TE Connectivity 206973-1 D-Sub 50-Position Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 206973-1 is a 50-position D-Sub receptacle connector with female sockets, right-angle through-hole mounting, and solder termination. This connector is part of the AMPLIMITE HDP-20 series and is classified as obsolete. The part features gold-plated contacts, UL94 V-0 flammability rating, and operates across a temperature range of -55°C to 105°C with a 125V voltage rating and 6A current capacity.

Due to its obsolete product status, locating equivalent or substitute components is necessary for ongoing system maintenance, repair, and new design implementations where this connector specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 206973-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 50
• Number of rows: 3
• Shell size and layout: 5 (DD, D)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Voltage rating: 125V
• Current rating: 6A
• Operating temperature range: -55°C to 105°C
• Material flammability rating: UL94 V-0
• Contact finish: Gold
• RoHS compliance: ROHS3 Compliant

The substitute part TE Connectivity 5745116-2 meets all mandatory matching parameters and is therefore classified as a direct equivalent for the obsolete 206973-1.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5745116-2 is a direct equivalent substitute for the obsolete TE Connectivity 206973-1. Both connectors are manufactured by TE Connectivity within the AMPLIMITE HDP-20 series and share identical electrical and mechanical specifications across all critical parameters.

Compliance and Certification Alignment:

• Both parts maintain ROHS3 compliance, satisfying regulatory requirements for hazardous substance restrictions
• Both parts carry UL94 V-0 flammability certification, meeting fire safety standards
• Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling
• Both parts are classified under the same ECCN (EAR99) and HTSUS codes

Product Status Consideration: The 206973-1 is classified as obsolete, while the 5745116-2 is classified as active. Selection of the active substitute part ensures continued availability, manufacturer support, and supply chain reliability for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can the 5745116-2 be used as a direct replacement for the 206973-1 in existing designs?

A: Yes. The 5745116-2 meets all mandatory electrical and mechanical parameters of the 206973-1, including connector type, position count, shell size, mounting configuration, termination method, voltage and current ratings, temperature range, and flammability certification. Both parts are from the same manufacturer and series.

Q: What is the primary difference between these two parts?

A: The 206973-1 is obsolete, while the 5745116-2 is active. The 5745116-2 also includes mounting brackets as a feature and specifies a backset spacing of 0.545" (13.84mm). The dielectric material differs slightly: the 206973-1 uses thermoplastic, while the 5745116-2 uses polyamide (PA) nylon with glass filling. The 5745116-2 specifies phosphor bronze contact material and steel tin-plated shell material.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level. Both are classified under the same export control and tariff codes.

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

A: The 5745116-2 is supplied in bulk packaging, whereas the 206973-1 packaging specification was not provided in the available data.

Q: Are both parts suitable for the same operating temperature and voltage conditions?

A: Yes. Both parts operate across the identical temperature range of -55°C to 105°C and share the same 125V voltage rating and 6A current capacity.
