Parameter Comparison

Engineering Selection Recommendations

All three parts—ISP620-2, ISP620-2X, and TLP620-2X—are active production components manufactured by 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.

ISP620-2X and TLP620-2X are direct parametric equivalents to ISP620-2. All three parts carry ROHS3 compliance, REACH unaffected status, and MSL Level 1 (unlimited moisture sensitivity). The 8-DIP through-hole package is consistent across all variants, ensuring PCB layout compatibility without modification.

Current inventory levels are: ISP620-2 (1057 units), ISP620-2X (1056 units), and TLP620-2X (2365 units). Selection may be influenced by stock availability and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can ISP620-2X be used as a direct replacement for ISP620-2?

A: Yes. ISP620-2X maintains identical electrical specifications including isolation voltage (5300Vrms), channel count (2), current transfer ratio (50–600% @ 5mA), output voltage (55V maximum), and output current (50mA per channel). The 8-DIP package dimensions and through-hole mounting are identical. No circuit modifications are required.

Q: What is the difference between ISP620-2 and TLP620-2X?

A: Both parts are dual-channel optoisolators with 5300Vrms isolation and transistor output. All measured electrical parameters are identical. The primary difference is the series designation: ISP620-2 belongs to the ISP620-2 series, while TLP620-2X belongs to the TLP620 base product series. Functionally and mechanically, they are equivalent.

Q: Are all three parts suitable for AC and DC input applications?

A: Yes. ISP620-2, ISP620-2X, and TLP620-2X all support both AC and DC input types, enabling use in applications requiring galvanic isolation for either signal type.

Q: Do these parts require any special handling or storage considerations?

A: All three parts carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control measures are required during storage or handling. Standard component storage practices apply.

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

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. Regulatory and compliance status is equivalent across all variants.
