Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F7R5CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 7.5 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Thick Film

Mechanical Parameters (Must Match):

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

Environmental & Compliance Parameters (Must Match or Exceed):

• Operating temperature range: -55°C ~ 155°C minimum
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance
• REACH Unaffected status

Substitutes are grouped by manufacturer while maintaining identical core electrical and mechanical specifications. Temperature coefficient variations and additional certifications (such as AEC-Q200 automotive qualification) do not disqualify parts from substitution eligibility when all mandatory parameters align.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-077R5L (YAGEO): This substitute maintains all mandatory electrical and mechanical specifications with identical resistance, tolerance, and power rating. The component achieves a lower temperature coefficient (±200ppm/°C versus ±300ppm/°C) and slightly reduced seated height (0.024" versus 0.026"), both favorable characteristics. Active product status and full RoHS3/REACH compliance confirm ongoing availability and regulatory alignment.

RMCF0805FT7R50 (Stackpole Electronics Inc): This substitute qualifies through identical core electrical parameters and mechanical dimensions. The addition of AEC-Q200 automotive qualification provides enhanced reliability documentation for applications requiring automotive-grade components. Temperature coefficient matches YAGEO specification at ±200ppm/°C. Seated height equals the original Samsung part at 0.026". Active product status ensures supply continuity.

Both substitutes are interchangeable with the RC2012F7R5CS based on provided specifications. Selection between alternatives depends on application-specific requirements regarding automotive certification and temperature coefficient performance.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-077R5L replace RC2012F7R5CS in all applications?

A: Yes, when electrical specifications (7.5 Ohms ±1%, 0.125W) and mechanical package (0805) are the only selection criteria. The YAGEO part maintains identical resistance, tolerance, power rating, operating temperature range, and compliance certifications. The lower temperature coefficient (±200ppm/°C) and reduced seated height represent equivalent or improved performance characteristics.

Q: What is the difference between RMCF0805FT7R50 and the other substitutes?

A: RMCF0805FT7R50 includes AEC-Q200 automotive qualification, indicating enhanced reliability testing and documentation for automotive applications. All three parts share identical electrical specifications (7.5 Ohms ±1%, 0.125W), package format (0805), and environmental ratings (-55°C ~ 155°C). The Stackpole part's temperature coefficient (±200ppm/°C) matches YAGEO but differs from Samsung's ±300ppm/°C specification.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Seated height variations (0.024" to 0.026") fall within standard PCB assembly tolerances and do not affect placement or soldering processes.

Q: Do all substitutes meet RoHS3 and REACH requirements?

A: Yes. RC0805FR-077R5L, RMCF0805FT7R50, and the original RC2012F7R5CS are all ROHS3 Compliant with REACH Unaffected status, confirming regulatory compliance for EU and global markets.

Q: Which substitute should be selected for automotive applications?

A: RMCF0805FT7R50 carries AEC-Q200 automotive qualification, providing documented reliability for automotive-grade component requirements. RC0805FR-077R5L and RC2012F7R5CS lack this specific certification and should be evaluated against application-specific automotive standards if required.

Q: Is temperature coefficient variation significant between substitutes?

A: Temperature coefficient differences (±300ppm/°C versus ±200ppm/°C) affect resistance stability across temperature extremes. Applications requiring minimal resistance drift across the -55°C ~ 155°C operating range benefit from the lower coefficient of YAGEO and Stackpole parts. Standard applications typically tolerate both specifications within design margins.
