Engineering Selection Recommendations

All listed substitute parts maintain active product status and UL94 V-0 flammability certification, ensuring regulatory compliance and continued manufacturing support equivalent to the FCE17B25SC25B.

NorComp 183 Series (183-025-213R541, 183-025-213R561, 183-025-213R571): These connectors provide extended operating temperature range (-55°C ~ 105°C) and ROHS3 compliance. The 183-025-213R571 variant offers the highest inventory availability (2006 units) and matches the backset spacing of the FCE17B25SC25B. NorComp parts feature nickel-plated steel shells and board lock functionality. Selection among these three variants depends on specific flange feature requirements: mating side female screwlock (R541, R561) or housing/shell configuration (R571).

TE Connectivity AMPLIMITE Series (5205858-1, 5745114-2, 5745536-2, 5745992-3, 5747838-3, 5747838-4, 5747838-6): TE Connectivity substitutes provide 6A current rating (exceeding the 5A specification) and extended operating temperature range (-55°C ~ 105°C). All variants maintain RoHS compliance and UL94 V-0 certification. The 5745536-2 offers the highest inventory level (5499 units) and features female screwlock mating side configuration. Variants 5747838-3, 5747838-4, and 5747838-6 include board lock and ground strap features. The 5205858-1 features yellow chromate plated zinc shell finish and 125V voltage rating specification. TE Connectivity parts utilize phosphor bronze contacts and are available in tube or bulk packaging.

Backset Spacing Consideration: The TE Connectivity 5205858-1 and 5745114-2 specify 0.545" (13.84mm) backset spacing, which differs from the FCE17B25SC25B specification of 0.590" (14.99mm). All other substitutes maintain the 0.590" (14.99mm) backset spacing.

Frequently Asked Questions (FAQ)

Q: Can I substitute a TE Connectivity part with 6A current rating for the FCE17B25SC25B rated at 5A?

A: Yes. The 6A current rating of TE Connectivity substitutes exceeds the 5A requirement of the FCE17B25SC25B. Higher current ratings provide equivalent or superior performance in applications designed for 5A operation.

Q: What is the significance of the different backset spacing values (0.590" vs 0.545")?

A: Backset spacing defines the distance from the mating face to the solder tail termination points. The FCE17B25SC25B specifies 0.590" (14.99mm). TE Connectivity parts 5205858-1 and 5745114-2 specify 0.545" (13.84mm). This difference affects PCB layout and mounting hole positioning. Verify PCB design compatibility before selecting parts with differing backset spacing.

Q: Are NorComp and TE Connectivity substitutes electrically compatible with the FCE17B25SC25B?

A: Yes. All listed substitutes maintain identical connector type (receptacle, female sockets), position count (25), row configuration (2), and shell size (3 DB, B). All feature solder termination, UL94 V-0 flammability rating, and gold contact finish. Electrical compatibility is established through these matching parameters.

Q: What is the difference between housing/shell flange and mating side flange configurations?

A: Housing/shell flange features threaded mounting holes (4-40) on the connector shell itself. Mating side flange features threaded mounting holes on the mating interface side. The FCE17B25SC25B uses housing/shell configuration. NorComp 183-025-213R571 and TE Connectivity 5745992-3, 5747838-3, 5747838-4 also feature housing/shell configuration. NorComp 183-025-213R541, 183-025-213R561 and TE Connectivity 5747838-6 feature mating side female screwlock configuration. Selection depends on mechanical mounting requirements.

Q: Do all substitutes support the same operating temperature range as the FCE17B25SC25B?

A: No. The FCE17B25SC25B operates from -40°C to 85°C. All NorComp and TE Connectivity substitutes extend this range to -55°C to 105°C. The extended range of substitute parts accommodates applications requiring lower minimum or higher maximum operating temperatures.

Q: What packaging options are available for these substitutes?

A: The FCE17B25SC25B is supplied in standard packaging. NorComp parts are supplied in trays. TE Connectivity parts are supplied in tubes (5747838 series) or bulk packaging (5205858-1, 5745114-2, 5745536-2, 5745992-3). Packaging selection affects handling, storage, and assembly processes.

Q: Are all substitutes RoHS compliant?

A: Yes. The FCE17B25SC25B is RoHS Compliant. NorComp substitutes are ROHS3 Compliant. All TE Connectivity substitutes are RoHS Compliant. Both RoHS and ROHS3 compliance meet current regulatory requirements for restricted substance elimination.

Q: What is the inventory availability for each substitute?

A: Inventory levels are: NorComp 183-025-213R541 (1105 units), 183-025-213R561 (864 units), 183-025-213R571 (2006 units); TE Connectivity 5205858-1 (1300 units), 5745114-2 (1392 units), 5745536-2 (5499 units), 5745992-3 (1532 units), 5747838-3 (3505 units), 5747838-4 (3564 units), 5747838-6 (1011 units). The FCE17B25SC25B maintains 918 units in stock.
