Substitute Part Grouping Explanation

Substitute parts for the Molex 1600733115 are determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: All substitutes are receptacle housings with female socket contacts
Electrical Interface: 3-position, 0.177" (4.50mm) pitch configuration
Mechanical Compatibility: Free-hanging in-line mounting with crimp termination and latch holder fastening
Environmental Specifications: Operating temperature range of -40°C to 125°C, sealed design with CPA feature

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full ROHS3 compliance. Selection between the primary part (1600733115) and substitutes should be based on:

Inventory Availability: Part 1600733105 (black) offers the highest stock level at 11,514 units. Parts 1600733107 and 1600733116 (gray) provide 4,012 and 1,801 units respectively. The primary part 1600733115 (gray) maintains 743 units in stock.

Color Specification: The primary part and substitutes 1600733106, 1600733107, and 1600733116 are gray. Substitute 1600733105 is black. Color selection depends on application requirements and assembly documentation.

Packaging Format: The primary part 1600733115 is supplied in standard packaging. Substitutes 1600733105, 1600733106, 1600733107, and 1600733116 are available in bulk packaging, which may affect procurement logistics and handling procedures.

All parts share identical electrical performance, mechanical fit, and environmental ratings within the MX150 series specification.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically interchangeable with the Molex 1600733115?

A: Yes. All substitute parts maintain identical connector type (receptacle), contact configuration (3-position female socket), pitch (0.177" / 4.50mm), termination method (crimp), and fastening mechanism (latch holder). They are fully interchangeable from an electrical and mechanical standpoint.

Q: Does the color difference between gray and black parts affect functionality?

A: No. Color is a cosmetic specification only and does not affect electrical performance, mechanical compatibility, or environmental ratings. Selection should be based on assembly documentation or application requirements.

Q: What is the difference between standard and bulk packaging?

A: The primary part 1600733115 uses standard packaging. Substitute parts 1600733105, 1600733106, 1600733107, and 1600733116 are supplied in bulk packaging. This affects order quantities, handling procedures, and storage requirements but does not impact component performance.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the primary part 1600733115 and all substitutes, are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: Can I mix gray and black housings in the same assembly?

A: Functionally, yes. However, assembly documentation and design specifications should be consulted to determine if color consistency is required for your application.

Q: What is Connector Position Assurance (CPA)?

A: CPA is a feature that ensures proper mating alignment and prevents incomplete connections. All listed parts include this feature.
