Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCC17C37SE490 is determined by strict equivalence across the following critical parameters: connector type (receptacle, female sockets), number of positions (37), number of rows (2), shell size and layout (4 DC, C), mounting type (through hole), and termination method (solder). All substitute parts listed maintain these core specifications, ensuring mechanical and electrical compatibility with mating connectors and PCB layouts designed for the original part.

The substitute parts are grouped based on manufacturer and product status. The FCE17C37SE490 represents an active-status equivalent from the same manufacturer with identical core specifications. The Mercury United Electronics parts (628-037-220-046 and 628-037-220-047) provide metal-shell alternatives with maintained electrical and mechanical compatibility. The TE Connectivity part (7-1393740-3) offers an alternative from a major connector supplier within the same D-Sub category.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete FCC17C37SE490, the FCE17C37SE490 from Amphenol ICC is the primary equivalent. This part maintains identical core specifications and is currently in active production status, ensuring long-term availability and supply chain stability. The FCE17C37SE490 is RoHS compliant, meeting modern environmental and regulatory requirements.

The Mercury United Electronics parts (628-037-220-046 and 628-037-220-047) provide functionally equivalent alternatives with metal-shell construction. The 628-037-220-047 offers extended operating temperature range (-55°C to 85°C) and ROHS3 compliance, making it suitable for applications with broader temperature requirements or stricter regulatory mandates.

The TE Connectivity part (7-1393740-3) from the AMPLIMITE HD-20 series represents an alternative from a major connector manufacturer. This part is RoHS compliant and maintains the required 37-position, 2-row D-Sub configuration with solder termination.

Selection should prioritize active-status parts (FCE17C37SE490, 628-037-220-047, 7-1393740-3) over the obsolete original to ensure continued availability and support. RoHS compliance status should be verified against specific application requirements and regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SE490 be used as a direct replacement for the FCC17C37SE490?

A: Yes. Both parts share identical core specifications: 37 positions, 2 rows, shell size 4 (DC, C), through-hole mounting, and solder termination. The FCE17C37SE490 is the active-production equivalent and is recommended for new designs and ongoing maintenance.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: The FCC17C37SE490 and FCE17C37SE490 feature tin-plated steel shells, while the Mercury United Electronics parts (628-037-220-046 and 628-037-220-047) feature nickel-plated steel shells. Both finishes provide corrosion resistance and are suitable for standard industrial environments. Selection depends on specific environmental exposure and application requirements.

Q: Are all substitute parts mechanically compatible with the original connector?

A: Yes. All substitute parts maintain the same shell size (4 DC, C), mounting configuration (through hole), and contact arrangement (37 positions, 2 rows), ensuring mechanical compatibility with mating connectors and PCB layouts designed for the FCC17C37SE490.

Q: What is the significance of the extended operating temperature range in the 628-037-220-047?

A: The 628-037-220-047 operates from -55°C to 85°C, compared to -40°C to 85°C for the original part. This extended lower temperature limit makes it suitable for applications in extreme cold environments or aerospace applications where broader temperature performance is required.

Q: How does RoHS compliance affect part selection?

A: The original FCC17C37SE490 is RoHS non-compliant. All substitute parts listed are RoHS compliant or ROHS3 compliant, meeting current environmental regulations. For applications subject to RoHS requirements, selection must be limited to compliant alternatives: FCE17C37SE490, 628-037-220-047, or 7-1393740-3.

Q: What current rating should be used when selecting a substitute?

A: The original part is rated at 5A. The 628-037-220-047 is rated at 3A per contact. For applications requiring the full 5A rating, verify that the selected substitute meets this specification or confirm that the application current requirements are compatible with the substitute part's rating.
