170-050-172-010 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The 170-050-172-010 is a D-Sub connector housing plug manufactured by NorComp Inc., designed for 50-position male contact applications. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The housing serves as the mechanical and electrical interface for D-Sub connector assemblies in free-hanging, in-line mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 170-050-172-010 is determined by the following critical parameters:

• Connector Style: D-Sub
• Connector Type: Plug for Male Contacts
• Number of Positions: 50
• Number of Rows: 3
• Shell Size, Connector Layout: 5 (DD, D)
• Contact Type: Signal
• Mounting Type: Free Hanging (In-Line)
• Flange Feature: Cable Side (4-40)

The substitute part 170-050-173L010 maintains identical values across all these parameters, establishing direct functional compatibility. Variations in shell finish material, operating temperature range, dielectric material specification, and product status do not affect mechanical or electrical interchangeability for connector housing applications.

Engineering Selection Recommendations

The 170-050-173L010 serves as the direct substitute for the obsolete 170-050-172-010. Selection of the substitute part is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance addresses regulatory requirements for new designs and manufacturing environments where RoHS compliance is mandated
• Extended operating temperature range (-50°C ~ 125°C versus -50°C ~ 100°C) provides broader thermal operational capability
• Nickel plating finish offers equivalent corrosion resistance to tin/zinc plating for connector housing applications
• Identical mechanical and electrical specifications guarantee direct form, fit, and function compatibility

For applications where RoHS compliance is not required and the original tin/zinc plated finish is specifically mandated, the 170-050-172-010 remains functionally equivalent to the substitute, subject to availability constraints due to obsolete status.

Frequently Asked Questions (FAQ)

Q: Can the 170-050-173L010 directly replace the 170-050-172-010 in existing assemblies?

A: Yes. Both parts share identical connector style, type, position count, row configuration, shell size, contact type, mounting type, and flange specifications. The housing plug is mechanically and electrically interchangeable.

Q: What is the difference between tin/zinc plating and nickel plating on the connector housing?

A: Both finishes provide corrosion protection for steel shells. Nickel plating offers equivalent performance for standard D-Sub connector applications. Selection between finishes depends on specific environmental exposure requirements and application specifications.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The substitute part's extended range (-50°C ~ 125°C) encompasses the original part's range (-50°C ~ 100°C). This represents an enhancement, not a limitation.

Q: Why is the 170-050-172-010 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 170-050-173L010 is the active equivalent, ensuring continued availability for new designs and replacement applications.

Q: What does ROHS3 compliance mean for connector selection?

A: ROHS3 compliance certifies the part meets Restriction of Hazardous Substances regulations. For applications subject to RoHS requirements, the 170-050-173L010 is the appropriate selection.

Q: Are contacts included with either housing part?

A: No. Both the main part and substitute are housings only. Male contacts must be sourced separately and are not included with the connector housing.

Q: What packaging is available for the substitute part?

A: The 170-050-173L010 is supplied in tray packaging, suitable for automated assembly and component handling processes.
