Engineering Selection Recommendations

Both DF11-16DP-2DS(24) and DF11-16DP-2DS(52) are functionally equivalent substitutes for the obsolete DF11-16DP-2DS(22) based on identical mechanical and electrical specifications.

DF11-16DP-2DS(24) is recommended for applications requiring tin-plated contact finish with standard environmental specifications. This part is active, ROHS3 compliant, and available in tube packaging with 1139 units in stock.

DF11-16DP-2DS(52) is recommended for applications requiring gold-plated contact finish, which provides enhanced corrosion resistance and contact reliability in demanding environments. This part is active, ROHS3 compliant, and available in tube packaging with 1077 units in stock.

Both substitutes support the extended operating temperature range of -40°C to 85°C, compared to the original part's -30°C to 85°C specification, providing improved thermal performance margins.

Frequently Asked Questions (FAQ)

Q: Are DF11-16DP-2DS(24) and DF11-16DP-2DS(52) mechanically interchangeable with DF11-16DP-2DS(22)?

A: Yes. Both substitutes maintain identical mechanical specifications including 16 positions, 2-row configuration, 2.00mm pitch, through-hole right-angle mounting, and shrouded 4-wall design. Direct board-level substitution is supported without PCB redesign.

Q: What is the difference between the tin-plated DF11-16DP-2DS(24) and gold-plated DF11-16DP-2DS(52)?

A: The primary difference is contact finish. DF11-16DP-2DS(24) features tin plating at 1.00µm thickness, while DF11-16DP-2DS(52) features gold plating at 0.203µm thickness. Gold plating provides superior corrosion resistance and is preferred for high-reliability applications or environments with corrosive exposure.

Q: Why is the original DF11-16DP-2DS(22) classified as obsolete?

A: The original part is obsolete and has been superseded by active alternatives. Both substitute parts offer improved compliance status (ROHS3 compliant versus RoHS non-compliant) and extended operating temperature range.

Q: Are there compliance differences between the original and substitute parts?

A: Yes. The original DF11-16DP-2DS(22) is RoHS non-compliant, while both substitutes DF11-16DP-2DS(24) and DF11-16DP-2DS(52) are ROHS3 compliant. All three parts maintain identical REACH and ECCN classifications.

Q: What is the operating temperature difference between the original and substitutes?

A: The original DF11-16DP-2DS(22) operates from -30°C to 85°C. Both substitutes extend the lower temperature limit to -40°C, providing a 10°C improvement in cold-temperature performance.

Q: Are both substitutes available in the same packaging format?

A: Yes. Both DF11-16DP-2DS(24) and DF11-16DP-2DS(52) are supplied in tube packaging, consistent with standard production formats for this connector series.
