Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TNPW08055K23BETA are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 5.23 kOhms
• Tolerance: ±0.1%
• Temperature coefficient: ±25ppm/°C
• Composition: Thin Film

Mechanical Parameters (Must Match):

• Package / Case: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Allowable Variations:

• Power rating may exceed the original specification (0.125W minimum)
• Operating temperature range may be extended beyond the original range
• Additional features (anti-sulfur, automotive certification, moisture resistance) are permissible
• RoHS and REACH compliance status may differ

The TNPW08055K23BEEA qualifies as a direct substitute based on matching all electrical and mechanical core parameters while offering enhanced power rating and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the TNPW08055K23BETA and TNPW08055K23BEEA are active production components from Vishay Dale with identical core electrical and mechanical specifications. Selection between these parts depends on application requirements:

TNPW08055K23BETA is appropriate for applications requiring military-grade specifications within the -55°C to 125°C operating range where RoHS non-compliance is acceptable.

TNPW08055K23BEEA is appropriate for applications requiring ROHS3 compliance, extended operating temperature to 175°C, automotive AEC-Q200 qualification, anti-sulfur properties, and moisture resistance. The higher power rating (0.26W versus 0.125W) provides additional thermal margin in the same package footprint.

Both parts maintain identical resistance value, tolerance, temperature coefficient, and physical dimensions, ensuring direct functional interchangeability in circuit designs where the specified parameters are the controlling factors.

Frequently Asked Questions (FAQ)

Q: Can TNPW08055K23BEEA replace TNPW08055K23BETA in existing designs?

A: Yes. Both parts share identical resistance (5.23 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and 0805 package dimensions. The TNPW08055K23BEEA offers higher power rating (0.26W) and extended temperature range (-55°C to 175°C), making it functionally compatible in all applications where the original part operates.

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

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

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCBs designed for 0805 resistors.

Q: Does the higher power rating of TNPW08055K23BEEA affect circuit performance?

A: No. Power rating is a maximum specification. The BEEA variant can safely operate at or below the power dissipation levels of the original BETA part. The higher rating provides additional thermal margin without affecting electrical performance.

Q: Which part should be selected for new designs?

A: Selection depends on compliance and environmental requirements. For applications requiring ROHS3 compliance, automotive qualification, or extended temperature operation, the TNPW08055K23BEEA is the appropriate choice. Both parts are active in production with adequate inventory availability.
