DF3-3S-2R26(01) Equivalent & Substitute Parts

Part Overview

The DF3-3S-2R26(01) is a 3-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd. This connector features IDC (Insulation Displacement Contact) termination with gold-plated contacts rated for 26 AWG wire. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-3S-2R26(01) is determined by the following critical parameters that must remain consistent:

• Series Compatibility: Both parts must belong to the DF3 series to ensure mechanical and electrical compatibility
• Position Count: 3-position configuration must be maintained
• Pitch Specification: 0.079" (2.00mm) pitch is mandatory for proper mating alignment
• Connector Type: Receptacle configuration with female socket contacts
• Row Configuration: Single-row layout
• Contact Finish: Gold plating for corrosion resistance and electrical performance

The DF3-3S-2C qualifies as a substitute based on these parameters. However, a critical distinction exists: the DF3-3S-2R26(01) includes integrated IDC contacts, while the DF3-3S-2C is a housing-only component supplied without contacts. This difference requires evaluation based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DF3-3S-2C serves as the active-status equivalent within the DF3 series. Selection between these components depends on termination methodology:

DF3-3S-2R26(01) is suitable for applications requiring IDC termination with integrated contacts. This configuration is now obsolete; existing inventory is limited to 709 pieces.

DF3-3S-2C is the recommended path forward for new designs and ongoing procurement. This housing component is actively manufactured with 5,080 pieces in current inventory. The DF3-3S-2C requires separate contact procurement and crimp termination assembly, providing flexibility for custom wire gauge and contact material specifications within the DF3 series ecosystem.

Both components maintain RoHS compliance and identical moisture sensitivity ratings, supporting regulatory requirements across applications.

Frequently Asked Questions (FAQ)

Q: Can DF3-3S-2C directly replace DF3-3S-2R26(01) in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for the housing and contact interface. However, the DF3-3S-2C does not include integrated contacts. Replacement requires procurement of compatible DF3 series contacts and assembly using crimp termination instead of IDC termination.

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

A: The DF3-3S-2R26(01) uses IDC (Insulation Displacement Contact) termination, which pierces wire insulation during assembly. The DF3-3S-2C uses crimp termination, requiring separate contact components and a crimping tool for wire attachment.

Q: Are there compatibility concerns with pitch or position count?

A: No. Both components maintain identical 0.079" (2.00mm) pitch and 3-position configuration, ensuring proper mating with corresponding plug connectors in the DF3 series.

Q: What is the inventory status for each part?

A: DF3-3S-2R26(01) has 709 pieces available as new original stock. DF3-3S-2C has 5,080 pieces available as new original stock in bulk packaging.

Q: Do both parts meet current regulatory standards?

A: Yes. DF3-3S-2R26(01) is RoHS Compliant. DF3-3S-2C is ROHS3 Compliant, representing the current regulatory standard. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.
