Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC1602D is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

  • Resistance value: 16 kOhms
  • Tolerance: ±0.5%
  • Power rating: 0.05W (1/20W)
  • Temperature coefficient: ±200ppm/°C
  • Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

  • Package format: 0201 (0603 Metric)
  • Number of terminations: 2
  • Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
  • Maximum seated height: 0.010" (0.26mm)

Compliance & Certification:

  • Automotive AEC-Q200 qualification
