Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-644803-5 is the direct functional equivalent of the obsolete 644803-5 connector header. Both parts share identical mechanical dimensions, electrical ratings, and performance characteristics within the MTA-100 series.

Product Status Consideration: The 644803-5 is classified as obsolete, while the 2-644803-5 maintains active product status. For new designs and ongoing production requirements, the 2-644803-5 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Regulatory Compliance: The 2-644803-5 achieves ROHS3 compliance, whereas the 644803-5 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements. Both parts maintain identical UL94 V-0 flammability ratings and equivalent electrical performance across the specified operating temperature range of -55°C to 105°C.

Contact Finish Specification: The primary technical difference between the parts is the contact finish composition. The 644803-5 features Tin-Lead plating on both mating and post contacts, while the 2-644803-5 uses Tin plating. Both finishes are compatible with standard solder termination processes and provide equivalent electrical performance for general-purpose applications.

Mechanical and Electrical Equivalence: All mechanical parameters including pitch spacing (0.100"), position count (5), mounting configuration (through-hole right-angle), shrouding (4-wall), and electrical ratings (250VAC, -55°C to 105°C) are identical between the two parts. Direct substitution is supported without design modification.
