Engineering Selection Recommendations

Direct Equivalents (SP6T Configuration):

The following parts provide direct functional equivalence to the R574313615 with identical circuit topology:

R573513620: Active product status with ROHS3 compliance certification
R573513625: Active product status with ROHS3 compliance certification
R573533600: Active product status

These three parts maintain the SP6T configuration and all electrical parameters identical to the obsolete R574313615. Selection among these direct equivalents should be based on compliance requirements and inventory availability.

Parametric Equivalents (Reduced Throw Count):

The following parts maintain all electrical specifications but with reduced circuit throw configurations:

SP4T Configuration: R573503400, R573523410, R573533400
SP3T Configuration: R573523310, R574003300, R574003335, R574003345

These parts are suitable for applications where the reduced number of throw positions meets functional requirements. R574003345 provides ROHS3 compliance certification within the SP3T category.

Compliance Considerations:

For applications requiring ROHS3 compliance, the following parts are certified: R573513620, R573513625, and R574003345. All other substitute parts do not specify RoHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can R573513620 or R573513625 be used as direct replacements for R574313615?

A: Yes. Both R573513620 and R573513625 maintain identical electrical specifications including frequency range (0Hz ~ 3GHz), impedance (50 Ohm), isolation (80dB minimum), insertion loss (0.2dB maximum), voltage supply (24V ~ 30V), and operating temperature range (-40°C ~ 85°C). Both are active products with ROHS3 compliance certification.

Q: What is the difference between SP6T, SP4T, and SP3T configurations?

A: The designations refer to circuit throw count. SP6T provides six throw positions, SP4T provides four throw positions, and SP3T provides three throw positions. All configurations within this product family maintain identical RF performance characteristics at 3GHz test frequency. Selection depends on application requirements for the number of available switch positions.

Q: Are all substitute parts manufactured by the same company?

A: Yes. All substitute parts listed are manufactured by Radiall USA, Inc., the same manufacturer as the original R574313615.

Q: What packaging is used for these RF switch ICs?

A: All parts in this family use Module packaging. No alternative package types are available within the provided substitute list.

Q: Why is the R574313615 classified as obsolete?

A: The R574313615 is listed as obsolete by the manufacturer. Active equivalent products are available with identical electrical performance and improved compliance certifications, making them suitable for both replacement applications and new designs.

Q: Can I use an SP4T part if my application originally used SP6T?

A: SP4T parts provide four switch positions instead of six. This substitution is only valid if your application requires four or fewer switch positions. The electrical performance characteristics remain identical across all configurations.

Q: Which substitute part offers the best compliance certification?

A: R573513620, R573513625, and R574003345 all carry ROHS3 compliance certification. R573513620 and R573513625 maintain the SP6T configuration, while R574003345 uses SP3T configuration.

Q: Is there a difference in electrical performance between the SP6T substitute options?

A: No. R573513620, R573513625, and R573533600 all maintain identical electrical specifications. All three are active products. R573513620 and R573513625 carry ROHS3 compliance certification, while R573533600 does not specify this certification.
