Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SC41B 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
• Backset Spacing: 0.590" (14.99mm)

Allowable Variation Parameters:

• Current Rating: May exceed 5A (higher ratings are compatible)
• Operating Temperature: May exceed -40°C ~ 85°C range (wider ranges are compatible)
• Contact Finish Thickness: May vary (both gold-plated options are compatible)
• Flange Feature: Board Side or Housing/Shell mounting are both compatible
• Voltage Rating: Presence of voltage rating does not disqualify substitution

The substitute part 5745996-4 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) meets all mandatory matching parameters and exceeds performance specifications in current rating and operating temperature range, making it a valid equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the FCE17C37SC41B and 5745996-4 are active production parts with RoHS compliance and UL94 V-0 flammability ratings. The selection between these parts should be based on the following considerations:

FCE17C37SC41B (Amphenol ICC):

• Suitable for applications with current requirements up to 5A
• Operating temperature range of -40°C to 85°C
• Board-side flange mounting configuration
• 1046 units currently in stock

5745996-4 (TE Connectivity):

• Suitable for applications with current requirements up to 6A
• Extended operating temperature range of -55°C to 105°C
• Housing/shell flange mounting configuration
• Thicker gold contact finish (30.0µin vs. 15.0µin)
• 1030 units currently in stock
• Includes ground strap feature
• Voltage rating of 125V specified

Both parts are mechanically and electrically interchangeable within the specified parameters. Selection should be driven by application-specific requirements for current capacity, temperature extremes, and mounting configuration preferences.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC41B?

A: Yes. Both connectors share identical core specifications: 37-position D-Sub receptacle configuration, 2-row layout, shell size 4 (DC, C), through-hole right-angle solder termination, and 0.590" backset spacing. The 5745996-4 exceeds the performance envelope of the FCE17C37SC41B in current rating (6A vs. 5A) and operating temperature range (-55°C to 105°C vs. -40°C to 85°C).

Q: What is the difference in flange mounting between these parts?

A: The FCE17C37SC41B features a board-side flange with 4-40 mounting holes. The 5745996-4 features a housing/shell flange with 4-40 mounting holes. Both configurations are compatible with standard D-Sub mounting practices and do not affect electrical performance.

Q: Does the thicker gold plating on the 5745996-4 affect compatibility?

A: No. The contact finish thickness difference (30.0µin on the 5745996-4 vs. 15.0µin on the FCE17C37SC41B) does not affect mating compatibility or electrical performance. Both exceed standard gold plating requirements for D-Sub connectors.

Q: Are there any packaging differences between these parts?

A: The FCE17C37SC41B is supplied in standard packaging. The 5745996-4 is supplied in bulk packaging. Both are suitable for production assembly and component selection.

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 through the connector shell. This feature does not affect compatibility with the FCE17C37SC41B and may provide enhanced EMI/RFI shielding in applications where such performance is required.

Q: Can I use the FCE17C37SC41B in applications requiring the extended temperature range of the 5745996-4?

A: No. The FCE17C37SC41B is rated for -40°C to 85°C operation. Applications requiring operation below -40°C or above 85°C must use the 5745996-4, which is rated for -55°C to 105°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the FCE17C37SC41B and 5745996-4 are RoHS compliant and carry UL94 V-0 flammability ratings.
