DF3-5S-2R26(05) Equivalent & Substitute Parts

Part Overview

The DF3-5S-2R26(05) is a 5-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete wiring. This connector features tin contact finish, closed-end housing, and is classified as obsolete. Due to its obsolete status, identifying compatible substitute components is essential for ongoing system maintenance, repair, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF3-5S-2R26(05) is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the DF3 series
• Connector Configuration: Receptacle type with 5 positions
• Pitch Specification: 0.079" (2.00mm) contact spacing
• Contact Type: Female socket configuration
• Mounting Style: Free hanging (in-line) orientation
• Number of Rows: Single row configuration

The substitute part DF3-5S-2C meets these core compatibility criteria. However, a significant difference exists in termination method: the original part uses IDC termination, while the substitute uses crimp termination. This represents a functional change requiring assessment of application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DF3-5S-2C is the manufacturer-recommended substitute for the obsolete DF3-5S-2R26(05). Both components share identical mechanical and electrical specifications for connector housing, contact configuration, pitch, and positioning. The substitute maintains RoHS compliance with ROHS3 certification, exceeding the original part's RoHS Compliant status.

The primary distinction is termination methodology: IDC versus crimp. This difference requires evaluation based on existing cable assembly infrastructure and termination equipment availability. The substitute part is supplied as a housing only, with contacts sold separately, whereas the original part includes integrated IDC contacts.

Frequently Asked Questions (FAQ)

Q: Can DF3-5S-2C directly replace DF3-5S-2R26(05) in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for connector housing and contact interface. However, termination method differs: the original uses IDC termination while the substitute requires crimp termination. Compatibility depends on whether your assembly process can accommodate crimp-terminated contacts.

Q: What is the significance of the DF3-5S-2C being supplied as a housing only?

A: The substitute part is a connector housing without pre-installed contacts. Contacts must be procured separately and crimped into the housing. This modular approach provides flexibility in contact material and finish selection but requires separate contact sourcing and assembly capability.

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

A: Yes. Both parts maintain 0.079" (2.00mm) pitch spacing and 5-position configuration, ensuring mechanical interchangeability at the connector interface level.

Q: Does the ROHS3 compliance of the substitute affect compatibility?

A: ROHS3 compliance represents an enhanced regulatory status compared to the original RoHS Compliant designation. This upgrade does not create compatibility issues and may be beneficial for applications with evolving regulatory requirements.

Q: What should be verified before implementing this substitution?

A: Confirm that your termination process can transition from IDC to crimp methodology, verify contact availability and specifications for the DF3 series, and assess whether the housing-only configuration aligns with your assembly workflow.
