Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F2R7CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 2.7 Ohms
• Tolerance: ±1%
• Operating temperature range: -55°C ~ 155°C
• Composition: Thick Film

Mechanical Parameters (Must Match):

• Package / Case: 0805 (2012 Metric)
• Supplier Device Package: 0805
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Power Rating Substitution Logic: Substitute parts with equal or higher power ratings (0.125W or greater) are acceptable. Parts with lower power ratings are not qualified substitutes.

Three substitute parts meet these criteria with variations in power rating and automotive qualification:

1. ERJ-6RQF2R7V (Panasonic) – Direct electrical equivalent with AEC-Q200 automotive qualification
2. RMCF0805FT2R70 (Stackpole Electronics) – Direct electrical equivalent with AEC-Q200 automotive qualification
3. ERJ-6BQF2R7V (Panasonic) – Higher power rating (0.333W) with AEC-Q200 automotive qualification

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for Standard Applications):

ERJ-6RQF2R7V and RMCF0805FT2R70 are direct electrical and mechanical equivalents to the RC2012F2R7CS. Both parts maintain identical resistance, tolerance, power rating, and package specifications. Both substitute parts carry AEC-Q200 automotive qualification, which exceeds the compliance requirements of the original Samsung component. The temperature coefficient improvement (±200ppm/°C versus ±300ppm/°C) provides enhanced stability across the operating temperature range.

Higher Power Rating Alternative:

ERJ-6BQF2R7V provides a higher power rating (0.333W versus 0.125W) while maintaining all other electrical and mechanical parameters. This part is suitable for applications where thermal margin or future design flexibility is required. The increased height (0.028" versus 0.026") must be verified against PCB layout constraints.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original component's regulatory standing. The addition of AEC-Q200 automotive qualification on substitute parts does not restrict their use in non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6RQF2R7V be used as a direct replacement for RC2012F2R7CS?

A: Yes. ERJ-6RQF2R7V is a direct electrical and mechanical equivalent. Both parts share identical resistance (2.7 Ohms), tolerance (±1%), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). The maximum seated height difference (0.028" versus 0.026") is within typical PCB assembly tolerances.

Q: What is the difference between ERJ-6RQF2R7V and ERJ-6BQF2R7V?

A: The primary difference is power rating. ERJ-6RQF2R7V is rated at 0.125W (1/8W), matching the original RC2012F2R7CS. ERJ-6BQF2R7V is rated at 0.333W (1/3W), providing higher thermal capacity. Both parts are identical in resistance, tolerance, package, and operating temperature. The higher power rating of ERJ-6BQF2R7V results in a maximum seated height of 0.028" compared to 0.026" for the 1/8W version.

Q: Is RMCF0805FT2R70 compatible with the RC2012F2R7CS in terms of package dimensions?

A: Yes. RMCF0805FT2R70 maintains the same 0805 (2012 Metric) package footprint and dimensions (0.079" L x 0.049" W). The maximum seated height is 0.026", identical to the original Samsung component, ensuring compatibility with existing PCB layouts.

Q: Do the substitute parts have better temperature stability than the original RC2012F2R7CS?

A: The substitute parts ERJ-6RQF2R7V, RMCF0805FT2R70, and ERJ-6BQF2R7V all feature a temperature coefficient of ±200ppm/°C, compared to ±300ppm/°C for the RC2012F2R7CS. This represents improved temperature stability across the -55°C ~ 155°C operating range.

Q: Are the substitute parts suitable for automotive applications?

A: All three substitute parts carry AEC-Q200 automotive qualification. The original RC2012F2R7CS does not specify automotive qualification. This means substitute parts can be used in both automotive and non-automotive applications where the original component was specified.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations and does not require special moisture control during storage, handling, or assembly. All parts in this comparison share this rating, ensuring equivalent moisture management requirements.

Q: Can I use ERJ-6BQF2R7V in a design that specifies RC2012F2R7CS?

A: ERJ-6BQF2R7V is electrically compatible (2.7 Ohms, ±1%, -55°C ~ 155°C) and mechanically compatible (0805 package). The higher power rating (0.333W versus 0.125W) does not create incompatibility. However, the maximum seated height increases from 0.026" to 0.028", which must be verified against PCB assembly clearance specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC2012F2R7CS, ERJ-6RQF2R7V, RMCF0805FT2R70, and ERJ-6BQF2R7V are all ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory compliance.
