TE Connectivity 205212-2 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 205212-2 is a D-Sub connector housing plug designed for 50-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 industrial and commercial applications.

The 205212-2 carries an obsolete product status, indicating that TE Connectivity has discontinued active manufacturing and support for this part number. Identifying equivalent and substitute parts is necessary to maintain system compatibility, ensure continued supply chain availability, and support legacy equipment maintenance and repair operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 205212-2 is determined by strict equivalence across all mechanical and electrical parameters that define connector interchangeability. The following parameters establish the substitution criteria:

Critical Matching Parameters:

• Connector style (D-Sub)
• Connector type (Plug for Male Contacts)
• Position count (50 positions)
• Row configuration (3 rows)
• Shell size and layout (Size 5, DD/D configuration)
• Contact type (Signal)
• Mounting method (Free Hanging, In-Line)
• Flange design (Unthreaded housing/shell)
• Shell material and finish (Steel, Tin Plated)
• Dielectric material (Polyamide, Nylon, Glass Filled)
• Color (Black)
• Series compatibility (AMPLIMITE HDP-20)

The substitute part 1658641-1 maintains complete alignment with all these parameters, ensuring mechanical and electrical compatibility with systems originally designed for the 205212-2.

Parameter Comparison

Engineering Selection Recommendations

The 1658641-1 serves as the direct substitute for the obsolete 205212-2 based on complete parameter equivalence across all mechanical and electrical specifications. Both parts are manufactured by TE Connectivity within the AMPLIMITE HDP-20 series and maintain identical connector geometry, contact configuration, and material composition.

Product Status Consideration: The 205212-2 is obsolete, while 1658641-1 maintains active product status with TE Connectivity. This distinction ensures ongoing availability, manufacturing consistency, and vendor support for the substitute part.

Compliance Advantage: The 1658641-1 achieves ROHS3 compliance, whereas the 205212-2 is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the 1658641-1 provides regulatory alignment while maintaining full functional compatibility.

Additional Feature: The 1658641-1 incorporates grounding indents, an enhancement not specified in the 205212-2 documentation. This feature provides improved grounding performance without affecting mechanical or electrical interchangeability.

Packaging: The 1658641-1 is supplied in bulk packaging, whereas the 205212-2 packaging specification is not provided. Bulk packaging supports high-volume assembly operations and reduces per-unit material handling costs.

Frequently Asked Questions (FAQ)

Q: Can the 1658641-1 directly replace the 205212-2 in existing assemblies?

A: Yes. The 1658641-1 maintains complete mechanical and electrical equivalence with the 205212-2 across all specified parameters, including connector style, position count, row configuration, shell size, mounting type, material composition, and dielectric properties. Direct substitution is supported without design modification.

Q: What is the significance of the grounding indents feature on the 1658641-1?

A: Grounding indents are a structural feature that enhances grounding performance by providing improved contact surface area and electrical path definition. This feature does not affect mechanical compatibility or interchangeability with the 205212-2.

Q: Does the RoHS3 compliance of the 1658641-1 affect compatibility with the 205212-2?

A: No. RoHS compliance status reflects manufacturing and material sourcing practices rather than functional performance. The 1658641-1 maintains identical electrical and mechanical characteristics to the 205212-2 while meeting modern environmental regulations.

Q: Are there differences in shell finish thickness between the two parts?

A: The 1658641-1 specifies a shell finish thickness of 200µin (5.08µm), while the 205212-2 does not provide this specification. Both parts use steel with tin plating as the shell material and finish. The specified thickness on the 1658641-1 represents standard tin plating for this connector series.

Q: What packaging considerations apply when transitioning from 205212-2 to 1658641-1?

A: The 1658641-1 is supplied in bulk packaging, which differs from the unspecified packaging of the 205212-2. Bulk packaging is standard for high-volume production environments and may require adjustment to receiving, storage, and inventory management procedures.

Q: Are both parts suitable for the same operating environments?

A: Both parts share identical material composition, dielectric properties, and moisture sensitivity ratings (MSL 1, Unlimited). They are suitable for equivalent operating environments within the specifications of the AMPLIMITE HDP-20 series.

Q: Does the 1658641-1 require different contact specifications than the 205212-2?

A: No. Both parts are designed for use with identical male contact sets within the AMPLIMITE HDP-20 series. Contact specifications remain unchanged during substitution.
