TE Connectivity 745458-2 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745458-2 is a 25-position D-Sub receptacle connector with female sockets, designed for through-hole mounting applications. This connector is part of the AMPLIMITE HDP-20 series and features press-fit termination with gold-plated copper alloy contacts. The part maintains active product status and is currently available in inventory.

Alternative equivalent parts are necessary to address supply chain flexibility, compliance requirements, and manufacturing continuity. Substitute parts maintain identical electrical and mechanical specifications while offering different regulatory compliance profiles or enhanced availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 745458-2 and the equivalent part 5745458-2 is based on strict electrical and mechanical parameter matching. Both connectors share identical specifications across all critical functional parameters:

Key Parameters Determining Substitutability:

• Connector type, style, and position count (25-position D-Sub receptacle)
• Physical mounting configuration (through-hole, vertical press-fit)
• Contact specifications (gold-plated copper alloy, signal type)
• Mechanical interface (shell size 3, female screwlock flange)
• Environmental ratings (UL94 V-0, operating temperature -55°C to 105°C)
• Dielectric material composition (polyamide nylon, glass-filled)

The primary distinction between these parts lies in regulatory compliance status and inventory availability, not in functional or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select part number 5745458-2. This variant maintains full electrical and mechanical compatibility with 745458-2 while meeting ROHS3 compliance requirements. The part is designated as REACH Affected, indicating compliance with European chemical substance regulations.

For Non-Compliant or Legacy Applications: Part number 745458-2 remains suitable for applications without RoHS compliance mandates. This variant carries RoHS non-compliant status with vendor-undefined REACH status.

For Supply Chain Continuity: Part number 5745458-2 offers higher current inventory availability (1114 pieces versus 695 pieces), supporting extended production schedules and reducing procurement lead times.

Both parts share identical functional specifications, mechanical interfaces, and environmental performance characteristics. Selection between these equivalents depends solely on regulatory compliance requirements and inventory availability constraints.

Frequently Asked Questions (FAQ)

Q: Are 745458-2 and 5745458-2 electrically interchangeable?

A: Yes. Both connectors feature identical electrical specifications including 25-position configuration, gold-plated copper alloy contacts, signal contact type, and operating temperature range of -55°C to 105°C.

Q: Are these connectors mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications: through-hole mounting, press-fit termination, shell size 3 (DB, B), female screwlock flange with 4-40 fasteners, and black polyamide nylon dielectric material.

Q: What is the primary difference between these two part numbers?

A: The primary differences are regulatory compliance status and inventory availability. Part 5745458-2 is ROHS3 compliant and REACH Affected, while 745458-2 is RoHS non-compliant with vendor-undefined REACH status. Part 5745458-2 also has higher inventory availability.

Q: Can I use 5745458-2 as a direct replacement for 745458-2 in existing designs?

A: Yes. The parts are functionally and mechanically equivalent. Selection should be based on regulatory compliance requirements for your application and target market.

Q: What does the press-fit termination mean?

A: Press-fit termination indicates that contacts are inserted into the connector body using mechanical pressure rather than soldering. This termination method is suitable for through-hole printed circuit board applications.

Q: Are both parts rated for the same environmental conditions?

A: Yes. Both connectors operate across the identical temperature range of -55°C to 105°C and carry the same UL94 V-0 flammability rating for the dielectric material.

Q: What is the significance of the shell size designation "3 (DB, B)"?

A: Shell size 3 designates a standard D-Sub connector footprint. The DB designation indicates a 25-position configuration, and B indicates the specific shell profile. This ensures mechanical compatibility with standard D-Sub mating connectors and backshells.

Q: Does packaging differ between these parts?

A: No. Both parts are supplied in bulk packaging format.
