Engineering Selection Recommendations

The 5390378-7 is a direct functional equivalent to the 390378-7 and meets all electrical and mechanical specifications for interchangeable use. Both parts are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE .050 III series.

Key Differentiation Factors:

The primary distinction between the two parts is product status and regulatory compliance. The 390378-7 is classified as obsolete and carries RoHS non-compliant status. The 5390378-7 is an active product with RoHS Compliant certification, making it the preferred choice for new designs and applications subject to RoHS regulations.

For legacy system support and repair applications where the original 390378-7 is unavailable, the 5390378-7 provides full electrical and mechanical compatibility. The RoHS compliance of the 5390378-7 represents an improvement in environmental and regulatory standing without compromising functional performance.

Both parts share identical electrical ratings (1A current, 30V voltage), operating temperature range (-55°C ~ 85°C), contact materials (Phosphor Bronze with 30.0µin gold finish), and mechanical specifications (68 positions, 2 rows, 0.050 pitch, IDC termination).

Frequently Asked Questions (FAQ)

Q: Can the 5390378-7 be used as a direct replacement for the 390378-7?

A: Yes. The 5390378-7 meets all electrical and mechanical specifications of the 390378-7. Both connectors are 68-position D-Type receptacles with identical contact materials, finishes, current and voltage ratings, and operating temperature ranges. Direct substitution is supported without design modifications.

Q: What is the difference between the 390378-7 and 5390378-7?

A: The primary differences are product status and RoHS compliance. The 390378-7 is obsolete and RoHS non-compliant. The 5390378-7 is an active product with RoHS Compliant certification. All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns when substituting the 5390378-7 for the 390378-7?

A: No compatibility concerns exist. Both parts are manufactured by TE Connectivity AMP Connectors within the same AMPLIMITE .050 III series. They share identical connector styles, pin counts, pitch spacing, mounting configurations, and termination methods (IDC ribbon cable).

Q: Does the RoHS compliance of the 5390378-7 affect its performance compared to the 390378-7?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical or mechanical performance. Both parts deliver identical current capacity (1A), voltage rating (30V), contact finish (gold, 30.0µin), and operating temperature range (-55°C ~ 85°C).

Q: What is the shell size and pitch specification for these connectors?

A: Both the 390378-7 and 5390378-7 feature a 0.050 pitch with 0.100 row-to-row spacing. This specification defines the contact center-to-center distance and row separation, ensuring compatibility with standard IDC ribbon cable connectors and mating plugs designed for this pitch configuration.

Q: Are these connectors suitable for high-temperature applications?

A: Both connectors operate across the temperature range of -55°C to 85°C. Applications requiring operation outside this range require alternative connector designs with extended temperature specifications.

Q: What termination method do these connectors use?

A: Both the 390378-7 and 5390378-7 use IDC (Insulation Displacement Contact) termination for ribbon cable. This method allows direct connection to flat ribbon cables without stripping or crimping individual conductors.

Q: What is the current and voltage rating for these connectors?

A: Both connectors are rated for 1A current and 30V voltage. These ratings define the maximum electrical load each connector contact can safely handle in the specified application environment.
