Substitute Part Grouping Explanation

Substitution of the PS2501-1SMT&R is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 1
• Output Type: Transistor
• Current Transfer Ratio range: 80% (Min) to 600% (Max) @ 5mA
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 300mV
• Package / Case: 4-SMD (0.300", 7.62mm)
• Mounting Type: Surface Mount
• Operating Temperature: -30°C ~ 100°C

The PS2501-1XSMT&R meets all these criteria and is classified as a parametric equivalent. Both parts belong to the PS2501-1 series and maintain identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both PS2501-1SMT&R and PS2501-1XSMT&R are active production components manufactured by Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: PS2501-1SMT&R has 45,200 units in stock, while PS2501-1XSMT&R has 3,073 units available.
