Key Parameters

Substitute Part Grouping Explanation

Substitution of the 103777-6 is based on the following critical parameters that must remain consistent:

• Number of Positions: 12 positions (electrical compatibility requirement)
• Pitch - Mating: 0.100" (2.54mm) (mechanical compatibility requirement)
• Connector Category: Rectangular Connectors (form factor requirement)
• Manufacturer: TE Connectivity AMP Connectors (design lineage and quality assurance)

The primary substitute part, TE Connectivity AMP Connectors 5-146258-6, maintains these core parameters while offering an active product status with modern compliance certifications. This part belongs to the AMPMODU Mod II series, representing the current-generation equivalent within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The 5-146258-6 serves as the manufacturer-recommended substitute for the obsolete 103777-6. Selection of this substitute is justified by the following factors:

Product Status: The 5-146258-6 maintains active product status, ensuring long-term availability and continued manufacturing support. The 103777-6 is obsolete and subject to inventory depletion.

Compliance Certifications: The 5-146258-6 is ROHS3 compliant, meeting current regulatory requirements for electronic components in most jurisdictions. The 103777-6 is RoHS non-compliant, which may restrict its use in new designs or applications subject to RoHS regulations.

Electrical and Mechanical Compatibility: Both parts maintain 12 positions and 0.100" (2.54mm) pitch specifications, ensuring direct functional equivalence for board-to-board and cable interconnection applications.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) ratings, indicating identical moisture handling requirements.

Export Classification: Both parts share the same ECCN (EAR99) and HTSUS code classifications, maintaining consistent regulatory treatment.
