Substitute parts for the R573803680 are identified based on strict parameter equivalence within the Radiall SPnT RF switch family. The primary substitution criteria are:

Maintained Parameters (Required for Substitution):

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

Engineering Selection Recommendations

R573803680 (SP6T) Primary Application: The R573803680 is selected for applications requiring six independent switching paths within a single-pole configuration. This part maintains active product status with full ROHS3 compliance and represents the baseline specification for this analysis.

R573883600 (SP6T) Direct Equivalent: The R573883600 provides identical circuit topology (SP6T) with all electrical parameters matching the R573803680. Both parts maintain ROHS3 compliance and active product status. This part is suitable for direct substitution without circuit redesign. Current inventory of 957 units supports availability requirements.

R573883400 (SP4T) Reduced-Path Alternative: The R573883400 operates with four switching paths instead of six. All RF performance parameters remain equivalent. This part is suitable for applications where circuit design accommodates four-throw switching. ROHS3 compliance is maintained. Inventory of 1044 units is available.

R573803320 (SP3T) Minimal-Path Alternative: The R573803320 provides three switching paths with all RF performance parameters equivalent to the main part. This configuration is suitable for applications requiring only three switching paths. RoHS compliance status is not specified for this part. Inventory of 734 units is available.

Frequently Asked Questions (FAQ)

Q: Can R573883600 replace R573803680 without circuit modification?

A: Yes. Both parts feature identical SP6T topology with matching electrical specifications across frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature. Both maintain ROHS3 compliance and active product status.

Q: What is the primary difference between R573803680 and R573883400?

A: The circuit configuration differs: R573803680 is SP6T (six throw paths) while R573883400 is SP4T (four throw paths). All RF performance parameters are equivalent. Substitution requires circuit design compatibility with four switching paths instead of six.

Q: Can lower throw-count parts substitute for the SP6T configuration?

A: Lower throw-count parts (SP3T or SP4T) can substitute only when application circuit design accommodates the reduced number of switching paths. The RF performance parameters remain equivalent across all configurations.

Q: Are all substitute parts ROHS3 compliant?

A: R573803680, R573883400, and R573883600 are specified as ROHS3 compliant. RoHS compliance status is not specified for R573803320.

Q: What is the frequency operating range for all substitute parts?

A: All parts operate across 0Hz to 40GHz with 40GHz test frequency specification.

Q: Do all parts require identical supply voltage?

A: Yes. All parts require 24V to 30V supply voltage with identical operating temperature range of -40°C to 85°C.

Q: What packaging format is used for all substitute parts?

A: All parts are supplied in module packaging format with bulk packaging configuration.
