Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37PC4D0 is determined by strict equivalence across the following critical parameters:

Core Compatibility Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (37)
• Number of rows (2)
• Shell size and layout (4, DC, C)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Current rating (5A)
• Backset spacing (0.590" / 14.99mm)
• Material flammability rating (UL94 V-0)
• Contact finish (Gold)

Allowable Variations in Substitute Parts:

• Shell material finish (Tin Plated vs. Nickel Plated)
• Contact material (Phosphor Bronze vs. Brass)
• Contact finish thickness (15.0µin vs. Flash)

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183 series parts directly replace the Amphenol FCE17C37PC4D0 in existing designs?

A: Yes, all four NorComp substitute parts maintain electrical and mechanical compatibility across core parameters including connector style, pin count, shell size, mounting type, termination method, and current rating. The 37-position D-Sub plug configuration, 2-row layout, shell size 4 (DC, C), right-angle through-hole mounting, and 5A current rating are identical. Differences in shell finish (nickel vs. tin plating), contact material (brass vs. phosphor bronze), and flange configuration are allowable variations that do not affect functional compatibility in standard D-Sub applications.

Q: What is the difference between the four NorComp substitute parts?

A: The primary differences are in flange feature configuration and specific feature sets. Part 183-037-113R161 has an unthreaded housing/shell flange. Part 183-037-113R171 has a 4-40 threaded housing/shell flange matching the primary part's mechanical interface. Parts 183-037-113R541 and 183-037-113R561 both feature mating side female screwlock (4-40) flanges, which provide enhanced connector retention through screw-locking mechanisms. All four parts include grounding indents; 183-037-113R161 and 183-037-113R171 include ground straps, while 183-037-113R541 and 183-037-113R561 include board lock features.

Q: Are there operating temperature considerations when substituting?

A: The primary part (FCE17C37PC4D0) operates from -40°C to 85°C. All four NorComp substitutes operate from -55°C to 105°C, providing an extended temperature range. This extended range is compatible with the primary part's specification and does not create substitution restrictions. Applications operating within the primary part's temperature range will function identically with substitute parts.

Q: What is the difference between tin plating and nickel plating on the shell?

A: The primary part features a tin-plated steel shell, while all NorComp substitutes feature nickel-plated steel shells. Both finishes provide corrosion protection for the steel shell material. Nickel plating offers enhanced corrosion resistance in harsh environments and provides superior wear characteristics. The choice between these finishes depends on application environment and specific corrosion exposure requirements.

Q: How do contact material differences affect substitution?

A: The primary part uses phosphor bronze contacts, while all NorComp substitutes use brass contacts. Both materials are standard for D-Sub connectors and provide adequate electrical conductivity and contact reliability. Phosphor bronze offers slightly higher strength and spring characteristics, while brass provides good electrical conductivity and corrosion resistance. Both materials are acceptable for standard signal distribution applications at the 5A current rating specified.

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

A: Flash plating refers to a very thin gold coating applied to contacts, typically less than 1µin. The primary part specifies 15.0µin (0.38µm) of gold plating. Flash plating is a cost-effective alternative that provides adequate corrosion protection and electrical conductivity for most applications. The thicker 15.0µin plating on the primary part offers extended contact life in high-cycle mating applications. Both finishes are acceptable for standard D-Sub signal applications.

Q: What is the significance of the flange feature differences?

A: Flange features determine the mechanical mounting interface. The primary part and 183-037-113R171 both use 4-40 threaded housing/shell flanges, providing direct mechanical compatibility. Part 183-037-113R161 uses an unthreaded housing/shell flange, suitable for applications not requiring threaded mounting. Parts 183-037-113R541 and 183-037-113R561 use mating side female screwlock (4-40) flanges, which provide screw-locking retention at the mating interface. Selection depends on the specific mechanical mounting requirements of the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part is RoHS Compliant. All four NorComp substitutes are ROHS3 Compliant, which represents an updated compliance standard. ROHS3 compliance is compatible with RoHS requirements and does not create substitution restrictions for applications requiring RoHS compliance.

Q: What is the difference in moisture sensitivity level (MSL)?

A: The primary part and NorComp parts 183-037-113R541 and 183-037-113R561 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling. NorComp parts 183-037-113R161 and 183-037-113R171 are rated "Not Applicable," indicating these parts do not have moisture sensitivity requirements. Both ratings are compatible for standard applications without moisture-related handling restrictions.

Q: Can I use a substitute part with a different flange feature if my PCB is designed for the primary part's flange?

A: Flange feature compatibility depends on your specific PCB design and mounting requirements. If your PCB is designed for the 4-40 threaded housing/shell flange of the primary part (FCE17C37PC4D0), then 183-037-113R171 provides direct mechanical compatibility. Parts with different flange configurations (183-037-113R161 with unthreaded flange, or 183-037-113R541 and 183-037-113R561 with mating side screwlock flanges) may require PCB design modifications or alternative mounting approaches.

Q: What inventory levels are available for each part?

A: Current inventory levels are: FCE17C37PC4D0 (Amphenol ICC) - 1111 units; 183-037-113R161 (NorComp) - 1259 units; 183-037-113R171 (NorComp) - 1346 units; 183-037-113R541 (NorComp) - 1156 units; 183-037-113R561 (NorComp) - 1422 units. All parts are listed as new original stock.
