Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2704F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2.7 MOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.05W / 1/20W (exact match)
• Temperature coefficient: ±200ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package type: 0201 (0603 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) (exact match)
• Height seated maximum: 0.010" (0.26mm) (exact match)

Compliance & Certification Requirements:

• AEC-Q200 automotive qualification (required)
• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)

Substitute parts must satisfy all parameters listed above without exception. Parts meeting these criteria are functionally and mechanically interchangeable in circuit applications.
