R573813625 RF Switch IC SP6T 40GHz Equivalent & Substitute Parts

Part Overview

The R573813625 is an RF Switch IC featuring a single-pole six-throw (SP6T) topology designed for general-purpose RF switching applications. This active product operates across a frequency range of 0Hz to 40GHz with 50-ohm impedance and is manufactured by Radiall USA, Inc. The part is supplied in module packaging and is ROHS3 compliant. Substitute parts are identified to provide alternative configurations when the SP6T topology is not required or when alternative switch throw counts are acceptable for system design requirements.

Engineering Selection Recommendations

R573883600 (SP6T Configuration) This part is the direct equivalent to the R573813625, offering identical circuit configuration (SP6T) with all electrical and mechanical parameters matching. Both parts are ROHS3 compliant and active products. Selection of R573883600 is appropriate when direct functional replacement is required.

R573883400 (SP4T Configuration) This part provides reduced switch throw count (SP4T versus SP6T) while maintaining all other electrical parameters. ROHS3 compliance and active product status are confirmed. Selection is appropriate for applications requiring four selectable output paths instead of six.

R573803320 (SP3T Configuration) This part provides the minimum switch throw count (SP3T) among the substitute options while maintaining all electrical parameters. Product status is active. Selection is appropriate for applications requiring three selectable output paths. RoHS compliance status is not specified for this part.

All substitute parts operate within identical frequency, impedance, isolation, insertion loss, supply voltage, and temperature ranges as the main part. Selection between configurations depends solely on the required number of switch throw paths for the application.

Frequently Asked Questions (FAQ)

Q: Can R573883600 be used as a direct replacement for R573813625? A: Yes. Both parts feature SP6T configuration with identical electrical specifications including frequency range (0Hz ~ 40GHz), impedance (50Ohm), isolation (50dB minimum), insertion loss (1.1dB maximum), supply voltage (24V ~ 30V), and operating temperature range (-40°C ~ 85°C). Both are ROHS3 compliant and active products.

Q: What is the primary difference between the substitute parts? A: The substitute parts differ in circuit configuration (switch throw count). R573803320 is SP3T (3 throws), R573883400 is SP4T (4 throws), and R573883600 is SP6T (6 throws). All other electrical and mechanical parameters remain identical.

Q: Can I use R573803320 or R573883400 if my application only requires fewer switch paths? A: Circuit configuration selection depends on application requirements. If your system design requires only three or four selectable output paths, R573803320 (SP3T) or R573883400 (SP4T) can be used. However, if your design requires six selectable paths, only R573813625 or R573883600 (both SP6T) are suitable.

Q: Are all substitute parts available in the same module package? A: Yes. All parts listed are supplied in module packaging, ensuring mechanical compatibility in existing designs.

Q: What is the RoHS compliance status for all substitute parts? A: R573813625, R573883400, and R573883600 are ROHS3 compliant. RoHS compliance status for R573803320 is not specified in the provided data.

Q: Do all parts operate at the same supply voltage? A: Yes. All parts operate within the 24V ~ 30V supply voltage range and the -40°C ~ 85°C operating temperature range.

Q: What frequency range do these RF switches support? A: All parts support the identical frequency range of 0Hz ~ 40GHz with 50-ohm impedance and 50dB minimum isolation at 40GHz test frequency.
