS8L5UKZ based on the following criteria:

• Package Compatibility: Both components use the 6-XFDFN surface mount package, ensuring mechanical and thermal compatibility with existing PCB layouts.
• Frequency Coverage: The substitute supports 728MHz to 960MHz, which covers the upper portion of the original 703MHz to 960MHz range. Applications requiring coverage below 728MHz require design verification.
• Electrical Performance: Gain of 13.3dB and noise figure of 0.9dB are within typical design tolerances relative to the original 13.6dB gain and 0.7dB noise figure.
• Compliance Status: Both components are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and handling requirements.
• Active Product Status: The substitute is an active product with confirmed inventory availability, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the BGA7L1N6E6327XTSA1 be used as a direct replacement for the BGS8L5UKZ?

A: The BGA7L1N6E6327XTSA1 is mechanically and electrically compatible for most LTE applications. The primary consideration is frequency coverage: the substitute begins at 728MHz rather than 703MHz. Applications requiring operation below 728MHz require circuit-level verification before substitution.

Q: What are the key differences between these two parts?

A: The main differences are manufacturer (NXP vs. Infineon), frequency lower limit (703MHz vs. 728MHz), gain (13.6dB vs. 13.3dB), and noise figure (0.7dB vs. 0.9dB). Both share identical package type, surface mount configuration, and compliance certifications.

Q: Are there any supply voltage or current considerations for substitution?

A: The substitute specifies 1.5V to 3.3V supply voltage and 4.4mA supply current. The original part does not specify these parameters. Verify that the existing power delivery design accommodates these specifications before implementation.

Q: Does the package change affect PCB layout?

A: No. Both components use the 6-XFDFN package, requiring no PCB layout modifications. Thermal and mechanical mounting characteristics remain equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the BGS8L5UKZ and BGA7L1N6E6327XTSA1 are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring equivalent environmental and handling requirements.
