Equivalent & Substitute Parts for AR0805FR-07105RL

Part Overview

The AR0805FR-07105RL is a 105 Ohm ±1% thick film chip resistor in 0805 (2012 Metric) package format, 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 with standard tolerance specifications.

Alternative equivalent parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific manufacturer certifications such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the AR0805FR-07105RL is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (105 Ohms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical
• Package Compatibility: 0805 (2012 Metric) package format with matching physical dimensions and termination count (2 terminations)
• Material Composition: Thick film construction with moisture-resistant properties
• Environmental Operating Range: -55°C to 155°C temperature range
• Regulatory Compliance: ROHS3 compliance and MSL Level 1 rating

All three substitute parts listed below meet these criteria without exception. Two substitutes (CRCW0805105RFKEA and ERJ-6ENF1050V) additionally carry AEC-Q200 automotive qualification, which represents an enhancement rather than a deviation from the base specification.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-07105RL (YAGEO) is the direct equivalent substitute within the same manufacturer's product line. This part maintains identical electrical and mechanical specifications with the AR0805FR-07105RL and carries the same active product status and compliance certifications. Selection of this part is appropriate for applications where YAGEO sourcing is preferred or when supply of the AR series is constrained.

CRCW0805105RFKEA (Vishay Dale) and ERJ-6ENF1050V (Panasonic) are functionally equivalent substitutes with the additional qualification of AEC-Q200 automotive-grade certification. These parts meet all base electrical and mechanical requirements and are suitable for applications requiring automotive-grade component reliability. The marginal height variation (0.020" for Vishay Dale versus 0.024" for the primary part) remains within typical PCB assembly tolerances and does not affect functional performance in standard 0805 footprints.

All three substitute parts carry active product status and full ROHS3 compliance with MSL Level 1 rating, ensuring long-term availability and environmental regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07105RL be used as a direct replacement for AR0805FR-07105RL?

A: Yes. Both parts are manufactured by YAGEO, share identical electrical specifications (105 Ohms ±1%, 0.125W), operate across the same temperature range (-55°C to 155°C), and use the same 0805 package format with matching physical dimensions. No circuit redesign or PCB layout modification is required.

Q: What is the difference between the YAGEO AR and RC series resistors?

A: Both series are thick film 0805 chip resistors with moisture-resistant properties and identical electrical performance. The AR and RC series represent different product lines within YAGEO's resistor portfolio. Selection between them is based on availability and supply chain requirements rather than technical performance.

Q: Why do CRCW0805105RFKEA and ERJ-6ENF1050V carry AEC-Q200 certification?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. These parts meet this additional qualification requirement, making them suitable for automotive and high-reliability applications. Non-automotive applications do not require this certification.

Q: Are there height differences between these substitute parts?

A: Minor height variations exist: AR0805FR-07105RL and RC0805FR-07105RL are 0.024" (0.60mm) maximum seated height, CRCW0805105RFKEA is 0.020" (0.50mm), and ERJ-6ENF1050V is 0.028" (0.70mm). These variations fall within standard PCB assembly tolerances for 0805 components and do not affect functionality in typical circuit applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All four parts use the same 0805 (2012 Metric) package footprint with identical lead spacing and termination configuration. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is MSL Level 1 and why does it matter?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life without moisture bake-out requirements. All four parts carry this rating, meaning they can be stored and handled under standard warehouse conditions without special moisture control procedures.
