Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1705950-5 are identified based on electrical and mechanical parameter equivalence within the modular connector category. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Connector type (Jack)
• Number of positions and contacts (6p4c / RJ11, RJ14)
• Orientation (90° Angle Right)
• Mounting type (Through Hole)
• Termination method (Solder)
• Shielding configuration (Unshielded)
• Performance rating (Cat3)
• Contact material and finish (Phosphor Bronze with Gold plating)
• Housing material (PBT)
• Mechanical features (Board Lock, Down tab direction)

Parts meeting all these parameters are electrically and mechanically interchangeable and can be substituted without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The 1705950-2 is a direct functional equivalent to the 1705950-5 and serves as the primary substitute for this obsolete connector. Both parts share identical electrical and mechanical specifications, including connector configuration, contact materials, termination method, and performance ratings.

Key Selection Factors:

Product Status: The 1705950-5 is classified as obsolete, while the 1705950-2 maintains active product status. This distinction ensures long-term availability and continued manufacturer support for the 1705950-2.

Compliance and Certifications: Both parts maintain ROHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040), confirming equivalent environmental and export compliance profiles.

Packaging Consideration: The 1705950-2 is supplied in Cut Tape (CT) packaging, which differs from the unspecified packaging of the 1705950-5. This packaging format is standard for modular connector distribution and does not affect electrical or mechanical performance.

Supply Availability: The 1705950-2 demonstrates significantly higher inventory levels (2280 pieces) compared to the 1705950-5 (794 pieces), supporting reliable procurement for new designs and production requirements.

For applications currently utilizing the 1705950-5, direct substitution with the 1705950-2 requires no circuit redesign, PCB layout modification, or performance re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can the 1705950-2 be used as a direct replacement for the 1705950-5 without PCB modifications?

A: Yes. The 1705950-2 is electrically and mechanically identical to the 1705950-5 across all critical parameters including connector type, pin configuration, orientation, mounting type, and termination method. No PCB layout changes are required.

Q: What is the difference between the 1705950-5 and 1705950-2?

A: The primary differences are product status and packaging. The 1705950-5 is obsolete, while the 1705950-2 is active. The 1705950-2 is supplied in Cut Tape (CT) packaging. All electrical and mechanical specifications are identical.
