Engineering Selection Recommendations

Primary Recommendation: FCE17C37SN440

The FCE17C37SN440 from Amphenol ICC represents the direct active equivalent to the obsolete FCC17C37SN440. Both parts share identical connector geometry, pin configuration, mounting interface, and electrical ratings. The FCE17 series maintains the same board-side flange mounting with 4-40 fastening. The primary distinction is RoHS compliance status: FCE17C37SN440 is RoHS compliant, whereas the original FCC17C37SN440 is non-compliant. The dielectric material is upgraded to glass-filled thermoplastic in the FCE17 variant. Current inventory of 921 units supports immediate availability.

Secondary Recommendation: NorComp 172 Series (172-037-283L011 or 172-037-283L021)

The NorComp 172-037-283L011 and 172-037-283L021 connectors provide cross-manufacturer alternatives with full ROHS3 compliance and extended operating temperature range (-50°C to 125°C). Both parts maintain 37-position configuration, 5A current rating, and board-side flange mounting. The 172-037-283L011 and 172-037-283L021 are functionally equivalent, with flange feature differences. NorComp parts utilize PBT dielectric material and nickel-plated steel shells. These alternatives are suitable for applications requiring enhanced environmental specifications and regulatory compliance.

Tertiary Recommendation: TE Connectivity AMPLIMITE Series (747315-1 or 5747315-1)

The TE Connectivity 747315-1 and 5747315-1 connectors from the AMPLIMITE HD-20 and AMPLIMITE HD-20 series offer board-side flange mounting compatible with the original FCC17C37SN440 interface. Both parts provide 6A current rating and 125V voltage specification, exceeding the original 5A/200V ratings. The 5747315-1 variant includes RoHS compliance certification. Operating temperature range extends to -55°C to 105°C. These parts are suitable for applications where higher current capacity and compliance certifications are required.

Flange Feature Considerations:

Board Side (4-40): FCE17C37SN440, 172-037-283L011, 172-037-283L021, 747315-1, 5747315-1 provide direct mechanical compatibility with original mounting interface
Housing/Shell (Unthreaded): 172-037-283L001, 745189-7, 5745189-1, 5745189-7 require alternative mounting provisions

Compliance Status:

For applications requiring RoHS compliance, select FCE17C37SN440, 5745189-1, 5745189-7, 5747315-1, or NorComp 172 series variants. The original FCC17C37SN440 and TE Connectivity 745189-7 are non-compliant and unsuitable for regulated markets.

Frequently Asked Questions (FAQ)

Q1: Can FCE17C37SN440 directly replace FCC17C37SN440 without PCB modification?

Yes. The FCE17C37SN440 maintains identical connector geometry, pin pitch, and board-side flange mounting with 4-40 fastening. No PCB layout changes are required. The primary difference is RoHS compliance status and dielectric material composition (glass-filled thermoplastic versus standard thermoplastic).

Q2: What is the significance of flange feature differences (Board Side vs. Housing/Shell)?

Flange feature determines the mechanical mounting interface. Board-side flange (4-40) mounts directly to the PCB with fasteners through the connector shell. Housing/shell unthreaded flange requires alternative mounting provisions such as panel-mount brackets or cable-side retention. Parts with different flange features are not mechanically interchangeable without redesign.

Q3: Are NorComp 172 series connectors electrically compatible with the FCC17C37SN440?

Yes. NorComp 172-037-283L011, 172-037-283L021, and 172-037-283L031 maintain 37-position configuration, 5A current rating, and gold-plated contacts. Electrical compatibility is confirmed. Mechanical compatibility depends on flange feature: 172-037-283L011 and 172-037-283L021 feature board-side (4-40) mounting identical to the original. 172-037-283L031 features mating-side flange and requires mechanical redesign.

Q4: Why do TE Connectivity AMPLIMITE parts specify 6A current rating versus the original 5A?

The 6A rating reflects enhanced contact design and material specifications in the AMPLIMITE series. Parts with higher current ratings are backward-compatible with lower-current applications. The 6A rating does not affect compatibility with 5A circuit designs.

Q5: What is the impact of operating temperature range differences?

The original FCC17C37SN440 operates -40°C to 85°C. NorComp 172 series extends to -50°C to 125°C, and TE Connectivity AMPLIMITE series to -55°C to 105°C. Extended temperature ranges provide additional design margin for thermal environments. Parts with wider temperature ranges are suitable for applications within the original specification range.

Q6: Is voltage rating downgrade from 200V to 125V acceptable?

Voltage rating downgrade is not recommended. The original FCC17C37SN440 specifies 200V. TE Connectivity AMPLIMITE parts specify 125V. For applications requiring 200V isolation or dielectric strength, select FCE17C37SN440 or NorComp 172 series, which do not specify voltage derating. Verify circuit voltage requirements before selecting 125V-rated alternatives.

Q7: What packaging format differences exist among substitute parts?

FCC17C37SN440 and FCE17C37SN440 are supplied in standard packaging. NorComp 172 series is supplied in trays. TE Connectivity AMPLIMITE series is supplied in tubes. Packaging format does not affect electrical or mechanical performance. Verify packaging compatibility with assembly equipment and logistics requirements.

Q8: Are all substitute parts available in current inventory?

Yes. All listed substitute parts maintain active production status with confirmed inventory: FCE17C37SN440 (921 units), NorComp 172-037-283L001 (1006 units), 172-037-283L011 (1121 units), 172-037-283L021 (1106 units), 172-037-283L031 (836 units), TE Connectivity 745189-7 (2246 units), 747315-1 (832 units), 5745189-1 (1164 units), 5745189-7 (1761 units), 5747315-1 (1034 units).

Q9: Which substitute part provides the best RoHS compliance and environmental rating?

NorComp 172 series (all variants) and TE Connectivity 5745189-7 and 5747315-1 provide full RoHS3 compliance. NorComp parts additionally carry REACH Unaffected certification. For applications requiring maximum regulatory compliance, select NorComp 172-037-283L011 or 172-037-283L021 with board-side flange mounting.

Q10: Can substitute parts with different contact materials (Brass vs. Phosphor Bronze) be used interchangeably?

Contact material differences (brass in NorComp parts versus phosphor bronze in Amphenol and TE Connectivity parts) do not affect electrical compatibility within the specified current and voltage ratings. Both materials provide adequate conductivity and contact reliability. Selection may be based on availability, cost, and specific environmental requirements.
