TNPW0805301KBETA Equivalent & Substitute Parts

Part Overview

The TNPW0805301KBETA is a 301 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package format, rated at 0.125W (1/8W) power dissipation. 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 and available in tape and reel packaging. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805301KBETA is determined by the following critical parameters:

• Resistance value must be 301 kOhms
• Tolerance must be ±0.1%
• Package must be 0805 (2012 Metric)
• Composition must be thin film
• Temperature coefficient must be ±25ppm/°C
• Number of terminations must be 2
• Power rating must meet or exceed 0.125W

The TNPW0805301KBEEA qualifies as a direct substitute based on these criteria. While the substitute part offers enhanced power rating (0.26W), extended operating temperature range (-55°C ~ 175°C), and additional features (anti-sulfur, automotive AEC-Q200, moisture resistant), the core electrical and mechanical parameters remain compatible with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the TNPW0805301KBETA and TNPW0805301KBEEA are active production components from Vishay Dale with identical core electrical specifications. The TNPW0805301KBEEA offers compliance advantages through ROHS3 certification and REACH unaffected status, compared to the original part's RoHS non-compliant and REACH affected designation. The substitute part includes automotive AEC-Q200 qualification, anti-sulfur treatment, and moisture resistance features. The extended operating temperature range to 175°C and increased power dissipation capability (0.26W versus 0.125W) provide additional design margin without compromising the specified 301 kOhms ±0.1% resistance value or mechanical compatibility in 0805 package format.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805301KBEEA replace TNPW0805301KBETA in all applications?

A: Yes, within the electrical and mechanical parameters. Both parts maintain 301 kOhms ±0.1% resistance, ±25ppm/°C temperature coefficient, and identical 0805 package dimensions. The substitute part's higher power rating and extended temperature range do not create incompatibility.

Q: What are the key differences between these two parts?

A: The primary differences are power rating (0.26W versus 0.125W), maximum operating temperature (175°C versus 125°C), RoHS compliance status (ROHS3 versus non-compliant), and additional features in the substitute (anti-sulfur, AEC-Q200, moisture resistant).

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package with identical length (0.079"), width (0.049"), and maximum seated height (0.022").

Q: Does the substitute part maintain the same tolerance specification?

A: Yes. Both parts are specified at ±0.1% tolerance with ±25ppm/°C temperature coefficient.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard. The TNPW0805301KBEEA meets this automotive-grade reliability requirement, while the original TNPW0805301KBETA is military-grade. This does not affect substitution compatibility for standard applications.
