Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC2002X is determined by the following critical parameters:

• Resistance value: 20 kOhms (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)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

The ERA-2AEC2002X meets all substitution criteria. It maintains identical electrical specifications and physical dimensions while offering extended operating temperature range (-55°C ~ 155°C) and automotive-grade AEC-Q200 qualification.

Parameter Comparison
