Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5917738-7 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Receptacle
• Position count: 50
• Row configuration: 2 rows
• Mounting configuration: Panel mount, through-hole, right-angle orientation
• Termination method: Solder
• Connector style: Outer shroud contacts
• Contact finish: Gold plating

Secondary Compatibility Factors:

• Flange feature housing specification (M2.6 or 4-40 thread)
• Presence of board lock feature
• Shielding configuration
• RoHS compliance status
• Moisture sensitivity level

All identified substitute parts maintain the primary matching criteria. Variations exist in flange specifications, latchblock presence, and shielding features. These variations are documented in the parameter comparison table to enable informed selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are manufactured by 3M and maintain active product status, providing long-term availability and supply chain stability compared to the obsolete TE Connectivity 5917738-7.

Compliance Alignment: All substitute parts achieve RoHS compliance and maintain EAR99 export classification and identical HTSUS coding. Moisture sensitivity level remains constant at MSL 1 (Unlimited) across all options.

Flange Feature Considerations:

• M2.6 Housing/Shell Configuration: N10250-52G3PC, 10250-55G3PC, N10250-52B2PC maintain the original M2.6 flange specification, providing direct mechanical compatibility with existing panel mount designs.
• 4-40 Housing/Shell Configuration with Latchblocks: 10250-55H3PC, N10250-5242PC, N10250-52E2PC feature 4-40 thread specification and latchblock elements, requiring mechanical design verification for panel integration.

Feature Differentiation:

• Board Lock + Shielded Configuration: N10250-52G3PC, 10250-55G3PC, N10250-52B2PC, N10250-52E2PC provide both board lock and shielding features, matching the functional intent of the original part.
• Shielded Only Configuration: N10250-5242PC provides shielding without board lock feature, suitable for applications where board lock is not required.

Contact Finish Thickness: All 3M substitute parts feature 30.0µin (0.76µm) gold plating, exceeding the original 3.94µin (0.10µm) specification, providing enhanced contact durability and corrosion resistance.

Packaging and Inventory: Substitute parts are available in multiple packaging formats (Bulk, Box, Tray) with substantial inventory levels, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M substitute parts directly replace the TE Connectivity 5917738-7 in existing designs?

A: Direct replacement depends on flange feature compatibility. Parts with M2.6 housing specification (N10250-52G3PC, 10250-55G3PC, N10250-52B2PC) provide mechanical compatibility with existing M2.6 panel mount designs. Parts with 4-40 housing specification require panel design modification.

Q: What is the significance of the contact finish thickness difference?

A: The 3M substitute parts feature 30.0µin (0.76µm) gold plating compared to the original 3.94µin (0.10µm). This increased thickness provides enhanced contact durability, improved corrosion resistance, and extended connector lifecycle. This represents a performance improvement over the original specification.

Q: Which substitute part most closely matches the original TE Connectivity 5917738-7?

A: N10250-52G3PC and N10250-52B2PC provide the closest functional match, maintaining M2.6 flange specification, board lock feature, and shielding configuration. Both parts are active products with established supply availability.

Q: Are all substitute parts RoHS compliant?

A: All identified substitute parts achieve RoHS compliance status. The original TE Connectivity part maintains ROHS3 compliance, while all 3M alternatives maintain RoHS compliance, satisfying regulatory requirements for both legacy and current design standards.

Q: What packaging options are available for the substitute parts?

A: Substitute parts are available in three packaging configurations: Bulk (N10250-52G3PC), Box (10250-55G3PC, N10250-5242PC, N10250-52B2PC, N10250-52E2PC), and Tray (10250-55H3PC). Selection depends on procurement volume and inventory management requirements.

Q: Do all substitute parts include board lock features?

A: Board lock features are present in N10250-52G3PC, 10250-55G3PC, N10250-52B2PC, and N10250-52E2PC. The N10250-5242PC variant provides shielding without board lock functionality. Design requirements determine whether board lock is necessary for specific applications.

Q: What is the difference between M2.6 and 4-40 flange specifications?

A: M2.6 represents metric thread specification (2.6mm diameter), while 4-40 represents unified thread specification (0.112 inch diameter, 40 threads per inch). Panel mount hole patterns and fastening hardware differ between these specifications. Existing designs using M2.6 require mechanical modification to accommodate 4-40 specification.

Q: Are the substitute parts suitable for high-reliability applications?

A: All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating and RoHS compliance, supporting high-reliability application requirements. The enhanced gold plating thickness on 3M parts provides additional durability for demanding environments.
