Substitute Part Grouping Explanation

Substitution eligibility for RF Switch IC components is determined by strict equivalence across electrical and mechanical parameters. The R577453017 accepts R577413000 as a parametric equivalent based on the following substitution criteria:

Electrical Parameter Equivalence:

• Identical DPDT circuit topology
• Matching frequency range specification (0Hz ~ 18GHz)
• Identical impedance rating (50Ohm)
• Equivalent isolation performance (60dB minimum)
• Equivalent insertion loss specification (0.5dB maximum)
• Identical supply voltage range (24V ~ 30V)
• Matching operating temperature range (-40°C ~ 85°C)

Mechanical Parameter Equivalence:

• Identical package configuration (Module with SMA Connectors)
• Compatible connector interface standards

Regulatory Equivalence:

• Both parts maintain ROHS3 compliance status
• Both parts carry Active product status

The substitute part R577413000 maintains full electrical and mechanical compatibility with the primary part R577453017, permitting direct substitution in circuit applications without design modification or performance degradation.
