Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0391001502 is determined by the following critical parameters:

• Terminal Block Type: Must be Eurostyle Terminal Strip
• Number of Circuits: Must be 2
• Number of Wire Entries: Must be 4
• Top Termination: Must be Screws
• Bottom Termination: Must be Closed
• Barrier Type: Must be Enclosed
• Voltage Rating: Must be 600V minimum
• Current Rating: Must be 63A minimum
• Wire Gauge Compatibility: Must support 6-14 AWG
• Operating Temperature: Must be 100°C minimum
• Insulation Material: Must be Polyamide (PA66), Nylon 6/6
• Flammability Rating: Must be UL94 V-2 minimum
• Mounting Type: Must support Chassis and Panel mounting

The TE Connectivity AMP Connectors part number 1776315-2 meets all substitution criteria. While the pitch differs slightly (0.571" versus 0.591"), both parts maintain identical electrical ratings, termination methods, circuit configuration, and material specifications. The pitch variance of 0.020" (0.50mm) falls within acceptable mechanical tolerance for Eurostyle terminal strip applications where mounting hole patterns and connector footprints are designed to accommodate standard pitch variations within this product family.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1776315-2 is the qualified substitute for the obsolete Molex 0391001502. Selection is supported by the following factors:

Product Status: The Molex part is obsolete, while the TE Connectivity equivalent is active and currently in production, ensuring long-term availability and supply chain continuity.

Electrical Compliance: Both parts meet identical voltage (600V) and wire gauge (6-14 AWG) requirements. The TE Connectivity part provides a 2A current rating advantage (65A versus 63A), offering improved margin for high-current applications.

Regulatory Compliance: Both parts carry UL94 V-2 flammability ratings and are classified under the same HTSUS code (8536.90.4000). The TE Connectivity part maintains RoHS compliance status, meeting current environmental regulations.

Material and Thermal Specifications: Identical insulation material (Polyamide PA66, Nylon 6/6) and operating temperature rating (100°C) ensure thermal and chemical compatibility in existing applications.

Termination and Mounting: Screw-type top termination, closed bottom termination, and chassis/panel mounting compatibility are preserved, allowing direct functional replacement in existing designs.

Mechanical Consideration: The 0.020" (0.50mm) pitch difference represents a minor dimensional variance within standard Eurostyle terminal strip tolerance ranges and does not affect electrical performance or mounting compatibility in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1776315-2 directly replace the Molex 0391001502 in existing assemblies?

A: Yes. Both parts share identical electrical ratings (600V, 63A minimum), termination methods (screw-type), circuit configuration (2 circuits, 4 wire entries), and insulation materials (PA66 Nylon 6/6). The 0.020" pitch difference falls within standard mechanical tolerance for Eurostyle terminal strip applications.

Q: What is the significance of the pitch difference between these parts?

A: The Molex part features 0.591" (15.00mm) pitch, while the TE Connectivity substitute uses 0.571" (14.50mm) pitch. This 0.50mm variance is a standard dimensional tolerance within the Eurostyle terminal strip product family and does not affect electrical performance or mounting hole compatibility in typical chassis and panel applications.

Q: Are there any compliance or certification differences between these parts?

A: Both parts meet UL94 V-2 flammability requirements and are classified under identical HTSUS codes. The TE Connectivity part maintains active RoHS compliance status, while the Molex part carries ROHS3 compliance. Both are EAR99 classified for export purposes.

Q: Why is the Molex part obsolete?

A: The Molex 0391001502 has been discontinued and is no longer in production. The TE Connectivity 1776315-2 represents the active equivalent within the Eurostyle terminal strip product line, ensuring continued availability for new designs and legacy system support.

Q: Does the TE Connectivity part support the same wire gauge range?

A: Yes. Both parts accommodate 6-14 AWG wire gauges, ensuring compatibility with existing wiring specifications and installation practices.

Q: What is the difference in terminal screw finish between these parts?

A: The Molex part uses standard zinc finish, while the TE Connectivity part uses zinc trivalent finish. Trivalent zinc provides enhanced corrosion resistance and is the current industry standard for terminal screw applications.

Q: Are there any packaging differences?

A: The Molex part is listed with unspecified packaging, while the TE Connectivity part is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.
