Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F8660CS are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 866 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Equivalence Requirements:

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compliance Equivalence Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH status: REACH Unaffected

The CRCW2512866RFKEG from Vishay Dale meets all electrical, mechanical, and compliance criteria for direct substitution. The primary distinction is the inclusion of AEC-Q200 automotive qualification in the substitute part, which represents an additional certification level beyond the base requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F8660CS and CRCW2512866RFKEG are active production components with full ROHS3 compliance and REACH unaffected status. The electrical specifications are identical across resistance, tolerance, power rating, and temperature coefficient. Mechanical compatibility is confirmed through equivalent package format (2512) with minor dimensional variations within acceptable tolerances for PCB assembly.

The CRCW2512866RFKEG includes AEC-Q200 automotive qualification, which provides additional reliability documentation for applications requiring automotive-grade components. This certification does not restrict use in non-automotive applications and represents a superset of standard industrial requirements.

Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (Tape & Reel for CRCW2512866RFKEG)
• Automotive qualification necessity for the end application
• Supplier inventory and cost considerations

Frequently Asked Questions (FAQ)

Q: Can CRCW2512866RFKEG be used as a direct replacement for RC6432F8660CS?

A: Yes. Both components share identical electrical specifications (866 Ohms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C to 155°C), use thick film composition, and are packaged in the 2512 (6432 Metric) format. Mechanical dimensions are compatible within standard PCB assembly tolerances.

Q: What is the significance of AEC-Q200 qualification on the CRCW2512866RFKEG?

A: AEC-Q200 is an automotive industry standard qualification that documents component reliability under automotive operating conditions. This certification does not restrict the part to automotive applications and indicates a higher level of quality assurance documentation. Non-automotive applications may use this part without limitation.

Q: Are there packaging differences between these parts?

A: The RC6432F8660CS is supplied in standard packaging, while the CRCW2512866RFKEG is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes. Tape & Reel packaging is standard for high-volume production environments.

Q: Do these parts have identical moisture sensitivity levels?

A: Yes. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions and no special handling requirements during storage or assembly.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. They share identical regulatory status and may be used interchangeably in applications with these compliance requirements.

Q: What are the dimensional tolerances for PCB footprint design?

A: The RC6432F8660CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with maximum seated height of 0.026" (0.66mm). The CRCW2512866RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with maximum seated height of 0.028" (0.70mm). These minor variations are within standard PCB design tolerances for 2512 package footprints.
