Parameter Comparison

Engineering Selection Recommendations

All three parts—TLP620SMT&R, ISP620-1XSMT&R, and TLP620XGBSMT&R—are manufactured by Isocom Components 2004 LTD and maintain active product status. Each part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between these parts may be based on inventory availability, as current stock levels differ: TLP620SMT&R (45,300 pcs), ISP620-1XSMT&R (2,011 pcs), and TLP620XGBSMT&R (1,625 pcs). All parts are classified under ECCN EAR99 and HTSUS 8541.49.8000.

Frequently Asked Questions (FAQ)

Q: Can ISP620-1XSMT&R be used as a direct replacement for TLP620SMT&R?

A: Yes. Both parts share identical electrical specifications including isolation voltage (5300Vrms), current transfer ratio range (50–600% @ 5mA), output characteristics (55V max, 50mA per channel), and operating temperature range (-30°C to 100°C). Both use 4-SMD Gull Wing packaging and are surface-mount components.

Q: What is the difference between TLP620XGBSMT&R and TLP620SMT&R?

A: The parts are electrically and mechanically equivalent. Both belong to the TLP620 series, share the same isolation rating, current transfer ratio specifications, and package configuration. Differences exist only in part number designation and series classification.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use identical mounting type (surface mount) and package configuration (4-SMD, Gull Wing), ensuring compatibility with the same PCB footprint and assembly process.

Q: Do these parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Q: Which part should be selected based on availability?

A: Selection should be based on supply chain requirements and inventory levels. TLP620SMT&R has the highest stock (45,300 pcs), followed by ISP620-1XSMT&R (2,011 pcs) and TLP620XGBSMT&R (1,625 pcs). All are functionally interchangeable.
