Key Parameters

Substitute Part Grouping Explanation

Substitute compatibility for the 243A11690X is determined by the following critical parameters:

1. Connector Type & Gender Configuration: The adapter must maintain D-Sub 26 HD female-to-male conversion functionality
2. Electrical Ratings: Minimum voltage rating of 100 V and current rating of 3 A
3. Contact Specifications: Gold finish contact system
4. Mounting Configuration: Free hanging (in-line) orientation
5. Mechanical Compatibility: Three-row D-Sub 26 HD pin arrangement
6. Environmental & Regulatory Compliance: UL94 V-0 flammability, RoHS3 compliance, IP20 ingress protection

A substitute part must satisfy all of these parameters to ensure functional and electrical equivalence.

Engineering Selection Recommendations

The 243A11690X is obsolete and requires substitution for new applications or system replacements. The Amphenol CONEC model 24-012303 is the manufacturer-recommended substitute and carries active product status, ensuring continued availability and support.

The 24-012303 provides equivalent connector configuration (D-Sub 26 HD female-to-male adapter) and is manufactured by the same supplier (Amphenol CONEC), providing design continuity. Active status ensures ongoing supply chain availability, which is critical for maintenance and production applications.

Selection of the 24-012303 as a direct replacement is supported by the manufacturer's explicit recommendation and shared connector specifications.
