DF3-2S-2R28(05) Equivalent & Substitute Parts

Part Overview

The DF3-2S-2R28(05) is a 2-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for IDC (Insulation Displacement Contact) termination with 28 AWG discrete wire. This connector features tin contact finish, closed-end design, and operates across -55°C to 105°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-2S-2R28(05) is determined by the following critical parameters that must remain consistent:

• Series designation (DF3)
• Connector type (Receptacle)
• Number of positions (2)
• Pitch specification (0.079" / 2.00mm)
• Contact type (Female Socket)
• Color (Black)
• Base product number (DF3-2)

The primary substitute, DF3-2S-2C, maintains all these core parameters. However, the termination method differs: the original part uses IDC termination, while the substitute uses crimp termination. This represents a functional change in how the connector interfaces with the cable assembly. The substitute is supplied as a housing only, with contacts sold separately, whereas the original part includes integrated IDC contacts.

Parameter Comparison

Engineering Selection Recommendations

The DF3-2S-2C serves as the active-status substitute for the obsolete DF3-2S-2R28(05). Both connectors share identical mechanical and electrical interface specifications: 2-position, 2.00mm pitch, female socket receptacle configuration within the DF3 series.

Selection of the substitute requires evaluation of termination method compatibility. The original part employs IDC termination, which provides simultaneous wire insertion and contact engagement. The substitute uses crimp termination, requiring separate contact insertion into the housing. This difference necessitates assessment of existing cable assembly processes and contact availability.

The substitute maintains current RoHS3 compliance and carries active product status, ensuring ongoing availability and manufacturer support. Both parts share unlimited moisture sensitivity rating, suitable for standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can DF3-2S-2C directly replace DF3-2S-2R28(05) in existing assemblies?

A: Mechanical and electrical interfaces are compatible due to identical pitch, position count, and contact configuration. However, termination method differs: IDC versus crimp. Cable assembly procedures must be evaluated for compatibility with crimp termination.

Q: Are contacts included with the DF3-2S-2C substitute?

A: No. The DF3-2S-2C is supplied as a housing only. Contacts must be sourced separately and inserted into the housing using crimp termination procedures.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active status indicates the substitute part is currently manufactured and supported by Hirose Electric Co Ltd, ensuring long-term availability and supply chain reliability compared to the obsolete original part.

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

A: Both parts are RoHS compliant. The substitute carries ROHS3 certification, representing current regulatory compliance standards. Both maintain unlimited MSL rating.

Q: What determines substitution eligibility for DF3 series connectors?

A: Core parameters include series designation, connector type (receptacle), position count (2), pitch (2.00mm), contact type (female socket), and mounting configuration (free hanging in-line). Termination method and contact inclusion represent secondary variables affecting implementation.
