Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCE17C37SC690 is determined by strict alignment of 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
• Contact Type: Signal
• Shell Material, Finish: Steel, Tin Plated
• Contact Finish: Gold
• Backset Spacing: 0.590" (14.99mm)

Allowable Parameter Variations: Substitute parts may differ in contact finish thickness, current rating, operating temperature range, flange feature design, and additional features, provided the mandatory parameters remain identical and the substitute maintains active product status with RoHS compliance.

The part 5745996-4 from TE Connectivity AMP Connectors qualifies as a substitute based on full alignment of all mandatory parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the FCE17C37SC690 and 5745996-4 maintain active product status and full RoHS compliance, qualifying them for direct substitution in applications requiring 37-position D-Sub receptacle connectors with solder termination.

The 5745996-4 substitute provides enhanced specifications in three areas: increased contact finish thickness (30.0µin versus 15.0µin), higher current rating (6A versus 5A), and extended operating temperature range (-55°C to 105°C versus -40°C to 85°C). These enhancements do not create incompatibility; they represent performance improvements suitable for demanding environmental conditions.

Selection between these parts should be based on application-specific requirements for current capacity and temperature extremes. Both parts satisfy standard industrial D-Sub connector applications with identical mechanical fit and electrical interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for FCE17C37SC690?

A: Yes. Both connectors share identical mechanical and electrical interface specifications: 37-position D-Sub receptacle configuration, right-angle through-hole solder termination, shell size 4 (DC, C), and 0.590" backset spacing. The substitute maintains full compatibility with existing PCB layouts and mating plugs.

Q: What are the differences between these two connectors?

A: The primary differences are contact finish thickness (30.0µin for 5745996-4 versus 15.0µin for FCE17C37SC690), current rating (6A versus 5A), and operating temperature range (-55°C to 105°C versus -40°C to 85°C). The 5745996-4 offers enhanced durability and wider environmental tolerance.

Q: Are both connectors RoHS compliant?

A: Yes. Both FCE17C37SC690 and 5745996-4 are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for unrestricted storage and handling.

Q: What is the significance of shell size 4 (DC, C)?

A: Shell size 4 (DC, C) defines the physical dimensions and contact arrangement of the D-Sub connector housing. This standardized specification ensures mechanical compatibility with all 37-position D-Sub plugs and receptacles conforming to the same shell size classification.

Q: Can these connectors be used in high-temperature applications?

A: The FCE17C37SC690 operates within -40°C to 85°C. The 5745996-4 substitute extends this range to -55°C to 105°C, making it suitable for applications requiring broader temperature tolerance. Application requirements should determine which part is appropriate.

Q: What is the difference between contact finish thickness specifications?

A: Contact finish thickness affects durability and wear resistance. The 5745996-4 provides double the gold plating thickness (30.0µin versus 15.0µin), enhancing contact longevity in high-cycle mating applications.
