AC0201FR-0743R2L Equivalent & Substitute Parts

Part Overview

The AC0201FR-0743R2L is a 43.2 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 features automotive AEC-Q200 qualification and moisture resistance, suitable for high-reliability applications across -55°C to 155°C operating range. The part is currently active in production with 1019 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward different feature sets, or when supply chain optimization requires sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 43.2 Ohms
• Tolerance: ±1%
• Power rating: 0.05W minimum
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Moisture sensitivity: MSL 1 or better
• RoHS compliance: ROHS3 Compliant

All substitute parts listed meet these core electrical and mechanical requirements. Differences in operating temperature range, product status, and specific feature certifications are noted in the parameter comparison table to enable informed selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring full automotive AEC-Q200 qualification across the extended temperature range (-55°C to 155°C), the AC0201FR-0743R2L and RK73H1HTTC43R2F are direct equivalents. The RK73H1HTTC43R2F carries "Not For New Designs" status, making AC0201FR-0743R2L the preferred primary choice for new development.

For applications where AEC-Q200 certification is not required and the operating temperature does not exceed 125°C, RC0201FR-0743R2L (YAGEO), ERJ-1GNF43R2C (Panasonic), and CRCW020143R2FNED (Vishay Dale) are suitable alternatives. All listed parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating.

RMCF0201FT43R2 (Stackpole Electronics) provides the widest inventory availability (20845 units) while maintaining AEC-Q200 rating and full -55°C to 155°C operating range, making it a strong secondary source for high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0743R2L replace AC0201FR-0743R2L in automotive applications?

A: RC0201FR-0743R2L is electrically equivalent but operates only to 125°C versus 155°C for the AC0201FR-0743R2L. It lacks AEC-Q200 certification. Use only if your application operates within -55°C to 125°C and does not require automotive qualification.

Q: What is the difference between parts with and without AEC-Q200 rating?

A: AEC-Q200 certification indicates the part meets automotive industry reliability standards for temperature cycling, moisture resistance, and failure rate testing. Use AEC-Q200 rated parts (AC0201FR-0743R2L, RK73H1HTTC43R2F, RMCF0201FT43R2) for automotive and high-reliability applications.

Q: Are all substitute parts in the same 0201 package?

A: Yes. All listed parts use the 0201 (0603 Metric) package with identical dimensions (0.024" L × 0.012" W, 0.60mm × 0.30mm) and maximum seated height of 0.010" to 0.011", ensuring PCB footprint compatibility.

Q: Why is RK73H1HTTC43R2F marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part number. While existing inventory is available and the part remains functionally equivalent, new designs should specify AC0201FR-0743R2L or RMCF0201FT43R2 for long-term supply assurance.

Q: Do all parts meet RoHS3 compliance?

A: Yes. All listed parts carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.
