TNPW0805220KBETA Equivalent & Substitute Parts

Part Overview

The TNPW0805220KBETA is a 220 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by Vishay Dale, this military-grade component operates across -55°C to 125°C with a temperature coefficient of ±25ppm/°C. The part is currently active in production with 749 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained while offering enhanced features, improved compliance status, or expanded operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805220KBETA is determined by the following criteria:

Resistance value and tolerance must remain 220 kOhms ±0.1% to ensure circuit performance specifications are met. Package type must be 0805 (2012 Metric) to maintain mechanical and thermal compatibility with PCB layouts. Temperature coefficient must be ±25ppm/°C to preserve frequency stability and thermal drift characteristics. Physical dimensions and termination count must match exactly for assembly compatibility.

Power rating may exceed the original 0.125W specification, as higher power-rated components in the same package are mechanically and electrically compatible. Operating temperature range may be extended beyond -55°C to 125°C without affecting substitutability. Composition must remain thin film to maintain tolerance and temperature coefficient performance.

The TNPW0805220KBEEA qualifies as a direct substitute based on these criteria: it maintains identical resistance, tolerance, package, temperature coefficient, and physical dimensions while offering increased power rating (0.26W) and extended operating temperature range (-55°C to 175°C).

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805220KBETA is an active product suitable for military applications. The TNPW0805220KBEEA substitute part maintains all critical electrical and mechanical specifications while providing additional benefits: ROHS3 compliance status, automotive AEC-Q200 qualification, anti-sulfur and moisture-resistant construction, and extended operating temperature range to 175°C. The substitute part is rated for higher power dissipation (0.26W versus 0.125W), making it suitable for applications requiring thermal margin or higher current environments. Both parts are manufactured by Vishay Dale and share identical base product number TNPW0805, confirming design compatibility.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805220KBEEA replace TNPW0805220KBETA in all applications?

A: Yes, the TNPW0805220KBEEA is electrically and mechanically compatible. It maintains identical resistance (220 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and package dimensions (0805). The higher power rating (0.26W) and extended temperature range (-55°C to 175°C) do not create incompatibility; they expand operational capability.

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

A: The TNPW0805220KBETA is rated at 0.125W (1/8W), while the TNPW0805220KBEEA is rated at 0.26W. Both parts occupy the same 0805 package. The higher power rating of the substitute indicates improved thermal performance and suitability for higher dissipation environments.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts designed for 0805 components.

Q: What compliance differences exist between these parts?

A: The TNPW0805220KBETA is RoHS non-compliant. The TNPW0805220KBEEA is ROHS3 compliant and carries AEC-Q200 automotive qualification. The substitute includes anti-sulfur and moisture-resistant features.

Q: Can the substitute part operate at higher temperatures?

A: Yes. The TNPW0805220KBEEA operates from -55°C to 175°C, compared to -55°C to 125°C for the original part. Both maintain the same ±25ppm/°C temperature coefficient across their respective ranges.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both TNPW0805220KBETA and TNPW0805220KBEEA are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
