UCD9090RGZR Equivalent & Substitute Parts

Part Overview

The UCD9090RGZR is an active supervisor integrated circuit designed for power management applications requiring multi-channel voltage monitoring and sequencing. This 10-channel supervisor operates across an extended temperature range of -40°C to 110°C and is housed in a 48-pin VQFN package with exposed pad. The device features adjustable/selectable voltage thresholds, active-low reset output, and a 2µs minimum reset timeout, making it suitable for complex power supply sequencing in industrial and high-reliability applications. As an active product with full RoHS3 compliance and REACH unaffected status, the UCD9090RGZR remains in production. Equivalent parts are identified to support supply chain flexibility and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCD9090RGZR is determined by strict equivalence across the following critical parameters:

• Identical 10-channel voltage monitoring capability
• Matching adjustable/selectable voltage threshold configuration
• Active-low reset output with 2µs minimum reset timeout
• Identical 48-VFQFN exposed pad package and surface mount technology
• Extended operating temperature range of -40°C to 110°C
• Equivalent RoHS3 compliance and REACH unaffected status
• Matching MSL rating of 3 (168 Hours)

The UCD9090ARGZR meets all substitution criteria as a direct equivalent from the same manufacturer, differing only in internal device binning or qualification level while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the UCD9090RGZR and UCD9090ARGZR are active products from Texas Instruments with identical compliance certifications. Selection between these parts should be based on availability and procurement lead times. Both devices maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance for industrial and commercial applications. The MSL rating of 3 (168 Hours) applies uniformly across both parts, requiring standard moisture control during storage and handling. No functional or electrical differences exist between these supervisors; they are direct equivalents suitable for interchangeable use in power management sequencing applications.

Frequently Asked Questions (FAQ)
