Substitute Part Grouping Explanation
Substitution eligibility for the DF11-12DP-2DS(22) is determined by strict equivalence across the following critical parameters:
- Connector type, contact type, and position configuration (Header, Male Pin, 12 positions, 2 rows)
- Mating pitch and row spacing (0.079" / 2.00mm)
- Mounting style and orientation (Through Hole, Right Angle)
- Shrouding configuration (Shrouded - 4 Wall)
- Termination method (Solder)
- Fastening mechanism (Detent Lock)
- Contact dimensions and material (Square shape, Brass material)
- Electrical ratings (2A current, 250V voltage)
- Insulation specifications (Polyamide/Nylon, Black, UL94 V-0)
The identified substitute parts DF11-12DP-2DS(24) and DF11-12DP-2DS(52) maintain complete equivalence across all mechanical and electrical parameters. Variations exist only in contact finish specifications and product compliance status, which do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations
Both DF11-12DP-2DS(24) and DF11-12DP-2DS(52) are direct functional equivalents to the obsolete DF11-12DP-2DS(22) and are suitable for replacement in new designs and production applications.
DF11-12DP-2DS(24) is recommended as the primary substitute. This part maintains tin contact finish identical to the original specification, offers ROHS3 compliance, and is actively manufactured with substantial inventory availability (15,265 pcs). The extended operating temperature range (-40°C ~ 85°C) provides improved thermal performance compared to the original part (-30°C ~ 85°C).
DF11-12DP-2DS(52) is recommended as an alternative substitute when enhanced contact reliability is required. This part features gold-plated mating contacts, which provide superior corrosion resistance and contact durability compared to tin plating. It maintains ROHS3 compliance and active product status with comparable inventory levels (12,347 pcs). The gold finish is specified at 8.00µin (0.203µm) thickness.
Both substitutes eliminate the RoHS non-compliance issue of the original part and ensure long-term supply chain continuity through active manufacturing status.
Frequently Asked Questions (FAQ)
Q: Are DF11-12DP-2DS(24) and DF11-12DP-2DS(52) mechanically interchangeable with DF11-12DP-2DS(22)?
A: Yes. Both substitute parts maintain identical mechanical dimensions, mounting configuration, shrouding design, and contact geometry. They are direct mechanical replacements requiring no PCB layout or connector cavity modifications.
Q: What is the difference between the tin and gold contact finishes?
A: DF11-12DP-2DS(24) features tin-plated contacts (matching the original specification), while DF11-12DP-2DS(52) features gold-plated contacts. Gold plating provides enhanced corrosion resistance and is typically specified for applications requiring extended shelf life, high-humidity environments, or superior contact reliability. Both finishes meet the 2A current and 250V voltage ratings.
Q: Why does the operating temperature range differ between the original part and the substitutes?
A: The original DF11-12DP-2DS(22) specifies -30°C ~ 85°C, while both substitutes specify -40°C ~ 85°C. This represents an improvement in the substitute parts, extending the lower temperature limit by 10°C. This does not affect compatibility; applications designed for the original temperature range operate within the substitute parts' specifications.
Q: Are both substitutes RoHS compliant?
A: Yes. Both DF11-12DP-2DS(24) and DF11-12DP-2DS(52) are ROHS3 compliant, eliminating the RoHS non-compliance status of the original DF11-12DP-2DS(22). This is significant for applications subject to RoHS regulations or customer requirements.
Q: What packaging is provided for the substitute parts?
A: Both substitute parts are supplied in tube packaging, which is standard for connector headers and provides protection during storage and handling.
Q: Can I use DF11-12DP-2DS(52) in applications where DF11-12DP-2DS(24) was originally specified?
A: Yes. The gold contact finish of DF11-12DP-2DS(52) is a performance enhancement that does not compromise compatibility. It is electrically and mechanically equivalent to DF11-12DP-2DS(24) and can be used as a direct substitute in any application.
