FSL136MRG Equivalent & Substitute Parts

Part Overview

The FSL136MRG is an offline switch flyback converter IC manufactured by onsemi, designed for isolated power management applications. This component operates at 67kHz switching frequency with 26W power capacity and integrated fault protection including current limiting, overload, overvoltage, and short circuit protection. The FSL136MRG is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The FSL136MRG has one direct equivalent substitute: FSL136MR. This substitution is valid based on the following matching parameters:

• Identical manufacturer part number base (FSL136)
• Same topology (Flyback)
• Identical output isolation (Isolated)
• Matching voltage breakdown rating (650V)
• Identical supply voltage range (8V ~ 26V)
• Identical startup voltage (12V)
• Matching switching frequency (67kHz)
• Identical power rating (26W)
• Matching duty cycle (77%)
• Identical fault protection features (Current Limiting, Over Load, Over Temperature, Over Voltage, Short Circuit)
• Matching operating temperature range (-40°C ~ 105°C)
• Identical package type (8-DIP, 0.300", 7.62mm)
• Identical mounting type (Through Hole)
• Same series designation (FPS™)

The primary difference is product status: FSL136MRG is obsolete while FSL136MR is active, and packaging format (FSL136MRG has unspecified packaging versus FSL136MR in Tube packaging).

Parameter Comparison

Engineering Selection Recommendations

FSL136MR is the direct active equivalent for FSL136MRG. The substitute part maintains full electrical and mechanical compatibility across all critical parameters. FSL136MR is currently in active production status with 26,300 units in stock, compared to the obsolete FSL136MRG with 903 units remaining. FSL136MR carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs. Both parts share identical FPS™ series designation, confirming design continuity within onsemi's offline switch product line.

Frequently Asked Questions (FAQ)

Q: Can FSL136MR directly replace FSL136MRG in existing designs?

A: Yes. FSL136MR is electrically and mechanically identical to FSL136MRG across all specified parameters including topology, voltage ratings, switching frequency, power capacity, fault protection, operating temperature range, and 8-DIP package configuration.

Q: What is the primary reason to transition from FSL136MRG to FSL136MR?

A: FSL136MRG is classified as obsolete product status. FSL136MR is the active equivalent, ensuring long-term supply availability and production support from onsemi.

Q: Are there packaging differences between these parts?

A: FSL136MRG packaging is unspecified in available documentation. FSL136MR is supplied in Tube packaging. Both use identical 8-DIP (0.300", 7.62mm) physical package format suitable for through-hole mounting.

Q: Does FSL136MR meet current regulatory requirements?

A: FSL136MR is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Are the electrical characteristics identical between FSL136MRG and FSL136MR?

A: Yes. Both parts operate at 67kHz switching frequency, support 8V to 26V supply voltage, feature 650V breakdown voltage, deliver 26W power capacity, maintain 77% duty cycle, and include identical fault protection (current limiting, overload, overvoltage, overheat, and short circuit protection).
