Engineering Selection Recommendations

The R591362440 is a direct parametric equivalent to the R591302425. Both components are manufactured by Radiall USA, Inc., and share identical electrical specifications, mechanical packaging, and compliance certifications.

Selection Criteria:

Both parts are in active production status and maintain ROHS3 compliance. The R591302425 has 842 units in current inventory, while the R591362440 has 786 units available. Either part can be selected based on supply availability and procurement lead time requirements.

The R591362440 carries additional regulatory documentation including REACH Affected status, ECCN classification (EAR99), and HTSUS code (8543.70.9860), which may be relevant for international distribution or export compliance requirements. The R591302425 does not specify these additional regulatory parameters in the provided data.

Both components are suitable for direct substitution in SP4T RF switching applications requiring 50-ohm impedance, 6GHz frequency operation, and module-level integration with SMA connectors.

Frequently Asked Questions (FAQ)

Q: Can the R591362440 be used as a direct replacement for the R591302425?

A: Yes. Both components are parametrically identical across all critical electrical and mechanical specifications, including circuit topology (SP4T), frequency range (0Hz ~ 6GHz), impedance (50Ohm), isolation (70dB minimum), insertion loss (0.3dB maximum), supply voltage (10.2V ~ 13V), operating temperature (-40°C ~ 85°C), and package format (Module with SMA connectors). No circuit modification is required.

Q: Are there any differences in compliance or regulatory status between these parts?

A: Both parts are ROHS3 compliant. The R591362440 includes additional regulatory documentation specifying REACH Affected status, ECCN classification (EAR99), and HTSUS code (8543.70.9860). The R591302425 does not provide these additional regulatory parameters. If international distribution or export compliance documentation is required, the R591362440 may provide more complete regulatory traceability.

Q: What is the significance of the SP4T circuit configuration?

A: SP4T denotes a Single Pole, Four Throw switch topology, meaning the component can route a single RF input signal to any one of four output paths. This configuration is essential for multi-channel RF selection applications. Both substitute parts maintain this identical topology.

Q: Are the SMA connectors identical on both parts?

A: Yes. Both the R591302425 and R591362440 are specified with Module package format and SMA connectors. The mechanical interface and connector type are identical, ensuring direct physical compatibility in existing circuit board layouts.

Q: What is the operating frequency range, and does it apply to both parts?

A: Both parts operate across 0Hz to 6GHz, with performance specifications tested at 6GHz. This frequency range encompasses DC through microwave applications, making these components suitable for broadband RF switching applications.

Q: What supply voltage is required for operation?

A: Both parts require a supply voltage range of 10.2V to 13V. This specification must be met exactly; operation outside this range is not supported by either component.

Q: What is the insertion loss specification, and why is it important?

A: Both parts specify a maximum insertion loss of 0.3dB at the test frequency of 6GHz. Insertion loss represents signal attenuation through the switch; lower values indicate better signal preservation. This specification is identical for both components.

Q: What is the isolation specification, and what does it indicate?

A: Both parts specify a minimum isolation of 70dB. Isolation measures the attenuation between the selected output path and non-selected paths, indicating how effectively the switch prevents signal leakage between channels. This specification is identical for both components.
