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

Part Overview

The DF3-2S-2R26(05) is a 2-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd. This connector features IDC (Insulation Displacement Contact) termination with tin contact finish and 26 AWG wire gauge capability. 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 eligibility for the DF3-2S-2R26(05) is determined by the following critical parameters:

• Series alignment: DF3 series designation
• Connector type and contact configuration: Receptacle with female socket contacts
• Position count: 2-position configuration
• Pitch specification: 0.079" (2.00mm) contact spacing
• Row configuration: Single row layout
• Mounting style: Free hanging in-line orientation
• Color specification: Black housing

The substitute part DF3-2S-2C shares all these core parameters. However, the termination method differs: the main part uses IDC termination while the substitute uses crimp termination. This represents a functional substitution where the connector housing and contact arrangement remain compatible with the DF3 series ecosystem, but the cable attachment method requires process adjustment.

Parameter Comparison

Engineering Selection Recommendations

The DF3-2S-2C serves as the active-production substitute for the obsolete DF3-2S-2R26(05). Both components maintain identical mechanical and electrical compatibility within the DF3 series, including connector pitch, position count, row configuration, and mounting orientation.

The primary distinction is termination methodology. The main part employs IDC termination, which provides tool-free cable attachment. The substitute utilizes crimp termination, requiring dedicated crimping equipment and contacts. This transition aligns with current manufacturing practices, as the substitute maintains active product status with enhanced RoHS3 compliance certification.

Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions. The substitute's specified operating temperature range of -55°C to 105°C provides explicit thermal performance documentation absent from the main part specification.

Selection between these components depends on available assembly infrastructure. IDC-equipped systems should evaluate the substitute's crimp-based approach against process modification requirements. The substitute's active status and current compliance certifications support long-term supply chain stability.

Frequently Asked Questions (FAQ)

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

A: Mechanical and electrical compatibility is maintained. The connector housings, contact arrangements, pitch specifications, and mounting configurations are identical. However, cable termination differs: IDC versus crimp. Existing IDC-terminated cables require re-termination using crimp contacts and appropriate tooling.

Q: What is the significance of the termination method difference?

A: IDC termination pierces wire insulation without stripping, enabling rapid assembly. Crimp termination requires individual contact crimping onto stripped wire ends. Both methods achieve equivalent electrical performance when properly executed. Process selection depends on available equipment and production volume requirements.

Q: Why is the main part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The DF3-2S-2C represents the active-production equivalent within the DF3 series, ensuring continued component availability and supply chain support.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The substitute carries ROHS3 certification, representing current regulatory compliance standards. The main part's RoHS status meets earlier compliance requirements. Both maintain MSL 1 rating for moisture sensitivity.

Q: Does the substitute include contacts?

A: The DF3-2S-2C is supplied as a housing only. Crimp contacts must be sourced separately and assembled according to Hirose specifications. The main part's IDC design integrates contacts within the assembly.

Q: What wire gauges are compatible with the substitute?

A: The substitute's crimp contact selection determines wire gauge compatibility. Hirose provides contact options across standard AWG ranges. Specific contact part numbers must be referenced for 26 AWG wire compatibility verification.
