Substitute Part Grouping Explanation

Substitution eligibility for the MAX158BCWI is determined by strict equivalence across the following critical parameters: 8-bit resolution, 8 single-ended input channels, 400 kHz sampling rate, flash architecture, parallel data interface, MUX-S/H-ADC configuration, internal reference, 5V analog and digital supply requirements, 28-SOIC package, and 0°C to 70°C operating temperature range.

The MAX158BCWI+ qualifies as a direct substitute based on complete electrical and mechanical parameter alignment. Both devices share identical functional specifications, pinout compatibility, and package footprint. The primary distinction lies in product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX158BCWI+ is the direct equivalent for the obsolete MAX158BCWI. Both devices are electrically and mechanically identical, with pinout and footprint compatibility confirmed across all specified parameters.

Selection between these parts should be based on the following criteria:

For new designs and ongoing production requiring regulatory compliance, the MAX158BCWI+ is the appropriate choice. This device carries Active product status and ROHS3 compliance certification, meeting current environmental and supply chain requirements.

For legacy system maintenance where existing inventory of MAX158BCWI units is available, continued use of the original part number is permissible provided supply remains available. However, transition to MAX158BCWI+ is recommended to ensure long-term component availability and compliance alignment.
