DF3-14S-2R26(05) Equivalent & Substitute Parts

Part Overview

The DF3-14S-2R26(05) is a 14-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for discrete wire termination using Insulation Displacement Contact (IDC) technology with 26 AWG wire gauge. This connector features a tin contact finish and closed-end housing in black, with a 0.079" (2.00mm) pitch configuration suitable for free-hanging in-line applications.

The DF3-14S-2R26(05) is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3-14S-2R26(05) is determined by the following critical parameters that must remain constant:

• Series: DF3
• Connector Type: Receptacle
• Number of Positions: 14
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Contact Type: Female Socket
• Color: Black
• Mounting Type: Free Hanging (In-Line)

The substitute part DF3-14S-2C shares all these core parameters. However, the termination method differs: the main part uses IDC (Insulation Displacement Contact) termination for 26 AWG discrete wire, while the substitute uses crimp termination and is supplied as a housing without contacts included. This distinction is critical for application compatibility assessment.

Parameter Comparison

Engineering Selection Recommendations

The DF3-14S-2C is the manufacturer-recommended substitute for the DF3-14S-2R26(05). Both parts share identical mechanical and electrical interface specifications within the DF3 series, ensuring physical and functional compatibility at the connector housing level.

The primary distinction is termination methodology. The main part includes pre-assembled IDC contacts for 26 AWG discrete wire, while the substitute is supplied as a housing only, requiring separate procurement and assembly of crimp contacts. This substitution is valid when the application can accommodate crimp termination in place of IDC termination, or when the housing replacement is the primary requirement.

Both parts maintain RoHS compliance. The substitute part carries active product status, ensuring continued availability and supply chain support compared to the obsolete main part. The substitute's specified operating temperature range of -55°C to 105°C and polyamide insulation material provide documented thermal and material specifications not listed for the main part.

Frequently Asked Questions (FAQ)

Q: Can the DF3-14S-2C directly replace the DF3-14S-2R26(05) in existing assemblies?

A: Physical and electrical interface compatibility is confirmed. However, termination method compatibility must be verified. The main part uses IDC termination; the substitute requires crimp termination. If the application is designed exclusively for IDC-terminated connections, additional engineering assessment is required.

Q: What is the significance of "Contacts Not Included" for the DF3-14S-2C?

A: The DF3-14S-2C is supplied as a housing only. Crimp contacts must be procured separately and assembled into the housing. This allows flexibility in contact material and finish selection but requires additional assembly steps compared to the pre-assembled main part.

Q: Are both parts RoHS compliant?

A: Yes. The main part is RoHS Compliant. The substitute part is ROHS3 Compliant, representing a more recent RoHS certification standard.

Q: What are the key parameters that must match for substitution within the DF3 series?

A: Series designation, connector type (receptacle), position count (14), pitch (2.00mm), row configuration (1 row), contact type (female socket), color (black), and mounting type (free hanging in-line) must remain constant for valid substitution.

Q: Does the substitute part support 26 AWG wire?

A: The DF3-14S-2C is supplied without contacts. Wire gauge compatibility depends on the crimp contacts selected during assembly. Verify that chosen contacts support 26 AWG wire if this specification is required.
