AC0201JR-072KL Equivalent & Substitute Parts

Part Overview

The AC0201JR-072KL is a 2 kOhms ±5% thick film chip resistor in 0201 package format, rated for 0.05W (1/20W) power dissipation. This component is manufactured by YAGEO and carries AEC-Q200 automotive qualification with moisture resistance. The part maintains active product status with 691 units currently in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements demand tighter tolerance specifications, or when alternative manufacturers' components offer improved lead times or inventory availability. The parts listed below maintain electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201JR-072KL is determined by the following criteria:

Mandatory Parameters (Must Match Exactly):

Resistance value: 2 kOhms
Package / Case: 0201 (0603 Metric)
Power rating: 0.05W (1/20W)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C to 155°C
RoHS compliance: ROHS3 Compliant
Moisture sensitivity level: MSL 1

Allowable Variation:

Tolerance: ±5% (primary specification) or ±1% (tighter tolerance acceptable for direct substitution)
Automotive rating: AEC-Q200 preferred; parts without this rating are not recommended for automotive applications
Product status: Active preferred; obsolete or "Not For New Designs" parts acceptable only for legacy system maintenance

Engineering Selection Recommendations

For Automotive Applications (AEC-Q200 Required): AC0201FR-072KL (YAGEO) is the primary upgrade option, offering tighter ±1% tolerance while maintaining full AEC-Q200 qualification and active product status. RK73B1HTTC202J (KOA Speer) provides equivalent electrical specifications with AEC-Q200 rating but carries "Not For New Designs" status, limiting its use to legacy system support or maintenance applications.

For Non-Automotive Applications: CRCW02012K00FNED (Vishay Dale) offers ±1% tolerance with superior inventory availability (43,003 units) and active product status. CRCW02012K00JNED (Vishay Dale) provides ±5% tolerance matching the original specification with active status and adequate stock levels.

Inventory Considerations: AC0201FR-072KL demonstrates the highest inventory availability among AEC-Q200 qualified parts (25,192 units), supporting rapid procurement for automotive designs. CRCW02012K00FNED offers the largest overall stock position (43,003 units) for non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can AC0201FR-072KL replace AC0201JR-072KL in automotive circuits? A: Yes. AC0201FR-072KL maintains identical electrical and mechanical specifications while offering tighter ±1% tolerance. Both parts carry AEC-Q200 qualification and operate across the same temperature range (-55°C to 155°C). The ±1% tolerance of the substitute provides improved accuracy without compromising compatibility.

Q: Why is RK73B1HTTC202J marked "Not For New Designs"? A: This designation indicates the part is in mature or declining production phase. While electrically and mechanically equivalent to AC0201JR-072KL with full AEC-Q200 qualification, it is restricted to legacy system maintenance and repair applications. New automotive designs should specify AC0201FR-072KL or equivalent active-status alternatives.

Q: Are Vishay Dale CRCW parts suitable for automotive applications? A: CRCW02012K00FNED and CRCW02012K00JNED lack AEC-Q200 automotive qualification. These parts are suitable for industrial, consumer, and non-safety-critical applications. Automotive designs requiring AEC-Q200 compliance must use YAGEO AC series or KOA Speer RK73B series parts.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity? A: MSL 1 rating indicates the component requires no special moisture control during storage, handling, or assembly. This eliminates bake-out requirements and simplifies supply chain logistics compared to higher MSL-rated components.

Q: Can I mix different manufacturers' parts in the same circuit board? A: Yes. All listed substitutes maintain identical electrical performance (2 kOhms, ±5% or ±1%, 0.05W) and mechanical compatibility (0201 package). Mixed-manufacturer designs are acceptable provided all parts meet the circuit's tolerance and temperature requirements.

Q: What packaging formats are available? A: AC0201JR-072KL, AC0201FR-072KL, RK73B1HTTC202J, and CRCW02012K00FNED are supplied in Tape & Reel (TR) format. CRCW02012K00JNED is available in Cut Tape (CT) and Digi-Reel® format. Tape & Reel packaging is standard for high-volume automated assembly.
