MP110GPR Equivalent & Substitute Parts

Part Overview

The MP110GPR is an offline switch flyback converter IC manufactured by Monolithic Power Systems Inc., designed for isolated power management applications. This 8-PDIP package device operates at switching frequencies up to 300kHz with a 900V breakdown voltage rating and integrated fault protection for overload, overvoltage, overcurrent, and thermal conditions.

The MP110GPR carries a "Not For New Designs" product status, indicating it is a legacy component. For new applications or when stock availability becomes critical, equivalent substitute parts with compatible electrical and mechanical specifications are necessary to maintain design continuity and ensure supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP110GPR is determined by the following critical parameters:

• Topology: Both parts must implement flyback converter architecture with isolated output
• Voltage Rating: Substitute must meet or exceed the 900V breakdown voltage requirement
• Supply Voltage Range: Substitute operating range must encompass or exceed 9V ~ 20V
• Fault Protection: Substitute must include equivalent protection mechanisms (overload, overvoltage, overcurrent, thermal)
• Package Compatibility: Through-hole DIP package with compatible pinout and lead count
• Operating Temperature: Must support -40°C ~ 125°C range
• Compliance: RoHS3 compliance and REACH unaffected status required

The FSL4110LRN from onsemi meets these substitution criteria as an active, production-qualified offline flyback switch with compatible electrical specifications and through-hole DIP packaging.

Engineering Selection Recommendations

The FSL4110LRN is qualified as a direct substitute for the MP110GPR based on the following factors:

• Product Status: FSL4110LRN is an active production component, ensuring long-term availability and supply chain stability compared to the MP110GPR's legacy status
• Electrical Compatibility: The FSL4110LRN exceeds the MP110GPR's voltage specifications (1000V vs. 900V breakdown) and provides a wider supply voltage operating range (8V ~ 27V vs. 9V ~ 20V), ensuring functional compatibility in existing designs
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements
• Package Compatibility: Standard 8-DIP through-hole package with identical footprint dimensions enables direct PCB substitution without layout modifications
• Thermal Performance: Identical operating temperature range (-40°C ~ 125°C) ensures thermal design compatibility

Selection of FSL4110LRN is appropriate for new designs and as a replacement strategy for MP110GPR applications requiring continued production support.

Frequently Asked Questions (FAQ)

Q: Can FSL4110LRN be used as a direct replacement for MP110GPR on existing PCBs?

A: Yes. Both components use the standard 8-DIP (0.300", 7.62mm) through-hole package with compatible pinout and lead spacing. No PCB layout modifications are required for substitution.

Q: What are the key electrical differences between these parts?

A: FSL4110LRN provides higher voltage ratings (1000V vs. 900V breakdown) and a wider supply voltage range (8V ~ 27V vs. 9V ~ 20V). Both maintain identical operating temperature ranges and equivalent fault protection mechanisms. These differences favor the FSL4110LRN for design robustness.

Q: Are there switching frequency differences that affect circuit design?

A: Yes. MP110GPR operates at up to 300kHz, while FSL4110LRN operates at 50kHz. This difference requires transformer and filter component recalculation. Designs optimized for the MP110GPR's higher frequency may require component value adjustments when migrating to FSL4110LRN.

Q: Do both parts meet current compliance standards?

A: Yes. Both MP110GPR and FSL4110LRN are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Why is MP110GPR marked "Not For New Designs"?

A: This designation indicates the component is in legacy status and no longer recommended for new product development. FSL4110LRN, as an active production component, is the appropriate choice for new applications.

Q: What is the moisture sensitivity difference between these parts?

A: MP110GPR has MSL 1 (unlimited moisture sensitivity protection), while FSL4110LRN is not applicable for MSL rating. Standard through-hole component handling practices apply to both parts.
