ARD15112 RF Switch IC SPDT 18GHz Equivalent & Substitute Parts

Part Overview

The ARD15112 is an RF Switch IC featuring Single-Pole Double-Throw (SPDT) topology designed for general-purpose applications up to 18 GHz. Manufactured by Panasonic Electric Works, this component operates at 12V supply voltage with 50 Ohm impedance and is housed in a Module with Pin Contacts package. The part maintains Active product status with RoHS compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts become necessary when addressing supply chain constraints, inventory availability, or specific application requirements while maintaining electrical and mechanical compatibility within the RF switching circuit design.

Substitute Part Grouping Explanation

Substitution eligibility for the ARD15112 is determined by strict equivalence across the following critical parameters:

Circuit topology: SPDT configuration
Frequency capability: 0 Hz ~ 18 GHz minimum
Isolation performance: 60 dB minimum
Insertion loss: 0.5 dB maximum
Impedance: 50 Ohm
Operating temperature range: -55°C ~ 85°C
Package form factor: Module with Pin Contacts
Moisture sensitivity: MSL 1 (Unlimited)

The ARD10012 and ARD15105 meet all electrical and mechanical parameters required for direct substitution. Differences in supply voltage and RoHS certification variants do not preclude substitution when circuit design accommodates the specified supply voltage.

Engineering Selection Recommendations

All three parts maintain Active product status with full RoHS compliance, ensuring regulatory alignment for current and future applications. The ARD15112 and ARD10012 operate identically at 12V supply voltage and are direct functional equivalents. The ARD15105 provides equivalent RF performance at 5V supply voltage, requiring circuit design accommodation for the reduced supply voltage but offering no electrical performance degradation in RF switching characteristics.

Selection between ARD10012 and ARD15112 depends on inventory availability and supply chain considerations, as both parts are electrically and mechanically identical. The ARD15105 is selected when 5V supply voltage is required or preferred in the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can ARD15105 replace ARD15112 in existing designs?

A: ARD15105 provides equivalent RF switching performance but operates at 5V instead of 12V. Substitution requires circuit design modification to accommodate the different supply voltage. All RF parameters remain identical.

Q: What determines if a part is a valid substitute?

A: Valid substitutes must maintain identical SPDT circuit topology, 0-18 GHz frequency range, 60 dB minimum isolation, 0.5 dB maximum insertion loss, 50 Ohm impedance, -55°C to 85°C operating range, and Module Pin Contacts package form factor.

Q: Are there differences in reliability between these parts?

A: All three parts share identical moisture sensitivity rating (MSL 1, Unlimited), operating temperature range, and Active product status. RoHS certification variants (RoHS vs ROHS3) reflect regulatory timeline differences but do not indicate reliability variation.

Q: Can supply voltage differences affect RF performance?

A: Supply voltage differences do not affect RF switching characteristics including isolation, insertion loss, or frequency response. Circuit design must accommodate the specified supply voltage for proper device operation.

Q: What is the significance of the different base product numbers?

A: Base product numbers (ARD151 for ARD15112 and ARD15105; ARD100 for ARD10012) indicate product line designation but do not affect substitution eligibility when all electrical and mechanical parameters match.
