Engineering Selection Recommendations

The Molex 0761451604 is the direct functional equivalent of the 0761450604. Selection between these parts should be based on the following criteria:

For New Designs and Procurement: Use part number 0761451604. This part maintains active product status with Molex, ensuring long-term availability and supply chain stability. It carries identical electrical, mechanical, and environmental specifications, with ROHS3 compliance and UL94 V-0 flammability rating maintained.

For Legacy System Support: The 0761450604 remains functionally interchangeable with 0761451604 for existing applications. The obsolete status of the original part reflects manufacturing discontinuation rather than functional deficiency. Current inventory of 955 units of the original part is available; however, transition to the active substitute is recommended for future procurement cycles.

Packaging Consideration: The substitute part is supplied in tray packaging, whereas the original part is supplied in bulk. Verify that tray packaging is compatible with your assembly and handling processes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761451604 be used as a direct replacement for the 0761450604 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector type, position count, pitch, contact finish, termination method, and environmental ratings. The parts are functionally interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The 0761450604 is classified as obsolete, while the 0761451604 is active. The 0761451604 is supplied in tray packaging, whereas the 0761450604 is supplied in bulk. All electrical and mechanical specifications are identical.

Q: Why is the original part marked as obsolete?

A: Obsolete status indicates that Molex has discontinued manufacturing of the 0761450604. The substitute part 0761451604 represents the current active equivalent in the Impact 76145 series.

Q: Are there any compatibility concerns with the tray packaging of the substitute part?

A: Tray packaging is standard for active production parts. Verify that your assembly process and handling equipment are compatible with tray-packaged components. No electrical or mechanical compatibility issues exist between the two packaging formats.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0761450604 and 0761451604 are ROHS3 compliant, carry UL94 V-0 flammability rating, and maintain identical environmental specifications including operating temperature range (-55°C ~ 85°C) and voltage rating (30V).

Q: What is the contact layout configuration for these connectors?

A: Both parts feature 96 differential pairs within the 288-position header, arranged in an 18 row × 16 column configuration with 0.053" (1.35mm) pitch.
