Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0391000810 is determined by the following critical parameters:

• Circuit Configuration: 10 circuits with 0.315" (8.00mm) pitch and 2-row arrangement
• Termination Method: Screw-based top termination with closed bottom termination
• Barrier Type: Enclosed barrier design
• Wire Gauge Compatibility: 12-22 AWG acceptance
• Insulation Material: Polyamide (PA66) / Nylon 6/6
• Flammability Rating: UL94 V-2
• Mounting Type: Chassis and panel mounting capability

The TE Connectivity AMP Connectors part 1-1776293-0 meets these core substitution criteria. While electrical ratings differ (30A vs. 20A current; 250V vs. 600V voltage), the mechanical and functional parameters align with the original specification, allowing this part to function as a direct substitute in applications where the original component is no longer available.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-1776293-0 is the designated substitute for the obsolete Molex 0391000810. Selection is based on:

• Mechanical Compatibility: Identical circuit count, pitch, row configuration, and mounting interface ensure direct physical replacement without PCB or chassis modifications.
• Functional Equivalence: Matching wire gauge acceptance (12-22 AWG), termination method (screw-based), and barrier design preserve the original electrical interface.
• Compliance Alignment: Both parts maintain ROHS3 compliance and UL94 V-2 flammability rating, ensuring regulatory continuity.
• Active Product Status: The TE Connectivity part is currently in active production with confirmed inventory availability (2292 pcs), providing supply chain reliability compared to the obsolete Molex component.

Application-specific voltage and current requirements must be evaluated against the substitute part's ratings (250V, 30A) to confirm suitability for the intended circuit.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1776293-0 be used as a direct replacement for the Molex 0391000810?

A: Yes. Both parts share identical mechanical dimensions, circuit configuration (10 circuits at 0.315" pitch), wire gauge compatibility (12-22 AWG), and mounting interface. Physical and functional substitution is direct.

Q: What are the key differences between these two parts?

A: The primary differences are electrical ratings and product status. The Molex part is rated 20A at 600V and is obsolete. The TE Connectivity substitute is rated 30A at 250V and is in active production. Operating temperature range also differs: the TE part extends to -35°C minimum versus the Molex part's unspecified minimum.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts are ROHS3 compliant and carry UL94 V-2 flammability certification. Regulatory compliance is maintained with this substitution.

Q: What should be verified before implementing this substitute?

A: Confirm that the application's voltage requirement does not exceed 250V and current demand does not exceed 30A. The TE Connectivity part's lower voltage rating (250V vs. 600V) is the primary constraint for high-voltage applications.

Q: Is the TE Connectivity part available in the same packaging as the original?

A: The TE Connectivity part is supplied in bulk packaging, whereas the original Molex part packaging specification is not defined in the available data. Verify packaging requirements for your procurement process.
