FCE17C37PC650 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The FCE17C37PC650 is a 37-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This right-angle, solder-terminated connector features male pins with a 2-row configuration in shell size 4 (DC, C). The connector is designed for through-hole mounting applications and is currently in active product status with RoHS compliance. Equivalent and substitute parts are necessary when the primary part is unavailable, when alternative flange configurations are required for specific mounting applications, or when alternative contact materials and shell finishes better suit system requirements.

Engineering Selection Recommendations

Primary Substitution Criteria:

All four NorComp 183-series connectors (183-037-113R161, 183-037-113R171, 183-037-113R541, 183-037-113R561) are functionally equivalent to the FCE17C37PC650 for applications requiring a 37-position D-Sub plug connector with solder termination and 5A current capacity. All substitute parts maintain active product status and comply with UL94 V-0 flammability requirements.

Compliance Considerations:

The FCE17C37PC650 carries RoHS Compliant status, while all NorComp substitutes carry ROHS3 Compliant status. Both compliance levels satisfy RoHS directive requirements. The NorComp parts additionally carry REACH Unaffected designation, providing expanded regulatory coverage for European applications.

Flange Feature Selection:

Selection among the four NorComp substitutes depends on the specific flange configuration required by the application:

183-037-113R161: Unthreaded housing/shell flange for applications requiring simple board-level mounting without threaded fastening.
183-037-113R171: 4-40 threaded housing/shell flange for applications requiring threaded fastening to the connector shell.
183-037-113R541: Mating side female screwlock (4-40) for applications requiring mating-side locking mechanisms.
183-037-113R561: Mating side female screwlock (4-40) with identical specifications to 183-037-113R541.

Material and Temperature Considerations:

The NorComp substitutes feature an extended operating temperature range (-55°C ~ 105°C) compared to the FCE17C37PC650 (-40°C ~ 85°C). This extended range provides additional thermal margin for demanding applications. The NorComp parts use brass contact material and polyamide dielectric material, while the Amphenol part uses phosphor bronze contacts and thermoplastic glass-filled dielectric. Both material combinations satisfy the specified current rating and flammability requirements.

Shell Finish Difference:

The FCE17C37PC650 features a tin-plated steel shell, while all NorComp substitutes feature nickel-plated steel shells. Both finishes provide corrosion resistance appropriate for the specified operating environment.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-037-113R161 directly replace the FCE17C37PC650 in all applications?

A: The 183-037-113R161 is electrically and mechanically compatible with the FCE17C37PC650 for applications requiring a 37-position D-Sub plug connector with solder termination. The primary difference is the flange feature configuration. The 183-037-113R161 features an unthreaded housing/shell flange, while the FCE17C37PC650 features an M3 threaded flange. Compatibility depends on whether the application requires threaded fastening to the connector shell.

Q: What is the difference between the 183-037-113R541 and 183-037-113R561?

A: Both parts feature identical electrical and mechanical specifications, including mating side female screwlock (4-40) flange configuration, brass contact material, and polyamide dielectric material. Both parts carry ROHS3 compliance and REACH Unaffected status. The parts are functionally interchangeable.

Q: Does the extended operating temperature range of the NorComp substitutes affect compatibility?

A: The NorComp substitutes operate from -55°C to 105°C, compared to the FCE17C37PC650 operating range of -40°C to 85°C. The extended range of the NorComp parts is a superset of the Amphenol part's range. Applications operating within the FCE17C37PC650 temperature range are fully compatible with NorComp substitutes. Applications requiring operation below -40°C or above 85°C require the NorComp substitutes.

Q: Are there differences in contact material between the main part and substitutes?

A: The FCE17C37PC650 uses phosphor bronze contacts, while all NorComp substitutes use brass contacts. Both materials are gold-finished and rated for 5A current. The contact material difference does not affect electrical performance for the specified current rating and signal applications.

Q: What packaging format is used for the NorComp substitutes?

A: All four NorComp substitute parts are supplied in tray packaging. The FCE17C37PC650 packaging format is not specified in the provided data.

Q: How do I select the correct NorComp substitute based on flange requirements?

A: Determine the flange configuration required by your application: (1) If no threaded fastening to the connector shell is required, select 183-037-113R161 with unthreaded housing/shell flange; (2) If threaded fastening to the connector shell is required using 4-40 threads, select 183-037-113R171 with 4-40 threaded housing/shell flange; (3) If mating-side locking is required, select either 183-037-113R541 or 183-037-113R561, both featuring mating side female screwlock (4-40) configuration.

Q: Are all substitute parts RoHS compliant?

A: Yes. The FCE17C37PC650 carries RoHS Compliant status. All four NorComp substitutes carry ROHS3 Compliant status. Both compliance levels satisfy RoHS directive requirements. The NorComp parts additionally carry REACH Unaffected designation.

Q: What is the significance of the shell finish difference between tin plating and nickel plating?

A: The FCE17C37PC650 features tin-plated steel shell, while NorComp substitutes feature nickel-plated steel shell. Both finishes provide corrosion resistance. Nickel plating offers enhanced corrosion resistance in certain chemical environments and is commonly used in industrial applications. Tin plating is suitable for standard operating environments. Selection depends on the specific environmental exposure of the application.
