Frequently Asked Questions (FAQ)

Q: Can CRGCQ2010F18K be used as a direct replacement for AC2010FK-0718KL?

A: Yes. Both parts share identical resistance (18 kOhms), tolerance (±1%), power rating (0.75W), package format (2010), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Physical dimensions and termination count are identical.

Q: Are there any differences in compliance or certifications?

A: Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited). The AC2010FK-0718KL has confirmed REACH Unaffected status, while the CRGCQ2010F18K shows Vendor Undefined REACH status. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: What determines substitution eligibility for 2010 package resistors?

A: Substitution eligibility is determined by matching resistance value, tolerance, power rating, package dimensions, composition type, temperature coefficient, operating temperature range, and automotive certifications. All these parameters must align for functional equivalence.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical package format (2010/5025 Metric), physical dimensions (0.197" L x 0.098" W, 0.026" height maximum), and two-termination configuration ensure mechanical and electrical interchangeability in PCB layouts designed for either part.
