- Housing/shell flange (M3 or 4-40): Direct mounting to connector housing
- Mating side female screwlock (4-40): Mating connector attachment
- Mating side standard screws (4-40): Standard screw attachment
The FCE17B25SC640 specifies housing/shell (M3) flange. Equivalent parts with housing/shell (4-40) flange include 183-025-213R571, 5745992-3, 5747838-3, 5747838-4, and 5747838-6.
Frequently Asked Questions (FAQ)
Q: Can I substitute a NorComp 183 series connector for the FCE17B25SC640?
A: Yes. NorComp 183 series connectors (183-025-213R541, 183-025-213R561, 183-025-213R571) are functionally equivalent. All maintain 25-position, 2-row DB/B shell configuration with solder termination and gold contact finish. The 183-025-213R571 is specifically listed as a direct substitute. Differences include nickel-plated steel shells versus tin-plated, brass contacts versus phosphor bronze, and extended operating temperature range (-55°C to 105°C). Panel mount capability is an additional feature of NorComp parts.
Q: What is the difference between TE Connectivity AMPLIMITE HDP-20 and HD-20 series?
A: Both series maintain the same 25-position, 2-row DB/B shell configuration with solder termination. The primary differences are in backset spacing and feature set. HDP-20 series (5205858-1, 5745114-2) feature 0.545" backset spacing. HD-20 series (5745536-2, 5745992-3, 5747838-3, 5747838-4, 5747838-6) feature 0.590" backset spacing and include additional features such as board lock, ground strap, and mounting brackets. The 0.590" backset spacing of HD-20 series matches the FCE17B25SC640 specification.
Q: Does backset spacing affect compatibility?
A: Backset spacing is the distance from the rear of the connector shell to the solder cup termination points. The FCE17B25SC640 specifies 0.590" (14.99mm). TE Connectivity HDP-20 series parts specify 0.545" (13.84mm). This 0.045" difference affects PCB layout and mounting hole positioning. If PCB layout is fixed, backset spacing must match. TE Connectivity HD-20 series and NorComp 183 series parts maintain 0.590" backset spacing and are compatible with existing PCB designs.
Q: Are all substitute parts RoHS compliant?
A: Yes. The FCE17B25SC640 is RoHS compliant. All substitute parts listed are either RoHS compliant or ROHS3 compliant. ROHS3 represents the current RoHS directive implementation and is fully compatible with RoHS compliant applications.
Q: What is the difference between tin-plated and nickel-plated shells?
A: Shell plating affects corrosion resistance and environmental performance. Tin plating provides good solderability and corrosion resistance in standard environments. Nickel plating provides enhanced corrosion resistance in harsh or marine environments. Both finishes are acceptable for standard industrial applications. The FCE17B25SC640 uses tin plating. NorComp 183 series uses nickel plating. TE Connectivity AMPLIMITE series uses tin plating (except 5205858-1 which uses yellow chromate plated zinc).
Q: Can I use a connector with 6A current rating in place of a 5A rated connector?
A: Yes. A connector with higher current rating can be substituted for one with lower current rating. The 6A rated TE Connectivity AMPLIMITE series parts are suitable for applications designed for 5A operation. The higher current rating provides additional margin and does not affect compatibility or performance in 5A applications.
Q: What is the significance of the contact finish thickness specification?
A: Contact finish thickness affects contact durability and wear resistance. The FCE17B25SC640 specifies 15.0µin (0.38µm) gold plating. TE Connectivity parts 5747838-4 and 5747838-6 specify 30.0µin (0.76µm), providing double the plating thickness. NorComp and other TE Connectivity parts specify flash plating. Thicker plating provides extended contact life in high-cycle mating applications. All specifications are acceptable for standard signal applications.
Q: Are there packaging differences among substitute parts?
A: Yes. The FCE17B25SC640 is supplied in standard packaging (not specified). NorComp 183 series parts are supplied in tray packaging. TE Connectivity AMPLIMITE HDP-20 series parts are supplied in bulk packaging. TE Connectivity AMPLIMITE HD-20 series parts are supplied in bulk or tube packaging. Packaging affects handling, storage, and component count per shipment but does not affect electrical or mechanical performance.
Q: Which substitute part is the closest match to the FCE17B25SC640?
A: The TE Connectivity 5747838-3 and 5747838-6 are listed as direct substitutes in the FCE17B25SC640 documentation. Both maintain 0.590" backset spacing, tin-plated steel shells, phosphor bronze contacts, housing/shell (4-40) flange configuration, and board lock features. The primary differences are enhanced current rating (6A versus 5A), extended operating temperature range (-55°C to 105°C versus -40°C to 85°C), and 125V voltage rating. The NorComp 183-025-213R571 is also listed as a direct substitute and maintains identical backset spacing and flange configuration.
Q: Can I mix different substitute parts in the same assembly?
A: All listed substitute parts are functionally equivalent and maintain the same 25-position, 2-row DB/B shell configuration with solder termination. Mixing different manufacturers or variants in the same assembly is acceptable from an electrical and mechanical standpoint. However, assembly consistency and traceability practices may require using a single part number throughout a production run.
