• DC resistance: 500mOhm maximum (equal or lower)
• Current rating: minimum 600 mA (equal or higher)
• Shielding configuration: Unshielded (matching)
• Core material: Phenolic (matching)
• Operating temperature range: -55°C ~ 125°C (matching or exceeding)
• Mounting type: Through Hole Axial (matching)
• Physical dimensions: 0.156" Dia x 0.375" L (matching)
• Q factor and self-resonant frequency: 33 @ 7.9MHz and 160MHz (matching)

The 1537-16K from API Delevan Inc. meets all specified electrical and mechanical parameters, with a current rating of 670 mA, which exceeds the minimum requirement of 600 mA.

Parameter Comparison

Engineering Selection Recommendations

Both the 15M151K and 1537-16K are active products suitable for direct substitution in applications requiring 1.5 µH axial inductors. The 15M151K maintains RoHS compliance status as not applicable, while the 1537-16K is RoHS non-compliant. Both components are REACH unaffected and classified under ECCN EAR99 and HTSUS 8504.50.8000. Selection between these parts should be based on compliance requirements specific to the end application and regulatory jurisdiction. The 1537-16K offers a higher current rating of 670 mA compared to the 15M151K's 600 mA rating, providing additional design margin in current-limited applications.
