MAX902CSD Equivalent & Substitute Parts

Part Overview

The MAX902CSD is a dual comparator with integrated latch functionality, designed for TTL-level output applications. This linear integrated circuit 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 MAX902CSD is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX902CSD is determined by strict equivalence across the following critical parameters:

• Dual comparator architecture with integrated latch function
• TTL output type
• Supply voltage range: 5V ~ 10V (single), ±2.5V ~ 5V (dual)
• Input offset voltage: 4mV @ ±5V maximum
• Input bias current: 10µA @ ±5V maximum
• Quiescent current specifications: 8mA, 6mA, 3mA
• Common-mode rejection ratio: 82.5dB minimum
• Power supply rejection ratio: 80dB minimum
• Operating temperature range: 0°C ~ 70°C
• Package: 14-SOIC surface mount
• Pin-for-pin compatibility

The MAX902CSD+ is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The MAX902CSD+ is the direct equivalent for the obsolete MAX902CSD. Selection between these parts is determined by application requirements and regulatory compliance:

For new designs and production requiring regulatory compliance, the MAX902CSD+ is the appropriate selection. This part maintains active product status with Analog Devices Inc./Maxim Integrated and carries ROHS3 compliance certification, meeting current environmental and regulatory standards.

The MAX902CSD remains available for legacy system maintenance and repair applications where existing inventory exists. However, the obsolete status indicates no further manufacturing or support from the original manufacturer.

Both parts are electrically and mechanically identical across all specified parameters, ensuring direct substitution without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can MAX902CSD+ directly replace MAX902CSD in existing designs?

A: Yes. The MAX902CSD+ is electrically and mechanically equivalent to the MAX902CSD. All electrical parameters, supply voltage ranges, output characteristics, and package specifications are identical. Direct substitution is possible without circuit modification.

Q: What is the primary difference between MAX902CSD and MAX902CSD+?

A: The MAX902CSD+ is the active production equivalent. Key differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant). Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: Both parts use the 14-SOIC surface mount package with identical dimensions (0.154" width, 3.90mm). The MAX902CSD+ is supplied in Tube packaging, while the MAX902CSD packaging specification is not detailed. This does not affect electrical compatibility or board-level integration.

Q: Is the MAX902CSD+ suitable for new product designs?

A: Yes. The MAX902CSD+ is the recommended selection for new designs. It carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Q: What is the moisture sensitivity level for both parts?

A: Both the MAX902CSD and MAX902CSD+ carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
