Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8361ARM is determined by strict equivalence across the following electrical and mechanical parameters:

• Frequency specification: 2.5GHz
• RF application type: Cellular, CDMA, W-CDMA
• Input signal range: 0–700mV
• Detection accuracy: ±0.25dB
• Supply voltage range: 2.7V–5.5V
• Supply current: 1.1mA
• Package type: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Pin configuration: 8-pin

The AD8361ARMZ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Engineering Selection Recommendations

The AD8361ARMZ is the direct functional equivalent of the AD8361ARM. Selection between these parts is determined by application requirements and regulatory compliance:

• For new designs and systems requiring active component support, the AD8361ARMZ is the appropriate selection due to active product status and ROHS3 compliance certification.
• For legacy system maintenance where the AD8361ARM is currently deployed, the AD8361ARMZ provides identical electrical and mechanical compatibility with the added benefit of REACH compliance documentation.
• Both parts share identical pin configuration, electrical performance, and package dimensions, enabling direct substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can AD8361ARMZ replace AD8361ARM in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is possible without design changes.

Q: What is the difference between AD8361ARM and AD8361ARMZ? A: The primary differences are product status (obsolete vs. active) and regulatory compliance documentation. AD8361ARMZ includes ROHS3 and REACH compliance certifications. Electrical specifications and package configuration are identical.

Q: Are there pin-to-pin compatibility concerns? A: No. Both parts use the 8-pin TSSOP/MSOP package with identical pinout and electrical characteristics.

Q: Which part should be selected for new production? A: AD8361ARMZ should be selected for new designs due to active product status and current regulatory compliance certifications.

Q: Is packaging format a consideration for substitution? A: AD8361ARM is supplied in standard packaging, while AD8361ARMZ is supplied in tube packaging. Both contain identical die and electrical performance. Packaging format does not affect electrical compatibility.
