DF3-3S-2R28(05) Equivalent & Substitute Parts

Part Overview

The DF3-3S-2R28(05) is a 3-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for IDC (Insulation Displacement Contact) termination with 28 AWG discrete wire. This connector features a closed-end housing with tin contact finish and is classified as obsolete. Due to its obsolete status, identifying compatible substitute parts is essential for ongoing system maintenance, repair, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the DF3-3S-2R28(05) is determined by the following critical parameters:

• Series alignment: Both parts must belong to the DF3 series
• Connector type and contact configuration: Receptacle with female socket contacts
• Position count: 3-position configuration
• Pitch specification: 0.079" (2.00mm) contact spacing
• Row configuration: Single row layout
• Housing and mechanical compatibility: Free hanging (in-line) mounting type
• Electrical compliance: RoHS compliance status

The substitute part DF3-3S-2C meets all these criteria as a same-series receptacle connector with identical position count, pitch, row configuration, and mounting type. The primary difference lies in the termination method: the substitute uses crimp termination rather than IDC termination, and is supplied as a housing without integrated contacts.

Parameter Comparison

Engineering Selection Recommendations

The DF3-3S-2C is the designated substitute for the obsolete DF3-3S-2R28(05). Both connectors maintain identical mechanical and electrical compatibility within the DF3 series framework, with matching position count, pitch, row configuration, and mounting specifications.

The DF3-3S-2C offers the advantage of active product status, ensuring continued availability and supply chain reliability. It carries ROHS3 compliance, representing current regulatory standards. The transition from IDC to crimp termination requires corresponding changes in wire preparation and assembly methodology but does not affect connector interchangeability at the mating interface.

Selection of the DF3-3S-2C is appropriate for applications requiring a 3-position, 2.00mm pitch receptacle connector within the DF3 series, provided that crimp termination is compatible with the application's assembly and maintenance procedures.

Frequently Asked Questions (FAQ)

Q: Can the DF3-3S-2C directly replace the DF3-3S-2R28(05) in existing assemblies?

A: The connectors are mechanically and electrically compatible at the mating interface. However, the termination method differs: the original uses IDC termination while the substitute uses crimp termination. Wire preparation and assembly procedures must be adjusted accordingly.

Q: What is the significance of the DF3 series designation?

A: The DF3 series designation indicates a family of rectangular connectors with standardized pitch (2.00mm), row configuration, and mounting type. Parts within this series maintain mechanical compatibility for housing and contact spacing.

Q: Does the DF3-3S-2C include contacts?

A: No. The DF3-3S-2C is supplied as a housing without integrated contacts. Contacts must be sourced separately and installed using crimp termination methods.

Q: Are there compliance differences between the two parts?

A: The original part carries RoHS Compliant status. The substitute carries ROHS3 Compliant status, representing updated regulatory requirements. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What wire gauge compatibility should be considered?

A: The original DF3-3S-2R28(05) is specified for 28 AWG discrete wire with IDC termination. When using the DF3-3S-2C substitute with crimp termination, wire gauge selection must align with the crimp contact specifications for the DF3 series.
