R577433017 RF Switch IC DPDT 18GHz Equivalent & Substitute Parts

Part Overview

The R577433017 is an RF Switch IC with DPDT (Double Pole Double Throw) topology designed for general-purpose switching applications across a frequency range of 0Hz to 18GHz. This component operates at 50 Ohm impedance with a supply voltage range of 24V to 30V and is housed in a module package with SMA connectors. The part maintains an active product status with 1064 units currently in stock. Substitute parts are identified when inventory constraints, supply chain disruptions, or procurement requirements necessitate alternative sourcing while maintaining equivalent electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution of the R577433017 is based on strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Circuit topology must be DPDT
• Frequency range must cover 0Hz to 18GHz minimum
• Impedance must be 50 Ohm
• Isolation specification must meet or exceed 60dB at minimum
• Insertion loss must not exceed 0.5dB maximum
• Supply voltage range must accommodate 24V to 30V operation
• Operating temperature range must span -40°C to 85°C

Mechanical & Interface Criteria:

• Package type must be Module with SMA Connectors
• RF Type classification must be General Purpose

The substitute part R577413000 meets all specified electrical and mechanical parameters, enabling direct functional equivalence in applications requiring DPDT RF switching at frequencies up to 18GHz.

Parameter Comparison

Engineering Selection Recommendations

Both the R577433017 and R577413000 are active products manufactured by Radiall USA, Inc., with identical electrical and mechanical specifications. The substitute part R577413000 carries ROHS3 compliance certification and documented REACH status, providing additional regulatory compliance documentation for applications requiring environmental and hazardous substance compliance verification.

Selection between these parts should be based on:

1. Inventory Availability: R577433017 has 1064 units in stock; R577413000 has 739 units in stock.
2. Regulatory Requirements: Applications requiring explicit ROHS3 compliance documentation should specify R577413000.
3. Supply Chain Continuity: Either part provides equivalent performance for DPDT RF switching applications operating within the specified frequency, impedance, and temperature parameters.

Both parts are suitable for direct substitution in circuit designs without modification to electrical or mechanical interfaces.

Frequently Asked Questions (FAQ)

Q: Can R577413000 be used as a direct replacement for R577433017?

A: Yes. Both parts are DPDT RF switches with identical electrical specifications (0Hz to 18GHz frequency range, 50 Ohm impedance, 60dB isolation minimum, 0.5dB insertion loss maximum) and identical mechanical packaging (Module with SMA Connectors). No circuit modifications are required.

Q: What are the key differences between these two parts?

A: The primary differences are inventory levels and regulatory documentation. R577413000 includes ROHS3 compliance certification and documented REACH status, while R577433017 does not specify these certifications. Electrical and mechanical performance are identical.

Q: Are the SMA connector interfaces identical between both parts?

A: Yes. Both parts use Module packaging with SMA Connectors as the interface standard. Physical and electrical connector compatibility is identical.

Q: What supply voltage is required for operation?

A: Both parts operate with a supply voltage range of 24V to 30V. Design circuits must provide voltage regulation within this range.

Q: What is the maximum frequency these switches support?

A: Both parts support operation across the frequency range of 0Hz to 18GHz, with test frequency specified at 18GHz.

Q: Can these parts be used in temperature-sensitive applications?

A: Yes. Both parts are rated for operating temperatures from -40°C to 85°C, suitable for industrial and extended temperature range applications.

Q: Which part should be selected for new designs?

A: For new designs requiring regulatory compliance documentation, R577413000 is recommended due to explicit ROHS3 and REACH status. For applications without specific compliance requirements, either part provides equivalent performance.
