Substitute Part Grouping Explanation

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

Resistance value: 2.21 kOhms
Tolerance: ±1%
Power rating: 0.05W (1/20W)
Package: 0201 (0603 Metric)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C

Engineering Selection Recommendations

Primary Substitutes (Active Status):

AC0201FR-072K21L (YAGEO) and ERJ-1GNF2211C (Panasonic) are preferred substitutes. Both are active products with high inventory availability. AC0201FR-072K21L offers extended operating temperature range (-55°C ~ 155°C) and moisture-resistant features. ERJ-1GNF2211C provides the highest inventory stock (59737 units) and maintains identical electrical specifications.

Secondary Substitute (Active Status):

CRCW02012K21FNED (Vishay Dale) is an active alternative with extended temperature range and substantial inventory (13303 units). This part maintains full electrical and mechanical equivalence.

Avoid for New Designs:

ERJ-1GEF2211C (Panasonic) carries obsolete product status and should not be selected for new designs despite current inventory availability (1288 units).

Frequently Asked Questions (FAQ)

Q: Can AF0201FR-072K21L be directly replaced with AC0201FR-072K21L?

A: Yes. Both parts are YAGEO products with identical electrical specifications (2.21 kΩ, ±1%, 0.05W, 0201 package). AC0201FR-072K21L offers extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and moisture-resistant features, making it suitable for broader environmental conditions.

Q: What is the difference between ERJ-1GNF2211C and ERJ-1GEF2211C?

A: Both are Panasonic 2.21 kΩ ±1% 0201 resistors with identical electrical parameters. ERJ-1GNF2211C is active production with 59737 units in stock. ERJ-1GEF2211C is obsolete with limited inventory (1288 units). For new designs, select ERJ-1GNF2211C.

Q: Are all substitutes AEC-Q200 rated?

A: AF0201FR-072K21L and AC0201FR-072K21L carry explicit AEC-Q200 automotive qualification. CRCW02012K21FNED, ERJ-1GEF2211C, and ERJ-1GNF2211C do not list AEC-Q200 ratings in provided specifications. For automotive applications requiring AEC-Q200 compliance, use AF0201FR-072K21L or AC0201FR-072K21L.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All substitutes share identical 0201 package dimensions (0.60mm x 0.30mm) and footprint requirements. No PCB layout modifications are required for substitution.

Q: Which substitute offers the best supply availability?

A: ERJ-1GNF2211C (Panasonic) has the highest inventory at 59737 units, followed by AC0201FR-072K21L (YAGEO) at 16370 units and CRCW02012K21FNED (Vishay Dale) at 13303 units.

Q: What is the operating temperature difference between substitutes?

A: AF0201FR-072K21L and ERJ-1GNF2211C operate from -55°C to 125°C. AC0201FR-072K21L and CRCW02012K21FNED extend to -55°C to 155°C. Select extended-range parts for applications exceeding 125°C.
