Engineering Selection Recommendations
Primary Substitute: FCE17C37SN2D0
The FCE17C37SN2D0 from Amphenol ICC represents the direct active equivalent to the obsolete FCC17C37SN2D0. This part maintains identical connector geometry, electrical ratings, and mounting configuration while offering active product status and RoHS compliance. The FCE17 series is the current production line replacement for the FCC17 series. Selection of FCE17C37SN2D0 eliminates design modification requirements and ensures long-term supply continuity.
Secondary Substitutes: TE Connectivity AMPLIMITE Series (745189-7, 747315-1, 5745189-7, 5747315-1)
The TE Connectivity AMPLIMITE HD-20 and HDP-20 series connectors provide functional equivalence with enhanced electrical performance (6A current rating versus 5A). These parts maintain identical 37-position, 2-row D-Sub configuration with solder termination and through-hole mounting. Selection of TE Connectivity parts is appropriate when higher current capacity or extended operating temperature range (-55°C to 105°C) is required. The 5745189-7 and 5747315-1 variants offer RoHS3 compliance for regulated applications.
Tertiary Substitutes: NorComp 172-037 Series (172-037-283L001, 172-037-283L011, 172-037-283L021, 172-037-283L031)
The NorComp 172-037 series provides panel-mount D-Sub receptacles with identical 37-position configuration and solder termination. These connectors feature extended operating temperature range (-50°C to 125°C) and ROHS3 compliance. Selection of NorComp parts is appropriate for applications requiring panel-mount installation with board-side or mating-side flange configurations. The 172-037-283L001 variant with unthreaded housing provides closest form-fit compatibility to the original FCC17C37SN2D0.
Compliance Considerations:
For new designs or applications subject to RoHS regulations, FCE17C37SN2D0, 5745189-7, 5747315-1, or NorComp 172-037 series parts are required. The original FCC17C37SN2D0 and TE Connectivity 745189-7 are non-compliant and suitable only for legacy system maintenance or non-regulated applications.
Frequently Asked Questions (FAQ)
Q: Can FCE17C37SN2D0 be used as a direct replacement for FCC17C37SN2D0 without PCB modification?
A: Yes. The FCE17C37SN2D0 maintains identical connector geometry, pin configuration, mounting footprint, and electrical interface. No PCB layout changes are required. The FCE17 series is the active production equivalent of the obsolete FCC17 series.
Q: What is the difference between the TE Connectivity 745189-7 and 5745189-7 variants?
A: Both parts are AMPLIMITE series 37-position D-Sub receptacles with identical electrical and mechanical specifications. The primary difference is RoHS compliance status: 745189-7 is RoHS non-compliant, while 5745189-7 is RoHS3 compliant. For regulated applications, 5745189-7 is required.
Q: Are NorComp 172-037 series connectors compatible with the original FCC17C37SN2D0 mounting?
A: NorComp 172-037 series connectors are panel-mount variants with flange features (board-side or mating-side mounting holes). The original FCC17C37SN2D0 features unthreaded housing without mounting holes. The 172-037-283L001 variant with unthreaded housing provides closest compatibility but is classified as panel-mount through-hole. PCB layout evaluation is required to confirm mounting compatibility.
Q: What is the significance of the flange feature designation (unthreaded, board-side, mating-side)?
A: The flange feature determines the mounting method and orientation. Unthreaded housing (FCC17C37SN2D0, FCE17C37SN2D0, 745189-7, 5745189-7) mounts vertically through the PCB without fastening holes. Board-side flange (747315-1, 5747315-1, 172-037-283L011, 172-037-283L021) includes 4-40 mounting holes on the board-facing side. Mating-side flange (172-037-283L031) includes 4-40 mounting holes on the connector-facing side. Selection depends on mechanical mounting requirements.
Q: Can TE Connectivity 6A-rated connectors be used in applications designed for 5A current?
A: Yes. The 6A current rating of TE Connectivity AMPLIMITE series (745189-7, 747315-1, 5745189-7, 5747315-1) exceeds the 5A requirement of the original FCC17C37SN2D0. These parts are backward-compatible for 5A applications and provide additional current capacity margin.
Q: What is the impact of voltage rating differences (200V original versus 125V TE Connectivity)?
A: The original FCC17C37SN2D0 specifies 200V voltage rating. TE Connectivity AMPLIMITE series parts specify 125V. For applications operating at voltages between 125V and 200V, the original FCC17C37SN2D0 or FCE17C37SN2D0 must be selected. For applications operating below 125V, TE Connectivity parts are suitable.
Q: Are there packaging differences between substitute parts?
A: Yes. FCC17C37SN2D0 and FCE17C37SN2D0 are supplied in standard packaging. TE Connectivity AMPLIMITE series parts are supplied in tube packaging. NorComp 172-037 series parts are supplied in tray packaging. Packaging differences do not affect connector functionality but may impact procurement and handling procedures.
Q: Which substitute part offers the widest operating temperature range?
A: NorComp 172-037 series connectors specify -50°C to 125°C operating temperature range, which is wider than the original FCC17C37SN2D0 (-40°C to 85°C) and TE Connectivity AMPLIMITE series (-55°C to 105°C). Selection of NorComp parts is appropriate for applications requiring extended temperature operation.
Q: Is contact material (phosphor bronze versus brass) a critical substitution factor?
A: Contact material affects electrical conductivity and mechanical durability. The original FCC17C37SN2D0 uses phosphor bronze contacts. NorComp 172-037 series uses brass contacts. Both materials are acceptable for signal-level D-Sub applications. TE Connectivity AMPLIMITE series uses phosphor bronze, matching the original specification. Contact material selection should be evaluated based on application-specific requirements for contact resistance and wear characteristics.
