Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1874CS is determined by strict alignment of the following parameters:

Electrical Parameters (Critical):

• Resistance value: 1.87 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package format: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Termination count: 2

Compliance Parameters (Required):

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status

The ERJ-6ENF1874V from Panasonic Electronic Components meets all critical electrical, mechanical, and compliance requirements and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-6ENF1874V qualifies as a direct electrical and mechanical substitute for the RCS2012F1874CS. Both components share identical resistance values, tolerance specifications, power ratings, package dimensions, and operating temperature ranges. Both parts maintain ROHS3 compliance and REACH Unaffected status.

The ERJ-6ENF1874V carries AEC-Q200 automotive qualification, which represents an additional certification tier beyond the base RCS2012F1874CS specification. This qualification does not restrict use in non-automotive applications and indicates enhanced reliability testing and quality assurance protocols.

The maximum seated height of the ERJ-6ENF1874V is 0.028" (0.70mm) compared to 0.026" (0.66mm) for the RCS2012F1874CS. This 0.002" (0.04mm) difference remains within typical PCB assembly tolerances and does not affect functional compatibility in standard 0805 footprint designs.

Selection between these parts should be based on availability, lead time, cost considerations, and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-6ENF1874V replace the RCS2012F1874CS in all applications?

A: Yes. Both components share identical electrical specifications (1.87 MOhms ±1%, 0.125W, ±100ppm/°C), identical package dimensions (0805 / 2012 Metric), and identical compliance certifications (ROHS3, REACH Unaffected, MSL 1). The physical height difference of 0.002" (0.04mm) is within standard PCB assembly tolerances.

Q: What is the significance of the AEC-Q200 rating on the Panasonic part?

A: AEC-Q200 is an automotive industry qualification standard that certifies enhanced reliability testing and quality assurance. This certification does not restrict the component to automotive use only. Non-automotive applications may use AEC-Q200 qualified parts without limitation.

Q: Are the package dimensions truly identical?

A: The length and width dimensions are identical at 0.079" L x 0.049" W (2.00mm x 1.25mm). The maximum seated height differs by 0.002" (0.04mm): RCS2012F1874CS at 0.026" (0.66mm) and ERJ-6ENF1874V at 0.028" (0.70mm). This variation is within standard manufacturing tolerances for 0805 components and does not affect PCB assembly compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the RCS2012F1874CS and ERJ-6ENF1874V carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH Unaffected, and carry EAR99 ECCN classification with HTSUS code 8533.21.0030.
