MAX5171AEEE Equivalent & Substitute Parts

Part Overview

The MAX5171AEEE is a 14-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring single-channel voltage output conversion. This component features SPI interface compatibility, external reference capability, and R-2R architecture for precision analog signal generation.

The MAX5171AEEE is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical specifications and package compatibility to ensure seamless integration into existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX5171AEEE is determined by strict equivalence across the following critical parameters:

• 14-bit resolution with single D/A converter configuration
• Voltage-buffered output type with SPI digital interface
• External reference architecture using R-2R topology
• Dual 5V supply requirements (analog and digital)
• Settling time of 12µs typical
• INL/DNL specification of ±1 LSB maximum
• Operating temperature range of -40°C to 85°C
• 16-SSOP surface mount package with 0.154" width

Parts meeting all these criteria are classified as direct functional equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The MAX5171AEEE+ serves as the direct functional equivalent to the obsolete MAX5171AEEE. Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring pin-for-pin compatibility and circuit-level interchangeability.

The primary distinction between these parts is product status and regulatory compliance. The MAX5171AEEE+ is classified as active, ensuring continued availability and manufacturer support. Additionally, the MAX5171AEEE+ achieves ROHS3 compliance, whereas the original MAX5171AEEE is RoHS non-compliant. This compliance improvement aligns with current environmental and regulatory requirements for electronic component procurement.

For new designs and production transitions from obsolete inventory, the MAX5171AEEE+ is the appropriate selection. Both parts share identical moisture sensitivity classification (MSL 1) and REACH status, confirming equivalent handling and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX5171AEEE+ be used as a direct replacement for MAX5171AEEE?

A: Yes. The MAX5171AEEE+ is electrically and mechanically identical to the MAX5171AEEE across all specified parameters, including resolution, output type, interface protocol, supply voltages, settling time, and package configuration. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The MAX5171AEEE is classified as obsolete, indicating discontinued manufacturing and limited availability. The MAX5171AEEE+ is active, ensuring ongoing production, manufacturer technical support, and long-term supply chain reliability.

Q: Does the RoHS3 compliance of MAX5171AEEE+ affect compatibility?

A: No. RoHS3 compliance represents an improvement in environmental and regulatory adherence. The MAX5171AEEE+ maintains all electrical and mechanical specifications identical to the original part. RoHS compliance does not alter functional performance or circuit behavior.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 16-SSOP surface mount package with identical dimensions (0.154" width, 3.90mm). Pinout and mechanical footprint are identical, confirming direct PCB compatibility.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in 14-bit resolution, single-channel D/A converter configuration, voltage-buffered SPI output, external reference R-2R architecture, dual 5V supply requirements, 12µs settling time, ±1 LSB INL/DNL specification, -40°C to 85°C operating range, and 16-SSOP surface mount package. The MAX5171AEEE+ meets all these criteria.

Q: Are moisture sensitivity and handling requirements identical?

A: Yes. Both parts share MSL 1 (Unlimited) classification, indicating identical moisture sensitivity and storage requirements. No differences in handling procedures or environmental controls are necessary.
