DF3-8S-2R28(05) Equivalent & Substitute Parts

Part Overview

The DF3-8S-2R28(05) is an 8-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 components is essential for ongoing system maintenance, repair, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-8S-2R28(05) 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
• Connector Configuration: 8-position receptacle with female socket contacts
• Pitch Specification: 0.079" (2.00mm) pitch for proper mating alignment
• Contact Finish: Tin plating for electrical performance and corrosion resistance
• Housing Color: Black for visual identification and consistency
• Electrical Classification: Rectangular connector category with equivalent current and voltage ratings

The substitute part DF3-8S-2C meets these criteria as a same-series alternative within the DF3 family. However, the termination method differs: the original part uses IDC (Insulation Displacement Contact) termination, while the substitute uses crimp termination. This represents a functional substitution where the housing and contact configuration remain compatible, but the wire attachment method changes.

Parameter Comparison

Engineering Selection Recommendations

The DF3-8S-2C serves as the active-status substitute for the obsolete DF3-8S-2R28(05). Both components share identical mechanical dimensions, pitch specifications, and contact configuration within the DF3 series. The substitute maintains full RoHS compliance and exceeds the original part's environmental specifications with documented operating temperature range.

The primary distinction is termination methodology: the original part accommodates IDC termination for discrete 28 AWG wire, while the substitute requires crimp-style termination. This substitution is valid when the application can accommodate crimp-terminated contacts or when transitioning to crimp-based assembly processes.

The DF3-8S-2C is manufactured by the same original equipment manufacturer (Hirose Electric Co Ltd), ensuring consistent quality and reliability standards. Its active product status provides long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the DF3-8S-2C directly replace the DF3-8S-2R28(05) in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for same-series DF3 receptacle connectors with matching 8-position, 2.00mm pitch configuration. The primary consideration is termination method: the original uses IDC termination while the substitute uses crimp termination. Direct replacement requires compatibility with crimp-style wire attachment.

Q: What is the significance of the different termination methods?

A: IDC (Insulation Displacement Contact) termination pierces wire insulation without stripping, while crimp termination requires pre-stripped wire and a crimping tool. Both methods provide reliable electrical connections; selection depends on assembly equipment and process requirements.

Q: Are there compatibility concerns with the operating temperature range?

A: The substitute part specifies -55°C ~ 105°C operating temperature. The original part does not provide a documented temperature range. If the application operates within the substitute's specified range, thermal compatibility is confirmed.

Q: Does the ROHS3 compliance of the substitute affect compatibility?

A: ROHS3 compliance represents an enhanced environmental standard compared to the original RoHS Compliant designation. The substitute meets or exceeds the original part's compliance requirements, making it suitable for applications with equivalent or stricter environmental standards.

Q: What does "Contacts Not Included" mean for the DF3-8S-2C?

A: The DF3-8S-2C is a housing-only component. Contacts must be sourced separately and inserted into the housing. This modular approach allows customization of contact specifications for specific application requirements.

Q: Is the DF3 series the only source for compatible substitutes?

A: Substitution criteria are strictly limited to the parameters provided. Within the specified parameters, the DF3 series maintains the required mechanical and electrical compatibility for 8-position, 2.00mm pitch rectangular receptacle connectors.
