Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17C37SC640 are identified based on strict alignment of the following critical parameters:

Mandatory Matching 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
• Shell Material, Finish: Steel, Tin Plated
• Contact Finish: Gold
• Backset Spacing: 0.590" (14.99mm)

Allowable Parameter Variations: Substitute parts may differ in current rating (5A to 6A), operating temperature range (-40°C ~ 85°C to -55°C ~ 105°C), contact finish thickness (15.0µin to 30.0µin), voltage rating presence, and flange feature design (M3 to 4-40), provided these variations do not reduce performance below the original specification requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: FCE17C37SC640

The FCE17C37SC640 maintains Active product status with established supply availability. This connector is RoHS Compliant and carries UL94 V-0 material flammability certification, meeting regulatory requirements for industrial applications. The part is classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Substitute Part: 5745996-4

The TE Connectivity 5745996-4 is functionally equivalent for applications where the following conditions are met:

• Current requirements do not exceed 6A (substitute provides 6A rating versus 5A original specification)
• Operating temperature range of -55°C ~ 105°C is acceptable (substitute provides extended range versus -40°C ~ 85°C original specification)
• Contact finish thickness of 30.0µin (0.76µm) is compatible with application requirements (substitute provides increased thickness versus 15.0µin original specification)
• Voltage rating of 125V is acceptable (substitute specifies voltage rating; original does not)

Both parts are Active products with RoHS Compliance and UL94 V-0 certification. The substitute part offers enhanced electrical performance characteristics and extended environmental operating range, making it suitable for applications with more demanding specifications than the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for FCE17C37SC640?

A: Yes, the 5745996-4 is electrically and mechanically compatible as a substitute. Both connectors share identical connector style, type, position count, row configuration, shell size, mounting type, termination method, shell material finish, contact finish, and backset spacing. The substitute part meets or exceeds the original specification in current rating, operating temperature range, and contact finish thickness.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Current Rating: 5745996-4 provides 6A versus FCE17C37SC640 at 5A; (2) Operating Temperature: 5745996-4 operates from -55°C ~ 105°C versus FCE17C37SC640 at -40°C ~ 85°C; (3) Contact Finish Thickness: 5745996-4 provides 30.0µin (0.76µm) versus FCE17C37SC640 at 15.0µin (0.38µm); (4) Voltage Rating: 5745996-4 specifies 125V while FCE17C37SC640 does not specify voltage rating; (5) Flange Feature: 5745996-4 uses 4-40 mounting holes versus FCE17C37SC640 with M3 mounting holes.

Q: Are both connectors RoHS Compliant?

A: Yes, both FCE17C37SC640 and 5745996-4 are RoHS Compliant and carry UL94 V-0 material flammability certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or use.

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

A: Yes. The 5745996-4 with 6A current rating is suitable for applications requiring 5A or less. Higher current rating capability does not restrict use in lower current applications.

Q: What is the difference in contact finish thickness between these parts?

A: The FCE17C37SC640 has 15.0µin (0.38µm) gold contact finish thickness, while the 5745996-4 has 30.0µin (0.76µm). The thicker finish on the substitute part provides enhanced contact durability and wear resistance.

Q: Are the flange mounting features compatible?

A: The flange features differ: FCE17C37SC640 uses M3 mounting holes, while 5745996-4 uses 4-40 mounting holes. PCB or mounting surface design must accommodate the specific flange feature of the selected connector.

Q: Which connector should I select for extended temperature applications?

A: The 5745996-4 is suitable for applications requiring operation beyond -40°C ~ 85°C range, as it operates from -55°C ~ 105°C. The FCE17C37SC640 is limited to -40°C ~ 85°C operating range.
