Substitute Part Grouping Explanation

Substitute parts for the AD7680ARM-REEL7 are classified based on electrical and mechanical compatibility within the allowed parameter ranges:

Direct Manufacturer Equivalent (AD7680ARMZ): Identical electrical specifications and package footprint. Differs only in packaging format (Tube vs. Reel) and product status (Active vs. Obsolete). Pin-for-pin compatible with no design modifications required.

Parametric Equivalent (AD7680BRMZ-REEL7): Matches all electrical parameters and package specifications. Differs in product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel® vs. Reel). Functionally interchangeable with identical pinout and performance characteristics.

Similar Substitute (AD7988-1BRMZ): Shares core SAR architecture, 16-bit resolution, and 100 kSPS sampling rate. Differs in input type (Pseudo-Differential vs. Single Ended), reference type (External vs. Supply), package size (10-MSOP vs. 8-MSOP), and operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). Requires PCB layout modifications and reference circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: AD7680ARMZ and AD7680BRMZ-REEL7 are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and supply chain stability. Both are ROHS3 Compliant and REACH Unaffected, meeting modern regulatory requirements. Selection between these two depends on packaging requirements: AD7680ARMZ is supplied in Tube format, while AD7680BRMZ-REEL7 is supplied in Cut Tape & Digi-Reel® format. No circuit modifications are required for either option.

For Design Flexibility: AD7988-1BRMZ is suitable only when design constraints permit PCB layout modifications and reference circuit redesign. The shift from Single Ended to Pseudo-Differential input architecture, combined with External reference requirements and tighter supply voltage tolerances (2.375V ~ 2.625V), necessitates comprehensive circuit validation. The extended operating temperature range (-40°C ~ 125°C) may provide advantages in high-temperature applications. The 10-MSOP package requires footprint changes on the PCB.

Frequently Asked Questions (FAQ)

Q: Can AD7680ARMZ be used as a direct drop-in replacement for AD7680ARM-REEL7?

A: Yes. AD7680ARMZ is electrically and functionally identical to AD7680ARM-REEL7. The only difference is packaging format (Tube vs. Reel) and product status (Active vs. Obsolete). No design changes are required. Pin configuration, electrical performance, and operating parameters are identical.

Q: What is the key difference between AD7680BRMZ-REEL7 and AD7680ARMZ?

A: Both parts are parametrically equivalent with identical electrical specifications and 8-MSOP package footprint. The primary difference is packaging format: AD7680BRMZ-REEL7 is supplied in Cut Tape & Digi-Reel® format, while AD7680ARMZ is supplied in Tube format. Selection depends on procurement and assembly line requirements.

Q: Why is AD7988-1BRMZ classified as a similar substitute rather than a direct equivalent?

A: AD7988-1BRMZ differs in multiple critical parameters: input type (Pseudo-Differential vs. Single Ended), reference type (External vs. Supply), package size (10-MSOP vs. 8-MSOP), and supply voltage range (2.375V ~ 2.625V vs. 2.5V ~ 5.5V). These differences require PCB redesign, reference circuit modifications, and comprehensive system validation. It is not a pin-for-pin replacement.

Q: Can I use AD7988-1BRMZ in an existing design without modifications?

A: No. The 10-MSOP package requires PCB footprint changes. The Pseudo-Differential input architecture and External reference requirement necessitate circuit redesign. The tighter supply voltage tolerance (2.375V ~ 2.625V) may require power supply modifications. Comprehensive design review and testing are mandatory before implementation.

Q: Are all substitute parts ROHS3 Compliant and REACH Unaffected?

A: Yes. AD7680ARMZ, AD7680BRMZ-REEL7, and AD7988-1BRMZ are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All listed parts have MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Which substitute should I choose for new designs?

A: For new designs, AD7680ARMZ or AD7680BRMZ-REEL7 are recommended as they maintain identical electrical specifications and package footprint to the original AD7680ARM-REEL7. Both are Active products with full regulatory compliance. AD7988-1BRMZ should be considered only if the extended operating temperature range (-40°C ~ 125°C) or Pseudo-Differential input capability provides specific design advantages that justify circuit modifications.
