Substitute Part Grouping Explanation

Substitution of the MAX901BCSE is determined by strict equivalence across the following critical parameters:

• Number of comparator elements: 4
• Output type: TTL
• Supply voltage range: 5V ~ 10V (single), ±2.5V ~ 5V (dual)
• Input offset voltage: 4mV @ ±5V
• Input bias current: 10µA @ ±5V
• Quiescent current specifications: 15mA, 12mA, 6mA
• Common-mode rejection ratio: 82.5dB
• Power supply rejection ratio: 80dB
• Package type: 16-SOIC surface mount
• Operating temperature range: 0°C ~ 70°C

The MAX901BCSE+ meets all these electrical and mechanical parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX901BCSE+ is the direct functional equivalent of the MAX901BCSE. Both devices are pin-compatible and electrically identical across all specified parameters. The primary distinction is product status: the MAX901BCSE is obsolete, while the MAX901BCSE+ is active and currently manufactured.

For new designs or production continuity, the MAX901BCSE+ is the appropriate selection. The MAX901BCSE+ offers ROHS3 compliance, whereas the original MAX901BCSE is RoHS non-compliant. Both devices maintain identical electrical performance, supply voltage ranges, and thermal operating specifications. The 16-SOIC package geometry and surface-mount configuration remain unchanged, ensuring mechanical compatibility in existing PCB layouts.
