Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW080556K2BETA is determined by the following critical parameters:

• Resistance value: 56.2 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Number of Terminations: 2 (exact match required)

The substitute part TNPW080556K2BEEA meets all critical electrical and mechanical parameters. Variations in power rating (0.26W vs. 0.125W), operating temperature range (-55°C ~ 175°C vs. -55°C ~ 125°C), and compliance certifications (RoHS3 Compliant, AEC-Q200, Anti-Sulfur, Moisture Resistant) represent enhancements that do not compromise compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The TNPW080556K2BEEA serves as a direct substitute for the TNPW080556K2BETA based on matched electrical and mechanical specifications. The substitute part offers enhanced compliance status (ROHS3 Compliant vs. RoHS non-compliant) and automotive qualification (AEC-Q200). The increased power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 125°C) provide additional design margin without altering the core electrical performance. Both parts maintain identical resistance, tolerance, temperature coefficient, and physical dimensions, ensuring direct PCB compatibility and functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can TNPW080556K2BEEA replace TNPW080556K2BETA in existing designs?
