HR1001GS-Z Equivalent & Substitute Parts

Part Overview

The HR1001GS-Z is an Enhanced LLC Controller manufactured by Monolithic Power Systems Inc., 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 input voltage range of -0.3V to 6V and supply voltage of 13V to 15.5V.

The HR1001GS-Z carries a "Not For New Designs" product status, indicating it is obsolete or in end-of-life phase. Identifying equivalent substitute parts with active product status is essential for ongoing production, maintenance, and new design implementations where this controller functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HR1001GS-Z are determined by strict parametric equivalence across the following critical parameters:

• Base Product Number: HR1001
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Voltage - Input: -0.3V ~ 6V
• Voltage - Supply: 13V ~ 15.5V
• Current - Supply: 3 mA
• Operating Temperature: -40°C ~ 125°C (TJ)
• Applications: Flyback, Forward Converters, LLC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

All identified substitute parts maintain identical electrical specifications and mechanical compatibility. Variations exist only in packaging format (Tape & Reel, Cut Tape & Digi-Reel®) and product status (Active vs. Not For New Designs).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using HR1001GS-Z, the following substitutes are available based on product status and compliance certifications:

HR1001LGS-Z is the primary substitute for new designs and ongoing production. This part maintains Active product status, identical electrical and mechanical specifications, and is available in Tape & Reel packaging matching the original HR1001GS-Z format. Inventory availability is highest among all substitutes at 42400 pieces.

HR1001BGS-Z provides an alternative with Active product status and equivalent parametric specifications. This part is packaged in Cut Tape & Digi-Reel® format, suitable for applications where alternative packaging is acceptable. Inventory is available at 22690 pieces.

HR1001CGS-Z is available with Active product status and identical electrical specifications. Packaging format is not specified in available documentation. Inventory availability is 24100 pieces.

All three substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL rating of 2 (1 Year), ensuring regulatory and environmental compatibility with the original HR1001GS-Z.

Frequently Asked Questions (FAQ)

Q: Can HR1001LGS-Z directly replace HR1001GS-Z in existing designs?

A: Yes. HR1001LGS-Z is parametrically equivalent to HR1001GS-Z across all critical electrical and mechanical parameters: input voltage range (-0.3V ~ 6V), supply voltage (13V ~ 15.5V), supply current (3 mA), operating temperature (-40°C ~ 125°C), and 16-SOIC package configuration. Both are available in Tape & Reel packaging.

Q: What is the difference between HR1001BGS-Z and HR1001LGS-Z?

A: The primary difference is packaging format. HR1001LGS-Z is supplied in Tape & Reel (TR) format, while HR1001BGS-Z is supplied in Cut Tape (CT) & Digi-Reel® format. All electrical specifications and the 16-SOIC package type are identical. Selection depends on assembly line requirements and tape format compatibility.

Q: Why is HR1001GS-Z marked "Not For New Designs"?

A: This status indicates the part is in end-of-life phase. Monolithic Power Systems Inc. recommends using active alternatives (HR1001LGS-Z, HR1001BGS-Z, or HR1001CGS-Z) for new product development and ongoing production to ensure long-term supply availability and manufacturer support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. HR1001LGS-Z, HR1001BGS-Z, and HR1001CGS-Z are all ROHS3 compliant with REACH Unaffected status, matching the compliance profile of HR1001GS-Z.

Q: Which substitute has the highest inventory availability?

A: HR1001LGS-Z has the highest inventory at 42400 pieces, followed by HR1001CGS-Z at 24100 pieces and HR1001BGS-Z at 22690 pieces.

Q: Can I use HR1001CGS-Z if packaging format is not specified?

A: HR1001CGS-Z is parametrically equivalent and carries Active product status. However, the unspecified packaging format should be confirmed with the supplier before design implementation to ensure compatibility with assembly equipment and procurement workflows.
