Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805866KBEEA is determined by the following critical parameters:

• Resistance Value: Must be 866 kOhms
• Tolerance: Must be ±0.1%
• Package: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Automotive Compliance: Must carry AEC-Q200 certification
• RoHS Compliance: Must be ROHS3 Compliant
• Moisture Sensitivity: Must be MSL 1 or equivalent

The identified substitute parts meet all these criteria. Differences in power rating (0.26W vs. 0.125W) and maximum operating temperature (-55°C ~ 175°C vs. -55°C ~ 155°C) are noted but do not disqualify substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and AEC-Q200 automotive certification. Selection between the TNPW0805866KBEEA and its substitutes depends on application-specific power dissipation and temperature requirements.

The TNPW0805866KBEEA offers the highest power rating at 0.26W and the widest operating temperature range (-55°C ~ 175°C), making it suitable for high-power or high-temperature applications.

The ERA-6AEB8663V (Panasonic) and RG2012P-8663-B-T5 (Susumu) are rated for 0.125W power dissipation with an operating temperature range of -55°C ~ 155°C. These parts are suitable for applications where power dissipation does not exceed 0.125W and operating temperatures remain below 155°C. The RG2012P-8663-B-T5 includes anti-sulfur coating, matching the environmental protection of the primary part.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB8663V be used as a direct replacement for TNPW0805866KBEEA?

A: ERA-6AEB8663V is electrically compatible when application power dissipation does not exceed 0.125W and operating temperature remains below 155°C. Both parts share identical resistance, tolerance, temperature coefficient, package, and automotive certification. Physical dimensions are nearly identical with maximum height differences of 0.002" (0.05mm).

Q: What is the key difference between RG2012P-8663-B-T5 and TNPW0805866KBEEA?

A: The primary differences are power rating (0.125W vs. 0.26W) and maximum operating temperature (155°C vs. 175°C). Both parts are electrically identical in resistance, tolerance, and temperature coefficient. The RG2012P-8663-B-T5 has the lowest seated height at 0.020" (0.50mm) compared to 0.022" (0.55mm) for the primary part.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 certification and are rated for automotive use. The TNPW0805866KBEEA and RG2012P-8663-B-T5 include anti-sulfur coating for enhanced environmental protection.

Q: What is the impact of the 0.125W vs. 0.26W power rating difference?

A: The power rating determines the maximum continuous power dissipation the resistor can handle. Applications requiring power dissipation above 0.125W must use the TNPW0805866KBEEA. For applications below 0.125W, either part is acceptable.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
