Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005J6R8CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 6.8 Ohms
• Tolerance: ±5%
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Temperature coefficient (within acceptable circuit performance margins)
• Manufacturer-specific features (e.g., automotive qualification)

The RMCF0402JT6R80 from Stackpole Electronics Inc qualifies as a direct substitute based on full alignment with all mandatory parameters. The substitute part features an improved temperature coefficient (±200ppm/°C versus ±300ppm/°C) and includes AEC-Q200 automotive qualification, providing enhanced performance characteristics without compromising electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can RMCF0402JT6R80 be used as a direct replacement for RC1005J6R8CS in existing designs?

A: Yes. Both parts share identical resistance (6.8 Ohms), tolerance (±5%), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). The RMCF0402JT6R80 features a superior temperature coefficient (±200ppm/°C versus ±300ppm/°C) and AEC-Q200 automotive qualification, making it a compatible upgrade without circuit redesign.

Q: What is the significance of the temperature coefficient difference?

A: The RC1005J6R8CS operates at ±300ppm/°C while the RMCF0402JT6R80 operates at ±200ppm/°C. This means the Stackpole part exhibits lower resistance drift across temperature variations, providing enhanced stability in temperature-sensitive applications. For most general-purpose circuits, both coefficients are acceptable; however, precision analog circuits benefit from the lower coefficient.

Q: Are both parts RoHS compliant?

A: Yes. Both RC1005J6R8CS and RMCF0402JT6R80 are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What does AEC-Q200 qualification mean for the RMCF0402JT6R80?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions, including thermal cycling, vibration, and humidity stress. This qualification is required for automotive applications but does not restrict use in non-automotive designs.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0402 (1005 Metric) format with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). They are footprint-compatible and require no PCB layout modifications.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures, simplifying logistics and inventory management.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, provided supply chain and cost considerations are evaluated. Both parts are Active status with established inventory levels (RC1005J6R8CS: 746 units; RMCF0402JT6R80: 19,541 units). The Stackpole part offers significantly higher availability, supporting high-volume production schedules.
