Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 1-104549-1 and the equivalent part 6-104549-1 is based on strict electrical and mechanical parameter matching. Both parts share identical specifications across all critical dimensions and functional characteristics:

Key Parameters for Substitution Compatibility:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (12 positions, 2 rows)
• Mating pitch and row spacing (0.050" and 0.100" respectively)
• Mounting technology (Surface Mount)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Operating temperature range (-65°C ~ 105°C)
• Voltage rating (30VAC)
• Insulation material and flammability rating (PPA, UL94 V-0)
• Contact material and mating contact finish (Copper Alloy, Gold)

The parts differ only in post contact finish specification and RoHS compliance status, which do not affect mechanical or electrical interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both 1-104549-1 and 6-104549-1 are active products from TE Connectivity within the AMPMODU System 50 series and are electrically and mechanically interchangeable for standard applications. Selection between these parts should be based on the following criteria:

For applications requiring RoHS3 compliance: The 6-104549-1 substitute part is ROHS3 compliant and is the appropriate selection for regulated industries and markets with RoHS requirements.

For applications with legacy RoHS non-compliance specifications: The 1-104549-1 main part maintains RoHS non-compliant status and may be selected where existing design documentation specifies this requirement.

For inventory and lead time considerations: The 6-104549-1 substitute part currently maintains higher inventory levels (1062 units) compared to the main part (727 units), providing improved availability for procurement planning.

Post contact finish consideration: The 1-104549-1 features Tin-Lead post finish, while the 6-104549-1 features Tin post finish. Both finishes are compatible with standard solder reflow processes and do not affect mating performance.

Both parts operate across identical temperature ranges (-65°C ~ 105°C), voltage ratings (30VAC), and flammability standards (UL94 V-0), ensuring functional equivalence in automotive, general purpose, medical, and telecommunications applications.

Frequently Asked Questions (FAQ)
