RT9712BGS Equivalent & Substitute Parts

Part Overview

The RT9712BGS is a Power Management Integrated Circuit (PMIC) manufactured by Richtek USA Inc., functioning as an N-Channel power switch driver with 1:1 input-to-output ratio and 1.5A maximum output current. This component is classified as Obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part operates across a load voltage range of 2.7V to 5.5V with integrated fault protection including current limiting, over-temperature monitoring, reverse current protection, and under-voltage lockout (UVLO).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT9712BGS are identified based on strict parametric alignment across the following critical criteria:

Primary Equivalence Criteria:

• Switch Type: General Purpose N-Channel
• Output Configuration: High Side
• Number of Outputs: 2
• Maximum Output Current: 1.5A
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• Interface: On/Off control
• Input Type: Non-Inverting
• Mounting Type: Surface Mount
• RoHS3 Compliance

Substitution Categories:

Parametric Equivalent: RT9712AGS maintains identical electrical specifications, output configuration, current rating, and fault protection architecture. The primary distinction is product status (Active vs. Obsolete) and increased inventory availability. This part is a direct functional replacement with no design modifications required.

Similar Substitute: TPS2060CDGN provides functional substitution with allowable parameter variations. While maintaining identical output current (1.5A), switch type, and core fault protection features, this part differs in input-to-output ratio (1:2 vs. 1:1), load voltage range (4.5V ~ 5.5V vs. 2.7V ~ 5.5V), on-resistance (70mOhm vs. 90mOhm), operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C), and package format (8-HVSSOP vs. 8-SOIC). Additional features include load discharge capability and superior moisture sensitivity rating (MSL 1 vs. MSL 3).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Modification): RT9712AGS is the recommended substitute when component obsolescence requires immediate replacement. This part maintains identical electrical specifications, package footprint, and thermal characteristics as the RT9712BGS. Both parts are ROHS3 compliant and share the same base product number (RT9712). The RT9712AGS is currently in Active product status with substantial inventory availability (20,400 pcs), ensuring procurement continuity.

For Design Flexibility Applications: TPS2060CDGN serves as a functional alternative when design parameters permit accommodation of specification variations. This substitution is applicable in systems where the load voltage range can be constrained to 4.5V ~ 5.5V (versus the original 2.7V ~ 5.5V), where the 1:2 input-to-output ratio aligns with circuit topology requirements, and where the reduced on-resistance (70mOhm) and extended operating temperature range (-40°C ~ 125°C) provide performance advantages. The TPS2060CDGN offers superior moisture sensitivity characteristics (MSL 1) and includes load discharge functionality. Package footprint differences (8-HVSSOP versus 8-SOIC) require PCB layout modification.

Both substitute options maintain ROHS3 compliance and core fault protection architecture (current limiting, over-temperature, reverse current, UVLO), ensuring regulatory and functional compatibility within their respective parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can RT9712AGS be used as a direct drop-in replacement for RT9712BGS? A: Yes. The RT9712AGS is a parametric equivalent with identical electrical specifications, package dimensions (8-SOIC), and mounting type. No circuit design modifications are required. Both parts share the same base product number and maintain equivalent fault protection features.

Q: What are the key differences between RT9712BGS and TPS2060CDGN? A: The primary differences are: (1) Input-to-output ratio (1:1 vs. 1:2), (2) Load voltage range (2.7V ~ 5.5V vs. 4.5V ~ 5.5V), (3) On-resistance (90mOhm vs. 70mOhm), (4) Operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C), (5) Package format (8-SOIC vs. 8-HVSSOP), and (6) Moisture sensitivity rating (MSL 3 vs. MSL 1). The TPS2060CDGN includes load discharge functionality not present in the RT9712BGS.

Q: Does TPS2060CDGN require PCB layout changes? A: Yes. The TPS2060CDGN uses an 8-HVSSOP package (0.118" width) compared to the 8-SOIC package (0.154" width) of the RT9712BGS. PCB footprint modification is necessary. The TPS2060CDGN includes an exposed pad, which may require additional thermal management considerations in layout design.

Q: Are all substitute parts ROHS3 compliant? A: Yes. Both RT9712AGS and TPS2060CDGN are ROHS3 compliant, maintaining regulatory alignment with the original RT9712BGS.

Q: Which substitute should be selected for low-voltage applications below 4.5V? A: RT9712AGS is the appropriate selection for applications requiring load voltages below 4.5V, as it maintains the original 2.7V ~ 5.5V load voltage range. TPS2060CDGN is limited to 4.5V ~ 5.5V and is not suitable for lower voltage operation.

Q: What is the impact of the different input-to-output ratios (1:1 vs. 1:2)? A: The input-to-output ratio determines the number of independent switch channels controlled by input signals. RT9712BGS and RT9712AGS use 1:1 ratio (one input controls one output), while TPS2060CDGN uses 1:2 ratio (one input controls two outputs). Circuit topology and control logic must align with the selected ratio.
