Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2152CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value of 21.5 kOhms, tolerance of ±1%, and power rating of 1W must be identical. Temperature coefficient of ±100ppm/°C ensures thermal stability equivalence.

Mechanical Compatibility: Package format must be 2512 (6432 Metric) to ensure PCB footprint compatibility. Physical dimensions (length, width, and maximum seated height) must accommodate existing board layouts without modification.

Environmental & Compliance Requirements: Operating temperature range of -55°C to 155°C must be maintained. RoHS3 compliance and MSL 1 rating are mandatory for equivalent substitution. REACH unaffected status ensures regulatory alignment.

Composition & Construction: Thick film construction is required to maintain electrical performance characteristics and reliability profiles equivalent to the original component.

The CRCW251221K5FKEG from Vishay Dale meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F2152CS and CRCW251221K5FKEG are active production components with identical electrical and mechanical specifications. Selection between these parts is based on availability, packaging format, and application-specific requirements.

The RC6432F2152CS features moisture-resistant thick film construction and is supplied in standard packaging. The CRCW251221K5FKEG is supplied in Tape & Reel (TR) format and carries AEC-Q200 automotive qualification. Both components maintain ROHS3 compliance and MSL 1 rating, confirming regulatory equivalence.

For applications requiring automotive-grade qualification, the CRCW251221K5FKEG provides AEC-Q200 certification. For general industrial applications, either component satisfies the specified electrical and environmental requirements. Packaging format selection (standard versus Tape & Reel) depends on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251221K5FKEG directly replace the RC6432F2152CS on existing PCBs?

A: Yes. Both components use the 2512 (6432 Metric) package with identical footprint requirements. Physical dimensions are equivalent within manufacturing tolerances, enabling direct PCB substitution without layout modification.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both components specify 21.5 kOhms ±1% resistance, 1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Electrical performance is equivalent.

Q: What is the difference between the packaging formats?

A: The RC6432F2152CS is supplied in standard packaging. The CRCW251221K5FKEG is supplied in Tape & Reel (TR) format, which is optimized for automated assembly processes and higher-volume production runs.

Q: Does the AEC-Q200 rating on the CRCW251221K5FKEG affect substitution eligibility?

A: No. AEC-Q200 is an additional qualification that does not prevent substitution in non-automotive applications. It indicates the component meets automotive reliability standards, making it suitable for both automotive and general industrial use.

Q: Are compliance certifications equivalent between these parts?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What factors should determine component selection between these two parts?

A: Selection is based on: (1) packaging format availability and assembly process compatibility, (2) inventory levels and lead time requirements, (3) application-specific qualification needs (automotive versus general industrial), and (4) cost considerations.
