DF3-15S-2R26(05) Equivalent & Substitute Parts

Part Overview

The DF3-15S-2R26(05) is a 15-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 DF3-15S-2R26(05) is determined by the following critical parameters that must remain constant:

• Series: DF3
• Number of Positions: 15
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Connector Type: Receptacle
• Contact Type: Female Socket
• Color: Black
• Mounting Type: Free Hanging (In-Line)

The primary substitute identified is the DF3-15S-2C, which maintains all critical mechanical and electrical compatibility parameters. The key distinction is the termination method: the DF3-15S-2C uses crimp termination rather than IDC termination. This represents a functional substitution where the connector housing and contact configuration remain identical, but the wire attachment method differs. The DF3-15S-2C is supplied as a housing without pre-installed contacts, requiring separate procurement and assembly of crimp contacts.

Parameter Comparison

Engineering Selection Recommendations

The DF3-15S-2C is the designated substitute for the obsolete DF3-15S-2R26(05). Selection of this substitute is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance exceeds the RoHS compliance of the original part, meeting current regulatory requirements
• Identical mechanical interface (pitch, number of positions, mounting configuration) ensures physical compatibility
• Same connector series (DF3) and housing design maintain form factor compatibility
• The transition from IDC to crimp termination requires assembly process modification but does not affect connector interface specifications

Implementation of the DF3-15S-2C requires procurement of compatible crimp contacts separately, as this part is supplied as a housing only. Wire gauge and contact finish specifications should be selected based on application requirements and matched to the crimp contact specifications.

Frequently Asked Questions (FAQ)

Q: Can the DF3-15S-2C directly replace the DF3-15S-2R26(05) in existing assemblies?

A: The DF3-15S-2C housing is mechanically and electrically compatible with the DF3-15S-2R26(05). However, the termination method differs: the original part uses IDC termination while the substitute uses crimp termination. Existing IDC-terminated cables cannot be directly mated to the DF3-15S-2C housing. New cable assemblies with crimp-terminated contacts must be prepared.

Q: What is the difference between IDC and crimp termination?

A: IDC (Insulation Displacement Contact) termination pierces the wire insulation during mating, eliminating the need to strip wire ends. Crimp termination requires separate contact crimping onto prepared wire ends before insertion into the housing. Both methods achieve electrical connection but use different assembly processes.

Q: Are contacts included with the DF3-15S-2C?

A: No. The DF3-15S-2C is supplied as a housing only. Crimp contacts must be procured separately and crimped onto wire conductors before assembly into the housing.

Q: What wire gauge should be used with the DF3-15S-2C?

A: Wire gauge selection should be based on application current requirements and the specifications of the crimp contacts selected. The original DF3-15S-2R26(05) specifies 26 AWG; equivalent crimp contact specifications should be verified with the contact manufacturer.

Q: Is the DF3-15S-2C RoHS compliant?

A: Yes. The DF3-15S-2C is ROHS3 compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment.
