DF11-4DP-2DS(22) Equivalent & Substitute Parts

Part Overview

The DF11-4DP-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 shrouded 4-position connector operates at 2A/250V with a 2.00mm pitch and is currently classified as obsolete. Due to its discontinued status, equivalent substitute parts with active product availability are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-4DP-2DS(22) is determined by strict equivalence across the following critical parameters:

Connector type, pitch, and position count (4-position, 2.00mm pitch, 2 rows)
Mounting configuration (through-hole, right-angle)
Electrical ratings (2A/250V minimum)
Shrouding design (shrouded 4-wall)
Contact material and termination method (brass, solder)
Insulation material and flammability rating (Polyamide/Nylon, UL94 V-0)

The two substitute parts identified—DF11-4DP-2DS(24) and DF11-4DP-2DS(52)—maintain identical mechanical and electrical specifications. Differences exist only in contact finish material and product status, which do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

Both DF11-4DP-2DS(24) and DF11-4DP-2DS(52) are functionally equivalent substitutes for the obsolete DF11-4DP-2DS(22) in terms of mechanical fit and electrical performance.

DF11-4DP-2DS(24) is the primary direct substitute. It maintains tin contact finish identical to the original part, carries active product status with ROHS3 compliance, and offers an extended operating temperature range (-40°C to 85°C versus -30°C to 85°C). This part is recommended for new designs and production transitions.

DF11-4DP-2DS(52) is the manufacturer-recommended alternative, featuring gold contact finish for enhanced corrosion resistance and contact reliability. It also carries active product status and ROHS3 compliance with the same extended temperature range. Selection of this variant is appropriate for applications requiring superior contact durability or operating in corrosive environments.

Both substitutes are ROHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet. Inventory availability is confirmed for both alternatives.

Frequently Asked Questions (FAQ)

Q: Can DF11-4DP-2DS(24) and DF11-4DP-2DS(52) be used interchangeably with DF11-4DP-2DS(22)?

A: Yes. Both parts are mechanically and electrically equivalent. They share identical pitch (2.00mm), position count (4), row configuration (2 rows), mounting type (through-hole right-angle), and electrical ratings (2A/250V). The only differences are contact finish material and product status.

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

A: Tin finish (DF11-4DP-2DS(24)) provides standard corrosion resistance suitable for most applications. Gold finish (DF11-4DP-2DS(52)) offers enhanced contact reliability and superior resistance to oxidation and corrosion, beneficial in high-reliability or harsh environment applications.

Q: Why is the original DF11-4DP-2DS(22) marked as obsolete?

A: The part has been discontinued by the manufacturer. Hirose Electric Co Ltd has transitioned production to the active variants DF11-4DP-2DS(24) and DF11-4DP-2DS(52), which incorporate improved compliance and material specifications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DF11-4DP-2DS(24) and DF11-4DP-2DS(52) are ROHS3 compliant. The original DF11-4DP-2DS(22) is RoHS non-compliant, making the substitutes necessary for applications subject to RoHS regulations.

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

A: The original DF11-4DP-2DS(22) operates from -30°C to 85°C. Both substitutes extend the lower temperature limit to -40°C, providing improved performance in cold environments.

Q: Does packaging differ between the substitute parts?

A: Both DF11-4DP-2DS(24) and DF11-4DP-2DS(52) are supplied in tube packaging. The original part packaging information was not specified in the technical data.
