ARD15124 RF Switch IC SPDT 18GHz Equivalent & Substitute Parts

Part Overview

The ARD15124 is a general-purpose RF switch IC with SPDT (Single Pole Double Throw) topology designed for operation up to 18 GHz. This Panasonic Electric Works component operates at 24V supply voltage and provides 60 dB minimum isolation with 0.5 dB maximum insertion loss at 50 Ohm impedance. The part is active in production status and RoHS compliant, making it suitable for modern RF switching applications requiring high-frequency performance and environmental compliance.

Equivalent and substitute parts become necessary when addressing supply chain constraints, inventory availability, or specific system voltage requirements while maintaining identical RF performance characteristics and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ARD15124 is determined by strict equivalence across the following critical parameters:

RF Performance: Frequency range (0 Hz ~ 18 GHz), circuit topology (SPDT), isolation (60 dB minimum), and insertion loss (0.5 dB maximum) must be identical
Electrical Compatibility: Impedance (50 Ohm) and operating temperature range (-55°C ~ 85°C) must match
Mechanical Compatibility: Package type (Module, Pin Contacts) must be identical
Supply Voltage: Substitute parts may operate at different supply voltages (5V, 12V, or 24V) provided all other parameters remain equivalent
Compliance: Parts must maintain active product status and appropriate RoHS certification

Three substitute parts meet these criteria: ARD10012 (12V supply), ARD10024 (24V supply), and ARD15105 (5V supply). All three maintain identical RF performance, impedance, temperature range, and mechanical packaging while differing only in supply voltage requirements.

Engineering Selection Recommendations

All three substitute parts maintain active product status and appropriate RoHS certification. Selection between ARD15124, ARD10012, ARD10024, and ARD15105 depends solely on system supply voltage requirements:

ARD15124 and ARD10024: Both operate at 24V supply voltage. ARD10024 offers higher inventory availability (2200 pcs) compared to ARD15124 (800 pcs) while maintaining identical electrical and mechanical specifications. ARD10024 carries ROHS3 certification versus RoHS compliance for ARD15124.
ARD10012: Operates at 12V supply voltage. Suitable for systems designed around 12V power distribution. Inventory availability is 699 pcs.
ARD15105: Operates at 5V supply voltage. Suitable for low-voltage system architectures. Inventory availability is 774 pcs. Carries REACH Unaffected designation in addition to ROHS3 compliance.

All parts share identical RF performance metrics, mechanical packaging, and temperature operating range, ensuring functional interchangeability within their respective voltage domains.

Frequently Asked Questions (FAQ)

Q: Can ARD15105 (5V) be used as a direct replacement for ARD15124 (24V)?

A: No. While RF performance, impedance, frequency range, isolation, insertion loss, and mechanical packaging are identical, the supply voltage differs. ARD15105 requires 5V operation, whereas ARD15124 requires 24V. System power supply architecture must support the substitute part's voltage requirement.

Q: Are all substitute parts mechanically compatible with ARD15124?

A: Yes. All substitute parts use identical Module, Pin Contacts packaging. Mechanical mounting and pin configuration are equivalent across ARD15124, ARD10012, ARD10024, and ARD15105.

Q: What is the primary difference between ARD10024 and ARD15124?

A: Both operate at 24V supply voltage and share identical RF specifications. The primary differences are RoHS certification level (ROHS3 for ARD10024 versus RoHS Compliant for ARD15124) and inventory availability (2200 pcs for ARD10024 versus 800 pcs for ARD15124).

Q: Can I use ARD10012 in a 24V system?

A: No. ARD10012 is specified for 12V operation. Using it in a 24V system will result in component damage or malfunction. Supply voltage must match the part specification.

Q: Do all substitute parts maintain the same frequency performance?

A: Yes. All substitute parts operate across the identical frequency range of 0 Hz ~ 18 GHz with 60 dB minimum isolation and 0.5 dB maximum insertion loss at 50 Ohm impedance.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including ARD15124 and its substitutes, have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
