Substitute Part Grouping Explanation

The CRCW1206680RFKEAHP qualifies as a direct substitute based on the following allowed parameters:

Matching electrical characteristics: Both parts maintain 680 Ohm nominal resistance value and identical operating temperature range (-55°C to 155°C). Both employ thick film composition technology and share the same temperature coefficient specification of ±100ppm/°C.

Package compatibility: Both components use the 1206 (3216 Metric) package format with identical footprint dimensions (0.122" L x 0.061-0.063" W) and maximum seated height of 0.026" (0.65mm), ensuring mechanical interchangeability on printed circuit boards.

Automotive compliance: Both parts carry AEC-Q200 automotive qualification and pulse withstanding capability, meeting the same reliability and performance standards required for automotive applications.

Enhanced specifications: The substitute part offers improved tolerance (±1% versus ±10%) and increased power rating (0.75W versus 0.333W), providing superior performance margins without compromising compatibility.

Regulatory alignment: Both parts maintain ROHS3 compliance, MSL 1 rating, and identical ECCN/HTSUS classifications, ensuring no supply chain or regulatory complications.

Parameter Comparison

Engineering Selection Recommendations

The CRCW1206680RFKEAHP from Vishay Dale is a qualified substitute for the RPC1206KT680R. Both components maintain active product status and carry identical automotive AEC-Q200 certification. The substitute part meets all mechanical and electrical compatibility requirements within the 1206 package class.

Selection between these parts should be based on application-specific requirements. The RPC1206KT680R remains appropriate for designs where the 0.333W power rating and ±10% tolerance are sufficient. The CRCW1206680RFKEAHP is suitable for applications requiring improved tolerance performance (±1%) or higher power dissipation capability (0.75W), while maintaining full compatibility with existing PCB layouts and automotive compliance frameworks.

Both parts comply with ROHS3 regulations and carry unlimited moisture sensitivity ratings, eliminating supply chain or handling constraints. Inventory availability favors the Vishay Dale component with 27436 units in stock compared to 1031 units for the Stackpole part.

Frequently Asked Questions (FAQ)

Q: Can the CRCW1206680RFKEAHP be used as a direct replacement for the RPC1206KT680R on existing PCBs?

A: Yes. Both components use identical 1206 (3216 Metric) package dimensions with matching footprint requirements. No PCB layout modifications are necessary for substitution.

Q: What is the significance of the tolerance difference between ±10% and ±1%?

A: Tolerance defines the acceptable resistance value range from nominal. The RPC1206KT680R allows 612-748 Ohms, while the CRCW1206680RFKEAHP allows 673-687 Ohms. Applications requiring tighter resistance control benefit from the ±1% specification.

Q: Does the higher power rating of the CRCW1206680RFKEAHP affect circuit performance?

A: No. Power rating indicates maximum dissipation capability. A component rated for 0.75W can safely operate in circuits designed for 0.333W dissipation. The higher rating provides additional thermal margin without changing electrical behavior.

Q: Are both parts suitable for automotive applications?

A: Yes. Both components carry AEC-Q200 automotive qualification and pulse withstanding capability, meeting automotive reliability and performance standards.

Q: What is the impact of MSL 1 rating on component handling?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. Both components can be stored and handled without special moisture control measures or baking requirements prior to assembly.

Q: Do these parts have identical temperature performance?

A: Yes. Both components operate across -55°C to 155°C with identical temperature coefficient of ±100ppm/°C, ensuring equivalent thermal stability across the operating range.
