Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F2492CS are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 24.9 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Number of terminations: 2 (exact match required)

Acceptable Variation Parameters:

• Packaging format (Bulk vs. Tape & Reel)
• Manufacturer and series designation
• Specific feature sets (e.g., Automotive AEC-Q200 qualification)
• RoHS and REACH compliance status
• Physical dimensions within tolerance (height and width variations ≤0.002")

The identified substitutes CRCW251224K9FKEG and CRCW251224K9FKTG from Vishay Dale meet all critical electrical and mechanical parameters. Both are supplied in Tape & Reel packaging and feature Automotive AEC-Q200 qualification, distinguishing them from the original Samsung component.

Parameter Comparison

Engineering Selection Recommendations

CRCW251224K9FKEG (Vishay Dale) - Primary Substitute:

This part is the preferred substitute for the RC6432F2492CS. It matches all critical electrical parameters and maintains identical operating temperature range and moisture sensitivity classification. The component is ROHS3 compliant and REACH unaffected, aligning with the regulatory status of the original part. The Automotive AEC-Q200 qualification provides additional reliability assurance for demanding applications. Physical dimensions vary minimally (width 3.15mm vs. 3.20mm; height 0.70mm vs. 0.66mm), remaining within acceptable PCB layout tolerances for 2512 package footprints. Tape & Reel packaging supports automated assembly processes.

CRCW251224K9FKTG (Vishay Dale) - Secondary Substitute:

This part provides electrical and mechanical equivalence to the RC6432F2492CS with identical resistance, tolerance, power rating, and thermal characteristics. However, it carries RoHS non-compliance and REACH-affected status, making it unsuitable for applications requiring regulatory compliance with current environmental directives. Selection of this part requires explicit design approval and documented compliance justification. Physical dimensions match CRCW251224K9FKEG. Tape & Reel packaging format applies.

Selection Criteria:

• For RoHS3-compliant and REACH-unaffected applications: select CRCW251224K9FKEG
• For legacy or non-regulated applications where RoHS non-compliance is acceptable: CRCW251224K9FKTG is electrically equivalent
• For bulk packaging requirements: retain RC6432F2492CS or request Vishay parts in alternative packaging

Frequently Asked Questions (FAQ)

Q: Can CRCW251224K9FKEG be used as a direct replacement for RC6432F2492CS on existing PCBs?

A: Yes. Both components use the 2512 (6432 Metric) package with identical footprint requirements. Physical dimension variations (width 3.15mm vs. 3.20mm; height 0.70mm vs. 0.66mm) fall within standard PCB design tolerances for this package class. No layout modifications are required.

Q: What is the difference between CRCW251224K9FKEG and CRCW251224K9FKTG?

A: Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, and thermal specifications. The primary differences are regulatory compliance: CRCW251224K9FKEG is ROHS3 compliant and REACH unaffected, while CRCW251224K9FKTG is RoHS non-compliant and REACH affected. Selection depends on application regulatory requirements.

Q: Are the Vishay substitutes qualified for automotive applications?

A: Both Vishay parts carry Automotive AEC-Q200 qualification, indicating suitability for automotive-grade reliability standards. The original Samsung RC6432F2492CS does not specify AEC-Q200 qualification.

Q: Does the packaging format (Bulk vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical and thermal performance remain identical regardless of packaging configuration.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 indicates the component requires no special moisture control during storage or handling. All three parts (RC6432F2492CS, CRCW251224K9FKEG, CRCW251224K9FKTG) share this classification, eliminating moisture-related compatibility concerns.

Q: Can these parts be intermixed in the same production batch?

A: Yes, provided regulatory compliance requirements are uniform across the application. If RoHS3 compliance is mandatory, use only RC6432F2492CS or CRCW251224K9FKEG. CRCW251224K9FKTG must not be mixed with compliant parts in regulated applications.

Q: What is the temperature coefficient significance for substitution?

A: All three parts share ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating range. This ensures equivalent temperature stability and thermal performance across the full operating envelope. No temperature-related derating adjustments are required when substituting between these parts.
