Engineering Selection Recommendations

All three parts—TLP620-2G, TLP620-2XG, and ISP620-2XG—are active production components from Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

Compliance Status: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level), indicating equivalent environmental and regulatory compliance.

Availability: Current inventory levels are TLP620-2G (822 units), TLP620-2XG (1008 units), and ISP620-2XG (1161 units). Part selection may be driven by stock availability and lead time requirements.

Direct Substitution: Any of these parts can be substituted for the others without circuit modification, PCB redesign, or performance impact, provided the 8-DIP through-hole package footprint is maintained on the printed circuit board.

Frequently Asked Questions (FAQ)

Q: Can TLP620-2XG or ISP620-2XG be used as direct replacements for TLP620-2G?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, isolation voltage, current transfer ratios, switching times, output voltage/current ratings, operating temperature range, and 8-DIP package dimensions. No circuit redesign is required.

Q: Are there any differences in isolation voltage or switching performance between these parts?

A: No. All three parts provide 5300Vrms isolation voltage, identical current transfer ratios (50% to 600% @ 5mA), and matching rise/fall times (4µs, 3µs).

Q: Do these parts have the same package footprint?

A: Yes. All parts use the 8-DIP (0.400", 10.16mm) through-hole package with identical pin spacing and mounting requirements. PCB layouts are fully compatible.
