Substitute Part Grouping Explanation

Substitution of the obsolete 5175677-7 is based on electrical and mechanical parameter equivalence within the CHAMP .050 II connector series. The substitute part 2-5175677-7 maintains identical core specifications: 50-position plug configuration, 2-row arrangement, free hanging in-line mounting, IDC termination, center strip contact design, and gold contact finish. Both parts share the same base product number (5175677) and series designation, confirming functional interchangeability.

The primary distinction between the main part and its substitute is product status and packaging configuration. The substitute part 2-5175677-7 is active in production, whereas 5175677-7 is obsolete. Contact finish thickness differs between the two parts (11.8µin versus 30.0µin), reflecting manufacturing variations within acceptable gold plating specifications for this connector category.

Key parameters determining substitution eligibility:

• Connector type and position count (50-position plug)
• Row configuration (2 rows)
• Mounting method (free hanging in-line)
• Termination technology (IDC)
• Contact style (center strip)
• Series compatibility (CHAMP .050 II)
• Compliance certifications (ROHS3, MSL 1)

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-5175677-7 is the direct equivalent for the obsolete 5175677-7. Selection of the substitute is based on the following engineering criteria:

Product Status: The main part 5175677-7 is obsolete and no longer in active production. The substitute 2-5175677-7 maintains active production status, ensuring long-term availability and supply chain continuity.

Electrical and Mechanical Compatibility: Both parts are functionally identical across all critical parameters: 50-position configuration, 2-row layout, IDC termination, center strip contact design, and free hanging in-line mounting. The connector series designation (CHAMP .050 II) is identical, confirming mechanical and electrical interchangeability.

Compliance and Certifications: Both parts meet ROHS3 compliance requirements and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent environmental performance and handling requirements.

Contact Finish Specification: The substitute part features increased gold plating thickness (30.0µin versus 11.8µin), which provides enhanced durability and contact reliability without compromising electrical performance or mechanical fit.

Packaging Configuration: The substitute is supplied in bulk packaging, suitable for production environments requiring standard component handling and inventory management.

Frequently Asked Questions (FAQ)

Q: Are 5175677-7 and 2-5175677-7 electrically interchangeable?

A: Yes. Both parts are 50-position plug connectors with identical electrical specifications, including IDC termination, center strip contact configuration, and gold contact finish. They are functionally equivalent for circuit integration.

Q: What is the significance of the different contact finish thicknesses?

A: The substitute part 2-5175677-7 features 30.0µin (0.76µm) gold plating compared to 11.8µin (0.30µm) on the main part. Both thicknesses meet industry standards for D-Sub connector applications. The increased thickness on the substitute provides extended contact life and improved wear resistance in high-cycle mating applications.

Q: Can I use 2-5175677-7 as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical mechanical dimensions, mounting configuration, and electrical characteristics. No design modifications are required for integration into systems currently using 5175677-7.

Q: Why is the main part obsolete?

A: Product obsolescence is determined by manufacturer production decisions. The substitute 2-5175677-7 remains in active production and serves the same functional requirements.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and carry identical MSL 1 (Unlimited) ratings. Environmental and regulatory compliance requirements are equivalent.

Q: What packaging options are available?

A: The main part 5175677-7 packaging is not specified in available documentation. The substitute 2-5175677-7 is supplied in bulk packaging, standard for production component procurement.

Q: How do I verify compatibility with my existing connector receptacles?

A: Both parts belong to the CHAMP .050 II series with identical 50-position, 2-row plug configuration and center strip contact design. Mechanical and electrical compatibility with corresponding receptacles is assured.
