  • Power rating: 0.05W / 1/20W (exact match required)
  • Temperature coefficient: ±50ppm/°C (exact match required)
  • Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

  • Package / Case: 0201 (0603 Metric) (exact match required)
  • Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
  • Height - Seated (Max): 0.010" (0.26mm) (exact match required)

Compliance & Certification:

  • Automotive AEC-Q200 qualification (exact match required)
  • RoHS3 compliance (exact match required)
  • Moisture Sensitivity Level 1 (exact match required)

Composition:

  • Thick Film construction (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. The RK73G1HTTCM2403D meets all substitution criteria and is classified as an active product with manufacturer recommendation.
