Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 979-015-020-121 is determined by strict equivalence across the following critical parameters:

• Number of Positions: 15 (exact match required)
• Compatible Shell Size: A (exact match required)
• Compatible D-Sub Size: 15pos and HD26pos (exact match required)
• Cable Exit Angle: 180° (exact match required)
• Shielding Configuration: Shielded (exact match required)
• Accessory Type: Two Piece Backshell (exact match required)
• Cable Type: Round (exact match required)
• Material and Plating: Plastic with Metallized coating, Chrome plating (exact match required)
• Hardware Configuration: Assembly Hardware, Grommets with 4-40 Mating Screws (exact match required)

The substitute part 979-015-020R121 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 979-015-020R121 is the direct substitute for the obsolete 979-015-020-121. Both parts are manufactured by NorComp Inc. and share identical mechanical and electrical specifications across all critical parameters.

The primary distinction between the two parts is product status and regulatory compliance. The 979-015-020-121 is obsolete and RoHS non-compliant, while the 979-015-020R121 is active and ROHS3 compliant. For new designs or systems requiring regulatory compliance with modern environmental standards, the 979-015-020R121 is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.
