Substitute Part Grouping Explanation

Substitution of the PE42641MLBC-Z is determined by strict equivalence across the following critical parameters:

• Circuit Topology: SP4T configuration required for pin-compatible replacement
• Frequency Range: 100MHz ~ 3GHz operational band
• Impedance: 50Ohm characteristic impedance
• Supply Voltage: 2.65V ~ 2.85V compatibility
• Package: 16-WFQFN Exposed Pad surface mount form factor
• Operating Temperature Range: -40°C ~ 85°C
• IIP3 Performance: 68dBm linearity specification

The PE42641MLBD-Z meets all substitution criteria as a direct equivalent from the same manufacturer, with identical circuit topology, frequency range, impedance, supply voltage, package configuration, and temperature range. This part is classified as Active product status, providing long-term availability for design transitions.
