DF3-14S-2R28(05) Equivalent & Substitute Parts

Part Overview

The DF3-14S-2R28(05) is a 14-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for discrete wire termination using insulation displacement contact (IDC) technology. This connector features tin-plated female socket contacts rated for 28 AWG wire gauge with a 0.079" (2.00mm) pitch configuration.

The DF3-14S-2R28(05) is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and field service requirements for systems utilizing this connector series.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-14S-2R28(05) is determined by the following critical parameters that must remain constant:

• Series Compatibility: Both parts must belong to the DF3 series
• Connector Type & Contact Type: Receptacle with female socket contacts
• Position Count: 14 positions
• Pitch: 0.079" (2.00mm) spacing
• Row Configuration: Single row
• Mounting Type: Free Hanging (In-Line)
• Color: Black
• RoHS Compliance: Maintained across substitutes

The substitute part DF3-14S-2C shares all critical mechanical and electrical parameters with the main part. The primary difference lies in the cable termination method: the main part uses IDC termination, while the substitute uses crimp termination. Both termination methods are valid connection technologies within the DF3 series and maintain full compatibility with the connector housing and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF3-14S-2C is the manufacturer-recommended substitute for the obsolete DF3-14S-2R28(05). Selection of this substitute is supported by the following factors:

Product Status: The DF3-14S-2C maintains active product status with Hirose Electric Co Ltd, ensuring ongoing availability and supply chain support. The main part is classified as obsolete, making the substitute the appropriate choice for new designs and ongoing production.

Compliance & Certifications: Both parts maintain RoHS compliance. The substitute achieves ROHS3 compliance, representing current regulatory standards. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent environmental performance.

Mechanical & Electrical Compatibility: The substitute maintains identical mechanical dimensions, pitch spacing, position count, and mounting configuration. The connector housing and contact interface specifications remain unchanged, ensuring direct compatibility with existing mating components and cable assemblies.

Termination Method Consideration: The primary technical difference is the cable termination method. The main part uses IDC termination, while the substitute uses crimp termination. Both methods are established connection technologies within the DF3 series. Selection between these termination methods depends on existing assembly equipment and process requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF3-14S-2C directly replace the DF3-14S-2R28(05) in existing assemblies?

A: The DF3-14S-2C is mechanically and electrically compatible with the DF3-14S-2R28(05) for mating with plug connectors and cable routing. However, the cable termination method differs: the main part uses IDC termination while the substitute uses crimp termination. Compatibility depends on whether your assembly process and equipment support crimp termination.

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

A: IDC (Insulation Displacement Contact) termination pierces the wire insulation during insertion, while crimp termination requires a separate crimping tool to attach contacts to wires. Both methods are valid within the DF3 series and produce reliable connections when properly executed with appropriate equipment.

Q: Are there any differences in contact finish between these parts?

A: The main part specifies tin contact finish. The substitute part does not specify contact finish in the provided data. Contact finish specifications should be verified with Hirose Electric Co Ltd if contact material compatibility is critical for your application.

Q: Why is the main part classified as obsolete?

A: The DF3-14S-2R28(05) is no longer in active production. The DF3-14S-2C represents the current active product offering from Hirose Electric Co Ltd for this connector configuration and should be used for new designs and ongoing production requirements.

Q: Are both parts RoHS compliant?

A: Yes. The main part is RoHS Compliant, and the substitute is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature range for these connectors?

A: The substitute part specifies an operating temperature range of -55°C to 105°C. The main part does not provide operating temperature specifications in the available data. For critical temperature applications, verify operating specifications with the manufacturer.
