SC2596SETRT Equivalent & Substitute Parts

Part Overview

The SC2596SETRT is a linear LDO (Low Dropout) voltage regulator IC manufactured by Semtech Corporation, designed for DDR voltage regulation applications. This device features a single output with input voltage range of 2.3V to 5.5V and selectable output voltages of 0.9V or 1.25V. The component is housed in an 8-SOIC package with exposed pad and is supplied in Tape & Reel packaging format.

The SC2596SETRT carries a product status designation of "Not For New Designs," indicating that Semtech has discontinued active development and support for this component. This status necessitates identification of functionally equivalent alternatives for ongoing production requirements, maintenance applications, and new design implementations where DDR voltage regulation is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC2596SETRT are identified based on the following critical parameters that determine functional equivalence:

• Package Compatibility: 8-SOIC form factor with matching pin configuration
• Functional Classification: Linear LDO voltage regulator with DDR application support
• Input Voltage Range: Minimum 2.3V input capability with upper range of 5.5V or greater
• Output Configuration: Single output with voltage regulation capability
• Mounting Technology: Surface mount compatibility
• Environmental Rating: Operating temperature range encompassing -40°C to 105°C minimum

The primary substitute identified is the NCP51198PDR2G manufactured by onsemi. This component meets the core functional and package requirements while offering extended operating temperature range and alternative packaging format options.

Parameter Comparison

Engineering Selection Recommendations

The NCP51198PDR2G serves as a functional equivalent to the SC2596SETRT for DDR voltage regulation applications. Both components share identical package geometry (8-SOIC), single-output configuration, and overlapping input voltage specifications. The substitute part demonstrates superior environmental performance with an extended operating temperature range of -40°C to 125°C compared to the main part's -40°C to 105°C specification.

Both components maintain RoHS compliance status, with the substitute meeting ROHS3 requirements. The NCP51198PDR2G carries an "Obsolete" product status designation, indicating that both the original and substitute components are no longer in active production. This status applies to both options and should be considered when evaluating long-term supply chain requirements.

The primary distinction between these components is the moisture sensitivity level: the SC2596SETRT is rated MSL 1 (Unlimited), while the NCP51198PDR2G is rated MSL 3 (168 Hours). This difference may impact storage and handling procedures depending on manufacturing environment conditions.

Frequently Asked Questions (FAQ)

Q: Can the NCP51198PDR2G directly replace the SC2596SETRT in existing designs?

A: The NCP51198PDR2G is functionally equivalent for DDR voltage regulation applications. Both components utilize the 8-SOIC package with identical pin pitch and mounting requirements. Electrical specifications for input voltage range and single-output configuration are compatible. Pin-level verification against specific application schematics is required to confirm direct substitution.

Q: What is the significance of the different moisture sensitivity levels?

A: The SC2596SETRT is rated MSL 1 (Unlimited), meaning it has no moisture sensitivity restrictions during storage. The NCP51198PDR2G is rated MSL 3 (168 Hours), requiring controlled storage conditions and limiting the component to 168 hours of exposure to uncontrolled ambient conditions before soldering. Manufacturing environments with humidity control systems can accommodate MSL 3 components without operational impact.

Q: Why are both the main part and substitute marked as discontinued?

A: Both the SC2596SETRT (Not For New Designs) and NCP51198PDR2G (Obsolete) have been discontinued by their respective manufacturers. This indicates that neither component is recommended for new design implementations. Existing inventory may be available through authorized distributors for maintenance and legacy system support.

Q: Are there differences in output voltage specifications between these parts?

A: The SC2596SETRT specifies output voltage options of 0.9V and 1.25V. The NCP51198PDR2G does not list specific output voltage values in the provided specifications. Application-specific voltage requirements must be verified against the NCP51198PDR2G datasheet to confirm compatibility with intended DDR voltage regulation needs.

Q: What is the operating temperature difference between these components?

A: The SC2596SETRT operates across -40°C to 105°C, while the NCP51198PDR2G extends to -40°C to 125°C. The substitute part provides 20°C additional high-temperature capability, which may be advantageous in thermal-constrained applications or environments with elevated ambient temperatures.
