Engineering Selection Recommendations
CRCW2512187RFKEG (Vishay Dale) qualifies as a direct substitute for RC6432F1870CS. Both components share identical electrical specifications, package format, and environmental operating parameters. The Vishay Dale part carries AEC-Q200 automotive qualification, which represents an additional compliance certification beyond the base requirements. Both parts maintain active production status and ROHS3 compliance. Selection between these parts may be determined by supply chain availability, packaging format preference (Cut Tape & Digi-Reel versus standard packaging), or specific application requirements for automotive-grade qualification.
Frequently Asked Questions (FAQ)
Q: Can CRCW2512187RFKEG replace RC6432F1870CS in existing designs?
A: Yes. Both parts share identical resistance (187 Ohms), tolerance (±1%), power rating (1W), package format (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The physical footprint and electrical performance are equivalent.
Q: What is the difference between these two parts?
A: The primary difference is manufacturer and additional certification. CRCW2512187RFKEG carries AEC-Q200 automotive qualification, while RC6432F1870CS features moisture-resistant thick film construction. Both meet ROHS3 and MSL 1 requirements. Packaging format differs: Vishay Dale offers Cut Tape & Digi-Reel options.
Q: Are the physical dimensions identical?
A: Dimensions are functionally equivalent. RC6432F1870CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max height. CRCW2512187RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" max height. Both fit the 2512 package footprint standard.
Q: Which part should be selected for new designs?
A: Selection depends on application requirements. For automotive applications, CRCW2512187RFKEG with AEC-Q200 qualification is appropriate. For general industrial applications, either part meets specifications. Verify supply chain availability and packaging requirements for your manufacturing process.
Q: Are both parts RoHS compliant?
A: Yes. Both RC6432F1870CS and CRCW2512187RFKEG are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
