MAX902ESD-T Equivalent & Substitute Parts

Part Overview

The MAX902ESD-T is a dual comparator with integrated latch functionality, designed for TTL-level output applications. This device operates across a wide supply voltage range (5V ~ 10V single supply, ±2.5V ~ 5V dual supply) and is housed in a 14-SOIC surface mount package. The MAX902ESD-T is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity.

Substitute Part Grouping Explanation

Substitution of the MAX902ESD-T is determined by strict equivalence across the following critical parameters:

• Comparator Configuration: 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 capability
• Input Offset Voltage: Maximum 4mV @ ±5V
• Input Bias Current: Maximum 10µA @ ±5V
• Quiescent Current: 8mA, 6mA, 3mA specifications
• Common Mode and Power Supply Rejection: 82.5dB CMRR and 80dB PSRR
• Operating Temperature Range: -40°C ~ 85°C
• Package: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, MSL Level 1

The MAX902ESD+T meets all these criteria and is the direct active equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX902ESD+T is the direct active equivalent for the obsolete MAX902ESD-T. Both parts share identical electrical specifications, package configuration, and regulatory compliance status. The MAX902ESD+T maintains ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with current manufacturing and environmental standards. Selection of the MAX902ESD+T eliminates obsolescence risk while preserving full functional and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

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

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 The primary difference is product status: MAX902ESD+T is active, while MAX902ESD-T is obsolete.

Q: Are there any differences in the 14-SOIC package between these parts?

A: No. Both parts use the identical 14-SOIC package with 0.154" (3.90mm) width. Pin configuration, lead spacing, and mounting requirements are identical, enabling direct PCB-level substitution without layout modifications.

Q: What is the significance of the part number suffix change from "-T" to "+T"?

A: The suffix change reflects a packaging or manufacturing revision code assigned by Analog Devices Inc./Maxim Integrated. The electrical and functional specifications remain unchanged. Both suffixes denote the same 14-SOIC package configuration.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the MAX902ESD-T and MAX902ESD+T are ROHS3 compliant and REACH unaffected. Both carry MSL Level 1 rating, indicating unlimited moisture sensitivity protection requirements.

Q: What inventory considerations should be evaluated?

A: The MAX902ESD-T has 829 pieces in stock (obsolete status). The MAX902ESD+T has 2700 pieces in stock (active status). For new designs or production continuity, the MAX902ESD+T is the recommended selection due to active product status and higher inventory availability.
