Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F621CS are classified based on strict alignment with the following critical parameters:

Electrical Specifications: Resistance value of 620 Ohms, tolerance of ±1%, and power rating of 1W must be identical across all substitutes.

Package Compatibility: All substitutes utilize the 2512 (6432 Metric) package format, ensuring mechanical fit and PCB footprint compatibility.

Environmental Performance: Temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C are maintained across all alternatives.

Regulatory Compliance: ROHS3 compliance and MSL 1 rating are required for all substitute candidates.

Composition: Thick film construction is consistent across the main part and all substitutes.

The RC2512FK-07620RL (YAGEO) qualifies as a direct manufacturer substitute with identical electrical and environmental specifications. The CRCW2512620RFKEG (Vishay Dale) qualifies as a similar substitute with additional automotive AEC-Q200 qualification, suitable for applications requiring enhanced reliability standards.

Parameter Comparison

Engineering Selection Recommendations

RC2512FK-07620RL (YAGEO): This substitute maintains complete electrical and environmental equivalence to the RC6432F621CS. Both components share identical resistance, tolerance, power rating, temperature coefficient, and operating range. ROHS3 compliance and MSL 1 rating are matched. The YAGEO part is available in Tape & Reel packaging format and carries active product status. Selection of this substitute is appropriate for standard applications where Samsung Electro-Mechanics sourcing is not mandated.

CRCW2512620RFKEG (Vishay Dale): This substitute meets all core electrical and environmental specifications of the RC6432F621CS while adding automotive AEC-Q200 qualification. The Vishay Dale component is suitable for applications requiring enhanced reliability validation or automotive-grade component certification. The additional AEC-Q200 rating does not compromise compatibility with non-automotive applications. This part is available in Tape & Reel packaging and maintains active product status.

Both substitutes are suitable for direct replacement based on electrical performance, mechanical compatibility, and regulatory compliance. Selection between substitutes depends on supply chain requirements, packaging preferences, and application-specific qualification needs.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07620RL replace RC6432F621CS in all applications?

A: Yes. The RC2512FK-07620RL maintains identical electrical specifications (620 Ohms ±1%, 1W), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and regulatory compliance (ROHS3, MSL 1). The 2512 package format is mechanically compatible. Substitution is valid for all applications where the original part is specified.

Q: What is the difference between the YAGEO and Vishay Dale substitutes?

A: Both parts meet the core specifications of the RC6432F621CS. The primary distinction is that CRCW2512620RFKEG includes automotive AEC-Q200 qualification, indicating enhanced reliability validation for automotive applications. Electrical and environmental performance are equivalent. The YAGEO part is suitable for general industrial applications, while the Vishay Dale part is qualified for automotive use.

Q: Are there packaging differences between these parts?

A: The RC6432F621CS is supplied in standard packaging. Both RC2512FK-07620RL and CRCW2512620RFKEG are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and automated assembly. If bulk or alternative packaging is required, consult supplier availability.

Q: Do dimensional variations affect PCB compatibility?

A: All three parts use the 2512 (6432 Metric) package with compatible footprints. Dimensional variations are within standard tolerance ranges: length 6.30-6.35mm, width 3.10-3.20mm, height 0.65-0.70mm. These variations do not affect PCB layout or assembly compatibility.

Q: Which substitute should be selected for new designs?

A: For new designs without automotive requirements, either RC2512FK-07620RL or CRCW2512620RFKEG is acceptable based on supply availability and cost. For automotive applications, CRCW2512620RFKEG is preferred due to AEC-Q200 qualification. Verify supplier inventory and lead times for production planning.

Q: Are all substitutes ROHS3 compliant?

A: Yes. RC6432F621CS, RC2512FK-07620RL, and CRCW2512620RFKEG are all ROHS3 compliant with MSL 1 rating. All parts are REACH unaffected and classified as EAR99 for export purposes.
