Circuit Configuration Consideration: The R574482685 employs SP6T topology. Substitute parts are grouped into two categories based on circuit configuration:

SP3T Configuration (R573412300, R573412305, R573412320, R573412325, R573412335, R573412380): These parts maintain all electrical parameters identical to the main part but feature reduced throw count (3 throws versus 6 throws). SP3T configuration represents a functional reduction in switching capability.
SP4T Configuration (R573412400, R573412405, R573412420, R573412425): These parts maintain all electrical parameters identical to the main part but feature intermediate throw count (4 throws versus 6 throws). SP4T configuration represents a functional reduction in switching capability.

Engineering Selection Recommendations

Product Status Consideration: The R574482685 carries obsolete status, making it unavailable for new procurement. All listed substitute parts maintain active product status, ensuring supply chain continuity and manufacturer support.

RoHS Compliance: Parts R573412320, R573412325, R573412335, R573412380, R573412420, and R573412425 carry ROHS3 compliance certification. Parts R573412300, R573412305, R573412400, and R573412405 do not specify RoHS status. Design requirements for environmental compliance should guide selection among compliant alternatives.

Circuit Configuration Selection: Selection between SP3T, SP4T, and SP6T configurations depends on application switching requirements. The SP3T variants (R573412300, R573412305, R573412320, R573412325, R573412335, R573412380) provide three throw positions. The SP4T variants (R573412400, R573412405, R573412420, R573412425) provide four throw positions. Applications requiring six throw positions cannot be directly substituted with reduced-throw configurations without circuit redesign.

Electrical Parameter Equivalence: All substitute parts maintain identical electrical performance across frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature specifications. Direct electrical substitution is supported for applications where circuit topology permits reduced throw count.
