Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F39R2CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 39.2 Ohms
• Tolerance: ±1%
• Power Rating: 1W
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The CRCW251239R2FKEG manufactured by Vishay Dale satisfies all mandatory matching parameters. This substitute maintains identical electrical specifications and environmental ratings while offering Automotive AEC-Q200 certification and alternative packaging in Tape & Reel format. Physical dimensions remain within acceptable tolerances for direct board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F39R2CS and CRCW251239R2FKEG are Active status components with full ROHS3 compliance and REACH unaffected status, qualifying them for equivalent circuit applications. The RC6432F39R2CS provides moisture-resistant construction suitable for general industrial environments. The CRCW251239R2FKEG offers Automotive AEC-Q200 certification, making it appropriate for automotive and high-reliability applications requiring enhanced qualification standards. Selection between these components should be based on application-specific requirements: choose the Samsung component for standard industrial applications with moisture exposure concerns, or select the Vishay Dale component when automotive-grade reliability and qualification documentation are required. The Tape & Reel packaging of the CRCW251239R2FKEG supports high-volume automated assembly operations, while the standard packaging of the RC6432F39R2CS accommodates lower-volume or manual assembly workflows.
