Substitute Part Grouping Explanation

Substitution of the obsolete 650281-1 connector is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5-650281-1 maintains identical specifications for position count, row configuration, pitch spacing, card thickness tolerance, contact material composition, contact finish specification, and operating temperature range. Both connectors are classified within the TE Connectivity AMP Connectors Linear series and employ identical press-fit termination methodology with through-hole mounting.

The primary distinction between the main part and its substitute is product status and regulatory compliance. The 650281-1 is obsolete and RoHS non-compliant, while the 5-650281-1 maintains active production status and achieves RoHS compliance. The substitute part carries the same base product number (650281) and represents the current production equivalent.

Substitution is valid when the following parameters are matched:

• 78 total positions across 2 rows
• 0.125" (3.18mm) pitch spacing
• Dual edge card edge configuration
• Card thickness range 0.054" ~ 0.072" (1.37mm ~ 1.82mm)
• Female gender
• Press-fit termination with through-hole mounting
• Copper alloy contacts with gold finish at 30.0µin thickness
• Operating temperature -65°C to 85°C
• PBT glass-filled insulation material
