AC0201JR-0724RL Equivalent & Substitute Parts

Part Overview

The AC0201JR-0724RL is a 24 Ohm ±5% thick film chip resistor in 0201 package format, rated for 0.05W (1/20W) power dissipation. Manufactured by YAGEO under the AC series, this component is designed for automotive applications with AEC-Q200 qualification and moisture-resistant construction. The part maintains active product status with 671 units currently in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package format and performance envelope. Alternative sources become necessary due to supply chain considerations, inventory availability, or design requirement variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201JR-0724RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 24 Ohms (exact match required)
• Tolerance: ±5% or tighter (±1% acceptable as superior specification)
• Power rating: 0.05W minimum
• Package format: 0201 (0603 Metric) mandatory
• Composition: Thick film construction
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS and REACH compliance status

Two substitute parts meet these criteria with full electrical and mechanical compatibility:

RK73B1HTTC240J (KOA Speer Electronics) – Direct equivalent with identical specifications. Product status is Not For New Designs.

CRCW020124R0FNED (Vishay Dale) – Superior tolerance specification (±1% vs ±5%). Maintains all other parameters. Active product status.

Parameter Comparison

Engineering Selection Recommendations

AC0201JR-0724RL (Primary) – Recommended for new designs requiring AEC-Q200 automotive qualification. Active product status ensures long-term availability and supply chain stability. Suitable for applications where ±5% tolerance meets circuit requirements.

CRCW020124R0FNED (Preferred Alternative) – Recommended as primary substitute. Active product status with highest inventory availability (15,678 units). Superior ±1% tolerance provides tighter resistance specification, beneficial for precision applications. Maintains ROHS3 compliance and full temperature range compatibility. Absence of explicit AEC-Q200 marking does not preclude automotive use; Vishay Dale CRCW series components are widely qualified for automotive applications.

RK73B1HTTC240J (Secondary Alternative) – Electrically and mechanically equivalent with AEC-Q200 qualification. Not For New Designs status indicates potential discontinuation; use only when primary and preferred alternatives are unavailable. Suitable for legacy design maintenance or high-volume procurement scenarios where existing qualification data exists.

Frequently Asked Questions (FAQ)

Q: Can CRCW020124R0FNED replace AC0201JR-0724RL in automotive applications?

A: Yes. Both components share identical electrical specifications (24 Ohm, 0.05W, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and RoHS3 compliance. The CRCW020124R0FNED offers superior ±1% tolerance. Automotive qualification should be confirmed against your specific application requirements and design documentation.

Q: What is the difference between ±5% and ±1% tolerance?

A: Tolerance defines the maximum deviation from the nominal 24 Ohm value. ±5% allows 22.8–25.2 Ohm range; ±1% allows 23.76–24.24 Ohm range. The ±1% specification (CRCW020124R0FNED) provides tighter resistance control, beneficial for precision circuits. Both are functionally equivalent for applications tolerating ±5% variation.

Q: Are all three parts pin-compatible?

A: Yes. All three components use identical 0201 (0603 Metric) package format with two terminations. Footprint, solder pad geometry, and land pattern are identical. Direct PCB substitution is possible without layout modification.

Q: Why is RK73B1HTTC240J marked "Not For New Designs"?

A: This designation indicates the manufacturer is transitioning the product toward discontinuation. While currently available (7,340 units in stock), new designs should prioritize AC0201JR-0724RL or CRCW020124R0FNED for long-term supply assurance.

Q: Do all parts meet moisture sensitivity requirements?

A: Yes. All three components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. Standard PCB assembly processes and storage conditions are acceptable without special handling.

Q: Which part should I select for cost optimization?

A: Selection should prioritize product status and availability over unit cost. CRCW020124R0FNED offers highest inventory (15,678 units) and active status, reducing procurement risk. AC0201JR-0724RL provides automotive-specific qualification if required by application standards.
