AF0201JR-072KL Equivalent & Substitute Parts

Part Overview

The AF0201JR-072KL is a 2 kOhms ±5% thick film chip resistor in 0201 package (0.60mm × 0.30mm) rated for 0.05W power dissipation. This YAGEO component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in harsh environments. The part is currently active in production with 1162 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when design requirements demand tighter tolerance specifications, or when alternative packaging formats are required for supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Parameters:

Resistance value: 2 kOhms (exact match required)
Package / Case: 0201 (0603 Metric) (exact match required)
Power rating: 0.05W minimum
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C minimum to 125°C minimum
RoHS3 compliance
MSL rating: 1 (Unlimited)

Tolerance Flexibility: Parts with ±1% tolerance are direct upgrades to the ±5% specification and are fully interchangeable in applications where the original tolerance is acceptable. Parts with ±5% tolerance maintain exact specification compliance.

Packaging Format Variations: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging formats are functionally equivalent; selection depends on assembly process requirements and supply chain logistics.

Engineering Selection Recommendations

Direct Equivalents (Specification Match): ERJ-1GNJ202C and CRCW02012K00JNED maintain identical electrical specifications to AF0201JR-072KL with 2 kOhms ±5% resistance and -55°C to 125°C operating range. Both are active production parts with substantial inventory availability. ERJ-1GNJ202C offers the highest stock level at 140,935 units.

Upgraded Tolerance Substitutes: AF0201FR-072KL, AC0201FR-072KL, RC0201FR-072KL, CRCW02012K00FNED, and ERJ-1GNF2001C provide ±1% tolerance, representing a tighter specification than the original ±5%. These parts are fully compatible in applications where the original tolerance is acceptable. AC0201FR-072KL and CRCW02012K00FNED extend the upper operating temperature to 155°C, providing additional thermal margin.

Extended Temperature Range: AC0201FR-072KL and CRCW02012K00FNED support -55°C to 155°C operation, compared to the original -55°C to 125°C range. Selection of these parts is appropriate when thermal headroom is required.

Packaging Considerations: RC0201FR-072KL and ERJ-1GEJ202C are supplied in Cut Tape (CT) & Digi-Reel® format rather than Tape & Reel. This packaging is suitable for lower-volume assembly processes or manual placement operations.

Obsolescence Status: ERJ-1GEJ202C is marked obsolete and should be avoided for new designs despite current inventory availability. All other substitute parts maintain active production status.

Frequently Asked Questions (FAQ)

Q: Can I substitute AF0201FR-072KL (±1% tolerance) for AF0201JR-072KL (±5% tolerance)?

A: Yes. The ±1% tolerance is a tighter specification and is fully compatible. The part will perform identically in the circuit while providing superior tolerance performance.

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

A: Tape & Reel (TR) packaging is optimized for high-speed automated assembly with reel-fed pick-and-place equipment. Cut Tape (CT) & Digi-Reel® is supplied in smaller quantities on tape strips, suitable for lower-volume production or manual assembly processes. Electrical performance is identical.

Q: Why does AC0201FR-072KL have a higher operating temperature range (-55°C to 155°C vs. -55°C to 125°C)?

A: AC0201FR-072KL uses moisture-resistant thick film construction, which provides improved thermal stability at elevated temperatures. This is a material and process difference that does not affect electrical compatibility but provides additional design margin in high-temperature applications.

Q: Is ERJ-1GEJ202C still available for new designs?

A: No. ERJ-1GEJ202C is marked obsolete and should not be selected for new designs. Use ERJ-1GNJ202C (active production equivalent) instead.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the original AF0201JR-072KL specifications.

Q: Which substitute offers the best inventory availability?

A: ERJ-1GNF2001C from Panasonic provides the highest stock level at 245,076 units. CRCW02012K00FNED from Vishay Dale offers 43,003 units with ±1% tolerance and extended temperature range.
