DF3-15S-2R26(01) Equivalent & Substitute Parts

Part Overview

The DF3-15S-2R26(01) is a 15-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd. This connector features IDC (Insulation Displacement Contact) termination with gold-plated contacts rated for 26 AWG wire. 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(01) is determined by the following critical parameters that must remain constant:

• Series designation: DF3
• Connector type: Receptacle
• Number of positions: 15
• Pitch spacing: 0.079" (2.00mm)
• Contact type: Female Socket
• Mounting configuration: Free Hanging (In-Line)
• Base product number: DF3-15S

The primary substitute identified is the DF3-15S-2C, which maintains all core mechanical and electrical compatibility parameters. The key distinction between the main part and substitute lies in the cable termination method: the original uses IDC termination, while the substitute uses crimp termination. Both components share the same housing, pitch, position count, and contact configuration within the DF3 series.

Parameter Comparison

Engineering Selection Recommendations

The DF3-15S-2C serves as the active-status equivalent for the obsolete DF3-15S-2R26(01). Both components are manufactured by Hirose Electric Co Ltd and maintain identical mechanical compatibility, housing dimensions, and contact configuration. The substitute achieves current RoHS3 compliance status, whereas the original part maintains RoHS compliance.

Selection between these components depends on termination method requirements. The original part accommodates IDC termination for discrete wire applications, while the substitute requires crimp-style contact termination. Both maintain equivalent electrical performance characteristics within the DF3 series specification.

The DF3-15S-2C is currently in active production with established inventory availability, making it the preferred choice for new designs and ongoing system support where crimp termination is compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF3-15S-2C directly replace the DF3-15S-2R26(01) in existing assemblies?

A: Mechanical and electrical compatibility is maintained. The primary consideration is termination method: the original uses IDC termination while the substitute uses crimp termination. Housing, pitch, position count, and contact configuration are identical.

Q: What is the difference between IDC and crimp termination in this connector series?

A: IDC (Insulation Displacement Contact) termination pierces the wire insulation during assembly, while crimp termination requires pre-assembled contacts inserted into the housing. Both methods achieve equivalent electrical connection within the DF3 series specification.

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

A: The DF3-15S-2C is supplied as a housing only. Contacts are not included and must be sourced separately for crimp termination assembly.

Q: What is the operating temperature range for the substitute part?

A: The DF3-15S-2C operates across -55°C to 105°C, providing thermal performance suitable for industrial and commercial applications.

Q: Does the substitute part maintain RoHS compliance?

A: Yes. The DF3-15S-2C achieves ROHS3 compliance, exceeding the RoHS compliance status of the original obsolete part.

Q: Are both parts available in the same packaging format?

A: The original part was supplied in standard packaging. The substitute is available in bulk packaging, suitable for production assembly operations.
