DF3-9S-2R26(05) Equivalent & Substitute Parts

Part Overview

The DF3-9S-2R26(05) is a 9-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for discrete wire termination using Insulation Displacement Contact (IDC) technology at 26 AWG. This connector features a 0.079" (2.00mm) pitch, tin contact finish, and closed-end housing in black. 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 DF3-9S-2R26(05) is determined by the following critical parameters that must remain constant:

• Series designation (DF3)
• Connector type and contact type (Receptacle, Female Socket)
• Number of positions (9)
• Pitch specification (0.079" / 2.00mm)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line)
• Color (Black)
• RoHS compliance status

The DF3-9S-2C qualifies as a substitute component within the DF3 series. Both parts share identical mechanical and electrical interface specifications: 9-position receptacle configuration, 2.00mm pitch, single-row layout, and free-hanging in-line mounting. The primary distinction lies in the termination method: the main part uses IDC termination for discrete wire connections, while the substitute uses crimp termination and is supplied as a housing-only component without pre-installed contacts.

Parameter Comparison

Engineering Selection Recommendations

The DF3-9S-2C is the designated substitute for the obsolete DF3-9S-2R26(05). Selection of this alternative is supported by the following engineering criteria:

Product Status Transition: The DF3-9S-2C maintains active product status with current manufacturing support, whereas the DF3-9S-2R26(05) is classified as obsolete. This transition ensures long-term component availability and supply chain continuity.

Regulatory Compliance: Both components satisfy RoHS requirements. The substitute achieves ROHS3 compliance, representing current regulatory standards. Both components carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Mechanical Interface Compatibility: The substitute maintains identical mechanical specifications across all critical dimensions: 9-position configuration, 2.00mm pitch, single-row arrangement, and free-hanging in-line mounting. These parameters ensure direct mechanical compatibility with existing connector systems designed for the original part.

Termination Method Consideration: The primary functional difference is the termination approach. The original part uses IDC termination for direct wire insertion, while the substitute requires crimp-style contact termination. The substitute is supplied as a housing-only component; contacts must be sourced and installed separately according to DF3 series specifications.

Frequently Asked Questions (FAQ)

Q: Can the DF3-9S-2C be used as a direct replacement for the DF3-9S-2R26(05)?

A: The DF3-9S-2C is mechanically and electrically compatible as a substitute. Both components share identical pitch, position count, row configuration, and mounting type. The key difference is termination method: the original uses IDC termination, while the substitute requires crimp-style contacts. System redesign may be necessary if the original IDC termination method is integral to the application.

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

A: IDC (Insulation Displacement Contact) termination allows discrete wires to be inserted directly into the connector without prior stripping or crimping. Crimp termination requires individual contacts to be crimped onto wire ends before insertion into the housing. The DF3-9S-2C housing accepts crimp-style contacts and is supplied without pre-installed contacts.

Q: Is the DF3-9S-2C supplied with contacts included?

A: No. The DF3-9S-2C is supplied as a housing-only component. Contacts must be sourced separately and installed according to Hirose DF3 series specifications. Verify contact specifications and compatibility with your application requirements.

Q: Are there any environmental or compliance differences between these parts?

A: Both components are RoHS compliant and carry MSL Rating 1 (Unlimited). The substitute achieves ROHS3 compliance, representing current regulatory standards. Both components are suitable for operating environments within standard industrial temperature and humidity ranges.

Q: Why is the original part classified as obsolete?

A: The DF3-9S-2R26(05) is obsolete due to product lifecycle management by the manufacturer. The DF3-9S-2C represents the current active alternative within the DF3 series, ensuring ongoing availability and manufacturing support for new designs and system maintenance.
