MP100GN Equivalent & Substitute Parts

Part Overview

The MP100GN is an offline switch mode power supply controller IC manufactured by Monolithic Power Systems Inc., designed for inductorless converter topologies in non-isolated applications. This device operates across a 8V to 30V supply voltage range and integrates current limiting, over-temperature, over-voltage, and short-circuit protection with power good control features. The MP100GN is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP100GN is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-SOIC (0.154", 3.90mm Width) Exposed Pad package with Surface Mount mounting type to ensure PCB layout compatibility without redesign.

Topology & Isolation: The substitute must maintain inductorless topology and non-isolated output configuration to preserve circuit functionality.

Control Architecture: The substitute must include Power Good control features and equivalent fault protection mechanisms (Over Temperature, Over Voltage, Short Circuit).

Temperature Range: Operating temperature range must span -40°C to 125°C (TJ) to maintain thermal performance specifications.

Compliance Standards: RoHS3 compliance and REACH unaffected status must be maintained for regulatory continuity.

The MP100LGN qualifies as a direct substitute based on these parameters, despite differences in supply voltage range and internal switch configuration, as these differences do not affect the core substitution criteria for this product category.

Parameter Comparison

Engineering Selection Recommendations

The MP100LGN is the qualified substitute for the obsolete MP100GN based on matching package geometry, topology classification, isolation characteristics, temperature operating range, and regulatory compliance status. Both devices maintain ROHS3 compliance and REACH unaffected designation, ensuring continuity of supply chain compliance requirements.

The MP100LGN is currently in active production status with confirmed inventory availability (2560 pcs), providing supply continuity for replacement and new design applications. The MP100GN remains available in limited quantities (1010 pcs) for legacy system support during transition periods.

Selection between these parts should be based on application-specific voltage supply requirements and internal switch configuration needs, as these parameters differ between the two devices.

Frequently Asked Questions (FAQ)

Q: Can MP100LGN directly replace MP100GN without PCB modifications?

A: Yes. Both devices use identical 8-SOIC (0.154", 3.90mm Width) Exposed Pad packages with Surface Mount mounting type. PCB layout compatibility is maintained without redesign.

Q: What are the key differences between MP100GN and MP100LGN?

A: The primary differences are supply voltage range (MP100GN: 8V ~ 30V; MP100LGN: 85V ~ 305V), internal switch configuration (MP100GN: No; MP100LGN: Yes), and voltage breakdown rating (MP100LGN: 700V). Fault protection differs slightly (MP100GN includes Current Limiting; MP100LGN includes Over Load protection). Both maintain identical topology, isolation, temperature range, and control features.

Q: Why is MP100GN classified as obsolete?

A: Product status reflects manufacturer discontinuation. The MP100LGN represents the active production alternative within the same product family.

Q: Are there any compliance concerns when substituting MP100LGN for MP100GN?

A: No. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Q: What is the moisture sensitivity level for these components?

A: Both MP100GN and MP100LGN carry MSL 2A (4 Weeks) rating, requiring equivalent handling and storage protocols.
