TE Connectivity 205733-7 D-Sub Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 205733-7 is a 9-position D-Sub plug connector with male pins, designed for through-hole solder termination applications. This connector belongs to the AMPLIMITE HDP-20 series and is classified as an active product. The connector features a steel shell with yellow chromate plated zinc finish, gold-plated brass contacts, and operates across a temperature range of -55°C to 105°C with a 125V voltage rating and 6A current capacity.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same connector category, allowing for component interchangeability in applications where packaging format or compliance requirements differ from the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub connectors is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution include connector type (plug with male pins), position count (9 positions), shell size and layout (1 DE/E), mounting configuration (through hole), termination method (solder), voltage and current ratings (125V, 6A), operating temperature range (-55°C to 105°C), shell material and finish (steel with yellow chromate plated zinc), contact material and finish (brass with gold plating), and dielectric composition (polyamide nylon glass filled).

The identified substitute part maintains all these core parameters while differing in packaging format (tube versus bulk) and contact finish thickness specification (flash versus 30.0µin). These differences do not affect electrical or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the 205733-7 and 5205733-7 connectors are active products from TE Connectivity and maintain complete electrical and mechanical equivalence for D-Sub plug applications requiring 9-position, through-hole solder termination.

The 205733-7 is supplied in bulk packaging and carries an undefined RoHS status. The 5205733-7 is supplied in tube packaging and is RoHS Compliant with REACH Unaffected status. Selection between these parts depends on packaging requirements and regulatory compliance mandates. Applications requiring RoHS compliance or REACH documentation should specify the 5205733-7. Applications with bulk packaging requirements or where RoHS compliance is not applicable should specify the 205733-7.

Both connectors support identical electrical performance across the 125V, 6A operating envelope and maintain the same mechanical interface for D-Sub shell size 1 (DE/E) configurations.

Frequently Asked Questions (FAQ)

Q: Can the 5205733-7 be used as a direct replacement for the 205733-7 in existing designs?

A: Yes. Both connectors maintain identical electrical and mechanical specifications including connector type, pin count, shell size, mounting configuration, voltage rating, current rating, operating temperature range, and contact materials. The primary differences are packaging format (tube versus bulk) and regulatory compliance documentation.

Q: What is the difference between the contact finish specifications listed for these parts?

A: The 205733-7 specifies a contact finish thickness of 30.0µin (0.76µm), while the 5205733-7 specifies a flash gold finish. Both employ gold plating on brass contacts. Flash plating represents a thinner application of gold coating. Both finishes meet the electrical and mechanical requirements for D-Sub signal contact applications.

Q: Are there packaging considerations when substituting between these parts?

A: Yes. The 205733-7 is supplied in bulk packaging, while the 5205733-7 is supplied in tube packaging. Bulk packaging is suitable for high-volume manufacturing operations, while tube packaging provides individual component protection and is appropriate for lower-volume applications or component kits.

Q: Does the RoHS compliance difference affect component selection?

A: RoHS compliance is a regulatory requirement that depends on the end application and target market. The 5205733-7 is RoHS Compliant, making it suitable for applications subject to RoHS directives. The 205733-7 carries an undefined RoHS status. Applications with explicit RoHS requirements should specify the 5205733-7.

Q: Are both connectors suitable for the same operating temperature range?

A: Yes. Both the 205733-7 and 5205733-7 operate across the identical temperature range of -55°C to 105°C and maintain the same UL94 V-0 flammability rating.

Q: What is the inventory status for these parts?

A: The 205733-7 has 1032 pieces in stock (bulk packaging). The 5205733-7 has 1173 pieces in stock (tube packaging). Both are listed as active products.
