Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0934447121 is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle housing (not plug)
• Number of Positions: 18 positions
• Number of Rows: 3-row configuration
• Contact Type: Male pin accommodation
• Mounting Type: Free hanging in-line orientation
• Contact Termination: Crimp connection method
• Fastening Type: Latch holder mechanism
• Color: Black housing
• Sealing Capability: IP68 rating or equivalent environmental protection

The identified substitute part AT16-18PB-K004 from Amphenol Sine Systems Corp satisfies all these parameters, establishing functional equivalence for direct replacement applications.

Engineering Selection Recommendations

The Amphenol Sine Systems Corp AT16-18PB-K004 is the designated manufacturer-recommended substitute for the obsolete Molex 0934447121. Both components maintain ROHS3 compliance and equivalent electrical and mechanical specifications across all critical substitution parameters.

The AT16-18PB-K004 offers the advantage of active product status, ensuring continued availability and manufacturing support. The specified operating temperature range of -55°C to 125°C and thermoplastic insulation material provide documented performance characteristics suitable for industrial applications. The moisture sensitivity level of 1 (unlimited) indicates standard handling requirements without special storage constraints.

Selection of the AT16-18PB-K004 is appropriate for direct replacement in applications where the original Molex 0934447121 was specified, provided that compatible male pin contacts are procured separately for both components.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol AT16-18PB-K004 directly replace the Molex 0934447121?

A: Yes. Both housings are 18-position receptacles with 3-row configuration, crimp termination, latch holder fastening, and black color. Mechanical and electrical compatibility is established across all specified parameters.

Q: Are contacts included with either housing?

A: No. Both the Molex 0934447121 and Amphenol AT16-18PB-K004 are supplied as housings without contacts. Male pin contacts must be procured separately and must be compatible with the 18-position, 3-row configuration.

Q: What is the significance of the AT16-18PB-K004 being "Active" versus the Molex part being "Obsolete"?

A: Active product status indicates the Amphenol part is currently manufactured and supported by the supplier. The obsolete status of the Molex part means it is no longer in production, making the active substitute essential for procurement continuity.

Q: Do both parts meet the same environmental sealing requirements?

A: Both parts provide sealed environmental protection. The Molex part specifies IP68 rating. The Amphenol part specifies sealed construction with cap (cover) included, providing equivalent environmental protection for in-line applications.

Q: What packaging differences exist between these parts?

A: The Molex 0934447121 packaging type is not specified in the technical data. The Amphenol AT16-18PB-K004 is supplied in box packaging. Packaging format does not affect functional compatibility.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The Amphenol part includes REACH Unaffected status. Both carry the same ECCN (EAR99) and HTSUS (8538.90.6000) classifications, indicating equivalent regulatory treatment.
