Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F4534CS are identified based on the following critical parameters that determine functional equivalence:

Electrical Parameters:

• Resistance value: 4.53 MOhms (exact match required)
• Tolerance: ±1% (ensures precision matching)
• Power rating: 0.25W / 1/4W (thermal capability)
• Temperature coefficient: ±100ppm/°C (stability specification)
• Operating temperature range: -55°C to 155°C (environmental limits)

Mechanical Parameters:

• Package format: 1206 (3216 Metric) (PCB footprint compatibility)
• Composition: Thick Film (material consistency)
• Number of terminations: 2 (standard configuration)

Compliance Parameters:

• RoHS3 compliance (regulatory requirement)
• Moisture sensitivity level: 1 (handling and storage compatibility)

The CRCW12064M53FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute. Additional differentiation includes automotive AEC-Q200 qualification on the Vishay part, which provides enhanced reliability for automotive applications while maintaining full compatibility with standard industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC3216F4534CS and CRCW12064M53FKEA are active production components with full ROHS3 compliance and identical electrical specifications. Selection between these parts is based on application requirements and supply chain considerations:

RC3216F4534CS (Samsung Electro-Mechanics): Select this part for standard industrial applications where moisture-resistant thick film composition and unlimited MSL rating are required. The part is suitable for general-purpose high-impedance circuits operating within the -55°C to 155°C temperature range.

CRCW12064M53FKEA (Vishay Dale): Select this part for automotive applications or where AEC-Q200 qualification is specified. The Vishay part provides enhanced reliability documentation and automotive-grade qualification while maintaining full compatibility with all electrical and mechanical parameters of the Samsung equivalent. The marginally lower seated height (0.024" vs 0.026") presents no compatibility issues for standard PCB designs.

Both parts are suitable for direct substitution in existing designs without circuit modification or re-qualification, provided application requirements do not mandate automotive-specific certifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12064M53FKEA directly replace RC3216F4534CS in existing designs?

A: Yes. Both parts share identical electrical specifications (4.53 MOhms ±1%, 0.25W, ±100ppm/°C), identical package dimensions (1206 / 3216 Metric), and identical operating temperature range (-55°C to 155°C). The 0.002" difference in seated height (0.024" vs 0.026") does not affect PCB assembly compatibility. No circuit modification or design re-qualification is required.

Q: What is the significance of AEC-Q200 qualification on the Vishay part?

A: AEC-Q200 is an automotive industry standard qualification that documents enhanced reliability testing and quality assurance. This certification is required for automotive applications but provides no functional difference for standard industrial use. The Vishay part is suitable for both automotive and non-automotive applications.

Q: Are there any moisture sensitivity or storage differences between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and storage requirements. No special handling or baking procedures are required for either part prior to assembly.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both RC3216F4534CS and CRCW12064M53FKEA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.

Q: What is the basis for substitution between these two parts?

A: Substitution is based on matching all critical electrical parameters (resistance value, tolerance, power rating, temperature coefficient, operating temperature range), identical package format (1206), identical composition (thick film), and equivalent compliance certifications (ROHS3, MSL 1). These parameters ensure functional and mechanical interchangeability in circuit applications.
