AD91018Z Equivalent & Substitute Parts Reference

Part Overview

The AD91018Z is an IC processor manufactured by Analog Devices Inc. with an obsolete product status. This processor is no longer in active production, making identification of equivalent and substitute components essential for system maintenance, repair, and legacy design support. The part carries a Moisture Sensitivity Level (MSL) of 3 with a 168-hour rating, indicating specific handling requirements during storage and assembly.

Due to its obsolete status, direct replacement with active production alternatives is necessary for procurement and long-term supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AD91018Z is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Manufacturer: Analog Devices Inc. (maintained across all substitutes)
• Device Type: IC Processor
• Moisture Sensitivity Level: MSL 3 (168 Hours) compatibility
• Product Status: Active production alternatives required

Substitute Classification:

Direct Functional Equivalent: AD91171Z represents the manufacturer-recommended direct substitute, maintaining identical MSL rating and processor classification while offering active product status.

Extended Compatibility Alternative: ADSP-21061LKBZ-160 provides an alternative processor solution within the Analog Devices embedded processor portfolio, offering enhanced specifications including 32-bit DSP controller functionality, SHARC architecture, and active production status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select AD91171Z when maintaining functional and form-factor compatibility is required. This substitute maintains identical MSL specifications and processor classification while offering active production status, ROHS3 compliance, and REACH unaffected certification. Higher inventory availability (2301 units) supports immediate procurement.

For Enhanced Capability Applications: Select ADSP-21061LKBZ-160 when system design permits integration of advanced features including 32-bit floating-point DSP processing, SHARC architecture, synchronous serial port interface, and 40MHz clock rate. This option provides the highest inventory availability (2358 units) and full compliance certifications. Surface mount 225-PBGA packaging requires appropriate PCB design considerations.

Compliance Considerations: Both substitute parts maintain MSL 3 (168 Hours) rating, ensuring compatibility with existing moisture control procedures. ROHS3 compliance and REACH unaffected status of both substitutes support regulatory requirements for new designs and procurement.

Frequently Asked Questions (FAQ)

Q: Why is the AD91018Z marked as obsolete? A: The AD91018Z has reached end-of-life status in Analog Devices' product portfolio. While limited inventory remains available (787 units), the manufacturer no longer produces this component. Substitution is necessary for long-term supply chain planning.

Q: What is the difference between AD91171Z and ADSP-21061LKBZ-160? A: AD91171Z is the direct functional equivalent with identical processor classification. ADSP-21061LKBZ-160 is an enhanced alternative offering 32-bit DSP controller functionality, SHARC architecture, and higher clock rate (40MHz). Selection depends on whether existing system design can accommodate the enhanced feature set.

Q: Are the MSL ratings identical across all parts? A: Yes. The AD91018Z, AD91171Z, and ADSP-21061LKBZ-160 all carry MSL 3 (168 Hours) rating. Existing moisture control and handling procedures remain valid for all three components.

Q: What packaging differences exist between substitutes? A: AD91018Z and AD91171Z packaging specifications are not detailed in available data. ADSP-21061LKBZ-160 uses 225-PBGA (23x23) surface mount package. Verify mechanical compatibility with existing PCB designs before selection.

Q: Are both substitutes RoHS and REACH compliant? A: Yes. Both AD91171Z and ADSP-21061LKBZ-160 are ROHS3 compliant and REACH unaffected, supporting regulatory requirements for new designs and procurement in restricted substance environments.

Q: Which substitute offers better inventory availability? A: ADSP-21061LKBZ-160 provides the highest inventory (2358 units), followed by AD91171Z (2301 units). Both offer significantly higher availability than the obsolete AD91018Z (787 units).
