FCE17B25PC490 D-Sub 25-Position Plug Connector – Equivalent & Substitute Parts

Part Overview

The FCE17B25PC490 is a 25-position D-Sub plug connector manufactured by Amphenol ICC, featuring right-angle solder termination and through-hole mounting. This connector is designed for signal applications requiring a 5A current rating and operates across the temperature range of -40°C to 85°C. The part is active in production and RoHS compliant, making it suitable for modern electronic assemblies where environmental and regulatory compliance are required.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits alternative manufacturers while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

All listed NorComp substitute parts (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561) satisfy the core electrical and mechanical compatibility requirements for the FCE17B25PC490. Selection among these alternatives depends on specific flange feature requirements and mounting constraints:

183-025-113R161: Unthreaded housing flange. Select when panel mounting does not require threaded fastening.

183-025-113R171: Threaded housing flange (4-40). Select for standard board-lock mounting with threaded shell attachment.

183-025-113R181: Mating-side female screwlock (4-40). Select when connector-to-connector locking is required at the mating interface.

183-025-113R531: Threaded housing flange (4-40) with board lock feature. Select for applications requiring both board-level fastening and connector retention.

183-025-113R561: Mating-side female screwlock (4-40) with board lock feature. Select for applications requiring both connector-level locking and board-level retention.

All substitute parts carry ROHS3 compliance, meeting or exceeding the RoHS requirements of the original part. The extended operating temperature range (-55°C to 105°C) of NorComp parts provides additional thermal margin beyond the FCE17B25PC490 specification (-40°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can NorComp 183-025-113R parts directly replace the Amphenol FCE17B25PC490 in existing designs?

A: Yes, provided the flange feature of the selected NorComp part matches the mounting requirements of your application. All substitute parts maintain identical 25-position D-Sub configuration, shell size, backset spacing, current rating, and solder termination. Verify flange type compatibility before substitution.

Q: What is the difference between the various NorComp flange options?

A: Flange features determine how the connector attaches to the PCB or panel. Unthreaded flanges (183-025-113R161) provide basic positioning. Threaded housing flanges (183-025-113R171, 183-025-113R531) allow screw fastening to the shell. Mating-side screwlock flanges (183-025-113R181, 183-025-113R561) provide locking at the connector interface. Board lock features (183-025-113R531, 183-025-113R561) add retention at the PCB level.

Q: Are there differences in contact material between the FCE17B25PC490 and NorComp substitutes?

A: Yes. The FCE17B25PC490 uses phosphor bronze contacts, while all NorComp substitutes use brass contacts. Both materials are gold-plated and suitable for signal applications at 5A. Brass contacts in the NorComp parts provide equivalent electrical performance for this application class.

Q: Does the dielectric material difference affect compatibility?

A: No. The FCE17B25PC490 uses glass-filled thermoplastic, while NorComp parts use polyamide (PA9T) nylon 9T. Both materials meet UL94 V-0 flammability requirements and provide adequate dielectric strength for signal-level applications. Material selection does not impact electrical substitution.

Q: What is the significance of the extended operating temperature range in NorComp parts?

A: NorComp substitutes operate from -55°C to 105°C, compared to the FCE17B25PC490 range of -40°C to 85°C. This extended range provides additional thermal margin and allows use in more demanding environmental conditions without derating. For applications within the original -40°C to 85°C specification, this difference is not operationally significant.

Q: Are all substitute parts in stock?

A: Inventory availability varies. 183-025-113R161 has 1605 units, 183-025-113R171 has 2139 units, 183-025-113R181 has 1140 units, 183-025-113R531 has 1392 units, and 183-025-113R561 has 1661 units available as new original stock. Verify current availability before design commitment.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications restrict hazardous substances in electronic components. ROHS3 represents the current regulatory standard and includes additional substance restrictions beyond the original RoHS directive. NorComp parts with ROHS3 compliance meet or exceed the RoHS requirements of the FCE17B25PC490.
