Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-15S-2R28(85) is based on the following critical parameters:

• Number of Positions: 15-position configuration is the primary functional requirement
• Connector Category: Rectangular connector classification
• Contact Configuration: Receptacle type with female socket contacts
• Cable Termination Method: IDC (Insulation Displacement Contact) termination
• Wire Gauge Compatibility: 26-28 AWG wire gauge range
• Pitch Specification: 0.079" (2.00mm) pitch for contact spacing
• Contact Finish: Tin plating for corrosion resistance and solderability

The substitute part 1-173977-5 meets these functional equivalence criteria through matching position count, termination method, wire gauge range, and pitch specification.

Engineering Selection Recommendations

The 1-173977-5 rectangular connector from TE Connectivity AMP Connectors serves as the primary substitute for the obsolete DF3-15S-2R28(85). This selection is based on:

• Active Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status satisfy current environmental and regulatory requirements
• Functional Equivalence: Matching 15-position configuration, IDC termination method, and 26-28 AWG wire gauge range provide direct functional compatibility
• Moisture Sensitivity: MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling

Selection of this substitute eliminates obsolescence risk while maintaining electrical and mechanical compatibility with existing applications designed for 15-position IDC rectangular connectors.

Frequently Asked Questions (FAQ)

Q: Why is the DF3-15S-2R28(85) no longer available? A: The DF3-15S-2R28(85) carries an obsolete product status, indicating that Hirose Electric Co Ltd has discontinued manufacturing. Substitute parts must be identified to support ongoing applications and maintenance requirements.

Q: What makes the 1-173977-5 a suitable substitute? A: The 1-173977-5 matches the critical functional parameters of the original part: 15-position configuration, IDC cable termination, 26-28 AWG wire gauge compatibility, and 0.079" (2.00mm) pitch specification. Both are rectangular receptacle connectors designed for identical wire gauge ranges.

Q: Are there any compliance differences between the original and substitute? A: The substitute part 1-173977-5 carries ROHS3 compliance and REACH unaffected status, meeting current environmental regulations. The original part specifications do not include these compliance certifications.

Q: What is the significance of the IDC termination method? A: IDC (Insulation Displacement Contact) termination allows direct connection of discrete wire without stripping insulation. This method is standard for both the original and substitute parts, ensuring compatibility with existing cable assemblies and termination equipment.

Q: Does the MSL rating affect substitution? A: The substitute part carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. This provides superior handling flexibility compared to the original part's not applicable rating and is suitable for all standard storage and operational environments.

Q: What packaging considerations apply to the substitute? A: The 1-173977-5 is supplied in bulk packaging. Verify that bulk packaging meets your procurement and inventory management requirements before finalizing the substitution decision.
