DDM50PC D-Sub 50 Position Plug Connector Equivalent & Substitute Parts

Part Overview

The DDM50PC is a 50 position D-Sub plug connector manufactured by ITT Cannon, LLC, designed for panel mount, through-hole, right-angle solder termination applications. This connector features male pins with a 3-row configuration in shell size 5 (DD, D) and is rated for 7.5A continuous current operation across an operating temperature range of -55°C to 125°C. The connector maintains active product status with 800 units currently in stock.

Equivalent and substitute parts are identified when design requirements, application constraints, or supply chain considerations necessitate alternative sourcing while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DDM50PC are identified based on strict equivalence of the following critical parameters:

• Connector type: D-Sub plug with male pins
• Position count: 50 positions
• Row configuration: 3 rows
• Shell size: 5 (DD, D)
• Mounting configuration: Panel mount, through-hole, right-angle
• Termination method: Solder
• Flange feature: Unthreaded housing/shell
• Contact type: Signal
• Contact form: Machined
• Material flammability: UL94 V-0

The substitute parts 174-E50-113R001 and 174-E50-113R141, both manufactured by NorComp Inc., satisfy these core functional and mechanical requirements. Variations in secondary parameters such as shell finish material, current rating, operating temperature range, and regulatory compliance status are documented in the parameter comparison table to enable informed selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection between the DDM50PC and its substitute parts should be based on the following criteria:

DDM50PC (ITT Cannon, LLC): Select this part when the application requires the extended operating temperature range of -55°C to 125°C, the higher current rating of 7.5A, or when RoHS non-compliance is acceptable. This connector is suitable for legacy systems or applications where the yellow chromate plated zinc finish is specified.

174-E50-113R001 (NorComp Inc.): This substitute is appropriate for applications requiring ROHS3 compliance, operating within the -50°C to 100°C temperature range, and where the 5A current rating is sufficient. The unthreaded housing/shell configuration matches the DDM50PC, and grounding indents provide additional shielding capability. This part is suitable for modern commercial and industrial applications with RoHS requirements.

174-E50-113R141 (NorComp Inc.): This substitute offers the same ROHS3 compliance and temperature/current specifications as 174-E50-113R001, with the addition of a female screwlock (4-40) mating side connector and mounting brackets. Select this variant when mechanical retention via screwlock and integrated mounting brackets are required for the application.

All three parts maintain active product status and UL94 V-0 flammability certification, ensuring continued availability and compliance with fire safety standards.

Frequently Asked Questions (FAQ)

Q: Can 174-E50-113R001 or 174-E50-113R141 be used as direct replacements for DDM50PC in existing designs?

A: Both NorComp parts are mechanically and electrically compatible with DDM50PC for applications operating within -50°C to 100°C and requiring 5A or less current. The 50-position, 3-row, shell size 5 (DD, D) configuration, solder termination, and right-angle panel mount design are identical. However, verify that your application does not require the extended -55°C to 125°C temperature range or 7.5A current rating of the DDM50PC.

Q: What is the difference between 174-E50-113R001 and 174-E50-113R141?

A: Both parts share identical electrical and mechanical specifications. The primary difference is the flange feature: 174-E50-113R001 has an unthreaded housing/shell, while 174-E50-113R141 includes a female screwlock (4-40) mating side connector and mounting brackets. Select 174-E50-113R141 when mechanical retention and integrated mounting hardware are required.

Q: Are there RoHS compliance implications when substituting DDM50PC with NorComp alternatives?

A: Yes. The DDM50PC is RoHS non-compliant, while both 174-E50-113R001 and 174-E50-113R141 are ROHS3 compliant. If your application or end-market requires RoHS compliance, the NorComp substitutes are the appropriate choice. If RoHS compliance is not a requirement, the DDM50PC remains a valid option.

Q: What are the packaging differences between these parts?

A: The DDM50PC is supplied in standard packaging (not specified), while both NorComp substitutes are packaged in trays. Verify tray packaging compatibility with your assembly and handling processes.

Q: How do the shell finish materials compare?

A: The DDM50PC features a yellow chromate plated zinc finish, while the NorComp substitutes use nickel plating. Both finishes provide corrosion resistance; however, the nickel plating of the NorComp parts may offer superior performance in certain corrosive environments. Verify finish compatibility with your application's environmental requirements.

Q: Can I use these parts interchangeably in the same PCB assembly?

A: Yes, provided your application operates within the overlapping specifications: -50°C to 100°C operating temperature, 5A maximum current, and does not require the extended temperature range or higher current rating of the DDM50PC. All three parts use identical solder termination and right-angle panel mount configurations, making them mechanically interchangeable at the PCB level.
