AR0805FR-07124RL Equivalent & Substitute Parts

Part Overview

The AR0805FR-07124RL is a 124 Ohms ±1% thick film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by YAGEO under the AR series, this component is actively produced and widely used in general-purpose electronic applications requiring moisture-resistant film resistors. Alternative equivalent parts may be required due to supply chain availability, specific application certifications (such as automotive AEC-Q200 qualification), or enhanced power handling requirements in pulse-withstanding applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AR0805FR-07124RL is determined by the following mandatory parameters:

• Resistance Value: Must be 124 Ohms
• Tolerance: Must be ±1%
• Package: Must be 0805 (2012 Metric)
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±100ppm/°C
• Operating Temperature Range: Must be -55°C ~ 155°C
• Compliance: Must maintain ROHS3 and REACH compliance

Substitute parts are grouped into two categories based on power rating and application features:

Category A - Direct Equivalents (0.125W / 1/8W): Parts with identical power rating and general-purpose moisture-resistant construction.

Category B - Enhanced Specifications (0.5W / 1/2W with AEC-Q200): Parts with higher power dissipation capability and automotive qualification, suitable for applications requiring pulse-withstanding performance or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-07124RL (YAGEO) serves as a direct equivalent to the AR0805FR-07124RL with identical electrical specifications and moisture-resistant construction. Both are YAGEO products with active production status and ROHS3 compliance. Selection between AR and RC series depends on supply availability and inventory requirements.

CRCW0805124RFKEA (Vishay Dale) provides equivalent performance with automotive AEC-Q200 qualification. This part is suitable for applications requiring automotive-grade reliability while maintaining the original 0.125W power rating. Height specification is reduced to 0.020" (0.50mm) compared to the original 0.024" (0.60mm).

CRCW0805124RFKEAHP (Vishay Dale) and RCS0805124RFKEA (Vishay Dale) both offer enhanced 0.5W (1/2W) power rating with automotive AEC-Q200 qualification and pulse-withstanding capability. These parts are suitable for applications requiring higher transient power handling or pulse immunity. Both maintain 0.020" (0.50mm) maximum seated height.

ERJ-6ENF1240V (Panasonic Electronic Components) provides automotive AEC-Q200 qualification at the original 0.125W power rating. This part has a maximum seated height of 0.028" (0.70mm), which may require clearance verification in space-constrained layouts.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and identical operating temperature range (-55°C ~ 155°C).

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07124RL replace AR0805FR-07124RL in any application?

A: Yes. RC0805FR-07124RL is a direct equivalent with identical electrical and mechanical specifications. Both are YAGEO products with the same resistance, tolerance, power rating, package, and operating characteristics. Selection depends on supply chain availability.

Q: What is the difference between the 0.125W and 0.5W power-rated substitutes?

A: The 0.5W variants (CRCW0805124RFKEAHP and RCS0805124RFKEA) have four times the power dissipation capability. These are suitable for circuits with higher current or pulse conditions. The original AR0805FR-07124RL is rated at 0.125W; substitution with 0.5W parts is acceptable but not required unless the application demands higher power handling.

Q: Are automotive AEC-Q200 parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and stricter manufacturing controls. These parts exceed the requirements of general-purpose applications and are fully compatible with non-automotive designs.

Q: Does package height variation affect PCB assembly?

A: Package height differences exist among substitutes: AR0805FR-07124RL and RC0805FR-07124RL are 0.024" (0.60mm), Vishay Dale parts are 0.020" (0.50mm), and ERJ-6ENF1240V is 0.028" (0.70mm). Verify clearance requirements for your specific PCB layout, particularly in applications with height constraints or conformal coating processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH compliance status identical to the original AR0805FR-07124RL.

Q: Can I use ERJ-6ENF1240V if the original design specifies AR0805FR-07124RL?

A: Yes, provided your PCB layout accommodates the 0.028" (0.70mm) maximum seated height. ERJ-6ENF1240V is electrically and mechanically compatible with identical resistance, tolerance, power rating, and operating temperature range. Panasonic AEC-Q200 qualification provides equivalent or enhanced reliability.
