MAX933CSA-T Equivalent & Substitute Parts

Part Overview

The MAX933CSA-T is a dual comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This CMOS/TTL output comparator operates across a wide supply voltage range (2.5V to 11V single supply, ±1.25V to 5.5V dual supply) and is housed in an 8-SOIC surface mount package. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the MAX933CSA-T is determined by strict equivalence across the following critical parameters:

  • Functional Configuration: Dual comparator with integrated voltage reference
  • Output Stage: CMOS/TTL compatible output
  • Supply Voltage Range: 2.5V to 11V (single supply) and ±1.25V to 5.5V (dual supply)
  • Electrical Performance: Input offset voltage (10mV @ 5V), quiescent current (6µA max), propagation delay (12µs max), hysteresis (50mV)
  • Package Specification: 8-SOIC surface mount package with 0.154" width (3.90mm)
  • Thermal Range: 0°C to 70°C operating temperature

The MAX933CSA+T qualifies as a direct substitute based on identical electrical specifications and package configuration. The distinction between these part numbers relates exclusively to packaging format (tube versus tape & reel) and product status (obsolete versus active).

Engineering Selection Recommendations

The MAX933CSA+T is the direct functional equivalent of the MAX933CSA-T. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, performance characteristics, and package geometry. The primary distinction is product status: the MAX933CSA-T is obsolete, while the MAX933CSA+T maintains active status with higher inventory availability.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and long-term storage capability. Selection between these variants should be based on packaging requirements (tube versus tape & reel format) and supply chain availability. The active status of the MAX933CSA+T makes it the preferred choice for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Are MAX933CSA-T and MAX933CSA+T electrically identical?

A: Yes. Both devices are manufactured by Analog Devices Inc./Maxim Integrated with identical electrical specifications, including supply voltage range, input offset voltage, quiescent current, propagation delay, and hysteresis characteristics.

Q: What is the difference between these part numbers?

A: The difference is limited to packaging format and product status. MAX933CSA-T uses tube packaging and is classified as obsolete. MAX933CSA+T uses tape & reel packaging and maintains active product status.

Q: Can MAX933CSA+T be used as a direct replacement in existing designs?

A: Yes. The MAX933CSA+T is a direct substitute. Both parts use the 8-SOIC surface mount package with identical pinout, electrical performance, and operating characteristics. No circuit modifications are required.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating. Regulatory and environmental compliance is equivalent.

Q: Which part should be selected for new production?

A: The MAX933CSA+T is recommended for new production due to its active product status and higher inventory availability. Tape & reel packaging is standard for automated assembly processes.
