Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SB2EB is determined by strict alignment of core electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Critical Matching Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 37
• Number of rows: 2
• Shell size, connector layout: 4 (DC, C)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold
• Material flammability rating: UL94 V-0
• RoHS compliance: RoHS Compliant

Allowable Parameter Variations: Substitute parts may differ in current rating, operating temperature range, backset spacing, flange feature design, dielectric material composition, and voltage rating, provided the core electrical and mechanical specifications remain compatible with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5745441-4 is a qualified substitute for the Amphenol ICC FCE17C37SB2EB based on matching core electrical and mechanical specifications. Both connectors are actively produced, RoHS compliant, and carry identical ECCN and HTSUS classifications.

Compatibility Assessment:

The 5745441-4 maintains all critical parameters required for direct substitution: D-Sub receptacle configuration, 37-position female socket arrangement, 2-row layout, shell size 4 (DC, C), through-hole right-angle mounting, and solder termination. Both connectors feature steel tin-plated shells with gold-plated contacts and UL94 V-0 flammability ratings.

Performance Considerations:

The TE Connectivity substitute provides enhanced current capacity (6A versus 5A) and an extended operating temperature range (-55°C to 105°C versus -40°C to 85°C). The backset spacing differs by 0.049 inches (1.24mm), which may affect mechanical fit in space-constrained applications. The dielectric material composition differs (polyamide nylon glass-filled versus thermoplastic glass-filled), though both materials meet the same flammability standard.

Compliance Status:

Both parts maintain RoHS compliance and unlimited moisture sensitivity level (MSL 1) ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5745441-4 be used as a direct replacement for the Amphenol ICC FCE17C37SB2EB?

A: Yes. Both connectors share identical connector style, type, position count, row configuration, shell size, mounting method, and termination approach. The core electrical and mechanical specifications align, supporting direct substitution in applications designed for the FCE17C37SB2EB.

Q: What is the significance of the backset spacing difference between these connectors?

A: Backset spacing (0.405 inches for FCE17C37SB2EB versus 0.454 inches for 5745441-4) defines the distance from the mounting flange to the mating face. This 0.049-inch difference may impact mechanical fit in applications with tight spatial constraints or specific PCB layout requirements. Verify mounting clearance in your application before substitution.

Q: Are there differences in current-carrying capacity between these parts?

A: The FCE17C37SB2EB is rated for 5A, while the 5745441-4 is rated for 6A. The substitute part provides higher current capacity, making it suitable for applications requiring the original 5A rating. Applications designed for higher current loads may benefit from the increased capacity of the substitute.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability ratings, maintain MSL 1 (unlimited) moisture sensitivity levels, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the difference in operating temperature ranges?

A: The FCE17C37SB2EB operates from -40°C to 85°C, while the 5745441-4 operates from -55°C to 105°C. The substitute provides a wider temperature envelope, supporting applications in more extreme thermal environments. For applications within the original temperature range, both connectors are functionally equivalent.

Q: How do the dielectric materials differ between these connectors?

A: The FCE17C37SB2EB uses thermoplastic glass-filled dielectric material, while the 5745441-4 uses polyamide (PA) nylon glass-filled material. Both materials achieve UL94 V-0 flammability ratings and provide equivalent electrical insulation properties for this connector category.

Q: Are there any packaging or inventory considerations for these parts?

A: The FCE17C37SB2EB is available in 1,040 units in stock, while the 5745441-4 is available in 950 units in stock. Both are actively produced and maintained in inventory, supporting consistent supply availability.
