RT9712DGS Equivalent & Substitute Parts

Part Overview

The RT9712DGS is a Power Management IC (PMIC) functioning as a power switch/driver with 1:1 input-to-output ratio and N-channel configuration. Manufactured by Richtek USA Inc., this component is rated for 1.1A maximum output current with 90mOhm typical on-resistance in an 8-SOP package. The RT9712DGS is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT9712DGS are identified based on strict parametric alignment across the following critical criteria:

Parametric Equivalent (RT9712CGS): Shares identical electrical specifications including 1:1 input-to-output ratio, 1.1A maximum output current, 90mOhm on-resistance, N-channel high-side configuration, 2.7V ~ 5.5V load voltage range, and 8-SOIC package. The primary distinction is product status: RT9712CGS is active, whereas RT9712DGS is obsolete. Both are manufactured by Richtek USA Inc. and comply with ROHS3.

Similar Manufacturer Part (TPS2062CDR): Manufactured by Texas Instruments, this part shares the same package type (8-SOIC), switch type (general purpose N-channel), output configuration (high side), on-resistance (90mOhm), and fault protection features. Key differences include a 1:2 input-to-output ratio (versus 1:1), reduced maximum output current (1A versus 1.1A), narrower load voltage range (4.5V ~ 5.5V versus 2.7V ~ 5.5V), and extended operating temperature range (-40°C ~ 125°C junction temperature versus -40°C ~ 85°C ambient temperature). The TPS2062CDR is active and carries MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

RT9712CGS is the direct parametric equivalent for RT9712DGS replacement. Both parts are manufactured by Richtek USA Inc., maintain identical electrical and mechanical specifications, and comply with ROHS3 standards. The RT9712CGS is currently in active production status, ensuring supply chain availability and long-term support. This part is the preferred choice for direct substitution in applications requiring the 1:1 input-to-output ratio and 2.7V ~ 5.5V load voltage range.

TPS2062CDR serves as an alternative for applications where the design specifications permit accommodation of the following parameter variations: 1:2 input-to-output ratio, maximum output current of 1A (versus 1.1A), and minimum load voltage of 4.5V (versus 2.7V). The TPS2062CDR offers extended operating temperature range and superior moisture sensitivity rating (MSL 1). This part is suitable for designs with thermal margin and applications operating within the 4.5V ~ 5.5V load voltage window.

Both substitute parts are ROHS3 compliant and carry REACH Unaffected status, maintaining regulatory alignment with the original RT9712DGS.

Frequently Asked Questions (FAQ)

Q: Can RT9712CGS be used as a direct drop-in replacement for RT9712DGS?

A: Yes. The RT9712CGS is a parametric equivalent with identical electrical specifications, package type, and pin configuration. No circuit modifications are required for substitution.

Q: What are the key differences between RT9712DGS and TPS2062CDR?

A: The primary differences are input-to-output ratio (1:1 versus 1:2), maximum output current (1.1A versus 1A), and load voltage range (2.7V ~ 5.5V versus 4.5V ~ 5.5V). Both share the same package, on-resistance, and fault protection architecture. TPS2062CDR is suitable only if your application operates within the 4.5V ~ 5.5V load voltage range and can tolerate the 1:2 ratio configuration.

Q: Are all three parts pin-compatible?

A: All three parts use the 8-SOIC package with identical physical dimensions (0.154", 3.90mm width). However, pin compatibility depends on circuit topology. RT9712CGS is a direct pin-compatible replacement for RT9712DGS. TPS2062CDR may require circuit evaluation due to the 1:2 input-to-output ratio difference.

Q: What is the moisture sensitivity implication of MSL 3 versus MSL 1?

A: MSL 3 (RT9712DGS and RT9712CGS) requires storage at controlled humidity with a 168-hour floor life after moisture exposure. MSL 1 (TPS2062CDR) has unlimited floor life and is suitable for environments with less stringent moisture control requirements.

Q: Why is RT9712DGS classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured. RT9712CGS provides continued access to equivalent functionality from the same manufacturer with active production support.
