Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW1206330KBETA is determined by the following critical parameters:

• Resistance Value: Must be 330 kOhms
• Tolerance: Must be ±0.1%
• Package / Case: Must be 1206 (3216 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Number of Terminations: Must be 2
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The TNPW1206330KBEEA meets all substitution criteria. While it features a higher power rating (0.52W versus 0.25W), an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), and additional certifications (AEC-Q200, anti-sulfur, moisture resistant), these represent enhancements that do not compromise compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The TNPW1206330KBEEA is a direct substitute for the TNPW1206330KBETA. Both parts are manufactured by Vishay Dale and maintain identical electrical and mechanical specifications for resistance, tolerance, package dimensions, and thermal characteristics.

The TNPW1206330KBEEA offers additional advantages: it is RoHS3 compliant (versus RoHS non-compliant for the original part), carries AEC-Q200 automotive qualification, includes anti-sulfur and moisture-resistant features, and supports an extended operating temperature range to 175°C. These enhancements make it suitable for automotive and harsh environment applications while remaining fully compatible with designs specified for the TNPW1206330KBETA.

Selection between these parts should be based on application requirements for compliance certifications, environmental performance, and temperature operating range. Both parts are currently in active production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the TNPW1206330KBEEA replace the TNPW1206330KBETA in existing designs?

A: Yes. Both parts share identical resistance value (330 kOhms), tolerance (±0.1%), package (1206), composition (thin film), temperature coefficient (±25ppm/°C), and physical dimensions. The TNPW1206330KBEEA is a direct substitute with enhanced specifications.

Q: What is the difference in power rating between these parts?

A: The TNPW1206330KBETA is rated at 0.25W, while the TNPW1206330KBEEA is rated at 0.52W. The higher power rating of the substitute part does not affect compatibility; it indicates greater thermal dissipation capability.

Q: Are there compliance differences between these parts?

A: Yes. The TNPW1206330KBEEA is RoHS3 compliant and carries AEC-Q200 automotive qualification. The TNPW1206330KBETA is RoHS non-compliant. Applications requiring automotive or RoHS compliance should use the TNPW1206330KBEEA.

Q: Do these parts have the same operating temperature range?

A: No. The TNPW1206330KBETA operates from -55°C to 125°C, while the TNPW1206330KBEEA operates from -55°C to 175°C. Applications requiring operation above 125°C must use the TNPW1206330KBEEA.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 1206 (3216 Metric) package with identical length (0.126"), width (0.063"), and maximum seated height (0.026"). They are mechanically interchangeable on PCBs.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
