Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0934447131 must satisfy the following critical parameters to ensure functional equivalence:

• Connector Type: Receptacle housing
• Number of Positions: 18
• Number of Rows: 3
• Contact Type: Male Pin
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Color: Black
• RoHS Compliance: ROHS3 Compliant

The Amphenol Sine Systems Corp part AT16-18PC-K004 meets all these core substitution criteria. Both components are receptacle housings with identical position counts, row configurations, mounting methods, and termination approaches. Both maintain ROHS3 compliance and MSL 1 ratings, ensuring compatibility in applications requiring the original Molex component.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol Sine Systems Corp AT16-18PC-K004 is the designated manufacturer-recommended substitute for the obsolete Molex 0934447131. Both components maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility. The AT16-18PC-K004 carries active product status, providing assured long-term availability and supply chain continuity compared to the obsolete Molex part.

Selection of the Amphenol substitute is appropriate for applications requiring direct functional replacement of the Molex 0934447131 in 18-position rectangular connector housing configurations. The active product status of the AT16-18PC-K004 eliminates obsolescence risk in new designs and ongoing production environments.

Frequently Asked Questions (FAQ)

Q: What makes the Amphenol AT16-18PC-K004 a suitable substitute for the Molex 0934447131?

A: Both components are 18-position receptacle housings with identical row configurations (3 rows), mounting methods (free hanging in-line), termination approaches (crimp), and fastening mechanisms (latch holder). Both maintain ROHS3 compliance and MSL 1 ratings, satisfying all core substitution parameters.

Q: Does the Amphenol part have any additional features compared to the Molex original?

A: The AT16-18PC-K004 includes a cap (cover) and sealed features not specified in the original Molex part documentation. These additions provide enhanced protection without compromising functional compatibility.

Q: Are there packaging differences between these components?

A: The Molex 0934447131 packaging is not specified in available documentation. The Amphenol AT16-18PC-K004 is supplied in box packaging. Verify packaging requirements for your specific application and procurement process.

Q: Why is the Molex part classified as obsolete?

A: The Molex 0934447131 has reached end-of-life status. The Amphenol AT16-18PC-K004 is an active product with ongoing manufacturer support and supply availability.

Q: Can I use the Amphenol substitute in existing assemblies designed for the Molex part?

A: Yes. The Amphenol AT16-18PC-K004 maintains functional equivalence across all critical parameters: connector type, position count, row configuration, mounting method, termination type, and fastening mechanism. Existing mating components and contact sets designed for the Molex part are compatible with the Amphenol substitute.

Q: What is the significance of the MSL 1 rating for both components?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and require no special moisture control during storage or handling, simplifying logistics and inventory management.
