TE Connectivity 747193-2 D-Sub 50 Position Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 747193-2 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 an active product. The 747193-2 features a steel tin-plated shell with gold-plated phosphor bronze contacts, rated for 6A at 125V, and operates across a temperature range of -55°C to 105°C.

Equivalent and substitute parts are identified to address inventory availability, compliance requirements, or specific application needs while maintaining electrical and mechanical compatibility within the D-Sub connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 747193-2 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Connector style (D-Sub), type (Receptacle, Female Sockets), and position count (50)
• Shell size and layout (5 DD, D), mounting configuration (Through Hole, Right Angle)
• Electrical ratings (6A current, 125V voltage)
• Operating temperature range (-55°C to 105°C)
• Contact material (Phosphor Bronze) and finish (Gold)
• Termination method (Solder)
• Shell material and finish (Steel, Tin Plated)
• Flange feature (Mating Side, Female Screwlock 4-40)
• Material flammability rating (UL94 V-0)
• Backset spacing (0.545" / 13.84mm)

Parts 5747193-2 and 5747193-1 meet all these criteria and are therefore direct substitutes. Variations in dielectric material specification and RoHS compliance status do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—747193-2, 5747193-2, and 5747193-1—are active products from TE Connectivity AMP Connectors and are electrically and mechanically equivalent for D-Sub 50 position receptacle applications.

Compliance Considerations:

The 747193-2 is RoHS non-compliant, while both 5747193-2 and 5747193-1 are ROHS3 compliant. Applications subject to RoHS regulations should specify either 5747193-2 or 5747193-1.

All three parts are REACH affected and carry EAR99 export classification.

Inventory and Availability:

• 747193-2: 831 pieces in stock
• 5747193-2: 2160 pieces in stock
• 5747193-1: 1555 pieces in stock

Selection between substitute parts should be based on compliance requirements and inventory availability, as all three maintain identical electrical and mechanical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are 5747193-2 and 5747193-1 direct substitutes for 747193-2?

A: Yes. Both parts are direct substitutes. All critical electrical and mechanical parameters are identical, including connector type, position count, shell size, mounting configuration, current and voltage ratings, operating temperature range, and contact materials. The parts are interchangeable in applications where the connector specifications match.

Q: What is the difference between 747193-2 and the substitute parts?

A: The primary differences are RoHS compliance status and dielectric material specification. The 747193-2 is RoHS non-compliant, while 5747193-2 and 5747193-1 are ROHS3 compliant. The 747193-2 does not specify dielectric material, while 5747193-2 and 5747193-1 specify Polyamide (PA), Nylon, Glass Filled. These differences do not affect functional compatibility.

Q: Can I use 5747193-1 or 5747193-2 in place of 747193-2 in my design?

A: Yes, provided your application does not have specific requirements for RoHS non-compliance or unspecified dielectric material. Both substitute parts maintain all electrical and mechanical specifications required for D-Sub 50 position receptacle applications.

Q: What is the significance of the contact finish thickness specification?

A: The 747193-2 and 5747193-1 specify contact finish thickness as "Flash," while 5747193-2 does not specify this parameter. Flash plating indicates a thin gold coating applied to the phosphor bronze contact material. This does not affect electrical performance or mechanical compatibility.

Q: Are there any packaging or inventory considerations when selecting between these parts?

A: All three parts are supplied in bulk packaging. Inventory levels differ: 747193-2 has 831 pieces, 5747193-2 has 2160 pieces, and 5747193-1 has 1555 pieces in stock. Selection should account for project lead times and quantity requirements.

Q: Do all three parts meet the same electrical ratings?

A: Yes. All three parts are rated for 6A current at 125V and operate across the same temperature range of -55°C to 105°C. They are suitable for identical electrical applications.

Q: What mounting configuration do these connectors use?

A: All three parts use through-hole, right-angle mounting with a backset spacing of 0.545 inches (13.84mm). They include mounting brackets and feature a female screwlock (4-40) on the mating side flange.
