FCE17C37SC25B D-Sub Receptacle 37-Position Connector

Part Overview

The FCE17C37SC25B 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 solder termination configuration with a 4-position shell size (DC, C layout). The connector is actively produced and maintains RoHS compliance with UL94 V-0 flammability rating. Equivalent and substitute parts are identified when mechanical compatibility, electrical performance parameters, and termination methods align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCE17C37SC25B is determined by strict alignment of the following critical parameters:

Mechanical Compatibility Requirements:

• Connector style must be D-Sub
• Connector type must be Receptacle with Female Sockets
• Position count must be 37
• Row configuration must be 2 rows
• Shell size and layout must be 4 (DC, C)
• Mounting type must be Through Hole, Right Angle
• Backset spacing must be 0.590" (14.99mm)

Electrical and Material Requirements:

• Termination method must be Solder
• Shell material and finish must be Steel, Tin Plated
• Contact finish must be Gold
• Contact material must be Phosphor Bronze
• Material flammability rating must be UL94 V-0
• RoHS compliance status must be maintained

Performance Characteristics:

• Current rating must meet or exceed 5A
• Operating temperature range must encompass or exceed -40°C ~ 85°C
• Moisture sensitivity level must be 1 (Unlimited)

The substitute part 5745996-4 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) satisfies all mechanical compatibility requirements and maintains electrical performance specifications that equal or exceed the original part parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: FCE17C37SC25B

The FCE17C37SC25B remains the specified component when original part availability and exact parameter matching are required. This connector is actively produced by Amphenol ICC (Commercial Products), maintains RoHS compliance, and carries UL94 V-0 flammability certification. Current inventory of 736 pieces supports immediate procurement.

Substitute Part: 5745996-4

The 5745996-4 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) is a qualified substitute when the primary part is unavailable. This connector maintains identical mechanical compatibility across all critical parameters including shell size, position count, mounting configuration, and backset spacing. Electrical performance specifications equal or exceed the original part: current rating increases from 5A to 6A, operating temperature range expands from -40°C ~ 85°C to -55°C ~ 105°C, and contact finish thickness increases from 15.0µin to 30.0µin. Both parts maintain RoHS compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. The substitute part carries higher inventory availability (1030 pieces) and includes a ground strap feature. Voltage rating of 125V is specified for the substitute part.

Selection between these parts is determined by availability, delivery timeline, and application-specific requirements for extended temperature operation or enhanced current capacity.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC25B in existing designs?

A: Yes. The 5745996-4 maintains identical mechanical compatibility across all critical parameters: 37-position D-Sub receptacle configuration, 2-row layout, shell size 4 (DC, C), through-hole right-angle mounting, 0.590" backset spacing, and solder termination. Both connectors use steel tin-plated shells, gold-plated phosphor bronze contacts, and maintain UL94 V-0 flammability and RoHS compliance. The substitute part meets or exceeds electrical performance specifications.

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

A: The primary differences are: (1) Contact finish thickness is 15.0µin for the FCE17C37SC25B versus 30.0µin for the 5745996-4; (2) Current rating is 5A versus 6A respectively; (3) Operating temperature range is -40°C ~ 85°C versus -55°C ~ 105°C; (4) The 5745996-4 includes a ground strap feature and specifies 125V voltage rating; (5) Manufacturers differ (Amphenol ICC versus TE Connectivity). All other parameters remain identical.

Q: Are both connectors RoHS compliant?

A: Yes. Both the FCE17C37SC25B and 5745996-4 are RoHS compliant and carry UL94 V-0 material flammability certification.

Q: What is the significance of the contact finish thickness difference?

A: The 5745996-4 provides thicker gold plating (30.0µin versus 15.0µin), which enhances contact durability and corrosion resistance over extended operational life and repeated mating cycles.

Q: Can these connectors be used in applications requiring extended temperature operation?

A: The FCE17C37SC25B operates within -40°C ~ 85°C. The 5745996-4 extends this range to -55°C ~ 105°C, providing capability for applications requiring lower minimum temperatures or higher maximum temperatures. Selection depends on specific application thermal requirements.

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

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

Q: Are there packaging differences between these parts?

A: The FCE17C37SC25B packaging is not specified in the provided data. The 5745996-4 is supplied in Bulk packaging. Specific packaging requirements should be confirmed with the respective manufacturers or distributors.

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

A: The ground strap provides an additional grounding path, which can enhance electromagnetic shielding and signal integrity in applications requiring improved EMI/RFI performance. This feature is present on the 5745996-4 but not specified for the FCE17C37SC25B.
