Engineering Selection Recommendations
NorComp Series 183 Substitutes (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561)
These connectors are direct mechanical and electrical equivalents with ROHS3 compliance certification. All maintain the 0.590" (14.99mm) backset spacing and 5A current rating. Extended operating temperature range (-55°C to 105°C) provides thermal margin beyond the FCE17B25PC450 specification. Selection among NorComp variants depends on flange feature requirements: housing-mounted 4-40 threads (183-025-113R531), mating-side screwlock features (183-025-113R181, 183-025-113R561), or unthreaded housing (183-025-113R161).
TE Connectivity AMPLIMITE Substitutes (205857-1, 5205857-1, 5747022-2)
These parts provide alternative sourcing with elevated current capacity (6A) and explicit voltage rating (125V). Critical design consideration: backset spacing is 0.545" (13.84mm), requiring PCB layout verification before implementation. Part 205857-1 carries RoHS non-compliant status; parts 5205857-1 and 5747022-2 meet ROHS3 requirements. TE Connectivity parts include mounting bracket features and grounding indent provisions.
Compliance Considerations
For applications requiring RoHS compliance, NorComp Series 183 parts and TE Connectivity 5205857-1 and 5747022-2 are qualified. Part 205857-1 is not RoHS compliant and is unsuitable for regulated applications.
Frequently Asked Questions (FAQ)
Q: Can NorComp Series 183 connectors directly replace the FCE17B25PC450 without PCB modification?
A: Yes, for applications using the standard through-hole right-angle mounting configuration. NorComp parts maintain identical backset spacing (0.590" / 14.99mm) and pin count. Flange feature variations (4-40 threads, screwlock, unthreaded) do not affect PCB compatibility if the original design accommodates the selected flange type.
Q: What is the primary limitation when substituting TE Connectivity AMPLIMITE parts?
A: Backset spacing differs at 0.545" (13.84mm) versus the FCE17B25PC450 specification of 0.590" (14.99mm). This 0.045" (1.15mm) difference requires PCB layout verification and potential redesign of mounting hole patterns. Electrical and thermal performance remain compatible.
Q: Are all substitute parts suitable for RoHS-regulated applications?
A: No. Part 205857-1 is RoHS non-compliant. NorComp Series 183 parts (all variants) and TE Connectivity parts 5205857-1 and 5747022-2 meet ROHS3 compliance. Verify regulatory requirements before part selection.
Q: What is the temperature operating range difference between the main part and substitutes?
A: The FCE17B25PC450 operates from -40°C to 85°C. All substitute parts extend this range to -55°C to 105°C, providing additional thermal margin for demanding environments. Applications within the original -40°C to 85°C window are fully compatible with all substitutes.
Q: Do NorComp and TE Connectivity connectors have different contact materials?
A: Yes. The FCE17B25PC450 uses phosphor bronze contacts with gold finish (15.0µin thickness). NorComp Series 183 parts use brass contacts with gold flash finish. TE Connectivity AMPLIMITE parts use brass contacts with gold finish. Contact material differences do not affect signal integrity for standard D-Sub applications but may influence corrosion resistance in specific environments.
Q: Can I mix manufacturers in a single assembly?
A: Yes, provided all selected parts meet the core compatibility criteria: 25-position D-Sub plug configuration, shell size 3 (DB, B), solder termination, and right-angle mounting. Verify backset spacing consistency across the assembly to ensure uniform PCB hole patterns.
Q: What inventory levels are available for each substitute?
A: NorComp 183-025-113R161: 1605 units; 183-025-113R171: 2139 units; 183-025-113R181: 1140 units; 183-025-113R531: 1392 units; 183-025-113R561: 1661 units. TE Connectivity 205857-1: 762 units; 5205857-1: 1015 units; 5747022-2: 1645 units. Inventory levels support high-volume production requirements.
