Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent (Direct Substitution):

FCE17E09SC44B is a parametric equivalent to FCE17E09SC40B. Both parts are manufactured by Amphenol ICC within the FCE17 series and share identical electrical and mechanical specifications. The only difference is packaging format (Box versus unspecified). This part is suitable for direct substitution with no design modifications required. Current inventory of 1209 units exceeds the main part availability.

Compatible Alternatives (TE Connectivity AMPLIMITE HD-20 Series):

Parts 5745988-6, 5747836-6, and 747836-6 are manufactured by TE Connectivity within the AMPLIMITE HD-20 series. These connectors meet all primary equivalence criteria and provide enhanced specifications:

• Current rating increased to 6A (exceeds 5A requirement)
• Operating temperature range extended to -55°C ~ 105°C (exceeds -40°C ~ 85°C requirement)
• Contact finish thickness increased to 30.0µin (exceeds 15.0µin requirement)
• Voltage rating specified at 125V (not specified in main part)
• ROHS3 Compliant status (meets or exceeds RoHS Compliant requirement)

These parts are suitable for applications where enhanced thermal performance or higher current capacity is beneficial. Flange feature differences (Mating Side, Female Screwlock versus Board Side) require verification of mounting interface compatibility.

Compatible Alternatives (Mercury United Electronics 626 Series):

Parts 626-009-262-032 and 626-009-662-032 are manufactured by Mercury United Electronics within the 626 series. These connectors meet primary equivalence criteria with the following considerations:

• Current rating specified as 3A per contact (lower than 5A main part specification)
• Backset spacing of 0.584" (within mechanical tolerance of 0.590")
• Mounting type includes Board Edge option (additional capability)
• Shell finish is Nickel Plated (alternative to Tin Plated)
• ROHS3 Compliant status
• REACH Unaffected designation

These parts are suitable for applications where current requirements do not exceed 3A per contact and where board edge mounting capability is advantageous. The lower current rating restricts use in higher-power applications.

Compliance and Regulatory Status:

All substitute parts maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level, ensuring compliance with standard industrial requirements. RoHS and ROHS3 compliance is maintained across all alternatives. REACH status varies by manufacturer but does not preclude substitution in non-REACH-restricted applications.

Frequently Asked Questions (FAQ)

Q: Can FCE17E09SC44B be used as a direct replacement for FCE17E09SC40B?

A: Yes. FCE17E09SC44B is a parametric equivalent manufactured by the same company (Amphenol ICC) within the same series (FCE17). All electrical and mechanical specifications are identical. The only difference is packaging format. No design modifications are required.

Q: What are the key differences between Amphenol ICC FCE17 series and TE Connectivity AMPLIMITE HD-20 series connectors?

A: Both series meet the core 9-position D-Sub receptacle requirements. The AMPLIMITE HD-20 series (5745988-6, 5747836-6, 747836-6) provides higher current rating (6A versus 5A), extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C), and thicker gold contact finish (30.0µin versus 15.0µin). The flange feature differs: AMPLIMITE HD-20 uses Mating Side Female Screwlock while FCE17 uses Board Side. Verify mounting interface compatibility before substitution.

Q: Are Mercury United Electronics 626 series connectors suitable for all applications using FCE17E09SC40B?

A: Mercury United 626 series connectors (626-009-262-032, 626-009-662-032) are suitable only for applications where current requirements do not exceed 3A per contact. The main part FCE17E09SC40B is rated for 5A, making Mercury United parts unsuitable for higher-current applications. Verify application current requirements before selecting these alternatives.

Q: What is the significance of backset spacing differences (0.590" versus 0.584")?

A: Backset spacing of 0.590" (14.99mm) is the standard for DE/E shell size D-Sub connectors. Mercury United 626 series parts specify 0.584" (14.84mm), which is within mechanical tolerance but represents a minor dimensional variation. This difference is typically accommodated by standard PCB footprints but should be verified against specific board design requirements.

Q: Do all substitute parts have the same flange feature?

A: No. FCE17E09SC40B and FCE17E09SC44B feature Board Side flange (4-40). TE Connectivity AMPLIMITE HD-20 series parts feature Mating Side Female Screwlock (4-40). Mercury United 626 series parts feature Housing/Shell flange (4-40). Flange feature determines mounting interface compatibility. Verify that the selected substitute matches the mounting interface of the original design.

Q: What is the difference between Tin Plated and Nickel Plated shell finishes?

A: FCE17E09SC40B and most TE Connectivity alternatives use Steel Tin Plated shells. Mercury United 626 series uses Steel Nickel Plated shells. Both finishes provide corrosion resistance and are suitable for standard industrial environments. Nickel plating provides enhanced durability in harsh environments but may introduce compatibility considerations in sensitive applications. Verify material compatibility with application environment.

Q: Are there any RoHS compliance differences between substitute parts?

A: FCE17E09SC40B is RoHS Compliant. TE Connectivity parts are ROHS3 Compliant (enhanced standard). Mercury United parts are ROHS3 Compliant. ROHS3 represents a more stringent compliance level than RoHS Compliant. All parts meet or exceed RoHS requirements and are suitable for RoHS-restricted applications.

Q: What packaging formats are available for these connectors?

A: FCE17E09SC40B packaging is not specified. FCE17E09SC44B is supplied in Box format. TE Connectivity 5745988-6 is supplied in Tray format. TE Connectivity 5747836-6 and 747836-6 are supplied in Tube format. Mercury United 626-009-262-032 and 626-009-662-032 are supplied in Bulk format. Packaging selection depends on procurement volume and handling requirements.

Q: Can I substitute a part with higher current rating (6A) in an application designed for 5A?

A: Yes. Substituting a connector with higher current rating (6A) in an application designed for 5A is acceptable. The higher rating provides additional safety margin and does not negatively impact performance. However, the application circuit must still be designed for the original 5A specification.

Q: What is the operating temperature range difference between parts?

A: FCE17E09SC40B operates from -40°C to 85°C. TE Connectivity AMPLIMITE HD-20 series operates from -55°C to 105°C (extended range). Mercury United 626 series operates from -55°C to 85°C (lower temperature extended, upper temperature same). Select parts based on application temperature requirements. Extended range parts are suitable for wider temperature applications.
