DF3-10S-2R28(05) Equivalent & Substitute Parts

Part Overview

The DF3-10S-2R28(05) is a 10-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for IDC (Insulation Displacement Contact) termination with 28 AWG discrete wiring. This connector features a closed-end housing with tin contact finish and operates across a wide temperature range. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-10S-2R28(05) is determined by the following critical parameters that must remain constant:

• Series: DF3
• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 10
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Color: Black

The DF3-10S-2C qualifies as a substitute because it maintains all these core parameters. However, the termination method differs: the original part uses IDC termination, while the substitute uses crimp termination. This represents a functional change in how the connector interfaces with the cable assembly and requires corresponding changes to the mating cable preparation process.

Parameter Comparison

Engineering Selection Recommendations

The DF3-10S-2C is the manufacturer-recommended substitute for the obsolete DF3-10S-2R28(05). Both components maintain identical mechanical and electrical interface specifications, ensuring physical and electrical compatibility within the DF3 series connector family.

The DF3-10S-2C is currently in active production with substantial inventory availability (3132 pcs), compared to the obsolete status of the original part. The substitute achieves ROHS3 compliance, meeting current regulatory requirements for new designs and production runs.

The primary functional difference is the termination method: the original uses IDC termination, while the substitute requires crimp termination. This change necessitates corresponding modifications to cable assembly procedures and tooling. The substitute is supplied as a housing only, with contacts purchased separately, allowing flexibility in contact material and finish selection to match original specifications if required.

Frequently Asked Questions (FAQ)

Q: Can the DF3-10S-2C directly replace the DF3-10S-2R28(05) in existing assemblies?

A: The connectors are mechanically and electrically compatible due to identical pitch, position count, and mounting configuration. However, the termination method differs: IDC versus crimp. Existing IDC-terminated cables cannot be directly mated to the crimp-based substitute without cable re-termination.

Q: What is the significance of the DF3-10S-2C being supplied as a housing only?

A: The DF3-10S-2C housing is sold without pre-installed contacts. Contacts must be sourced and installed separately. This allows selection of contacts with specific finishes and materials to match the original tin-plated specification if required.

Q: Are there mechanical compatibility concerns between the original and substitute?

A: No. Both components share identical pitch (0.079" / 2.00mm), position count (10), row configuration (1 row), and mounting type (free hanging in-line). Physical mating with corresponding plug connectors is identical.

Q: What compliance differences exist between the original and substitute?

A: The original part is RoHS Compliant. The substitute achieves ROHS3 Compliant status, representing a higher regulatory standard. Both are suitable for applications requiring RoHS compliance.

Q: How does the termination method change affect system integration?

A: IDC termination uses insulation displacement contacts that pierce wire insulation without stripping. Crimp termination requires stripped wire ends and mechanical crimping. Cable assembly procedures, tooling, and labor processes differ between these methods.
