Substitute Part Grouping Explanation

Substitution of the R574332400 is determined by the following critical parameters:

Primary Substitution Criteria:

Circuit Configuration (SP4T or SP3T topology)
Frequency Range (0Hz ~ 3GHz capability)
Impedance (50 Ohm characteristic impedance)
Isolation Performance (80dB minimum)
Insertion Loss (0.2dB maximum)
Voltage Supply Range (10.2V ~ 13V)
Operating Temperature Range (-40°C ~ 85°C)
Package Type (Module form factor)

Substitution Logic:

SP4T Configuration substitutes maintain identical circuit topology to the R574332400 and provide direct functional replacement. These parts are R574002400, R574002420, R574002425, R574012405, R574032400, and R574032405.

SP3T Configuration substitutes (R574002325, R574012300, R574092325) provide reduced switching capability with three throw positions instead of four. These parts are suitable only when application requirements do not mandate four-position switching functionality.

All substitute parts operate within identical electrical specifications for frequency range, impedance, isolation, insertion loss, supply voltage, and temperature range. All substitute parts are classified as active products with current manufacturing status.

Engineering Selection Recommendations

Direct Replacement (SP4T Configuration):

For applications requiring identical SP4T switching functionality, the following active parts provide direct substitution:

R574002400: Active status, standard packaging, suitable for general replacement applications
R574002420: Active status, ROHS3 compliant, recommended for new designs with environmental compliance requirements
R574002425: Active status, ROHS3 compliant, highest inventory availability (1021 units), recommended for high-volume procurement
R574012405: Active status, suitable for applications with standard compliance requirements
R574032400: Active status, suitable for general replacement applications
R574032405: Active status, suitable for general replacement applications

Alternative Configuration (SP3T Configuration):

For applications where four-position switching is not required, SP3T alternatives provide functional substitution with reduced complexity:

R574002325: Active status, ROHS3 compliant, suitable for three-position switching requirements
R574012300: Active status, suitable for three-position switching requirements
R574092325: Active status, ROHS3 compliant, highest inventory availability among SP3T options (976 units)

Compliance Considerations:

Parts designated as ROHS3 compliant (R574002420, R574002425, R574002325, R574092325) are suitable for applications subject to environmental and regulatory compliance mandates. Non-compliant parts remain suitable for applications without such requirements.

Frequently Asked Questions (FAQ)

Q: Can R574002325 replace R574332400 in my application?

A: R574002325 is a SP3T configuration switch, while R574332400 is SP4T. Substitution is possible only if your application requires a maximum of three switching positions instead of four. All other electrical parameters (frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature) are identical.

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

A: SP4T (Single Pole Four Throw) provides four selectable output positions from a single input. SP3T (Single Pole Three Throw) provides three selectable output positions. The choice depends on the number of RF paths that must be switched in your application.

Q: Are all substitute parts available in the same package type?

A: Yes. All substitute parts listed are supplied in Module package type, identical to the R574332400.

Q: Which substitute parts have ROHS3 compliance?

A: R574002420, R574002425, R574002325, and R574092325 are designated as ROHS3 compliant. The remaining substitute parts do not specify RoHS compliance status.

Q: What is the inventory status of substitute parts?

A: All substitute parts are classified as active products with current inventory availability. R574002425 has the highest inventory level (1021 units) among SP4T options. R574092325 has the highest inventory level (976 units) among SP3T options.

Q: Do all substitute parts operate at the same frequency range?

A: Yes. All substitute parts operate across the identical frequency range of 0Hz to 3GHz with 50 Ohm impedance, 80dB minimum isolation, and 0.2dB maximum insertion loss.

Q: Can I use an SP3T part in a design originally specified for SP4T?

A: SP3T substitution is possible only if your circuit design and application requirements do not mandate four-position switching functionality. Circuit redesign may be necessary to accommodate the reduced switching capability.

Q: What supply voltage range do all substitute parts require?

A: All substitute parts require a supply voltage range of 10.2V to 13V, identical to the R574332400.

Q: Are there any differences in operating temperature range among substitute parts?

A: No. All substitute parts operate across the identical temperature range of -40°C to 85°C.
