DF3-10S-2R26(01) Equivalent & Substitute Parts

Part Overview

The DF3-10S-2R26(01) is a 10-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 maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-10S-2R26(01) is determined by the following critical parameters that must remain constant:

• Series Compatibility: Both parts must belong to the DF3 series to ensure mechanical and electrical interchangeability
• Connector Configuration: 10-position receptacle with female socket contacts
• Pitch Specification: 0.079" (2.00mm) pitch for proper mating alignment
• Mounting Profile: Free hanging (in-line) orientation
• Contact Material: Gold plating for corrosion resistance and electrical performance
• Housing Color: Black polyamide construction

The substitute part DF3-10S-2C shares all these critical parameters. However, the termination method differs: the original part uses IDC (Insulation Displacement Contact) termination, while the substitute uses crimp termination. This represents a functional difference in how the connector interfaces with the cable assembly, requiring evaluation based on the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DF3-10S-2C is the manufacturer-recommended substitute for the obsolete DF3-10S-2R26(01). Both connectors maintain identical mechanical and electrical specifications across all critical parameters: series designation, position count, pitch, mounting configuration, and contact material.

The primary distinction is the termination method. The original part employs IDC termination, which requires no stripping or crimping of wire ends. The substitute uses crimp termination, which requires individual contact crimping prior to insertion into the housing. The substitute part is supplied as a housing only, with contacts not included, necessitating separate procurement of compatible crimp contacts.

Both parts maintain equivalent RoHS compliance status and unlimited moisture sensitivity ratings, ensuring regulatory and environmental performance parity. The substitute's active product status provides assured long-term availability and supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the DF3-10S-2C directly replace the DF3-10S-2R26(01) in existing assemblies?

A: Mechanical and electrical compatibility is maintained. However, the termination method differs. IDC termination (original) and crimp termination (substitute) require different cable preparation procedures. Existing IDC-terminated cables cannot be directly transferred to the crimp-based substitute housing without re-termination.

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

A: IDC (Insulation Displacement Contact) termination pierces the wire insulation without stripping, while crimp termination requires the wire to be stripped and the contact to be mechanically compressed onto the bare conductor. These are distinct assembly processes requiring different tooling and contact designs.

Q: Are the contact specifications identical between the two parts?

A: The DF3-10S-2C is supplied as a housing only, with contacts not included. The original part includes integrated IDC contacts. Crimp contacts must be sourced separately and must be compatible with the DF3 series 2.00mm pitch specification.

Q: Does the substitute part maintain the same environmental ratings?

A: Both parts share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). The substitute specifies an operating temperature range of -55°C to 105°C. The original part's temperature range is not specified in the available documentation.

Q: What is the inventory status of each part?

A: The original DF3-10S-2R26(01) has 902 pieces in stock. The substitute DF3-10S-2C has 3,132 pieces in stock, providing greater availability for new orders and ongoing supply requirements.
