Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5745781-7 are identified based on electrical and mechanical parameter equivalence within the D-Sub receptacle connector category. All substitute parts maintain identical specifications across the following critical parameters: connector style (D-Sub), connector type (receptacle with female sockets), position count (9), row configuration (2), shell size and layout (1 DE, E), mounting type (through-hole right angle), termination method (solder), current rating (6A), voltage rating (125V), operating temperature range (-55°C to 105°C), shell material and finish (steel, tin plated), contact finish (gold), contact material (phosphor bronze), flange feature (housing/shell 4-40), ground strap feature, UL94 V-0 flammability rating, thermoplastic dielectric, backset spacing (0.318" / 8.08mm), and MSL rating (1).

Substitution is permitted when all electrical and mechanical parameters align with the main part specification. Variations in RoHS compliance status and REACH classification do not affect functional interchangeability but must be evaluated within the context of end-application regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5745781-7, 5745781-4, and 745781-4—are functionally equivalent D-Sub receptacle connectors with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory compliance requirements and product status considerations.

5745781-7 (Main Part): RoHS Compliant with Vendor Undefined REACH status. Suitable for applications requiring RoHS compliance. Active product status ensures ongoing availability and support.

5745781-4 (Substitute): ROHS3 Compliant with REACH Unaffected status. Provides enhanced regulatory clarity with explicit REACH classification. Active product status. This part offers the most comprehensive compliance documentation for applications with strict regulatory requirements.

745781-4 (Substitute): RoHS non-compliant with REACH Unaffected status. Suitable for applications where RoHS compliance is not required. Active product status. This part provides the highest inventory availability (2473 pieces) among the three options.

All parts carry identical electrical ratings, mechanical dimensions, material specifications, and operational characteristics. Selection should be based on end-application regulatory requirements and inventory availability constraints.

Frequently Asked Questions (FAQ)

Q: Are the 5745781-7, 5745781-4, and 745781-4 connectors mechanically interchangeable?

A: Yes. All three connectors share identical mechanical specifications including shell size (1 DE, E), mounting type (through-hole right angle), backset spacing (0.318" / 8.08mm), and flange configuration (housing/shell 4-40). They are directly interchangeable in PCB layouts and mechanical assemblies.

Q: Are these connectors electrically interchangeable?

A: Yes. All three connectors have identical electrical specifications: 9-position configuration, 6A current rating, 125V voltage rating, gold-plated phosphor bronze contacts, and operating temperature range of -55°C to 105°C. They perform identically in electrical applications.

Q: What is the difference between RoHS Compliant, ROHS3 Compliant, and RoHS non-compliant?

A: RoHS Compliant indicates conformance to the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates conformance to the updated RoHS 3 directive with expanded scope. RoHS non-compliant indicates the part does not meet RoHS requirements. Selection depends on end-application regulatory jurisdiction and customer requirements.

Q: What does REACH Unaffected mean compared to Vendor Undefined?

A: REACH Unaffected indicates the part is explicitly classified as not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) requirements. Vendor Undefined indicates the REACH status has not been formally classified by the manufacturer. REACH Unaffected provides clearer regulatory documentation.

Q: Can I substitute 745781-4 for 5745781-7 in a RoHS-compliant application?

A: No. The 745781-4 is RoHS non-compliant and cannot be used in applications requiring RoHS compliance. Use either 5745781-7 (RoHS Compliant) or 5745781-4 (ROHS3 Compliant) for RoHS-regulated applications.

Q: Which part has the best inventory availability?

A: The 745781-4 has the highest inventory availability with 2473 pieces in stock, compared to 1616 pieces for 5745781-4 and 683 pieces for 5745781-7.

Q: Are there any differences in contact finish or material between these parts?

A: No. All three connectors have identical contact specifications: gold finish at 30.0µin (0.76µm) thickness, phosphor bronze contact material, and ground strap feature.

Q: What is the significance of the AMPLIMITE HD-20 series designation?

A: AMPLIMITE HD-20 is the product series classification for all three connectors, indicating they belong to the same connector family with consistent design standards and performance characteristics.

Q: Can these connectors be used in high-temperature applications?

A: Yes. All three connectors are rated for operating temperatures from -55°C to 105°C, making them suitable for industrial and commercial high-temperature applications within this range.

Q: What is the flange feature (Housing/Shell 4-40) used for?

A: The 4-40 flange feature refers to the mounting holes in the connector housing that accept 4-40 screws for mechanical attachment to the PCB or chassis, providing secure mechanical retention.
