Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS0603J113CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 11 kOhms (exact match required)
• Package / Case: 0201 (0603 Metric) (exact match required for PCB footprint compatibility)
• Power rating: 0.05W minimum (equal or higher acceptable)
• Composition: Thick Film (maintains electrical performance characteristics)

Acceptable Parameter Variations:

• Tolerance: ±5% or tighter (±1% tolerance is acceptable as it represents improved precision within the original specification range)
• Temperature coefficient: ±250ppm/°C or better (equal or lower variation acceptable)
• Operating temperature range: -55°C ~ 125°C or wider (equal or extended range acceptable)
• Regulatory compliance: ROHS3 Compliant (required for equivalent status)
• Moisture sensitivity: MSL 1 (Unlimited) or equivalent (required for handling compatibility)

Packaging Format Consideration: Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) without affecting electrical or mechanical compatibility, as both formats contain identical components.

Engineering Selection Recommendations

RC0603F113CS as Direct Substitute:

The RC0603F113CS meets all mandatory substitution criteria for the RCS0603J113CS. Both components are manufactured by Samsung Electro-Mechanics and share identical electrical specifications for resistance value, power rating, temperature coefficient, and operating temperature range. The substitute part features a tighter tolerance specification (±1% versus ±5%), which represents improved precision and remains fully compatible with circuit requirements.

Physical dimensions and package footprint are identical, ensuring direct PCB compatibility without layout modifications. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity classification, supporting equivalent handling and storage protocols.

The primary difference between these parts is the packaging format: the main part is supplied in Tape & Reel format while the substitute is supplied in Cut Tape format. This distinction affects procurement and assembly logistics but does not impact component performance or reliability.

Regulatory and Compliance Status:

Both the RCS0603J113CS and RC0603F113CS are active production components with full ROHS3 compliance and REACH unaffected status. Both parts carry EAR99 export classification and identical HTSUS commodity codes, supporting equivalent regulatory treatment in procurement and supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can RC0603F113CS replace RCS0603J113CS in existing designs?

A: Yes. The RC0603F113CS is electrically and mechanically compatible with the RCS0603J113CS. Both components have identical resistance values (11 kOhms), power ratings (0.05W), package dimensions (0201 / 0603 Metric), and operating temperature ranges (-55°C ~ 125°C). The substitute part's tighter tolerance (±1%) is compatible with circuit requirements specified for ±5% tolerance.

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

A: Tape & Reel (TR) and Cut Tape (CT) are different packaging and delivery formats for the same component. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging supplies components on shorter tape segments, suitable for lower-volume or manual assembly operations. The electrical and mechanical properties of the component itself are identical regardless of packaging format.

Q: Does the tighter tolerance of RC0603F113CS affect circuit performance?

A: No. The RC0603F113CS tolerance of ±1% is tighter than the RCS0603J113CS tolerance of ±5%, meaning the actual resistance value will be closer to the nominal 11 kOhms specification. This represents improved precision and is fully compatible with circuits designed for ±5% tolerance components. Tighter tolerance substitutes do not introduce compatibility issues.

Q: Are there any height differences between these parts?

A: The seated height specifications are nearly identical. The RCS0603J113CS has a maximum seated height of 0.010" (0.25mm), while the RC0603F113CS has a maximum seated height of 0.010" (0.26mm). This 0.01mm difference is negligible for PCB assembly and does not affect component placement or clearance requirements.

Q: Do both parts have the same environmental ratings?

A: Yes. Both the RCS0603J113CS and RC0603F113CS operate across the identical temperature range of -55°C ~ 125°C with the same temperature coefficient of ±250ppm/°C. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification, requiring identical handling and storage protocols.

Q: What is the inventory status for the substitute part?

A: The RC0603F113CS has 765 pieces available in inventory as new original stock. The main part RCS0603J113CS has 850 pieces available. Both parts are in active production status.
