DF11-28DP-2DS(22) Equivalent & Substitute Parts

Part Overview

The DF11-28DP-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 28 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 classified as obsolete, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-28DP-2DS(22) is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Number of positions and row configuration (28 positions, 2 rows)
• Pitch spacing (0.079" / 2.00mm mating pitch and row spacing)
• Mounting style (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Detent Lock)
• Contact length specifications (0.118" / 3.00mm mating and post)
• Insulation height (0.197" / 5.00mm)
• Contact material and shape (Brass, Square)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)
• Current and voltage ratings (2A, 250V)

The identified substitute parts DF11-28DP-2DS(24) and DF11-28DP-2DS(52) maintain full equivalence across all mechanical and electrical parameters. Variations exist only in contact finish specifications and product status, which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both DF11-28DP-2DS(24) and DF11-28DP-2DS(52) are direct functional equivalents to the obsolete DF11-28DP-2DS(22) and are suitable for replacement in new designs and production applications.

DF11-28DP-2DS(24) is classified as Active product status with ROHS3 compliance, tin contact finish, and expanded operating temperature range (-40°C ~ 85°C). This variant provides regulatory compliance for applications subject to RoHS requirements.

DF11-28DP-2DS(52) is classified as Active product status with ROHS3 compliance, gold contact finish, and expanded operating temperature range (-40°C ~ 85°C). The gold plating provides enhanced corrosion resistance and contact reliability in demanding environments. This variant offers the highest inventory availability at 2200 pieces.

Selection between the two active variants depends on application requirements: tin finish for standard applications or gold finish for enhanced contact durability and corrosion resistance.

Frequently Asked Questions (FAQ)

Q: Can DF11-28DP-2DS(24) or DF11-28DP-2DS(52) be used as direct replacements for DF11-28DP-2DS(22)?

A: Yes. Both substitute parts maintain full mechanical and electrical equivalence across all critical parameters including connector type, position count, pitch spacing, mounting configuration, and electrical ratings. The parts are mechanically and electrically interchangeable.

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

A: Contact finish affects corrosion resistance and contact reliability. Tin finish (DF11-28DP-2DS(24)) is suitable for standard applications. Gold finish (DF11-28DP-2DS(52)) provides superior corrosion resistance and is preferred for applications requiring enhanced contact durability or exposure to corrosive environments.

Q: Are there packaging differences between the substitute parts?

A: DF11-28DP-2DS(24) and DF11-28DP-2DS(52) are both supplied in Tube packaging, which differs from the original part's unspecified packaging. Tube packaging is standard for these active variants and does not affect functional performance.

Q: What is the significance of the operating temperature range difference?

A: The original DF11-28DP-2DS(22) operates from -30°C to 85°C, while both substitute parts operate from -40°C to 85°C. The expanded lower temperature limit of the substitutes provides additional operational margin and is fully backward compatible with the original specification.

Q: Why is RoHS compliance important for this substitution?

A: The original part is RoHS non-compliant, while both substitutes are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant variants are necessary. For legacy applications without RoHS requirements, either variant is acceptable.

Q: Which substitute part should be selected for new designs?

A: DF11-28DP-2DS(52) is recommended for new designs due to active product status, highest inventory availability, gold contact finish for enhanced reliability, and ROHS3 compliance. DF11-28DP-2DS(24) is an alternative if tin finish is preferred or cost optimization is required.
