CAT824SSDI-GT3 Equivalent & Substitute Parts

Part Overview

The CAT824SSDI-GT3 is a Power Management Integrated Circuit (PMIC) functioning as a microprocessor supervisor with push-pull output configuration. This device monitors a single voltage threshold at 2.93V and provides active high/active low reset functionality with a 140ms minimum reset timeout. The component is housed in a 5-TSSOP (SC-70-5, SOT-353) surface mount package.

The CAT824SSDI-GT3 carries an Obsolete product status. Identifying equivalent substitute parts is necessary for design continuity, procurement flexibility, and long-term supply chain management when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the CAT824SSDI-GT3 is determined by strict equivalence across the following critical parameters:

  • Voltage Threshold Monitoring: Single channel at 2.93V
  • Output Type: Push-Pull, Totem Pole configuration
  • Reset Functionality: Active High/Active Low capability
  • Reset Timeout: 140ms minimum duration
  • Operating Temperature Range: -40°C to 85°C
  • Package Type: 5-TSSOP (SC-70-5, SOT-353)
  • Mounting Technology: Surface Mount

The MAX825SEXK+T qualifies as a parametric equivalent because it matches all critical electrical and mechanical specifications. Both devices function identically within the specified operating conditions and physical constraints.

Engineering Selection Recommendations

The MAX825SEXK+T is a direct parametric equivalent to the CAT824SSDI-GT3 across all critical electrical and mechanical specifications. Selection of the MAX825SEXK+T offers the following advantages:

  • Active Product Status: The MAX825SEXK+T maintains Active product status, ensuring ongoing manufacturer support and availability.
  • Regulatory Compliance: The MAX825SEXK+T is ROHS3 Compliant, meeting current environmental and regulatory requirements.
  • Identical Functional Performance: All monitored voltages, output configurations, reset logic, timing parameters, and operating temperature ranges are identical.
  • Pin-Compatible Packaging: Both devices use the 5-TSSOP (SC-70-5, SOT-353) package, enabling direct board-level substitution without layout modifications.
  • Supply Chain Continuity: Current inventory availability (3414 Pcs) of the MAX825SEXK+T supports immediate procurement and production scheduling.

Frequently Asked Questions (FAQ)

Q: Can the MAX825SEXK+T be used as a direct replacement for the CAT824SSDI-GT3 on existing PCBs?

A: Yes. Both devices share identical pinout, package type (5-TSSOP, SC-70-5, SOT-353), and electrical specifications. No circuit modifications or board redesign is required.

Q: Are there differences in the output behavior between these two supervisor ICs?

A: No. Both devices provide identical push-pull, totem pole output configuration with active high/active low reset capability and 140ms minimum reset timeout.

Q: What is the significance of the different packaging formats (unspecified for CAT824SSDI-GT3 versus Tape & Reel for MAX825SEXK+T)?

A: The MAX825SEXK+T is supplied in standard Tape & Reel (TR) format, which is the industry standard for automated assembly processes. This does not affect electrical or mechanical compatibility.

Q: Does the ROHS3 compliance of the MAX825SEXK+T affect its use in existing designs?

A: No. ROHS3 compliance indicates adherence to environmental and hazardous substance restrictions. This is a regulatory advantage and does not impact functional performance or compatibility.

Q: Are there any thermal or reliability differences between the onsemi CAT824SSDI-GT3 and the Analog Devices MAX825SEXK+T?

A: Both devices operate across the identical temperature range (-40°C to 85°C) and share the same Moisture Sensitivity Level (MSL 1, Unlimited). No thermal or reliability trade-offs exist.

Q: What should be considered when transitioning from the obsolete CAT824SSDI-GT3 to the active MAX825SEXK+T?

A: Verify that your procurement and inventory management systems are updated to reflect the new manufacturer (Analog Devices Inc./Maxim Integrated) and part number. Functional validation is not required due to parametric equivalence.
