Key Parameters

Substitute Part Grouping Explanation

Substitution must be performed strictly where all core electrical and mechanical parameters match or are within the defined tolerances for the product category. Key substitution parameters include: inductance value, tolerance, current rating, DC resistance, material core type, shielding, mounting style, package dimensions, operating temperature range, RoHS/REACH compliance, and other regulatory status fields provided. Substitute parts must directly satisfy these matching criteria.

Engineering Selection Recommendations

The SWT-0.25-79 part status is obsolete. The SH150T-0.25-79 is currently marked active with matching RoHS3 and REACH compliance and identical international regulatory codes provided. Mechanical and electrical parameters conform to the originally specified attributes with only minor differences in package case style and seated height, as referenced. Selection adheres to direct regulatory compliance and status as provided in part documentation.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are required for replacing SWT-0.25-79?
A: Substitute parts are selected by matching inductance value, tolerance, current rating, DC resistance, core material, shielding, mounting type, package dimensions, operating temperature range, and compliance fields.

Q2: Is the SH150T-0.25-79 compatible as a direct replacement?
A: All specified electrical and mechanical parameters conform to those listed for SWT-0.25-79. Package style differences are defined in the data, with dimensions matched.

Q3: Are there any differences in regulatory compliance between the main and substitute parts?
A: Both parts are listed as ROHS3 Compliant, REACH Unaffected, ECCN EAR99, and HTSUS 8504.50.4000.

Q4: What package and mounting considerations should be noted?
A: The main part uses a radial, horizontal (open) case, while the substitute features radial, horizontal - corner terminals. Both maintain through-hole mounting and identical footprint dimensions; seated height varies minimally within provided parameter limits.

Q5: Does the substitute affect operating temperature range or test frequency?
A: Both components specify an operating temperature range of -40°C ~ 125°C and a test frequency of 10 kHz.
