CAT1832L-G Equivalent & Substitute Parts

Part Overview

The CAT1832L-G is a single-channel power management supervisor IC manufactured by onsemi, designed for reset and power-on reset applications. This device features push-pull/totem pole output configuration and operates across the industrial temperature range of -40°C to 85°C. The CAT1832L-G is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The DS1832+ qualifies as a direct functional equivalent based on the following critical parameters:

Matching Parameters:

• Single-channel voltage monitoring architecture
• Identical voltage threshold options (2.55V, 2.88V)
• Push-pull output configuration
• Active High/Active Low reset logic capability
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package form factor (8-DIP, 0.300", 7.62mm)
• Through-hole mounting compatibility
• Moisture Sensitivity Level 1 (Unlimited)

Substitution Basis: The DS1832+ maintains electrical and mechanical compatibility with the CAT1832L-G across all monitored parameters. Both devices implement single-channel supervisor functionality with selectable voltage thresholds and push-pull output stages. The identical package geometry and pin configuration enable direct socket replacement in existing PCB designs.

Engineering Selection Recommendations

For Obsolete Part Replacement: The DS1832+ is the appropriate selection for applications currently using the CAT1832L-G. The substitute maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring long-term availability and technical support. The DS1832+ carries ROHS3 compliance certification, meeting modern environmental and regulatory requirements.

For New Designs: The DS1832+ should be specified in new designs requiring single-channel supervisor functionality with 2.55V or 2.88V threshold options. Active product status and established supply chain availability provide design continuity and manufacturing reliability.

Compliance Considerations: Both devices carry REACH Unaffected status and EAR99 ECCN classification. The DS1832+ additionally provides ROHS3 compliance, which may be required for applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the DS1832+ directly replace the CAT1832L-G in existing designs? A: Yes. Both devices share identical package geometry (8-DIP), pin configuration, voltage thresholds (2.55V, 2.88V), operating temperature range (-40°C ~ 85°C), and reset logic options (Active High/Active Low). Direct socket replacement is supported.

Q: What is the primary reason for substitution? A: The CAT1832L-G is classified as obsolete. The DS1832+ provides equivalent functionality with active product status and ongoing manufacturer support.

Q: Are there differences in output configuration between these devices? A: Both devices implement push-pull output stages. The CAT1832L-G specifies "Push-Pull, Totem Pole" while the DS1832+ specifies "Push-Pull, Push-Pull." Both configurations are functionally compatible for reset signal generation.

Q: Does the DS1832+ meet current environmental standards? A: Yes. The DS1832+ is ROHS3 compliant and carries REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Are there any package or mounting differences? A: No. Both devices use 8-DIP through-hole packages with identical 0.300" (7.62mm) spacing, enabling direct PCB compatibility.

Q: What voltage thresholds are available? A: Both the CAT1832L-G and DS1832+ support 2.55V and 2.88V threshold options, providing flexibility for different supply voltage monitoring requirements.
