Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC1005J2R7CS is based on the following criteria:

Primary Substitution Criteria (Identical Electrical Function):

• Resistance value: 2.7 Ohms
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Operating temperature range: -55°C to 155°C
• Composition: Thick Film
• RoHS3 compliance
• MSL 1 rating

Tolerance Grouping: Substitutes are organized by tolerance specification. The RC1005J2R7CS operates at ±5% tolerance. Upgrades to ±1% tolerance (RC1005F2R7CS, RMCF0402FT2R70) provide improved accuracy while maintaining all other electrical and mechanical parameters. The RMCF0402JT2R70 maintains ±5% tolerance matching the original specification.

Manufacturer Variants: Samsung Electro-Mechanics (RC series) and Stackpole Electronics Inc (RMCF series) both provide equivalent 2.7 Ohm 0402 resistors. Stackpole variants include AEC-Q200 automotive qualification with ±200ppm/°C temperature coefficient versus Samsung's ±300ppm/°C specification.

Packaging Consideration: The main part (RC1005J2R7CS) is supplied in Tape & Reel (TR) format. The RC1005F2R7CS substitute is available in Cut Tape (CT) format. Both packaging formats are compatible for component placement and assembly operations.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance): The RMCF0402JT2R70 provides direct electrical equivalence to the RC1005J2R7CS, maintaining ±5% tolerance and identical power rating within the 0402 package. Both components are ROHS3 compliant with MSL 1 rating. The Stackpole variant includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability standards.

Upgraded Tolerance Options: The RC1005F2R7CS and RMCF0402FT2R70 both offer ±1% tolerance, providing improved accuracy over the original ±5% specification. These upgrades maintain identical power rating, package dimensions, and operating temperature range. The RC1005F2R7CS remains within the Samsung Electro-Mechanics RC series, while the RMCF0402FT2R70 introduces Stackpole manufacturing with AEC-Q200 qualification and improved temperature coefficient (±200ppm/°C versus ±300ppm/°C).

Compliance and Certification: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard assembly and storage protocols. Stackpole variants carry AEC-Q200 automotive qualification, applicable to designs requiring automotive-grade component certification.

Inventory and Supply Considerations: Current inventory levels support component availability across all substitute options. Selection should prioritize tolerance requirements, manufacturer preference, and packaging format compatibility with existing assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC1005F2R7CS replace RC1005J2R7CS in existing designs?

A: Yes. The RC1005F2R7CS is electrically compatible as a direct substitute. Both components share identical resistance (2.7 Ohms), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). The primary difference is improved tolerance (±1% versus ±5%), which represents an upgrade in accuracy. Packaging format differs (Cut Tape versus Tape & Reel), but both formats are compatible with standard assembly equipment.

Q: What is the difference between Samsung RC series and Stackpole RMCF series?

A: Both manufacturers provide 2.7 Ohm 0402 resistors meeting the specified electrical requirements. Stackpole RMCF variants include AEC-Q200 automotive qualification and feature a lower temperature coefficient (±200ppm/°C) compared to Samsung RC series (±300ppm/°C). Selection depends on automotive qualification requirements and temperature stability specifications for the application.

Q: Is RMCF0402JT2R70 a direct replacement for RC1005J2R7CS?

A: Yes. The RMCF0402JT2R70 maintains identical tolerance (±5%), resistance (2.7 Ohms), power rating (0.063W), and package (0402). Both components operate across -55°C to 155°C and are ROHS3 compliant with MSL 1 rating. The Stackpole variant adds AEC-Q200 automotive qualification as an additional feature.

Q: Why would I choose a ±1% tolerance part over ±5%?

A: Tolerance selection depends on circuit accuracy requirements. ±1% tolerance (RC1005F2R7CS, RMCF0402FT2R70) provides tighter resistance value control, beneficial for precision analog circuits, measurement applications, or designs with tight impedance matching requirements. ±5% tolerance (RC1005J2R7CS, RMCF0402JT2R70) is suitable for general-purpose applications where component value variation within this range does not affect circuit performance.

Q: Are all substitute parts available in Tape & Reel packaging?

A: The RC1005J2R7CS, RMCF0402FT2R70, and RMCF0402JT2R70 are supplied in Tape & Reel (TR) format. The RC1005F2R7CS is available in Cut Tape (CT) format. Both packaging formats are compatible with automated assembly processes; format selection depends on production equipment and inventory management requirements.

Q: Do all parts meet RoHS3 compliance?

A: Yes. All listed parts (RC1005J2R7CS, RC1005F2R7CS, RMCF0402FT2R70, RMCF0402JT2R70) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting standard environmental and storage requirements for electronic component assembly.
