Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F8250CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (825 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 format must be 2512 (6432 Metric) to ensure PCB footprint compatibility. Physical dimensions and termination count (2 terminations) must match or fall within acceptable assembly tolerances.

Composition & Construction: Thick film construction is required to maintain electrical and thermal characteristics equivalent to the original part.

Compliance & Certification: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are baseline requirements. Additional certifications such as AEC-Q200 do not disqualify a substitute but indicate enhanced qualification for specific applications.

The CRCW2512825RFKEG from Vishay Dale meets all substitution criteria through identical electrical and mechanical specifications while adding automotive-grade AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F8250CS and CRCW2512825RFKEG are Active products with full RoHS3 compliance and identical core electrical and mechanical specifications. Selection between these parts should be based on:

Availability: The CRCW2512825RFKEG maintains higher inventory (4477 units) compared to the RC6432F8250CS (645 units), providing supply chain flexibility.

Application Requirements: The CRCW2512825RFKEG carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. The RC6432F8250CS with moisture-resistant thick film construction serves general-purpose industrial applications.

Packaging Format: The RC6432F8250CS is supplied in standard packaging, while the CRCW2512825RFKEG is available in Tape & Reel (TR) format, which may influence procurement and assembly processes.

Both parts satisfy identical electrical performance criteria and thermal operating ranges, ensuring functional equivalence in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512825RFKEG directly replace the RC6432F8250CS in existing designs?

A: Yes. Both parts share identical resistance (825 Ohms), tolerance (±1%), power rating (1W), package format (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). PCB footprints and electrical performance are equivalent.

Q: What is the significance of AEC-Q200 qualification on the CRCW2512825RFKEG?

A: AEC-Q200 is an automotive industry standard qualification indicating enhanced reliability testing and quality assurance. This certification does not alter the electrical or mechanical specifications but confirms suitability for automotive applications. Non-automotive applications are unaffected by this certification.

Q: Are there dimensional differences between these parts?

A: Dimensions are functionally equivalent. The RC6432F8250CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max height. The CRCW2512825RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" max height. These minor variations fall within standard PCB assembly tolerances for the 2512 package.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both the RC6432F8250CS and CRCW2512825RFKEG carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Which part should be selected for new designs?

A: Selection depends on application context and supply chain strategy. For automotive or high-reliability applications, the CRCW2512825RFKEG with AEC-Q200 qualification is appropriate. For general-purpose industrial applications, either part is suitable. Inventory availability and packaging requirements (Tape & Reel vs. standard) may also influence selection.
