74404032100 Compatible Inductor Sourcing with Gujing GNR3015MT100

For buyers reviewing Würth Elektronik 74404032100, Gujing GNR3015MT100 provides a 10 µH candidate within the same listed 3 × 3 × 1.5 mm external envelope. The comparison lists matching current figures, with a DCR difference that your engineering team should assess during sample testing.

This pairing is relevant when a project needs a cost review or an additional supply option without starting from a larger component package. Our records describe both a cost-driven sample evaluation and a fire-protection equipment project. We can review your requirements and discuss the next sample and quotation steps.

GNR3015MT100 vs. 74404032100: 10 µH Specification Comparison

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.

Evaluating DCR and Temperature Rise in a 3 × 3 × 1.5 mm Package

The comparison aligns on nominal inductance, listed dimensions, 0.84 A saturation current and 0.87 A thermal current. These matches help narrow the initial candidate search for a space-limited design. Terminal geometry, assembly conditions and behavior under load still belong in the approval specification.

The listed DCR is 250 mΩ ±20% for Gujing and 230 mΩ ±20% for the reference. Where a compact enclosure leaves little cooling margin, the actual winding temperature can determine whether a quoted option is worthwhile. Give us the permissible temperature rise and operating current so the material or design discussion addresses the project’s real limit. Cost should be assessed after that limit is clear.

GNR3015MT100 Sourcing Cases: Sample and System Testing

A Beijing customer requested an option for 74404032100 in February 2022 because of project cost. Our record describes a price discussion followed by delivery of the specification and samples. The customer completed sample testing successfully, and small-batch trial validation was the planned next step when the record was prepared. It does not record completion of that later stage.

In January 2022, a Chongqing customer was selecting an inductor for fire-protection equipment. Gujing recommended GNR3015MT100, and the project entered complete-system testing. No problem had been reported at the recorded stage. For a new buyer, both examples show where technical support can help move a sourcing request forward, while keeping sample approval, trial production and complete-system approval as separate decisions.

Specification Review, Sample Testing and Production Approval

Selection and specification review

For this small 10 µH part, make the DCR tolerance, allowable temperature rise and land pattern explicit in the sample request. Use the customer’s system test to decide whether the standard specification is sufficient or a revised option should be discussed.

Samples and application feedback

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.

Trial production and order confirmation

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.

74404032100 Second-Source Evaluation: Frequently Asked Questions

Will the higher DCR prevent use in my design?

That depends on the current and thermal allowance in your circuit. Compare actual temperature rise and the resistance tolerance with your acceptance specification before making the sourcing decision.

Can I skip trial production after samples pass?

The recorded cost-review project planned a small-batch trial after successful sample tests. Your own approval route should define the checks needed for assembly, system operation and production release.

Is the fire-protection project evidence of certification?

It is an application record at a stated test stage. Share the standards, reports and qualification evidence required for your equipment so the supporting documentation for the exact part can be reviewed.

How are sample cost, MOQ and delivery confirmed?

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.
