Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 745059-4 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for connector style, position count, row configuration, shell size, mounting type, termination method, contact finish, current and voltage ratings, operating temperature range, flammability rating, contact material, and dielectric material.

The primary distinction between the main part and its substitute relates to regulatory compliance status. The substitute part 5745059-4 maintains full electrical and mechanical compatibility while offering RoHS compliance, addressing procurement requirements where non-compliant components are restricted.

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 37
• Number of Rows: 2
• Shell Size: 4 (DC, C)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish: Gold at 30.0µin (0.76µm)
• Current Rating: 6A
• Voltage Rating: 125V
• Operating Temperature: -55°C ~ 105°C
• Material Flammability: UL94 V-0
• Contact Material: Phosphor Bronze
• Dielectric Material: Polyester

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 745059-4 and its substitute 5745059-4 are electrically and mechanically equivalent components within the AMPLIMITE HD-20 series. Both parts maintain identical specifications across all functional parameters including connector geometry, contact configuration, electrical ratings, and environmental operating conditions.

Selection between these parts is determined by regulatory compliance requirements:

745059-4 is appropriate for applications where RoHS compliance is not mandated or where existing non-compliant component inventories are acceptable.

5745059-4 is the required selection for applications subject to RoHS regulations, procurement policies requiring RoHS compliance, or end-use markets with mandatory compliance requirements. This part maintains full functional equivalence while meeting RoHS compliance standards.

Both parts are active products with established supply availability. The choice between them does not affect circuit performance, mechanical fit, or electrical characteristics.
