TE Connectivity 205210-2 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 205210-2 is a D-Sub connector housing plug designed for 37-position male contact applications. This component functions as the shell assembly for AMPLIMITE HDP-20 series D-Sub connectors, providing the mechanical structure and contact retention for signal transmission in inline, free-hanging configurations.

The 205210-2 is classified as obsolete product status. Identification of equivalent and substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where this connector housing is specified or currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 205210-2 is determined by strict equivalence across the following parameters:

• Connector Style: D-Sub (required match)
• Connector Type: Plug for Male Contacts (required match)
• Number of Positions: 37 (required match)
• Number of Rows: 2 (required match)
• Shell Size, Connector Layout: 4 (DC, C) (required match)
• Mounting Type: Free Hanging (In-Line) (required match)
• Flange Feature: Housing/Shell (Unthreaded) (required match)
• Dielectric Material: Polyamide (PA), Nylon, Glass Filled (required match)
• Series: AMPLIMITE HDP-20 (required match)

The substitute part 205210-7 meets all required parameters for direct substitution. Variations in shell material finish and product status do not affect mechanical or electrical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The 205210-7 is the direct substitute for the obsolete 205210-2. Both parts are manufactured by TE Connectivity within the AMPLIMITE HDP-20 series and share identical mechanical and electrical specifications across all critical parameters.

Product Status Consideration: The 205210-2 is obsolete, while the 205210-7 is active production. For new designs and ongoing procurement, the 205210-7 is the appropriate selection.

Compliance Consideration: The 205210-7 is ROHS3 compliant, whereas the 205210-2 is RoHS non-compliant. Applications subject to RoHS requirements must use the 205210-7. The 205210-2 remains suitable for legacy systems and applications without RoHS mandates.

Shell Finish Variation: The 205210-2 features tin-lead plating; the 205210-7 features tin plating. Both finishes provide equivalent corrosion resistance and electrical performance within the D-Sub connector application class. This variation does not affect mechanical fit or electrical compatibility.

Inventory and Availability: The 205210-7 is available in higher inventory quantity (1896 pcs) compared to the 205210-2 (1134 pcs), supporting supply chain continuity for active programs.

Frequently Asked Questions (FAQ)

Q: Can the 205210-7 be used as a direct replacement for the 205210-2 in existing assemblies?

A: Yes. The 205210-7 is mechanically and electrically equivalent to the 205210-2 across all specified parameters. Both housings accept the same male contact pins, mate with identical receptacle housings, and maintain the same dimensional envelope and mounting configuration.

Q: What is the difference between tin-lead plating and tin plating on the shell?

A: The 205210-2 uses tin-lead plating; the 205210-7 uses tin plating. Both provide corrosion protection and electrical conductivity suitable for D-Sub connector applications. The tin plating on the 205210-7 reflects current manufacturing standards and RoHS compliance requirements.

Q: Why is the 205210-2 marked as obsolete?

A: The 205210-2 is obsolete due to its RoHS non-compliant status and the availability of the RoHS3-compliant 205210-7 as the current production equivalent. TE Connectivity has transitioned to the 205210-7 for ongoing manufacturing and support.

Q: Are there any compatibility issues when mixing 205210-2 and 205210-7 housings in the same system?

A: No compatibility issues exist. Both housings are mechanically and electrically interchangeable within the AMPLIMITE HDP-20 series. They can be used together in multi-connector applications without functional degradation.

Q: What packaging is available for each part?

A: The 205210-2 is available in standard packaging (not specified). The 205210-7 is available in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Do these housings include contacts?

A: No. Both the 205210-2 and 205210-7 are housing assemblies only. Male contacts must be ordered separately and inserted into the housing according to TE Connectivity assembly specifications.

Q: Which part should be specified for new designs?

A: The 205210-7 should be specified for all new designs. It is the active production part, offers RoHS3 compliance, and ensures long-term supply chain support and availability.
