Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761550113 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins, Impact series)
• Position count and matrix configuration (120 positions, 12×10 layout)
• Pitch specification (0.053" / 1.35mm)
• Mounting method (Through Hole)
• Termination technology (Press-Fit)
• Contact finish and material specifications (Gold plating, UL94 V-0)
• Electrical ratings (30V, operating temperature -55°C to 85°C)
• Compliance certifications (ROHS3, MSL 1)

The substitute part Molex 0761551113 meets all these criteria and represents a direct functional equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761551113 is the direct substitute for the obsolete 0761550113. Both parts are manufactured by Molex within the Impact 76155 series and share identical electrical, mechanical, and compliance specifications. The primary distinction is product status: the 0761551113 is currently active in production, ensuring long-term availability and supply chain continuity.

The 0761551113 is packaged in trays, which provides superior protection and handling characteristics compared to bulk packaging. Both parts maintain ROHS3 compliance and MSL 1 rating, confirming suitability for standard storage and assembly environments without moisture sensitivity constraints.

For applications currently using the 0761550113, direct substitution with the 0761551113 requires no design modifications, PCB layout changes, or electrical parameter adjustments. The parts are mechanically and electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the 0761551113 be used as a direct replacement for the 0761550113 without PCB modifications?
