Engineering Selection Recommendations
For Direct Replacement (SP6T Topology Required):
The following active SP6T RF switch ICs provide complete electrical and mechanical equivalence to the obsolete R574453605:
- R573403600: Active status with ROHS3 compliance. Inventory: 1004 units.
- R573403610: Active status with ROHS3 compliance. Inventory: 681 units.
- R573403620: Active status with ROHS3 compliance. Inventory: 781 units.
These three parts are recommended for new designs and production support due to confirmed ROHS3 compliance certification.
Alternative SP6T options include R573403605, R573403610LP, and R573403615, which are active but lack specified RoHS compliance documentation.
For Reduced-Throw Applications (SP5T Topology):
When circuit design permits SP5T functionality, the following active alternatives are available:
- R573403510: Active status with ROHS3 compliance. Inventory: 716 units.
- R573403520: Active status with ROHS3 compliance. Inventory: 955 units.
- R573403540: Active status with ROHS3 compliance. Inventory: 722 units.
SP5T parts maintain all electrical performance parameters (frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature) while reducing throw count from six to five positions.
Frequently Asked Questions (FAQ)
Q: Can R573403600 directly replace R574453605 in existing designs?
A: Yes. R573403600 is an active SP6T RF switch IC with identical electrical parameters: 0Hz to 18GHz frequency range, 50Ohm impedance, 60dB minimum isolation, 0.5dB maximum insertion loss, 24V to 30V supply voltage, and -40°C to 85°C operating temperature. Both are housed in module packages. ROHS3 compliance is documented for R573403600.
Q: What is the difference between SP6T and SP5T configurations?
A: SP6T (single-pole six-throw) provides six selectable output positions, while SP5T (single-pole five-throw) provides five selectable output positions. All other electrical parameters remain identical. SP5T parts are applicable only in applications where five throw positions satisfy circuit requirements.
Q: Are all substitute parts available in the same packaging?
A: Yes. All substitute parts listed are supplied in module packages matching the original R574453605 package type. Packaging format is specified as bulk for all active alternatives.
Q: Which substitute parts have RoHS compliance certification?
A: The following parts carry ROHS3 compliance documentation: R573403600, R573403610, R573403620 (SP6T variants) and R573403510, R573403520, R573403540 (SP5T variants). Parts R573403605, R573403610LP, and R573403615 do not have specified RoHS compliance status in available documentation.
Q: Can I use an SP5T part in a design originally specified for SP6T?
A: SP5T substitution is applicable only if the circuit design requires a maximum of five throw positions. The electrical performance parameters are equivalent, but the reduced throw count limits functionality. Circuit redesign may be necessary to accommodate SP5T topology.
Q: What inventory levels are available for immediate procurement?
A: Current inventory for SP6T direct replacements includes: R573403600 (1004 units), R573403610 (681 units), and R573403620 (781 units). For SP5T alternatives: R573403510 (716 units), R573403520 (955 units), and R573403540 (722 units).
Q: Are there any differences in electrical performance between the SP6T substitute options?
A: No. All SP6T substitute parts (R573403600, R573403605, R573403610, R573403610LP, R573403615, R573403620) maintain identical electrical specifications: 0Hz to 18GHz frequency range, 50Ohm impedance, 60dB minimum isolation, 0.5dB maximum insertion loss, 24V to 30V supply voltage, and -40°C to 85°C operating temperature range.
