If a supply or cost review has led you to search for a Würth Elektronik 74404064010 option, Gujing GNR6045NT1R0 offers a 1.0 µH candidate with the same listed 6 × 6 × 4.5 mm external dimensions. The key selection question is the circuit’s continuous-current requirement, because the thermal-current figures differ.
Our project record includes a household-appliance customer that tested Gujing samples and continued purchasing after evaluation. We can discuss your current waveform, cooling conditions and delivery target to establish whether this standard model deserves sample testing or another specification should be reviewed.

Comparison figures are from Gujing’s technical proposal. Confirm the current approved specifications and test conditions when agreeing sample acceptance.
Discuss this pairing with our team and request the proposed specification, sample arrangements and a quotation.
Both parts are listed at 11 A for saturation current under the comparison’s stated condition. That does not make 11 A the continuous operating rating. GNR6045NT1R0 is listed at 4.2 A thermal current, compared with 5.14 A for the reference. Its DCR is 18.2 mΩ maximum, while the reference is listed at 11 mΩ ±30%.
For procurement, this distinction prevents an apparent part-number match from becoming an unsuitable purchase. If the circuit’s RMS current and cooling conditions fit the proposed part, it may be worth evaluating as an additional source. If thermal margin is already limited, share that constraint early so our team can discuss material or design options before a sample order is agreed.
In June 2020, a Beijing customer asked Gujing for a 74404064010 sourcing option for a household-appliance application. Our engineering team matched GNR6045NT1R0 and provided samples for trial use. The project record states that the customer completed testing, accepted the candidate for the application and continued purchasing from Gujing afterward.
Another inquiry, from a Jiangxi customer in May 2020, was prompted by the original supplier’s long delivery period. The historical record discussed a delivery option for this Gujing model. For a new order, the relevant next step is to confirm the current production schedule against the exact specification and quantity. A past delivery quotation is not a standing commitment for today’s order.
For this pairing, provide RMS current, peak current, ripple and ambient temperature separately. The sample comparison should establish both inductance behavior at peaks and winding temperature during sustained operation.
Discuss sample quantities and the tests needed for your circuit. Share measured temperature rise, electrical results or application issues with our technical team so we can review the candidate and, where appropriate, discuss material or design adjustments.
Before production release, agree the specification, drawing and approved sample with your team. Confirm packaging, inspection requirements, order quantity and delivery schedule in the commercial discussion. A second-source evaluation can then progress through your own approval process.
The 11 A figure is the listed saturation-current value, not the thermal-current value. Review the 4.2 A thermal figure and your actual waveform and cooling conditions with engineering before selecting an operating point.
State the required continuous current and allowable temperature rise in the inquiry. We can review whether another standard option or a material or design adjustment is more appropriate than this listed candidate.
Share the exact specification, quantity and required date. Request the current sample and production schedule in the quotation so procurement can assess timing alongside engineering approval.
They are confirmed for the agreed specification, sample or order quantity and packaging requirements. Include your target delivery date when requesting a quotation; historical case schedules are not current order commitments.
Send the 74404064010 datasheet, RMS and peak current, operating frequency, ambient temperature, available cooling and PCB footprint. Add the required quantity and delivery date. We can discuss the suitability of GNR6045NT1R0, possible specification adjustments, samples and a current quotation.
