AC0201FR-0724RL 24 Ohm 0201 Chip Resistor Equivalent & Substitute Parts

Part Overview

The AC0201FR-0724RL is a 24 Ohm ±1% thick film chip resistor in 0201 package (0.60mm × 0.30mm) rated for 0.05W power dissipation. Manufactured by YAGEO under the AC series, this component meets AEC-Q200 automotive qualification and includes moisture-resistant construction. The part is currently active in production with 737 units in stock.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit equivalent alternatives from other manufacturers that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-0724RL is determined by strict equivalence across the following parameters:

Electrical Parameters: Resistance value (24 Ohms), tolerance (±1%), power rating (0.05W), temperature coefficient (±200ppm/°C), and composition (thick film).

Mechanical Parameters: Package type (0201), physical dimensions (0.024" L × 0.012" W), height (0.010" max), and termination count (2).

Environmental & Compliance: RoHS3 compliance, MSL rating (1), operating temperature range (-55°C to 155°C minimum), and REACH status.

All identified substitute parts maintain these core parameters. Variations in product status, packaging format (tape & reel vs. cut tape), and optional automotive certifications do not affect functional interchangeability in applications where the base electrical and mechanical specifications are met.

Engineering Selection Recommendations

RC0201FR-0724RL (YAGEO): Active product status with high inventory availability (107,975 units). Electrically equivalent with identical tolerance and temperature coefficient. Operating temperature range of -55°C to 125°C is suitable for most applications within the AC0201FR-0724RL's specified range. ROHS3 compliant with MSL 1 rating.

CRCW020124R0FNED (Vishay Dale): Active product with 15,678 units in stock. Maintains full electrical and mechanical equivalence including the extended operating temperature range (-55°C to 155°C). ROHS3 compliant. Represents a direct cross-manufacturer alternative.

ERJ-1GNF24R0C (Panasonic Electronic Components): Active product with highest inventory (291,549 units). Electrically equivalent with identical specifications. Operating temperature range -55°C to 125°C. ROHS3 compliant with MSL 1 rating. Suitable for applications not requiring the extended upper temperature limit of 155°C.

ERJ-1GEF24R0C (Panasonic Electronic Components): Obsolete product status with 9,954 units remaining in stock. While electrically and mechanically equivalent, obsolescence status makes this unsuitable for new designs or long-term production requirements.

RK73H1HTTC24R0F (KOA Speer Electronics): Marked "Not For New Designs" with 40,027 units available. Maintains AEC-Q200 automotive qualification and extended temperature range (-55°C to 155°C). Suitable only for legacy design support or existing production continuity where automotive certification is required.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0724RL replace AC0201FR-0724RL in all applications?

A: RC0201FR-0724RL is electrically and mechanically equivalent. The operating temperature range difference (-55°C to 125°C vs. -55°C to 155°C) is the only specification variance. For applications operating within -55°C to 125°C, direct substitution is valid. Applications requiring operation above 125°C require the AC0201FR-0724RL or CRCW020124R0FNED.

Q: What is the difference between tape & reel and cut tape packaging?

A: Tape & reel (TR) packaging is supplied on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut tape (CT) is supplied in shorter tape segments. Both formats contain identical components; packaging format selection depends on assembly equipment and production volume requirements.

Q: Why is ERJ-1GEF24R0C listed as obsolete?

A: Panasonic has discontinued the ERJ-1GE series. While stock remains available, new designs should not incorporate obsolete parts due to future supply unavailability. ERJ-1GNF24R0C is the active Panasonic equivalent.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. Only AC0201FR-0724RL, RK73H1HTTC24R0F, and CRCW020124R0FNED carry AEC-Q200 automotive qualification. For automotive applications requiring this certification, select from these three options.

Q: Can I use RK73H1HTTC24R0F for new production?

A: RK73H1HTTC24R0F is marked "Not For New Designs." This part is available for legacy design support only. For new production, select from active-status alternatives: RC0201FR-0724RL, CRCW020124R0FNED, or ERJ-1GNF24R0C.

Q: Do all parts meet the same tolerance specification?

A: Yes. All listed parts maintain ±1% tolerance, ±200ppm/°C temperature coefficient, and 0.05W power rating. Tolerance and temperature stability are identical across all substitutes.
