Key Parameters

Substitute Part Grouping Explanation

Substitution for the N10250-52B3PC is determined by the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 50 positions and 2-row layout
• Mounting Configuration: Panel mount, through-hole, right-angle orientation
• Termination Method: Solder termination
• Connector Style: Outer shroud contacts with board lock functionality
• Electrical & Environmental Compliance: RoHS compliance and MSL rating

The substitute parts listed below maintain these core functional parameters while offering active product status and improved availability. Substitutes are grouped by manufacturer and series, each meeting the electrical and mechanical requirements for direct replacement in legacy systems.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5178238-7 (TE Connectivity CHAMP .050 II)

This substitute provides the closest functional match to the N10250-52B3PC. It maintains receptacle configuration, 50-position layout, panel mount through-hole right-angle orientation, and solder termination. The outer shroud contact style with board lock functionality aligns with the original design. ROHS3 compliance exceeds the original RoHS requirement, and active product status ensures long-term availability with 200,200 units in stock.

Secondary Substitute: 5787083-5 (TE Connectivity AMPLIMITE .050 III)

This D-Type receptacle offers active product status and ROHS3 compliance. It maintains the 50-position, 2-row configuration with solder termination and board lock, shielded features. The board edge mounting option provides flexibility for applications requiring alternative mounting configurations. Operating temperature range extends to 105°C, supporting higher thermal environments.

Alternative Substitute: DX10G1M-50SE(50) (Hirose DXM Series)

This miniature high-density receptacle from Hirose provides an active alternative with panel mount through-hole right-angle configuration. It maintains 50-position layout, solder termination, and board lock functionality. ROHS3 compliance and 1,141 units in stock provide immediate availability. The miniature HD form factor may require mechanical verification for panel cutout compatibility.

Connector Type Consideration: 5174726-4 (TE Connectivity AMPLIMITE .050 II)

This D-Type plug with female sockets represents a different connector type (plug versus receptacle). While it maintains 50-position, 2-row configuration and solder termination, it is suitable only for applications where the mating interface has been redesigned to accept a plug configuration. This substitute requires system-level compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace N10250-52B3PC with 5178238-7?

A: Yes. Both are 50-position receptacles with panel mount through-hole right-angle solder termination, outer shroud contacts, and board lock functionality. The 5178238-7 is an active product with superior compliance status (ROHS3) and significantly higher inventory availability.

Q: What is the difference between the TE Connectivity CHAMP and AMPLIMITE series substitutes?

A: The CHAMP .050 II (5178238-7) is optimized for panel mount applications with board-side flange mounting. The AMPLIMITE .050 III (5787083-5) offers board edge mounting flexibility and extended operating temperature range to 105°C. Both maintain core 50-position receptacle functionality.

Q: Is the Hirose DX10G1M-50SE(50) a direct replacement?

A: The Hirose connector maintains the same 50-position receptacle configuration, panel mount through-hole right-angle solder termination, and board lock features. However, as a miniature high-density design, mechanical verification of panel cutout dimensions is required before implementation.

Q: Why is 5174726-4 listed as a substitute if it is a plug, not a receptacle?

A: The 5174726-4 is included as a substitute option only for applications where the mating connector interface can be redesigned or has already been modified to accept a plug configuration. This requires system-level compatibility assessment and is not a direct drop-in replacement.

Q: Are all substitutes RoHS compliant?

A: Yes. The original N10250-52B3PC is RoHS Compliant. All listed substitutes meet or exceed RoHS requirements, with TE Connectivity and Hirose options providing ROHS3 compliance, which represents the current regulatory standard.

Q: What is the MSL rating for these connectors?

A: All connectors, including the original and all substitutes, carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute offers the best long-term availability?

A: The 5178238-7 (TE Connectivity CHAMP .050 II) offers the highest inventory level at 200,200 units in stock, combined with active product status, ensuring sustained availability for ongoing production and repair requirements.
