Substitute Part Grouping Explanation

Substitute parts for the 243A12920X are determined by equivalence in the following critical parameters:

• Connector Type: Both main and substitute parts must provide D-Sub 9 Pin Female to D-Sub 9 Pin Male adapter functionality
• Category: D-Sub, D-Shaped Connectors
• Mounting Configuration: Free-hanging (in-line) style
• Connector Style: Connector Saver adapter classification
• Electrical Ratings: Minimum voltage rating of 100 V and current rating of 7.5 A
• Operating Temperature: Capable of -25°C to +105°C performance range
• Compliance Standards: RoHS3 compliance and UL94 V-0 flammability rating

The primary substitute identified is the Amphenol CONEC 24-503333, which provides equivalent D-Sub adapter functionality with an Active product status, ensuring continued availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: The Amphenol CONEC 24-503333 is the designated equivalent substitute for the obsolete 243A12920X model.

Justification:

• Both parts originate from the same manufacturer (Amphenol CONEC), ensuring design and performance consistency
• The 24-503333 maintains Active product status, guaranteeing long-term supplier support and inventory availability
• Both parts provide identical functional connectivity: D-Sub 9 Pin Female to D-Sub 9 Pin Male adapter capability
• The substitute part meets all mandatory electrical ratings and environmental compliance requirements specified for the main part
• ROHS3 compliance certification ensures regulatory alignment with current environmental standards

Selection Criteria: Choose 24-503333 when the 243A12920X is unavailable. The active status of the substitute ensures no supply chain disruption for new designs or replacement applications requiring D-Sub 9 Pin adapter connectivity.
