Parameter Comparison

Engineering Selection Recommendations

Primary Part: FCE17C37SC29B

The FCE17C37SC29B is the specified component and should be used when available. This part is active in production with 850 units in current inventory. It carries full RoHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

Substitute Part: 5745996-4

The 5745996-4 from TE Connectivity AMP Connectors is a direct functional equivalent. Both parts share identical mechanical and electrical specifications for all critical parameters including connector style, position count, shell size, mounting configuration, and termination method. The substitute part offers the following characteristics:

• Active production status with 1030 units in inventory
• RoHS compliant
• UL94 V-0 flammability rating
• Enhanced contact finish thickness (30.0µin vs. 15.0µin)
• Higher current rating (6A vs. 5A)
• Extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C)
• Threaded flange feature (4-40) vs. unthreaded housing
• Ground strap feature included

Selection between the primary and substitute part should be based on application requirements, inventory availability, and procurement lead times. Both parts are suitable for equivalent circuit board integration and mating connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC29B?

A: Yes. Both connectors share identical specifications for connector style, position count (37), row configuration (2), shell size (4 DC, C), mounting type (through-hole right-angle), termination method (solder), shell material and finish (steel, tin plated), contact finish (gold), and backset spacing (0.590"). The parts are mechanically and electrically interchangeable for PCB mounting and mating connector applications.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Contact finish thickness is thicker on the 5745996-4 (30.0µin vs. 15.0µin); (2) Current rating is higher on the 5745996-4 (6A vs. 5A); (3) Operating temperature range is wider on the 5745996-4 (-55°C ~ 105°C vs. -40°C ~ 85°C); (4) The 5745996-4 includes a threaded flange (4-40) while the FCE17C37SC29B has an unthreaded housing; (5) The 5745996-4 includes a ground strap feature; (6) The 5745996-4 has a specified voltage rating of 125V.

Q: Are both parts RoHS compliant?

A: Yes. Both the FCE17C37SC29B and 5745996-4 are RoHS compliant and carry UL94 V-0 flammability certification.

Q: What is the significance of the different flange features?

A: The FCE17C37SC29B features an unthreaded housing/shell flange, while the 5745996-4 features a threaded 4-40 flange. This difference affects mounting method. The threaded flange on the 5745996-4 allows for screw-based mechanical retention, whereas the unthreaded housing on the FCE17C37SC29B relies on other mounting mechanisms such as brackets or clips.

Q: Can I use the 5745996-4 if my application requires the unthreaded housing design?

A: The presence of a threaded flange on the 5745996-4 does not prevent its use in applications designed for unthreaded housings. The threaded feature is an additional capability. However, if the PCB layout or mechanical assembly specifically requires the absence of threaded holes, the FCE17C37SC29B should be used.

Q: What does the ground strap feature on the 5745996-4 provide?

A: The ground strap is an additional feature that provides enhanced grounding capability. This feature does not prevent the 5745996-4 from being used in applications that do not require it.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the inventory status for each part?

A: The FCE17C37SC29B has 850 units in stock. The 5745996-4 has 1030 units in stock. Both parts are available for immediate procurement.
