Substitute Part Grouping Explanation

The substitute part 0761451607 is electrically and mechanically equivalent to the main part 0761450607 based on the following critical parameters:

Electrical Equivalence:

• Identical number of positions: 288
• Identical pitch: 0.053" (1.35mm)
• Identical contact layout: 96 differential pairs
• Identical voltage rating: 30V
• Identical contact finish and thickness: Gold, 30.0µin (0.76µm)

Mechanical Equivalence:

• Identical connector type: Header, Male Pins
• Identical mounting configuration: 18 rows × 16 columns
• Identical mounting type: Through Hole
• Identical termination method: Press-Fit
• Identical color: Black

Environmental and Compliance Equivalence:

• Identical operating temperature range: -55°C to 85°C
• Identical material flammability rating: UL94 V-0
• Identical RoHS status: ROHS3 Compliant

Engineering Selection Recommendations

The Molex 0761451607 is the direct equivalent for the obsolete 0761450607. Selection should be based on the following factors:

Product Status Consideration: The original part 0761450607 is obsolete. The substitute 0761451607 is active and maintains full production support from Molex, ensuring long-term availability and supply chain continuity.

Compliance and Certification: Both parts maintain identical compliance profiles: ROHS3 Compliant, UL94 V-0 flammability rating, and MSL 1 (Unlimited). The substitute includes REACH Unaffected certification, providing additional regulatory documentation.

Functional Equivalence: All electrical and mechanical parameters are identical, including connector geometry, pin configuration, contact specifications, and environmental ratings. Direct substitution is supported without design modification.

Packaging Consideration: The substitute is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

For new designs or system refreshes, specify the active part number 0761451607 to ensure ongoing supplier support and component availability.

Frequently Asked Questions (FAQ)

Q: Can the 0761451607 be used as a direct replacement for the 0761450607 in existing designs?

A: Yes. The parts are electrically and mechanically identical across all specified parameters. No PCB layout, schematic, or assembly process modifications are required. The substitute maintains the same 288-position configuration, 0.053" pitch, through-hole mounting, and press-fit termination.

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

A: The primary difference is product status. The 0761450607 is obsolete, while the 0761451607 is active. The substitute also specifies Tray packaging and includes REACH Unaffected certification. All functional and electrical specifications are identical.

Q: Are there any compatibility concerns with the packaging change?

A: The packaging difference (Tray vs. unspecified) affects logistics and handling but does not impact electrical or mechanical compatibility. Verify that Tray packaging meets your assembly and storage requirements.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 Compliant, UL94 V-0 rated, and have MSL 1 (Unlimited). They operate identically across the -55°C to 85°C temperature range and maintain the same 30V voltage rating.

Q: Why should I transition from the obsolete part to the active substitute?

A: The obsolete part 0761450607 has limited or no remaining inventory and no ongoing production support. The active part 0761451607 ensures continued availability, supply chain stability, and manufacturer support for technical issues or design questions.

Q: Are the contact specifications identical?

A: Yes. Both parts feature gold-plated contacts with 30.0µin (0.76µm) thickness, supporting the same 96 differential pair configuration and electrical performance.
