FSB117HNY-F116 Equivalent & Substitute Parts

Part Overview

The FSB117HNY-F116 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 FSB117HNY-F116 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 equivalent or enhanced performance characteristics suitable for offline converter topologies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FSB117HNY-F116 is determined by the following critical parameters:

Topology Compatibility: All substitute parts operate as offline converter switches using flyback topology, maintaining functional equivalence with the original design.

Electrical Performance: Substitute parts are grouped by voltage breakdown rating (700V or 800V), switching frequency (100kHz), and power handling capability (17W to 31W). Parts with higher power ratings and lower startup voltages provide enhanced performance margins.

Package and Mounting: Substitute parts are available in 7-PDIP and 8-PDIP configurations, both through-hole mounting types compatible with existing PCB layouts.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Product Status: Active substitute parts (NCP1076 series) are preferred over obsolete alternatives for long-term design viability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status): The NCP1076 series (NCP1076AAP100G, NCP1076ABP100G, NCP1076BAP100G, NCP1076BBP100G) are recommended as primary substitutes. These parts maintain active product status with onsemi, ensuring long-term availability and continued manufacturing support. All NCP1076 variants provide 31W power handling, exceeding the FSB117HNY-F116 capability, with lower startup voltage (8.4V) and equivalent 700V breakdown rating.

Secondary Substitute (Obsolete Status): The FSL518APG provides an alternative with 800V breakdown rating and 17W power handling. However, this part shares obsolete status with the original FSB117HNY-F116 and should be considered only when NCP1076 series parts are unavailable.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity with the original component.

Thermal Performance: All substitute parts operate across the -40°C to 125°C junction temperature range, maintaining thermal compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Why is the FSB117HNY-F116 being discontinued?

A: The FSB117HNY-F116 is designated as obsolete by onsemi. Active alternatives from the NCP1076 series provide equivalent or superior performance characteristics and ensure continued manufacturing support.

Q: Can NCP1076 series parts directly replace the FSB117HNY-F116?

A: The NCP1076 series parts operate as offline converter switches with flyback topology, matching the functional classification of the FSB117HNY-F116. All parts maintain ROHS3 compliance and equivalent operating temperature ranges. Pin-to-pin compatibility and circuit-level integration requirements must be verified during design transition.

Q: What is the difference between NCP1076AAP100G, NCP1076ABP100G, NCP1076BAP100G, and NCP1076BBP100G?

A: All four variants share identical electrical specifications: 700V breakdown voltage, 100kHz switching frequency, 31W power rating, 8.4V startup voltage, and -40°C to 125°C operating temperature. Variants differ in internal control feature configurations and output isolation characteristics. Selection depends on specific circuit requirements for isolation and control functionality.

Q: Does the FSL518APG provide equivalent performance to the NCP1076 series?

A: The FSL518APG operates at 800V breakdown voltage and 17W power rating, compared to the NCP1076 series at 700V and 31W. The FSL518APG features a higher startup voltage (16V versus 8.4V). Both share obsolete status. The NCP1076 series is preferred for new designs due to active product status.

Q: Are all substitute parts available in the same package configuration?

A: Substitute parts are available in 7-PDIP and 8-PDIP configurations. Both are through-hole mounting types with 0.300" (7.62mm) pitch. PCB layout compatibility must be verified based on specific package selection.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity with the original FSB117HNY-F116.
