TNPW0805300KBEEA Equivalent & Substitute Parts

Part Overview

The TNPW0805300KBEEA is a 300 kOhms ±0.1% thin film chip resistor manufactured by Vishay Dale in 0805 (2012 Metric) package format. This component is rated for 0.26W power dissipation and is designed for automotive applications with AEC-Q200 qualification, anti-sulfur coating, and moisture resistance. The part is currently active in production with 5712 units in stock. Substitute parts are necessary when primary inventory is unavailable, when alternative manufacturers are preferred for supply chain diversification, or when application requirements permit lower power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805300KBEEA is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 300 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Automotive Rating: AEC-Q200 (required for automotive applications)
• RoHS Compliance: ROHS3 Compliant (required for regulatory compliance)

Secondary Consideration:

• Power Rating: The main part is rated at 0.26W. Substitute parts rated at 0.125W (1/8W) are acceptable when circuit design margins permit operation at lower power dissipation levels within the same package footprint.

All three substitute parts meet the primary matching criteria. The power rating difference reflects design trade-offs between thermal performance and component size within the standardized 0805 package.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB304V (Panasonic Electronic Components): This substitute maintains full AEC-Q200 automotive qualification and ROHS3 compliance. It is suitable for applications where the 0.125W power rating is sufficient and the maximum operating temperature of 155°C meets circuit requirements. Panasonic inventory availability is highest among substitutes at 81698 units.

RG2012P-304-B-T5 (Susumi): This substitute includes anti-sulfur coating matching the main part specification and maintains AEC-Q200 automotive qualification. The 0.020" seated height is the lowest among all options, which may provide advantages in space-constrained designs. Inventory availability is 42746 units.

RT0805BRD07300KL (YAGEO): This substitute meets all electrical and package specifications with ROHS3 compliance. However, automotive AEC-Q200 rating is not specified for this part number. Selection of this substitute should be limited to non-automotive applications or applications where automotive qualification is not a requirement. Inventory availability is 2657 units.

Frequently Asked Questions (FAQ)

Q: Can I use a 0.125W rated substitute in place of the 0.26W rated main part?

A: Substitution is permissible only when circuit analysis confirms that actual power dissipation in the resistor will remain below 0.125W under all operating conditions, including worst-case scenarios. The 0805 package physical dimensions are identical; the power rating difference reflects thermal performance capability. If circuit design requires sustained power dissipation above 0.125W, the main part TNPW0805300KBEEA must be used.

Q: Are all substitutes suitable for automotive applications?

A: ERA-6AEB304V and RG2012P-304-B-T5 both carry AEC-Q200 automotive qualification. RT0805BRD07300KL does not specify automotive qualification and should not be used in automotive applications unless explicitly approved by design engineering and quality assurance.

Q: What is the significance of the operating temperature range difference?

A: The main part operates to 175°C maximum, while all substitutes are rated to 155°C maximum. If the application requires operation above 155°C, only the TNPW0805300KBEEA main part is suitable. For applications with maximum operating temperatures at or below 155°C, all substitutes are acceptable.

Q: Does the height difference between parts affect PCB layout?

A: All parts are within 0.004" (0.10mm) of each other in seated height. This variation is negligible for standard PCB assembly processes and does not require layout modification. Height specifications are: TNPW0805300KBEEA 0.022" (0.55mm), RG2012P-304-B-T5 0.020" (0.50mm), ERA-6AEB304V and RT0805BRD07300KL both 0.024" (0.60mm).

Q: Are all parts RoHS compliant?

A: Yes, all parts including the main part and all three substitutes are ROHS3 compliant and REACH unaffected.
