Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4750CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (475 Ohms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (2512 / 6432 Metric) and number of terminations (2) ensure physical fit and circuit board integration without redesign.

Compliance & Quality: RoHS3 compliance and MSL 1 rating confirm environmental and moisture handling standards. Product status (Active) indicates ongoing manufacturer support.

The identified substitute part CRCW2512475RFKEG from Vishay Dale meets all specified electrical and mechanical parameters while maintaining equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F4750CS and CRCW2512475RFKEG are Active product status components with ROHS3 compliance and MSL 1 ratings, confirming ongoing manufacturer support and environmental regulatory alignment. The electrical parameters—resistance, tolerance, power rating, and temperature coefficient—are identical across both parts, ensuring equivalent circuit performance. Mechanical dimensions are within acceptable tolerance for 2512 package placement, with maximum seated height differences of 0.002" (0.04mm) representing negligible variation for standard PCB assembly processes. The CRCW2512475RFKEG includes AEC-Q200 automotive qualification, providing additional quality assurance for applications requiring automotive-grade reliability. Selection between these parts depends on supply chain availability, packaging format requirements (Tape & Reel for Vishay versus standard packaging for Samsung), and application-specific quality certifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512475RFKEG directly replace RC6432F4750CS in existing designs?

A: Yes. Both components share identical electrical specifications (475 Ohms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C ~ 155°C), and use the 2512 (6432 Metric) package. Mechanical dimensions are within standard PCB assembly tolerances. No circuit redesign is required.

Q: What are the dimensional differences between these parts?

A: Width differs by 0.002" (0.15mm) and maximum seated height by 0.002" (0.04mm). These variations fall within standard PCB assembly specifications and do not affect circuit board layout or component placement.

Q: Are both parts RoHS compliant?

A: Yes. Both RC6432F4750CS and CRCW2512475RFKEG are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, confirming equivalent environmental and handling standards.

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

A: AEC-Q200 is an automotive industry quality standard. The CRCW2512475RFKEG carries this certification, indicating enhanced reliability testing and suitability for automotive applications. The Samsung part does not list this certification but remains suitable for general industrial and commercial applications.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Tape & Reel versus bulk) affects supply chain logistics and handling but does not impact electrical or mechanical compatibility. Component selection should consider manufacturing process requirements and inventory management practices.

Q: Are temperature coefficient and operating range identical?

A: Yes. Both parts specify ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating range, ensuring equivalent thermal performance across all operating conditions.
