UCD90120RGCT Equivalent & Substitute Parts

Part Overview

The UCD90120RGCT is an active power management integrated circuit (PMIC) supervisor manufactured by Texas Instruments. This 12-channel voltage supervisor operates in the 64-VQFN (9x9) package with exposed pad and provides open drain and push-pull output configurations. The device monitors multiple voltage rails with adjustable/selectable thresholds and delivers active high/active low reset functionality with a 2µs minimum reset timeout. The UCD90120RGCT maintains active product status and is ROHS3 compliant, making it suitable for industrial and commercial power sequencing applications. Equivalent and substitute parts are identified based on matching electrical specifications, package geometry, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UCD90120RGCT are determined by equivalence across the following critical parameters:

• Manufacturer: Texas Instruments (all substitutes)
• Base Product Number: UCD90120 (all substitutes)
• Type: Sequencer with 12-channel voltage monitoring
• Voltage Threshold: Adjustable/Selectable
• Output Configuration: Open Drain, Push-Pull
• Reset Functionality: Active High/Active Low with 2µs minimum timeout
• Operating Temperature Range: -40°C ~ 110°C (TA)
• Package Geometry: 64-VFQFN Exposed Pad (9x9)
• Mounting Type: Surface Mount
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 3 (168 Hours)

Substitute parts differ only in packaging format (Cut Tape vs. Digi-Reel) and specific ECCN/HTSUS classifications, which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—UCD90120RGCR, UCD90120ARGCR, and UCD90120ARGCT—are electrically and mechanically equivalent to the UCD90120RGCT. Selection among these parts is based on:

Product Status: All parts maintain active product status with Texas Instruments, ensuring continued availability and support.

Compliance Certifications: All parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and commercial applications.

Packaging Format: The primary distinction among substitutes is packaging format. The UCD90120RGCT and UCD90120ARGCT are supplied in Cut Tape (CT) format, while UCD90120RGCR and UCD90120ARGCR are supplied in Digi-Reel format. Selection depends on assembly line requirements and tape reel compatibility.

Inventory Availability: Current stock levels vary across substitute parts. UCD90120ARGCR offers the highest inventory (6130 pcs), followed by UCD90120ARGCT (2089 pcs), UCD90120RGCR (1540 pcs), and UCD90120RGCT (1360 pcs).

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the UCD90120RGCT?

A: Yes. All substitute parts share identical electrical specifications, including 12-channel voltage monitoring, adjustable/selectable thresholds, open drain and push-pull output configurations, active high/active low reset functionality, and 2µs minimum reset timeout.

Q: What is the difference between Cut Tape (CT) and Digi-Reel (R) packaging?

A: Cut Tape (CT) packaging supplies components on individual tape segments suitable for manual or small-batch assembly. Digi-Reel (R) packaging supplies components on continuous reels optimized for high-volume automated assembly lines. Electrical and mechanical specifications remain identical.

Q: Can I substitute UCD90120RGCT with UCD90120ARGCR in my design?

A: Yes. Both parts are electrically and mechanically equivalent. The primary consideration is packaging format compatibility with your assembly process. UCD90120ARGCR uses Digi-Reel packaging, while UCD90120RGCT uses Cut Tape packaging.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All parts carry an MSL rating of 3 (168 Hours), indicating they require controlled storage conditions and have a 168-hour floor life after moisture exposure.

Q: Do the substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 110°C (TA).

Q: Which substitute part should I choose based on availability?

A: UCD90120ARGCR offers the highest current inventory at 6130 pcs. If packaging format is not a constraint, this part provides the best availability for immediate procurement.
