FCE17C37PC490 Equivalent & Substitute Parts

Part Overview

The FCE17C37PC490 is a 37-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This right-angle, solder-terminated connector features male pins in a 2-row configuration with shell size 4 (DC, C) layout. The connector is designed for through-hole mounting applications and is currently in active product status with 998 pieces in stock.

Substitute parts are necessary when original inventory is unavailable, when alternative manufacturers are preferred for supply chain diversification, or when specific flange and feature configurations better suit application requirements while maintaining electrical and mechanical compatibility.

All substitute parts maintain the core electrical specifications (37-position, 5A current rating, gold contact finish, UL94 V-0 flammability) and mechanical compatibility (shell size 4, right-angle solder termination, 0.590" backset spacing) required for direct substitution in applications originally designed for the FCE17C37PC490.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-037-113R161 directly replace the Amphenol FCE17C37PC490?

A: The 183-037-113R161 is electrically and mechanically compatible with the FCE17C37PC490 across all core parameters (37-position, 5A rating, shell size 4, right-angle solder termination). The primary difference is the unthreaded housing/shell flange versus the 4-40 threaded flange on the original part. Compatibility depends on whether your application requires threaded flange mounting.

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

A: The four NorComp parts differ in flange configuration and features. The 183-037-113R161 has an unthreaded housing/shell flange with ground strap. The 183-037-113R171 has a 4-40 threaded housing/shell flange with ground strap. The 183-037-113R541 and 183-037-113R561 both feature mating side female screwlock (4-40) flanges with board lock. All four maintain identical electrical specifications and operating temperature range.

Q: Are there temperature rating differences between the original and substitute parts?

A: Yes. The FCE17C37PC490 operates from -40°C to 85°C, while all four NorComp substitutes operate from -55°C to 105°C. The NorComp parts provide an extended temperature range suitable for more demanding thermal environments.

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

A: The FCE17C37PC490 specifies 15.0µin (0.38µm) gold contact finish thickness, while all NorComp substitutes specify flash gold finish. Flash finish is a thin, economical plating applied to provide corrosion protection without the thickness of standard plating. Both finishes provide gold contact surfaces for signal integrity.

Q: Do all parts have the same shell material?

A: The FCE17C37PC490 uses steel with tin plating, while all NorComp substitutes use steel with nickel plating. Both materials provide corrosion resistance and structural integrity for D-Sub connectors.

Q: What is the difference between phosphor bronze and brass contact materials?

A: The FCE17C37PC490 uses phosphor bronze contacts, while NorComp substitutes use brass contacts. Both materials provide adequate electrical conductivity and mechanical durability for 5A signal applications. Contact material selection does not affect electrical compatibility.

Q: Are all parts RoHS compliant?

A: The FCE17C37PC490 is RoHS Compliant. All four NorComp substitutes are ROHS3 Compliant, which represents a more recent RoHS compliance standard. Both compliance levels are acceptable for applications requiring RoHS certification.

Q: Which substitute part has the highest inventory availability?

A: The 183-037-113R561 has the highest inventory with 1422 pieces in stock, followed by 183-037-113R171 with 1346 pieces, 183-037-113R161 with 1259 pieces, and 183-037-113R541 with 1156 pieces.

Q: What does "board lock" feature mean?

A: Board lock is a mechanical feature that secures the connector to the printed circuit board during assembly and operation. The FCE17C37PC490, 183-037-113R541, and 183-037-113R561 include board lock features. The 183-037-113R161 and 183-037-113R171 feature ground straps instead.

Q: Can I use a substitute part with a different flange type in my existing application?

A: Flange compatibility depends on your specific mounting requirements. If your application uses 4-40 threaded mounting holes, the 183-037-113R171, 183-037-113R541, or 183-037-113R561 are suitable. If your application requires an unthreaded flange, the 183-037-113R161 is appropriate. Verify your PCB or mounting surface specifications before selection.
