Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC724CSTRT is determined by strict equivalence across the following critical parameters:

• Functional Architecture: 1:1 N-Channel power switch configuration with single output
• Electrical Performance: 2A maximum output current, 24mOhm typical on-resistance, 1.1V to 3.6V load voltage range
• Interface Type: On/Off control logic
• Package Compatibility: 4-CSP (0.76x0.76) form factor with 4-WFBGA/CSPBGA case designation
• Environmental Compliance: RoHS Compliant status, MSL Level 1, operating temperature range -40°C to 85°C
• Mounting Standard: Surface Mount technology

The SC725CSTRT qualifies as a manufacturer-recommended substitute, maintaining identical electrical specifications and package geometry while offering improved feature set and current production status.

Parameter Comparison

Engineering Selection Recommendations

The SC725CSTRT is the manufacturer-designated substitute for the obsolete SC724CSTRT. Both components maintain identical electrical and mechanical specifications across all critical parameters including output current rating, on-resistance, voltage range, package geometry, and thermal operating range.

Selection between these parts is determined by:

1. Supply Availability: SC725CSTRT offers significantly higher inventory availability (9035 Pcs vs. 630 Pcs), providing superior supply chain reliability.

2. Compliance Status: Both components maintain RoHS Compliance and MSL Level 1 certification, ensuring regulatory and environmental compatibility.

3. Feature Enhancement: SC725CSTRT incorporates Load Discharge functionality in addition to Slew Rate Control, providing enhanced circuit protection without compromising electrical equivalence.

4. Packaging Format: SC725CSTRT is supplied in Tape & Reel format, standard for automated assembly processes, whereas SC724CSTRT availability is limited to bulk packaging.

5. Product Lifecycle: Both components carry legacy product status (Obsolete vs. Not For New Designs), indicating neither is recommended for new design initiation. For existing production requiring component replacement, SC725CSTRT is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can SC725CSTRT directly replace SC724CSTRT in existing circuit designs?

A: Yes. The SC725CSTRT maintains identical electrical specifications (2A output current, 24mOhm on-resistance, 1.1V-3.6V load voltage), identical package geometry (4-CSP 0.76x0.76), and identical pin configuration. No circuit modifications are required for direct substitution.

Q: What is the difference between the two parts?

A: The primary differences are: (1) SC725CSTRT includes Load Discharge feature in addition to Slew Rate Control; (2) SC725CSTRT is supplied in Tape & Reel packaging versus bulk; (3) SC725CSTRT has significantly higher current inventory availability. Electrical and mechanical specifications are identical.

Q: Are both parts suitable for new designs?

A: No. Both SC724CSTRT (Obsolete) and SC725CSTRT (Not For New Designs) carry legacy product status. For new design applications, consultation with Semtech Corporation is required to identify current-generation power switch alternatives meeting equivalent functional requirements.

Q: What is the significance of the 4-CSP package designation?

A: The 4-CSP (Chip Scale Package) 0.76x0.76mm is a miniaturized surface-mount package. Both parts use identical 4-WFBGA/CSPBGA case designation, ensuring mechanical and electrical compatibility in PCB layouts designed for either component.

Q: Does SC725CSTRT's Load Discharge feature affect circuit compatibility?

A: Load Discharge is an additional protective feature that does not alter the core switching functionality or electrical interface. Circuits designed for SC724CSTRT will operate identically with SC725CSTRT; the additional feature provides enhanced circuit protection without requiring design changes.

Q: What is MSL Level 1 and why is it important?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life without moisture-control packaging requirements. Both parts carry this classification, eliminating special storage or handling procedures during component procurement and assembly.

Q: Are both parts RoHS Compliant?

A: Yes. Both SC724CSTRT and SC725CSTRT are RoHS Compliant, meeting European Union Restriction of Hazardous Substances regulations. Both are suitable for applications requiring RoHS certification.
