AD7862ARSZ-2 Equivalent & Substitute Parts

Part Overview

The AD7862ARSZ-2 is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring simultaneous sampling across multiple input channels. This SAR (Successive Approximation Register) architecture device features 4 single-ended inputs with 2 integrated ADC converters, operating at a 250 kSPS sampling rate. The part is currently active in production and widely stocked, with 1410 units available in new original condition. Equivalent substitute parts are identified based on identical electrical specifications, mechanical packaging, and compliance certifications, enabling direct replacement in existing designs without circuit modification.

Substitute Part Grouping Explanation

Substitute parts for the AD7862ARSZ-2 are identified as parametric equivalents within the AD7862 base product family. Substitution is valid when all of the following criteria are met:

• Resolution: 12 bits
• Sampling rate: 250 kSPS
• Input configuration: 4 single-ended inputs
• ADC converter count: 2
• Architecture: SAR with simultaneous sampling capability
• Data interface: Parallel
• Supply voltages: 5V analog and 5V digital
• Package: 28-SSOP surface mount
• Operating temperature range: -40°C to 85°C
• Compliance: ROHS3 compliant, REACH unaffected

The AD7862ARSZ-3 and AD7862ARSZ-10 meet all these criteria and are direct functional equivalents. Differences between these part numbers reflect manufacturing date codes or internal revision levels that do not affect electrical performance or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AD7862ARSZ-2, AD7862ARSZ-3, and AD7862ARSZ-10—are active production components with identical electrical and mechanical specifications. Selection between these equivalents should be based on:

• Availability: AD7862ARSZ-10 has the highest current inventory (1585 units), followed by AD7862ARSZ-2 (1410 units) and AD7862ARSZ-3 (1356 units).
• Compliance: All parts maintain ROHS3 compliance and REACH unaffected status, suitable for regulated applications.
• Packaging and handling: All parts are supplied in tube packaging with identical MSL rating (3, 168 hours), requiring equivalent storage and handling protocols.

No electrical performance differentiation exists between these parts. Direct substitution is permissible in any application where the AD7862ARSZ-2 is specified.

Frequently Asked Questions (FAQ)

Q: Can AD7862ARSZ-3 or AD7862ARSZ-10 be used as direct replacements for AD7862ARSZ-2 without PCB modification?

A: Yes. All three parts share identical pin configurations, electrical specifications, and package dimensions (28-SSOP). No circuit changes are required for substitution.

Q: What is the difference between AD7862ARSZ-2, AD7862ARSZ-3, and AD7862ARSZ-10?

A: These part numbers represent the same base product (AD7862) with different manufacturing date codes or internal revision levels. No functional or electrical differences exist between them.

Q: Are these parts suitable for high-temperature applications?

A: All three parts operate across the -40°C to 85°C temperature range. Applications requiring operation beyond 85°C require alternative device selection.

Q: What is the moisture sensitivity level, and how does it affect storage?

A: All parts carry MSL rating 3 (168 hours), indicating they must be stored in controlled humidity environments and used within 168 hours of exposure to ambient conditions exceeding 30% relative humidity.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for EU and similar markets.

Q: Can these parts be used in applications requiring simultaneous sampling across all four inputs?

A: Yes. The simultaneous sampling feature is present in all three equivalent parts, enabling synchronized data acquisition across the 4 single-ended input channels.
