TE Connectivity 745116-1 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745116-1 is a 50-position D-Sub receptacle connector with female sockets, designed for through-hole, right-angle solder termination applications. This connector belongs to the AMPLIMITE HDP-20 series and features a shell size 5 (DD, D) configuration with mounting brackets and standard 4-40 screws on the mating side flange.

The 745116-1 carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing design support, maintenance, and procurement activities. The substitute part 5745116-1 provides an active-status alternative with identical electrical and mechanical specifications while offering improved compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub receptacle connectors is determined by strict equivalence across electrical and mechanical parameters. The 745116-1 and its substitute 5745116-1 share identical specifications in the following critical categories:

Electrical Parameters: Current rating (6A), voltage rating (125V), contact material (phosphor bronze), contact finish (gold), and operating temperature range (-55°C to 105°C) are identical across both parts.

Mechanical Parameters: Connector style (D-Sub), connector type (receptacle, female sockets), number of positions (50), number of rows (3), shell size (5, DD, D), mounting type (through hole, right angle), termination method (solder), flange feature (mating side with 4-40 screws), backset spacing (0.545"/13.84mm), shell material and finish (steel, tin plated), and material flammability rating (UL94 V-0) are identical.

Environmental Parameters: Moisture sensitivity level (1, unlimited) and ECCN classification (EAR99) are identical.

The primary distinction between these parts lies in product status (obsolete versus active) and compliance certifications, with the substitute offering improved RoHS compliance and REACH status.

Parameter Comparison

Engineering Selection Recommendations

The 5745116-1 substitute part is functionally equivalent to the 745116-1 across all electrical and mechanical parameters. Selection between these parts should be based on the following criteria:

For New Designs and Active Programs: The 5745116-1 is the appropriate selection due to its active product status, RoHS compliance, and defined REACH status. These characteristics ensure long-term availability, regulatory alignment, and supply chain continuity.

For Legacy System Support and Maintenance: The 745116-1 remains available with 1115 pieces in stock. However, the obsolete product status indicates limited future availability. Transition planning to the 5745116-1 is recommended for ongoing support requirements.

Compliance Considerations: The 5745116-1 offers RoHS compliance and REACH unaffected status, whereas the 745116-1 is RoHS non-compliant with vendor-undefined REACH status. Applications subject to RoHS or REACH regulatory requirements must use the 5745116-1.

Dielectric Material Difference: The 745116-1 uses thermoplastic dielectric material, while the 5745116-1 uses polyamide (PA) nylon with glass filling. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range. The glass-filled polyamide in the 5745116-1 provides enhanced mechanical and thermal stability.

Frequently Asked Questions (FAQ)

Q: Are the 745116-1 and 5745116-1 pin-compatible?

A: Yes. Both connectors feature identical 50-position, 3-row configurations with shell size 5 (DD, D) and 0.545" (13.84mm) backset spacing. Pin-to-pin compatibility is complete.

Q: Can the 5745116-1 be used as a direct replacement for the 745116-1 in existing assemblies?

A: Yes. The 5745116-1 is electrically and mechanically equivalent. Both connectors support 6A current at 125V, operate across -55°C to 105°C, and feature identical solder termination, mounting configuration, and flange specifications.

Q: What is the significance of the dielectric material difference?

A: The 745116-1 uses thermoplastic dielectric material, while the 5745116-1 uses glass-filled polyamide (PA) nylon. Both materials meet UL94 V-0 flammability standards and support the full operating temperature range. The glass-filled polyamide provides improved mechanical rigidity and thermal performance.

Q: Why is the 745116-1 listed as obsolete?

A: Obsolete status indicates that TE Connectivity has discontinued active production and support for this part number. The 5745116-1 represents the active continuation of this connector family.

Q: Are there packaging differences between these parts?

A: The 745116-1 packaging is not specified in available documentation. The 5745116-1 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Which part should be specified for new designs?

A: The 5745116-1 should be specified for new designs. It offers active product status, RoHS compliance, and defined REACH status, ensuring regulatory alignment and supply chain continuity.

Q: Are both parts suitable for high-reliability applications?

A: Both connectors meet UL94 V-0 flammability requirements and support the full -55°C to 105°C operating range. The 5745116-1 offers improved compliance certifications (RoHS compliant, REACH unaffected) and glass-filled dielectric material, making it the preferred choice for high-reliability applications.

Q: What is the current inventory status?

A: The 745116-1 has 1115 pieces in stock (new original). The 5745116-1 has 1172 pieces in stock (new original, bulk packaging). Inventory levels are subject to change; confirm availability with your supplier.
