Substitute Part Grouping Explanation

Substitution for the ERA-2HEC1202P is determined by the following critical parameters:

• Resistance value: 12 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• 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 (minimum requirement)

The ERA-2AEC1202X meets all substitution criteria. This part maintains identical electrical specifications and physical dimensions while offering enhanced product status and extended operating temperature range.
