Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F1741CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.74 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)
• REACH Unaffected status (required)

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 certification or enhanced moisture resistance represent supplementary capabilities that do not disqualify substitution but may provide enhanced performance for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical equivalence to the RC2012F1741CS. Selection among these alternatives is based on the following factors:

Standard Industrial Applications: RC0805FR-071K74L (YAGEO) and RC2012F1741CS (Samsung Electro-Mechanics) are functionally equivalent for general-purpose applications. Both feature moisture-resistant thick film construction with identical electrical specifications.

Automotive Applications: ERJ-6ENF1741V (Panasonic), KTR10EZPF1741 (Rohm), RMCF0805FT1K74 (Stackpole), AC0805FR-071K74L (YAGEO), and CRCW08051K74FKEA (Vishay Dale) carry Automotive AEC-Q200 certification. These parts are suitable for automotive-grade applications requiring enhanced reliability qualification.

High-Voltage Applications: KTR10EZPF1741 (Rohm Semiconductor) includes high-voltage capability designation in addition to AEC-Q200 automotive qualification.

Space-Constrained Designs: CRCW08051K74FKEA (Vishay Dale) offers the lowest seated height at 0.50mm maximum, compared to 0.65mm for the main part. AC0805FR-071K74L (YAGEO) and RC0805FR-071K74L (YAGEO) provide 0.60mm maximum height.

Inventory Availability: RC0805FR-071K74L (YAGEO) maintains the highest inventory level at 174,578 pieces. ERJ-6ENF1741V (Panasonic) provides 101,171 pieces. All parts maintain Active product status.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF1741V replace RC2012F1741CS in a standard circuit?

A: Yes. ERJ-6ENF1741V meets all electrical and mechanical specifications of RC2012F1741CS. The Automotive AEC-Q200 certification represents an additional qualification that does not prevent use in non-automotive applications. The maximum seated height difference (0.70mm vs 0.65mm) is negligible for most PCB designs.

Q: What is the difference between moisture-resistant and non-moisture-resistant variants?

A: RC2012F1741CS and RC0805FR-071K74L (YAGEO) explicitly feature moisture-resistant thick film construction. All identified parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling. The moisture-resistant designation indicates enhanced performance characteristics in high-humidity environments.

Q: Are all substitute parts suitable for automotive applications?

A: Five of the six substitute parts carry Automotive AEC-Q200 certification: ERJ-6ENF1741V, KTR10EZPF1741, RMCF0805FT1K74, AC0805FR-071K74L, and CRCW08051K74FKEA. RC0805FR-071K74L does not carry this certification. For automotive applications, select from the AEC-Q200 qualified parts.

Q: Does package height variation affect PCB assembly?

A: All parts use 0805 (2012 Metric) package format with seated heights ranging from 0.50mm to 0.70mm. This 0.20mm maximum variation is within standard PCB assembly tolerances and does not require design modification. Component placement and reflow profiles remain unchanged.

Q: Can I mix different manufacturers' parts in the same production run?

A: Yes. All identified parts meet identical electrical specifications (1.74 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical requirements (0805 package, 2 terminations, ROHS3 compliant, MSL 1). Substitution between manufacturers does not require circuit redesign or performance re-qualification.

Q: What is the significance of AEC-Q200 certification?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Parts carrying this certification have undergone enhanced reliability testing and are approved for automotive-grade applications. Non-automotive applications do not require this certification but may benefit from the enhanced qualification.

Q: Which substitute offers the best availability?

A: RC0805FR-071K74L (YAGEO) maintains the highest inventory at 174,578 pieces. For immediate availability with automotive qualification, ERJ-6ENF1741V (Panasonic) provides 101,171 pieces.
