• Operating temperature range: -55°C to 125°C
• Mounting type: Through hole axial configuration
• Physical dimensions: 0.156" Dia x 0.375" L (3.96mm x 9.53mm)
• Q factor and self-resonant frequency characteristics

The 1537-12K from API Delevan Inc. meets all specified electrical parameters and mechanical requirements, making it a direct functional equivalent for the 15M101K.

Parameter Comparison

Engineering Selection Recommendations

The 1537-12K qualifies as a functional equivalent to the 15M101K based on matching electrical specifications and identical physical dimensions. The 1537-12K provides a higher current rating of 880 mA compared to the 15M101K's 830 mA, offering additional design margin in current-limited applications. Both components maintain identical inductance, tolerance, DC resistance, Q factor, and self-resonant frequency characteristics.

The 15M101K carries active product status with RoHS status listed as not applicable. The 1537-12K is also active but designated as RoHS non-compliant. Both components are REACH unaffected and classified under ECCN EAR99. Selection between these parts should consider compliance requirements specific to the end application and regulatory jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can the 1537-12K directly replace the 15M101K in existing designs?

A: Yes. Both components share identical inductance (1 µH), tolerance (±10%), DC resistance (290 mOhm max), Q factor (50 @ 25 MHz), self-resonant frequency (200 MHz), operating temperature range (-55°C to 125°C), and physical dimensions (0.156" Dia x 0.375" L). The 1537-12K's higher current rating (880 mA vs. 830 mA) provides additional margin without affecting circuit performance.

Q: What are the packaging differences between these parts?

A: The 15M101K is supplied in Tape & Reel (TR) packaging, while the 1537-12K is supplied in Cut Tape (CT) packaging. Both use through-hole axial mounting with identical physical form factors. Packaging selection depends on assembly process requirements and volume considerations.

Q: Are there compliance differences between the 15M101K and 1537-12K?

A: The 15M101K lists RoHS status as not applicable, while the 1537-12K is RoHS non-compliant. Both components are REACH unaffected. Applications requiring RoHS compliance should specify the 15M101K. Both parts carry EAR99 classification and fall under HTSUS code 8504.50.8000.

Q: What determines substitution eligibility for 1 µH axial inductors?

A: Substitution eligibility is determined by matching inductance value and tolerance, current rating capability, DC resistance specification, core material, shielding configuration, operating temperature range, and physical dimensions. The 1537-12K meets all these criteria for the 15M101K.
