Critical Matching Parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor
• Current Transfer Ratio: 100% - 300% @ 5mA
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Rise / Fall Time: 3µs, 5µs
• Vce Saturation (Max): 300mV
• Operating Temperature Range: -55°C ~ 100°C
• Package / Case: 4-SMD, Gull Wing
• Mounting Type: Surface Mount

Parts meeting all these parameters are classified as direct substitutes and maintain functional and mechanical compatibility with the original PS2501L-1-E3-D-A design.

Parameter Comparison

Engineering Selection Recommendations

The PS2501L-1-F3-D-A manufactured by Renesas Electronics Corporation is a direct substitute for the obsolete PS2501L-1-E3-D-A. Both components share identical electrical specifications, mechanical packaging, and thermal operating ranges.

Product Status Consideration: The PS2501L-1-E3-D-A is obsolete, while the PS2501L-1-F3-D-A is active. Selection of the active substitute part ensures continued availability and long-term supply chain support.

Compliance Status: The PS2501L-1-F3-D-A carries RoHS3 compliance certification and is REACH unaffected, providing enhanced regulatory alignment compared to the original part. Both components maintain EAR99 export classification and identical HTSUS coding.

Functional Compatibility: All critical electrical parameters—isolation voltage, current transfer ratio, output voltage and current ratings, switching times, and saturation characteristics—are identical between the main part and substitute. The 4-SMD gull wing package and surface mount configuration ensure mechanical compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the PS2501L-1-F3-D-A be used as a direct replacement for PS2501L-1-E3-D-A in existing designs?
