IC RF Switch SP6T 40GHz R574803605

Part Overview

The R574803605 is an RF Switch IC with SP6T (single-pole, six-throw) topology designed for general-purpose applications operating across the 0Hz to 40GHz frequency range. This component is manufactured by Radiall USA, Inc. and is currently in active product status with 703 units available in bulk packaging. The SP6T configuration enables selection among six independent RF paths, making it suitable for multi-channel RF signal routing applications requiring 50-ohm impedance matching and high-frequency performance.

Substitute parts are necessary when specific circuit requirements demand alternative switch topologies (SP3T or SP4T configurations), when inventory constraints limit availability of the primary part number, or when design modifications require different throw counts while maintaining compatibility across core electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R574803605 is determined by strict adherence to the following core electrical and mechanical parameters:

Critical Matching Parameters:

• Frequency Range: 0Hz ~ 40GHz (all substitutes must support full range)
• Impedance: 50Ohm (mandatory for RF path compatibility)
• Isolation: 50dB minimum (signal separation requirement)
• Insertion Loss: 1.1dB maximum (signal attenuation limit)
• Voltage Supply: 24V ~ 30V (power delivery compatibility)
• Operating Temperature: -40°C ~ 85°C (thermal operating envelope)
• Package Type: Module (physical form factor)
• Manufacturer: Radiall USA, Inc. (design consistency)

Variable Parameter (Allows Substitution):

• Circuit Configuration: SP3T, SP4T, or SP6T (throw count variation permitted based on application requirements)

The three substitute parts listed below maintain identical electrical performance specifications across all critical parameters while offering alternative switch topologies. Selection among these substitutes depends solely on the required number of RF paths (throws) for the specific application circuit design.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status with Radiall USA, Inc., ensuring continued design support and manufacturing availability. Selection criteria are based on circuit topology requirements and compliance certifications:

R573803320 (SP3T Configuration): Select this substitute when the application circuit requires three independent RF paths. This part maintains identical electrical performance across all critical parameters and is suitable for designs with reduced throw count requirements.

R573883400 (SP4T Configuration): Select this substitute when the application circuit requires four independent RF paths. This part carries ROHS3 compliance certification and is suitable for designs requiring intermediate throw count between SP3T and SP6T configurations.

R573883600 (SP6T Configuration): Select this substitute as a direct replacement for the R574803605 when maintaining the six-throw topology. This part carries ROHS3 compliance certification and provides identical electrical and mechanical specifications. Use this part number when inventory of the primary part number is constrained.

All substitute parts operate within the identical frequency range (0Hz ~ 40GHz), impedance (50Ohm), isolation (50dB minimum), insertion loss (1.1dB maximum), voltage supply range (24V ~ 30V), and operating temperature range (-40°C ~ 85°C). Physical form factor remains consistent across all options as Module-type packages.

Frequently Asked Questions (FAQ)

Q: Can R573803320 (SP3T) be used as a direct replacement for R574803605 (SP6T)?

A: R573803320 is electrically compatible across all critical RF parameters (frequency range, impedance, isolation, insertion loss, voltage supply, and operating temperature). However, it provides only three RF paths instead of six. Use this substitute only if your circuit design requires three or fewer independent RF paths.

Q: What is the difference between R573883600 and R574803605?

A: Both parts are SP6T RF switches with identical electrical specifications (0Hz ~ 40GHz frequency range, 50Ohm impedance, 50dB isolation, 1.1dB insertion loss, 24V ~ 30V supply, -40°C ~ 85°C operating temperature). R573883600 carries ROHS3 compliance certification. Both are suitable for direct substitution based on topology and compliance requirements.

Q: Are all substitute parts available in the same Module package type?

A: Yes. R573803320, R573883400, and R573883600 are all supplied in Module package type, identical to the R574803605. All parts are available in bulk packaging.

Q: What determines whether I should select SP3T, SP4T, or SP6T?

A: The selection is determined by the number of independent RF paths required in your circuit design. SP3T provides three paths, SP4T provides four paths, and SP6T provides six paths. All three topologies maintain identical electrical performance across frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature specifications.

Q: Do all substitute parts meet the same electrical specifications?

A: Yes. All substitute parts (R573803320, R573883400, R573883600) meet identical specifications for frequency range (0Hz ~ 40GHz), impedance (50Ohm), isolation (50dB minimum), insertion loss (1.1dB maximum), test frequency (40GHz), voltage supply (24V ~ 30V), and operating temperature (-40°C ~ 85°C).

Q: Which substitute part has the highest inventory availability?

A: R573883400 (SP4T) has the highest inventory with 1,044 pieces available. R573883600 (SP6T) has 957 pieces, and R573803320 (SP3T) has 734 pieces in stock.
