Substitute Part Grouping Explanation

Substitution of the MAX9691ESA is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Single-channel comparator with integrated latch
• Output Configuration: Complementary ECL outputs
• Electrical Performance: Input offset voltage, input bias current, output current, quiescent current, CMRR/PSRR specifications, and propagation delay
• Package Compatibility: 8-SOIC surface mount package with identical 0.154" (3.90mm) width
• Environmental Specifications: Operating temperature range -40°C to 85°C
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The MAX9691ESA+ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX9691ESA+ is the direct functional equivalent of the MAX9691ESA. Selection between these parts is determined by availability and product lifecycle status:

MAX9691ESA: Classified as obsolete. Use only when existing inventory must be consumed or when legacy system maintenance requires exact part matching.

MAX9691ESA+: Active product status with current manufacturing support. Recommended for new designs and production replenishment. Identical electrical and mechanical specifications ensure pin-for-pin and functional compatibility. ROHS3 compliance and MSL Level 1 rating confirm suitability for standard manufacturing and storage conditions.

Both parts meet identical performance criteria across all specified electrical parameters and environmental operating conditions.

Frequently Asked Questions (FAQ)
