IC RF SWITCH SP3T 3GHZ R574332345

Part Overview

The R574332345 is a general-purpose RF switch IC with SP3T (single-pole, three-throw) topology designed for operation up to 3GHz. This component features 50-ohm impedance, 80dB minimum isolation, and 0.2dB maximum insertion loss. The part is currently classified as obsolete, necessitating identification of active substitute components that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Engineering Selection Recommendations

The R574332345 is classified as obsolete and should be replaced with an active substitute for new designs and ongoing system support. Three parametric equivalents are available, all manufactured by Radiall USA, Inc., with identical electrical and mechanical specifications.

R574002325 is available with 674 units in stock and carries ROHS3 compliance certification.

R574012300 is available with 706 units in stock and meets standard moisture sensitivity requirements.

R574092325 is available with 976 units in stock and carries ROHS3 compliance certification, offering the highest current inventory level.

All three substitutes are functionally interchangeable with the obsolete R574332345 based on matching electrical performance parameters, frequency response, impedance characteristics, and operating environmental specifications. Selection among the three active alternatives should be based on inventory availability, compliance requirements for the target application, and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can the R574002325, R574012300, or R574092325 be used as direct replacements for the obsolete R574332345?

A: Yes. All three substitute parts maintain identical electrical specifications including SP3T topology, 0Hz to 3GHz frequency range, 50-ohm impedance, 80dB isolation, 0.2dB insertion loss, 10.2V to 13V supply voltage, and -40°C to 85°C operating temperature range. The substitutes are functionally equivalent for all applications where the R574332345 was specified.

Q: What is the difference between the three substitute parts?

A: The three substitutes are parametrically identical. Differences exist only in product status (all active), inventory levels, and compliance certifications. R574002325 and R574092325 carry ROHS3 compliance, while R574012300 does not list this certification. Inventory quantities are 674, 706, and 976 units respectively.

Q: Are there any packaging differences between the main part and the substitutes?

A: The main part R574332345 specifies module packaging. All three substitutes also use module packaging. The substitutes are supplied in bulk packaging configuration, which is standard for active production parts.

Q: Which substitute should be selected for new designs?

A: Selection should be based on application requirements. For applications requiring ROHS3 compliance, R574002325 or R574092325 are appropriate. For applications without specific compliance mandates, all three substitutes are equivalent. R574092325 offers the highest inventory availability.

Q: Are the supply voltage and operating temperature ranges identical across all parts?

A: Yes. All parts, including the obsolete main part and all three substitutes, operate within 10.2V to 13V supply voltage and -40°C to 85°C temperature range specifications.
