Engineering Selection Recommendations

Selection between DC1390-334K and 1140-331K-RC is determined by product status (both active), inventory availability, and regulatory compliance designations. DC1390-334K is RoHS non-compliant; 1140-331K-RC is ROHS3 compliant. Both parts are REACH unaffected and have equivalent ECCN codes. Suitable substitution is supported strictly within these constraints.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting DC1390-334K?
A1: Substitution is based exclusively on matched inductance, tolerance, current rating, DC resistance, shielding, core material, mounting style, and package form factor.

Q2: Are there mechanical package differences between DC1390-334K and 1140-331K-RC?
A2: Both use radial, vertical cylinder packages with similar dimensions, though 1140-331K-RC is marginally larger in diameter and shorter in height.

Q3: How does RoHS compliance affect engineering selection?
A3: RoHS compliance is a mandatory requirement in many designs; 1140-331K-RC meets ROHS3 standards, while DC1390-334K does not.

Q4: Are there differences in maximum current or saturation current?
A4: 1140-331K-RC supports higher current and saturation ratings compared to DC1390-334K.

Q5: Is frequency or Q factor a substitution criterion here?
A5: No data is provided on Q or frequency parameters. Substitution is determined solely by listed electrical and mechanical attributes.

Q6: Does operating temperature differ?
A6: DC1390-334K supports up to 125°C. 1140-331K-RC is rated up to 105°C. Substitution should consider the required temperature range as specified.
