FSL136HR Equivalent & Substitute Parts

Part Overview

The FSL136HR is an offline switch flyback converter IC manufactured by onsemi, designed for isolated power management applications. This 8-DIP through-hole component operates at 100kHz switching frequency with 26W power capability and integrated fault protection including current limiting, overload, overvoltage, and short circuit protection. The part is Active status and ROHS3 compliant, making it suitable for modern industrial and consumer applications requiring galvanic isolation.

Substitute parts are identified when design requirements allow flexibility in specific electrical parameters while maintaining core functional compatibility within the FPS™ series topology and package footprint.

Parameter Comparison

Engineering Selection Recommendations

FSL136HR (Primary Part): Select when 26W power output at 100kHz switching frequency is required. All three parts maintain Active product status and ROHS3 compliance.

FSL116HR: Suitable for applications requiring lower power output (16W maximum). Maintains identical switching frequency (100kHz) and all protection features. Identical thermal and electrical specifications except power rating.

FSL136MR: Suitable for applications where lower switching frequency (67kHz) is acceptable or preferred. Maintains 26W power output matching the primary part. Identical thermal and electrical specifications except switching frequency.

All three parts share identical package footprint, mounting type, and compliance certifications, enabling direct PCB compatibility within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can FSL116HR replace FSL136HR in all applications? A: FSL116HR is suitable only when maximum power requirement does not exceed 16W. Both parts operate at identical 100kHz switching frequency and share all other electrical and thermal specifications. PCB layout compatibility is maintained due to identical 8-DIP package.

Q: What is the primary difference between FSL136HR and FSL136MR? A: The switching frequency differs: FSL136HR operates at 100kHz while FSL136MR operates at 67kHz. Both deliver 26W power output. Selection depends on application requirements for switching frequency and associated EMI/filtering considerations.

Q: Are all three parts pin-compatible? A: Yes. All three parts use identical 8-DIP (0.300", 7.62mm) through-hole package, ensuring direct PCB compatibility without layout modifications.

Q: Do all substitute parts meet the same compliance standards? A: Yes. FSL136HR, FSL116HR, and FSL136MR are all ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: What determines whether a substitute is acceptable? A: Substitution is valid when the application's power requirement and switching frequency tolerance align with the substitute part's specifications. All other parameters (topology, isolation, voltage ratings, protection features, temperature range) remain identical across all three parts.
