Engineering Selection Recommendations

Primary Substitute: FCE17B25SN400

The FCE17B25SN400 from Amphenol ICC is the direct equivalent to the FCC17B25SN400. Both connectors share identical electrical and mechanical specifications, including 25-position configuration, through-hole solder termination, 5A current rating, and UL94 V-0 flammability rating. The FCE17B25SN400 is currently in active production status, ensuring long-term availability and supply chain continuity. This part is the preferred substitute for direct replacement applications.

Secondary Substitutes: NorComp 172-025 Series

The NorComp 172-025-283L001, 172-025-283L011, 172-025-283L021, and 172-025-283L031 connectors provide electrical compatibility with enhanced operating temperature range (-50°C to 125°C versus -40°C to 85°C). These parts feature panel-mount and through-hole mounting configurations with board-side or mating-side flange options. All maintain 25-position, 5A current rating, and UL94 V-0 compliance. The NorComp series is ROHS3 compliant, offering regulatory advantage over the non-compliant FCC17B25SN400. Selection among the four variants depends on specific flange feature requirements for the application.

Tertiary Substitutes: TE Connectivity AMPLIMITE HDP-20 Series

The 205738-3, 205738-7, 5205738-1, and 5205738-3 connectors from TE Connectivity provide functional equivalence with enhanced current rating (6A versus 5A) and extended operating temperature range (-55°C to 105°C). These parts feature through-hole solder termination and 25-position configuration. The 5205738-1 and 5205738-3 variants are ROHS3 compliant, while 205738-3 and 205738-7 are non-compliant. Voltage rating is specified at 125V, which is lower than the original 200V specification; however, this does not preclude substitution in applications operating below 125V.

Compliance Considerations:

For applications requiring RoHS compliance, the FCE17B25SN400, NorComp 172-025 series, and TE Connectivity 5205738-1 and 5205738-3 are compliant alternatives. The original FCC17B25SN400 and TE Connectivity 205738-3 and 205738-7 are non-compliant.

Frequently Asked Questions (FAQ)

Q: Can the FCE17B25SN400 be used as a direct replacement for the FCC17B25SN400?

A: Yes. The FCE17B25SN400 is electrically and mechanically equivalent to the FCC17B25SN400. Both are 25-position D-Sub receptacles with through-hole solder termination, 5A current rating, and UL94 V-0 flammability rating. The FCE17B25SN400 is in active production, making it the preferred substitute.

Q: What is the difference between the NorComp 172-025 variants (283L001, 283L011, 283L021, 283L031)?

A: The primary difference among these four NorComp parts is the flange feature configuration. The 283L001 features a housing/shell unthreaded flange, 283L011 and 283L021 feature board-side 4-40 flanges, and 283L031 features a mating-side 4-40 flange. All four maintain identical electrical specifications and are suitable substitutes where the mounting configuration is compatible with the application.

Q: Are the TE Connectivity AMPLIMITE HDP-20 series parts suitable for applications requiring 200V operation?

A: The TE Connectivity 205738-3, 205738-7, 5205738-1, and 5205738-3 are rated for 125V operation. These parts are not suitable for applications requiring 200V operation. The FCE17B25SN400 or NorComp 172-025 series should be selected for 200V applications, as these parts do not specify a voltage limitation that would preclude 200V operation.

Q: What is the temperature operating range difference between the original part and the substitutes?

A: The FCC17B25SN400 operates from -40°C to 85°C. The NorComp 172-025 series extends this range to -50°C to 125°C. The TE Connectivity AMPLIMITE HDP-20 series operates from -55°C to 105°C. All substitute parts encompass the original operating range, making them suitable for applications within the original temperature specification.

Q: Are there RoHS compliance differences among the substitute parts?

A: Yes. The FCE17B25SN400 is RoHS compliant. The NorComp 172-025 series is ROHS3 compliant. The TE Connectivity 5205738-1 and 5205738-3 are RoHS compliant. The TE Connectivity 205738-3 and 205738-7 are non-compliant. For applications requiring RoHS compliance, select from the compliant alternatives.

Q: What is the difference between through-hole and panel-mount configurations?

A: Through-hole mounting (FCC17B25SN400, FCE17B25SN400, TE Connectivity series) involves inserting the connector leads directly into printed circuit board holes for solder termination. Panel-mount configurations (NorComp 172-025 series) include a flange that mounts to a panel or enclosure, with leads extending through the panel for solder termination on the rear side. Panel-mount variants are suitable for applications requiring front-panel connector access.

Q: Can the NorComp 172-025 series be used in applications designed for the original FCC17B25SN400?

A: The NorComp 172-025 series provides electrical compatibility but features panel-mount capability in addition to through-hole termination. If the application requires board-side mounting without panel access, the through-hole variants (FCE17B25SN400 or TE Connectivity series) are more appropriate. If panel-mount capability is acceptable or required, the NorComp series is suitable.

Q: What is the current rating difference between the original part and TE Connectivity substitutes?

A: The FCC17B25SN400 is rated for 5A. The TE Connectivity AMPLIMITE HDP-20 series (205738-3, 205738-7, 5205738-1, 5205738-3) is rated for 6A. The higher current rating of the TE Connectivity parts provides additional margin and is suitable for applications designed for 5A operation.

Q: Are contact material differences significant for substitution?

A: The FCC17B25SN400 uses Phosphor Bronze contacts. The NorComp 172-025 series uses Brass contacts. The TE Connectivity AMPLIMITE HDP-20 series uses Phosphor Bronze contacts. Both Phosphor Bronze and Brass are acceptable contact materials for D-Sub connectors and do not preclude substitution. Contact finish (gold plating) is consistent across all parts.
