FCE17C37PB44B D-Sub 37-Position Right Angle Solder Plug Connector

Part Overview

The FCE17C37PB44B is a 37-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This connector features male pins, right-angle through-hole mounting, and solder termination. The part is classified as Active product status with 1123 units in current inventory. D-Sub connectors of this configuration are essential for applications requiring multi-pin signal distribution with standardized mechanical and electrical interfaces. Substitute parts may be required due to inventory availability, specific flange feature requirements, or extended operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17C37PB44B are qualified based on the following critical parameters that must remain constant:

• Connector Type: Plug with male pins
• Number of Positions: 37 positions
• Number of Rows: 2 rows
• Shell Size, Connector Layout: 4 (DC, C)
• Mounting Type: Through hole, right angle
• Termination Method: Solder
• Current Rating: 5A per contact
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: RoHS Compliant

The three substitute parts (D37P13A4GL00LF, D37P13A4GV00LF, D37P13A4GX00LF) are all from the Amphenol ICC (FCI) Delta D series and maintain these core parameters. Variations exist in flange feature design, shell material finish, contact material composition, and operating temperature range, which are secondary parameters that do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain Active product status and are RoHS compliant, meeting current regulatory requirements. Selection between the main part and substitutes is determined by specific application requirements:

FCE17C37PB44B is suitable for applications operating within -40°C to 85°C temperature range with board-side flange mounting requirements.

D37P13A4GL00LF provides extended operating temperature range (-55°C to 125°C) with housing/shell M3 flange mounting, appropriate for industrial environments requiring wider thermal tolerance.

D37P13A4GV00LF offers extended operating temperature range (-55°C to 125°C) with mating-side female screwlock (4-40) flange feature, suitable for applications requiring secure mating-side locking mechanisms.

D37P13A4GX00LF provides extended operating temperature range (-55°C to 125°C) with housing/shell 4-40 flange mounting and ROHS3 compliance status, appropriate for applications with enhanced regulatory requirements.

All substitute parts feature tin-nickel plated steel shells compared to the tin-plated shell of the main part, and utilize brass contacts instead of phosphor bronze. These material differences do not affect electrical performance within the specified current and voltage parameters.

Frequently Asked Questions (FAQ)

Q: Can D37P13A4GL00LF, D37P13A4GV00LF, and D37P13A4GX00LF be used interchangeably with FCE17C37PB44B?

A: These parts are functionally interchangeable for applications within the overlapping operating temperature range (-40°C to 85°C) and standard signal applications. However, flange feature differences require verification of mounting compatibility with the specific PCB or housing design. Backset spacing variation (0.405" versus 0.409") must be evaluated for tight mechanical tolerances.

Q: What is the difference between the three substitute parts?

A: The primary differences are flange feature design and REACH compliance status. D37P13A4GL00LF features housing/shell M3 mounting. D37P13A4GV00LF includes mating-side female screwlock (4-40) for enhanced connection security. D37P13A4GX00LF features housing/shell 4-40 mounting with REACH Affected status. All three maintain identical electrical specifications and operating temperature range.

Q: Why does the backset spacing differ between the main part and substitutes?

A: Backset spacing (0.405" for FCE17C37PB44B versus 0.409" for Delta D series) reflects design differences between the FCE17 and Delta D series. This 0.004" (0.11mm) variation must be considered in applications with precise mechanical tolerances or existing connector cavity designs.

Q: Are the contact material differences significant?

A: The main part uses phosphor bronze contacts while substitutes use brass contacts. Both materials are standard for D-Sub connectors and maintain equivalent electrical performance at the specified 5A current rating and signal contact classification. Material selection does not affect functional interchangeability.

Q: Which part should be selected for extended temperature applications?

A: All three substitute parts (D37P13A4GL00LF, D37P13A4GV00LF, D37P13A4GX00LF) support -55°C to 125°C operating range, compared to -40°C to 85°C for the main part. Selection among the three substitutes depends on flange feature requirements specific to the application.

Q: What is the significance of ROHS3 compliance for D37P13A4GX00LF?

A: ROHS3 compliance indicates adherence to the most current RoHS directive requirements. D37P13A4GX00LF is suitable for applications with enhanced regulatory compliance requirements. The main part and other substitutes maintain standard RoHS compliance.
