AC0201FR-0720RL Equivalent & Substitute Parts

Part Overview

The AC0201FR-0720RL is a 20 Ohm ±1% thick film chip resistor in 0201 package (0.60mm × 0.30mm) rated for 0.05W power dissipation. This automotive-grade component features AEC-Q200 qualification and moisture resistance, designed for high-reliability applications requiring compact form factors. The part is currently active in production with substantial inventory availability. Substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements across equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (20 Ohms), tolerance (±1%), power rating (0.05W), and temperature coefficient (±200ppm/°C)
Package Compatibility: 0201 form factor (0.60mm × 0.30mm) with identical termination count (2)
Environmental Compliance: RoHS3 compliance, MSL 1 rating, and REACH unaffected status
Composition: Thick film construction

All identified substitute parts meet these core requirements. Variations in operating temperature range, product status, and automotive certifications are noted but do not preclude functional substitution where application requirements permit.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Temperature Range)

RC0201FR-0720RL (YAGEO) and CRCW020120R0FNED (Vishay Dale) are direct functional equivalents with active product status. RC0201FR-0720RL operates to 125°C maximum, suitable for applications not requiring the full 155°C upper limit. CRCW020120R0FNED maintains the -55°C to 155°C range and offers the highest inventory availability among Vishay Dale offerings.

Automotive-Grade Alternative

RMCF0201FT20R0 (Stackpole Electronics) provides AEC-Q200 qualification with active status and full temperature range (-55°C to 155°C), making it suitable for automotive applications requiring equivalent reliability to the main part.

Legacy Consideration

RK73H1HTTC20R0F (KOA Speer Electronics) carries AEC-Q200 qualification and full temperature range but is marked "Not For New Designs." This part remains available for legacy system support or repair applications where existing qualification data is required.

High-Volume Alternative

ERJ-1GNF20R0C (Panasonic Electronic Components) offers the largest inventory position (878,972 units) with active status. Operating temperature is limited to 125°C; selection depends on application thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC0201FR-0720RL for AC0201FR-0720RL in automotive applications?

A: RC0201FR-0720RL is electrically equivalent but lacks AEC-Q200 certification. Substitution is valid only for non-automotive applications or where automotive qualification is not a design requirement. For automotive designs, use RMCF0201FT20R0 or RK73H1HTTC20R0F.

Q: What is the difference between the operating temperature ranges?

A: AC0201FR-0720RL, CRCW020120R0FNED, RK73H1HTTC20R0F, and RMCF0201FT20R0 operate to 155°C. RC0201FR-0720RL and ERJ-1GNF20R0C are rated to 125°C maximum. Selection depends on circuit thermal environment and design margin requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 rating and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Why is RK73H1HTTC20R0F marked "Not For New Designs"?

A: This designation indicates the manufacturer is transitioning the product line. While functionally equivalent and available in inventory, new designs should prioritize active-status alternatives such as RMCF0201FT20R0 or RC0201FR-0720RL to ensure long-term supply continuity.

Q: Can I use ERJ-1GNF20R0C as a direct replacement?

A: ERJ-1GNF20R0C is electrically and mechanically equivalent with active status and exceptional inventory availability. The 125°C maximum operating temperature is the only constraint; verify application thermal requirements before selection.

Q: Are all parts in 0201 package identical in physical dimensions?

A: All parts conform to 0201 (0603 Metric) package specification: 0.024" L × 0.012" W (0.60mm × 0.30mm). Height variation is minimal (0.010" to 0.011" seated maximum), with no functional impact on PCB assembly or circuit performance.
