Substitute Part Grouping Explanation

Substitution eligibility for the TNPW1206249KBETA is determined by the following critical parameters:

• Resistance value: 249 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package format: 1206 (3216 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Number of terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The TNPW1206249KBEEA meets all substitution criteria. While it features a higher power rating (0.52W versus 0.25W) and extended operating temperature range (-55°C to 175°C versus -55°C to 125°C), these represent performance enhancements that maintain full compatibility. The substitute part operates within the same electrical and mechanical specifications required for direct replacement.
