Substitute Part Grouping Explanation

Substitution of the FCE17E09SC45B is determined by strict adherence to the following critical parameters:

Primary Substitution Criteria:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 9
• Number of Rows: 2
• Shell Size, Connector Layout: 1 (DE, E)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Type: Signal
• Flange Feature: 4-40 mounting specification

Secondary Compatibility Parameters:

• Shell Material, Finish: Steel, Tin Plated (primary); Steel, Nickel Plated (acceptable alternative)
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• Backset Spacing: 0.590" (14.99mm) or 0.584" (14.84mm) within tolerance
• Operating Temperature Range: Must encompass or exceed -40°C ~ 85°C

Substitute parts are grouped into two categories: Parametric Equivalents (identical specifications) and Similar Parts (functionally compatible with minor specification variations). All listed substitutes maintain the core D-Sub 9-position receptacle architecture and solder termination required for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent:

FCE17E09SC44B is a direct parametric equivalent to FCE17E09SC45B. 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 without design modification.

TE Connectivity AMPLIMITE HD-20 Series (5745988-6, 5747836-6, 747836-6):

These three TE Connectivity parts are functionally compatible substitutes. All three maintain the 9-position D-Sub receptacle configuration with through-hole right-angle mounting and solder termination. Key differences include:

• Higher current rating (6A versus 5A)
• Extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C)
• Higher contact finish thickness (30.0µin versus 15.0µin)
• Voltage rating of 125V (not specified on main part)
• ROHS3 or Not applicable RoHS status

These parts are suitable for applications requiring enhanced thermal performance or higher current capacity. The 5747836-6 and 747836-6 include board lock and ground strap features not present on the main part.

Mercury United Electronics 626 Series (626-009-262-032, 626-009-662-032):

These Mercury parts are functionally compatible substitutes with the following considerations:

• Lower current rating (3A per contact versus 5A)
• Nickel-plated steel shell (versus tin-plated)
• Board edge mounting capability in addition to through-hole
• Backset spacing of 0.584" (14.84mm) versus 0.590" (14.99mm), within standard tolerance
• Extended lower operating temperature (-55°C versus -40°C)
• Shielded design with board lock and mounting brackets

These parts are suitable for applications where lower current requirements exist and shielding is beneficial. The board edge mounting option provides additional design flexibility.

Compliance and Status:

All substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level. RoHS compliance is confirmed across all parts (RoHS Compliant or ROHS3 Compliant), with the exception of 747836-6 (Not applicable). All parts are active in production status with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can FCE17E09SC44B be used as a direct replacement for FCE17E09SC45B?

A: Yes. FCE17E09SC44B is a parametric equivalent with identical electrical and mechanical specifications. The parts differ only in packaging format. Direct substitution is supported without design modification.

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

A: Both series maintain the 9-position D-Sub receptacle configuration and are mechanically compatible. 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 TE parts also include voltage rating specification (125V) and additional features such as board lock and ground strap.

Q: Are Mercury 626 series connectors compatible with the FCE17E09SC45B?

A: Mercury 626-009-262-032 and 626-009-662-032 are functionally compatible substitutes with design considerations. Both maintain the 9-position D-Sub receptacle configuration, through-hole right-angle mounting, and solder termination. However, the Mercury parts have a lower current rating (3A per contact versus 5A) and nickel-plated shell finish instead of tin-plated. Backset spacing is 0.584" (14.84mm) versus 0.590" (14.99mm), within standard tolerance. These parts are suitable for applications with lower current requirements.

Q: What is the significance of contact finish thickness differences?

A: Contact finish thickness affects durability and mating cycle life. The main part FCE17E09SC45B has 15.0µin (0.38µm) gold finish, while substitute parts from TE Connectivity and Mercury 626-009-662-032 have 30.0µin (0.76µm) finish. Thicker gold plating provides enhanced wear resistance and is suitable for applications with frequent mating cycles or harsh environmental conditions. Mercury 626-009-262-032 has flash gold finish, which is thinner and suitable for lower-cycle applications.

Q: Can I use a substitute part with higher current rating in a design specified for 5A?

A: Yes. Substitute parts with higher current ratings (6A from TE Connectivity series) are suitable for designs specified at 5A. Higher current rating provides design margin and does not create compatibility issues. The connector will operate within its rated specifications.

Q: What is the impact of operating temperature range differences?

A: The main part FCE17E09SC45B operates from -40°C to 85°C. TE Connectivity AMPLIMITE HD-20 series parts operate from -55°C to 105°C, providing extended thermal range. Mercury 626 series parts operate from -55°C to 85°C. If your application requires operation below -40°C or above 85°C, TE Connectivity parts are required. For standard industrial applications within -40°C to 85°C, all substitutes are suitable.

Q: Are there packaging differences that affect component handling?

A: Yes. Packaging formats differ across substitutes: FCE17E09SC45B (unspecified), FCE17E09SC44B (Box), 5745988-6 (Tray), 5747836-6 (Tube), 747836-6 (Tube), and Mercury 626 series (Bulk). Packaging affects storage, handling, and automated assembly compatibility. Verify packaging requirements with your procurement and assembly processes before substitution.

Q: What does RoHS compliance status mean for these connectors?

A: All substitute parts are RoHS compliant (RoHS Compliant or ROHS3 Compliant), indicating they meet restrictions on hazardous substances. This is required for most commercial and industrial applications. The 747836-6 part shows "Not applicable" RoHS status, which may indicate it is a legacy part number. Confirm RoHS requirements with your application specifications before selection.

Q: Can I mix different manufacturer connectors in the same assembly?

A: While all listed substitutes are mechanically and electrically compatible, mixing manufacturers in the same assembly is not recommended without design review. Maintain consistency within a single design to ensure uniform performance, warranty coverage, and supply chain management. If substitution is necessary due to supply constraints, document the change and verify compatibility with your system requirements.
