HR1001LGS-Z Equivalent & Substitute Parts

Part Overview

The HR1001LGS-Z is an Enhanced LLC Controller manufactured by Monolithic Power Systems, designed for power supply applications including Flyback, Forward Converters, and LLC topologies. This 16-SOIC surface mount integrated circuit operates as a Power Supply Controller with active product status and full RoHS3 compliance. Substitute parts are identified to provide design flexibility, inventory alternatives, and supply chain continuity while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HR1001LGS-Z are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria are:

• Identical voltage input range: -0.3V ~ 6V
• Identical supply voltage range: 13V ~ 15.5V
• Identical supply current: 3 mA
• Identical operating temperature range: -40°C ~ 125°C (TJ)
• Identical package type: 16-SOIC (0.154", 3.90mm Width)
• Identical mounting type: Surface Mount
• Identical base product number: HR1001
• Identical applications: Flyback, Forward Converters, LLC
• Identical RoHS3 compliance and MSL rating
• Active product status from the same manufacturer

The HR1001BGS-Z meets all these criteria and qualifies as a parametric equivalent. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both HR1001LGS-Z and HR1001BGS-Z are active products from Monolithic Power Systems with identical electrical specifications and RoHS3 compliance. Selection between these parts should be based on:

• Packaging requirements: HR1001LGS-Z is supplied in Tape & Reel format; HR1001BGS-Z is supplied in Cut Tape and Digi-Reel® format
• Inventory availability and lead time considerations
• Supply chain logistics and handling procedures for the required packaging format
• Cost implications associated with packaging and distribution methods

Both parts maintain identical compliance certifications (RoHS3, REACH Unaffected, EAR99) and moisture sensitivity levels, ensuring equivalent performance in power supply controller applications.

Frequently Asked Questions (FAQ)

Q: Can HR1001BGS-Z be used as a direct replacement for HR1001LGS-Z?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, operating ranges, and package dimensions. The only difference is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), which does not affect circuit performance or PCB assembly compatibility.

Q: Are there any differences in the 16-SOIC package between these parts?

A: No. Both parts use the identical 16-SOIC package with 0.154" width and 3.90mm dimensions. Pin configuration, spacing, and mechanical compatibility are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both HR1001LGS-Z and HR1001BGS-Z are RoHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity levels are identical at MSL 2 (1 Year).

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) provides continuous reel packaging for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® provide flexible packaging options for lower volumes or mixed component orders. The electrical and mechanical properties of the component remain unchanged.

Q: Are both parts suitable for Flyback, Forward Converter, and LLC applications?

A: Yes. Both parts are specified for identical applications: Flyback, Forward Converters, and LLC topologies, with matching voltage input (-0.3V ~ 6V), supply voltage (13V ~ 15.5V), and operating temperature ranges (-40°C ~ 125°C).
