Parameter Comparison

Engineering Selection Recommendations

Both PS2501-1LSM and PS2501-1XLSM are Active product status components with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can PS2501-1XLSM be used as a direct replacement for PS2501-1LSM?

A: Yes. The PS2501-1XLSM is a parametric equivalent with identical isolation voltage (5300Vrms), current transfer ratio (200-400% @ 5mA), output characteristics (80V max, 50mA per channel), and package specifications (4-SMD, 0.300" / 7.62mm). Both components share the same operating temperature range (-30°C ~ 100°C) and compliance certifications.

Q: Are there any differences in package or mounting between these parts?

A: No. Both PS2501-1LSM and PS2501-1XLSM use identical 4-SMD surface mount packaging with 0.300" (7.62mm) dimensions. PCB layout and reflow profiles remain unchanged.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is rated at MSL 1 (Unlimited) for both parts.

Q: What determines substitution eligibility for PS2501-1 series optoisolators?

A: Substitution is valid when the following parameters match: isolation voltage (5300Vrms), channel count (1), output type (Transistor), current transfer ratio range (200-400% @ 5mA), maximum output voltage (80V), output current (50mA), saturation voltage (300mV max), operating temperature (-30°C ~ 100°C), and package type (4-SMD surface mount).
