Substitute Part Grouping Explanation

Substitute parts for the R574413630 are grouped based on strict electrical and mechanical parameter alignment within the SPnT RF switch family. The primary substitution criteria are:

Critical Parameters for Substitution:

Frequency Range: 0Hz ~ 18GHz (must match)
Impedance: 50Ohm (must match)
Isolation: 60dB minimum (must match)
Insertion Loss: 0.5dB maximum (must match)
Voltage Supply: 24V ~ 30V (must match)
Operating Temperature: -40°C ~ 85°C (must match)
Package Type: Module (must match)
RF Type: General Purpose (must match)

Circuit Configuration Consideration: Substitute parts are divided into two categories: SP6T equivalents (identical circuit topology) and SP5T alternatives (reduced throw configuration). SP6T substitutes provide direct functional equivalence. SP5T substitutes represent reduced-capability alternatives suitable only when application requirements permit operation with five throw positions instead of six.

All substitute parts listed are manufactured by Radiall USA, Inc., maintaining consistency within the SPnT series architecture.

Engineering Selection Recommendations

Direct Equivalents (SP6T Configuration):

The following parts provide direct functional equivalence to the R574413630 with identical SP6T circuit topology and all electrical parameters:

R573403600: Active product status with ROHS3 compliance. Highest inventory availability (1004 units).
R573403610: Active product status with ROHS3 compliance. Suitable for new designs requiring RoHS certification.
R573403620: Active product status with ROHS3 compliance. Recommended for applications requiring regulatory compliance documentation.

These three parts are preferred for direct replacement in applications where the six-throw configuration is functionally required.

Alternative Substitutes (SP6T Configuration):

R573403605: Active product status. Inventory availability of 871 units. RoHS status not specified.
R573403610LP: Active product status. Inventory availability of 677 units. RoHS status not specified.

Reduced-Capability Alternatives (SP5T Configuration):

The following parts operate with SP5T topology (five-throw instead of six-throw):

R573403510: Active product status with ROHS3 compliance. Inventory: 716 units.
R573403515: Active product status. Inventory: 953 units.

SP5T substitutes are applicable only when application circuit design can operate with five switch positions instead of six. All electrical parameters (frequency, impedance, isolation, insertion loss, voltage, temperature) remain identical to the original part.

Frequently Asked Questions (FAQ)

Q: Can SP5T parts directly replace the R574413630 SP6T configuration?

A: SP5T parts provide electrical parameter equivalence but offer reduced switching capability (five positions instead of six). Direct replacement is possible only if the application circuit design does not require the sixth throw position. Circuit redesign may be necessary to accommodate the reduced throw count.

Q: What is the primary difference between the SP6T and SP5T substitute options?

A: The circuit topology differs: SP6T provides six independent throw positions for signal routing, while SP5T provides five positions. All other electrical parameters—frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature—are identical between the two configurations.

Q: Are all substitute parts available in the same packaging as the original R574413630?

A: Yes. All substitute parts listed are supplied in Module package type, matching the original part's physical form factor. Packaging is specified as Bulk for all active substitutes.

Q: Which substitute parts carry RoHS3 compliance certification?

A: The following parts are explicitly marked as ROHS3 Compliant: R573403510, R573403520, R573403540, R573403600, R573403610, and R573403620. Parts without specified RoHS status should be verified against specific regulatory requirements before selection.

Q: What inventory levels are available for the recommended SP6T equivalents?

A: Current inventory for direct SP6T equivalents is as follows: R573403600 (1004 units), R573403610 (681 units), and R573403620 (781 units). All three parts maintain active product status with continuous availability.

Q: Can the R574413630 be used interchangeably with any of the listed substitutes in existing designs?

A: SP6T substitutes (R573403600, R573403605, R573403610, R573403610LP, R573403615, R573403620) provide direct interchangeability for the R574413630 in existing circuit designs. SP5T substitutes require circuit evaluation to confirm that five throw positions satisfy application requirements.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across the identical temperature range of -40°C to 85°C, matching the original R574413630 specification.

Q: Are there any differences in electrical performance between the SP6T substitute options?

A: No. All SP6T substitute parts maintain identical electrical specifications: 0Hz to 18GHz frequency range, 50-ohm impedance, 60dB minimum isolation, and 0.5dB maximum insertion loss at 18GHz test frequency.
