MAX902ESD Equivalent & Substitute Parts

Part Overview

The MAX902ESD is a dual comparator with integrated latch functionality, designed for TTL-level output applications. Manufactured by Analog Devices Inc./Maxim Integrated, this linear IC operates across single and dual supply voltage ranges (5V ~ 10V, ±2.5V ~ 5V) and is housed in a 14-SOIC surface mount package. The device is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX902ESD is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Dual comparator with integrated latch functionality
• Output Logic Level: TTL output type
• Supply Voltage Range: 5V ~ 10V single supply and ±2.5V ~ 5V dual supply compatibility
• Electrical Performance: Input offset voltage (4mV @ ±5V), input bias current (10µA @ ±5V), quiescent current specifications (8mA, 6mA, 3mA), and common-mode rejection ratio (82.5dB CMRR) and power supply rejection ratio (80dB PSRR)
• Package Specification: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Operating Temperature Range: -40°C ~ 85°C
• Regulatory Compliance: ROHS3 compliance, REACH unaffected status, and MSL 1 rating

The MAX902ESD+ meets all substitution criteria as a direct equivalent, with identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The MAX902ESD+ is the direct substitute for the obsolete MAX902ESD. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications, package configuration, and regulatory compliance status. The primary distinction is product lifecycle status: the MAX902ESD is obsolete while the MAX902ESD+ is active and currently available in production quantities.

For applications currently using the MAX902ESD, transition to the MAX902ESD+ provides continuity of supply without design modification. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The MSL 1 rating indicates unlimited moisture sensitivity protection, suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the MAX902ESD+ be used as a direct replacement for the MAX902ESD?

A: Yes. The MAX902ESD+ is electrically and mechanically identical to the MAX902ESD. All electrical parameters, supply voltage ranges, output characteristics, and package specifications are equivalent. The primary difference is product status: MAX902ESD+ is active and available, while MAX902ESD is obsolete.

Q: Are there any differences in packaging between these parts?

A: No. Both the MAX902ESD and MAX902ESD+ use the 14-SOIC surface mount package with identical 0.154" (3.90mm) width specification. No PCB layout or assembly process modifications are required for substitution.

Q: What is the significance of the "+" suffix in the MAX902ESD+ part number?

A: The "+" suffix indicates the active production variant of the MAX902 base product. It denotes current manufacturing status and availability, distinguishing it from the obsolete MAX902ESD.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the MAX902ESD and MAX902ESD+ are ROHS3 compliant and REACH unaffected. They meet current environmental and regulatory standards for electronic component manufacturing and use.

Q: What is the MSL 1 rating, and does it affect handling?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited moisture sensitivity protection. These parts do not require special moisture control during storage or handling, simplifying logistics and inventory management compared to higher MSL-rated components.
