Key Parameters

Substitute Part Grouping Explanation

The substitute part 970-009-030R121 is classified as a direct equivalent based on the following critical parameters:

• Electrical Compatibility: Identical 9-position configuration with matching shielding specifications
• Mechanical Compatibility: Same shell size (E), cable exit angle (180°), and compatible D-Sub sizes (9pos and HD15pos)
• Physical Properties: Identical material composition (Metal, Zinc), plating (Nickel over Copper), and hardware specifications (4-40 mating screws)
• Functional Equivalence: Two-piece backshell design with identical cable type (round) and assembly hardware

The primary distinction between the main part and substitute is product status and compliance certification, not functional or mechanical capability.

Parameter Comparison
