Substitute Part Grouping Explanation

The Molex 0761453607 qualifies as a direct substitute for the 0761452607 based on strict parameter equivalence across all critical electrical and mechanical specifications. Substitution is valid because both parts share identical values for:

• Connector type, style, and position count (288-position Impact header, male pins, guide left)
• Physical array configuration (18 rows × 16 columns)
• Contact pitch (0.053" / 1.35mm)
• Differential pair layout (96 pairs)
• Mounting and termination method (through-hole, press-fit)
• Contact finish specification (gold, 30.0µin)
• Operating temperature range (-55°C to 85°C)
• Voltage rating (30V)
• Compliance certifications (UL94 V-0, ROHS3)
• Moisture sensitivity level (MSL 1)

The primary distinction is product status: the 0761452607 is obsolete, while the 0761453607 maintains active status with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761453607 is the direct equivalent for the obsolete 0761452607. Selection of the substitute part is based on:

• Complete electrical and mechanical parameter equivalence across all specified criteria
• Active product status with current manufacturing and distribution availability
• Identical compliance certifications (UL94 V-0, ROHS3)
• Maintained moisture sensitivity level (MSL 1) suitable for unlimited shelf life storage
• Packaging in tray format for the substitute part, which does not affect functional compatibility

No design modifications, PCB layout changes, or assembly procedure adjustments are required when transitioning from the obsolete part to the active substitute.
