TNPW08051K18BEEN Equivalent & Substitute Parts

Part Overview

The TNPW08051K18BEEN is a 1.18 kOhms ±0.1% 0.26W Chip Resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This thin film resistor features anti-sulfur coating, automotive AEC-Q200 qualification, and moisture resistance, making it suitable for demanding automotive and industrial applications. The part is currently active in production with 1008 units in stock. Substitute parts may be required due to supply constraints, lead time considerations, or specific application requirements within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Resistance value: 1.18 kOhms
• Tolerance: ±0.1%
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant

The substitute parts listed below meet these core electrical and mechanical specifications. Power rating variations are acceptable within the constraints of the 0805 package form factor and application requirements. Operating temperature range and specific certifications (such as AEC-Q200) may vary between substitutes and should be evaluated against application-specific demands.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB1181V (Panasonic Electronic Components) is a direct substitute for applications where the 0.125W power rating is sufficient. This part maintains AEC-Q200 automotive qualification, ROHS3 compliance, and identical electrical specifications. It is suitable for general automotive and industrial applications with standard thermal requirements.

RT0805BRD071K18L (YAGEO) provides equivalent electrical performance with 0.125W power rating and ROHS3 compliance. This part does not carry AEC-Q200 certification and should be selected only for non-automotive applications or where automotive qualification is not mandated.

RP73PF2A1K18BTDF (TE Connectivity Passive Product) offers 0.25W power rating, approaching the original specification. However, this part is RoHS non-compliant and does not carry AEC-Q200 certification. Selection of this part requires explicit compliance review and is not recommended for new automotive designs or applications with strict RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB1181V replace TNPW08051K18BEEN in all applications?

A: ERA-6AEB1181V is electrically and mechanically compatible with identical resistance, tolerance, temperature coefficient, and package specifications. The primary difference is reduced power rating (0.125W vs. 0.26W). Substitution is valid only if circuit power dissipation does not exceed 0.125W at the resistor location.

Q: What is the impact of operating temperature range differences?

A: TNPW08051K18BEEN operates to 175°C, while ERA-6AEB1181V and RT0805BRD071K18L operate to 155°C. Applications requiring operation above 155°C must use the original Vishay Dale part or confirm that substitute parts meet the thermal requirements of the specific circuit.

Q: Why is RP73PF2A1K18BTDF marked as RoHS non-compliant?

A: RP73PF2A1K18BTDF does not meet ROHS3 compliance standards. This part should be selected only for legacy systems, non-regulated applications, or where RoHS exemptions apply. New designs targeting automotive or consumer markets should use ROHS3-compliant alternatives.

Q: Are all substitute parts qualified to AEC-Q200?

A: ERA-6AEB1181V carries AEC-Q200 automotive qualification. RT0805BRD071K18L and RP73PF2A1K18BTDF do not specify AEC-Q200 certification. For automotive applications, ERA-6AEB1181V is the preferred substitute.

Q: Can package dimensions vary between these parts?

A: All parts use the 0805 (2012 Metric) package with identical length and width (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height variations are minimal (0.022" to 0.026" seated height) and do not affect PCB layout or assembly compatibility.
