DF11-22DP-2DS(22) Equivalent & Substitute Parts

Part Overview

The DF11-22DP-2DS(22) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-board or cable applications. This connector features 22 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing, shrouded 4-wall construction, and solder termination with detent lock fastening. The part is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design and procurement requirements.

Substitute Part Grouping Explanation

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

• Connector type, contact type, and configuration (Header, Male Pin, 22 positions, 2 rows)
• Pitch and row spacing (0.079" / 2.00mm)
• Mounting style (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Detent Lock)
• Electrical ratings (2A current, 250V voltage)
• Material specifications (Polyamide/Nylon insulation, UL94 V-0)

The identified substitute parts DF11-22DP-2DS(24) and DF11-22DP-2DS(52) maintain full equivalence across all these core parameters. Variations in contact finish material and thickness, operating temperature range, product status, and RoHS compliance are secondary differentiators that do not affect mechanical or electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both DF11-22DP-2DS(24) and DF11-22DP-2DS(52) are direct functional equivalents to the obsolete DF11-22DP-2DS(22) and are suitable for replacement in new designs and production.

DF11-22DP-2DS(24) is recommended as the primary substitute. It maintains tin contact finish identical to the original part, carries active product status, and achieves ROHS3 compliance. The extended operating temperature range (-40°C to 85°C versus -30°C to 85°C) provides additional thermal margin. Packaging is supplied in tube format with 1554 units currently in stock.

DF11-22DP-2DS(52) is recommended as an alternative substitute when enhanced contact reliability is required. This variant features gold plating on mating contacts, which provides superior corrosion resistance and contact durability compared to tin finish. It carries active product status, ROHS3 compliance, and an extended operating temperature range. Inventory availability is higher at 3988 units in stock.

Selection between DF11-22DP-2DS(24) and DF11-22DP-2DS(52) depends on application-specific requirements for contact finish performance and cost considerations. Both parts are mechanically and electrically interchangeable with the original DF11-22DP-2DS(22).

Frequently Asked Questions (FAQ)

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

A: Yes. Both substitute parts maintain identical mechanical specifications including connector type, position count, pitch spacing, mounting style, shrouding design, and termination method. They are direct mechanical replacements.

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

A: DF11-22DP-2DS(24) features tin contact finish, matching the original part. DF11-22DP-2DS(52) features gold contact finish, which provides enhanced corrosion resistance and improved contact reliability in demanding environments. Both finishes are electrically equivalent for standard applications.

Q: Does the extended operating temperature range of the substitute parts affect compatibility?

A: No. The substitute parts support -40°C to 85°C operation, which encompasses the original part's -30°C to 85°C range. This extended capability does not affect compatibility and provides additional thermal margin for applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DF11-22DP-2DS(24) and DF11-22DP-2DS(52) are ROHS3 compliant, whereas the original DF11-22DP-2DS(22) is RoHS non-compliant. This compliance improvement is beneficial for applications subject to RoHS regulations.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are supplied in tube packaging. DF11-22DP-2DS(24) has 1554 units in stock, and DF11-22DP-2DS(52) has 3988 units in stock.

Q: Can I use DF11-22DP-2DS(52) in applications where DF11-22DP-2DS(24) was originally specified?

A: Yes. DF11-22DP-2DS(52) is fully compatible with DF11-22DP-2DS(24) and maintains all mechanical and electrical equivalence. The gold contact finish provides equal or superior performance in all standard applications.
