TPS75615KTTR Equivalent & Substitute Parts

Part Overview

The TPS75615KTTR is a linear voltage regulator IC from Texas Instruments designed for positive fixed 1.5V output at 5A in a TO-263 (DDPAK-5) surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing design support and procurement. The part provides integrated protection features including over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) protection, making it suitable for applications requiring regulated low-voltage power delivery with thermal and electrical safeguards.

Substitute Part Grouping Explanation

Substitution for the TPS75615KTTR is based on strict electrical and mechanical parameter matching within the TPS75615 product family. The following criteria determine valid equivalence:

Critical Matching Parameters:

  • Output voltage: 1.5V fixed
  • Maximum output current: 5A
  • Maximum input voltage: 5.5V
  • Quiescent current: 200 µA
  • PSRR: 60dB (100Hz)
  • Protection features: Over Current, Over Temperature, Reverse Polarity, UVLO
  • Operating temperature range: -40°C ~ 125°C
  • Package: TO-263 (DDPAK-5)
  • Compliance: ROHS3, REACH Unaffected

The substitute parts identified (TPS75615KTTT and TPS75615KTTTG3) are parametric equivalents sharing identical electrical specifications and mechanical form factor. The primary distinction is product status and packaging configuration.

Engineering Selection Recommendations

Both TPS75615KTTT and TPS75615KTTTG3 are direct parametric equivalents to the obsolete TPS75615KTTR. Selection between active alternatives is determined by procurement and supply chain requirements:

TPS75615KTTT is recommended for standard procurement where tape and reel packaging is acceptable for automated assembly processes.

TPS75615KTTTG3 provides an alternative active source with identical electrical and mechanical specifications, also supplied in tape and reel format.

Both substitute parts maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original part. The transition from tube packaging (TPS75615KTTR) to tape and reel packaging (both substitutes) reflects current manufacturing standards and does not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Are TPS75615KTTT and TPS75615KTTTG3 direct replacements for TPS75615KTTR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (1.5V), output current (5A), protection features, and operating temperature range. The primary difference is product status (active vs. obsolete) and packaging format (tape and reel vs. tube).

Q: What is the difference between TPS75615KTTT and TPS75615KTTTG3?

A: Both parts share identical electrical and mechanical parameters. The distinction is in inventory availability and supply chain sourcing. Both are supplied in tape and reel packaging and are classified as active products.

Q: Can I use tape and reel packaged parts (TPS75615KTTT, TPS75615KTTTG3) in place of the tube packaged TPS75615KTTR?

A: Yes. Tape and reel packaging is compatible with automated pick-and-place assembly equipment. The electrical performance and thermal characteristics remain unchanged. Verify that your assembly process supports tape and reel component handling.

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

A: No. All three parts maintain identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 2, 1 Year). Regulatory and environmental compliance is equivalent across all variants.

Q: What parameters must remain constant for substitution validity?

A: Output voltage (1.5V fixed), maximum output current (5A), maximum input voltage (5.5V), quiescent current (200 µA), PSRR (60dB at 100Hz), protection features (over-current, over-temperature, reverse polarity, UVLO), operating temperature range (-40°C to 125°C), and package type (TO-263 DDPAK-5) must all remain unchanged for direct substitution.
