Engineering Selection Recommendations

Primary Substitute: FCE17B25SN440 (Amphenol ICC)

The FCE17B25SN440 is the recommended primary substitute for the obsolete FCC17B25SN440. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications. The FCE17B25SN440 is in active product status with RoHS Compliant certification, making it suitable for new designs and legacy system replacements. Inventory availability is confirmed at 742 pieces.

Secondary Substitutes: NorComp Inc. 172-025 Series

The NorComp Inc. 172-025 series (172-025-283L001, 172-025-283L011, 172-025-283L021, 172-025-283L031) provides cross-manufacturer alternatives with extended operating temperature ranges (-50°C ~ 125°C) and ROHS3 Compliant certification. These parts feature panel mount capability in addition to through-hole mounting, offering design flexibility. Selection among these variants depends on flange feature requirements:

172-025-283L001: Housing/Shell (Unthreaded) flange
172-025-283L011: Board Side (4-40) flange
172-025-283L021: Board Side (4-40) flange
172-025-283L031: Mating Side (4-40) flange

Tertiary Substitutes: TE Connectivity AMPLIMITE HDP-20 Series

The TE Connectivity 205738 and 5205738 series connectors provide alternatives with 6A current rating (exceeding the 5A requirement) and extended operating temperature ranges (-55°C ~ 105°C). The 5205738-1 and 5205738-3 variants offer ROHS3 Compliant or RoHS Compliant status. These parts feature Housing/Shell (Unthreaded) flange configuration. The 205738-3 and 205738-7 variants are RoHS non-compliant, matching the compliance status of the original FCC17B25SN440.

Compliance Considerations:

For applications requiring RoHS compliance, select FCE17B25SN440, NorComp 172-025 series, or TE Connectivity 5205738-1 and 5205738-3. For legacy systems where RoHS non-compliance is acceptable, 205738-3 and 205738-7 provide direct electrical equivalence with higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25SN440 directly replace FCC17B25SN440 in existing designs?

A: Yes. The FCE17B25SN440 shares identical electrical and mechanical specifications with the FCC17B25SN440, including 25 positions, 2-row configuration, shell size 3 (DB, B), 5A current rating, 200V voltage rating, and -40°C ~ 85°C operating temperature range. The primary difference is product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant).

Q: What is the difference between the NorComp 172-025 variants?

A: All NorComp 172-025 variants (172-025-283L001, 172-025-283L011, 172-025-283L021, 172-025-283L031) share identical electrical specifications but differ in flange feature configuration. The flange feature determines mounting orientation and mechanical interface: Housing/Shell (Unthreaded) for 172-025-283L001, Board Side (4-40) for 172-025-283L011 and 172-025-283L021, and Mating Side (4-40) for 172-025-283L031. Select based on your PCB layout and mechanical mounting requirements.

Q: Are TE Connectivity 205738 and 5205738 series interchangeable?

A: The 205738 and 5205738 series are electrically compatible substitutes with identical connector specifications. The primary differences are RoHS compliance status and dielectric material composition. The 205738 series (205738-3, 205738-7) is RoHS non-compliant with PBT glass-filled dielectric. The 5205738 series (5205738-1, 5205738-3) offers RoHS compliance options with polyamide (PA) nylon glass-filled dielectric. Both series provide 6A current rating and -55°C ~ 105°C operating temperature range.

Q: Can I use a substitute with higher current rating (6A vs. 5A)?

A: Yes. Substitutes with 6A current rating (TE Connectivity 205738 and 5205738 series) are acceptable for applications designed for 5A operation. The higher current rating provides additional safety margin and does not compromise compatibility with 5A-rated circuits.

Q: What mounting type differences exist among substitutes?

A: The FCC17B25SN440 and most substitutes feature through-hole mounting. The NorComp 172-025 series offers dual mounting capability (Panel Mount, Through Hole), providing design flexibility for panel-mounted or PCB-mounted applications. TE Connectivity variants feature through-hole mounting only. Select based on your mechanical assembly requirements.

Q: Are there RoHS compliance implications for substitute selection?

A: Yes. The original FCC17B25SN440 is RoHS non-compliant. For new designs or systems requiring RoHS compliance, select FCE17B25SN440, NorComp 172-025 series (ROHS3 Compliant), or TE Connectivity 5205738-1 and 5205738-3 (ROHS3 or RoHS Compliant). For legacy system maintenance where RoHS compliance is not required, all substitutes are acceptable.

Q: What is the inventory status of substitute parts?

A: Current inventory availability is confirmed as follows: FCE17B25SN440 (742 pcs), 172-025-283L001 (1307 pcs), 172-025-283L011 (740 pcs), 172-025-283L021 (884 pcs), 172-025-283L031 (1043 pcs), 205738-3 (1048 pcs), 205738-7 (917 pcs), 5205738-1 (815 pcs), 5205738-3 (934 pcs). All substitutes are available in new original condition.
