Frequently Asked Questions (FAQ)

Q: Can D37P13A4GL00LF, D37P13A4GV00LF, or D37P13A4GX00LF be used as direct replacements for FCE17C37PB49B?

A: These parts are electrically and mechanically compatible substitutes for the FCE17C37PB49B within the constraints of their flange feature configurations. The primary differences are flange type, shell material finish, contact material composition, and operating temperature range. Selection depends on specific application requirements for mounting configuration and environmental operating conditions.

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

A: The three substitute parts differ in flange feature configuration: D37P13A4GL00LF features Housing/Shell (M3) flange, D37P13A4GV00LF features Mating Side Female Screwlock (4-40) flange, and D37P13A4GX00LF features Housing/Shell (4-40) flange. All three share identical electrical specifications, current rating, voltage rating, and operating temperature range. D37P13A4GX00LF carries ROHS3 Compliant status and REACH Affected designation, while the other two are RoHS Compliant.

Q: Are there temperature rating differences between the main part and substitutes?

A: Yes. The FCE17C37PB49B operates from -40°C to 85°C, while all three substitute parts (D37P13A4GL00LF, D37P13A4GV00LF, D37P13A4GX00LF) operate from -55°C to 125°C. The substitute parts provide extended temperature capability for applications requiring operation in extreme thermal environments.

Q: What is the difference between Phosphor Bronze and Brass contact materials?

A: The FCE17C37PB49B uses Phosphor Bronze contacts, while the substitute parts use Brass contacts. Both materials are suitable for signal-level D-Sub connectors with 5A current rating. Material selection affects contact spring characteristics and corrosion resistance properties. Application-specific requirements determine which material is appropriate.

Q: How do the shell finishes differ between these parts?

A: The FCE17C37PB49B features Tin-plated steel shell, while all substitute parts feature Tin-Nickel plated steel shell. Tin-Nickel plating provides enhanced corrosion resistance compared to Tin plating, particularly in humid or corrosive environments.

Q: What does "Flash" gold contact finish thickness mean compared to 15.0µin?

A: Flash gold finish is a minimal thickness gold plating applied to contact surfaces, typically less than 5µin. The FCE17C37PB49B specifies 15.0µin (0.38µm) gold finish thickness, which provides thicker gold plating for enhanced wear resistance and contact reliability. Flash finish is suitable for applications with lower contact cycling requirements.

Q: Are all these parts RoHS compliant?

A: The FCE17C37PB49B, D37P13A4GL00LF, and D37P13A4GV00LF are RoHS Compliant. The D37P13A4GX00LF is ROHS3 Compliant, which represents an updated compliance designation. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the significance of REACH Affected status on D37P13A4GX00LF?

A: REACH Affected designation indicates that the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This requires additional documentation and compliance tracking for applications in European Union markets. The other substitute parts show REACH Unaffected status.

Q: What is the difference between Board Side, Housing/Shell, and Mating Side flange configurations?

A: Board Side flange (FCE17C37PB49B) mounts on the PCB surface with fasteners on the connector body facing the board. Housing/Shell flange (D37P13A4GL00LF, D37P13A4GX00LF) mounts with fasteners on the shell exterior. Mating Side flange (D37P13A4GV00LF) mounts with fasteners on the mating connector interface. Flange selection depends on mechanical mounting requirements and available space in the application.

Q: Can I use D37P13A4GL00LF with M3 mounting if my application requires 4-40 fasteners?

A: No. The D37P13A4GL00LF features M3 flange mounting, which is not compatible with 4-40 fastener specifications. For 4-40 mounting requirements, use D37P13A4GX00LF (Housing/Shell 4-40) or D37P13A4GV00LF (Mating Side Female Screwlock 4-40).

Q: What is the backset spacing difference, and does it affect compatibility?

A: The FCE17C37PB49B has 0.405" (10.29mm) backset spacing, while substitute parts have 0.409" (10.40mm) backset spacing. This 0.004" difference is within standard connector tolerance ranges and does not affect electrical or mechanical compatibility for standard PCB applications.

Q: Which substitute part should I select for maximum environmental durability?

A: D37P13A4GX00LF provides maximum environmental durability through Tin-Nickel plated shell finish, extended operating temperature range (-55°C to 125°C), and ROHS3 Compliant status. This part is suitable for harsh environmental conditions, wide temperature fluctuations, and applications requiring enhanced regulatory compliance.
