Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012J3R6CS are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 3.6 Ohms with tolerance specifications of ±5% or tighter (±1% acceptable as upgrade).

Mechanical Compatibility: 0805 (2012 Metric) package format with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and two terminations.

Environmental Specifications: Operating temperature range of -55°C ~ 155°C, MSL 1 rating, and RoHS3 compliance.

Composition: Thick film construction with moisture-resistant properties.

Packaging: Tape & Reel (TR) format for automated assembly compatibility.

Substitutes are grouped by tolerance specification and additional certifications (automotive AEC-Q200 qualification where applicable).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Specifications): RC0805JR-073R6L (YAGEO) and RMCF0805JT3R60 (Stackpole) are direct electrical and mechanical equivalents to RC2012J3R6CS. Both maintain ±5% tolerance, 0.125W power rating, and identical operating temperature range. All three parts are RoHS3 compliant with MSL 1 rating. Selection between these options depends on inventory availability and supply chain requirements.

Upgraded Tolerance Option: RMCF0805FT3R60 (Stackpole) provides tighter ±1% tolerance while maintaining all other electrical and mechanical specifications. This part is suitable for applications requiring improved accuracy. The Stackpole RMCF series includes AEC-Q200 automotive qualification, applicable for automotive-grade circuit designs.

Compliance Considerations: All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original RC2012J3R6CS. MSL 1 rating across all options indicates unlimited moisture sensitivity protection.

Frequently Asked Questions (FAQ)

Q: Can RC0805JR-073R6L replace RC2012J3R6CS in existing designs? A: Yes. RC0805JR-073R6L is electrically and mechanically equivalent with identical 3.6 Ohm resistance, ±5% tolerance, 0.125W power rating, and 0805 package format. Both components operate across -55°C ~ 155°C and carry RoHS3 compliance.

Q: What is the difference between RMCF0805FT3R60 and RMCF0805JT3R60? A: Both are Stackpole RMCF series resistors in 0805 package with 3.6 Ohm resistance. RMCF0805FT3R60 has ±1% tolerance, while RMCF0805JT3R60 has ±5% tolerance. Both include AEC-Q200 automotive qualification and ±200ppm/°C temperature coefficient.

Q: Are all substitute parts suitable for automated assembly? A: Yes. All listed substitutes are packaged in Tape & Reel (TR) format compatible with standard pick-and-place assembly equipment. Package dimensions and termination count (2) are identical across all options.

Q: Does tolerance difference affect circuit performance? A: Tolerance affects resistor value accuracy. RC2012J3R6CS and equivalents with ±5% tolerance allow 3.42 ~ 3.78 Ohm variation. RMCF0805FT3R60 with ±1% tolerance restricts variation to 3.564 ~ 3.636 Ohms. Selection depends on circuit accuracy requirements.

Q: Are height differences significant for PCB layout? A: RC0805JR-073R6L has maximum seated height of 0.024" (0.60mm), while RC2012J3R6CS, RMCF0805FT3R60, and RMCF0805JT3R60 are 0.026" (0.65mm). This 0.002" difference is negligible for standard PCB designs but should be verified for space-constrained applications.

Q: What does AEC-Q200 qualification mean? A: AEC-Q200 is an automotive electronics qualification standard. RMCF series parts with this rating are qualified for automotive applications. Non-automotive designs can use these parts without restriction.

Q: Are all parts RoHS3 compliant? A: Yes. RC2012J3R6CS and all substitute parts listed are ROHS3 compliant, meeting EU Restriction of Hazardous Substances requirements.
