TE Connectivity AMP Connectors 5178238-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5178238-7 is a 50 Position Receptacle Connector with right-angle solder termination, designed for panel mount through-hole applications. This connector belongs to the CHAMP .050 II series and features outer shroud contacts with board lock functionality. The part is currently active in production with 200,200 pieces in stock inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part is unavailable, discontinued, or when design flexibility permits alternative qualified components within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5178238-7 is determined by strict alignment of the following core parameters:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 50
• Number of Rows: 2
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Termination Method: Solder
• Connector Style: Outer Shroud Contacts
• Contact Finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified—3M N10250-52B2PC and 3M N10250-52E2PC—satisfy all critical matching parameters. Both parts are 50-position receptacle connectors with right-angle solder termination, panel mount through-hole configuration, and gold-plated contacts. Both maintain MSL 1 rating and RoHS compliance. Differences in flange feature design (Board Side M2.6 versus Housing/Shell variants) and contact finish thickness represent acceptable variations within the D-Sub receptacle connector category that do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5178238-7 remains the primary specification when original equipment design documentation references this part number. The connector is active in production with substantial inventory availability (200,200 pieces), ROHS3 compliant, and carries EAR99 export classification.

3M N10250-52E2PC serves as the preferred substitute when design flexibility permits. This part maintains full electrical and mechanical compatibility with identical position count, row configuration, and solder termination. The connector features enhanced shielding and latchblock provisions, with active production status and 3,483 pieces in stock. RoHS compliance and EAR99 classification are confirmed. The Housing/Shell flange with 4-40 mounting differs from the original board-side M2.6 design but accommodates standard panel mounting applications.

3M N10250-52B2PC functions as an alternative substitute with identical core specifications. This variant employs Housing/Shell M2.6 flange mounting and includes shielding features. Inventory availability is lower (999 pieces) compared to the N10250-52E2PC variant. RoHS compliance and EAR99 classification apply.

All three connectors maintain MSL 1 rating, indicating unlimited shelf life under standard storage conditions. Selection between substitutes depends on specific flange mounting requirements and panel design constraints.

Frequently Asked Questions (FAQ)

Q: Can the 3M N10250-52E2PC directly replace the TE Connectivity 5178238-7 in existing designs?

A: The N10250-52E2PC satisfies all critical electrical and mechanical parameters: 50-position receptacle configuration, right-angle solder termination, panel mount through-hole mounting, and gold-plated contacts. The primary design consideration is the flange feature difference (Housing/Shell 4-40 versus Board Side M2.6). Panel mounting hole patterns must be verified for compatibility with the specific flange design.

Q: What is the difference between the two 3M substitute options?

A: Both 3M N10250-52B2PC and N10250-52E2PC are 50-position receptacle connectors with identical electrical specifications. The N10250-52B2PC uses Housing/Shell M2.6 flange mounting, while the N10250-52E2PC uses Housing/Shell 4-40 flange mounting and includes latchblock provisions. Selection depends on panel mounting hole specifications and mechanical retention requirements.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: All three connectors carry EAR99 export classification and HTSUS code 8536.69.4040. The TE Connectivity 5178238-7 is ROHS3 compliant, while both 3M substitutes are RoHS compliant. All parts maintain MSL 1 rating. No regulatory barriers exist for substitution within domestic applications.

Q: How do contact finish thickness differences affect performance?

A: The TE Connectivity 5178238-7 specifies 11.8µin (0.30µm) gold contact finish, while both 3M substitutes provide 30.0µin (0.76µm) finish thickness. The thicker gold plating on 3M connectors provides enhanced contact durability and corrosion resistance. This represents an improvement over the original specification and does not create compatibility issues.

Q: What inventory considerations apply to substitute selection?

A: The TE Connectivity 5178238-7 maintains the highest inventory level at 200,200 pieces. The 3M N10250-52E2PC has 3,483 pieces available, while the N10250-52B2PC has 999 pieces. For applications requiring immediate availability or high-volume procurement, the original TE Connectivity part offers the most reliable supply position.

Q: Do the shielding features on 3M substitutes affect mechanical fit?

A: Both 3M substitutes include shielding features not present on the original TE Connectivity 5178238-7. Shielding is integrated into the connector housing and does not affect solder pad layout or through-hole positioning. Panel cutout dimensions and mounting hole patterns remain the primary mechanical compatibility factors.
