MAX503CNG Equivalent & Substitute Parts

Part Overview

The MAX503CNG is a 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications. This component features a single voltage-buffered output with parallel data interface, supporting both external and internal reference configurations. The device operates with dual supply voltages (±5V analog, 5V digital) and is housed in a 24-pin DIP package for through-hole mounting.

The MAX503CNG is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX503CNG is determined by strict equivalence across the following critical parameters:

• Resolution and Architecture: 10-bit resolution with R-2R architecture
• Output Configuration: Single voltage-buffered output
• Data Interface: Parallel interface
• Supply Voltage Requirements: ±5V analog supply and 5V digital supply
• Performance Specifications: Settling time of 25µs (typical), INL/DNL of ±0.5 LSB (max) and ±1 LSB (max)
• Package Compatibility: 24-pin DIP package (0.300", 7.62mm) with through-hole mounting
• Reference Configuration: Support for both external and internal reference types

The MAX503CNG+ is identified as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX503CNG+ is the direct functional equivalent of the MAX503CNG. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX503CNG is classified as obsolete, while the MAX503CNG+ maintains active product status. Additionally, the MAX503CNG+ achieves ROHS3 compliance, whereas the original MAX503CNG is RoHS non-compliant. Both devices maintain REACH Unaffected status and are classified under ECCN EAR99.

For new designs or system redesigns, the MAX503CNG+ is the appropriate selection due to its active status and enhanced regulatory compliance. For legacy system maintenance requiring exact part replacement, the MAX503CNG+ provides complete functional and mechanical compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the MAX503CNG+ be used as a direct replacement for the MAX503CNG?

A: Yes. The MAX503CNG+ is electrically and mechanically identical to the MAX503CNG.
