Substitute Part Grouping Explanation

Substitution for the AD91018Z-RL is determined by the following criteria:

Primary Substitution Criteria:

• Manufacturer alignment (Analog Devices Inc.)
• Functional classification (IC Processor)
• Moisture Sensitivity Level compatibility (MSL 3)
• Product status transition from obsolete to active availability

The substitute parts identified maintain electrical and mechanical compatibility within the processor category while offering active product status and improved inventory availability. Substitution is based strictly on the parameters provided and the functional equivalence of the components within the IC processor classification.

Parameter Comparison

Engineering Selection Recommendations

AD91171Z is the primary manufacturer-recommended substitute for AD91018Z-RL. Both components are IC processors from Analog Devices Inc. with identical Moisture Sensitivity Level ratings. AD91171Z offers active product status with significantly higher inventory availability (2301 pieces) and full ROHS3 compliance and REACH unaffected status, providing superior long-term supply chain reliability.

ADSP-21061LKBZ-160 represents an alternative substitute within the Analog Devices processor family. This component is classified as a 32-bit DSP controller with enhanced specifications including 40MHz clock rate, 128kB on-chip RAM, and 225-PBGA packaging. It maintains MSL 3 compatibility and offers active product status with robust inventory levels (2358 pieces). This option is suitable for applications requiring higher processing capability and embedded system integration.

Both substitutes comply with current environmental and regulatory standards (ROHS3 and REACH), ensuring compliance with modern manufacturing and distribution requirements.

Frequently Asked Questions (FAQ)

Q: Why is AD91018Z-RL classified as obsolete? A: AD91018Z-RL has reached end-of-life status with Analog Devices Inc. and is no longer manufactured. Substitute parts provide continued access to equivalent processor functionality through active product lines.

Q: Are AD91171Z and ADSP-21061LKBZ-160 directly interchangeable with AD91018Z-RL? A: Both parts are manufacturer-recommended substitutes within the Analog Devices processor portfolio. Substitution suitability depends on specific application requirements and circuit design parameters not provided in this reference. Electrical and mechanical compatibility must be verified against your system specifications.

Q: What does Moisture Sensitivity Level 3 (168 Hours) mean? A: MSL 3 indicates the component requires controlled moisture exposure conditions. The 168-hour rating specifies the maximum time the component can be exposed to moisture at specified temperature and humidity levels before soldering. All listed parts maintain this identical MSL rating.

Q: What is the difference between AD91171Z and ADSP-21061LKBZ-160? A: AD91171Z is a direct processor substitute with matching functional classification. ADSP-21061LKBZ-160 is a 32-bit DSP controller with additional embedded capabilities, higher clock rate (40MHz), and larger on-chip RAM (128kB). Selection depends on whether your application requires the enhanced DSP functionality or equivalent processor replacement.

Q: Are both substitutes ROHS3 compliant? A: Yes. Both AD91171Z and ADSP-21061LKBZ-160 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What packaging is used for these components? A: Specific packaging details are not provided in the available parameters for AD91018Z-RL and AD91171Z. ADSP-21061LKBZ-160 uses 225-PBGA (23x23) packaging. Packaging compatibility must be verified against your PCB design requirements.
