FCE17C37SC2DB D-Sub Receptacle 37-Position Connector

Part Overview

The FCE17C37SC2DB is a 37-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets in a right-angle, through-hole solder termination configuration with a 4-position shell size (DC, C layout). The part is actively produced and stocked with 806 units available in inventory.

D-Sub connectors of this specification are essential for applications requiring standardized parallel data transmission, legacy equipment interfaces, and industrial control systems. Equivalent substitute parts may be required due to supply chain constraints, inventory availability, or specific application requirements that demand alternative electrical or mechanical characteristics within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SC2DB is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 37
• Number of Rows: 2
• Shell Size, Connector Layout: 4 (DC, C)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Type: Signal
• Shell Material, Finish: Steel, Tin Plated
• Contact Finish: Gold
• Backset Spacing: 0.590" (14.99mm)

Allowable Variation Parameters:

• Current Rating (Amps): May exceed specified rating
• Contact Finish Thickness: May exceed specified thickness
• Operating Temperature Range: May exceed specified range
• Flange Feature: May differ (Unthreaded vs. 4-40 threaded)
• Voltage Rating: May be specified where original is unspecified
• Features: May include additional features (Ground Strap, Mounting Brackets)

The substitute part TE Connectivity AMP Connectors 5745996-4 meets all mandatory equivalence parameters and is therefore a valid substitute for the FCE17C37SC2DB.

Parameter Comparison

Engineering Selection Recommendations

Both the FCE17C37SC2DB and 5745996-4 are active production parts with full RoHS compliance and MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

The TE Connectivity 5745996-4 substitute provides enhanced electrical performance characteristics:

• Current rating of 6A versus 5A on the original part
• Extended operating temperature range of -55°C to 105°C versus -40°C to 85°C
• Increased contact finish thickness of 30.0µin versus 15.0µin

Both parts maintain identical mechanical compatibility through matching shell size (4, DC, C layout), backset spacing (0.590"), and mounting configuration (through-hole, right-angle solder termination).

The 5745996-4 includes a ground strap feature and threaded flange (4-40) compared to the unthreaded housing/shell flange on the FCE17C37SC2DB. These additions do not compromise mechanical interchangeability in standard applications.

Selection between these parts should be based on application-specific requirements for current capacity, temperature extremes, and mechanical mounting preferences.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5745996-4 be used as a direct replacement for the Amphenol FCE17C37SC2DB?

A: Yes. Both connectors share identical specifications for connector style, type, position count, shell size, mounting configuration, and termination method. The 5745996-4 meets all mandatory equivalence parameters for substitution.

Q: What are the differences between these two 37-position D-Sub receptacles?

A: The primary differences are: (1) Current rating: 5745996-4 is rated for 6A versus 5A for FCE17C37SC2DB; (2) Operating temperature range: 5745996-4 operates from -55°C to 105°C versus -40°C to 85°C; (3) Contact finish thickness: 5745996-4 has 30.0µin versus 15.0µin; (4) Flange type: 5745996-4 features a threaded 4-40 flange with ground strap versus unthreaded housing on the original.

Q: Are both parts RoHS compliant?

A: Yes. Both the FCE17C37SC2DB and 5745996-4 are RoHS compliant with MSL 1 rating.

Q: Does the threaded flange on the 5745996-4 affect mechanical compatibility?

A: No. The threaded 4-40 flange on the 5745996-4 is an additional feature that does not prevent mechanical interchangeability. The connector maintains the same shell size, backset spacing, and through-hole right-angle mounting configuration.

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

A: The 5745996-4 provides thicker gold plating (30.0µin versus 15.0µin), which may offer enhanced durability and contact reliability in applications with frequent mating cycles or harsh environmental conditions.

Q: Can I use the 5745996-4 in applications with higher current requirements?

A: The 5745996-4 is rated for 6A compared to the FCE17C37SC2DB at 5A. Applications requiring currents between 5A and 6A can utilize the 5745996-4 within its specified rating.

Q: Are there packaging differences between these parts?

A: The FCE17C37SC2DB is supplied in standard packaging, while the 5745996-4 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
