Engineering Selection Recommendations

Primary Substitute (Direct Replacement):

FCE17C37SN480 (Amphenol ICC, FCE17 series) is the primary active equivalent. This part maintains identical mounting configuration (Through Hole, Board Side 4-40 flange), electrical ratings (5A, 200V equivalent capability), and operating temperature range (-40°C ~ 85°C). The FCE17 series represents the active production variant of the FCC17 series. RoHS compliance status differs, with FCE17C37SN480 being RoHS compliant, making it suitable for new designs subject to RoHS requirements.

Secondary Substitutes (Amphenol ICC Family):

No additional Amphenol ICC variants maintain the identical board-side flange configuration with matching electrical specifications.

Tertiary Substitutes (TE Connectivity AMP Connectors):

5747315-1 and 747315-1 (AMPLIMITE HD-20 series, TE Connectivity) provide functional equivalence with board-side (4-40) flange mounting. These parts feature higher current ratings (6A versus 5A) and lower voltage ratings (125V versus 200V). Operating temperature range extends to -55°C ~ 105°C. 5747315-1 carries RoHS compliance; 747315-1 status is not applicable. Both are suitable where the reduced voltage rating and extended temperature range do not conflict with application requirements.

Alternative Mounting Configurations (NorComp Inc. 172 Series):

172-037-283L011 and 172-037-283L021 provide panel mount through-hole configurations with board-side (4-40) flanges. These parts maintain 5A current rating and extended operating temperature (-50°C ~ 125°C). Shell material differs (Nickel-plated steel versus Tin-plated steel) and contact material is Brass rather than Phosphor Bronze. ROHS3 compliance is provided. These substitutes are applicable where panel mounting is acceptable and the extended temperature range is beneficial.

172-037-283L001 features housing/shell unthreaded flange mounting, suitable for applications where panel mounting without threaded fasteners is required.

172-037-283L031 features mating-side (4-40) flange mounting, applicable where flange positioning on the mating connector side is required.

Compliance Considerations:

For new designs requiring RoHS compliance, FCE17C37SN480, 5745189-1, 5745189-7, 5747315-1, and NorComp 172 series variants are compliant. The original FCC17C37SN480 and TE Connectivity 745189-7 are non-compliant. TE Connectivity 747315-1 has not-applicable RoHS status.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SN480 directly replace FCC17C37SN480 in existing designs?

A: Yes. FCE17C37SN480 maintains identical mounting type (Through Hole), flange configuration (Board Side 4-40), position count (37), and operating temperature range (-40°C ~ 85°C). The primary difference is RoHS compliance status and dielectric material composition (Glass Filled Thermoplastic versus standard Thermoplastic). Electrical performance is equivalent.

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

A: Flange feature designates where the mounting fastener holes are located. Board-side (4-40) flanges mount to the PCB with fasteners on the connector body facing the board. Housing/shell unthreaded flanges mount without threaded fasteners. Mating-side (4-40) flanges position fastener holes on the side facing the mating connector. Selection depends on mechanical mounting requirements and available space.

Q: Are TE Connectivity AMPLIMITE parts suitable replacements despite lower voltage ratings?

A: TE Connectivity 5745189-1, 5745189-7, 5747315-1, 745189-7, and 747315-1 feature 125V voltage ratings versus the original 200V rating. These parts are suitable only if the application operates at or below 125V. Higher current ratings (6A versus 5A) and extended operating temperature ranges (-55°C ~ 105°C) provide additional margin in those parameters. Verify application voltage requirements before selection.

Q: What is the significance of contact material differences (Phosphor Bronze versus Brass)?

A: Both Phosphor Bronze and Brass are acceptable contact materials for D-Sub connectors. Phosphor Bronze (original FCC17C37SN480 and TE Connectivity parts) provides superior spring characteristics and wear resistance. Brass (NorComp 172 series) offers adequate performance for standard applications. Material selection does not affect electrical compatibility but may influence contact reliability in high-cycle mating applications.

Q: Do NorComp 172 series parts require different PCB footprints?

A: NorComp 172 series parts maintain the same 37-position D-Sub shell size (4, DC, C) and solder termination. Through-hole mounting is compatible with standard D-Sub PCB layouts. Panel mount variants (172-037-283L001, 172-037-283L011, 172-037-283L021, 172-037-283L031) accommodate both through-hole and panel-mount applications. Verify flange feature compatibility with mechanical mounting structure.

Q: Is inventory availability a factor in part selection?

A: Inventory levels are provided for reference. FCE17C37SN480 (1101 pcs), 5745189-7 (1761 pcs), and 745189-7 (2246 pcs) have highest availability. NorComp 172-037-283L031 has lowest availability (836 pcs). Inventory status may influence procurement timelines but does not affect technical suitability.

Q: What packaging formats are available?

A: FCC17C37SN480 and FCE17C37SN480 are supplied in standard packaging. NorComp 172 series parts are supplied in Trays. TE Connectivity AMPLIMITE parts (5745189-1, 5745189-7, 5747315-1, 745189-7, 747315-1) are supplied in Tubes. Packaging format does not affect connector performance but influences handling and storage procedures.

Q: Are all substitute parts rated for the same current and voltage as the original?

A: No. The original FCC17C37SN480 is rated 5A at 200V. FCE17C37SN480 maintains 5A rating with voltage rating not specified. NorComp 172 series maintains 5A with voltage rating not specified. TE Connectivity AMPLIMITE parts are rated 6A at 125V. Verify that application requirements do not exceed the selected part's ratings.
