AC2010JK-072RL Equivalent & Substitute Parts

Part Overview

The AC2010JK-072RL is a 2 Ohm ±5% 0.75W thick film chip resistor in 2010 (5025 Metric) package manufactured by YAGEO. This component is automotive-grade (AEC-Q200 certified), moisture resistant, and actively produced. Substitute parts are identified to provide design flexibility, inventory alternatives, and tolerance upgrades while maintaining electrical and mechanical compatibility within the 2010 package footprint.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

Resistance value: 2 Ohms (exact match required)
Package / Case: 2010 (5025 Metric) (exact match required)
Power rating: 0.75W minimum
Operating temperature range: -55°C ~ 155°C minimum
Composition: Thick Film
RoHS3 Compliant status

Tolerance Variations: Parts with ±1% tolerance (RC2010FK-072RL, AC2010FK-072RL) are direct upgrades to the ±5% specification and are electrically interchangeable.

Automotive Certification: Parts with AEC-Q200 rating (RK73B2HTTE2R0J, CRCW20102R00JNEF, AC2010FK-072RL) meet automotive-grade requirements. Parts without explicit AEC-Q200 designation (RC2010FK-072RL, RC2010JK-072RL) are suitable for non-automotive applications or where automotive certification is not mandated.

Manufacturer Diversity: Substitute parts from YAGEO (RC series), KOA Speer Electronics (RK73B series), and Vishay Dale (CRCW series) provide supply chain alternatives while maintaining identical electrical performance and package compatibility.

Engineering Selection Recommendations

For Automotive Applications (AEC-Q200 Required): AC2010FK-072RL is the preferred upgrade option, combining AEC-Q200 certification, moisture resistance, and ±1% tolerance. RK73B2HTTE2R0J and CRCW20102R00JNEF provide AEC-Q200 certified alternatives with ±5% tolerance matching the original specification.

For Non-Automotive Applications: RC2010JK-072RL offers identical electrical specifications to the main part with higher inventory availability. RC2010FK-072RL provides a tolerance upgrade to ±1% for applications requiring tighter resistance control.

For Supply Chain Continuity: All substitute parts maintain ROHS3 compliance and identical operating temperature ranges. Selection should prioritize inventory availability and lead time requirements while maintaining the 2010 package specification.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072RL replace AC2010JK-072RL in automotive applications? A: RC2010FK-072RL is not AEC-Q200 certified. For automotive applications requiring AEC-Q200 compliance, use AC2010FK-072RL, RK73B2HTTE2R0J, or CRCW20102R00JNEF.

Q: What is the difference between ±5% and ±1% tolerance parts? A: Tolerance defines the maximum deviation from the nominal 2 Ohm resistance value. ±1% tolerance parts (RC2010FK-072RL, AC2010FK-072RL) provide tighter resistance control suitable for precision circuits. ±5% tolerance parts are acceptable for general-purpose applications.

Q: Are all substitute parts in the same 2010 package? A: Yes. All listed parts use the 2010 (5025 Metric) package with identical footprint dimensions (0.197" L x 0.098" W). Maximum seated height varies between 0.026" and 0.028", which is negligible for standard PCB assembly.

Q: Which substitute has the best inventory availability? A: RK73B2HTTE2R0J has the highest inventory at 9,423 pieces. RC2010JK-072RL offers 5,350 pieces with identical electrical specifications to the main part.

Q: Are moisture-resistant features required for all applications? A: Moisture resistance is specified for AC2010JK-072RL and RC2010FK-072RL. For applications in high-humidity or harsh environments, moisture-resistant variants are recommended. RK73B2HTTE2R0J and CRCW20102R00JNEF do not list explicit moisture resistance but maintain MSL 1 rating.
