Key Parameters

Substitute Part Grouping Explanation

Substitution of the BGS8M4UKZ is determined by the following critical parameters:

• Frequency coverage: The substitute must operate within or encompass the 1.8GHz to 2.2GHz band
• Gain and noise figure: Performance metrics must be compatible with the application requirements
• Supply voltage and current: Operating conditions must align with system power delivery constraints
• Package and mounting: Surface mount compatibility and pin configuration must support PCB integration
• Regulatory compliance: RoHS3 and REACH status must be maintained

The BGS8H5UKZ qualifies as a manufacturer-recommended substitute based on overlapping frequency coverage (1.425GHz to 2.69GHz encompasses the 1.8GHz to 2.2GHz band), compatible surface mount technology, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The BGS8H5UKZ is designated as the manufacturer-recommended substitute for the obsolete BGS8M4UKZ. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The BGS8H5UKZ offers extended frequency coverage (1.425GHz to 2.69GHz) that encompasses the original part's operating band, with superior noise figure performance (0.75dB versus 0.8dB). The gain differential (13.1dB versus 16.6dB) must be evaluated against specific application requirements. The package transition from 6-WLCSP to 6-XFDFN requires PCB layout modification. Active product status of the BGS8H5UKZ ensures long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Why is the BGS8M4UKZ classified as obsolete? A: The BGS8M4UKZ has reached end-of-life status with NXP USA Inc. The BGS8H5UKZ represents the active replacement offering equivalent or superior performance characteristics within the required frequency band.

Q: Does the BGS8H5UKZ cover the 1.8GHz to 2.2GHz frequency range? A: Yes. The BGS8H5UKZ operates across 1.425GHz to 2.69GHz, which fully encompasses the 1.8GHz to 2.2GHz band of the original part.

Q: What is the gain difference between these parts? A: The BGS8M4UKZ provides 16.6dB gain, while the BGS8H5UKZ provides 13.1dB gain. This 3.5dB difference must be evaluated against application-specific gain requirements and system design margins.

Q: Are the packages compatible? A: No. The BGS8M4UKZ uses 6-WLCSP (0.65x0.44mm) packaging, while the BGS8H5UKZ uses 6-XFDFN (1.1x0.7mm) packaging. PCB layout and footprint redesign is required for substitution.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both the BGS8M4UKZ and BGS8H5UKZ are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8542.33.0001).

Q: Which part should be selected for new designs? A: The BGS8H5UKZ should be selected for new designs due to its active product status, ensuring availability and long-term supply chain support.
