Procurement Notes
Verify the specific suffix 'XSMT&R' against official Isocom documentation to confirm tape-and-reel packaging and exact lead spread specifications. Ensure compatibility with automated pick-and-place equipment due to the surface-mount format. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or material declarations prior to final procurement approval.
Selection Notes
Select this component when space constraints require a surface-mount solution for optocouplers. It is suitable for applications needing high isolation voltage and reliable digital signal transmission. Consider the current transfer ratio requirements and operating temperature range (-30°C to 100°C) to ensure performance stability in the target environment compared to through-hole alternatives.
Part Context
This part belongs to the PS2501 series of high-density mounting phototransistor optically coupled isolators. The series includes variants with different channel counts and package types, such as DIP and surface-mount options. Isocom Components positions these devices as replacements for standard industry types, offering custom electrical selections to meet specific circuit design requirements while maintaining global manufacturing standards.
Replacement Considerations
Direct substitutes include PS2501-1SM (standard surface mount) and PS2501-1SMT&R (tape and reel). Verify pinout compatibility and isolation voltage ratings when replacing with equivalents from other manufacturers like Renesas or NEC.
