TE Connectivity 205211-1 D-Sub Receptacle Housing 50 Position Equivalent & Substitute Parts

Part Overview

The TE Connectivity 205211-1 is a D-Sub receptacle housing designed for female contacts in a 50-position configuration. This connector belongs to the AMPLIMITE HDP-20 series and features a 3-row layout with shell size 5 (DD, D) designation. The part is classified as obsolete, which necessitates identification of active equivalent components for ongoing procurement and system maintenance. Substitute parts maintain functional compatibility through identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 205211-1 with the active equivalent 1658640-2 is based on strict parameter matching across all critical electrical and mechanical specifications. Both parts share identical configurations in connector style, type, position count, row arrangement, shell size, contact type, mounting method, flange design, shell material and finish, dielectric composition, and color. The substitute part maintains the same AMPLIMITE HDP-20 series designation and operates within the same functional parameters. The primary distinction between these parts is product status—205211-1 is obsolete while 1658640-2 is active—and compliance certifications, where 1658640-2 achieves ROHS3 compliance and REACH unaffected status compared to the non-compliant status of the original part.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658640-2 serves as the direct functional equivalent to the obsolete 205211-1. Selection of 1658640-2 is supported by three primary factors: identical electrical and mechanical specifications across all connector parameters, active product status ensuring ongoing availability and manufacturer support, and superior compliance certifications including ROHS3 compliance and REACH unaffected designation. The substitute part is packaged in bulk format and maintains the same shell material, finish, and dielectric specifications. For applications requiring the 50-position D-Sub receptacle housing within the AMPLIMITE HDP-20 series, 1658640-2 provides direct compatibility with the original design while offering improved regulatory compliance and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the 205211-1 and 1658640-2 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including shell size 5 (DD, D), 50-position configuration, 3-row layout, free hanging in-line mounting, unthreaded housing/shell flange, and black polyamide nylon glass-filled dielectric material.

Q: What is the primary reason to substitute 205211-1 with 1658640-2?

A: The 205211-1 is classified as obsolete, while 1658640-2 is active. This substitution ensures continued component availability and manufacturer support. Additionally, 1658640-2 achieves ROHS3 compliance and REACH unaffected status, compared to the non-compliant status of 205211-1.

Q: Do both parts use the same shell material and finish?

A: Yes. Both the 205211-1 and 1658640-2 feature steel shells with yellow chromate plated zinc finish, ensuring equivalent corrosion resistance and electrical properties.

Q: What is the difference in packaging between these parts?

A: The 205211-1 packaging specification is not defined in available documentation. The 1658640-2 is supplied in bulk packaging format.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are classified as signal contact type D-Sub receptacles with identical electrical specifications. The moisture sensitivity level is 1 (Unlimited) for both parts, indicating equivalent environmental performance.

Q: Can 205211-1 be used in new designs?

A: The 205211-1 is obsolete and not recommended for new designs. The 1658640-2 should be specified for all new applications requiring a 50-position D-Sub receptacle housing in the AMPLIMITE HDP-20 series.

Q: Are both parts compliant with current regulatory standards?

A: The 1658640-2 is ROHS3 compliant and REACH unaffected. The 205211-1 is RoHS non-compliant with vendor-undefined REACH status, making it unsuitable for applications with regulatory compliance requirements.
