RC0603J274CS Equivalent & Substitute Parts Reference

Part Overview

The RC0603J274CS is a 270 kOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.05W (1/20W) in a 0201 (0603 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design flexibility permits equivalent component selection from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603J274CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 270 kOhms (exact match required)
• Tolerance: ±5% (equivalent tolerance classification)
• Power rating: 0.05W minimum (equal or greater capacity acceptable)
• Package / Case: 0201 (0603 Metric) (identical footprint required for PCB compatibility)
• Composition: Thick Film (same manufacturing technology)
• Temperature coefficient: ±250ppm/°C (equivalent stability specification)
• Operating temperature range: -55°C ~ 125°C minimum (equal or wider range acceptable)
• RoHS3 compliance: Required (regulatory requirement)
• MSL rating: 1 (Unlimited) (equivalent or superior moisture resistance acceptable)

The MCR006YRTJ274 manufactured by Rohm Semiconductor meets all mandatory matching parameters and qualifies as a direct electrical and mechanical substitute. Both components share identical resistance, tolerance, power rating, package dimensions, composition, temperature coefficient, and operating temperature specifications. Both components maintain RoHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MCR006YRTJ274 (Rohm Semiconductor) is electrically and mechanically equivalent to the RC0603J274CS (Samsung Electro-Mechanics) based on complete parameter alignment. Both components satisfy identical electrical specifications, physical form factors, and regulatory requirements.

Product Status Consideration: The MCR006YRTJ274 is listed as Discontinued at DiGi Electronics. This status indicates the part is no longer actively distributed through this channel, though inventory may remain available through alternative suppliers. Selection of this substitute should account for long-term availability constraints.

Compliance Status: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in applications subject to these requirements. Both components carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Packaging Consideration: The RC0603J274CS is supplied in Tape & Reel (TR) format, while the MCR006YRTJ274 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly process requirements and volume specifications.

Frequently Asked Questions (FAQ)

Q: Can the MCR006YRTJ274 be used as a direct replacement for the RC0603J274CS in existing designs?

A: Yes. The MCR006YRTJ274 meets all electrical and mechanical specifications required for direct substitution. Both components share identical resistance value (270 kOhms), tolerance (±5%), power rating (0.05W), package dimensions (0201 / 0603 Metric), temperature coefficient (±250ppm/°C), and operating temperature range (-55°C ~ 125°C). PCB footprints are identical, and no design modifications are required.

Q: Are there differences in moisture sensitivity or handling requirements between these parts?

A: No. Both components carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity classification and handling requirements. No special moisture control measures are required for either component during storage or assembly.

Q: What is the significance of the different packaging formats (Tape & Reel vs. Cut Tape)?

A: Packaging format affects supply chain logistics and assembly process compatibility. Tape & Reel (TR) format is optimized for high-volume automated assembly lines with continuous feeder systems. Cut Tape (CT) & Digi-Reel® format provides flexibility for lower-volume applications or mixed-component assembly. Electrical and mechanical performance are identical; selection depends on manufacturing process requirements.

Q: Does the discontinued status of the MCR006YRTJ274 affect its electrical performance or reliability?

A: No. Discontinued status indicates distribution channel availability, not component performance or reliability. The electrical specifications, composition, and manufacturing technology remain unchanged. However, discontinued status may impact future procurement availability, requiring supply chain planning for long-term production requirements.

Q: Are the temperature coefficients and operating ranges truly identical?

A: Yes. Both components specify ±250ppm/°C temperature coefficient and -55°C ~ 125°C operating temperature range. These specifications are exact matches and ensure equivalent performance across the full operating environment.

Q: Can these components be used interchangeably in high-precision analog circuits?

A: Yes, within the tolerance specification. Both components carry ±5% tolerance classification. In applications requiring tighter tolerance control, component selection should be based on measured values rather than tolerance band alone. The identical temperature coefficient (±250ppm/°C) ensures equivalent drift characteristics across the operating temperature range.
