TPS3779ADRYR Equivalent & Substitute Parts

Part Overview

The TPS3779ADRYR is a multi-voltage supervisor IC manufactured by Texas Instruments, designed for power management applications requiring dual-channel voltage monitoring with push-pull totem pole output configuration. This device operates across the industrial temperature range of -40°C to 125°C and is housed in a compact 6-SON (1.45x1) surface mount package. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on identical electrical specifications and mechanical compatibility while accommodating different packaging formats and manufacturing variants.

Substitute Part Grouping Explanation

Substitute parts for the TPS3779ADRYR are qualified based on strict parametric equivalence across all electrical and mechanical specifications. The substitution criteria are:

Identical device type: Multi-Voltage Supervisor with 2-channel monitoring
Identical voltage threshold capability: Adjustable/Selectable
Identical output configuration: Push-Pull, Totem Pole
Identical reset logic: Active Low
Identical operating temperature range: -40°C to 125°C
Identical package footprint: 6-UFDFN (6-SON 1.45x1)
Identical compliance certifications: RoHS3, REACH Unaffected
Identical moisture sensitivity: MSL 1

Substitutes differ only in packaging format (Cut Tape vs. Tape & Reel) and manufacturing variant designations (A, B, C, D series), which do not affect electrical performance or mechanical compatibility. All substitute parts maintain active product status and full regulatory compliance.

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications and mechanical compatibility with the TPS3779ADRYR. Selection between equivalent parts should be based on:

Packaging Format Requirements: The TPS3779ADRYR is supplied in Cut Tape format. If Tape & Reel packaging is required for automated assembly processes, any of the TR-packaged variants (TPS3779ADRYT, TPS3779BDRYT, TPS3779CDRYR, TPS3779CDRYT, TPS3779DDRYT) provide direct functional equivalence.

Inventory Availability: All substitute parts are in active production with confirmed stock levels. TPS3779ADRYT offers the highest inventory availability at 2192 pieces, followed by TPS3779DDRYT at 1404 pieces.

Regulatory Compliance: All parts carry identical RoHS3 compliance and REACH Unaffected status, suitable for applications requiring full regulatory certification.

Manufacturing Variant Designation: The letter designations (A, B, C, D) in the part number represent manufacturing variants that do not affect functional performance or pin compatibility. These variants are interchangeable from an engineering perspective.

Frequently Asked Questions (FAQ)

Q: Can TPS3779ADRYT be used as a direct replacement for TPS3779ADRYR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: TPS3779ADRYR uses Cut Tape while TPS3779ADRYT uses Tape & Reel. Pin configuration, electrical specifications, and performance characteristics are identical.

Q: What is the difference between the A, B, C, and D variants in the part number?

A: These letters represent manufacturing variants assigned by Texas Instruments. They do not indicate functional differences, performance variations, or specification changes. All variants meet identical electrical and mechanical requirements and are fully interchangeable.

Q: Are all substitute parts suitable for the same PCB footprint?

A: Yes. All listed parts use the 6-UFDFN package with identical 6-SON (1.45x1) footprint dimensions. No PCB layout modifications are required when substituting between any of these parts.

Q: Which substitute part should I select for high-volume production?

A: For automated assembly, select a Tape & Reel packaged variant. TPS3779ADRYT provides the highest inventory availability. For manual assembly or lower volumes, Cut Tape format (TPS3779ADRYR) may be more cost-effective.

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

A: Yes. All parts operate across -40°C to 125°C junction temperature range, suitable for industrial and extended temperature applications.

Q: Are there any compliance or certification differences between substitute parts?

A: No. All parts carry identical RoHS3 compliance, REACH Unaffected status, MSL 1 rating, and active product status. No additional qualification or testing is required when substituting between any listed parts.
