TPS2012DRG4 Equivalent & Substitute Parts

Part Overview

The TPS2012DRG4 is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 1:1 N-Channel configuration, rated for 1A maximum output current. This component is designed for high-side switching applications in systems requiring 2.7V to 5.5V load voltage operation.

The TPS2012DRG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS2012DRG4 must maintain electrical and mechanical compatibility based on the following critical parameters:

• Package / Case: 8-SOIC form factor (identical physical footprint required)
• Output Configuration: High Side switching topology
• Output Type: N-Channel
• Voltage - Load: 2.7V ~ 5.5V operating range
• Current - Output (Max): 1A rated capacity
• Switch Type: General Purpose
• Mounting Type: Surface Mount
• Operating Temperature: -40°C ~ 125°C (TJ)
• RoHS Status: ROHS3 Compliant

The TPS2012ADR qualifies as a direct substitute, sharing the same base product number (TPS2012), identical package, and all critical electrical parameters within the specified ranges.

Parameter Comparison

Engineering Selection Recommendations

The TPS2012ADR is the direct substitute for the discontinued TPS2012DRG4. Both components are manufactured by Texas Instruments and share identical mechanical and primary electrical specifications.

Key advantages of the TPS2012ADR:

• Active product status with current manufacturing and distribution support
• Lower on-resistance (33mOhm vs. 75mOhm), resulting in reduced power dissipation
• Enhanced fault protection with UVLO (Under-Voltage Lock-Out) in addition to current limiting and over-temperature protection
• ROHS3 compliant and REACH unaffected, meeting regulatory requirements
• Identical 8-SOIC package footprint for direct PCB compatibility
• Same operating temperature range and voltage specifications

The TPS2012ADR is suitable for direct replacement in applications currently using the TPS2012DRG4 without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the TPS2012ADR be used as a direct replacement for the TPS2012DRG4?

A: Yes. Both parts share identical package geometry (8-SOIC), output configuration (high-side N-Channel), voltage ratings (2.7V ~ 5.5V), and current capacity (1A). The TPS2012ADR is pin-compatible and functionally equivalent for high-side switching applications.

Q: What is the difference in on-resistance between these parts?

A: The TPS2012DRG4 has a typical on-resistance of 75mOhm, while the TPS2012ADR has 33mOhm. The lower on-resistance of the TPS2012ADR reduces power dissipation and heat generation during operation, providing improved thermal performance.

Q: Does the TPS2012ADR include additional protection features?

A: Yes. The TPS2012ADR includes UVLO (Under-Voltage Lock-Out) protection in addition to the current limiting and over-temperature protection found in the TPS2012DRG4. This provides enhanced system reliability under low-voltage conditions.

Q: Are there packaging differences between these parts?

A: The TPS2012DRG4 is supplied in bulk packaging, while the TPS2012ADR is supplied in Tape & Reel (TR) format. Both use the identical 8-SOIC package case. Tape & Reel packaging is standard for automated assembly processes.

Q: What is the product status of each part?

A: The TPS2012DRG4 is discontinued at DiGi Electronics. The TPS2012ADR is an active product with current manufacturing and distribution availability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TPS2012DRG4 and TPS2012ADR are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.
