170-050-172-020 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The 170-050-172-020 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 compatible substitute parts essential for ongoing system maintenance and new design implementations. The housing serves as the mechanical and electrical interface for D-Sub signal connectors in free-hanging, in-line mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 170-050-172-020 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 170-050-173L020 maintains identical values across all these core parameters, establishing direct functional compatibility. Variations in shell finish material, operating temperature range, and product status do not affect mechanical or electrical interchangeability for connector housing applications.

Engineering Selection Recommendations

The 170-050-173L020 serves as the direct substitute for the obsolete 170-050-172-020. Selection of the substitute part is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance satisfies current regulatory requirements for new designs and manufacturing processes
• Extended operating temperature range (-50°C ~ 125°C versus -50°C ~ 100°C) provides broader environmental tolerance
• 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 requiring RoHS non-compliant components or tin/zinc plating specifically, the 170-050-172-020 remains available in existing inventory; however, the 170-050-173L020 is the recommended selection for new implementations and long-term system support.

Frequently Asked Questions (FAQ)

Q: Can the 170-050-173L020 directly replace the 170-050-172-020 in existing assemblies?

A: Yes. Both parts maintain identical connector style, type, position count, row configuration, shell size, contact type, mounting type, and flange specifications. Direct mechanical and electrical interchangeability is established.

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

A: Both finishes provide corrosion protection for steel connector housings. Nickel plating offers equivalent performance for standard signal connector applications. Selection between finishes depends on specific environmental exposure requirements not provided in this reference.

Q: Why is the 170-050-172-020 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 170-050-173L020 represents the current active equivalent from the same manufacturer and series.

Q: Does the extended operating temperature range of the 170-050-173L020 affect compatibility?

A: No. The extended range (-50°C ~ 125°C) is a superset of the original specification (-50°C ~ 100°C). Applications operating within the original temperature limits remain fully compatible.

Q: What is the significance of ROHS3 compliance on the 170-050-173L020?

A: ROHS3 compliance indicates the part meets current Restriction of Hazardous Substances regulations. This is required for many commercial and industrial applications and new product designs.

Q: Are contacts included with either housing part?

A: No. Both the 170-050-172-020 and 170-050-173L020 are housings only. Male contacts must be sourced separately and are not included.

Q: What packaging is available for the substitute part?

A: The 170-050-173L020 is supplied in tray packaging. Original packaging specifications for the 170-050-172-020 are not provided in this reference.
