Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SC250 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
• Backset spacing: 0.590" (14.99mm)

Compliance Parameters:

• Material flammability rating: UL94 V-0
• RoHS compliance status: RoHS Compliant
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 5745996-4 from TE Connectivity AMP Connectors meets all mandatory equivalence parameters and compliance requirements, establishing it as a direct functional substitute for the FCE17C37SC250.

Parameter Comparison

Engineering Selection Recommendations

The FCE17C37SC250 and 5745996-4 are functionally equivalent D-Sub receptacle connectors meeting identical mechanical and electrical interface requirements. Both parts are active products with RoHS compliance and UL94 V-0 flammability certification, confirming suitability for regulated applications.

The 5745996-4 substitute demonstrates enhanced performance specifications in current rating (6A versus 5A) and operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C), along with increased contact finish thickness (30.0µin versus 15.0µin). These enhancements provide additional margin in demanding thermal or high-current environments without compromising interface compatibility.

Selection between these parts should be based on application requirements, inventory availability, and supplier lead times. Both parts satisfy identical form, fit, and function criteria for D-Sub 37-position receptacle applications with right-angle solder termination.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC250?

A: Yes. Both connectors share identical mechanical interfaces (37 positions, 2 rows, shell size 4, right-angle through-hole mounting) and electrical termination (solder). Pin-to-pin compatibility is established through matching backset spacing (0.590") and contact configuration.

Q: What are the differences between these two parts?

A: The primary differences are current rating (5745996-4 rated at 6A versus FCE17C37SC250 at 5A), operating temperature range (5745996-4 extends to -55°C ~ 105°C versus -40°C ~ 85°C), and contact finish thickness (5745996-4 provides 30.0µin versus 15.0µin). These represent performance enhancements rather than functional incompatibilities.

Q: Are both parts RoHS compliant?

A: Yes. Both the FCE17C37SC250 and 5745996-4 are RoHS compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for commercial and industrial applications.

Q: What is the significance of backset spacing in D-Sub connector selection?

A: Backset spacing (0.590" for both parts) defines the distance from the connector mounting face to the contact insertion point. Identical backset spacing ensures mechanical compatibility with mating connectors and printed circuit board layouts.

Q: Does contact finish thickness affect connector performance?

A: Contact finish thickness influences durability and wear resistance during mating cycles. The 5745996-4 provides thicker gold plating (30.0µin), which may extend service life in high-cycle applications, though both finishes meet standard performance requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the application does not specifically require the FCE17C37SC250 part number for traceability or qualification purposes. Mechanical and electrical interfaces are identical, supporting direct substitution in new assemblies and field replacements.
