Key Parameters

Substitute Part Grouping Explanation

Substitution of RF Switch IC components is determined by electrical and mechanical parameter compatibility. The primary substitution criteria for the R573803620 SP6T switch are:

Critical Parameters for Substitution:

• Frequency Range: 0Hz ~ 40GHz (all substitutes match)
• Impedance: 50Ohm (all substitutes match)
• Isolation: 50dB minimum (all substitutes match)
• Insertion Loss: 1.1dB maximum (all substitutes match)
• Voltage Supply: 24V ~ 30V (all substitutes match)
• Operating Temperature: -40°C ~ 85°C (all substitutes match)
• Package / Case: Module (all substitutes match)
• RF Type: General Purpose (all substitutes match)

Circuit Topology Consideration: The R573803620 is an SP6T (single-pole six-throw) configuration. Substitute parts include both identical SP6T topology (R573883600) and alternative topologies (R573803320 as SP3T and R573883400 as SP4T). Alternative topologies are listed as substitutes where circuit design permits reduced throw count, subject to application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Topology): R573883600 is a direct equivalent to R573803620, both featuring SP6T topology with identical electrical specifications. Both parts are ROHS3 compliant and active products. This part is suitable for direct substitution in applications requiring six-throw switching capability.

Alternative Topology Substitutes: R573803320 (SP3T) and R573883400 (SP4T) are listed as substitutes where circuit design accommodates reduced throw count. These parts maintain all critical electrical parameters including frequency range, impedance, isolation, insertion loss, voltage supply, and operating temperature. Both alternative topologies are active products with ROHS3 compliance (R573883400 confirmed; R573803320 compliance not specified in provided data).

Compliance and Availability: All substitute parts are active products from Radiall USA, Inc. with confirmed inventory availability. R573883600 and R573883400 carry explicit ROHS3 compliance certification. Selection should be based on circuit topology requirements and compliance documentation needs for the application.

Frequently Asked Questions (FAQ)

Q: Can R573883600 replace R573803620 in all applications? A: R573883600 is a direct equivalent with identical SP6T topology and all electrical specifications matching the R573803620. Both are ROHS3 compliant active products. Substitution is valid where the application circuit design accepts this part number.

Q: What is the difference between R573803320 and R573883400 as substitutes? A: R573803320 is an SP3T (three-throw) configuration, while R573883400 is an SP4T (four-throw) configuration. Both maintain identical electrical performance across frequency range, impedance, isolation, insertion loss, voltage supply, and operating temperature. Selection depends on the number of switch positions required by the application circuit.

Q: Are all substitute parts ROHS3 compliant? A: R573883600 and R573883400 are explicitly ROHS3 compliant. R573803320 compliance status is not specified in the provided technical data.

Q: Do all substitute parts operate at the same frequency range? A: All substitute parts operate across 0Hz to 40GHz with identical 50-ohm impedance and 50dB minimum isolation, tested at 40GHz.

Q: What is the voltage supply requirement for substitute parts? A: All substitute parts require 24V to 30V supply voltage, matching the R573803620 specification.

Q: Are substitute parts available in the same module package? A: All substitute parts are supplied in module packaging, consistent with the R573803620.

Q: Can I use R573803320 (SP3T) if my circuit requires six throw positions? A: No. R573803320 provides only three throw positions. Use R573883600 or R573803620 for six-throw applications.

Q: What is the insertion loss specification for all parts? A: All parts specify a maximum insertion loss of 1.1dB at the 40GHz test frequency.
