Engineering Selection Recommendations

All substitute parts listed maintain active production status and comply with RoHS or ROHS3 regulations, ensuring long-term availability and environmental compliance. The NorComp 183 series alternatives provide extended operating temperature ranges (-55°C to 105°C) compared to the original FCE17B25PC680 (-40°C to 85°C), offering broader thermal performance margins for demanding applications.

Selection by Flange Configuration:

183-025-113R161: Unthreaded housing/shell flange. Select when panel mounting requires no threaded engagement.
183-025-113R171: Housing/shell with 4-40 threaded flange. Select for standard panel mount applications requiring mechanical fastening.
183-025-113R181: Mating-side female screwlock (4-40). Select when connector retention and secure mating are critical design requirements.
183-025-113R531: Housing/shell with 4-40 threaded flange and board lock feature. Select for applications requiring both panel mounting and PCB-level retention.
183-025-113R561: Mating-side female screwlock (4-40) with board lock feature. Select for maximum mechanical security combining both panel and board-level locking mechanisms.

All substitute parts are electrically and mechanically compatible with the FCE17B25PC680 within the specified parameter envelope. Selection should be based on the specific flange and locking feature requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183 series connectors directly replace the Amphenol FCE17B25PC680?

A: Yes, all listed NorComp 183 series parts (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561) are functionally equivalent to the FCE17B25PC680. They share identical electrical specifications (25 positions, 2 rows, 5A current rating, 0.590" backset spacing), mechanical mounting (through-hole, right-angle), and connector geometry (shell size 3, DB/B layout). Selection depends on flange configuration requirements specific to your application.

Q: What are the differences between the five NorComp substitute options?

A: The five NorComp alternatives differ in flange feature configuration: 183-025-113R161 has an unthreaded housing/shell; 183-025-113R171 and 183-025-113R531 feature 4-40 threaded housing/shell flanges; 183-025-113R181 and 183-025-113R561 include mating-side female screwlock (4-40) mechanisms. Additionally, 183-025-113R531 and 183-025-113R561 incorporate board lock features for enhanced PCB retention.

Q: Are there any material or finish differences that affect compatibility?

A: The FCE17B25PC680 uses phosphor bronze contacts with tin-plated steel shell, while all NorComp substitutes use brass contacts with nickel-plated steel shell. Both contact materials and finishes are acceptable for signal applications and maintain equivalent electrical performance. Gold contact finish is consistent across all parts.

Q: What is the operating temperature difference, and does it matter?

A: The FCE17B25PC680 operates from -40°C to 85°C, while all NorComp substitutes operate from -55°C to 105°C. The extended range of the substitutes encompasses the original specification, providing additional thermal margin. This difference does not prevent substitution; it represents an improvement in thermal capability.

Q: Do all substitute parts have the same RoHS compliance status?

A: The FCE17B25PC680 is RoHS Compliant. All NorComp substitutes are ROHS3 Compliant, which represents an updated compliance standard. Both statuses satisfy RoHS requirements and are acceptable for equivalent substitution.

Q: Which substitute should I select for a panel-mount application?

A: For standard panel mounting without additional locking requirements, select 183-025-113R171 (4-40 threaded housing/shell). For applications requiring secure mating with screwlock retention, select 183-025-113R181 (mating-side female screwlock). For combined panel and board-level security, select 183-025-113R561 (screwlock with board lock).

Q: Are the packaging specifications different between the main part and substitutes?

A: The FCE17B25PC680 packaging is not specified in the provided data. All NorComp substitutes are supplied in Tray packaging. Confirm packaging requirements with your procurement process before finalizing part selection.

Q: Can I use these substitutes interchangeably within the same design?

A: Substitutes can be used interchangeably only if your PCB layout and mechanical design accommodate the specific flange configuration of the selected part. Verify that mounting holes, panel cutouts, and connector retention mechanisms align with the chosen substitute's flange feature before implementation.
