TPS71256DRCRG4 Equivalent & Substitute Parts

Part Overview

The TPS71256DRCRG4 is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. This dual-output regulator delivers 250mA at a fixed 2.8V output with integrated protection features including over-temperature, reverse polarity, and under-voltage lockout (UVLO). The device is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

The TPS71256DRCRG4 has one parametric equivalent substitute: TPS71256DRCT. Both parts share identical electrical specifications and mechanical characteristics that define substitutability:

Key Parameters for Substitution:

• Output voltage: 2.8V fixed
• Output current: 250mA
• Input voltage maximum: 5.5V
• Dropout voltage: 0.4V @ 500mA
• Package: 10-VFDFN Exposed Pad (10-VSON 3x3)
• Control features: Enable, Power Good
• Protection features: Over Temperature, Reverse Polarity, UVLO
• Operating temperature range: -40°C ~ 125°C

The primary difference between these parts is packaging format: the main part (TPS71256DRCRG4) uses standard packaging, while the substitute (TPS71256DRCT) is supplied in Tape & Reel format. This distinction affects procurement and assembly processes but does not alter electrical or functional performance.

Parameter Comparison

Engineering Selection Recommendations

The TPS71256DRCT is the direct substitute for the obsolete TPS71256DRCRG4. Both parts maintain identical electrical performance and regulatory compliance. The TPS71256DRCT carries Active product status from Texas Instruments, ensuring continued availability and support.

Selection between these parts is determined by procurement requirements:

• TPS71256DRCRG4: Standard packaging format
• TPS71256DRCT: Tape & Reel packaging format for automated assembly

Both parts satisfy ROHS3 compliance and REACH requirements. The MSL rating of 2 (1 Year) applies to both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can TPS71256DRCT replace TPS71256DRCRG4 in existing designs? A: Yes. Both parts are electrically and functionally identical. The only difference is packaging format. No circuit modifications are required.

Q: What is the difference between standard packaging and Tape & Reel? A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly. Standard packaging is used for manual handling or lower-volume applications. The component itself is identical.

Q: Why is TPS71256DRCRG4 listed as obsolete? A: Texas Instruments has transitioned this product line. The TPS71256DRCT remains in active production and is the recommended source for new orders.

Q: Are there any electrical performance differences between these parts? A: No. Output voltage, current rating, dropout voltage, quiescent current, PSRR, and all protection features are identical across both variants.

Q: Do both parts require the same PCB layout and thermal management? A: Yes. Both use the 10-VFDFN Exposed Pad package with identical pinout and thermal characteristics. PCB designs are fully compatible.

Q: What is the MSL rating and why does it matter? A: Both parts have MSL 2 (1 Year) rating. This specifies moisture sensitivity and storage requirements. Components must be stored in controlled humidity environments and used within one year of packaging opening.
