YAGEO AA2010FK-072RL 2 Ohm 1% 3/4W 2010 Chip Resistor Equivalent & Substitute Parts

Part Overview

The YAGEO AA2010FK-072RL is a 2 Ohm ±1% 0.75W thick film chip resistor in 2010 (5025 Metric) package format. This component is designed for applications requiring anti-sulfur protection, automotive-grade reliability, and moisture resistance. The part is currently active in production and available in tape and reel packaging. Substitute parts are identified when the primary part experiences supply constraints, inventory limitations, or when alternative series options meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the AA2010FK-072RL are qualified based on the following critical parameters:

Electrical Specifications: Resistance value (2 Ohms), tolerance (±1%), and power rating (0.75W) must be identical
Package Compatibility: 2010 (5025 Metric) package format with matching physical dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm) and height (0.026" maximum seated height)
Environmental Performance: Temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1) must match
Compliance Standards: RoHS3 compliance and REACH unaffected status required
Composition: Thick film construction

The RC2010FK-072RL and AC2010FK-072RL meet all these criteria and are direct functional equivalents. Differences exist only in series designation and specific feature sets (anti-sulfur and automotive AEC-Q200 ratings vary by part).

Engineering Selection Recommendations

All three parts (AA2010FK-072RL, RC2010FK-072RL, and AC2010FK-072RL) are active production components from YAGEO with full RoHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

AA2010FK-072RL is the primary choice for applications requiring both anti-sulfur protection and automotive AEC-Q200 certification. This part combines enhanced environmental protection with automotive-grade reliability.

AC2010FK-072RL is suitable for automotive applications requiring AEC-Q200 certification without the anti-sulfur feature. This part maintains automotive-grade qualification while offering equivalent electrical and thermal performance.

RC2010FK-072RL is appropriate for general industrial and commercial applications where automotive certification is not required. This part provides standard moisture resistance with identical electrical specifications and thermal characteristics.

All three parts are electrically and mechanically interchangeable within the constraints of their respective feature sets and certifications.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072RL be used as a direct replacement for AA2010FK-072RL?

A: RC2010FK-072RL is electrically and mechanically compatible with AA2010FK-072RL. However, RC2010FK-072RL does not include anti-sulfur protection or AEC-Q200 automotive certification. Use RC2010FK-072RL only in applications where these features are not required.

Q: What is the difference between AA2010FK-072RL and AC2010FK-072RL?

A: Both parts carry AEC-Q200 automotive certification and moisture resistance. AA2010FK-072RL includes additional anti-sulfur protection. AC2010FK-072RL omits the anti-sulfur feature. All other electrical and mechanical parameters are identical.

Q: Are all three parts available in the same packaging format?

A: Yes. AA2010FK-072RL, RC2010FK-072RL, and AC2010FK-072RL are all supplied in Tape & Reel (TR) packaging with identical spool configurations.

Q: Do these parts have the same physical footprint?

A: Yes. All three parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.026" (0.65mm). They are PCB footprint compatible.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Are these parts RoHS compliant?

A: Yes. AA2010FK-072RL, RC2010FK-072RL, and AC2010FK-072RL are all ROHS3 compliant and REACH unaffected.
