FCE17C37SC650 Equivalent & Substitute Parts

Part Overview

The FCE17C37SC650 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 classified as an active product with full RoHS compliance and unlimited moisture sensitivity rating. D-Sub connectors of this configuration are essential in applications requiring standardized, high-density signal interconnection with proven mechanical durability and electrical performance across industrial and commercial environments. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when application requirements necessitate alternative specifications within compatible parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SC650 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)
• Material flammability rating: UL94 V-0
• Contact material: Phosphor Bronze
• RoHS compliance: Required

The substitute part 5745996-4 from TE Connectivity AMP Connectors meets all mandatory equivalence parameters. Variations in non-critical parameters such as current rating, contact finish thickness, operating temperature range, and flange feature design do not preclude substitution when the above critical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: FCE17C37SC650

The FCE17C37SC650 maintains active product status with confirmed inventory of 933 units. This connector carries full RoHS compliance certification and UL94 V-0 flammability rating, meeting regulatory requirements for commercial and industrial applications. The part is suitable for deployment in environments operating within the -40°C to 85°C temperature range with current requirements up to 5A per contact.

Substitute Part: 5745996-4

The TE Connectivity 5745996-4 is an active product with 1030 units in inventory. This substitute maintains identical compliance certifications (RoHS compliant, UL94 V-0, EAR99 export classification) and shares all critical mechanical and electrical parameters with the primary part. The substitute offers an extended operating temperature range (-55°C to 105°C) and higher current rating (6A), providing enhanced performance margins in demanding thermal environments. Contact finish thickness is doubled (30.0µin versus 15.0µin), which may provide extended contact life in high-cycle mating applications.

Both parts are suitable for direct substitution in applications where the specified parameters are required. Selection between the two should be based on inventory availability, delivery lead time, and application-specific thermal or current requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC650?

A: Yes. Both connectors share identical specifications for connector style, type, position count, shell size, mounting configuration, termination method, shell material, contact finish type, backset spacing, flammability rating, and contact material. Both are RoHS compliant with unlimited moisture sensitivity rating and EAR99 export classification.

Q: What are the differences between these two connectors?

A: The primary differences are: (1) Contact finish thickness—5745996-4 has 30.0µin versus 15.0µin for FCE17C37SC650; (2) Current rating—5745996-4 is rated for 6A versus 5A for FCE17C37SC650; (3) Operating temperature range—5745996-4 operates from -55°C to 105°C versus -40°C to 85°C for FCE17C37SC650; (4) Flange feature—5745996-4 uses 4-40 mounting holes versus M3 for FCE17C37SC650; (5) Voltage rating—5745996-4 is rated for 125V while FCE17C37SC650 has no specified voltage rating; (6) Features—5745996-4 includes a ground strap while FCE17C37SC650 includes board lock and filter features.

Q: Are there any compatibility concerns with the different flange features?

A: The flange features differ (M3 versus 4-40 mounting holes). PCB mounting hole patterns must be verified to ensure compatibility with the selected connector's flange configuration. The backset spacing is identical at 0.590" (14.99mm), ensuring consistent board-to-connector positioning.

Q: Does the higher contact finish thickness on the 5745996-4 affect electrical performance?

A: Contact finish thickness does not alter electrical performance characteristics. The thicker gold plating on the 5745996-4 may extend contact life in high-cycle mating applications by providing additional wear resistance.

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

A: Interchangeability requires verification of PCB mounting hole patterns to accommodate the different flange designs. If the existing design uses M3 mounting holes, the FCE17C37SC650 is the appropriate selection. If the design uses 4-40 mounting holes, the 5745996-4 is appropriate. Electrical and mechanical performance are equivalent when mounting compatibility is confirmed.

Q: What is the significance of the ground strap feature on the 5745996-4?

A: The ground strap on the 5745996-4 provides an additional grounding path independent of the signal contacts. This feature is present on the substitute but not on the primary part. Applications requiring this grounding capability should specify the 5745996-4.

Q: Are both parts suitable for high-temperature applications?

A: The FCE17C37SC650 operates to 85°C maximum. The 5745996-4 operates to 105°C maximum. For applications exceeding 85°C, the 5745996-4 is the appropriate selection.
