Key Parameters

Substitute Part Grouping Explanation

Substitution of the 974-009-010-011 is determined by strict equivalence across the following critical parameters:

• Number of Positions: 9
• Compatible Shell Size: E
• Compatible D-Sub Size: 9pos and HD15pos
• Cable Exit Angle: 40°
• Cable Type: Round
• Shielding: Unshielded
• Material: Acrylonitrile Butadiene Styrene (ABS)
• Color: Black
• Hardware: Assembly Hardware, Strain Relief
• Mating Screws: 4-40

The substitute part 974-009-010R011 maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The 974-009-010R011 is the direct active equivalent of the obsolete 974-009-010-011. Selection of the substitute part is based on:

• Identical mechanical and electrical specifications across all connector parameters
• Active product status ensuring ongoing availability and supply chain support
• ROHS3 compliance of the substitute part, providing regulatory alignment for new designs and applications subject to RoHS requirements
• MSL rating of 1 (Unlimited) for the substitute part, indicating superior moisture handling characteristics

For applications where RoHS compliance is not a requirement, both parts are functionally equivalent. For new designs or applications requiring regulatory compliance, the 974-009-010R011 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the 974-009-010-011 and 974-009-010R011 mechanically interchangeable?

A: Yes. Both parts share identical specifications for number of positions (9), compatible shell size (E), compatible D-Sub sizes (9pos and HD15pos), cable exit angle (40°), cable type (round), shielding (unshielded), material (ABS), color (black), hardware configuration, and mating screw size (4-40).

Q: What is the primary reason to transition from 974-009-010-011 to 974-009-010R011?

A: The 974-009-010-011 is classified as obsolete. The 974-009-010R011 is the active equivalent part, ensuring continued availability and supply chain support.
