Substitute Part Grouping Explanation

Substitution eligibility for RF Switch IC components is determined by alignment across critical electrical and mechanical parameters. The primary substitution criteria include frequency range capability, impedance matching, isolation performance, insertion loss specifications, supply voltage compatibility, and operating temperature range. Parts are grouped as substitutes when they maintain identical or superior performance across these parameters while operating within the same frequency band and impedance standard.

The R573813615 SP6T topology serves as the reference configuration. Substitute parts R573883600 (SP6T) and R573883400 (SP4T) maintain full electrical parameter equivalence within the 0Hz to 40GHz frequency range. The R573803320 (SP3T) variant provides reduced switching throw capability while preserving all electrical performance metrics. All substitute parts share identical impedance (50Ohm), isolation (50dB minimum), insertion loss (1.1dB maximum), supply voltage (24V to 30V), and operating temperature specifications (-40°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status with Radiall USA, Inc. as the manufacturer. Selection between R573813615 and R573883600 is interchangeable for SP6T applications, as both parts are electrically and mechanically identical with ROHS3 compliance confirmed. The R573883400 SP4T variant provides equivalent electrical performance but reduces switching throw capability from six to four positions, suitable for applications requiring fewer RF path selections. The R573803320 SP3T variant further reduces throw capability to three positions while maintaining all electrical specifications and is suitable for simplified switching architectures.

Component selection should be based on the specific number of RF paths required by the circuit design. Where six independent RF paths are required, R573813615 or R573883600 are appropriate selections. Where four RF paths are sufficient, R573883400 provides equivalent electrical performance. Where three RF paths are sufficient, R573803320 provides equivalent electrical performance. All parts operate within identical frequency, impedance, isolation, insertion loss, supply voltage, and temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can R573883600 directly replace R573813615 in existing designs?

A: Yes. Both parts feature identical SP6T topology, frequency range (0Hz to 40GHz), impedance (50Ohm), isolation (50dB minimum), insertion loss (1.1dB maximum), supply voltage (24V to 30V), and operating temperature range (-40°C to 85°C). Both are ROHS3 compliant and packaged as modules.

Q: What is the primary difference between R573813615 and R573883400?

A: The primary difference is circuit topology. R573813615 is SP6T (six throw positions) while R573883400 is SP4T (four throw positions). All other electrical parameters including frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature are identical.

Q: Can R573803320 be used in place of R573813615?

A: R573803320 can be used only in applications requiring three or fewer RF path selections. The part is SP3T (three throw positions) compared to the SP6T topology of R573813615. All electrical performance parameters are identical. Circuit redesign may be required to accommodate the reduced number of switching positions.

Q: Are all substitute parts rated for the same frequency range?

A: Yes. All substitute parts (R573883600, R573883400, and R573803320) operate across the identical frequency range of 0Hz to 40GHz with test frequency at 40GHz.

Q: Do all substitute parts meet the same impedance and isolation specifications?

A: Yes. All parts maintain 50Ohm impedance, 50dB minimum isolation, and 1.1dB maximum insertion loss at the 40GHz test frequency.

Q: What are the supply voltage requirements for all substitute parts?

A: All parts require supply voltage between 24V and 30V. No voltage adjustment is required when substituting between these parts.

Q: Are there temperature rating differences between substitute parts?

A: No. All parts operate across the identical temperature range of -40°C to 85°C.

Q: What package type is used for all substitute parts?

A: All parts are packaged as modules. No package conversion is required when substituting between these parts.
