AC0201FR-07105RL Equivalent & Substitute Parts

Part Overview

The AC0201FR-07105RL is a 105 Ohms ±1% thick film chip resistor in 0201 package (0.60mm x 0.30mm) rated for 0.05W power dissipation. This component is manufactured by YAGEO and meets automotive AEC-Q200 qualification with moisture resistance. The part maintains active product status and is suitable for high-reliability applications requiring compact form factors and automotive-grade performance.

Substitute parts become necessary when primary inventory is unavailable, when design flexibility permits alternative qualified sources, or when supply chain optimization requires cross-manufacturer sourcing while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-07105RL is determined by strict equivalence across the following critical parameters:

Resistance value and tolerance must match exactly (105 Ohms ±1%). Power rating must be identical or greater (0.05W minimum). Package and case dimensions must be 0201 (0603 Metric) to ensure PCB footprint compatibility. Composition type must be thick film. Temperature coefficient must be ±200ppm/°C or better. Operating temperature range must span -55°C to 155°C minimum. Automotive AEC-Q200 qualification is mandatory for equivalent substitution. RoHS3 compliance and MSL 1 rating must be maintained. All termination and dimensional specifications must align with the original part.

The RK73H1HTTC1050F from KOA Speer Electronics meets all these criteria and qualifies as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The AC0201FR-07105RL maintains active product status and is the primary selection for new designs. The RK73H1HTTC1050F is classified as "Not For New Designs" and should be reserved for legacy system support, field replacements, or applications where existing inventory must be utilized.

Both parts satisfy identical compliance requirements: AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. Selection between these parts should be driven by supply availability, inventory management objectives, and design phase requirements rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTC1050F be used as a direct replacement for AC0201FR-07105RL in new designs?

A: No. While RK73H1HTTC1050F is electrically and mechanically equivalent, its "Not For New Designs" status makes it unsuitable for new product development. Use AC0201FR-07105RL for new designs and reserve RK73H1HTTC1050F for legacy support or field replacements only.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are 0201 package (0603 Metric) with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints are interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both AC0201FR-07105RL and RK73H1HTTC1050F carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring high reliability.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. Both parts can be stored and handled without special moisture control procedures.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental and regulatory certifications.
