Substitute Part Grouping Explanation

Substitution of the obsolete 175474-6 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 5175474-6 maintains identical specifications for connector position count, row configuration, mounting orientation, termination method, contact finish, and moisture sensitivity classification. Both parts operate within the CHAMP .050 I series and provide board-to-board receptacle functionality with solder attachment.

The primary distinction between the main part and its substitute is the connector type designation: the 175474-6 is classified as standard board-to-board, while the 5175474-6 is designated as high-density board-to-board. This classification difference reflects design evolution within the same series while preserving mechanical and electrical compatibility. The substitute part carries active product status and RoHS3 compliance, addressing regulatory requirements for current manufacturing environments.

Substitution eligibility is determined by the following parameters:

• 50-position receptacle configuration
• 2-row arrangement
• Through-hole, right-angle mounting
• Solder termination
• Gold contact finish at 8.00µin thickness
• Board lock feature
• Outer shroud contact style
• MSL 1 rating

Engineering Selection Recommendations

The 5175474-6 serves as the direct functional equivalent for the obsolete 175474-6. Selection of the substitute part is based on the following engineering considerations:

Product Status: The 175474-6 is classified as obsolete, creating supply chain risk for ongoing production and field service requirements. The 5175474-6 maintains active product status, ensuring continued availability and manufacturer support.

Regulatory Compliance: The 175474-6 is RoHS non-compliant, which restricts its use in applications subject to RoHS3 regulations. The 5175474-6 is RoHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution in regulated markets.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all critical parameters including position count, row configuration, mounting type, termination method, contact finish, and moisture sensitivity rating. The high-density designation of the substitute part reflects design optimization within the same series without altering functional compatibility.

Inventory Availability: The 5175474-6 is available in active inventory (763 pieces), providing immediate procurement capability compared to the obsolete status of the main part.

Frequently Asked Questions (FAQ)

Q: Are the 175474-6 and 5175474-6 mechanically interchangeable?

A: Yes. Both connectors share identical mounting specifications (through-hole, right-angle), position count (50), row configuration (2), and board lock features. They are designed for direct substitution in board-to-board applications.

Q: What is the difference between "board-to-board" and "board-to-board, high-density" designations?

A: The high-density designation indicates design optimization within the CHAMP .050 I series. Both configurations maintain the same electrical and mechanical parameters specified for this connector category. The designation reflects product line evolution rather than functional incompatibility.

Q: Can the 5175474-6 be used in applications originally designed for the 175474-6?

A: Yes. The substitute part maintains all critical electrical and mechanical specifications required for functional equivalence. The primary advantage is active product status and RoHS3 compliance.

Q: What is the significance of the RoHS3 compliance difference?

A: RoHS3 compliance is required for components used in regulated markets and applications subject to environmental and hazardous substance restrictions. The 5175474-6 meets these requirements, while the 175474-6 does not. For new designs and production environments with regulatory requirements, the 5175474-6 is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The 5175474-6 is supplied in tray packaging. The main part packaging specification is not provided. Packaging differences do not affect functional compatibility but may influence handling, storage, and logistics procedures.

Q: Do both parts have the same contact finish specifications?

A: Yes. Both connectors feature gold-plated contacts with 8.00µin (0.203µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: What is the Moisture Sensitivity Level (MSL) rating for these connectors?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
