MAX902CSD-T Equivalent & Substitute Parts

Part Overview

The MAX902CSD-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 MAX902CSD-T is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and production continuity.

Substitute Part Grouping Explanation

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

• Functional Type: Dual comparator with integrated latch
• Output Configuration: TTL-level output
• Supply Voltage Range: 5V ~ 10V (single supply), ±2.5V ~ 5V (dual supply)
• Electrical Performance: Input offset voltage 4mV @ ±5V, input bias current 10µA @ 5V, quiescent current specifications (8mA, 6mA, 3mA)
• Signal Integrity: CMRR 82.5dB, PSRR 80dB
• Package Compatibility: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Environmental Compliance: ROHS3 compliant, REACH unaffected, MSL 1

The substitute part must maintain identical electrical specifications, package dimensions, and pin configuration to ensure direct replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The MAX902CSD+T is the direct functional equivalent of the MAX902CSD-T. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, package geometry, and pin configuration. The primary distinction is product status: the MAX902CSD-T is obsolete, while the MAX902CSD+T maintains active production status.

For new designs and production applications requiring dual TTL comparators with integrated latch functionality, the MAX902CSD+T is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The packaging difference (tube versus tape & reel) reflects standard distribution formats and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX902CSD+T replace MAX902CSD-T in existing designs? A: Yes. The MAX902CSD+T is electrically and mechanically identical to the MAX902CSD-T. Pin configuration, package dimensions (14-SOIC, 0.154" width), and all electrical parameters are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between the two part numbers? A: The primary difference is product status and packaging format. MAX902CSD-T is obsolete and supplied in tube packaging. MAX902CSD+T is active production and supplied in tape & reel format. Electrical specifications and package geometry are identical.

Q: Are there any compliance or certification differences? A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited moisture sensitivity level). Regulatory and environmental certifications are equivalent.

Q: What supply voltages are supported? A: Both devices support single supply operation (5V ~ 10V) and dual supply operation (±2.5V ~ 5V). Circuit design must specify the intended supply configuration.

Q: Is the 14-SOIC package compatible with existing PCB layouts? A: Yes. Both parts use identical 14-SOIC surface mount packages with 0.154" (3.90mm) width. PCB footprints and reflow profiles remain unchanged.

Q: What is the operating temperature range? A: Both devices operate across 0°C ~ 70°C. Applications requiring extended temperature ranges require alternative device selection.
