Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17C37SC69B are identified based on strict equivalence of core electrical and mechanical parameters. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• 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
• Shell Material, Finish: Steel, Tin Plated
• Contact Finish: Gold
• Contact Material: Phosphor Bronze

Allowable Variation Parameters:

• Current Rating (Amps): Substitute must equal or exceed 5A
• Operating Temperature: Substitute must encompass or exceed -40°C ~ 85°C range
• Contact Finish Thickness: Variation permitted (15.0µin minimum acceptable)
• Flange Feature: Variation permitted (Board Side M3 or Housing/Shell 4-40)
• Voltage Rating: Variation permitted when specified
• Features: Variation permitted (Filter, Mounting Brackets, Ground Strap)

The substitute part 5745996-4 meets all critical matching parameters and exceeds allowable variation thresholds, qualifying it as a direct substitute.

Engineering Selection Recommendations

Primary Part: FCE17C37SC69B

The FCE17C37SC69B remains the primary specification for new designs and procurement when available. This connector is actively produced by Amphenol ICC (Commercial Products), carries RoHS compliance certification, and meets all specified electrical and mechanical requirements for standard applications.

Substitute Part: 5745996-4

The TE Connectivity AMP Connectors part number 5745996-4 (AMPLIMITE HD-20 series) is a qualified substitute for the FCE17C37SC69B. This substitute part demonstrates full compatibility across all critical parameters:

• Identical connector configuration: 37 position D-Sub receptacle, female sockets, right-angle through-hole solder termination
• Identical shell size and layout: Size 4 (DC, C) with matching backset spacing
• Identical contact materials and finishes: Phosphor bronze with gold plating
• Identical flammability and compliance ratings: UL94 V-0, RoHS compliant, EAR99 classification
• Enhanced electrical performance: 6A current rating (exceeds 5A requirement) and extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C)
• Enhanced contact durability: 30.0µin gold plating thickness (exceeds 15.0µin specification)

The substitute part is actively produced and available in higher inventory quantities (1030 pcs versus 666 pcs). Selection of the substitute part is appropriate for applications requiring extended temperature performance, higher current capacity, or improved contact longevity.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC69B?

A: Yes. The 5745996-4 is a direct substitute. Both connectors share identical connector type, position count, shell size, mounting configuration, and termination method. The substitute part meets or exceeds all electrical and mechanical specifications of the primary part.

Q: What are the differences between these two connectors?

A: The primary differences are: (1) Manufacturer: Amphenol ICC versus TE Connectivity; (2) Series designation: FCE17 versus AMPLIMITE HD-20; (3) Flange feature: Board side M3 versus Housing/Shell 4-40; (4) Current rating: 5A versus 6A; (5) Operating temperature range: -40°C ~ 85°C versus -55°C ~ 105°C; (6) Contact finish thickness: 15.0µin versus 30.0µin; (7) Features: Filter and Mounting Brackets versus Ground Strap. All other parameters are identical.

Q: Are there any compatibility concerns when substituting the 5745996-4 for the FCE17C37SC69B?

A: No compatibility concerns exist for standard applications. Both connectors use identical contact materials, shell materials, and electrical specifications. The substitute part's enhanced current rating and extended temperature range present no compatibility issues. The different flange feature (Housing/Shell 4-40 versus Board side M3) requires verification of mounting hole compatibility on the target PCB.

Q: Which connector should be selected for new designs?

A: For new designs, either connector is acceptable. The FCE17C37SC69B is appropriate for standard applications within the specified temperature and current ranges. The 5745996-4 is preferred for applications requiring extended temperature performance (-55°C to 105°C), higher current capacity (6A), or enhanced contact durability. Flange mounting requirements should determine final selection.

Q: What is the significance of the different flange features?

A: The FCE17C37SC69B uses a board-side M3 flange, while the 5745996-4 uses a housing/shell 4-40 flange. Both are through-hole right-angle configurations. The flange feature determines the mounting hole pattern and fastening method on the PCB. Verification of target PCB hole compatibility is required before substitution.

Q: Are both connectors RoHS compliant?

A: Yes. Both the FCE17C37SC69B and 5745996-4 are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or use.
