• Connector Type and Style: Header with male pins, Impact series design
• Position Count and Matrix: 72 positions in 9×8 configuration
• Pitch Specification: 0.053" (1.35mm) center-to-center spacing
• Mounting and Termination: Through-hole PCB mounting with press-fit termination
• Electrical Ratings: 30V voltage rating and contact finish specifications
• Environmental Compliance: UL94 V-0 flammability, ROHS3 compliance, and MSL 1 rating

The substitute part 0761651806 maintains identical electrical, mechanical, and environmental specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761651806 is a direct functional equivalent to the 0761650806. Both parts are manufactured by Molex within the Impact 76165 series and share identical electrical, mechanical, and environmental specifications. The primary distinction is product status: the 0761650806 is obsolete, while the 0761651806 maintains active status with current manufacturing support.

Selection of the 0761651806 is supported by:

• Full compliance with ROHS3 environmental regulations
• Maintained UL94 V-0 flammability certification
• Identical voltage and temperature operating parameters
• Equivalent contact finish and termination specifications
• Active product status ensuring long-term availability and supply chain continuity

The packaging difference (bulk versus tray) does not affect functional compatibility and represents a logistical consideration only.

Frequently Asked Questions (FAQ)

Q: Are the 0761650806 and 0761651806 mechanically interchangeable?
