RC2010FK-072RL Equivalent & Substitute Parts

Part Overview

The RC2010FK-072RL is a 2 Ohm ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. Manufactured by YAGEO under the RC_L series, this component is actively produced and widely stocked. The part is ROHS3 compliant with moisture resistant construction and operates across the -55°C to 155°C temperature range. Substitute parts may be required due to supply constraints, design upgrades requiring automotive qualification, or application-specific compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2010FK-072RL is determined by strict equivalence across the following parameters:

• Resistance value: 2 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package designation: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture resistance: Required
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

The AC2010FK-072RL qualifies as a direct substitute based on identical electrical specifications and package dimensions. The primary distinction is the addition of AEC-Q200 automotive qualification in the substitute part, which represents an upgrade in reliability standards without altering core electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AC2010FK-072RL is the appropriate choice for automotive applications or designs requiring AEC-Q200 compliance. This part meets enhanced reliability and qualification standards while maintaining full electrical and mechanical compatibility with the RC2010FK-072RL.

Both parts carry ROHS3 compliance, unlimited moisture sensitivity rating, and identical thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-072RL be used as a direct replacement for RC2010FK-072RL?

A: Yes. The AC2010FK-072RL is electrically and mechanically identical to the RC2010FK-072RL. Both parts share the same 2 Ohm resistance, ±1% tolerance, 0.75W power rating, 2010 package dimensions, and operating temperature range. The AC variant includes AEC-Q200 automotive qualification, which does not affect compatibility.

Q: What is the significance of AEC-Q200 qualification on the AC2010FK-072RL?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. This certification does not alter the electrical or mechanical properties of the part; it indicates the manufacturer has met additional testing and quality requirements specific to automotive applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in the 2010 (5025 Metric) case with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and a maximum seated height of 0.026" (0.65mm). They are footprint-compatible on PCB layouts.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both RC2010FK-072RL and AC2010FK-072RL carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the temperature coefficient difference, if any?

A: There is no difference. Both parts have a temperature coefficient of ±200ppm/°C and operate across the identical -55°C to 155°C temperature range.
