TE Connectivity 745078-6 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745078-6 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 745078-6 serves as a standard interface component in applications requiring robust D-shaped connector solutions with vertical mounting orientation and mating-side screwlock features. Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, inventory optimization, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 745078-6 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Connector style (D-Sub)
• Connector type (Receptacle, Female Sockets)
• Number of positions (25)
• Number of rows (2)
• Shell size and connector layout (3 / DB, B)
• Mounting type (Through Hole)
• Termination method (Solder)
• Flange feature (Mating Side, Female Screwlock 4-40)
• Contact type (Signal)
• Contact finish and thickness (Gold, 30.0µin)
• Current rating (6A)
• Voltage rating (125V)
• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)
• Contact material (Phosphor Bronze)
• Dielectric material (Polyester)
• Color (Black)
• Series (AMPLIMITE HD-20)

Parts meeting all these criteria are classified as direct substitutes and are electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5745078-6 is a direct substitute for the 745078-6 based on complete electrical and mechanical parameter equivalence. Both parts are active products from the AMPLIMITE HD-20 series manufactured by TE Connectivity AMP Connectors.

The primary distinction between these parts is the RoHS compliance status. The 745078-6 is listed as "Not applicable" for RoHS, while the 5745078-6 is ROHS3 compliant. For applications requiring RoHS3 compliance, the 5745078-6 is the appropriate selection. Both parts maintain identical electrical ratings (6A at 125V), operating temperature range (-55°C ~ 105°C), and material specifications (UL94 V-0 flammability rating, phosphor bronze contacts with 30.0µin gold finish, polyester dielectric).

Both parts are subject to REACH regulations and carry the same ECCN (EAR99) and HTSUS classification (8536.69.4040). The connector layout, mounting configuration, and termination method are identical across both parts, ensuring direct interchangeability in through-hole solder applications.

Frequently Asked Questions (FAQ)

Q: Are the 745078-6 and 5745078-6 electrically interchangeable?

A: Yes. Both parts have identical electrical specifications including 6A current rating, 125V voltage rating, and -55°C ~ 105°C operating temperature range. The contact material (phosphor bronze), contact finish (gold at 30.0µin thickness), and dielectric material (polyester) are identical.

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

A: The primary difference is RoHS compliance status. The 5745078-6 is ROHS3 compliant, while the 745078-6 is listed as "Not applicable" for RoHS. All other electrical, mechanical, and material specifications are identical.

Q: Can I use the 5745078-6 in place of the 745078-6 in my design?

A: Yes. The 5745078-6 is a direct mechanical and electrical substitute. It has the same connector layout (25-position, 2-row, shell size 3), mounting type (through-hole), termination method (solder), and flange configuration (mating side female screwlock 4-40).

Q: Are both parts available in the same packaging?

A: Yes. Both the 745078-6 and 5745078-6 are supplied in tube packaging.

Q: Do these connectors have the same mating interface?

A: Yes. Both parts feature the same D-Sub receptacle configuration with female sockets, mating-side female screwlock (4-40), and identical shell size and layout (3 / DB, B).

Q: What is the contact finish specification for these connectors?

A: Both parts have gold-plated contacts with a finish thickness of 30.0µin (0.76µm).

Q: Are there any temperature or environmental limitations?

A: Both parts operate across the same temperature range of -55°C to 105°C and carry a UL94 V-0 material flammability rating. Both are subject to REACH regulations.

Q: Which part should I specify for new designs?

A: For new designs requiring RoHS3 compliance, specify the 5745078-6. For applications without RoHS requirements, either part is suitable based on availability and supply chain considerations.
