DF3-3S-2R26(05) Equivalent & Substitute Parts

Part Overview

The DF3-3S-2R26(05) is a 3-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd. This connector features IDC (Insulation Displacement Contact) termination with 26 AWG wire gauge and tin contact finish. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-3S-2R26(05) is determined by the following critical parameters that must remain constant:

• Series designation (DF3)
• Connector type (Receptacle)
• Number of positions (3)
• Pitch specification (0.079" / 2.00mm)
• Contact type (Female Socket)
• Mounting configuration (Free Hanging In-Line)

The primary substitute identified is the DF3-3S-2C, which maintains all critical mechanical and electrical parameters. The key distinction is the termination method: the DF3-3S-2C uses crimp termination rather than IDC termination, and is supplied as a housing without contacts included.

Parameter Comparison

Engineering Selection Recommendations

The DF3-3S-2C serves as the active-status equivalent for the obsolete DF3-3S-2R26(05). Both components share identical mechanical dimensions, pitch, and contact configuration, ensuring physical and electrical compatibility within the DF3 series framework.

The DF3-3S-2C is supplied as a housing assembly without contacts included. Implementation requires separate procurement of compatible crimp contacts and manual termination, whereas the original DF3-3S-2R26(05) utilized pre-assembled IDC termination. The DF3-3S-2C achieves ROHS3 compliance, exceeding the RoHS compliance level of the original component.

Selection of the DF3-3S-2C is appropriate for applications where the connector housing and contact configuration are the primary functional requirements and where crimp termination methodology is acceptable within system design parameters.

Frequently Asked Questions (FAQ)

Q: Can the DF3-3S-2C directly replace the DF3-3S-2R26(05) in existing assemblies?

A: The DF3-3S-2C housing is mechanically and electrically compatible with the DF3-3S-2R26(05). However, termination method differs: the original uses IDC termination while the substitute requires crimp termination. Existing IDC-terminated cables cannot be directly mated without retermination.

Q: What is the significance of the DF3-3S-2C being supplied without contacts?

A: The DF3-3S-2C is a housing component. Contacts must be procured separately and crimped into the housing. This modular approach allows flexibility in contact material and finish selection based on specific application requirements.

Q: Are the pitch and position count identical between these parts?

A: Yes. Both the DF3-3S-2R26(05) and DF3-3S-2C maintain 0.079" (2.00mm) pitch and 3-position configuration, ensuring mechanical interchangeability at the connector interface level.

Q: What compliance certifications apply to the substitute part?

A: The DF3-3S-2C carries ROHS3 compliance and REACH Unaffected status. The original DF3-3S-2R26(05) is RoHS Compliant. Both components have MSL rating of 1 (Unlimited).

Q: Is the DF3-3S-2C available in production quantities?

A: The DF3-3S-2C is classified as Active product status with documented inventory availability, whereas the DF3-3S-2R26(05) is obsolete with limited remaining stock.
