Key Parameters

Substitute Part Grouping Explanation

Substitution for the PS2501-2G is determined by strict equivalence across the following critical parameters:

• Number of Channels: 2
• Voltage - Isolation: 5300Vrms
• Current Transfer Ratio range: 80% (Min) to 600% (Max) @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 300mV
• Package / Case: 8-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole
• Operating Temperature: -30°C ~ 100°C

The PS2501-2XG meets all these parameters identically and belongs to the same PS2501-2 series, qualifying it as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both PS2501-2G and PS2501-2XG are active production components from Isocom Components 2004 LTD with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between these parts should be based on inventory availability and procurement lead times, as they are functionally interchangeable in all applications requiring dual-channel optoisolation with 5300Vrms isolation voltage and transistor output in 8-DIP through-hole packaging.

Frequently Asked Questions (FAQ)

Q: Can PS2501-2XG be used as a direct replacement for PS2501-2G?

A: Yes. The PS2501-2XG is a parametric equivalent with identical electrical characteristics, isolation voltage, current transfer ratio, output specifications, and 8-DIP package configuration. No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?
