Engineering Selection Recommendations

DF206S-G (Comchip Technology) is the manufacturer-recommended substitute. This part maintains active product status and carries ROHS3 compliance certification. The DF206S-G is electrically and mechanically identical to the DF206SP-G, with identical electrical specifications and the same 4-SMD, Gull Wing package configuration. The primary distinction is product status: DF206S-G is in active production, ensuring long-term availability and supply chain continuity.

DF206S (HY Electronic) is a parametric equivalent from an alternative manufacturer. This part meets all electrical and mechanical specifications of the DF206SP-G and carries ROHS3 compliance. The DF206S is suitable for applications where multi-source qualification is acceptable. Moisture sensitivity level is specified as 1 (Unlimited), matching the DF206S-G.

Both substitute parts are suitable for direct replacement in applications currently using the DF206SP-G, provided that multi-source or alternative-manufacturer components are acceptable within the design and procurement framework.

Frequently Asked Questions (FAQ)

Q: Can DF206S-G be used as a direct replacement for DF206SP-G?

A: Yes. The DF206S-G is electrically and mechanically identical to the DF206SP-G. Both parts share identical voltage ratings (600 V peak reverse), current ratings (2 A average rectified), forward voltage characteristics (1.1 V @ 2 A), reverse leakage specifications (10 µA @ 600 V), operating temperature range (-55°C ~ 150°C), and package configuration (4-SMD, Gull Wing, DFS). The DF206S-G is the manufacturer-recommended substitute and is in active production.

Q: What is the difference between DF206S-G and DF206S?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The primary difference is manufacturer: DF206S-G is manufactured by Comchip Technology, while DF206S is manufactured by HY Electronic (Cayman) Limited. Both carry ROHS3 compliance and MSL 1 (Unlimited) ratings. Selection between these parts depends on multi-source qualification requirements and procurement preferences.

Q: Are there any compliance differences between the substitute parts and the original DF206SP-G?

A: The substitute parts DF206S-G and DF206S both carry ROHS3 compliance certification. The original DF206SP-G compliance status is not specified in the available data. Both substitute parts are REACH-affected or REACH-compliant, ensuring regulatory alignment with current environmental standards.

Q: Can the DF206S from HY Electronic be used in applications originally designed for the DF206SP-G?

A: Yes. The DF206S meets all electrical and mechanical requirements of the DF206SP-G. Both parts operate within the same voltage and current parameters, share identical thermal characteristics, and use the same surface-mount package configuration. Selection of the HY Electronic DF206S is appropriate when multi-source component qualification is permitted.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: The substitute parts DF206S-G and DF206S both carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling. This specification is not provided for the original DF206SP-G.
