Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F2R2CS is determined by strict equivalence across the following parameters:

Mandatory Electrical Parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)

Mandatory Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Mandatory Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Allowed Variation Parameters:

• Temperature coefficient: ±200ppm/°C to ±300ppm/°C
• Height - Seated (Max): 0.024" to 0.028" (0.60mm to 0.70mm)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Additional features: Moisture Resistant, Automotive AEC-Q200, Current Sense

All three substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RC2012F2R2CS.

Parameter Comparison

Engineering Selection Recommendations

ERJ-6RQF2R2V (Panasonic Electronic Components)

This substitute is qualified to AEC-Q200 automotive standard and includes current sense capability. Selection is appropriate for applications requiring automotive-grade reliability and extended supply chain availability (34,457 units in stock). Temperature coefficient of ±200ppm/°C provides improved stability compared to the original part. Maximum seated height of 0.028" (0.70mm) remains within acceptable PCB assembly tolerances.

RC0805FR-072R2L (YAGEO)

This substitute maintains moisture-resistant thick film construction identical to the original specification. Temperature coefficient of ±200ppm/°C offers improved thermal stability. Maximum seated height of 0.024" (0.60mm) is the lowest among all options, providing optimal clearance for dense PCB layouts. Extensive inventory availability (77,251 units) supports high-volume production requirements.

RMCF0805FT2R20 (Stackpole Electronics Inc)

This substitute is qualified to AEC-Q200 automotive standard and maintains identical packaging format (Tape & Reel) to the original part, eliminating packaging conversion requirements. Temperature coefficient of ±200ppm/°C and maximum seated height of 0.026" (0.65mm) match the original specifications precisely. Largest inventory availability (242,050 units) ensures consistent supply for extended production runs.

All three substitutes are Active product status with full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance across global markets.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6RQF2R2V be used as a direct replacement for RC2012F2R2CS?

A: Yes. Both components share identical electrical specifications (2.2 Ohms ±1%, 0.125W), package type (0805), and compliance certifications (RoHS3, REACH Unaffected, MSL 1). The ERJ-6RQF2R2V includes AEC-Q200 automotive qualification as an additional feature. Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which may require supply chain adjustment but does not affect electrical or mechanical compatibility.

Q: What is the significance of the ±200ppm/°C temperature coefficient in substitute parts compared to the original ±300ppm/°C?

A: Temperature coefficient defines resistance change per degree Celsius. The ±200ppm/°C specification in substitute parts indicates tighter resistance stability across the -55°C to 155°C operating range. This represents improved performance and is acceptable for all applications where the original ±300ppm/°C specification was suitable.

Q: Are there height differences that affect PCB assembly?

A: Maximum seated heights range from 0.024" (0.60mm) to 0.028" (0.70mm). All values remain within standard 0805 package specifications and PCB assembly tolerances. The RC0805FR-072R2L offers the lowest profile at 0.024", beneficial for space-constrained designs. The ERJ-6RQF2R2V at 0.028" remains fully compatible with standard pick-and-place equipment.

Q: Which substitute part should be selected for automotive applications?

A: Both ERJ-6RQF2R2V and RMCF0805FT2R20 carry AEC-Q200 automotive qualification. RMCF0805FT2R20 maintains identical Tape & Reel packaging to the original part, simplifying supply chain integration. ERJ-6RQF2R2V includes current sense capability as an additional feature. Selection depends on packaging format requirements and supply chain preferences.

Q: Does packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affect component performance?

A: No. Packaging format affects only logistics, storage, and assembly line handling. Electrical and mechanical performance is identical regardless of packaging format. Selection should be based on manufacturing equipment compatibility and supply chain requirements.

Q: Are all substitute parts in active production status?

A: Yes. All three substitute parts—ERJ-6RQF2R2V, RC0805FR-072R2L, and RMCF0805FT2R20—maintain Active product status with full inventory availability, ensuring long-term supply continuity.
