MAX173CWG+ Equivalent & Substitute Parts Reference

Part Overview

The MAX173CWG+ is a 10-bit analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device features an internal reference and operates at a 200 kHz sampling rate with parallel data interface output. The part is currently in active production status and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to supply constraints, inventory requirements, or design flexibility needs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX173CWG+ must maintain strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are based on the following key parameters:

• 10-bit resolution requirement
• 200 kHz sampling rate specification
• Single-ended input configuration with 1 input channel
• SAR architecture with internal reference
• Parallel data interface output
• Dual supply voltage capability (5V, -12V, -15V for both analog and digital supplies)
• 24-SOIC surface mount package with 7.50mm width
• Operating temperature range of 0°C to 70°C
• Active product status and ROHS3 compliance

Parts meeting all these parameters are considered parametric equivalents and direct substitutes. No deviations from these specifications are permitted for true equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MAX173CWG+ is the identified parametric equivalent and direct substitute for itself based on the provided specifications. Selection of this part is supported by its active product status, ensuring continued availability and manufacturing support. The device maintains full ROHS3 compliance and carries an MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling. These compliance certifications confirm suitability for standard industrial and commercial applications within the specified operating temperature range of 0°C to 70°C.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MAX173CWG+? A: A valid substitute must match all electrical parameters including 10-bit resolution, 200 kHz sampling rate, single-ended input configuration, SAR architecture with internal reference, and parallel data interface. The mechanical specification requires identical 24-SOIC surface mount packaging with 7.50mm width. Supply voltage requirements (5V, -12V, -15V for both analog and digital) and operating temperature range (0°C to 70°C) must also be identical.

Q: Are there any package compatibility considerations? A: The MAX173CWG+ uses a 24-SOIC package with 0.295" (7.50mm) width. Any substitute part must use the identical package specification to ensure PCB layout compatibility and proper pin alignment. Surface mount assembly equipment settings and reflow profiles remain consistent with this package type.

Q: What is the significance of the internal reference type? A: The internal reference eliminates the need for external reference circuitry, reducing component count and PCB area. Substitute parts must maintain this internal reference architecture to preserve circuit design and performance characteristics.

Q: Does the dual supply voltage capability affect substitution? A: Yes. The MAX173CWG+ supports multiple supply voltage configurations (5V, -12V, -15V for both analog and digital supplies). Substitute parts must support identical voltage options to maintain design flexibility and compatibility with existing power distribution schemes.

Q: What does ROHS3 compliance indicate for this component? A: ROHS3 compliance confirms the part meets Restriction of Hazardous Substances regulations, ensuring lead-free construction and compliance with environmental standards. This certification is maintained across all equivalent parts.
