DF3-8S-2R26(05) Equivalent & Substitute Parts

Part Overview

The DF3-8S-2R26(05) is an 8-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete wiring. 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 eligibility for the DF3-8S-2R26(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: 8-position configuration must be maintained
• Pitch Specification: 0.079" (2.00mm) pitch is mandatory for connector alignment and mating
• Connector Type & Contact Type: Receptacle with female socket contacts required
• Contact Finish: Tin finish for electrical performance consistency
• Housing Color: Black housing for visual identification and standardization
• Regulatory Compliance: RoHS compliance status and MSL rating must be equivalent or superior

The substitute part DF3-8S-2C meets all these criteria as an active-status alternative within the DF3 series, maintaining identical mechanical dimensions, pitch, position count, and contact configuration.

Parameter Comparison

Engineering Selection Recommendations

The DF3-8S-2C serves as the active-status substitute for the obsolete DF3-8S-2R26(05). Both connectors share identical mechanical specifications, pitch, position count, and housing configuration, ensuring direct physical compatibility within DF3 series applications.

The primary functional difference is the cable termination method: the original part uses IDC termination, while the substitute uses crimp termination. This distinction requires assessment of the existing cable assembly and termination infrastructure in the application.

The DF3-8S-2C holds superior regulatory status with ROHS3 compliance compared to the original RoHS compliance designation, meeting current environmental standards. Both parts maintain MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can DF3-8S-2C directly replace DF3-8S-2R26(05) in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for the DF3 series receptacle housing. The critical consideration is cable termination compatibility. The original part accommodates IDC-terminated cables, while the substitute requires crimp-terminated contacts. Existing IDC cable assemblies cannot be directly mated to the DF3-8S-2C housing without reconfiguration.

Q: What is the significance of the termination method difference?

A: IDC (Insulation Displacement Contact) termination pierces the wire insulation during insertion, while crimp termination requires pre-assembled contacts. The DF3-8S-2C housing is supplied without contacts, requiring separate procurement and assembly of crimp-style contacts compatible with the DF3 series.

Q: Are there any compliance or certification differences?

A: The DF3-8S-2C meets ROHS3 compliance, which supersedes the RoHS compliance of the original part. Both maintain identical MSL 1 ratings. No additional certifications or restrictions apply to either part.

Q: What is the inventory status for these parts?

A: The DF3-8S-2R26(05) is obsolete with limited stock availability (703 pcs). The DF3-8S-2C is active production with substantial inventory (500,300 pcs), ensuring reliable long-term sourcing for new designs and replacements.

Q: Are there any operating temperature or environmental differences?

A: The DF3-8S-2C specifies an operating temperature range of -55°C to 105°C. No operating temperature specification is provided for the original part. Both maintain unlimited moisture sensitivity tolerance at MSL 1.
