Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F432CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 4.3 kOhms (exact match required)
• Tolerance: ±1% (precision grade equivalence)
• Power Rating: 0.05W / 1/20W (thermal capacity match)
• Package / Case: 0201 (0603 Metric) (physical and electrical footprint compatibility)
• Composition: Thick Film (manufacturing process equivalence)
• Number of Terminations: 2 (terminal configuration)

Compliance Parameters:

• RoHS3 Compliant status (regulatory requirement)
• MSL 1 rating (moisture handling compatibility)

Allowable Variations:

• Operating Temperature Range: Substitute parts with extended upper temperature limits (155°C vs. 125°C) are acceptable as they provide enhanced thermal performance
• Temperature Coefficient: Variations within industry-standard ranges (±100ppm/°C to ±250ppm/°C) are acceptable for general applications
• Manufacturer identity: Different manufacturers producing equivalent specifications are acceptable

The CRCW02014K30FKED from Vishay Dale meets all mandatory matching parameters and compliance requirements, establishing it as a direct electrical and mechanical equivalent.

Engineering Selection Recommendations

Primary Selection (RC0603F432CS - Samsung Electro-Mechanics): Select the RC0603F432CS when Samsung Electro-Mechanics supply chain preference, existing inventory, or established vendor relationships are prioritized. This component carries Active product status with full RoHS3 compliance and MSL 1 rating, confirming long-term availability and regulatory support.

Substitute Selection (CRCW02014K30FKED - Vishay Dale): Select the CRCW02014K30FKED when supply chain diversification, extended operating temperature performance (-55°C to 155°C vs. -55°C to 125°C), or improved temperature coefficient stability (±100ppm/°C vs. ±250ppm/°C) are required. This component maintains identical electrical specifications, physical dimensions, and regulatory compliance status. The CRCW02014K30FKED is suitable for applications demanding enhanced thermal performance or requiring alternative sourcing channels.

Compliance Verification: Both components satisfy RoHS3 compliance, REACH unaffected status, and EAR99 export classification. MSL 1 rating on both parts eliminates moisture sensitivity constraints during handling and storage.

Frequently Asked Questions (FAQ)

Q: Can CRCW02014K30FKED replace RC0603F432CS in existing designs without PCB modification?

A: Yes. Both components share identical package specifications (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W, 0.26mm max height), and electrical ratings (4.3 kOhms ±1%, 0.05W). Direct PCB footprint compatibility is confirmed. No layout changes are required.

Q: What is the significance of the temperature coefficient difference (±250ppm/°C vs. ±100ppm/°C)?

A: Temperature coefficient defines resistance value drift across the operating temperature range. The CRCW02014K30FKED exhibits lower drift (±100ppm/°C), resulting in more stable resistance values across temperature extremes. For applications with tight tolerance requirements or wide temperature operation, the Vishay component provides superior performance. For standard applications, both coefficients are within acceptable industrial ranges.

Q: Are there any moisture handling differences between these components?

A: No. Both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints. Standard handling procedures apply to both parts without differential precautions.

Q: Why does the CRCW02014K30FKED support higher maximum operating temperature (155°C vs. 125°C)?

A: The extended temperature rating reflects Vishay Dale's component design and qualification testing. This provides design margin for applications operating near thermal limits or experiencing localized heating. The RC0603F432CS remains suitable for applications within its -55°C to 125°C envelope.

Q: Are both components suitable for high-reliability applications?

A: Both components carry Active product status and full RoHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. Selection between them should be based on specific application requirements (temperature range, supply chain preference, inventory availability) rather than reliability differentiation.

Q: What packaging format is supplied for both components?

A: Both RC0603F432CS and CRCW02014K30FKED are supplied in Tape & Reel (TR) format, standard for automated PCB assembly processes.
