DF11-26DP-2DSA(72) Equivalent & Substitute Parts

Part Overview

The DF11-26DP-2DSA(72) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications with through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The original part's discontinuation necessitates evaluation of compatible alternatives that maintain functional equivalence within the DF11 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the DF11 series is determined by the following critical parameters:

• Pitch and Position Spacing: Mating pitch of 0.079" (2.00mm) and row spacing of 0.079" (2.00mm) establish the fundamental mechanical interface
• Connector Type and Mounting: Header configuration with through-hole solder termination
• Shrouding Configuration: Shrouded 4-wall design for mechanical stability
• Electrical Ratings: 250V voltage rating and 2A current rating per contact
• Contact Material and Finish: Tin-plated brass contacts
• Operating Temperature Range: -30°C to 85°C thermal envelope
• Flammability Compliance: UL94 V-0 material rating

The DF11-18DP-2DSA(08) qualifies as a substitute based on shared series designation, identical pitch specifications, matching shrouding type, equivalent electrical ratings, and compatible termination method. The primary distinction is the reduced position count (18 positions versus 26 positions), which represents a functional subset of the original part's capability.

Parameter Comparison

Engineering Selection Recommendations

The DF11-18DP-2DSA(08) is an active production component with ROHS3 compliance and MSL Level 1 rating, providing superior procurement stability compared to the obsolete DF11-26DP-2DSA(72). Both components share identical electrical specifications, mechanical pitch, shrouding configuration, and operating temperature range.

Selection of the substitute part requires verification that the reduced position count (18 versus 26) aligns with circuit requirements. Applications utilizing fewer than 18 signal connections can directly adopt the DF11-18DP-2DSA(08) without modification to mating connector geometry or PCB footprint spacing. Applications requiring all 26 positions necessitate evaluation of alternative DF11 series variants with matching position counts or consideration of connector family alternatives outside the DF11 series.

Frequently Asked Questions (FAQ)

Q: Can the DF11-18DP-2DSA(08) directly replace the DF11-26DP-2DSA(72) in existing designs?

A: Direct replacement is possible only if the application uses 18 or fewer signal connections. The mating pitch (0.079"), row spacing (0.079"), shrouding type, and electrical ratings are identical. PCB footprint compatibility depends on position count requirements.

Q: What is the primary difference between these two connectors?

A: The DF11-26DP-2DSA(72) provides 26 mating positions in a 2-row configuration, while the DF11-18DP-2DSA(08) provides 18 mating positions in a 2-row configuration. All other mechanical and electrical parameters are equivalent.

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

A: The DF11-18DP-2DSA(08) carries ROHS3 compliance certification and MSL Level 1 rating, whereas the obsolete DF11-26DP-2DSA(72) does not specify these certifications. Both maintain UL94 V-0 flammability rating and equivalent electrical performance.

Q: What packaging is available for the substitute part?

A: The DF11-18DP-2DSA(08) is supplied in bulk packaging with 7900 pieces available in current inventory.

Q: Are the contact specifications identical between both parts?

A: Yes. Both connectors use tin-plated brass contacts with 0.118" (3.00mm) mating contact length, 0.118" (3.00mm) post length, and 0.299" (7.60mm) overall contact length. Contact finish thickness on mating surfaces is 39.4µin (1.00µm) for both parts.
