AD7862ARS-10 Equivalent & Substitute Parts

Part Overview

The AD7862ARS-10 is a 12-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 device features a dual SAR (Successive Approximation Register) architecture with a sampling rate of 250 kSPS and operates on 5V supply voltage for both analog and digital domains.

The AD7862ARS-10 is classified as obsolete. Active equivalent models are available with identical electrical and mechanical specifications, making direct substitution feasible for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution of the AD7862ARS-10 is based on strict equivalence across all electrical and mechanical parameters. The substitute parts maintain identical specifications for resolution, sampling rate, input configuration, architecture, supply voltages, operating temperature range, and package form factor.

The following parameters determine substitutability:

  • 12-bit resolution
  • 250 kSPS sampling rate
  • 4 single-ended inputs
  • Dual SAR converter configuration
  • 5V analog and digital supply
  • -40°C to 85°C operating range
  • 28-SSOP surface mount package

All substitute parts listed below meet these criteria without exception.

Engineering Selection Recommendations

The AD7862ARSZ-10, AD7862ARSZ-2, and AD7862ARSZ-3 are direct functional equivalents to the obsolete AD7862ARS-10. All three substitute parts are classified as active products and maintain complete electrical and mechanical compatibility.

For new designs and production applications, any of the three substitute parts may be selected based on availability and packaging requirements. All substitute parts are supplied in tube packaging and comply with ROHS3 standards. The substitute parts feature higher moisture sensitivity levels (MSL 3, 168 hours) compared to the original part (MSL 1, unlimited), which may require adjusted handling procedures during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can AD7862ARSZ-10, AD7862ARSZ-2, and AD7862ARSZ-3 be used interchangeably with AD7862ARS-10?

A: Yes. All three substitute parts maintain identical electrical specifications, pin configuration, and 28-SSOP package dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between the substitute part numbers?

A: The suffix designations (-10, -2, -3) indicate different manufacturing date codes or tape reel configurations. Electrical and mechanical specifications are identical across all variants.

Q: Are there packaging differences between the main part and substitutes?

A: The AD7862ARS-10 packaging type is not specified in available documentation. The substitute parts are supplied in tube packaging. Verify packaging compatibility with your assembly process requirements.

Q: What is the impact of the higher moisture sensitivity level on the substitute parts?

A: The substitute parts have MSL 3 (168 hours) compared to MSL 1 (unlimited) for the original part. This requires adherence to moisture control procedures during storage and handling. Parts must be stored in dry conditions and used within the specified time window after opening the moisture barrier bag.

Q: Are the substitute parts RoHS compliant?

A: Yes. All substitute parts (AD7862ARSZ-10, AD7862ARSZ-2, AD7862ARSZ-3) are ROHS3 compliant. The original AD7862ARS-10 RoHS status is not specified.

Q: What is the current availability of substitute parts?

A: AD7862ARSZ-10: 1585 pcs in stock; AD7862ARSZ-2: 1410 pcs in stock; AD7862ARSZ-3: 1356 pcs in stock.
