Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 205211-2 is based on electrical and mechanical parameter equivalence within the D-Sub connector category. The substitute part 1658640-1 maintains identical specifications across all critical parameters: connector style, type, position count, row configuration, shell size layout, contact type, mounting method, flange design, shell material and finish, dielectric composition, and color. Both parts belong to the AMPLIMITE HDP-20 series and are classified as receptacles for female contacts with 50-position, 3-row configurations in shell size 5 (DD, D).

The substitution is valid based on the following key parameters:

• Connector Style: D-Sub (identical)
• Connector Type: Receptacle for Female Contacts (identical)
• Number of Positions: 50 (identical)
• Number of Rows: 3 (identical)
• Shell Size, Connector Layout: 5 (DD, D) (identical)
• Contact Type: Signal (identical)
• Mounting Type: Free Hanging (In-Line) (identical)
• Flange Feature: Housing/Shell (Unthreaded) (identical)
• Shell Material, Finish: Steel, Tin Plated (identical)
• Dielectric Material: Polyamide (PA), Nylon, Glass Filled (identical)
• Color: Black (identical)

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658640-1 is the direct substitute for the obsolete 205211-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 205211-2 is classified as obsolete, while the 1658640-1 is active. Active product status ensures continued availability, technical support, and manufacturing consistency.

Compliance and Certifications: The 1658640-1 is ROHS3 compliant, whereas the 205211-2 is RoHS non-compliant. For applications subject to RoHS regulations, the 1658640-1 satisfies compliance requirements. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Electrical and Mechanical Equivalence: All critical parameters are identical between the two parts, including connector style, type, position count, row configuration, shell size layout, contact type, mounting method, shell material and finish, and dielectric material. This equivalence ensures direct functional substitution without design modification.

Moisture Sensitivity: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Inventory Availability: The 1658640-1 is available in bulk packaging with 1355 pieces in stock, providing supply chain reliability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1658640-1 directly replace the 205211-2 in existing designs?

A: Yes. The 1658640-1 is electrically and mechanically equivalent to the 205211-2 across all specified parameters. Both are 50-position, 3-row D-Sub receptacles with identical shell size, material composition, and mounting configuration. Direct substitution is supported without design modification.

Q: What is the primary reason for substituting the 205211-2?

A: The 205211-2 is classified as obsolete. The 1658640-1 is an active product from the same manufacturer and series, ensuring continued supply chain access and manufacturing consistency.

Q: Are there compliance differences between these parts?

A: Yes. The 1658640-1 is ROHS3 compliant, while the 205211-2 is RoHS non-compliant. For applications subject to RoHS directives, the 1658640-1 is the appropriate selection. Both parts share identical ECCN and HTSUS classifications.

Q: What is the shell finish thickness specification for the 1658640-1?

A: The 1658640-1 has a specified shell finish thickness of 200µin (5.08µm). The 205211-2 does not include a documented finish thickness specification.

Q: Are contacts included with these housings?

A: No. Both the 205211-2 and 1658640-1 are housings only. Contacts are not included and must be sourced separately.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints. These connectors do not require special moisture control during storage or handling.

Q: What packaging options are available for the substitute part?

A: The 1658640-1 is available in bulk packaging. The 205211-2 packaging specification is not documented.

Q: Are these parts suitable for free-hanging or in-line mounting applications?

A: Yes. Both parts are specified for free-hanging (in-line) mounting type, supporting applications requiring this mounting configuration.
