TPS3307-18DR Equivalent & Substitute Parts

Part Overview

The TPS3307-18DR is a multi-voltage supervisor IC manufactured by Texas Instruments, designed for power management applications requiring real-time voltage monitoring across three channels. This device operates as a Push-Pull, Totem Pole output supervisor with Active High/Active Low reset capability and a 140ms minimum reset timeout. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits functional alternatives that maintain identical electrical and mechanical specifications.

Engineering Selection Recommendations

All three parts listed maintain identical electrical specifications and mechanical compatibility. Selection between TPS3307-18DR and its Analog Devices equivalents (ADM13307-18ARZ and ADM13307-18ARZ-RL7) is determined by availability and packaging requirements rather than functional performance.

Product Status: All parts are in active production with confirmed inventory availability.

Compliance: All parts meet RoHS3 requirements and REACH unaffected status, suitable for regulated applications.

Packaging Considerations:

TPS3307-18DR: Cut Tape and Digi-Reel® formats support both manual and automated assembly workflows
ADM13307-18ARZ: Tube packaging accommodates manual component handling and smaller volume requirements
ADM13307-18ARZ-RL7: Tape & Reel format optimizes high-volume automated assembly processes

No additional testing or verification is required when substituting between these parts, as all electrical and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can ADM13307-18ARZ replace TPS3307-18DR in existing designs? A: Yes. Both parts are functionally identical across all electrical specifications, voltage thresholds, output configuration, reset logic, and operating temperature range. Direct substitution is valid without circuit modification.

Q: What is the difference between ADM13307-18ARZ and ADM13307-18ARZ-RL7? A: The parts are electrically identical. The difference is packaging format only. ADM13307-18ARZ is supplied in Tube packaging, while ADM13307-18ARZ-RL7 is supplied in Tape & Reel format. Selection depends on assembly process requirements and volume.

Q: Are there any pin compatibility concerns? A: No. All three parts use the 8-SOIC package with identical pinout and mechanical dimensions (0.154", 3.90mm width). PCB footprints and assembly processes remain unchanged.

Q: Do these parts require different handling or storage procedures? A: No. All parts share MSL 1 (Unlimited) moisture sensitivity rating, meaning standard component storage conditions apply uniformly across all three options.

Q: Are there compliance or certification differences? A: No. All parts are RoHS3 compliant, REACH unaffected, and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).

Q: Which part should be selected for high-volume production? A: ADM13307-18ARZ-RL7 in Tape & Reel format is optimized for automated assembly at production scale. TPS3307-18DR in Cut Tape or Digi-Reel® format supports flexible volume requirements.
