AT0805FRE071K8L Equivalent & Substitute Parts

Part Overview

The AT0805FRE071K8L is a 1.8 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package format, rated for 0.125W (1/8W) power dissipation. This component features anti-sulfur coating, automotive AEC-Q200 qualification, and moisture resistance, making it suitable for automotive and harsh environment applications. The part is currently active in production with 876 pieces in stock.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements allow for alternative specifications within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT0805FRE071K8L is determined by the following critical parameters:

• Resistance Value: Must be 1.8 kOhms
• Package Format: Must be 0805 (2012 Metric)
• Power Rating: Must be 0.125W (1/8W) minimum
• Composition: Thin film construction
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C minimum
• Moisture Sensitivity: MSL 1 or better
• RoHS Compliance: ROHS3 Compliant

The substitute parts listed below meet all these criteria. Tolerance specifications may vary (±1% or ±0.1%), which represents an improvement in precision rather than a functional limitation. All substitutes are manufactured by YAGEO and maintain identical mechanical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active production components with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

AT0805FRE071K8L is the primary specification with automotive AEC-Q200 qualification and anti-sulfur coating, providing enhanced reliability in harsh automotive environments.

RT0805BRE071K8L offers superior tolerance specification (±0.1% versus ±1%), providing tighter resistance accuracy. This part is suitable for applications requiring higher precision while maintaining all other electrical and mechanical characteristics.

RT0805FRE071K8L matches the tolerance specification of the primary part (±1%) and provides the highest inventory availability (35,083 pieces), making it the preferred alternative for supply chain continuity.

Selection between substitute parts should be based on application precision requirements and inventory availability. All three parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRE071K8L replace AT0805FRE071K8L in automotive applications?

A: RT0805BRE071K8L meets all electrical and mechanical specifications. However, the primary part carries AEC-Q200 automotive qualification and anti-sulfur coating. Verify that your application requirements permit substitution without these specific certifications.

Q: What is the difference between ±1% and ±0.1% tolerance?

A: Tolerance defines the maximum deviation from the nominal resistance value. ±1% tolerance allows ±18 ohms deviation from 1.8 kOhms (1.782 kOhms to 1.818 kOhms). ±0.1% tolerance allows ±1.8 ohms deviation (1.7982 kOhms to 1.8018 kOhms). The ±0.1% specification provides higher precision for applications requiring tighter resistance accuracy.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use identical 0805 (2012 Metric) package format with two terminations, identical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm), and maximum seated height of 0.024" (0.60mm). They are directly interchangeable at the PCB level.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures. No baking or desiccant storage is required before soldering.

Q: Which substitute part should I select for supply chain optimization?

A: RT0805FRE071K8L provides the highest inventory availability (35,083 pieces) with matching tolerance specification (±1%), making it the optimal choice for supply chain continuity and cost efficiency.
