ARD12024 RF Switch IC Equivalent & Substitute Parts

Part Overview

The ARD12024 is a General Purpose SPDT RF Switch IC operating at frequencies up to 18 GHz with 50 Ohm impedance. This active product from Panasonic Electric Works is designed for reflective topology applications requiring 60 dB minimum isolation and 0.5 dB maximum insertion loss. The part operates on 24V supply voltage across the temperature range of -55°C to 85°C in a Module with Pin Contacts package format.

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 electrical specifications.

Substitute Part Grouping Explanation

Substitution for the ARD12024 is determined by strict equivalence across the following critical parameters:

RF Type: General Purpose
Topology: Reflective
Circuit Configuration: SPDT
Frequency Range: 0 Hz ~ 18 GHz
Isolation: 60 dB (Min)
Insertion Loss: 0.5 dB (Max)
Test Frequency: 18 GHz
Impedance: 50 Ohm
Operating Temperature: -55°C ~ 85°C
Package / Case: Module, Pin Contacts

The substitute parts ARD10024, ARD10012, and ARD15105 maintain identical RF performance and electrical characteristics. The primary differentiation among these parts is the supply voltage requirement: ARD10024 operates at 24V (matching the main part), ARD10012 operates at 12V, and ARD15105 operates at 5V. All three parts are manufactured by Panasonic Electric Works and share the same functional topology and frequency specifications.

Engineering Selection Recommendations

All four parts—ARD12024, ARD10024, ARD10012, and ARD15105—are active products from Panasonic Electric Works with identical RF performance specifications. Selection among these parts is determined by system voltage requirements:

ARD12024 and ARD10024 are direct equivalents for 24V supply systems
ARD10012 is suitable for 12V supply systems
ARD15105 is suitable for 5V supply systems

All parts maintain RoHS compliance (ARD12024 is RoHS Compliant; ARD10024, ARD10012, and ARD15105 are ROHS3 Compliant) and share MSL Level 1 (Unlimited) moisture sensitivity rating. The ECCN classification EAR99 and HTSUS code 8536.49.0055 are consistent across all parts.

Frequently Asked Questions (FAQ)

Q: Can ARD10024 be used as a direct replacement for ARD12024?

A: Yes. Both parts operate at 24V supply voltage and are electrically and functionally equivalent across all RF parameters including frequency range, isolation, insertion loss, impedance, and operating temperature.

Q: What is the primary difference between ARD12024 and its substitutes?

A: The primary difference is supply voltage. ARD12024 and ARD10024 require 24V, ARD10012 requires 12V, and ARD15105 requires 5V. All other electrical and RF specifications are identical.

Q: Are these parts pin-compatible?

A: All parts use Module with Pin Contacts packaging. Pin compatibility must be verified against the specific application schematic and PCB layout, as package designation alone does not guarantee identical pinout.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS directives. ROHS3 refers to the third iteration of the RoHS directive. Both are acceptable for applications requiring RoHS compliance.

Q: Can I substitute a 5V part (ARD15105) in a 24V system?

A: No. Supply voltage is a critical operating parameter. Using ARD15105 in a 24V system will result in device failure or damage. The substitute part must match the system voltage requirement.

Q: Are all these parts currently in stock?

A: Inventory status varies. ARD12024 has 761 units, ARD10024 has 2200 units, ARD10012 has 699 units, and ARD15105 has 774 units available as new original stock.
