DF3-11S-2R28(05) Equivalent & Substitute Parts

Part Overview

The DF3-11S-2R28(05) is an 11-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd. This connector features IDC (Insulation Displacement Contact) termination with 28 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 DF3-11S-2R28(05) is determined by the following critical parameters that must remain consistent:

• Series designation (DF3)
• Connector type and contact configuration (11-position receptacle, female socket)
• Pitch specification (0.079" / 2.00mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Base product number (DF3-11S)

The primary substitute identified is the DF3-11S-2C, which maintains all critical mechanical and electrical interface parameters. The key distinction between the main part and substitute lies in the termination method: the DF3-11S-2R28(05) uses IDC termination with integrated wire gauge specification, while the DF3-11S-2C is a housing-only component designed for crimp termination. This substitution is valid when the application can accommodate crimp-terminated contacts in place of IDC-terminated assemblies.

Parameter Comparison

Engineering Selection Recommendations

The DF3-11S-2C serves as the active production equivalent for the obsolete DF3-11S-2R28(05). Both components share identical mechanical interfaces, pitch specifications, and connector geometry, ensuring physical and electrical compatibility at the mating interface.

The DF3-11S-2C is classified as active product status with ROHS3 compliance, providing a path forward for applications requiring continued supply and regulatory compliance. The substitute component is supplied as a housing-only assembly; contacts must be sourced separately and terminated using crimp methodology rather than IDC termination.

Selection of the DF3-11S-2C requires confirmation that the application environment and wire termination process can accommodate crimp-terminated contacts. The operating temperature range of -55°C to 105°C specified for the substitute meets or exceeds typical industrial requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF3-11S-2C directly replace the DF3-11S-2R28(05) in existing assemblies?

A: The DF3-11S-2C provides mechanical and electrical interface compatibility. However, the substitute is supplied as a housing without contacts. Replacement requires sourcing compatible crimp contacts and performing termination, as the original IDC termination method is not applicable to the substitute housing.

Q: What is the significance of the pitch specification in substitution?

A: The 0.079" (2.00mm) pitch is a critical parameter that determines physical compatibility with mating connectors and PCB layouts. Both the main part and substitute maintain identical pitch, ensuring direct mechanical compatibility.

Q: Why is the DF3-11S-2C supplied without contacts?

A: The DF3-11S-2C is a housing component designed for modular assembly. This approach allows selection of contacts matched to specific wire gauges and termination requirements. Contact selection must be performed separately based on application wire gauge and termination methodology.

Q: Are there compliance differences between the main part and substitute?

A: The main part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. Both designations indicate compliance with hazardous substance restrictions. ROHS3 represents the current regulatory standard and is applicable to active production components.

Q: What termination method should be used with the DF3-11S-2C?

A: The DF3-11S-2C is designed for crimp termination. IDC termination, used in the original DF3-11S-2R28(05), is not applicable to this housing. Crimp contacts must be selected and terminated according to Hirose specifications for the DF3 series.
