TPS3780ADRYR Equivalent & Substitute Parts

Part Overview

The TPS3780ADRYR is a dual-voltage supervisor IC manufactured by Texas Instruments, designed for power management applications requiring multi-channel voltage monitoring. This device features an open drain or open collector output with active low reset functionality, operating across an industrial temperature range of -40°C to 125°C. The part is currently in active production status and ROHS3 compliant, making it suitable for modern electronic designs requiring regulatory compliance.

Substitute parts are necessary when the original packaging format (Tape & Reel) is unavailable, when alternative temperature grades are required for specific applications, or when inventory constraints necessitate sourcing from alternative stock configurations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical and mechanical specifications as the TPS3780ADRYR. Substitution is determined by the following critical parameters that remain constant across all variants:

• Base product number: TPS3780
• Functional type: Multi-Voltage Supervisor with 2-channel monitoring
• Electrical characteristics: Adjustable/selectable voltage threshold, open drain/open collector output, active low reset
• Package specification: 6-UFDFN (6-SON 1.45x1)
• Operating temperature range: -40°C to 125°C
• Compliance: ROHS3, REACH Unaffected, EAR99

Variations between substitute parts are limited to packaging format (Tape & Reel, Bulk, or Cut Tape) and temperature grade designation (A, B, C, or D suffix). These variations do not affect electrical performance or mechanical compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

Component selection from the TPS3780 family should be based on three primary criteria: packaging format requirements, temperature grade specifications, and regulatory compliance needs.

For applications requiring Tape & Reel packaging with ROHS3 compliance verification, TPS3780BDRYR, TPS3780CDRYT, and TPS3780DDRYT are direct substitutes for TPS3780ADRYR. These variants maintain identical electrical performance and mechanical compatibility while offering alternative temperature grades (B, C, and D respectively).

TPS3780ADRYT provides the highest inventory availability in Bulk packaging format, suitable for high-volume manufacturing environments where tape packaging is not required. This variant maintains the same temperature grade (A) as the original part.

For applications where Cut Tape packaging is acceptable, TPS3780CDRYR provides an alternative sourcing option with ROHS3 compliance and active production status.

All listed substitutes maintain REACH Unaffected status and EAR99 export classification, ensuring regulatory consistency across supply chain alternatives.

Frequently Asked Questions (FAQ)

Q: Can TPS3780ADRYT (Bulk packaging) be used as a direct substitute for TPS3780ADRYR (Tape & Reel)?

A: Yes. Both parts share identical electrical specifications, temperature grade (A), package type (6-UFDFN), and compliance certifications. The difference is packaging format only. TPS3780ADRYT is suitable for applications where tape packaging is not a requirement.

Q: What is the difference between temperature grades A, B, C, and D in the TPS3780 family?

A: Temperature grade designations (A, B, C, D) represent different temperature qualification levels within the -40°C to 125°C operating range. All variants listed operate across this identical temperature range. Grade selection should be based on application-specific thermal requirements and supplier specifications.

Q: Is TPS3780CDRYR (Cut Tape) mechanically compatible with TPS3780ADRYR (Tape & Reel)?

A: Yes. Both parts use the 6-UFDFN package (6-SON 1.45x1) and are surface mount compatible. Cut Tape and Tape & Reel are alternative delivery formats for the same physical component. Mechanical compatibility is maintained; packaging format differs only in handling and storage.

Q: Are all substitute parts ROHS3 compliant?

A: TPS3780ADRYT lists RoHS status as Vendor Undefined. All other substitutes (TPS3780BDRYR, TPS3780BDRYT, TPS3780CDRYR, TPS3780CDRYT, TPS3780DDRYT) are ROHS3 Compliant. For applications requiring verified ROHS3 compliance, select from the ROHS3 Compliant variants.

Q: Can I substitute TPS3780ADRYR with a different temperature grade variant?

A: Yes. All TPS3780 variants (A, B, C, D grades) maintain identical electrical performance and mechanical specifications. Temperature grade selection should align with application thermal requirements and design specifications. All variants operate across -40°C to 125°C.

Q: What packaging formats are available for TPS3780 supervisors?

A: Available formats include Tape & Reel (TR), Bulk, and Cut Tape (CT). Selection depends on manufacturing process requirements and inventory management practices. All formats contain electrically identical components in 6-UFDFN packages.
