MAX9203ESA-T Equivalent & Substitute Parts

Part Overview

The MAX9203ESA-T is a single-channel comparator with integrated latch functionality, designed for TTL-compatible output applications. This device operates across a wide supply voltage range of 4.75V to 10.5V (single supply) or ±2.375V to ±5.75V (dual supply), making it suitable for general-purpose voltage comparison and signal conditioning circuits.

The MAX9203ESA-T is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for legacy systems utilizing this comparator architecture.

Substitute Part Grouping Explanation

Substitution of the MAX9203ESA-T is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Single-channel comparator with integrated latch
• Output Logic Family: TTL-compatible output
• Supply Voltage Range: 4.75V ~ 10.5V (single) or ±2.375V ~ 5.75V (dual)
• Input Offset Voltage: 4mV maximum at ±5V
• Input Bias Current: 5µA maximum at ±5V
• Common-Mode Rejection Ratio: 86.02dB typical
• Power Supply Rejection Ratio: 86.02dB typical
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-SOIC surface mount
• Compliance Standards: ROHS3 compliant, REACH unaffected

The MAX9203ESA+T qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary distinction is packaging format: the substitute part is supplied in Tape & Reel (TR) format versus the original tube packaging, and carries an active product status.

Parameter Comparison

Engineering Selection Recommendations

The MAX9203ESA+T is a direct functional equivalent to the MAX9203ESA-T. Both parts share identical electrical specifications, the same 8-SOIC package footprint, and equivalent thermal characteristics across the specified operating temperature range.

The primary advantage of selecting the MAX9203ESA+T is its active product status with Analog Devices Inc./Maxim Integrated, ensuring continued availability and manufacturing support. The substitute part maintains full ROHS3 compliance and REACH compliance status, meeting current regulatory requirements for electronic components.

Packaging format differs between the two parts: the original MAX9203ESA-T is supplied in tube packaging, while the MAX9203ESA+T is supplied in Tape & Reel format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)
