Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 744902127 are qualified based on the following critical parameters:

• Inductance Value: 27 nH (exact match required)
• Current Rating: 250 mA minimum
• Package Format: 0603 (1608 Metric) surface mount
• DC Resistance: Maximum 2.35 Ohm (within acceptable operational tolerance)
• Environmental Compliance: ROHS3 compliant, MSL 1 rating
• Physical Dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm), Height 0.022" (0.55mm) maximum

The identified substitute parts meet these core electrical and mechanical specifications, enabling direct replacement in circuit designs where the 744902127 is specified.

Parameter Comparison

Engineering Selection Recommendations

Abracon LLC ATFC-0603-27N-FT: This substitute maintains identical inductance, current rating, and physical dimensions. The DC resistance specification of 2.35 Ohm Max represents a 0.35 Ohm increase from the original part. The operating temperature range is reduced to -25°C ~ 85°C compared to the original -40°C ~ 125°C specification. ROHS3 compliance and MSL 1 rating are maintained. This part is suitable for applications where the reduced temperature range is acceptable.

Stackpole Electronics LTF0603GT27N: This substitute provides the same 27 nH inductance value in 0603 package format with active product status, ensuring long-term availability. Complete electrical parameter specifications are not provided in the available data. Selection of this part requires verification that unspecified parameters meet circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the Abracon ATFC-0603-27N-FT be used as a direct replacement for the Würth Elektronik 744902127?

A: The Abracon part matches the inductance value, current rating, and physical package dimensions. The DC resistance increases from 2 Ohm Max to 2.35 Ohm Max, and the operating temperature range narrows from -40°C ~ 125°C to -25°C ~ 85°C. Direct replacement is possible if these parameter differences are acceptable for the application.

Q: What is the primary difference between the substitute parts?

A: The Abracon ATFC-0603-27N-FT is also classified as obsolete but provides complete electrical specifications matching the original part within tolerance. The Stackpole LTF0603GT27N has active product status, ensuring future availability, but complete electrical parameter data is not available.

Q: Are all substitute parts ROHS3 compliant?

A: The Abracon ATFC-0603-27N-FT is confirmed ROHS3 compliant with MSL 1 rating. Compliance status for the Stackpole part is not specified in the available data.

Q: Does the 0603 package format remain consistent across all parts?

A: Yes. All parts use the 0603 (1608 Metric) surface mount package with identical physical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm).

Q: What should be considered when selecting between substitute options?

A: Selection depends on application-specific requirements: temperature range requirements, DC resistance tolerance, long-term availability needs, and compliance certifications. The Abracon part provides complete specification alignment with minor parameter variations. The Stackpole part offers active status but requires verification of unspecified electrical parameters.
