Substitute Part Grouping Explanation

Substitution of the MAX6348XR46-T with the MAX6348XR46+T is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications in the following determinative categories:

• Voltage threshold monitoring: 4.6V
• Output type: Open Drain or Open Collector
• Reset polarity: Active Low
• Reset timeout duration: 100ms Minimum
• Operating temperature range: -40°C ~ 85°C
• Package configuration: SC-70, SOT-323 (SC-70-3)
• Mounting technology: Surface Mount
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The primary distinction between these parts is product status and packaging format. The MAX6348XR46-T is classified as obsolete, while the MAX6348XR46+T maintains active product status and is supplied in Tape & Reel (TR) packaging format, compared to the standard packaging of the original part.

Parameter Comparison

Engineering Selection Recommendations

The MAX6348XR46+T is the appropriate selection for applications currently using or requiring the MAX6348XR46-T.
