Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F1741CS are qualified based on the following critical parameters that determine functional and mechanical compatibility:

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)
• Number of terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore suitable for direct replacement in circuit applications where the RCS2012F1741CS is specified.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS2012F1741CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the critical electrical parameters (1.74 kΩ ±1%, 0.125W), mechanical package (0805), composition (thick film), and compliance requirements (ROHS3, MSL 1). Direct PCB replacement is supported.

Q: What is the difference between automotive-qualified and non-automotive-qualified substitutes?

A: Automotive-qualified parts (AC0805FR-071K74L, CRCW08051K74FKEA, ERJ-6ENF1741V, RMCF0805FT1K74) carry AEC-Q200 certification. Non-automotive parts (RC0805FR-071K74L) do not carry this certification. Selection depends on application requirements.

Q: Are there height differences between substitute parts that affect PCB assembly?

A: Yes. Seated heights range from 0.50mm (CRCW08051K74FKEA) to 0.70mm (ERJ-6ENF1741V). The RCS2012F1741CS reference height is 0.66mm. For space-constrained designs, CRCW08051K74FKEA offers the lowest profile.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the RCS2012F1741CS, are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part has the best inventory availability?

A: RC0805FR-071K74L (YAGEO) has the highest inventory at 174,578 pcs. For automotive applications, ERJ-6ENF1741V (Panasonic) offers 101,171 pcs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the environmental compliance requirement of the RCS2012F1741CS.
