FSB6627HN Equivalent & Substitute Parts

Part Overview

The FSB6627HN is an offline switch integrated circuit manufactured by onsemi, classified as a Power Management (PMIC) component. This device functions as an offline converter switch for power supply applications. The FSB6627HN is designated as obsolete, necessitating identification of functionally equivalent substitute components for new designs and ongoing production requirements. Active alternative parts from the onsemi NCP1076 and FSL518 series provide direct functional replacement with enhanced specifications and current product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FSB6627HN is determined by the following critical parameters: topology classification (offline converter switch), manufacturer alignment (onsemi), functional category (Power Management PMIC), and regulatory compliance (ROHS3 and REACH status). All identified substitute parts maintain these core attributes while providing active product status and enhanced electrical specifications.

The substitute parts are grouped into two functional categories:

Flyback Topology Offline Switches (Primary Substitutes): NCP1076AAP100G, NCP1076ABP100G, NCP1076BAP100G, and NCP1076BBP100G represent the NCP1076 series with isolated output configuration, 700V breakdown voltage, and 31W power rating. These components are designated as active products with current manufacturing status.

Alternative Flyback Topology: FSL518APG represents the FSL518 series with either output isolation configuration, 800V breakdown voltage, and 17W power rating. This component is designated as obsolete but remains available in inventory.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs): The NCP1076 series components (NCP1076AAP100G, NCP1076ABP100G, NCP1076BAP100G, NCP1076BBP100G) are designated as active products with current manufacturing status. These parts maintain full ROHS3 compliance and REACH unaffected status. Selection between 7-PDIP (NCP1076AAP100G, NCP1076ABP100G) and 8-PDIP (NCP1076BAP100G, NCP1076BBP100G) variants is determined by printed circuit board layout requirements and lead configuration specifications.

Alternative Substitute (Inventory Availability): The FSL518APG component provides functional offline switch capability with higher voltage breakdown rating (800V versus 700V) but lower power rating (17W versus 31W). This part is designated as obsolete and should be considered only when NCP1076 series availability is constrained.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the original FSB6627HN specification. Through-hole mounting type is standard across all substitute options, supporting direct board-level replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can NCP1076AAP100G and NCP1076ABP100G be used interchangeably with FSB6627HN?

A: Both NCP1076AAP100G and NCP1076ABP100G function as direct substitutes for the FSB6627HN. Both components are 7-PDIP configuration, active products, and provide identical electrical specifications (700V breakdown, 31W power, 100kHz switching frequency). Selection between these variants is determined by specific control feature requirements and circuit design parameters not specified in the base FSB6627HN documentation.

Q: What is the difference between 7-PDIP and 8-PDIP package configurations?

A: The NCP1076 series is available in both 7-PDIP (NCP1076AAP100G, NCP1076ABP100G) and 8-PDIP (NCP1076BAP100G, NCP1076BBP100G) configurations. Both maintain identical electrical specifications and through-hole mounting. Package selection is determined by printed circuit board layout, lead count requirements, and specific application pinout compatibility.

Q: Why is FSL518APG listed as an alternative if it is also obsolete?

A: FSL518APG is identified as a functional substitute based on offline switch topology and onsemi manufacturer alignment. However, this component is designated as obsolete. The NCP1076 series represents the preferred substitution path due to active product status and enhanced power rating (31W versus 17W).

Q: Are all substitute parts ROHS3 compliant?

A: All identified substitute parts (NCP1076AAP100G, NCP1076ABP100G, NCP1076BAP100G, NCP1076BBP100G, and FSL518APG) are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original FSB6627HN specification.

Q: What is the voltage breakdown difference between NCP1076 and FSL518 series?

A: The NCP1076 series provides 700V breakdown voltage, while FSL518APG provides 800V breakdown voltage. Selection between these options is determined by application voltage stress requirements and circuit design specifications.

Q: Can FSB6627HN designs be directly migrated to NCP1076 components without circuit modification?

A: Direct migration feasibility is determined by specific circuit design parameters, pinout compatibility, and control feature alignment. The provided parameter data confirms functional category alignment and regulatory compliance but does not specify detailed pinout or control feature compatibility. Circuit-level design review is required to confirm direct substitution viability.
