TPS2105DBVR Equivalent & Substitute Parts

Part Overview

The TPS2105DBVR is an OR Controller Source Selector Switch manufactured by Texas Instruments, classified as a Power Management (PMIC) device. This integrated circuit functions as a 2:1 source selector switch with N and P-Channel FET architecture, designed for applications requiring power source selection in handheld and mobile devices. The device is currently in active production status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when packaging or supply chain requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS2105DBVR are determined by equivalence in the following critical parameters:

• Manufacturer: Texas Instruments (same manufacturer ensures design and performance consistency)
• Base Product Number: TPS2105 (identical core device architecture)
• FET Type: N and P-Channel (functional topology requirement)
• Ratio - Input:Output: 2:1 (electrical configuration)
• Current - Output (Max): 500mA, 100mA (performance specification)
• Current - Supply: 18 µA (power consumption)
• Voltage - Supply: 2.7V ~ 5.5V (operating range)
• Operating Temperature: -40°C ~ 85°C (thermal specification)
• Package / Case: SC-74A, SOT-753 (physical footprint)
• Supplier Device Package: SOT-23-5 (pin configuration)

The primary distinction between the main part and substitute parts is the packaging format: Cut Tape (CT) & Digi-Reel® versus Tape & Reel (TR). This difference affects supply chain logistics and handling but does not alter electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS2105DBVR and TPS2105DBVT are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and supply chain requirements:

• TPS2105DBVR (Cut Tape & Digi-Reel®) is suitable for applications requiring smaller quantity orders or mixed component sourcing.
• TPS2105DBVT (Tape & Reel) is appropriate for high-volume manufacturing environments with automated pick-and-place assembly processes.

Both parts maintain full compliance with RoHS3 and REACH regulations, ensuring regulatory compatibility across all applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can TPS2105DBVT be used as a direct replacement for TPS2105DBVR in PCB assembly?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. TPS2105DBVT is supplied in Tape & Reel format, while TPS2105DBVR is supplied in Cut Tape & Digi-Reel® format. PCB footprint, pin configuration, and electrical performance are identical.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) & Digi-Reel® packaging is used for smaller quantities and manual or semi-automated assembly. Tape & Reel (TR) packaging is designed for high-speed automated assembly lines. Both formats contain the same component on SOT-23-5 package.

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

A: No. Both parts operate within the same voltage range (2.7V ~ 5.5V), supply current (18 µA), output current (500mA, 100mA), and temperature range (-40°C ~ 85°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both TPS2105DBVR and TPS2105DBVT are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited).

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing volume and assembly process. For automated high-volume production, TPS2105DBVT (Tape & Reel) is standard. For lower volumes or mixed sourcing, TPS2105DBVR (Cut Tape & Digi-Reel®) may be more practical.
