TE Connectivity 5206973-1 D-Sub 50 Position Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5206973-1 is a 50 position D-Sub receptacle connector with female sockets, configured for right-angle through-hole solder termination. This connector is part of the AMPLIMITE HD-20 series and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure ongoing component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5206973-1 with the active TE Connectivity 5745116-2 is based on strict equivalence of the following critical parameters:

Electrical Compatibility:

• Identical connector style (D-Sub)
• Identical connector type (Receptacle, Female Sockets)
• Identical number of positions (50)
• Identical number of rows (3)
• Identical shell size and layout (5, DD, D)
• Identical current rating (6A)
• Identical voltage rating (125V)
• Identical operating temperature range (-55°C to 105°C)

Mechanical Compatibility:

• Identical mounting type (Through Hole, Right Angle)
• Identical termination method (Solder)
• Identical contact type (Signal)
• Identical contact finish (Gold)

Regulatory Compliance:

• Both parts are ROHS3 Compliant
• Both parts have MSL rating of 1 (Unlimited)
• Both parts carry ECCN EAR99 classification

The 5745116-2 is an active product from the AMPLIMITE HDP-20 series, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5745116-2 is the direct substitute for the obsolete 5206973-1 based on electrical and mechanical parameter equivalence. Both connectors maintain identical performance specifications across all critical functional parameters: 50 position configuration, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range.

The 5745116-2 offers the advantage of active product status, ensuring availability and supply chain continuity. Both parts are ROHS3 compliant and carry identical regulatory classifications (ECCN EAR99, HTSUS 8536.69.4040).

Physical differences exist in backset spacing (0.590" versus 0.545"), flange feature design (unthreaded housing versus mating side with 4-40 screws), and dielectric material composition (thermoplastic versus glass-filled polyamide). These differences do not affect electrical compatibility but require mechanical design verification for PCB layout and mounting bracket compatibility in specific applications.

Frequently Asked Questions (FAQ)

Q: Can the 5745116-2 be used as a direct replacement for the 5206973-1 in all applications?

A: The 5745116-2 is electrically and functionally equivalent to the 5206973-1 across all signal, power, and environmental specifications. However, the backset spacing difference of 0.045" (1.15mm) and the different flange feature design require verification of PCB layout and mechanical mounting compatibility in the specific application.

Q: What is the difference in backset spacing between these two connectors?

A: The 5206973-1 has a backset spacing of 0.590" (14.99mm), while the 5745116-2 has a backset spacing of 0.545" (13.84mm). This 0.045" (1.15mm) difference may affect PCB footprint design and should be evaluated during component substitution.

Q: Are both connectors RoHS compliant?

A: Yes, both the 5206973-1 and 5745116-2 are ROHS3 compliant and carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the primary reason to substitute the 5206973-1?

A: The 5206973-1 is classified as obsolete. The 5745116-2 is an active product from TE Connectivity's current AMPLIMITE HDP-20 series, providing assured long-term availability and supply chain support.

Q: Do both connectors support the same current and voltage ratings?

A: Yes, both connectors are rated for 6A current and 125V voltage, with identical operating temperature ranges of -55°C to 105°C.

Q: What is the difference in flange features between these connectors?

A: The 5206973-1 features an unthreaded housing/shell flange, while the 5745116-2 features a mating side design with standard 4-40 screws. This difference affects mounting bracket compatibility and should be evaluated for the specific application.

Q: Are the dielectric materials different between these two connectors?

A: Yes, the 5206973-1 uses thermoplastic dielectric material, while the 5745116-2 uses polyamide (PA) nylon with glass filling. Both materials support the identical operating temperature range and electrical specifications.
