Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC2003F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 200 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±50ppm/°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 rating
• ROHS3 compliance
• Moisture Sensitivity Level 1

Substitute parts must match all electrical specifications, maintain identical package dimensions, and retain automotive-grade certification. Composition (thick film) and manufacturer series (RK73G) remain consistent across qualified substitutes.
