TPS71229DRCTG4 Equivalent & Substitute Parts

Part Overview

The TPS71229DRCTG4 is a linear voltage regulator IC from Texas Instruments designed for positive adjustable (fixed) output applications. This dual-output 250mA regulator operates in a compact 10-VSON (3x3) package with integrated enable and power good control features. The main part number is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and design requirements. Parametric equivalents maintain identical electrical and mechanical specifications while offering different packaging configurations or active product status.

Substitute Part Grouping Explanation

Substitute parts for the TPS71229DRCTG4 are identified as parametric equivalents based on identical electrical and mechanical specifications. The substitution logic is determined by the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable/Fixed)
• Number of regulators (2)
• Voltage ratings (Input Max: 5.5V, Output Min/Fixed: 1.2V/2.8V, Output Max: 5.5V)
• Current specifications (Output: 250mA, Quiescent: 250 µA, Supply Max: 600 µA)
• Dropout voltage (0.4V @ 500mA)
• Control and protection features (Enable, Power Good, Over Temperature, Reverse Polarity, UVLO)
• Operating temperature range (-40°C ~ 125°C)
• Package type (10-VFDFN Exposed Pad, 10-VSON 3x3)
• Compliance certifications (ROHS3, REACH Unaffected)

The identified substitutes (TPS71229DRCR and TPS71229DRCT) maintain all electrical and mechanical parameters while differing only in packaging configuration (Tape & Reel) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

Both TPS71229DRCR and TPS71229DRCT are direct parametric equivalents to the TPS71229DRCTG4. Selection between these substitutes should be based on the following factors:

Product Status: TPS71229DRCR and TPS71229DRCT are both active products, whereas the main part number is discontinued. Active product status ensures ongoing availability and manufacturer support.

Packaging Configuration: The main part (TPS71229DRCTG4) is supplied in tube packaging. Both substitute parts are supplied in Tape & Reel (TR) configuration. This difference affects handling, storage, and automated assembly processes but does not impact electrical or mechanical compatibility.

Compliance and Certifications: All three part numbers maintain identical ROHS3 compliance, REACH unaffected status, and MSL rating (2, 1 Year). No compliance degradation occurs with either substitute.

Inventory Availability: TPS71229DRCR has 988 pieces in stock, and TPS71229DRCT has 736 pieces in stock, compared to 884 pieces for the discontinued main part number.

For new designs or production requiring long-term component availability, either TPS71229DRCR or TPS71229DRCT is suitable. Selection between the two substitutes should be based on packaging requirements and inventory availability at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Are TPS71229DRCR and TPS71229DRCT electrically identical to TPS71229DRCTG4?

A: Yes. All three part numbers share identical electrical specifications including voltage ratings, current capabilities, dropout voltage, control features, protection features, and operating temperature range. They are parametric equivalents.

Q: What is the difference between TPS71229DRCTG4 and its substitutes?

A: The primary differences are product status and packaging configuration. TPS71229DRCTG4 is discontinued and supplied in tube packaging. TPS71229DRCR and TPS71229DRCT are active products supplied in Tape & Reel configuration. All electrical and mechanical specifications remain identical.

Q: Can I use TPS71229DRCR or TPS71229DRCT as a direct replacement in existing designs?

A: Yes, both parts are direct replacements from an electrical and mechanical standpoint. The 10-VSON (3x3) package and pin configuration are identical. The only consideration is the packaging format change from tube to Tape & Reel, which affects procurement and assembly processes but not circuit functionality.

Q: Does the Tape & Reel packaging affect the component's performance?

A: No. Tape & Reel packaging is a supply format that affects handling and automated assembly processes. The component itself, once removed from the tape and reel, is identical to the tube-packaged version in all electrical and mechanical characteristics.

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

A: No. All three part numbers maintain identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level (MSL) rating of 2 (1 Year). No compliance degradation occurs with either substitute.

Q: Which substitute should I choose for new production?

A: Both TPS71229DRCR and TPS71229DRCT are suitable for new production. Selection should be based on packaging requirements (Tape & Reel is standard for automated assembly) and current inventory availability. Both are active products with ongoing manufacturer support.
