Engineering Selection Recommendations

Amphenol ICC Series (FCE17C37SN490): This part maintains identical electrical and mechanical specifications to the FCC17C37SN490 while offering active product status and RoHS compliance. The FCE17 series represents the direct successor within the Amphenol ICC product line and is the preferred substitute for new designs and obsolescence mitigation.

NorComp 172 Series (172-037-283L011, 172-037-283L021): These parts provide 37-position D-Sub receptacle functionality with board-side flange mounting, matching the FCC17C37SN490 configuration. Both parts are ROHS3 compliant and active. The extended operating temperature range (-50°C to 125°C) exceeds the original specification. Nickel-plated steel shells and brass contacts differ from the original tin-plated steel and phosphor bronze, but remain within acceptable D-Sub 37-position receptacle parameters. The 172-037-283L031 variant features mating-side flange mounting and is not recommended for direct substitution due to flange position incompatibility.

TE Connectivity AMPLIMITE Series (747315-1, 5747315-1): These parts feature board-side flange mounting with 6A current rating and 125V voltage specification, exceeding the original 5A/200V ratings. The 747315-1 carries no RoHS designation, while 5747315-1 is RoHS compliant. Both are active products suitable for applications where higher current capacity is acceptable.

TE Connectivity AMPLIMITE Series (745189-7, 5745189-7, 5745189-1): These parts feature housing/shell unthreaded flange configuration, differing from the board-side mounting of the FCC17C37SN490. The 5745189-7 offers RoHS compliance and active status. These variants are suitable only where flange position flexibility exists in the mechanical design.

For new designs and obsolescence replacement, FCE17C37SN490 is the primary recommendation. For applications requiring RoHS compliance with extended temperature range, NorComp 172-037-283L011 or 172-037-283L021 are acceptable alternatives. TE Connectivity parts are suitable where higher current ratings and active product status are prioritized.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SN490 directly replace FCC17C37SN490 in existing designs?

A: Yes. The FCE17C37SN490 maintains identical electrical specifications (5A, 200V unspecified in substitute data), mechanical configuration (37-position, board-side flange, through-hole solder termination), and physical form factor. The primary difference is active product status and RoHS compliance, making it a direct substitute.

Q: What is the difference between board-side and housing/shell flange mounting?

A: Board-side flange (4-40) mounting positions the flange on the connector body facing the PCB, with threaded holes for mechanical retention. Housing/shell unthreaded flange mounting positions the flange on the connector shell without threaded retention points. These configurations are mechanically incompatible and require different PCB layouts. Verify your mechanical design before selecting a substitute with different flange positioning.

Q: Are NorComp 172 series parts compatible with the original FCC17C37SN490 footprint?

A: NorComp 172-037-283L011 and 172-037-283L021 maintain 37-position D-Sub receptacle configuration with board-side flange mounting, matching the FCC17C37SN490 mechanical interface. However, contact material differs (brass vs. phosphor bronze) and shell finish differs (nickel vs. tin plating). Electrical performance remains within D-Sub 37-position specifications. Verify mating connector compatibility before implementation.

Q: What is the significance of RoHS compliance in substitute selection?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. The original FCC17C37SN490 is RoHS non-compliant. For applications subject to RoHS requirements, FCE17C37SN490, NorComp 172 series (ROHS3 compliant), or TE Connectivity 5745189-7 and 5747315-1 (RoHS compliant) are required.

Q: Can TE Connectivity AMPLIMITE parts substitute for the FCC17C37SN490?

A: TE Connectivity parts are functionally compatible as 37-position D-Sub receptacles with solder termination and gold-plated contacts. However, they feature higher current ratings (6A vs. 5A) and lower voltage ratings (125V vs. 200V). Flange configuration varies by part number. These parts are suitable for applications where the higher current capacity is acceptable and voltage requirements do not exceed 125V. Verify electrical requirements before selection.

Q: What packaging differences exist among substitute parts?

A: FCC17C37SN490 and FCE17C37SN490 are supplied in standard packaging. NorComp 172 series parts are supplied in trays. TE Connectivity AMPLIMITE parts are supplied in tubes. Packaging differences do not affect electrical or mechanical compatibility but may impact inventory management and handling procedures.

Q: Is the extended operating temperature range of NorComp parts a concern?

A: No. NorComp 172 series parts operate from -50°C to 125°C, exceeding the original -40°C to 85°C specification. Extended temperature range provides additional design margin and is not a compatibility issue. Applications operating within the original temperature range experience no adverse effects.
