Frequently Asked Questions (FAQ)

Q: Can I substitute the RC2012F1961CS with any of the listed parts without circuit redesign?

A: Yes. All listed direct substitute parts maintain identical electrical specifications (1.96 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C operating range) and 0805 package footprint. Physical height variations (0.50mm to 0.70mm) are within standard PCB assembly tolerances and do not require design changes.

Q: What is the difference between parts with "Moisture Resistant" and "Automotive AEC-Q200" features?

A: Moisture Resistant indicates enhanced protection against humidity during storage and assembly. Automotive AEC-Q200 certification indicates qualification for automotive applications with additional reliability testing and performance validation. Parts with both features provide the highest level of environmental protection. Selection depends on application requirements.

Q: Why is MCR10ERTF1961 marked as discontinued?

A: MCR10ERTF1961 is discontinued at DiGi Electronics and should not be selected for new designs. Use active alternatives such as RMCF0805FT1K96, RC0805FR-071K96L, or CR0805-FX-1961ELF instead.

Q: Are there packaging format differences between substitute parts?

A: Yes. The RC2012F1961CS is supplied in Tape & Reel (TR) format. RC0805FR-071K96L is available in Cut Tape (CT) & Digi-Reel format. Both formats are compatible with standard pick-and-place assembly equipment. Verify packaging availability with your supplier based on production volume requirements.

Q: Do all substitute parts meet ROHS3 and REACH compliance?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance profile of the RC2012F1961CS.

Q: What is MSL 1 (Unlimited) and why is it important?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture-controlled storage conditions. All listed parts share this specification, ensuring compatibility with standard warehouse and assembly environments.

Q: Can I use automotive-rated parts (AEC-Q200) in non-automotive applications?

A: Yes. Automotive-rated parts exceed standard specifications and are fully compatible with non-automotive applications. Using AEC-Q200 rated parts provides additional reliability margin without circuit or assembly modifications.
