Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F5904CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 5.9 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical height (seated maximum), specific feature sets (anti-sulfur vs. automotive qualification), and inventory levels do not affect functional substitutability within the defined electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08055M90FKEA replace RCS2012F5904CS in non-automotive applications?

A: Yes. CRCW08055M90FKEA meets all electrical and mechanical specifications required for RCS2012F5904CS substitution. AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: Are there any height restrictions when substituting these parts?

A: The three parts have different seated heights: 0.026" (RCS2012F5904CS), 0.020" (CRCW08055M90FKEA), and 0.024" (RC0805FR-075M9L). All are within standard 0805 package specifications. Verify PCB clearance requirements for your specific design before substitution.

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

A: Yes. All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the tolerance specification, and does it affect substitutability?

A: All parts are specified at ±1% tolerance. This tolerance applies to the resistance value at 25°C and is identical across all three parts, ensuring equivalent circuit performance.

Q: Are these parts suitable for high-temperature applications?

A: Yes. All three parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, meeting standard industrial temperature requirements.

Q: Can I use RC0805FR-075M9L as a direct replacement without PCB redesign?

A: Yes. RC0805FR-075M9L is mechanically and electrically equivalent to RCS2012F5904CS. The 0.002" height difference (0.024" vs. 0.026") is within standard PCB assembly tolerances and does not require design modification.
