FCE17C37PB640 Equivalent & Substitute Parts

Part Overview

The FCE17C37PB640 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 actively produced and maintained in inventory. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design requirements permit functional equivalents within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17C37PB640 are qualified based on the following critical parameters that must remain constant:

• Connector Style & Type: D-Sub plug with male pins
• Position Count & Row Configuration: 37 positions in 2-row layout
• Shell Size: Size 4 (DC, C)
• Mounting Configuration: Through-hole, right-angle orientation
• Termination Method: Solder
• Current Rating: 5A per contact
• Flammability Compliance: UL94 V-0
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity: MSL 1

All three substitute parts (D37P13A4GL00LF, D37P13A4GV00LF, D37P13A4GX00LF) meet these core requirements. Variations exist in shell material finish, contact material, flange feature design, and operating temperature range, which are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with RoHS requirements. Selection among the substitute options depends on specific application requirements:

D37P13A4GL00LF features housing/shell M3 mounting, matching the flange configuration of the primary part FCE17C37PB640. This part provides the closest mechanical alignment for applications requiring M3 threaded fastening.

D37P13A4GV00LF incorporates mating-side female screwlock (4-40) fastening, suitable for applications requiring connector-integrated locking mechanisms on the mating interface.

D37P13A4GX00LF provides housing/shell 4-40 mounting with ROHS3 compliance designation, appropriate for applications with enhanced regulatory requirements beyond standard RoHS compliance.

All substitute parts operate across an extended temperature range (-55°C to 125°C) compared to the primary part (-40°C to 85°C), providing thermal margin for demanding environments. The Delta D series substitutes specify 300V voltage rating, whereas the primary part does not specify this parameter.

Minor variations in backset spacing (0.409" versus 0.405") and contact material (brass versus phosphor bronze) exist between the primary and substitute parts. These differences fall within standard D-Sub connector design tolerances for the 37-position size 4 configuration.

Frequently Asked Questions (FAQ)

Q: Can D37P13A4GL00LF, D37P13A4GV00LF, or D37P13A4GX00LF be used as direct replacements for FCE17C37PB640?

A: Yes, all three parts are functionally equivalent substitutes. They share identical connector style, position count, row configuration, shell size, mounting type, and termination method. Differences in shell finish, contact material, flange feature, and operating temperature range do not prevent substitution in applications where the primary part is unavailable.

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

A: The primary differences are flange feature design and RoHS designation. D37P13A4GL00LF and D37P13A4GX00LF both use housing/shell mounting but differ in fastener size (M3 versus 4-40). D37P13A4GV00LF incorporates mating-side female screwlock fastening. D37P13A4GX00LF carries ROHS3 compliance, while the other two are standard RoHS Compliant.

Q: Are there compatibility concerns with backset spacing differences?

A: The backset spacing difference (0.405" for FCE17C37PB640 versus 0.409" for Delta D substitutes) represents a 0.004" variation. This falls within standard manufacturing tolerances for D-Sub connectors and does not create compatibility issues with standard PCB layouts designed for 37-position size 4 D-Sub connectors.

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

A: All three substitute parts operate from -55°C to 125°C, compared to the primary part's -40°C to 85°C range. Any of the three substitutes provides extended thermal capability. Selection among them should be based on flange feature requirements and regulatory compliance needs.

Q: Do the substitute parts have different contact material specifications?

A: Yes. The primary part FCE17C37PB640 uses phosphor bronze contacts, while all three substitute parts use brass contacts. Both materials are standard for D-Sub signal connectors and maintain equivalent electrical performance at the 5A current rating specified for this connector category.

Q: What packaging format is supplied for the substitute parts?

A: All three substitute parts are supplied in tray packaging, whereas the primary part packaging is not specified in the provided data.

Q: Are all parts RoHS compliant?

A: Yes. FCE17C37PB640 and D37P13A4GL00LF and D37P13A4GV00LF are RoHS Compliant. D37P13A4GX00LF carries ROHS3 Compliant designation, which represents an enhanced compliance level.
