Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805300RBETA is determined by the following criteria:

Resistance value must equal 300 Ohms with tolerance of ±0.1%. Package must be 0805 (2012 Metric) with identical physical dimensions and two terminations. Composition must be thin film. Temperature coefficient must be ±25ppm/°C. Operating temperature range must encompass or exceed -55°C to 125°C. Power rating must be equal to or greater than 0.125W.

The TNPW0805300RBEEA meets all substitution criteria while providing enhanced features including anti-sulfur coating, automotive AEC-Q200 qualification, and moisture resistance. The extended operating temperature range to 175°C and increased power rating of 0.26W provide additional design margin.

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805300RBEEA is a direct substitute for the TNPW0805300RBETA in applications where the electrical specifications are identical. The substitute part maintains the same resistance value, tolerance, temperature coefficient, and package form factor while offering improved compliance status and extended operating temperature capability.

Selection between these parts depends on application requirements. The TNPW0805300RBETA remains appropriate for military applications requiring the specified composition and feature set. The TNPW0805300RBEEA is suitable for automotive and commercial applications requiring AEC-Q200 qualification, RoHS3 compliance, and extended temperature operation to 175°C.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805300RBEEA replace TNPW0805300RBETA in all applications?

A: Yes, the TNPW0805300RBEEA meets all electrical and mechanical substitution criteria. Both parts share identical resistance, tolerance, temperature coefficient, and package specifications. The substitute part provides equal or superior performance across all common parameters.

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

A: The TNPW0805300RBETA is rated at 0.125W (1/8W), while the TNPW0805300RBEEA is rated at 0.26W. The higher power rating of the substitute part provides additional thermal margin and does not affect electrical compatibility in circuits designed for the original part.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0805 (2012 Metric) with identical dimensions of 2.00mm length, 1.25mm width, and 0.55mm maximum seated height. They are mechanically interchangeable on PCBs designed for 0805 components.

Q: What compliance differences exist between these parts?

A: The TNPW0805300RBETA is RoHS non-compliant, while the TNPW0805300RBEEA is ROHS3 compliant. The substitute part is also REACH unaffected, whereas the original part is REACH affected. These differences are relevant for applications subject to environmental regulations.

Q: Does the extended temperature range of the substitute part affect compatibility?

A: No. The TNPW0805300RBEEA operates from -55°C to 175°C, which encompasses the original part's -55°C to 125°C range. The extended upper temperature limit provides additional design margin without affecting performance in applications limited to 125°C.
