Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2052CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (20.5 kOhms), 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 remain within acceptable assembly tolerances.

Composition & Construction: Thick film construction is the specified technology. Moisture resistance characteristics and MSL 1 rating ensure reliability in standard storage and assembly environments.

Compliance & Certifications: ROHS3 compliance and REACH unaffected status are mandatory for regulatory alignment. Additional certifications such as AEC-Q200 do not disqualify a substitute but indicate enhanced qualification for specific applications.

The CRCW251220K5FKEG from Vishay Dale meets all substitution criteria through identical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F2052CS and CRCW251220K5FKEG are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability, supply chain requirements, and application-specific certifications.

The RC6432F2052CS features moisture-resistant thick film construction with MSL 1 rating, suitable for standard industrial and commercial applications. The CRCW251220K5FKEG carries AEC-Q200 automotive qualification, indicating enhanced reliability testing and suitability for automotive-grade applications where such certification is required.

Both components share identical electrical performance, thermal characteristics, and mechanical compatibility. The choice between manufacturers depends on procurement strategy, inventory availability, and whether automotive-grade qualification is a system requirement.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251220K5FKEG replace the RC6432F2052CS in any application?

A: Yes. Both parts share identical resistance (20.5 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 2512 package format. Electrical and mechanical compatibility is complete.

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

A: AEC-Q200 indicates the component has undergone automotive-grade reliability testing and qualification. This certification is required for automotive applications but does not affect compatibility with non-automotive designs. The Samsung part lacks this certification but remains suitable for general industrial and commercial use.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within acceptable tolerances. The RC6432F2052CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max seated height. The CRCW251220K5FKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" max seated height. Both fit the 2512 (6432 Metric) footprint and are PCB-compatible.

Q: What packaging formats are available?

A: The RC6432F2052CS is supplied in standard packaging. The CRCW251220K5FKEG is available in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, meeting standard industrial temperature requirements. Thermal performance is equivalent.
