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

Mechanical and Packaging Equivalence Criteria:

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

Compliance Equivalence Criteria:

• RoHS3 compliance status must be maintained

The substitute part R577413000 meets all electrical, mechanical, and compliance parameters specified for the R577433102, establishing direct parametric equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the R577433102 and R577413000 are active products manufactured by Radiall USA, Inc., with identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on inventory availability and procurement requirements rather than technical performance differentiation.

The R577433102 maintains higher current inventory (1022 units) compared to R577413000 (739 units). Both parts satisfy ROHS3 compliance requirements and operate across the specified temperature and voltage ranges without performance degradation.

For applications requiring DPDT RF switching at frequencies up to 18GHz with 50Ohm impedance, either part number provides equivalent functional performance and can be selected based on supply chain considerations and delivery timelines.

Frequently Asked Questions (FAQ)

Q: Can R577413000 be used as a direct replacement for R577433102?

A: Yes. Both parts are manufactured by Radiall USA, Inc., and share identical electrical parameters including DPDT topology, 0Hz ~ 18GHz frequency range, 50Ohm impedance, 60dB isolation, 0.5dB insertion loss, 24V ~ 30V supply voltage, and -40°C ~ 85°C operating temperature range. Both are packaged as modules with SMA connectors and maintain ROHS3 compliance.

Q: Are there any differences in package configuration between these parts?

A: Both parts use identical module packaging with SMA connectors. No package reconfiguration or PCB layout modifications are required when substituting between these part numbers.

Q: What is the basis for substitution between R577433102 and R577413000?

A: Substitution is based on parametric equivalence across all critical electrical specifications (circuit topology, frequency range, impedance, isolation, insertion loss, supply voltage, operating temperature), mechanical packaging (module with SMA connectors), and compliance certifications (ROHS3). Both parts are active products from the same manufacturer.

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

A: Both parts maintain ROHS3 compliance status. The R577413000 includes additional documentation of REACH Affected status and ECCN EAR99 classification. These designations do not affect electrical or mechanical compatibility.

Q: Which part should be selected for new designs?

A: Either part number is suitable for new designs. Selection should be based on current inventory availability and procurement lead times. Both parts provide identical RF performance and reliability characteristics.
