DF3-4S-2R26(01) Equivalent & Substitute Parts

Part Overview

The DF3-4S-2R26(01) is a 4-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete wiring. This connector features gold-plated contacts, a 2.00mm pitch, and closed-end housing in black. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-4S-2R26(01) is determined by the following critical parameters:

• Series Compatibility: Both main and substitute parts must belong to the DF3 series to ensure mechanical and electrical compatibility
• Position Count: 4-position configuration must be maintained
• Pitch Specification: 2.00mm (0.079") pitch is mandatory for connector alignment and mating
• Connector Type: Receptacle configuration with female socket contacts
• Contact Finish: Gold plating for electrical performance and corrosion resistance
• Housing Color: Black housing for identification and environmental consistency
• Compliance Standards: RoHS compliance required for regulatory adherence

The substitute part DF3-4S-2C shares all critical mechanical and electrical parameters with the main part. The primary difference lies in the termination method: the main part uses IDC termination for discrete 26 AWG wire, while the substitute uses crimp termination. Both are housed within the same DF3 series receptacle housing with identical pitch, position count, and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF3-4S-2C is the manufacturer-recommended substitute for the obsolete DF3-4S-2R26(01). Both connectors maintain identical mechanical dimensions, pitch spacing, and contact specifications within the DF3 series. The substitute part carries active product status with current manufacturing support and improved compliance certification (ROHS3).

Selection of the DF3-4S-2C requires consideration of termination methodology. The main part accommodates IDC termination for discrete wire insertion, while the substitute requires crimp-style contact termination. This difference necessitates corresponding changes to wire preparation and assembly procedures but does not affect the connector housing, mating interface, or electrical performance characteristics.

The substitute part is supplied as a housing-only configuration with contacts not included, whereas the main part includes integrated IDC contacts. Procurement of compatible crimp contacts from the DF3 series is required when implementing the substitute.

Frequently Asked Questions (FAQ)

Q: Can the DF3-4S-2C directly replace the DF3-4S-2R26(01) without modification?

A: The connector housings are mechanically and electrically compatible due to identical pitch, position count, and contact specifications. However, the termination method differs: IDC versus crimp. Wire preparation and assembly procedures must be adapted accordingly.

Q: What is the significance of the "Contacts Not Included" note on the DF3-4S-2C?

A: The DF3-4S-2C is supplied as a housing assembly only. Crimp-style contacts compatible with the DF3 series must be procured separately and installed into the housing. The main part includes pre-installed IDC contacts.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The main part carries RoHS Compliant certification, while the substitute carries ROHS3 Compliant certification, representing an updated compliance standard.

Q: Does the operating temperature range affect substitution suitability?

A: The DF3-4S-2C specifies an operating temperature range of -55°C to 105°C. This parameter is not provided for the main part. Verify that this range meets application requirements before implementation.

Q: What inventory considerations apply to this substitution?

A: The main part has 772 units in stock with obsolete status. The substitute part has 35,400 units in stock with active product status, ensuring long-term availability and supply chain continuity.
