Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F2054CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 2.05 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status
• ECCN: EAR99

All three substitute parts meet these criteria. Variations in height (seated maximum) and specific feature sets (anti-sulfur vs. automotive AEC-Q200 certification) do not affect functional substitution within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RCS2012F2054CS based on electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

CRCW08052M05FKEA (Vishay Dale): This substitute includes AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive applications. The seated height of 0.020" (0.50mm) is the lowest among all options, suitable for space-constrained PCB layouts.

ERJ-6ENF2054V (Panasonic Electronic Components): This substitute also carries AEC-Q200 automotive qualification. The seated height of 0.028" (0.70mm) is the highest among all options. Inventory availability is 29,750 pieces.

RC0805FR-072M05L (YAGEO): This substitute features moisture-resistant characteristics similar to the original RCS2012F2054CS. The seated height of 0.024" (0.60mm) provides a middle-ground option. Inventory availability is 10,384 pieces.

All parts maintain ROHS3 compliance, unlimited MSL rating, and identical electrical performance within the specified operating temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052M05FKEA replace RCS2012F2054CS in non-automotive applications?

A: Yes. The AEC-Q200 automotive qualification of CRCW08052M05FKEA does not restrict its use in non-automotive circuits. All electrical and mechanical parameters are equivalent.

Q: What is the significance of the height differences among substitute parts?

A: Height variations (0.020" to 0.028") reflect manufacturing tolerances and design differences between manufacturers. All parts remain within the 0805 (2012 Metric) package specification. Height selection depends on PCB clearance requirements and assembly constraints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—CRCW08052M05FKEA, ERJ-6ENF2054V, and RC0805FR-072M05L—are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Do the substitute parts have identical temperature coefficients?

A: Yes. All substitute parts maintain a temperature coefficient of ±100ppm/°C, matching the original RCS2012F2054CS specification.

Q: Which substitute part should be selected for high-reliability applications?

A: CRCW08052M05FKEA and ERJ-6ENF2054V both carry AEC-Q200 automotive qualification, indicating enhanced reliability screening and qualification. Selection between these two depends on PCB layout constraints (height considerations) and supplier availability.

Q: Are there any packaging differences among the substitute parts?

A: All parts are supplied in Tape & Reel (TR) packaging. Electrical and mechanical specifications are identical across all options.
