MAX9203ESA Equivalent & Substitute Parts

Part Overview

The MAX9203ESA is a single-channel comparator with integrated latch functionality, designed for TTL-level output applications. It operates across a wide supply voltage range (4.75V to 10.5V single supply, or ±2.375V to ±5.75V dual supply) and is housed in an 8-SOIC surface-mount package. The device is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing production support and design continuity.

Substitute Part Grouping Explanation

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

• Functional Architecture: Single-channel comparator with integrated latch
• Output Logic Level: TTL output type
• Supply Voltage Range: 4.75V to 10.5V (single supply) or ±2.375V to ±5.75V (dual supply)
• Input Offset Voltage: 4mV maximum at ±5V
• Input Bias Current: 5µA maximum at ±5V
• Common-Mode and Power Supply Rejection: 86.02dB CMRR and PSRR
• Package Configuration: 8-SOIC surface-mount package with 0.154" (3.90mm) width
• Operating Temperature Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The MAX9203ESA+ qualifies as a direct substitute based on identical electrical specifications and package footprint. The primary distinction is product status and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the MAX9203ESA+ be used as a direct replacement for the MAX9203ESA?

A: Yes. Both devices are electrically and mechanically identical. They share the same pin configuration, 8-SOIC package footprint, supply voltage range, input offset voltage, bias current, and output characteristics. The primary difference is product status: MAX9203ESA is obsolete, while MAX9203ESA+ is active.

Q: What is the significance of the "+" suffix in MAX9203ESA+?

A: The "+" suffix indicates the active product variant with continued manufacturer support. It does not denote a functional or electrical difference from the base part number.

Q: Are there any package or handling differences between these parts?

A: The MAX9203ESA+ is supplied in Tube packaging format. Both parts have identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The identical 8-SOIC package dimensions (0.154" width, 3.90mm) and pin configuration allow direct PCB footprint compatibility. No design modifications are required.

Q: What supply voltage configurations are supported?

A: Both parts support single-supply operation (4.75V to 10.5V) and dual-supply operation (±2.375V to ±5.75V), providing flexibility for various circuit topologies.
