Substitute Part Grouping Explanation

Substitution eligibility for the DF11-26DP-2DS(22) is determined by strict equivalence across the following critical parameters:

• Connector Series: DF11 (all substitutes must belong to the same series)
• Number of Positions: 26 positions
• Number of Rows: 2 rows
• Pitch Configuration: 0.079" (2.00mm) mating pitch and row spacing
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Shrouding: Shrouded - 4 Wall
• Electrical Ratings: 2A current, 250V voltage minimum
• Insulation Material: Polyamide (PA), Nylon
• Material Flammability: UL94 V-0

The identified substitutes DF11-26DP-2DS(24) and DF11-26DP-2DS(52) maintain full equivalence across all critical mechanical and electrical parameters. Variations in contact finish material and product status are secondary characteristics that do not affect functional interchangeability in the connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both DF11-26DP-2DS(24) and DF11-26DP-2DS(52) are functionally equivalent substitutes for the obsolete DF11-26DP-2DS(22). Selection between these alternatives should be based on the following criteria:

DF11-26DP-2DS(24) is the direct manufacturer substitute with tin contact finish matching the original part specification. This variant is ROHS3 compliant and maintains active product status with extended operating temperature range (-40°C ~ 85°C). Packaging is provided in tube format with 1694 units in current inventory.

DF11-26DP-2DS(52) is the manufacturer-recommended alternative featuring gold contact finish for enhanced corrosion resistance and contact reliability. This variant is also ROHS3 compliant with active product status and extended operating temperature range (-40°C ~ 85°C). Packaging is provided in tube format with 1206 units in current inventory.

For applications requiring direct specification compliance with tin finish, DF11-26DP-2DS(24) is the appropriate selection. For applications where enhanced contact durability and corrosion resistance are beneficial, DF11-26DP-2DS(52) with gold finish is the recommended choice. Both parts maintain full electrical and mechanical interchangeability with the original DF11-26DP-2DS(22).

Frequently Asked Questions (FAQ)

Q: Can DF11-26DP-2DS(24) and DF11-26DP-2DS(52) be used interchangeably with DF11-26DP-2DS(22)?

A: Yes. Both substitutes maintain identical mechanical dimensions, pitch configuration, number of positions, mounting type, and electrical ratings. The primary differences are contact finish material and product compliance status, which do not affect connector interface compatibility.

Q: What is the difference between tin and gold contact finishes?

A: Tin finish (DF11-26DP-2DS(24)) provides cost-effective corrosion protection suitable for standard applications. Gold finish (DF11-26DP-2DS(52)) offers superior corrosion resistance and contact reliability, particularly in high-reliability or harsh environment applications. Both finishes maintain equivalent electrical conductivity and mating force characteristics.

Q: Why is the original DF11-26DP-2DS(22) classified as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. Active substitutes DF11-26DP-2DS(24) and DF11-26DP-2DS(52) provide continued availability with improved compliance certifications (ROHS3) and extended operating temperature ranges.

Q: Are there packaging differences between the substitute parts?

A: Both DF11-26DP-2DS(24) and DF11-26DP-2DS(52) are supplied in tube packaging. The original DF11-26DP-2DS(22) packaging specification was not provided in the technical data.

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

A: The original DF11-26DP-2DS(22) operates from -30°C to 85°C. Both substitutes extend the lower temperature limit to -40°C, providing improved performance in cold environment applications while maintaining the same 85°C upper limit.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DF11-26DP-2DS(24) and DF11-26DP-2DS(52) are ROHS3 compliant. The original DF11-26DP-2DS(22) is RoHS non-compliant, making the substitutes suitable for applications requiring RoHS compliance.
