Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS0603J623CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 62 kOhms
• Package / Case: 0201 (0603 Metric)
• Power rating: 0.05W (1/20W)
• Composition: Thick Film
• Temperature coefficient: ±250ppm/°C
• Operating temperature range: -55°C ~ 125°C
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±5%
• Packaging format: May differ (Tape & Reel vs. Cut Tape)
• Feature set: May include subset or superset of features (Anti-Sulfur optional)

The RC0603F623CS qualifies as a substitute because it maintains all mandatory parameters while offering improved tolerance (±1% vs. ±5%) and alternative packaging (Cut Tape vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RCS0603J623CS): Select the RCS0603J623CS when procurement specifications explicitly require Tape & Reel packaging format or when the ±5% tolerance specification is the design requirement. This part maintains Active product status and ROHS3 compliance.

Substitute Part Selection (RC0603F623CS): The RC0603F623CS is suitable for applications where tighter tolerance (±1%) is acceptable or beneficial. This substitute offers higher inventory availability (1914 units vs. 793 units) and maintains identical electrical performance across all critical parameters. The Cut Tape packaging format is compatible with standard pick-and-place assembly processes. Both parts are ROHS3 Compliant and REACH Unaffected, ensuring regulatory compliance in equivalent measure.

Compliance Basis: Both parts satisfy ROHS3 Compliant and REACH Unaffected requirements. Selection between them should be based on packaging format requirements and tolerance specifications for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can RC0603F623CS replace RCS0603J623CS in all applications?

A: RC0603F623CS is electrically compatible with RCS0603J623CS for applications where ±1% tolerance meets or exceeds the design requirement. Both parts share identical resistance value, power rating, package dimensions, temperature coefficient, and operating temperature range. Packaging format differs (Cut Tape vs. Tape & Reel), which may affect assembly process compatibility but not electrical performance.

Q: What is the tolerance difference between these parts?

A: RCS0603J623CS specifies ±5% tolerance, while RC0603F623CS specifies ±1% tolerance. The ±1% tolerance of the substitute part is tighter, meaning the actual resistance value will be closer to the nominal 62 kOhms specification. This represents an improvement in precision and is compatible with designs requiring ±5% tolerance.

Q: Are the physical dimensions identical?

A: Both parts use the 0201 (0603 Metric) package with identical length and width dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm). Maximum seated height differs slightly: RCS0603J623CS is 0.010" (0.25mm) while RC0603F623CS is 0.010" (0.26mm). This 0.01mm difference is negligible for standard PCB assembly applications.

Q: What packaging format difference exists between these parts?

A: RCS0603J623CS is supplied in Tape & Reel (TR) format, while RC0603F623CS is supplied in Cut Tape (CT) format. Tape & Reel packaging is optimized for high-volume automated assembly, while Cut Tape is suitable for lower-volume or mixed-component assembly processes. Both formats are compatible with standard SMD assembly equipment.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RCS0603J623CS and RC0603F623CS are ROHS3 Compliant and REACH Unaffected. They share identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications and both maintain Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should be selected for new designs?

A: For new designs, RC0603F623CS is recommended due to higher inventory availability (1914 units vs. 793 units) and superior tolerance specification (±1%). The tighter tolerance provides better circuit performance without compromising compatibility. Select RCS0603J623CS only when Tape & Reel packaging is a mandatory requirement or when ±5% tolerance is the explicit design specification.
