TPS2559DRCT Equivalent & Substitute Parts

Part Overview

The TPS2559DRCT is an active power switch IC manufactured by Texas Instruments, classified as a Power Management (PMIC) device. It functions as a 1:1 N-Channel power switch/driver with high-side output configuration, rated for 5.5A maximum output current and designed for load voltage ranges of 2.5V to 6.5V. The device is currently in active product status with 4900 units available in new original inventory. Alternative equivalent parts are necessary to support supply chain flexibility, extended lead times, or regional availability requirements.

Key Parameters

Substitute Part Grouping Explanation

The TPS2559DRCR qualifies as a parametric equivalent to the TPS2559DRCT based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Output current rating: 5.5A maximum
• Load voltage range: 2.5V ~ 6.5V
• On-resistance (Rds On): 13mOhm typical
• Package type: 10-VFDFN Exposed Pad (Surface Mount)
• Output configuration: High-side N-Channel, 1:1 ratio
• Interface type: On/Off control
• Fault protection features: Current Limiting (Adjustable), Over Temperature, UVLO
• Operating temperature range: -40°C ~ 125°C (TJ)

Both parts share the same base product number (TPS2559) and are manufactured by Texas Instruments. The difference between DRCT and DRCR designations reflects packaging reel format variations (Cut Tape vs. Digi-Reel®) rather than functional or electrical differences.

Parameter Comparison

Engineering Selection Recommendations

Both TPS2559DRCT and TPS2559DRCR are functionally equivalent power switch ICs suitable for direct substitution in applications requiring high-side N-Channel switching at 5.5A with load voltages between 2.5V and 6.5V. Selection between these parts should be based on packaging and supply availability:

• TPS2559DRCT: Cut Tape (CT) packaging format, 4900 units in stock
• TPS2559DRCR: Digi-Reel® packaging format, 9300 units in stock

Both parts maintain active product status from Texas Instruments and carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99). No functional performance differences exist between the two variants. PCB layout, thermal management, and circuit design considerations remain unchanged when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can TPS2559DRCR be used as a direct replacement for TPS2559DRCT?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format (Cut Tape vs. Digi-Reel®). No circuit modifications or design changes are required.

Q: What is the difference between DRCT and DRCR designations?

A: The suffix indicates the reel packaging format. DRCT denotes Cut Tape packaging, while DRCR denotes Digi-Reel® packaging. Electrical specifications and die characteristics are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts have identical thermal characteristics, on-resistance (13mOhm typical), current ratings (5.5A), and operating temperature ranges (-40°C to 125°C).

Q: Do both parts support the same fault protection features?

A: Yes. Both TPS2559DRCT and TPS2559DRCR include adjustable current limiting, over-temperature protection, and UVLO (Under-Voltage Lock-Out) functionality.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and EAR99 export classification. MSL rating is 2 (1 Year) for both variants.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, provided the assembly equipment is configured to handle the respective packaging format. Cut Tape (DRCT) and Digi-Reel® (DRCR) formats require different feeder configurations but produce identical assembled results.
