Parameter Comparison

Engineering Selection Recommendations

Both the CRCW06034R53FNTC and RMCF0603FT4R53 are active production parts with identical electrical specifications and AEC-Q200 automotive qualification. The RMCF0603FT4R53 offers higher inventory availability (11,170 pieces versus 710 pieces) and ROHS3 compliance, making it suitable for applications with RoHS requirements. The CRCW06034R53FNTC remains the primary choice for designs with existing REACH Affected material declarations or where supplier continuity with Vishay Dale is mandated. Dimensional variations between the two parts are within typical PCB layout tolerances for 0603 package components.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603FT4R53 be used as a direct replacement for CRCW06034R53FNTC in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical parameters (4.53 Ohms ±1%, 0.1W, ±200ppm/°C, -55°C ~ 155°C operating range) and 0603 package specifications. Physical dimensions differ slightly but remain within standard PCB design tolerances for this package class.

Q: What is the difference in RoHS compliance between these parts?

A: The CRCW06034R53FNTC is RoHS non-compliant, while the RMCF0603FT4R53 is ROHS3 compliant. Selection depends on end-product regulatory requirements and material restriction directives applicable to the target market.

Q: Are there any height or footprint considerations when substituting these parts?

A: The RMCF0603FT4R53 has a maximum seated height of 0.022" (0.55mm) compared to 0.020" (0.50mm) for the CRCW06034R53FNTC. This 0.002" difference is negligible for standard PCB assembly processes. Dimensional variations in length and width (1.55mm x 0.80mm versus 1.60mm x 0.85mm) are within normal manufacturing tolerances for 0603 components.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. Identical electrical specifications, package designation, and AEC-Q200 qualification permit direct substitution in PCB designs. No circuit redesign or revalidation is required for the substitution.
