The substitute part 5745441-4 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20 series) meets all mandatory matching parameters and demonstrates allowable variations in current rating (6A vs. 5A), operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C), and flange feature configuration (mating side with standard screws vs. board side M3).

Parameter Comparison

Engineering Selection Recommendations

Primary Part: FCE17C37SB68B

The FCE17C37SB68B is the specified component for applications requiring the exact board-side M3 flange configuration and 0.405" (10.29mm) backset spacing. This part maintains Active product status with established supply availability (698 units in stock). Selection of this part is appropriate when the mechanical mounting interface and specific flange design are critical to the application.

Substitute Part: 5745441-4

The 5745441-4 (TE Connectivity AMPLIMITE HDP-20 series) is a functional equivalent for applications where the mating-side flange configuration and 0.454" (11.53mm) backset spacing are compatible with the design. This substitute provides enhanced current rating capability (6A vs. 5A) and extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C), making it suitable for applications requiring higher thermal or electrical performance margins.

Both parts maintain identical compliance certifications (RoHS Compliant, UL94 V-0, EAR99, HTSUS 8536.69.4040) and share the same core connector architecture (37-position D-Sub receptacle, female sockets, through-hole right-angle solder termination, steel tin-plated shell, gold-plated contacts, phosphor bronze contact material, MSL 1).

Selection between these parts depends on mechanical mounting requirements and thermal/electrical performance specifications of the target application. The substitute part is available with 950 units in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the 5745441-4 be used as a direct replacement for the FCE17C37SB68B?

A: The 5745441-4 is functionally equivalent for 37-position D-Sub receptacle applications with identical connector architecture, pin count, and electrical characteristics. However, the flange feature differs (mating side with standard screws vs. board side M3), and backset spacing varies (0.454" vs. 0.405"). Mechanical compatibility with the target PCB layout and mounting structure must be verified before substitution.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Flange configuration and mounting interface, (2) Backset spacing tolerance, (3) Current rating (6A vs. 5A), (4) Operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C), and (5) Dielectric material composition (polyamide vs. thermoplastic). All other electrical and mechanical parameters remain equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both the FCE17C37SB68B and 5745441-4 are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

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

A: Backset spacing (0.405" vs. 0.454") defines the distance from the connector mounting surface to the rear of the connector body. This parameter affects PCB layout, component clearance, and mechanical fit within the enclosure. Designs must accommodate the specific backset spacing of the selected part.

Q: Can the 5745441-4 handle higher current than the FCE17C37SB68B?

A: Yes, the 5745441-4 is rated for 6A compared to the FCE17C37SB68B at 5A. Applications requiring current levels between 5A and 6A may benefit from the substitute part's higher current rating.

Q: What is the operating temperature difference, and when does it matter?

A: The FCE17C37SB68B operates from -40°C to 85°C, while the 5745441-4 operates from -55°C to 105°C. The substitute part provides extended low-temperature and high-temperature capability. Applications in extreme thermal environments or with stringent temperature margin requirements should consider the 5745441-4.

Q: Are the contact materials the same?

A: Yes, both parts use phosphor bronze contact material with gold plating. The contact finish provides equivalent electrical performance and corrosion resistance.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the connector has no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures, simplifying inventory management and logistics.

Q: How do the flange features affect installation?

A: The FCE17C37SB68B uses a board-side M3 flange for direct PCB mounting with M3 fasteners. The 5745441-4 uses a mating-side flange with standard screws, which may require different mounting hardware and installation procedures. The choice depends on the mechanical design of the target application.

Q: Are both parts suitable for solder termination?

A: Yes, both parts are designed for solder termination to PCB pads. The through-hole right-angle configuration supports standard wave soldering and hand soldering processes.
