Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1182CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (11.8 kOhms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and number of terminations (2) ensure physical fit and solderability on printed circuit boards. Dimensional alignment (0.079" L x 0.049" W / 2.00mm x 1.25mm) is mandatory for automated assembly processes.

Compliance & Environmental: RoHS3 compliance, MSL Level 1 rating, and REACH unaffected status are required for regulatory equivalence. Composition (thick film) and packaging format (Tape & Reel) must match the original specification.

All four substitute parts listed meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F1182CS based on electrical and mechanical parameter alignment. Selection among these alternatives is determined by application-specific requirements and supply chain considerations:

CRCW080511K8FKEA (Vishay Dale): Automotive AEC-Q200 rated. Seated height 0.020" (0.50mm), the lowest profile among substitutes. Suitable for space-constrained automotive and industrial applications requiring automotive-grade qualification.

ERJ-6ENF1182V (Panasonic Electronic Components): Automotive AEC-Q200 rated. Seated height 0.028" (0.70mm), the highest profile. Highest inventory availability (72,597 pcs). Suitable for automotive applications with standard clearance requirements.

RC0805FR-0711K8L (YAGEO): Non-automotive rated, moisture-resistant composition. Seated height 0.024" (0.60mm). Suitable for consumer and industrial applications without automotive qualification requirements.

RMCF0805FT11K8 (Stackpole Electronics Inc): Automotive AEC-Q200 rated. Seated height 0.026" (0.65mm). Highest inventory availability (136,836 pcs). Suitable for automotive applications with standard clearance and cost optimization priorities.

All parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. Height variations (0.50mm to 0.70mm) are within typical PCB assembly tolerances for 0805 packages.

Frequently Asked Questions (FAQ)

Q: Can CRCW080511K8FKEA replace RCS2012F1182CS in non-automotive applications?

A: Yes. Automotive AEC-Q200 qualification is a superset of standard thick film resistor performance. The CRCW080511K8FKEA meets all electrical and mechanical specifications of the RCS2012F1182CS and is suitable for any application within the specified operating temperature range (-55°C ~ 155°C).

Q: What is the significance of the height variation between substitute parts?

A: Seated height ranges from 0.020" (0.50mm) to 0.028" (0.70mm). This variation affects clearance to adjacent components and PCB assembly process parameters. All values remain within standard 0805 package tolerances. Verify clearance requirements in your specific PCB layout before selection.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All four substitute parts are supplied in Tape & Reel (TR) format, matching the original RCS2012F1182CS packaging specification for automated assembly compatibility.

Q: What is the difference between automotive AEC-Q200 rated and non-automotive rated resistors?

A: AEC-Q200 qualification indicates compliance with automotive industry reliability and environmental stress testing standards. CRCW080511K8FKEA, ERJ-6ENF1182V, and RMCF0805FT11K8 carry this rating. RC0805FR-0711K8L does not. For non-automotive applications, both rated and non-rated parts are functionally equivalent.

Q: Do all substitute parts have identical moisture sensitivity levels?

A: Yes. All parts, including the original RCS2012F1182CS, are rated MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part offers the best inventory availability?

A: RMCF0805FT11K8 (Stackpole Electronics Inc) has the highest inventory level at 136,836 pcs. ERJ-6ENF1182V (Panasonic) is second with 72,597 pcs. Both are suitable for high-volume procurement scenarios.

Q: Are tolerance and temperature coefficient specifications identical across all parts?

A: Yes. All parts maintain ±1% tolerance and ±100ppm/°C temperature coefficient, ensuring equivalent precision and thermal stability across the operating temperature range of -55°C ~ 155°C.
