Key Parameters

Substitute Part Grouping Explanation

Substitution of the TNPW0805330KBETA is determined by the following critical parameters:

• Resistance value: 330 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 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)
• Physical Dimensions: 0.079" L x 0.049" W, Height 0.022" max (exact match required)

The substitute part TNPW0805330KBEEA meets all critical electrical and mechanical parameters. Differences in power rating (0.26W vs. 0.125W), operating temperature upper limit (175°C vs. 125°C), and compliance certifications represent enhancements or expanded capabilities rather than deviations from core specifications.

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805330KBEEA serves as a direct functional substitute for the TNPW0805330KBETA. Both parts maintain identical resistance, tolerance, package geometry, and thermal characteristics. The substitute part offers enhanced compliance status (ROHS3 Compliant vs. RoHS non-compliant) and REACH Unaffected designation, making it suitable for applications with stricter environmental regulations.

The TNPW0805330KBEEA includes AEC-Q200 automotive qualification and anti-sulfur, moisture-resistant features. The increased power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C to 175°C vs. -55°C to 125°C) provide additional design margin without compromising electrical performance in applications designed for the original part.

Selection between these parts depends on compliance requirements and environmental operating conditions. Both parts are active in production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805330KBEEA replace TNPW0805330KBETA in existing designs?

A: Yes. Both parts share identical resistance (330 kOhms), tolerance (±0.1%), package (0805), composition (thin film), temperature coefficient (±25ppm/°C), and physical dimensions. Electrical and mechanical compatibility is confirmed.

Q: What are the key differences between these parts?

A: The substitute part TNPW0805330KBEEA features higher power rating (0.26W vs. 0.125W), extended operating temperature range (175°C vs. 125°C upper limit), ROHS3 compliance (vs. non-compliant), REACH Unaffected status (vs. REACH Affected), and automotive AEC-Q200 qualification with anti-sulfur and moisture-resistant properties.
