AC0201FR-072K05L Equivalent & Substitute Parts

Part Overview

The AC0201FR-072K05L is a 2.05 kOhms ±1% thick film chip resistor in 0201 package (0.60mm x 0.30mm) rated at 0.05W (1/20W) power dissipation. This YAGEO component features automotive AEC-Q200 qualification and moisture resistance, designed for high-reliability applications operating across -55°C to 155°C. The part is currently in active production status with 698 units in stock. Equivalent and substitute parts are necessary to address supply chain flexibility, inventory optimization, and design continuity across multiple manufacturers while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-072K05L is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.05 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• RoHS3 compliance
• MSL 1 rating

All listed substitute parts meet these core electrical and mechanical requirements. Differences in operating temperature range, automotive ratings, and product status are noted but do not disqualify substitution for applications within the overlapping temperature specification (-55°C to 125°C minimum across all parts).

Parameter Comparison

Engineering Selection Recommendations

For new designs and active production, RC0201FR-072K05L (YAGEO), CRCW02012K05FNED (Vishay Dale), RMCF0201FT2K05 (Stackpole Electronics), and ERJ-1GNF2051C (Panasonic) are all suitable substitutes, as they maintain active product status and full RoHS3 compliance.

For applications requiring automotive AEC-Q200 qualification and extended temperature operation to 155°C, RMCF0201FT2K05 is the preferred substitute, offering the highest inventory availability (32,452 units) while maintaining AEC-Q200 rating and full operating temperature range.

RK73H1HTTC2051F, though AEC-Q200 qualified and temperature-rated to 155°C, carries "Not For New Designs" status and should be reserved for legacy system maintenance or existing design continuity only.

RC0201FR-072K05L and ERJ-1GNF2051C are suitable for applications with maximum operating temperature limited to 125°C.

Frequently Asked Questions (FAQ)

Q: Can I substitute AC0201FR-072K05L with RC0201FR-072K05L in my design?

A: Yes, both parts are electrically and mechanically identical (2.05 kΩ ±1%, 0.05W, 0201 package, ±200ppm/°C). The primary difference is operating temperature range: AC0201FR-072K05L operates to 155°C while RC0201FR-072K05L operates to 125°C. Substitution is valid if your application does not exceed 125°C.

Q: Which substitute offers the best supply availability?

A: ERJ-1GNF2051C (Panasonic) has the highest inventory at 71,937 units. RMCF0201FT2K05 (Stackpole) offers 32,452 units with AEC-Q200 qualification and full 155°C temperature range.

Q: Does the AC0201FR-072K05L require AEC-Q200 qualification in all applications?

A: No. AEC-Q200 is a feature of the AC0201FR-072K05L and RK73H1HTTC2051F. Other substitutes (RC0201FR-072K05L, CRCW02012K05FNED, ERJ-1GNF2051C, RMCF0201FT2K05) do not carry this rating but meet all other electrical and mechanical specifications. Use AEC-Q200 qualified parts only if your application or customer specification explicitly requires automotive qualification.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use RK73H1HTTC2051F as a direct replacement?

A: RK73H1HTTC2051F is electrically and mechanically equivalent but is marked "Not For New Designs." It is suitable only for replacement in existing systems or legacy designs. For new designs, select from active-status alternatives: RC0201FR-072K05L, CRCW02012K05FNED, RMCF0201FT2K05, or ERJ-1GNF2051C.

Q: What is the physical package size for all these parts?

A: All parts use the 0201 package (0603 Metric), measuring 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" to 0.011" (0.26mm to 0.28mm).
