• Number of positions: 16
• Pitch specification: 0.100" (2.54mm)
• Connector series: AMPMODU Mod II
• Mounting technology: Through Hole
• Termination method: Solder
• Contact material: Copper Alloy
• Insulation material: Liquid Crystal Polymer (LCP)
• HTSUS classification: 8536.69.4040
• ECCN classification: EAR99
• MSL rating: 1 (Unlimited)

The substitute part 5-146258-8 maintains functional and mechanical compatibility while providing improved product status (Active vs. Obsolete) and enhanced regulatory compliance (RoHS Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: Select 5-146258-8 as the primary component choice. This part maintains active product status with TE Connectivity, ensuring long-term availability and supply chain stability. The RoHS Compliant designation aligns with current regulatory requirements and environmental standards applicable to electronic component manufacturing and distribution.

For Legacy System Maintenance: The original 103777-8 remains available in inventory (1076 units) for direct replacement in existing systems where component-level compatibility is required. However, transition to 5-146258-8 is recommended for new procurement cycles to ensure regulatory compliance and sustained supplier support.

Compliance Considerations: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring consistent export control and tariff treatment. The MSL rating of 1 (Unlimited) for both parts indicates no moisture sensitivity restrictions during storage or handling.
