SC417MLTRC Equivalent & Substitute Parts

Part Overview

The SC417MLTRC is a dual-output Power Management IC (PMIC) manufactured by Semtech Corporation, featuring integrated step-down (buck) synchronous and linear (LDO) voltage regulation topologies. This device operates at 1MHz switching frequency and delivers adjustable output at 10A from the buck converter and fixed 5V at 200mA from the linear regulator, supporting input voltage ranges from 3V to 28V. The SC417MLTRC is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitute parts for the SC417MLTRC are identified based on strict parametric equivalence across the following critical criteria:

• Identical dual-output topology: Step-down (buck) synchronous and linear (LDO) regulation
• Matching output specifications: Adjustable 10A buck output and fixed 5V 200mA linear output
• Identical switching frequency: 1MHz operation
• Matching input voltage range: 3V to 28V supply compatibility
• Identical package and pinout: 32-WFQFN Exposed Pad (32-MLPQ 5x5)
• Identical operating temperature range: -40°C to 85°C
• Matching regulatory compliance: RoHS Compliant status
• Same manufacturer: Semtech Corporation

The SC417MLTRT qualifies as a parametric equivalent substitute, differing only in packaging format (Cut Tape versus standard packaging), which does not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SC417MLTRC and SC417MLTRT maintain identical electrical and mechanical specifications, ensuring direct substitutability in circuit design and PCB assembly. Selection between these parts should be based on procurement and inventory requirements:

The SC417MLTRC is suitable for applications requiring standard packaging formats and lower volume orders. The SC417MLTRT, supplied in Cut Tape (CT) format, is optimized for high-volume automated assembly operations where tape-and-reel packaging reduces handling and improves production efficiency.

Both parts carry RoHS Compliant certification and MSL Level 1 (Unlimited) moisture sensitivity rating, confirming suitability for standard manufacturing and storage conditions without special handling requirements. The obsolete product status of both variants necessitates verification of long-term availability through authorized distributors prior to new design commitments.

Frequently Asked Questions (FAQ)

Q: Can SC417MLTRT be used as a direct replacement for SC417MLTRC in existing designs?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including topology, output ratings, switching frequency, input voltage range, package type, and operating temperature range. The only difference is packaging format (Cut Tape versus standard), which does not affect circuit functionality or PCB compatibility.

Q: What is the significance of the packaging format difference between SC417MLTRC and SC417MLTRT?

A: The packaging format difference reflects supply chain and manufacturing optimization. SC417MLTRC uses standard packaging suitable for manual or low-volume automated handling. SC417MLTRT uses Cut Tape (CT) format, which is compatible with high-speed automated pick-and-place equipment and reduces component handling time during assembly. Both formats contain identical die and lead configurations.

Q: Are there any compliance or certification differences between these substitute parts?

A: No. Both SC417MLTRC and SC417MLTRT carry identical RoHS Compliance status and Moisture Sensitivity Level (MSL) ratings. They meet the same regulatory and environmental standards, confirming equivalent suitability for applications requiring these certifications.

Q: Why is the SC417MLTRC classified as obsolete, and what does this mean for part selection?

A: Obsolete status indicates that Semtech Corporation has discontinued active production and support for this product line. For ongoing applications, engineers should confirm availability through authorized distributors and consider long-term supply chain planning. The SC417MLTRT, also obsolete, shares this status and should be evaluated under the same availability constraints.

Q: What are the critical parameters that determine substitutability for the SC417MLTRC?

A: Substitutability is determined by matching: dual-output topology (buck synchronous + linear LDO), output voltage and current ratings (adjustable 10A and 5V 200mA), switching frequency (1MHz), input voltage range (3V to 28V), package type (32-WFQFN Exposed Pad), operating temperature range (-40°C to 85°C), and manufacturer (Semtech Corporation). Any deviation in these parameters disqualifies a part as a direct substitute.
