Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCE17C37SC2EB is determined by 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
• Contact Material: Phosphor Bronze
• Backset Spacing: 0.590" (14.99mm)

Allowable Variation Parameters:

• Current Rating (Amps): May exceed primary specification
• Contact Finish Thickness: May exceed primary specification
• Operating Temperature Range: May exceed primary specification
• Voltage Rating: May be specified on substitute when not specified on primary
• Flange Feature: May differ (Unthreaded vs. 4-40 threaded)
• Dielectric Material composition: May vary within thermoplastic category
• Features: May include additional features (Ground Strap, Mounting Brackets)

The substitute part 5745996-4 from TE Connectivity AMP Connectors meets all mandatory matching parameters and qualifies as a direct substitute with enhanced electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (FCE17C37SC2EB): The FCE17C37SC2EB remains the specified component for applications requiring exact compliance with the original design parameters. This part is actively manufactured, RoHS compliant, and carries UL94 V-0 flammability certification. The connector is suitable for signal applications within the -40°C to 85°C operating temperature range and 5A current capacity.

Substitute Part Selection (5745996-4): The TE Connectivity 5745996-4 qualifies as a direct substitute when the primary part is unavailable or when enhanced electrical and thermal performance is beneficial. This substitute provides:

• Higher current rating (6A vs. 5A)
• Extended operating temperature range (-55°C to 105°C vs. -40°C to 85°C)
• Thicker gold contact finish (30.0µin vs. 15.0µin)
• Specified voltage rating (125V)
• Threaded flange feature (4-40) for enhanced mechanical retention

Both parts maintain identical mechanical compatibility, connector geometry, and core electrical characteristics. Selection between these parts depends on application-specific requirements for current capacity, temperature extremes, and mechanical mounting preferences.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC2EB in existing designs?

A: Yes. Both connectors share identical connector style, type, position count, row configuration, shell size, mounting type, termination method, shell material finish, contact finish material, and backset spacing. The 5745996-4 provides equal or superior performance across all electrical and thermal parameters.

Q: What is the difference in flange design between these two connectors?

A: The FCE17C37SC2EB features an unthreaded housing/shell flange, while the 5745996-4 includes a 4-40 threaded flange. The threaded design on the substitute part provides additional mechanical retention options through screw fastening. Both designs accommodate through-hole right-angle mounting.

Q: Are there any compliance or certification differences between these parts?

A: Both connectors are RoHS compliant, carry UL94 V-0 flammability ratings, and maintain MSL 1 (Unlimited) moisture sensitivity levels. Both are actively manufactured and available in new original inventory. The 5745996-4 includes a specified 125V voltage rating, while the primary part does not specify voltage rating.

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

A: The 5745996-4 provides double the gold contact finish thickness (30.0µin vs. 15.0µin). This enhanced plating thickness increases contact durability and corrosion resistance, particularly beneficial in applications requiring extended service life or exposure to corrosive environments.

Q: Can the 5745996-4 be used in applications requiring the -40°C to 85°C temperature range?

A: Yes. The 5745996-4 operating temperature range of -55°C to 105°C fully encompasses the -40°C to 85°C specification of the primary part. The substitute is suitable for all temperature conditions specified for the FCE17C37SC2EB.

Q: What inventory considerations should guide part selection?

A: The FCE17C37SC2EB has 875 pieces in stock, while the 5745996-4 has 1030 pieces available. For immediate procurement, either part supports adequate inventory levels. For long-term supply chain planning, the substitute part offers slightly higher availability.

Q: Are there any mechanical mounting differences that affect PCB layout or enclosure design?

A: Both connectors use identical through-hole right-angle mounting with 0.590" (14.99mm) backset spacing. The threaded flange on the 5745996-4 provides optional screw-mount capability, but does not require design changes. Existing PCB layouts and enclosure designs accommodate both parts without modification.
