FCE17C37SC200 D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The FCE17C37SC200 is a 37-position D-Sub receptacle connector manufactured by Amphenol ICC, featuring female sockets with right-angle through-hole solder termination. This connector is designed for applications requiring reliable signal transmission in industrial and commercial environments. The part maintains Active product status with 888 units in current inventory stock.

D-Sub connectors of this configuration are essential in legacy and modern systems requiring standardized parallel data transmission, control signaling, and serial communication interfaces. Equivalent substitute parts are identified when manufacturers discontinue production lines, inventory becomes constrained, or system design requirements necessitate alternative sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCE17C37SC200 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• 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 Method: Solder
• Shell Material, Finish: Steel, Tin Plated
• Contact Finish: Gold
• Contact Material: Phosphor Bronze
• Dielectric Material: Thermoplastic
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Parameter Variations: Substitute parts may exceed the main part specifications in the following parameters without compromising compatibility:

• Current Rating: Substitute may be rated higher than 5A
• Contact Finish Thickness: Substitute may exceed 15.0µin (0.38µm)
• Operating Temperature Range: Substitute may provide extended range beyond -40°C ~ 85°C
• Voltage Rating: Substitute may include voltage specification where main part does not

The substitute part 5745996-4 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) meets all mandatory matching parameters and provides enhanced specifications in current rating (6A), contact finish thickness (30.0µin), operating temperature range (-55°C ~ 105°C), and voltage rating (125V).

Parameter Comparison

Engineering Selection Recommendations

Primary Part: FCE17C37SC200

The FCE17C37SC200 maintains Active product status with established inventory availability (888 units in stock). This part is suitable for applications operating within the specified temperature range (-40°C ~ 85°C) and current requirements up to 5A. The connector carries full RoHS compliance certification and Moisture Sensitivity Level 1 rating, indicating no special handling requirements during storage or assembly.

Substitute Part: 5745996-4

The TE Connectivity 5745996-4 connector is qualified as a direct substitute based on identical mechanical and electrical core specifications. This part is also Active with higher inventory availability (1030 units in stock). The substitute provides enhanced performance margins through higher current rating (6A versus 5A), extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C), and increased contact finish thickness (30.0µin versus 15.0µin).

Both parts maintain RoHS compliance and Moisture Sensitivity Level 1 classification. Selection between these parts should be based on application-specific requirements for current capacity, temperature extremes, and inventory availability. The substitute part's enhanced specifications do not introduce incompatibility with systems designed for the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for FCE17C37SC200 in existing designs?

A: Yes. Both connectors share identical mechanical mounting (through-hole, right-angle), electrical pin configuration (37 positions, 2 rows, shell size 4), and termination method (solder). The substitute part's enhanced current rating and operating temperature range do not create incompatibility with existing PCB layouts or mating connectors.

Q: What is the significance of the different contact finish thicknesses (15.0µin versus 30.0µin)?

A: Contact finish thickness affects durability and wear resistance during mating cycles. The 5745996-4 provides thicker gold plating (30.0µin), which extends contact life in high-cycle applications. Both thicknesses meet industry standards for signal integrity and corrosion resistance in the specified operating environments.

Q: Are there differences in the dielectric materials between these connectors?

A: The FCE17C37SC200 specifies Thermoplastic, Glass Filled dielectric material, while the 5745996-4 specifies Thermoplastic dielectric material. Both materials provide adequate electrical insulation and mechanical support. The glass-filled variant in the primary part offers enhanced rigidity; the standard thermoplastic in the substitute provides equivalent electrical performance.

Q: What does the flange feature difference (Unthreaded versus 4-40) mean for installation?

A: The FCE17C37SC200 features an unthreaded housing/shell, while the 5745996-4 includes 4-40 threaded mounting holes. Both configurations support through-hole PCB mounting. The threaded variant allows optional mechanical fastening for additional strain relief, but this does not affect basic connector compatibility or electrical function.

Q: Are both parts suitable for RoHS-compliant applications?

A: Yes. Both the FCE17C37SC200 and 5745996-4 carry RoHS Compliant certification, meeting EU Directive 2011/65/EU requirements for restricted substance elimination. Both parts are suitable for applications requiring RoHS compliance documentation.

Q: What is the inventory status for each part?

A: FCE17C37SC200 has 888 units in stock (Amphenol ICC). The substitute 5745996-4 has 1030 units in stock (TE Connectivity). Both parts are classified as New Original In Stock with Active product status.
