Substitute Part Grouping Explanation

Substitution eligibility for the HV731JTTD3003F is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 300 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Specifications:

• Package format: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Environmental & Compliance:

• RoHS3 Compliance (required)
• Moisture Sensitivity Level 1 (required)
• High Voltage capability (required)

Substitute parts must satisfy all parameters listed above. Additional certifications or enhanced features do not disqualify a part from substitution eligibility.
