Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012J1R0CS is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 1 Ohms
• Tolerance: ±5%
• Power rating: 0.125W (1/8W)
• Package type: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±300ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Compliance: ROHS3 Compliant, REACH Unaffected

The RC2012J1R0CS from Samsung Electro-Mechanics meets all critical electrical and mechanical parameters. Variations in packaging format (Tape & Reel versus Cut Tape) and minor differences in seated height (0.66mm versus 0.65mm) do not affect functional equivalence or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RC2012J1R0CS is a direct functional equivalent to the RCS2012J1R0CS. Both components are manufactured by Samsung Electro-Mechanics and share identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction is packaging format: the main part is supplied in Tape & Reel format, while the substitute is supplied in Cut Tape format. This difference affects handling and assembly processes but does not impact component performance or board-level functionality.

Both parts maintain Active product status and full compliance with ROHS3 and REACH requirements. The marginal difference in maximum seated height (0.01mm) is within typical PCB assembly tolerances and does not affect placement or soldering operations.

Selection between these parts should be based on supply chain availability, packaging requirements for manufacturing processes, and inventory management considerations rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can RC2012J1R0CS replace RCS2012J1R0CS in production?

A: Yes. Both components are electrically and mechanically equivalent. The RC2012J1R0CS meets all critical parameters including resistance value, tolerance, power rating, package dimensions, and compliance certifications. Packaging format differences (Cut Tape versus Tape & Reel) do not affect functional compatibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on cut segments of carrier tape, typically used for manual assembly or lower-volume applications. Both formats contain identical components with no electrical or mechanical differences.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components have identical length and width dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). The maximum seated height differs by 0.01mm (0.66mm versus 0.65mm), which is within standard PCB assembly tolerances and does not affect placement or functionality.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RCS2012J1R0CS and RC2012J1R0CS are ROHS3 Compliant and REACH Unaffected. Both maintain Moisture Sensitivity Level 1 (Unlimited) classification.

Q: What determines substitution eligibility for 0805 chip resistors?

A: Substitution eligibility is determined by matching resistance value, tolerance, power rating, package type, composition, temperature coefficient, operating temperature range, physical dimensions, and compliance certifications. All these parameters must align for functional equivalence.
