Both parts maintain identical electrical performance, mechanical compatibility, and environmental operating specifications. Inventory availability may also influence selection, with ARD15105Q currently showing 755 units in stock compared to 702 units for ARD15105C.

Frequently Asked Questions (FAQ)

Q: Can ARD15105Q be used as a direct replacement for ARD15105C?

A: Yes. Both parts are parametric equivalents with identical RF performance specifications, impedance characteristics, frequency range, isolation, insertion loss, supply voltage, operating temperature range, and package form factor. The primary difference is the RoHS certification level (ROHS3 vs. RoHS Compliant).

Q: What determines whether a part qualifies as a substitute for the ARD15105C?

A: Substitution eligibility requires matching across all critical parameters: SPDT circuit topology, 0Hz to 18GHz frequency range, 60dB minimum isolation, 0.5dB maximum insertion loss, 50Ohm impedance, 5V supply voltage, -55°C to 85°C operating temperature, Module package with pin contacts, and MSL 1 rating.

Q: Are there any package or pinout differences between ARD15105C and ARD15105Q?

A: No. Both parts use identical Module packaging with pin contacts, ensuring mechanical and electrical compatibility in PCB layouts and circuit designs.

Q: What is the significance of the ROHS3 certification on ARD15105Q?

A: ROHS3 Compliance represents an updated RoHS certification standard. ARD15105Q also carries REACH Unaffected status, indicating compliance with additional regulatory frameworks. Both certifications are equivalent or superior to standard RoHS Compliance for most applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical and mechanical specifications are identical, allowing direct substitution without design modifications or re-qualification testing based on the provided parameters.
