DF3-5S-2R28(05) Equivalent & Substitute Parts

Part Overview

The DF3-5S-2R28(05) is a 5-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 tin contact finish, closed-end housing, 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 eligibility for the DF3-5S-2R28(05) is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the DF3 series to ensure mechanical and electrical interchangeability
• Position Count: Substitute must maintain 5-position configuration
• Pitch Specification: Contact pitch must remain 0.079" (2.00mm) for proper mating alignment
• Connector Type & Contact Type: Receptacle with female socket contacts required
• Mounting Configuration: Free hanging (in-line) mounting type must be preserved
• Electrical Compliance: RoHS compliance status must be maintained or upgraded

The DF3-5S-2C qualifies as a manufacturer-recommended substitute based on these parameters. However, a critical distinction exists: the DF3-5S-2C is a housing-only component (contacts not included), whereas the DF3-5S-2R28(05) includes pre-assembled IDC contacts. This difference requires evaluation of your specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The DF3-5S-2R28(05) is classified as obsolete, while the DF3-5S-2C is active. For new designs or long-term system support, the active substitute is the appropriate choice.

Compliance Upgrade: The DF3-5S-2C offers ROHS3 compliance, which represents an enhanced regulatory status compared to the RoHS Compliant designation of the main part.

Termination Method Difference: The primary technical distinction is the cable termination method. The main part uses IDC termination, while the substitute uses crimp termination. This difference impacts assembly methodology and requires corresponding contact selection. The DF3-5S-2C housing must be paired with appropriate DF3 series crimp contacts to achieve functional equivalence.

Availability: The DF3-5S-2C demonstrates significantly higher inventory availability (500,400 pcs) compared to the main part (773 pcs), supporting long-term sourcing reliability.

Frequently Asked Questions (FAQ)

Q: Can the DF3-5S-2C directly replace the DF3-5S-2R28(05) in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for the housing and connector interface. However, the DF3-5S-2C requires separate contact procurement and assembly, as it is supplied as a housing-only component. The main part includes pre-assembled IDC contacts. Direct plug-in replacement is not possible without contact assembly.

Q: What contact types are compatible with the DF3-5S-2C housing?

A: The provided specifications do not include detailed contact compatibility information. Contact selection must be based on DF3 series specifications from the manufacturer.

Q: Are there differences in operating temperature ranges?

A: The DF3-5S-2C specifies an operating temperature range of -55°C to 105°C. The main part specifications do not include operating temperature data in the provided parameters.

Q: Does the substitute meet the same regulatory requirements?

A: Both parts are classified under ECCN EAR99 and HTSUS 8536.69.8000. The DF3-5S-2C provides enhanced RoHS compliance (ROHS3) and is REACH Unaffected. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the "Contacts Not Included" note for the DF3-5S-2C?

A: This indicates the part is supplied as a housing assembly only. Contacts must be sourced separately and assembled into the housing to create a functional connector. This differs from the main part, which includes factory-assembled IDC contacts.
