Substitute Part Grouping Explanation

The Molex 0761655608 qualifies as a direct substitute for the 0761654608 based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, style, and orientation remain unchanged (Header, Male Pins, Impact, Guide Right)
• Position count and matrix configuration are identical (144 positions, 9×16 layout)
• Pitch specification matches exactly (0.053" / 1.35mm)
• Contact finish and voltage rating are equivalent (Gold, 30V)
• Operating temperature range encompasses the original specification (-55°C to 85°C)
• Mounting and termination methods are identical (Through Hole, Press-Fit)
• Compliance certifications meet or exceed the original (UL94 V-0, ROHS3)

The primary distinction between these parts is product status: the 0761654608 is obsolete, while the 0761655608 maintains active production status. Packaging differs (the substitute is supplied in Tray format), which does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761655608 is the appropriate selection for applications currently using or requiring the 0761654608. This substitution is supported by:

• Identical electrical specifications and mechanical dimensions
• Equivalent compliance certifications (UL94 V-0, ROHS3)
• Active production status ensuring supply chain continuity
• Identical contact configuration and differential pair layout (48 pairs)
• Matching operating temperature and voltage ratings

The obsolete status of the 0761654608 makes the 0761655608 the standard replacement for new designs and ongoing production requirements. No design modifications are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the 0761655608 be used as a direct replacement for the 0761654608 in existing designs?

A: Yes. All electrical, mechanical, and dimensional specifications are identical. No PCB layout or assembly modifications are required.
