Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0603249KBETA is determined by the following critical parameters:

• Resistance Value: Must be 249 kOhms
• Tolerance: Must be ±0.1%
• Package Type: Must be 0603 (1608 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Number of Terminations: Must be 2

The TNPW0603249KBEEA meets all substitution criteria. While it features a higher power rating (0.21W versus 0.1W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), these represent performance enhancements rather than deviations. The higher power rating provides additional thermal margin, and the extended temperature range ensures compatibility in broader application environments. Both parts maintain identical resistance, tolerance, package geometry, and electrical characteristics essential for direct substitution.
