Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub 37-position receptacle connectors is determined by strict alignment of the following parameters:

Critical Parameters (Must Match):

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 37
• Number of rows: 2
• Shell size and connector layout: 4 (DC, C)
• Termination method: Solder
• Mounting type: Through Hole, Right Angle

Compatible Variation Parameters:

• Shell material finish (tin-plated, nickel-plated)
• Contact material (phosphor bronze, brass, copper alloy)
• Contact finish thickness (30.0µin, flash)
• Current rating (6A, 5A, 3A per contact)
• Voltage rating (125V, unspecified)
• Flange feature configuration (housing/shell, mating side screwlock)
• Packaging format (bulk, tray)
• Dielectric material composition

The three substitute parts listed below meet all critical parameters and are therefore electrically and mechanically compatible with the main part number 5745996-4.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity AMP Connectors 5745996-4 (Primary Part)

The primary part is an active product with RoHS compliance and UL94 V-0 flammability rating. It provides the highest current rating (6A) and specified voltage rating (125V) among all listed options. The tin-plated steel shell and phosphor bronze contacts with 30.0µin gold plating offer enhanced corrosion resistance. Operating temperature range extends to 105°C. This part is suitable for applications requiring maximum current capacity and extended high-temperature operation.

NorComp Inc. 183-037-213R171 (Substitute)

This part is an active product with ROHS3 compliance and UL94 V-0 flammability rating. It provides panel mount capability in addition to through-hole mounting. Current rating is 5A, which is lower than the primary part. Operating temperature range matches the primary part at -55°C to 105°C. Nickel-plated steel shell and brass contacts with flash gold plating are suitable for general-purpose applications. Tray packaging is available. This part is suitable when panel mount flexibility is required and 5A current capacity is acceptable.

NorComp Inc. 183-037-213R541 (Substitute)

This part is an active product with ROHS3 compliance and UL94 V-0 flammability rating. It features a mating side female screwlock flange for board lock capability, providing enhanced mechanical retention. Current rating is 5A. Operating temperature range matches the primary part at -55°C to 105°C. Nickel-plated steel shell and brass contacts with flash gold plating are suitable for applications requiring positive mechanical locking. Tray packaging is available. This part is suitable when board lock retention is required and 5A current capacity is acceptable.

Mercury United Electronics, Inc. 626-037-262-012 (Substitute)

This part is an active product with ROHS3 compliance and UL94 V-0 flammability rating. It features board edge mounting capability and includes mounting brackets and shielding. Current rating is 3A per contact, which is lower than other options. Operating temperature range is limited to -55°C to 85°C, which is 20°C lower than the primary part. Nickel-plated steel shell and copper alloy contacts with flash gold plating are suitable for shielded applications. Bulk packaging is available. This part is suitable for shielded board edge applications where 3A current capacity and 85°C maximum temperature are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-037-213R171 be used as a direct replacement for the TE Connectivity 5745996-4?

A: The NorComp 183-037-213R171 meets all critical electrical and mechanical parameters for D-Sub 37-position receptacle connectors. However, the current rating is 5A compared to 6A for the primary part. If the application requires 6A current capacity, this substitute is not suitable. If the application operates at 5A or below, this part is compatible. The nickel-plated finish and brass contacts provide equivalent performance to the primary part in most applications.

Q: What is the difference between the two NorComp substitute parts?

A: Both NorComp parts (183-037-213R171 and 183-037-213R541) share identical electrical specifications and operating temperature ranges. The primary difference is the flange feature: the 183-037-213R171 has a housing/shell flange (4-40), while the 183-037-213R541 has a mating side female screwlock flange with board lock capability. Select the 183-037-213R541 when positive mechanical locking to the mating connector is required.

Q: Why does the Mercury 626-037-262-012 have a lower current rating?

A: The Mercury part specifies 3A per contact, which is lower than the 6A rating of the primary part and the 5A rating of the NorComp substitutes. This lower rating reflects the design specifications of the Mercury connector. Applications requiring current capacity above 3A per contact should not use this part. The Mercury part is optimized for shielded applications with board edge mounting.

Q: What is the impact of the operating temperature difference in the Mercury part?

A: The Mercury 626-037-262-012 has a maximum operating temperature of 85°C, compared to 105°C for the primary part and NorComp substitutes. Applications operating above 85°C require the primary part or NorComp substitutes. The 20°C difference may be significant in high-temperature environments such as industrial equipment or automotive under-hood applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part is RoHS Compliant. All three substitute parts are ROHS3 Compliant. All parts meet RoHS requirements and are suitable for applications with RoHS compliance mandates.

Q: What packaging options are available?

A: The primary TE Connectivity part is supplied in bulk packaging. The two NorComp substitutes are supplied in tray packaging. The Mercury substitute is supplied in bulk packaging. Packaging selection depends on inventory management and handling requirements for the application.

Q: Can the shell material finish (tin-plated vs. nickel-plated) affect connector performance?

A: Both tin-plated and nickel-plated finishes provide corrosion protection and are suitable for general-purpose applications. Tin plating offers slightly better solderability, while nickel plating provides enhanced corrosion resistance in harsh environments. The choice between these finishes depends on specific environmental conditions and soldering process requirements.

Q: What is the significance of contact finish thickness?

A: The primary part specifies 30.0µin (0.76µm) gold plating thickness, while all substitute parts specify flash gold plating. Flash plating is a thin, minimal-thickness coating that meets electrical contact requirements while reducing material cost. Both thicknesses provide adequate electrical conductivity and corrosion protection for D-Sub connectors in standard applications.
