Engineering Selection Recommendations

For Direct Replacement (Identical Mounting Configuration):

FCE17B25SN280 is the primary recommended substitute. This Amphenol ICC part maintains identical electrical and mechanical specifications to the FCC17B25SN280 while offering active product status and RoHS compliance. The FCE17 series represents the current-generation equivalent within the same manufacturer's product line.

For RoHS Compliance Requirements:

5205738-3 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20 series) provides RoHS compliance with active product status. This part exceeds the original voltage rating (125V vs. 200V specification) and current rating (6A vs. 5A), supporting broader application compatibility. Operating temperature range extends to -55°C ~ 105°C, exceeding the original -40°C ~ 85°C specification.

5205738-1 offers identical electrical and mechanical characteristics to 5205738-3 with ROHS3 compliance and active status, differentiated by packaging (Bulk vs. Tube).

For Panel Mount Applications:

The NorComp Inc. 172-025 series (172-025-283L001, 172-025-283L011, 172-025-283L021, 172-025-283L031) provides panel mount through-hole capability with ROHS3 compliance and active product status. Selection among these variants depends on flange feature requirements:

172-025-283L001: Unthreaded housing/shell flange (closest to original mounting style)
172-025-283L011 and 172-025-283L021: Board-side 4-40 threaded flange
172-025-283L031: Mating-side 4-40 threaded flange

For Legacy Non-Compliant Applications:

205738-3 and 205738-7 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20 series) maintain RoHS non-compliant status matching the original part, with active product availability and enhanced electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25SN280 be used as a direct replacement for FCC17B25SN280?

A: Yes. FCE17B25SN280 maintains identical connector type, position count, row configuration, shell size, mounting type, termination method, current rating, and operating temperature range. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (Compliant vs. non-compliant). Both are Amphenol ICC products with compatible electrical and mechanical specifications.

Q: What is the difference between the TE Connectivity 205738 and 5205738 series?

A: Both series are AMPLIMITE HDP-20 D-Sub receptacles with identical electrical and mechanical specifications (25 positions, 2 rows, Shell Size 3, 6A current rating, 125V voltage rating, -55°C ~ 105°C operating range). The primary distinction is RoHS compliance status: 205738 series is RoHS non-compliant, while 5205738 series is ROHS3 compliant. Packaging differs between variants (Bulk, Tube).

Q: Are NorComp 172-025 series connectors compatible with the original FCC17B25SN280 mounting?

A: NorComp 172-025 series connectors are functionally equivalent in electrical specifications and connector configuration (25 positions, 2 rows, Shell Size 3, 5A current rating, solder termination). However, they feature panel mount through-hole capability with alternative flange options (unthreaded housing, board-side 4-40, or mating-side 4-40), whereas the original FCC17B25SN280 is vertical through-hole with unthreaded housing. Selection depends on specific mounting requirements.

Q: What is the significance of the flange feature differences in the 172-025 series?

A: Flange feature determines the mechanical mounting interface. 172-025-283L001 features unthreaded housing/shell flange, providing the closest mechanical compatibility to the original FCC17B25SN280. 172-025-283L011 and 172-025-283L021 feature board-side 4-40 threaded flanges for panel-mount applications with fastening on the circuit board side. 172-025-283L031 features mating-side 4-40 threaded flange for fastening on the connector mating side. Selection depends on available mounting space and fastening requirements.

Q: Does the voltage rating difference between FCC17B25SN280 (200V) and substitute parts affect compatibility?

A: Substitute parts with lower voltage ratings (125V for TE Connectivity series, unspecified for Amphenol FCE17 and NorComp 172-025 series) are suitable for applications operating at or below their rated voltage. For applications requiring 200V operation, verify that the substitute part's voltage rating meets or exceeds the application requirement. Unspecified voltage ratings in active products typically indicate general-purpose industrial ratings suitable for standard signal applications.

Q: What packaging options are available for substitute parts?

A: Packaging varies by manufacturer and part number. Amphenol FCE17B25SN280 is supplied in standard packaging. TE Connectivity 205738 series is supplied in Bulk packaging, while 5205738-1 is supplied in Bulk and 5205738-3 is supplied in Tube. NorComp 172-025 series is supplied in Tray packaging. Packaging selection affects quantity per container and handling requirements but does not affect electrical or mechanical compatibility.

Q: Are there compliance differences between substitute options?

A: Yes. FCC17B25SN280 is RoHS non-compliant. FCE17B25SN280 is RoHS Compliant. TE Connectivity 205738 series is RoHS non-compliant, while 5205738 series is ROHS3 Compliant. NorComp 172-025 series is ROHS3 Compliant. For applications requiring RoHS compliance, select from FCE17B25SN280, 5205738-1, 5205738-3, or NorComp 172-025 variants. For legacy applications permitting non-compliant components, 205738 series remains available.
