Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 980-015-030-121 is determined by the following critical parameters:

• Number of Positions: Must be 15
• Compatible Shell Size: Must be A
• Compatible D-Sub Size: Must support 15pos and HD26pos
• Accessory Type: Must be Two Piece Backshell
• Shielding: Must be Shielded
• Material Composition: Must be Metal, Zinc Alloy
• Plating: Must be Nickel over Copper
• Cable Type: Must be Round

The primary differentiator for the identified substitute is the cable exit angle. The 980-015-030-121 features a 180° exit, while substitute options may feature alternative exit angles. Substitution is valid when the mechanical and electrical interface parameters remain constant and the application permits the alternative cable exit configuration.

Parameter Comparison

Engineering Selection Recommendations

The 981-015-030R121 serves as the active equivalent for the obsolete 980-015-030-121. Both components share identical mechanical and electrical interface specifications, including position count, shell size, D-Sub compatibility, shielding, material composition, and plating.

The primary distinction is the cable exit angle: the 981-015-030R121 features a 90° exit compared to the 180° exit of the original part. Selection between these variants depends on the specific cable routing requirements of the application.

An additional advantage of the 981-015-030R121 is its ROHS3 compliance status, compared to the non-compliant status of the 980-015-030-121. For new designs or systems subject to RoHS regulations, the 981-015-030R121 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 981-015-030R121 directly replace the 980-015-030-121?

A: The 981-015-030R121 is mechanically and electrically compatible with the same D-Sub connector systems. The primary consideration is the cable exit angle: 90° versus 180°. Substitution is valid if the application's cable routing accommodates the 90° exit configuration.

Q: What is the significance of the cable exit angle difference?

A: The cable exit angle determines the physical orientation of the cable relative to the connector body. A 180° exit directs the cable straight back from the connector, while a 90° exit directs it perpendicular. The choice depends on the available space and cable routing path in the assembly.

Q: Are there any compliance differences between these parts?

A: Yes. The 980-015-030-121 is RoHS non-compliant, while the 981-015-030R121 is ROHS3 compliant. For applications subject to RoHS regulations or environmental compliance requirements, the 981-015-030R121 is the required selection.

Q: Do both parts use the same material and plating?

A: Yes. Both components are constructed from metal zinc alloy with nickel over copper plating, ensuring equivalent electrical and mechanical performance in shielded applications.

Q: What is the inventory status of the substitute part?

A: The 981-015-030R121 is currently active with 1,041 pieces in stock, compared to the obsolete status of the 980-015-030-121 with 897 pieces available.
