Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SC240 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 and layout: 4 (DC, C)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold
• Backset spacing: 0.590" (14.99mm)
• Contact material: Phosphor Bronze
• Material flammability rating: UL94 V-0
• RoHS compliance: Required

The substitute part 5745996-4 from TE Connectivity AMP Connectors meets all mandatory equivalence parameters and is therefore qualified as a direct substitute. Both parts share identical mechanical interfaces, electrical contact configurations, and regulatory compliance status, enabling interchangeability in applications where the FCE17C37SC240 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the FCE17C37SC240 and 5745996-4 are active products with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts is based on application-specific requirements:

FCE17C37SC240 (Amphenol ICC):

• Suitable for applications with operating temperature range of -40°C to 85°C
• Current rating of 5A per contact
• Contact finish thickness of 15.0µin

5745996-4 (TE Connectivity):

• Suitable for applications with extended operating temperature range of -55°C to 105°C
• Current rating of 6A per contact
• Contact finish thickness of 30.0µin, providing enhanced durability in high-cycle mating environments
• Includes ground strap feature
• Rated for 125V operation

Both parts maintain identical mechanical interfaces and electrical contact configurations, ensuring direct substitution capability. The choice between them depends on whether the application requires the extended temperature range, higher current capacity, or enhanced contact durability provided by the TE Connectivity alternative.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC240?

A: Yes. Both connectors share identical mechanical mounting interfaces, shell size and layout (4 DC, C), backset spacing (0.590"), and electrical contact configuration (37 positions, 2 rows, female sockets). Both are RoHS compliant and rated UL94 V-0. The connectors are mechanically and electrically interchangeable in applications where the FCE17C37SC240 is specified.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Current rating: FCE17C37SC240 is rated 5A versus 5745996-4 at 6A; (2) Operating temperature: FCE17C37SC240 operates -40°C to 85°C versus 5745996-4 at -55°C to 105°C; (3) Contact finish thickness: FCE17C37SC240 has 15.0µin versus 5745996-4 at 30.0µin; (4) 5745996-4 includes a ground strap feature and 125V voltage rating.

Q: Which part should be selected for high-temperature applications?

A: The 5745996-4 is suitable for applications requiring operation up to 105°C, whereas the FCE17C37SC240 is limited to 85°C maximum. Application requirements determine the appropriate selection.

Q: Are both parts available in the same packaging?

A: The FCE17C37SC240 packaging information is not specified in the provided data. The 5745996-4 is supplied in bulk packaging. Packaging availability should be confirmed with the respective manufacturers or authorized distributors.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

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

A: The 5745996-4 features 30.0µin (0.76µm) gold plating compared to 15.0µin (0.38µm) on the FCE17C37SC240. Thicker plating provides extended durability in high-cycle mating applications and enhanced corrosion resistance.
