Substitute Part Grouping Explanation

Substitution of the TSM-105-02-L-DH is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part TSM-105-02-L-DH-A maintains identical specifications in the following key areas:

  • Connector type, contact type, and gender (Header, Male Pin)
  • Pitch and position configuration (0.100" / 2.54mm, 10 positions, 2 rows)
  • Mounting orientation and termination method (Surface Mount Right Angle, Solder)
  • Contact geometry and materials (Square shape, Phosphor Bronze, Gold mating finish)
  • Insulation material and thermal rating (LCP, -55°C ~ 125°C)
  • Compliance certifications (ROHS3, UL94 V-0, MSL 1)

The only documented difference is the addition of a Board Guide feature in the substitute part. This feature does not alter electrical performance or mechanical compatibility with mating connectors, as it functions as a mechanical alignment aid during assembly.
