AD7865ASZ-2REEL Equivalent & Substitute Parts

Part Overview

The AD7865ASZ-2REEL is a 14-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring simultaneous sampling across four single-ended inputs. This SAR (Successive Approximation Register) architecture device operates at a 350 kSPS sampling rate with both external and internal reference options, making it suitable for industrial measurement and control systems. The part is currently active in production and ROHS3 compliant, with 743 units available in new original stock.

Equivalent substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and functional performance characteristics. This ensures seamless integration into existing designs without circuit modification or re-qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD7865ASZ-2REEL is determined by strict equivalence across the following critical parameters:

• Resolution: 14-bit ADC
• Sampling Performance: 350 kSPS conversion rate
• Channel Configuration: 4 single-ended inputs with simultaneous sampling capability
• Interface Protocol: Parallel data output
• Power Supply Requirements: 5V analog and digital supplies
• Physical Form Factor: 44-QFP package (10x10 mm)
• Temperature Operating Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 Compliant

The AD7865ASZ-3REEL meets all these criteria and is classified as a parametric equivalent. The difference between the -2REEL and -3REEL designations relates to packaging reel specifications, not functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the AD7865ASZ-2REEL and AD7865ASZ-3REEL are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability: AD7865ASZ-3REEL has higher inventory (1620 units) compared to AD7865ASZ-2REEL (743 units)
• Reel Configuration: The numeric suffix (-2 or -3) indicates different reel specifications for automated assembly; verify your pick-and-place equipment compatibility with the specific reel format
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for applications requiring environmental regulatory adherence
• Supply Chain Continuity: Either part provides equivalent long-term availability as both maintain active product status

Frequently Asked Questions (FAQ)

Q: Can AD7865ASZ-3REEL be used as a direct replacement for AD7865ASZ-2REEL?

A: Yes. Both parts are electrically and mechanically identical. The -2 and -3 designations refer only to reel packaging specifications used during manufacturing and assembly. Functional performance, pin configuration, and electrical characteristics are identical.

Q: What does the reel designation (-2REEL vs -3REEL) mean?

A: The numeric suffix indicates the reel format and quantity per reel used for automated component placement. This affects only the packaging logistics and pick-and-place machine compatibility, not the component itself.

Q: Are there any temperature or voltage differences between these parts?

A: No. Both parts operate identically across the -40°C to 85°C temperature range and require 5V analog and digital supplies. All electrical specifications are equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AD7865ASZ-2REEL and AD7865ASZ-3REEL are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What should I verify before substituting these parts?

A: Confirm that your assembly equipment supports the reel format of the substitute part. Verify that your procurement system can accommodate the part number change. All other design and assembly parameters remain unchanged.
