CAT1025WI-30-G Equivalent & Substitute Parts

Part Overview

The CAT1025WI-30-G is a supervisor integrated circuit with 2K EEPROM functionality, manufactured by onsemi. It operates as a simple reset/power-on reset device with open drain or open collector output configuration. The device monitors a single voltage channel with a 3V threshold and provides a 130ms minimum reset timeout.

The CAT1025WI-30-G is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT1025WI-30-G is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring: Single channel with 3V threshold
• Output Configuration: Open drain or open collector topology
• Reset Behavior: Active high/active low capability
• Reset Timeout: 130ms minimum duration
• Operating Temperature Range: -40°C to 85°C
• Package: 8-SOIC form factor with identical physical dimensions
• Mounting: Surface mount technology

The CAT1023WI-30-G meets all these criteria and qualifies as a parametric equivalent. Both devices share identical electrical specifications, thermal operating range, and mechanical packaging. The primary distinction is product status: the CAT1023WI-30-G is active in production, whereas the CAT1025WI-30-G is obsolete.

Parameter Comparison
