Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCE17C37SB6EB is permissible with equivalent parts that maintain the following critical parameters:

Mandatory Matching Parameters:

• 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: Solder
• Contact Finish: Gold
• Shell Material, Finish: Steel, Tin Plated

Allowable Variation Parameters:

• Current Rating: Equal to or greater than 5A
• Operating Temperature Range: Equal to or greater than -40°C ~ 85°C
• Backset Spacing: Variation permitted within connector mechanical compatibility
• Flange Feature: Variation permitted (Board Side or Mating Side)
• Dielectric Material: Variation permitted (Thermoplastic or Polyamide based)
• Contact Finish Thickness: Variation permitted if gold plating is maintained

The substitute part 5745441-4 from TE Connectivity AMP Connectors meets all mandatory matching parameters and demonstrates acceptable variation in allowable parameters.

Engineering Selection Recommendations

Primary Part: FCE17C37SB6EB

The FCE17C37SB6EB remains the preferred selection when supply is available. This part is actively manufactured by Amphenol ICC, maintains RoHS compliance, carries UL94 V-0 flammability certification, and demonstrates full compliance with EAR99 export classification. Current inventory of 1103 pieces supports immediate procurement.

Equivalent Substitute: 5745441-4

The 5745441-4 from TE Connectivity AMP Connectors (AMPLIMITE HDP-20 series) is an acceptable equivalent substitute. This part satisfies all mandatory connector specifications including 37 position receptacle configuration, female socket contacts, right-angle through-hole mounting, and solder termination. The substitute demonstrates superior electrical performance with 6A current rating versus 5A, and extended operating temperature range of -55°C ~ 105°C versus -40°C ~ 85°C.

Both parts maintain identical shell size (4 DC, C), gold contact finish, steel tin-plated shell material, phosphor bronze contact material, and UL94 V-0 flammability rating. Both are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity classification.

Critical Consideration: The backset spacing differs between parts (0.405" versus 0.454") and flange mounting interfaces differ (Board Side M3 versus Mating Side Standard Screws). These mechanical variations require verification of PCB layout compatibility and mounting bracket specifications before substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can 5745441-4 be directly substituted for FCE17C37SB6EB without PCB modification?

A: Direct substitution requires verification of backset spacing compatibility and flange mounting interface. The FCE17C37SB6EB uses Board Side M3 mounting while 5745441-4 uses Mating Side Standard Screws. PCB layout and mounting bracket specifications must be reviewed to confirm mechanical compatibility.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching connector type (Receptacle, Female Sockets), position count (37), row configuration (2), shell size (4 DC, C), mounting style (Through Hole, Right Angle), termination method (Solder), and contact finish (Gold). Current rating and operating temperature may exceed the original specification.

Q: Are both parts RoHS compliant?

A: Yes. Both FCE17C37SB6EB and 5745441-4 are RoHS compliant and carry UL94 V-0 flammability certification. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the difference in current rating between these parts?

A: The FCE17C37SB6EB is rated for 5A maximum current, while the 5745441-4 is rated for 6A. The substitute part provides higher current capacity, which is acceptable for applications designed for the original 5A specification.

Q: Do both connectors support the same operating temperature range?

A: No. The FCE17C37SB6EB operates from -40°C to 85°C, while 5745441-4 operates from -55°C to 105°C. The substitute provides an extended temperature range suitable for wider environmental applications.

Q: What is the significance of the different backset spacing values?

A: Backset spacing (0.405" for FCE17C37SB6EB versus 0.454" for 5745441-4) affects the connector's depth when mounted on a PCB. This variation requires confirmation that the substitute connector physically fits within the available space and does not interfere with adjacent components or enclosure geometry.

Q: Are the dielectric materials functionally equivalent?

A: Both materials are glass-filled polymers meeting UL94 V-0 flammability requirements. The FCE17C37SB6EB uses Thermoplastic while 5745441-4 uses Polyamide (PA) Nylon. Both provide adequate electrical insulation and mechanical support for this connector class.

Q: What inventory status should influence part selection?

A: FCE17C37SB6EB maintains 1103 pieces in new original stock, while 5745441-4 maintains 950 pieces. Both parts demonstrate active production status and adequate availability for standard procurement timelines.
