DF3-10S-2R26(05) Equivalent & Substitute Parts

Part Overview

The DF3-10S-2R26(05) is a 10-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 DF3-10S-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 of the DF3-10S-2R26(05) is determined by the following critical parameters that must remain consistent:

• Series designation: DF3
• Connector type: Receptacle with female socket contacts
• Position count: 10 positions
• Pitch specification: 0.079" (2.00mm)
• Row configuration: Single row
• Mounting style: Free hanging in-line
• Housing color: Black
• RoHS compliance status

The substitute part DF3-10S-2C shares the same base product number (DF3-10S) and maintains all critical mechanical and electrical parameters. However, the termination method differs: the substitute uses crimp termination rather than IDC termination, and the substitute is supplied as a housing only without contacts included.

Parameter Comparison

Engineering Selection Recommendations

The DF3-10S-2C is the manufacturer-recommended substitute for the obsolete DF3-10S-2R26(05). Both parts maintain identical mechanical compatibility through matching pitch, position count, row configuration, and mounting type. The substitute achieves current RoHS3 compliance status, whereas the original part carries RoHS Compliant designation.

Selection of the DF3-10S-2C requires consideration of the termination method change from IDC to crimp. The substitute is supplied as a housing assembly without contacts; contacts must be sourced separately and assembled using crimp termination techniques rather than the IDC method employed in the original part.

Frequently Asked Questions (FAQ)

Q: Can the DF3-10S-2C directly replace the DF3-10S-2R26(05) in existing applications?

A: Mechanical and electrical compatibility is maintained through identical pitch, position count, and row configuration. However, the termination method differs. The original part uses IDC termination with integrated contacts, while the substitute requires separate contact procurement and crimp assembly. Assembly procedures and tooling requirements will differ accordingly.

Q: What is the significance of the DF3-10S-2C being supplied without contacts?

A: The DF3-10S-2C is a housing assembly only. Contacts must be selected and installed separately using crimp termination. This modular approach allows flexibility in contact material and finish selection to match specific application requirements.

Q: Are there compliance differences between the original and substitute parts?

A: The original DF3-10S-2R26(05) carries RoHS Compliant status. The substitute DF3-10S-2C carries ROHS3 Compliant status, representing a more current compliance designation. Both parts meet RoHS requirements.

Q: What wire gauge compatibility should be verified when using the DF3-10S-2C?

A: The original part specifies 26 AWG wire gauge for IDC termination. When using the DF3-10S-2C with crimp termination, contact selection must be verified to support the intended wire gauge range for your application.

Q: Why is the original part classified as obsolete?

A: The DF3-10S-2R26(05) is no longer in active production. The DF3-10S-2C represents the current active alternative within the DF3 series, offering equivalent mechanical specifications with updated termination methodology and compliance status.
