RT0805FRE07866KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07866KL is a 0805 (2012 Metric) thin film chip resistor manufactured by YAGEO with a resistance value of 866 kOhms and ±1% tolerance. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is currently in active production status and available in Tape & Reel packaging with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent resistance values, power ratings, package dimensions, and operating temperature ranges are maintained while offering improved tolerance specifications or enhanced automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE07866KL are qualified based on the following criteria:

• Identical Resistance Value: 866 kOhms
• Equal or Superior Tolerance: ±1% or better (±0.1%)
• Matching Power Rating: 0.125W (1/8W)
• Identical Package: 0805 (2012 Metric)
• Matching Composition: Thin Film
• Compatible Operating Temperature Range: -55°C to 155°C minimum
• Equivalent or Better Temperature Coefficient: ±50ppm/°C or lower
• Equivalent Compliance: ROHS3 Compliant, MSL 1

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the RT0805FRE07866KL while offering enhanced specifications:

ERA-6AEB8663V (Panasonic Electronic Components): This substitute provides improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C). The part carries AEC-Q200 automotive qualification and maintains identical package dimensions and operating temperature range. Inventory availability is 16,435 pieces.

RG2012P-8663-B-T5 (Susumu): This substitute also provides improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C). The part includes anti-sulfur protection and AEC-Q200 automotive qualification. The seated height is 0.020" (0.50mm), which is 0.004" lower than the main part. Inventory availability is 683 pieces.

Both substitutes are ROHS3 compliant with MSL 1 rating and maintain the same operating temperature range (-55°C to 155°C).

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB8663V or RG2012P-8663-B-T5 be used as direct replacements for RT0805FRE07866KL?

A: Yes. Both substitute parts maintain identical resistance value (866 kOhms), power rating (0.125W), package type (0805), and operating temperature range (-55°C to 155°C). The improved tolerance and temperature coefficient specifications of the substitutes are compatible with applications designed for the main part.

Q: What is the difference between the two substitute parts?

A: Both ERA-6AEB8663V and RG2012P-8663-B-T5 offer ±0.1% tolerance and ±25ppm/°C temperature coefficient. The primary differences are: RG2012P-8663-B-T5 includes anti-sulfur protection and has a maximum seated height of 0.020" (0.50mm) compared to 0.024" (0.60mm) for ERA-6AEB8663V. Manufacturer and inventory availability also differ.

Q: Are there any package dimension concerns when substituting?

A: Both substitute parts use the identical 0805 (2012 Metric) package with length 0.079" and width 0.049". The RG2012P-8663-B-T5 has a lower maximum seated height (0.020" versus 0.024"), which may be advantageous in space-constrained applications but does not prevent substitution.

Q: Do the substitute parts have automotive certifications?

A: Yes. Both ERA-6AEB8663V and RG2012P-8663-B-T5 carry AEC-Q200 automotive qualification. The main part RT0805FRE07866KL does not have this rating.

Q: What is the significance of the anti-sulfur feature in RG2012P-8663-B-T5?

A: Anti-sulfur protection is a feature that enhances reliability in environments with sulfur-containing compounds. This is provided only by the RG2012P-8663-B-T5 substitute and is not present in the main part or the ERA-6AEB8663V substitute.
