Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SC61B is determined by strict equivalence across 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

Allowable Variation Parameters:

• Current Rating: Substitute must equal or exceed 5A
• Operating Temperature: Substitute must encompass or exceed -40°C ~ 85°C range
• Contact Finish Thickness: Substitute may differ while maintaining gold plating
• Flange Feature: Board-side or housing/shell mounting configurations are both acceptable for D-Sub receptacles
• Voltage Rating: Substitute may include voltage specification where original does not

The substitute part 5745996-4 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) meets all mandatory matching parameters and exceeds allowable variation thresholds with a 6A current rating and -55°C ~ 105°C operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

FCE17C37SC61B (Amphenol ICC):

• Active product status with established supply (742 pieces in stock)
• RoHS Compliant certification
• UL94 V-0 flammability rating
• Board-side M3 flange mounting configuration
• Suitable for applications within -40°C ~ 85°C operating range at 5A maximum current

5745996-4 (TE Connectivity):

• Active product status with higher inventory availability (1030 pieces in stock)
• RoHS Compliant certification
• UL94 V-0 flammability rating
• Housing/shell 4-40 flange mounting configuration
• Extended operating temperature range (-55°C ~ 105°C) and higher current rating (6A) provide additional performance margin
• Thicker gold contact plating (30.0µin vs. 15.0µin) offers enhanced durability in high-cycle mating applications

Both parts satisfy identical D-Sub 37 position receptacle specifications and comply with equivalent regulatory standards. Selection between these parts depends on specific application requirements regarding operating temperature extremes, current demands, and flange mounting geometry compatibility with the target PCB design.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 directly replace the FCE17C37SC61B in existing designs?

A: The 5745996-4 is electrically and mechanically equivalent for D-Sub 37 position receptacle applications. However, the flange mounting configuration differs: FCE17C37SC61B uses board-side M3 mounting, while 5745996-4 uses housing/shell 4-40 mounting. PCB hole patterns and mounting hardware must be verified for compatibility before substitution.

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

A: The primary differences are: (1) flange mounting style (board-side M3 vs. housing/shell 4-40), (2) current rating (5A vs. 6A), (3) operating temperature range (-40°C ~ 85°C vs. -55°C ~ 105°C), and (4) contact finish thickness (15.0µin vs. 30.0µin). All other electrical and mechanical parameters are identical.

Q: Are both connectors RoHS compliant?

A: Yes, both FCE17C37SC61B and 5745996-4 are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited) and UL94 V-0 flammability ratings.

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

A: The 5745996-4 supports operating temperatures up to 105°C, compared to 85°C for the FCE17C37SC61B. For applications requiring extended high-temperature operation, the 5745996-4 is the appropriate selection.

Q: Does the thicker gold plating on the 5745996-4 provide any advantage?

A: The 5745996-4 features 30.0µin (0.76µm) gold contact plating compared to 15.0µin (0.38µm) on the FCE17C37SC61B. Thicker plating provides enhanced resistance to wear and corrosion in applications involving frequent mating cycles or harsh environmental exposure.

Q: Are the backset spacing measurements identical?

A: Yes, both connectors maintain identical backset spacing of 0.590" (14.99mm), ensuring compatible pin-to-pin alignment within the 37 position, 2-row D-Sub configuration.
