TE Connectivity 745078-5 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745078-5 is a 25-position D-Sub receptacle connector with female sockets, designed for through-hole solder termination applications. This connector belongs to the AMPLIMITE HD-20 series and is classified as an active product. The 745078-5 operates within industrial and commercial environments requiring reliable signal transmission across multiple positions with standardized D-Sub shell geometry.

Substitute parts become necessary when the original part number reaches end-of-life status, inventory constraints occur, or when design revisions require updated compliance certifications such as RoHS3 compliance. The substitute part maintains functional and mechanical equivalence while addressing regulatory and availability requirements.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 745078-5 with part number 5745078-5 is based on strict equivalence across all electrical and mechanical parameters. Both connectors maintain identical specifications for:

Electrical Parameters: 25-position configuration, 6A current rating, 125V voltage rating, signal contact type, and phosphor bronze contact material with gold flash finish.

Mechanical Parameters: D-Sub shell size 3 (DB, B) layout, through-hole mounting, solder termination, female screwlock flange feature (4-40), and polyester dielectric material.

Environmental Parameters: Operating temperature range of -55°C to 105°C, UL94 V-0 flammability rating, and moisture sensitivity level 1 (unlimited).

Series Designation: Both parts belong to the AMPLIMITE HD-20 series, ensuring design compatibility and interchangeability.

The primary distinction between these parts is regulatory compliance status. The substitute part 5745078-5 carries RoHS3 compliance certification, whereas the original 745078-5 is RoHS non-compliant. Both parts maintain REACH affected status and EAR99 ECCN classification.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: The substitute part 5745078-5 is the recommended selection for all new applications and procurement activities.
