Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HR1001LGS are identified based on strict parametric equivalence across the following critical criteria:

• Identical package and pinout: 16-SOIC (0.154", 3.90mm Width)
• Matching electrical specifications: Input voltage range (-0.3V ~ 6V), supply voltage range (13V ~ 15.5V), and supply current (3 mA)
• Identical operating temperature range: -40°C ~ 125°C (TJ)
• Same mounting technology: Surface Mount
• Equivalent compliance certifications: RoHS3 Compliant, REACH Unaffected
• Identical moisture sensitivity level: MSL 2 (1 Year)
• Same functional application scope: Flyback, Forward Converters, LLC

The HR1001CGS meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both HR1001LGS and HR1001CGS are active products from Monolithic Power Systems Inc. with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability and supply chain considerations rather than functional differences. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial power management applications. The identical MSL rating of 2 (1 Year) requires equivalent moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can HR1001CGS replace HR1001LGS in existing designs? A: Yes. The HR1001CGS is a parametric equivalent with identical electrical specifications, package geometry, and compliance certifications. Direct substitution is supported without circuit modification.

Q: Are there differences in pinout between these parts? A: No. Both parts use the 16-SOIC package with identical pin configuration and spacing (0.154", 3.90mm Width).

Q: Do these parts have the same operating temperature range? A: Yes. Both parts operate across -40°C to 125°C junction temperature, supporting identical thermal design requirements.

Q: What is the significance of the MSL rating for these parts? A: Both parts carry MSL 2 (1 Year), indicating they require storage below 30°C and 85% relative humidity. Moisture exposure beyond one year requires baking before reflow soldering.

Q: Are both parts RoHS3 compliant? A: Yes. Both HR1001LGS and HR1001CGS are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What applications are these controllers suitable for? A: Both parts are designed for Flyback, Forward Converter, and LLC topology power supplies, with input voltage range of -0.3V to 6V and supply voltage range of 13V to 15.5V.
