AC0201FR-07221RL Equivalent & Substitute Parts

Part Overview

The AC0201FR-07221RL is a 221 Ohm ±1% thick film chip resistor in 0201 package (0.60mm × 0.30mm) rated for 0.05W (1/20W) power dissipation. This component is manufactured by YAGEO under the AC series and is qualified to AEC-Q200 automotive standards with moisture resistance. The part is currently in active production status with 988 units in stock.

Substitute parts are necessary when the primary part experiences supply constraints, when alternative packaging formats are required for manufacturing processes, or when design requirements allow for functionally equivalent components from different manufacturers that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-07221RL is determined by strict equivalence across the following parameters:

• Resistance value: 221 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in operating temperature range, packaging format (Tape & Reel vs. Cut Tape), product status, and manufacturer-specific features do not disqualify substitution eligibility when the above parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are electrically and mechanically equivalent to the AC0201FR-07221RL across core parameters. Selection among these alternatives should be based on the following factors:

Product Status Consideration: The RK73H1HTTC2210F carries a "Not For New Designs" status. This part remains functionally equivalent but is not recommended for new product development. Existing designs currently using this part number may continue to source it for production continuity.

Active Production Parts: RC0201FR-07221RL, CRCW0201221RFNED, RMCF0201FT221R, and ERJ-1GNF2210C are all in active production status and are suitable for new designs.

Packaging Format: RC0201FR-07221RL is available in Cut Tape & Digi-Reel format, which may be preferred for certain assembly processes. All other substitutes are supplied in Tape & Reel format, matching the original part's packaging.

Operating Temperature Range: The AC0201FR-07221RL, CRCW0201221RFNED, and RK73H1HTTC2210F support -55°C to 155°C operation. RC0201FR-07221RL and ERJ-1GNF2210C support -55°C to 125°C. For applications requiring the full 155°C upper limit, select from the first group.

Compliance & Certifications: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating. The AC0201FR-07221RL and RK73H1HTTC2210F include AEC-Q200 automotive qualification; this feature is not specified for other substitutes but does not affect electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-07221RL be used as a direct replacement for AC0201FR-07221RL?

A: Yes. Both parts are YAGEO products with identical electrical specifications (221 Ω, ±1%, 0.05W, ±200ppm/°C). The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) and operating temperature range (-55°C to 125°C vs. -55°C to 155°C). If your application operates within -55°C to 125°C, this part is fully equivalent.

Q: Why is RK73H1HTTC2210F marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development of this product line. The part remains available and functionally equivalent, but new designs should select from active production alternatives. Existing production runs using this part may continue sourcing it.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. Only AC0201FR-07221RL and RK73H1HTTC2210F carry explicit AEC-Q200 automotive qualification. CRCW0201221RFNED, RMCF0201FT221R, and ERJ-1GNF2210C do not list this certification. If AEC-Q200 qualification is a design requirement, select from the first two parts.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel is a continuous reel format suitable for high-speed automated assembly. Cut Tape & Digi-Reel is pre-cut tape on a reel, often preferred for lower-volume production or mixed-component assembly. Both formats contain the same component; the difference is in handling and feeding during manufacturing.

Q: Can I use CRCW0201221RFNED if my circuit requires -55°C to 155°C operation?

A: Yes. CRCW0201221RFNED supports the full -55°C to 155°C operating range, matching the AC0201FR-07221RL specification.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
