Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AC2010FK-07649RL are qualified based on the following criteria:

• Identical resistance value: 649 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.75W
• Same package designation: 2010 (5025 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C to 155°C
• Automotive compliance: AEC-Q200 certification
• Equivalent termination count: 2
• Matching RoHS and REACH compliance status

Physical dimensions (length, width, and seated height) remain within acceptable tolerances for PCB assembly compatibility. All substitute parts maintain the same electrical performance characteristics and environmental ratings as the primary part.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010649RFKEF (Vishay Dale) is the primary substitute for new designs. This part maintains active production status with identical electrical and mechanical specifications to the AC2010FK-07649RL. Both components carry AEC-Q200 automotive certification and ROHS3 compliance, ensuring compatibility in automotive applications requiring these standards.

ERJ-12SF6490U (Panasonic Electronic Components) is functionally equivalent but carries a "Not For New Designs" product status. This designation indicates the manufacturer is phasing out this part number. While the component meets all electrical and mechanical requirements, it should be used only for legacy system maintenance or replacement applications where the original part specification must be maintained.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010649RFKEF directly replace AC2010FK-07649RL in automotive applications?

A: Yes. Both parts are AEC-Q200 rated with identical resistance (649 Ohms ±1%), power rating (0.75W), package (2010), and operating temperature range (-55°C to 155°C). Physical dimensions are within acceptable assembly tolerances.

Q: Why is ERJ-12SF6490U marked "Not For New Designs"?

A: This designation reflects the manufacturer's product lifecycle status. The part remains functionally equivalent but is no longer recommended for new circuit designs. It is suitable for replacement or maintenance of existing systems.

Q: Are there any dimensional differences between these parts?

A: All three parts use the 2010 (5025 Metric) package. Seated height varies slightly: AC2010FK-07649RL at 0.026" (0.65mm), while CRCW2010649RFKEF and ERJ-12SF6490U are both 0.028" (0.70mm). These differences remain within standard PCB assembly tolerances.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive certification with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the primary reason to substitute these parts?

A: Substitution is typically driven by inventory availability, supply chain continuity, or cost optimization while maintaining identical electrical performance and automotive compliance standards.
