DS1851E-010 Equivalent & Substitute Parts
Part Overview
The DS1851E-010 is an 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring dual voltage output channels. This component features I2C interface control, unbuffered voltage output, and operates across a 3V to 5.5V supply range suitable for mixed-signal embedded systems.
The DS1851E-010 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support long-term product maintenance where original components are no longer in production.

Substitute Part Grouping Explanation
Substitute parts for the DS1851E-010 are identified based on strict electrical and mechanical parameter matching within the DS1851 product family. The substitution criteria are:
- Resolution & Channel Count: 8-bit resolution with dual D/A converters
- Interface Protocol: I2C digital control interface
- Output Configuration: Voltage-mode unbuffered output
- Supply Voltage Compatibility: 3V to 5.5V operating range
- Thermal Range: -40°C to 95°C operating temperature
- Package Form Factor: 8-TSSOP surface mount package
- Linearity Specifications: INL/DNL performance within ±2/±1 LSB
Only parts meeting all these criteria are considered direct substitutes. Packaging variants (tube vs. alternative formats) do not affect functional substitutability when electrical specifications remain identical.

Engineering Selection Recommendations
The DS1851E-010+ serves as the direct functional substitute for the obsolete DS1851E-010. Both components share identical electrical specifications, interface protocols, and package form factors, ensuring pin-compatible replacement in existing circuit designs.
The DS1851E-010+ offers the advantage of active product status, meaning continued manufacturer support and supply availability. Additionally, the DS1851E-010+ meets ROHS3 compliance requirements, whereas the original DS1851E-010 does not. This distinction is significant for applications subject to environmental or regulatory compliance mandates.
Selection between these parts should be based on supply chain requirements and regulatory compliance needs. For new designs or redesigns, the DS1851E-010+ is the appropriate choice. For legacy system maintenance where RoHS compliance is not a constraint, either part functions identically within the specified electrical and thermal parameters.
Frequently Asked Questions (FAQ)
Q: Can the DS1851E-010+ directly replace the DS1851E-010 in existing designs?
A: Yes. Both parts are electrically and mechanically identical. The DS1851E-010+ is a pin-compatible, form-factor-compatible replacement with no circuit modifications required.
Q: What is the primary difference between these two parts?
A: The DS1851E-010 is obsolete with non-compliant RoHS status. The DS1851E-010+ is an active product meeting ROHS3 compliance standards. Electrical performance and package specifications are identical.
Q: Are there any supply voltage or temperature range differences?
A: No. Both parts operate across 3V to 5.5V supply voltage and -40°C to 95°C temperature range with identical linearity specifications (±2/±1 LSB INL/DNL).
Q: Does the packaging format affect substitutability?
A: No. Both parts use the 8-TSSOP surface mount package. Packaging variants (tube vs. other formats) do not affect electrical or mechanical compatibility.
Q: Which part should be selected for new designs?
A: The DS1851E-010+ should be selected for new designs due to active product status, continued manufacturer support, and ROHS3 compliance alignment with modern regulatory requirements.
Q: Is the I2C interface identical between both parts?
A: Yes. Both parts implement identical I2C digital control interfaces with supply-referenced voltage output architecture.
