Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1202F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 12 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height - Seated (Max): 0.010" (0.26mm)
• Number of terminations: 2

Compliance & Certification:

• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Moisture Sensitivity Level 1

Substitute parts must match all electrical specifications, maintain identical package geometry and termination configuration, and retain automotive qualification status. The primary distinction between the main part and its substitute relates to product lifecycle status rather than functional or physical characteristics.

Parameter Comparison
