Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F1180CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 118 Ohms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical across all substitutes.

Package Compatibility: All substitute parts must use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm).

Environmental Specifications: Operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C must be maintained.

Composition & Construction: All substitutes utilize thick film construction to ensure equivalent performance characteristics.

Compliance & Certifications: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

Packaging Format: All parts are supplied in Tape & Reel (TR) format for automated assembly compatibility.

The three identified substitutes meet all these criteria and are therefore electrically and mechanically interchangeable with the RCS2012F1180CS.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are Active in product status and maintain full ROHS3 compliance and REACH unaffected designation, ensuring regulatory compatibility with the RCS2012F1180CS.

CRCW0805118RFKEA (Vishay Dale): This substitute carries Automotive AEC-Q200 qualification, providing enhanced reliability for automotive and high-reliability applications. The seated height of 0.020" (0.50mm) is the lowest among all options, offering potential advantages in space-constrained PCB designs.

ERJ-6ENF1180V (Panasonic Electronic Components): This substitute also carries Automotive AEC-Q200 qualification. With the highest seated height of 0.028" (0.70mm), it remains within acceptable clearance tolerances for standard PCB assembly. Panasonic's ERJ-6EN series provides established automotive-grade reliability.

RC0805FR-07118RL (YAGEO): This substitute features moisture-resistant properties matching the original RCS2012F1180CS specification. The seated height of 0.024" (0.60mm) provides a mid-range profile suitable for general industrial applications. YAGEO's RC_L series offers cost-effective performance for non-automotive applications.

Selection among these substitutes depends on application requirements: automotive-grade applications benefit from AEC-Q200 qualified parts (Vishay Dale or Panasonic), while general industrial applications may utilize the YAGEO option.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805118RFKEA replace RCS2012F1180CS in any application?

A: Yes, the CRCW0805118RFKEA is electrically and mechanically equivalent. Both parts share identical resistance (118 Ohms), tolerance (±1%), power rating (0.125W), package (0805), temperature range (-55°C to 155°C), and compliance status (ROHS3). The primary difference is the addition of Automotive AEC-Q200 qualification on the Vishay part, which provides enhanced reliability for automotive applications.

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

A: The seated height varies slightly: RCS2012F1180CS at 0.026" (0.66mm), CRCW0805118RFKEA at 0.020" (0.50mm), ERJ-6ENF1180V at 0.028" (0.70mm), and RC0805FR-07118RL at 0.024" (0.60mm). These variations remain within standard 0805 package tolerances and do not affect PCB assembly compatibility. Height differences may be relevant only in applications with extremely tight vertical clearance constraints.

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

A: Yes, all substitute parts are supplied in Tape & Reel (TR) format, ensuring compatibility with automated pick-and-place assembly equipment used for the original RCS2012F1180CS.

Q: Which substitute part is recommended for automotive applications?

A: Both CRCW0805118RFKEA (Vishay Dale) and ERJ-6ENF1180V (Panasonic) carry Automotive AEC-Q200 qualification, making them suitable for automotive-grade applications. The RC0805FR-07118RL (YAGEO) is qualified for general industrial use.

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

A: Yes, all substitute parts maintain MSL 1 (Unlimited) rating, identical to the RCS2012F1180CS, indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the temperature coefficient specification across all parts?

A: All parts, including the RCS2012F1180CS and all three substitutes, maintain a temperature coefficient of ±100ppm/°C, ensuring consistent performance across the -55°C to 155°C operating range.
