Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC4530X is determined by the following critical parameters:

• Resistance value: 453 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: Must support minimum -55°C to 125°C
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 or equivalent (required)

The ERA-2AEC4530X meets all substitution criteria. It maintains identical electrical specifications, package geometry, and composition while offering an extended operating temperature range (-55°C to 155°C) and automotive-grade AEC-Q200 qualification.
