Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (41.2 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99). All identified substitutes meet these core electrical and mechanical requirements. Operating temperature range variations and product status differences are noted but do not disqualify substitution where electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

RC0201FR-0741K2L (YAGEO) is the primary upgrade substitute, offering active product status, significantly higher inventory (43,296 units), and identical electrical specifications. This part is suitable for applications where the -55°C to 125°C operating range is acceptable.

CRCW020141K2FNED (Vishay Dale) provides an alternative from a different manufacturer with active status and full -55°C to 155°C temperature range matching the original specification. Inventory availability is moderate at 1,125 units.

ERJ-1GNF4122C (Panasonic Electronic Components) is an active product with the highest inventory level (44,839 units) and meets all electrical requirements, though operating temperature is limited to -55°C to 125°C.

RK73H1HTTC4122F (KOA Speer Electronics) maintains the full -55°C to 155°C range and automotive AEC-Q200 qualification matching the original part, but carries "Not For New Designs" status with substantial inventory (23,566 units). This part is suitable for legacy system support or replacement applications.

ERJ-1GEF4122C (Panasonic Electronic Components) is marked obsolete and should be avoided for new designs despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0741K2L replace AC0201FR-0741K2L in all applications? A: RC0201FR-0741K2L is electrically equivalent with identical resistance, tolerance, power rating, and temperature coefficient. The operating temperature range is -55°C to 125°C versus -55°C to 155°C on the original. Substitution is valid for applications operating within the -55°C to 125°C window.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Both are standard SMD packaging formats. Tape & Reel is continuous reel packaging for automated assembly. Cut Tape & Digi-Reel is pre-cut tape format. Both are compatible with standard pick-and-place equipment; packaging choice depends on assembly line requirements and minimum order quantities.

Q: Why is ERJ-1GEF4122C marked obsolete? A: Panasonic has discontinued this product line in favor of the ERJ-1GNF4122C series. While inventory remains available, new designs should specify ERJ-1GNF4122C for long-term supply assurance.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original AC0201FR-0741K2L compliance status.

Q: Which substitute offers the best inventory availability? A: ERJ-1GNF4122C (Panasonic) provides the highest inventory at 44,839 units, followed by RC0201FR-0741K2L (YAGEO) at 43,296 units.

Q: Can I use RK73H1HTTC4122F for new designs? A: RK73H1HTTC4122F carries "Not For New Designs" status. It is suitable only for replacement, repair, or legacy system applications. For new designs, select from active status parts: RC0201FR-0741K2L, CRCW020141K2FNED, or ERJ-1GNF4122C.
