ARD12012 RF Switch IC Equivalent & Substitute Parts

Part Overview

The ARD12012 is an RF Switch IC featuring a Single-Pole Double-Throw (SPDT) topology designed for general-purpose applications up to 18 GHz. This active product operates at 12V supply voltage with 50Ohm impedance and is housed in a Module with Pin Contacts package. The part is RoHS Compliant and classified as Moisture Sensitivity Level 1 (Unlimited). Equivalent and substitute parts are identified when they maintain critical RF performance parameters while potentially offering different supply voltage requirements or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ARD12012 are identified based on the following critical parameters that must remain constant:

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

The identified substitutes (ARD10012 and ARD15105) maintain all critical RF performance specifications and mechanical compatibility. The primary difference among these parts is the supply voltage requirement: ARD12012 and ARD10012 operate at 12V, while ARD15105 operates at 5V. Both substitute parts are manufactured by Panasonic Electric Works and belong to the ARD series.

Parameter Comparison

Engineering Selection Recommendations

All three parts (ARD12012, ARD10012, and ARD15105) maintain Active product status and meet RoHS compliance requirements. ARD12012 and ARD10012 are both RoHS Compliant and ROHS3 Compliant respectively, while ARD15105 is ROHS3 Compliant and REACH Unaffected.

Selection between ARD12012 and ARD10012 depends on supply voltage availability in the application circuit, as both operate at 12V with identical RF performance specifications. ARD15105 is suitable for applications requiring 5V supply voltage while maintaining the same RF performance envelope and mechanical compatibility.

All parts are housed in Module with Pin Contacts packages and support the full -55°C to 85°C operating temperature range, ensuring thermal compatibility across standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can ARD15105 be used as a direct replacement for ARD12012?

A: ARD15105 is electrically equivalent in RF performance but operates at 5V instead of 12V. Direct substitution requires that the application circuit supports 5V supply voltage. All RF parameters, impedance, frequency range, isolation, and insertion loss are identical.

Q: What is the primary difference between ARD12012 and ARD10012?

A: Both parts operate at 12V supply voltage and share identical RF specifications. The difference lies in RoHS compliance certification: ARD12012 is RoHS Compliant while ARD10012 is ROHS3 Compliant. Both are suitable for 12V applications.

Q: Are all substitute parts in the same package?

A: Yes. ARD12012, ARD10012, and ARD15105 are all housed in Module with Pin Contacts packages, ensuring mechanical and pin-level compatibility.

Q: What RF parameters must remain constant when selecting a substitute?

A: Critical parameters include SPDT circuit configuration, 0 Hz to 18 GHz frequency range, 60 dB minimum isolation, 0.5 dB maximum insertion loss, and 50 Ohm impedance. All substitute parts maintain these specifications.

Q: Are moisture sensitivity considerations the same across all parts?

A: Yes. All three parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
