FCE17C37SC6DB D-Sub Receptacle 37-Position Connector

Part Overview

The FCE17C37SC6DB is a 37-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets in a right-angle, through-hole configuration with solder termination. The part is currently active in production with 924 units in stock.

D-Sub connectors are essential interface components in industrial, telecommunications, and legacy computing applications where standardized multi-pin connections are required. Equivalent and substitute parts become necessary when original inventory is unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits the use of functionally compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SC6DB is permissible with parts that maintain identical or superior electrical and mechanical characteristics 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)

Acceptable Variation Parameters:

• Current Rating: Substitute must equal or exceed 5A
• Operating Temperature Range: Substitute must encompass or exceed -40°C ~ 85°C
• Contact Finish Thickness: Substitute may exceed 15.0µin (0.38µm)
• Voltage Rating: Substitute may provide additional voltage specification
• Flange Feature: Substitute may differ (Board Side vs. Housing/Shell) provided mechanical fit is maintained

The substitute part TE Connectivity AMP Connectors 5745996-4 meets all mandatory matching parameters and exceeds performance specifications in current rating (6A vs. 5A) and operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C).

Engineering Selection Recommendations

Primary Part: FCE17C37SC6DB

The FCE17C37SC6DB remains the specified component when original design validation, existing inventory, or established supply agreements require the Amphenol ICC product. This part is active in production with adequate stock availability (924 units). It carries full RoHS compliance and UL94 V-0 flammability certification suitable for industrial applications.

Substitute Part: 5745996-4

The TE Connectivity AMP Connectors 5745996-4 (AMPLIMITE HD-20 series) is a direct functional equivalent that meets all mandatory electrical and mechanical specifications. This substitute provides enhanced performance characteristics:

• Higher current rating (6A vs. 5A) accommodates higher-load applications
• Extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C) supports broader environmental conditions
• Thicker gold contact finish (30.0µin vs. 15.0µin) provides enhanced contact durability
• Specified voltage rating (125V) offers additional design documentation

Both parts maintain identical connector geometry, pin configuration, mounting methodology, and termination approach. Both are RoHS compliant with MSL 1 rating and UL94 V-0 flammability certification. The substitute part is currently in stock with 1030 units available.

Selection between these parts depends on application requirements and supply chain considerations. The substitute part is suitable for direct replacement in existing designs without PCB modification or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5745996-4 be used as a direct replacement for the Amphenol FCE17C37SC6DB?

A: Yes. Both connectors share identical shell size (4/DC/C), pin count (37), row configuration (2), mounting type (through-hole right angle), and backset spacing (0.590"). The TE Connectivity part meets or exceeds all electrical specifications of the Amphenol part.

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

A: The primary differences are: (1) Current rating: TE Connectivity provides 6A versus Amphenol's 5A; (2) Operating temperature range: TE Connectivity operates from -55°C to 105°C versus Amphenol's -40°C to 85°C; (3) Contact finish thickness: TE Connectivity provides 30.0µin versus Amphenol's 15.0µin; (4) Voltage rating: TE Connectivity specifies 125V while Amphenol does not specify voltage; (5) Flange feature: Amphenol uses board-side M3 mounting while TE Connectivity uses housing/shell 4-40 mounting.

Q: Are there any mechanical compatibility issues when substituting the TE Connectivity part?

A: The flange feature differs between the two parts. The Amphenol FCE17C37SC6DB uses a board-side M3 flange, while the TE Connectivity 5745996-4 uses a housing/shell 4-40 flange. PCB mounting hole patterns must be verified to ensure compatibility with the substitute part's flange configuration.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability certification, and have MSL 1 (unlimited) moisture sensitivity rating. Both use phosphor bronze contacts with gold finish and steel tin-plated shells.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable. The TE Connectivity 5745996-4 offers performance advantages (higher current rating, extended temperature range, thicker contact finish) that may provide additional design margin. The Amphenol FCE17C37SC6DB is appropriate when existing supply agreements or design validation history favors this manufacturer.

Q: What is the difference in packaging between these parts?

A: The Amphenol FCE17C37SC6DB is supplied in standard packaging (not specified in detail). The TE Connectivity 5745996-4 is supplied in bulk packaging. Packaging differences do not affect connector functionality or electrical performance.

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

A: Electrical and functional interchangeability is confirmed. Mechanical interchangeability depends on the specific PCB mounting hole pattern. If the original design uses the Amphenol board-side M3 flange, the PCB mounting holes must be verified or modified to accommodate the TE Connectivity housing/shell 4-40 flange before substitution.
