Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 745076-4 are classified based on electrical and mechanical parameter equivalence within the AMPLIMITE HD-20 D-Sub connector family. Substitution eligibility is determined by matching the following critical parameters:

Electrical Parameters:

• Voltage Rating: 125V
• Current Rating: 6A
• Contact Material: Phosphor Bronze
• Contact Type: Signal

Mechanical Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 9
• Number of Rows: 2
• Shell Size, Connector Layout: 1 (DE, E)
• Mounting Type: Through Hole
• Termination: Solder
• Flange Feature: Mating Side, Female Screwlock (4-40)

Environmental Parameters:

• Operating Temperature Range: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as direct substitutes. Variations in contact finish thickness or RoHS compliance status do not affect functional interchangeability when all primary electrical and mechanical parameters remain constant.

Engineering Selection Recommendations

5745076-4 (Direct Substitute - Recommended for New Designs)

The 5745076-4 is the primary substitute for the 745076-4. This part maintains complete electrical and mechanical equivalence across all critical parameters. The 5745076-4 carries ROHS3 compliance status, making it suitable for applications subject to RoHS regulatory requirements. Inventory availability is higher at 2283 pieces, supporting production continuity. This part is recommended for new design implementations and applications where RoHS compliance is mandated.

745076-3 (Similar Substitute - Legacy Compatibility)

The 745076-3 provides functional equivalence with one specification variance: contact finish thickness is specified as Flash rather than 30.0µin (0.76µm). This part carries RoHS non-compliant status. The 745076-3 is suitable for legacy system maintenance and applications where RoHS compliance is not required. Inventory availability is 1208 pieces. This part maintains all electrical and mechanical parameters necessary for direct functional substitution.

Selection Criteria Based on Compliance Requirements:

For applications requiring RoHS3 compliance, select 5745076-4. For legacy systems or applications without RoHS requirements, 745076-3 provides functional equivalence. All three parts (745076-4, 5745076-4, and 745076-3) are active products within the AMPLIMITE HD-20 series and maintain identical electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5745076-4 be used as a direct replacement for the 745076-4 in existing designs?

A: Yes. The 5745076-4 maintains complete electrical and mechanical equivalence with the 745076-4 across all critical parameters including voltage rating (125V), current rating (6A), connector configuration (9-position D-Sub receptacle), mounting type (through-hole solder), and operating temperature range (-55°C ~ 105°C). The primary difference is RoHS3 compliance status on the 5745076-4.

Q: What is the difference between the 745076-4 and 745076-3?

A: The 745076-4 and 745076-3 are functionally equivalent D-Sub receptacle connectors with identical electrical and mechanical specifications. The primary difference is contact finish thickness: the 745076-4 specifies 30.0µin (0.76µm) gold plating, while the 745076-3 specifies Flash gold plating. Additionally, the 745076-3 carries RoHS non-compliant status compared to the 745076-4 which is not applicable for RoHS classification.

Q: Are all three parts packaged identically?

A: Yes. The 745076-4, 5745076-4, and 745076-3 are all supplied in Tube packaging, suitable for standard component handling and storage procedures.

Q: Which substitute part should be selected for new product development?

A: The 5745076-4 is recommended for new product development due to ROHS3 compliance status and higher inventory availability (2283 pieces). This part ensures regulatory compliance and supports production scalability.

Q: Do these connectors require any special handling or storage conditions?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard component storage conditions are appropriate.

Q: Are the operating temperature ranges identical across all substitute parts?

A: Yes. All three parts (745076-4, 5745076-4, and 745076-3) operate across the identical temperature range of -55°C ~ 105°C and maintain UL94 V-0 material flammability rating.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes. The 745076-4, 5745076-4, and 745076-3 share identical mechanical dimensions, mounting footprints (through-hole configuration), and electrical characteristics. They are mechanically and electrically interchangeable within the same PCB design.

Q: What is the significance of the contact finish thickness difference between 745076-4 and 745076-3?

A: The 745076-4 specifies 30.0µin (0.76µm) gold plating thickness, while the 745076-3 specifies Flash plating. Both finishes provide adequate contact protection and conductivity for the 6A current rating and 125V voltage specification. The choice between these finishes depends on application-specific durability and mating cycle requirements.
