Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F1184CS are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent Category: Parts that match all critical electrical parameters (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical specifications (0805 package, 2-termination configuration) without additional certifications or feature modifications.

Similar Category with Enhanced Features: Parts that maintain identical electrical and mechanical specifications but include additional automotive AEC-Q200 qualification. These parts are suitable for applications requiring automotive-grade reliability standards.

Key Parameters Determining Substitution Eligibility:

• Resistance: 1.18 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• RoHS Compliance: ROHS3 (exact match required)

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-071M18L (YAGEO): This part is a direct electrical and mechanical equivalent to the RC2012F1184CS. All critical parameters including resistance, tolerance, power rating, temperature coefficient, and operating temperature range are identical. The component maintains ROHS3 compliance and MSL 1 rating. Selection of this part is appropriate for applications where the original Samsung component is unavailable and automotive certification is not required.

CRCW08051M18FKEA (Vishay Dale): This part meets all electrical and mechanical specifications of the RC2012F1184CS and includes AEC-Q200 automotive qualification. The seated height is 0.020" (0.50mm), which is lower than the original part at 0.026" (0.66mm). This part is suitable for applications requiring automotive-grade reliability or where enhanced qualification standards are specified. ROHS3 compliance and MSL 1 rating are maintained.

ERJ-6ENF1184V (Panasonic Electronic Components): This part meets all electrical and mechanical specifications of the RC2012F1184CS and includes AEC-Q200 automotive qualification. The seated height is 0.028" (0.70mm), which is higher than the original part at 0.026" (0.66mm). This part is suitable for applications requiring automotive-grade reliability or where enhanced qualification standards are specified. ROHS3 compliance and MSL 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071M18L be used as a direct replacement for RC2012F1184CS?

A: Yes. The RC0805FR-071M18L is electrically and mechanically equivalent. Both components share identical resistance (1.18 MOhms), tolerance (±1%), power rating (0.125W), package format (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the substitute parts?

A: The primary difference is automotive certification. CRCW08051M18FKEA and ERJ-6ENF1184V both include AEC-Q200 automotive qualification, while RC0805FR-071M18L does not. All four parts (including the original RC2012F1184CS) are electrically identical. Secondary differences exist in seated height: CRCW08051M18FKEA at 0.020" (0.50mm), RC2012F1184CS at 0.026" (0.66mm), RC0805FR-071M18L at 0.024" (0.60mm), and ERJ-6ENF1184V at 0.028" (0.70mm).

Q: Are the substitute parts suitable for automotive applications?

A: CRCW08051M18FKEA and ERJ-6ENF1184V carry AEC-Q200 automotive qualification. RC0805FR-071M18L does not specify automotive certification. Selection depends on application requirements.

Q: Does package compatibility affect substitution?

A: All substitute parts use the 0805 (2012 Metric) package format, which is mechanically compatible with the original RC2012F1184CS. Seated height variations (0.020" to 0.028") are within typical PCB assembly tolerances for surface-mount components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC0805FR-071M18L, CRCW08051M18FKEA, and ERJ-6ENF1184V are all ROHS3 compliant, matching the original RC2012F1184CS specification.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All listed parts, including the original and substitutes, carry this rating.
