Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4124CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (4.12 MOhms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package format (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and number of terminations (2) ensure PCB footprint compatibility.

Compliance & Environmental: RoHS3 compliance, MSL Level 1 rating, and REACH unaffected status confirm regulatory alignment. Composition (Thick Film) and moisture-resistant features maintain functional equivalence.

The substitute part RC0805FR-074M12L from YAGEO meets all these criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RC2012F4124CS and RC0805FR-074M12L are Active status products with full ROHS3 compliance and REACH unaffected certification. The RC0805FR-074M12L from YAGEO provides direct electrical and mechanical substitution with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The seated height differential (0.026" versus 0.024") remains within acceptable PCB assembly tolerances for 0805 package components. Both components maintain MSL Level 1 rating, eliminating moisture sensitivity constraints. Selection between these parts may be based on inventory availability, supply chain considerations, or established supplier qualification requirements, as electrical and compliance performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074M12L replace RC2012F4124CS in existing designs?

A: Yes. Both components share identical electrical specifications (4.12 MOhms ±1%, 0.125W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical compatibility (0805 package, 2.00mm x 1.25mm dimensions). No circuit redesign is required.

Q: Are there differences in physical dimensions between these parts?

A: The seated height differs slightly: RC2012F4124CS measures 0.026" (0.66mm) maximum, while RC0805FR-074M12L measures 0.024" (0.60mm) maximum. Both remain within standard 0805 package tolerances and do not affect PCB assembly or functionality.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC2012F4124CS and RC0805FR-074M12L are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental requirements are equivalent.

Q: What determines substitution eligibility for 0805 chip resistors?

A: Substitution requires matching resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package format, and compliance certifications. Composition (Thick Film) and moisture-resistant features must also align. The RC0805FR-074M12L meets all these criteria for the RC2012F4124CS.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both components operate across -55°C to 155°C with identical temperature coefficients (±100ppm/°C), ensuring consistent performance in thermal environments within this range.
