Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The FCE17C37SC64B and 5745996-4 are functionally equivalent D-Sub 37-position receptacle connectors suitable for direct substitution in applications requiring through-hole solder termination with right-angle mounting. Both connectors maintain active product status and full RoHS compliance with UL94 V-0 flammability certification.

Substitution Basis:

The 5745996-4 (TE Connectivity AMPLIMITE HD-20 series) qualifies as a substitute based on matching core electrical and mechanical parameters: identical connector geometry (37-position, shell size 4), equivalent contact materials and finishes, identical termination method, and equivalent environmental ratings. The substitute part provides enhanced specifications in current capacity (6A versus 5A) and extended operating temperature range (-55°C to 105°C versus -40°C to 85°C), representing performance improvements without functional compromise.

Compliance Considerations:

Both connectors satisfy identical regulatory requirements: RoHS compliance, UL94 V-0 material flammability rating, EAR99 export classification, and HTSUS commodity code 8536.69.4040. Moisture sensitivity level 1 (unlimited) is maintained across both parts, indicating no special handling requirements during storage or assembly.

Inventory and Availability:

The FCE17C37SC64B maintains 690 pieces in new original stock. The substitute part 5745996-4 maintains 1030 pieces in new original stock, providing enhanced availability for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can the 5745996-4 be used as a direct replacement for the FCE17C37SC64B in existing designs?

A: Yes. The 5745996-4 maintains equivalent electrical and mechanical specifications across all critical parameters: 37-position receptacle configuration, shell size 4, through-hole right-angle solder termination, phosphor bronze contacts with gold finish, and steel tin-plated shell. Both connectors are RoHS compliant with UL94 V-0 certification and unlimited moisture sensitivity rating.

Q: What are the differences between these two connectors?

A: The primary differences are manufacturer (Amphenol ICC versus TE Connectivity), series designation (FCE17 versus AMPLIMITE HD-20), and flange feature design (board-side M3 versus housing/shell 4-40). The 5745996-4 provides higher current capacity (6A versus 5A), extended operating temperature range (-55°C to 105°C versus -40°C to 85°C), and thicker gold contact plating (30.0µin versus 15.0µin). These represent performance enhancements rather than functional differences.

Q: Are there any compatibility issues with PCB mounting?

A: No compatibility issues exist. Both connectors use identical through-hole right-angle mounting with 0.590" (14.99mm) backset spacing. The flange feature difference (board-side M3 versus housing/shell 4-40) does not affect PCB mounting compatibility, as both configurations are standard for D-Sub 37-position receptacles.

Q: Do these connectors require different soldering procedures?

A: No. Both connectors use identical solder termination methods and are compatible with standard PCB assembly processes. No procedural modifications are required when substituting between these parts.

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

A: The 5745996-4 features thicker gold plating (30.0µin versus 15.0µin), which provides enhanced corrosion resistance and extended contact life in demanding environments. This represents an improvement over the FCE17C37SC64B and does not create compatibility issues.

Q: Are both connectors suitable for the same voltage and current applications?

A: The 5745996-4 supports higher current capacity (6A versus 5A) and includes a specified voltage rating of 125V, whereas the FCE17C37SC64B does not specify voltage rating. For applications requiring 5A or less, both connectors are suitable. For applications approaching 5A, the 5745996-4 provides additional margin.

Q: What is the difference in operating temperature ranges?

A: The FCE17C37SC64B operates from -40°C to 85°C, while the 5745996-4 operates from -55°C to 105°C. The 5745996-4 provides extended temperature capability suitable for wider environmental conditions. For applications within the -40°C to 85°C range, both connectors are equivalent.

Q: Are there any regulatory or compliance differences?

A: No. Both connectors maintain identical compliance status: RoHS compliant, UL94 V-0 flammability rating, EAR99 export classification, and HTSUS code 8536.69.4040. Moisture sensitivity level 1 (unlimited) is equivalent across both parts.

Q: Which connector should be selected for new designs?

A: Selection depends on application requirements. For applications requiring standard specifications within -40°C to 85°C operating range and 5A current capacity, either connector is suitable. For applications requiring extended temperature range, higher current capacity, or enhanced contact durability, the 5745996-4 provides superior specifications.

Q: Is inventory availability a consideration in part selection?

A: The 5745996-4 maintains higher inventory (1030 pieces versus 690 pieces), which may provide advantages for procurement planning and lead time management. Both parts are classified as new original stock.
