Engineering Selection Recommendations
Primary Recommendation: FCE17B25SN2D0
The FCE17B25SN2D0 from Amphenol ICC (Commercial Products) is the closest functional equivalent to the obsolete FCC17B25SN2D0. This part maintains identical connector geometry, position count, mounting configuration, and operating temperature range. The FCE17B25SN2D0 is active in production status and RoHS Compliant, addressing regulatory requirements for new designs. The dielectric material is upgraded to Thermoplastic, Glass Filled composition. This substitute requires no PCB layout modifications and provides direct pin-for-pin compatibility.
Secondary Recommendations: NorComp 172-025 Series
The NorComp 172-025-283L001, 172-025-283L011, 172-025-283L021, and 172-025-283L031 connectors provide functional equivalence with extended operating temperature range (-50°C to 125°C) and ROHS3 Compliance. These parts feature panel mount capability in addition to through-hole mounting, offering design flexibility. Contact material is brass rather than phosphor bronze. Shell finish is nickel-plated steel. Flange configurations vary across the series (Housing/Shell Unthreaded, Board Side 4-40, or Mating Side 4-40), requiring verification of mechanical fit within the target application.
Tertiary Recommendations: TE Connectivity AMPLIMITE HDP-20 Series
The 205738-3, 205738-7, 5205738-1, and 5205738-3 connectors from TE Connectivity provide functional equivalence with elevated current rating (6A) and extended operating temperature range (-55°C to 105°C). The 5205738-3 variant is RoHS Compliant, while 205738-3 and 205738-7 are RoHS non-compliant. Voltage rating is specified at 125V, which is lower than the original 200V specification. Shell finish is yellow chromate-plated zinc. These parts are suitable for applications where higher current capacity and extended temperature operation are beneficial.
Compliance Considerations:
For new designs requiring RoHS Compliance, FCE17B25SN2D0, NorComp 172-025 series (ROHS3), or 5205738-3 (RoHS Compliant) are appropriate selections. For legacy system maintenance or applications without RoHS requirements, all listed substitutes remain functionally compatible. Voltage rating derating should be evaluated when selecting TE Connectivity parts rated at 125V for applications originally specified at 200V.
Frequently Asked Questions (FAQ)
Q: Can the FCE17B25SN2D0 be used as a direct replacement for FCC17B25SN2D0 without PCB modifications?
A: Yes. The FCE17B25SN2D0 maintains identical connector geometry, pin count, row configuration, shell size, and through-hole mounting type. No PCB layout changes are required. The part is pin-for-pin compatible and operates within the same temperature range.
Q: What is the primary difference between Amphenol ICC FCC17 and FCE17 series connectors?
A: The FCE17B25SN2D0 is the active production equivalent of the obsolete FCC17B25SN2D0. The FCE17 series features upgraded dielectric material (Thermoplastic, Glass Filled) and RoHS Compliance status. Electrical and mechanical specifications remain functionally equivalent.
Q: Are NorComp 172-025 connectors suitable for through-hole mounting applications?
A: Yes. The NorComp 172-025 series supports both panel mount and through-hole mounting configurations. Specific flange designs (Housing/Shell Unthreaded, Board Side 4-40, or Mating Side 4-40) determine the mounting method. Verify flange type compatibility with your application before selection.
Q: What is the significance of the voltage rating difference between FCC17B25SN2D0 (200V) and TE Connectivity 205738-3 (125V)?
A: The original FCC17B25SN2D0 is rated for 200V operation. TE Connectivity AMPLIMITE HDP-20 series parts are rated at 125V. For applications requiring 200V operation, select FCE17B25SN2D0 or NorComp 172-025 series connectors, which do not specify voltage limitations below the original specification. Voltage derating analysis is required if TE Connectivity parts are selected for 200V applications.
Q: Which substitute part offers the widest operating temperature range?
A: NorComp 172-025 series and TE Connectivity AMPLIMITE HDP-20 series connectors both provide extended operating temperature ranges (-50°C to 125°C and -55°C to 105°C respectively) compared to the original FCC17B25SN2D0 specification (-40°C to 85°C). Selection depends on specific application temperature requirements.
Q: Are all substitute parts RoHS Compliant?
A: No. FCE17B25SN2D0, NorComp 172-025 series (ROHS3 Compliant), and 5205738-3 (RoHS Compliant) meet RoHS requirements. The 205738-3 and 205738-7 TE Connectivity parts are RoHS non-compliant. Regulatory requirements for your application determine appropriate part selection.
Q: What is the difference between contact materials (Phosphor Bronze vs. Brass) in substitute connectors?
A: Both phosphor bronze and brass are acceptable contact materials for D-Sub receptacle connectors. Phosphor bronze is used in FCC17B25SN2D0, FCE17B25SN2D0, and TE Connectivity parts. Brass is used in NorComp 172-025 series. Both materials provide equivalent electrical performance and contact reliability for signal-level applications at the specified current ratings.
Q: Can FCC17B25SN2D0 be replaced with a higher current-rated connector such as 205738-3 (6A)?
A: Yes. The 205738-3 connector is rated for 6A, exceeding the original 5A specification. Higher current ratings provide design margin and are functionally compatible. However, voltage rating (125V vs. 200V) must be evaluated for your specific application requirements.
Q: What packaging options are available for substitute connectors?
A: Packaging varies by manufacturer and part number. FCE17B25SN2D0 is supplied in standard packaging. NorComp 172-025 series is supplied in Tray packaging. TE Connectivity 205738-3 and 205738-7 are supplied in Bulk packaging, while 5205738-3 is supplied in Tube packaging. Verify packaging compatibility with your procurement and assembly processes.
Q: Are there any mechanical differences between Housing/Shell (Unthreaded) and Panel Mount flange designs?
A: Yes. Housing/Shell (Unthreaded) flanges are designed for vertical through-hole mounting on PCBs without mechanical fastening. Panel Mount flanges with 4-40 threaded holes (Board Side or Mating Side) provide mechanical retention to panel structures. Application mounting method determines appropriate flange selection.
